How these individual arithmetic operations are carried out by the machine will be explained below. At this point of the description it should only be said that the machine is provided with three groups of totalizers or sum wheels, which are mounted on a shaft which can be moved transversely to the machine frame. Depending on the position of the shaft, the left, middle or right group is located in the area of sliding racks, at the front ends of which the printing types de;



  Addition mechanism. The shaft is connected by intermediate links to the paper slide of the machine, which, as in the case of the known typewriters, is automatically shifted around the space of a printing type when a key is pressed, taking the shaft mentioned with it.



   The paper slide can also be shifted laterally a certain distance in a known manner by so-called table tables 11m, in that the inhibition is triggered by pressing such a TabeMentaste so that the spring connected to the slide can move the slide, which after covering the distance is automatically held on again. In the present case there are four such table keys
Depressing the slide moves sideways and in a certain distance
Position is held up.

   This device is used, for example, when adding numbers in columns, whereby the numbers in the individual columns are exactly in line with one another.



   The connection between the paper carriage and the shaft carrying the sum wheels can also be released so that the sum wheels do not advance at the same time as the carriage. Behind the moving groups of the sum wheels is a rear group of
 EMI3.1
 occupies a fixed position at all times and can be brought into engagement with the same in connection with each of the front groups.

   In such a case the number registered in the respective front group is also registered in the rear group, and in the same way the sum registered in each of the front groups can be registered in the rear group. in such a way that the sums registered in the various front groups are all registered in the rear group, from which the general sum can then be printed.



   The sum wheels of the different groups are given a certain rotation. whereby, when the wheels are engaged with the rack carrying the printing types of the addir device, the latter are displaced so that the printing types are brought into printing position. The imprint j "Jr digit is made by special print hammers, which are triggered and, by being swung from below against the printing types, effect the printing of the same on the sheet of paper located in the paper carriage. The device is such that only the printing types il, the racks that are pushed forward and occupy a certain position in the machine frame.



   The set-up of the machine is now to be described, the individual sections being provided with suitable headings for the purpose of a better overview. Writing mechanism.

 EMI3.3
 



   The paper carriage consists of the frame, which can be moved on rails, and the frame 6 that accommodates the printing or paper roller. As illustrated in FIGS. 9 to 17, the paper carriage is provided with a toothed bar 6 which provides the inhibition, in FIG
 EMI3.4
 

 <Desc / Clms Page number 4>

 A plate 13 is hinged to the slide (FIG. 17), by means of which the locking pawl 7 can be disengaged so that the slide can move under the action of the force spring until it is stopped again. The plate 13 can be swung around its pin either by hand by means of a lever 14 (FIG. 16) or by one of the table keys D.



    Table keys.



   As can be seen in FIGS. 18 and 19, these table keys sit on levers 15, the rear ends of which are connected to rods 16. The upper ends of the latter are provided with a stop surface which lies under the plate 13 (Figure 17). A rod 18 is also arranged in the slide, to which adjustable stops 17 are articulated, which, as shown in FIGS. 9 and 17, lie in their normal position in incisions which are located in the front edge of the toothed rod 6. The upper ends of the stops 17 lie in incisions
 EMI4.1
 



   Briefly, the operation of this facility is as follows:
If one of the table keys D is depressed, the plate 13 (FIG. 17) is swung backwards by means of the lever 15 and the rod 16, whereby the clamping pawls 7 are disengaged and the carriage is pulled to the side. However, since the upper end of the rod 16 is lifted into the path of the lower end of one of the stops 17 after the plate 13 has swung out, the carriage is stopped as soon as the stop 17 in question meets the upper end of the rod 16. As soon as the table key is released again, the plate can swing forward again, whereby the locking pawls 7 are re-engaged.



   Effect of the addition buttons on the slide escapement:
As shown in FIG. 5, the key levers a connected to the keys of group A converge to the rear and are attached to a common pivot 27. The ends of the levers a, which continue to the rear via the pin 21, go under a plate 22 which is hinged to the free end of a bracket 23 (FIG. 110), the latter of which can swing around a rod 24. The bracket 23 is provided with a forwardly protruding extension 25 which rests on the lever 3 of the patient button (FIGS. 110 and 5). If one of the keys in group A is depressed, the rod 3 of the patient key is also depressed and the carriage is moved by one step by the release of the locking pawls 7.



   Locking the slide.



   When printing vertical columns, the slide must be locked against displacement so that the numbers come exactly under each other. For this purpose a de. Adjustable stops 17 are used in conjunction with one of the table keys D, which is depressed and then held down, in which case the upper end of the rod 16 influenced by the key D (FIG. 17) acts as a permanent stop. In order to hold one of the keys D firmly after it has been depressed, a post 26 is arranged on the side of one of the key levers 15 which, as shown in FIGS. 23 and 24, is provided with a nose under which the lever 15 can be pressed after the button is depressed, whereby the latter is held in this position.

   To release the button again, the rod 15 only needs to be moved to the side.



   Line spaces.



   So that the mechanism for creating the literal spaces is automatically activated when printing columns of numbers, the following device has been implemented:
As can be seen in FIGS. 11 and 12, an arm 27 is attached to the frame of the machine, to which a lever 28 is articulated. The end of the same is connected to a rod 29, the latter, as can be seen from Figure 3, is articulated at its lower end to a lever 30, which pits on a swing-mounted shaft 86, which with each movement of the on the side of the Machine arranged hand lever 79, as described below, is swung. Each time the shaft 86 is swung, the lever 28 is swung around its pivot on the support arm 27 by the connection described above.



  On the lever 28 sits a tab with two pins 31 (FIGS. 11 and 12), one of which is above and the other of which is below a rod 32 which is carried by swinging arms 33, the latter on the rod 18 carrying the stops 77 sit (Figure 9). One of
Arms 33 is provided with an extension to which a pawl 34 is hinged (Figures 13 and 13), which engages in the ratchet wheel 12 at the end of the paper roll.

Two or more blocks 40, the lower side of which is correspondingly cut out for this purpose, can be moved on this scale bar.

   A pin 41 is slidably mounted in each block 40, which is provided with a sharp edge 42 at its rear end and furthermore with a tooth 43 (FIGS. 20, 21) which, when the block 40 is moved on the scale rod 39 in FIG the cutouts located at the rear edge of the same occurs. The tooth 43 is pressed into the cutout by a spring 44 mounted in the block 40 and engages a projection on the pin 41, but can be disengaged by pressing against the pin 41. The sharp edges 42 located at the end of the pins 41 are located in the path of a movable stop 45 which, as can be seen in FIG. 2, is seated on a slide 46.

   The latter is connected at its rear end to a locking lever 47 (FIG. 3) which, when swinging out, allows the front sum wheels to move from right to left. These sum wheels are as shown in FIG. mounted displaceably on a shaft 48. The shaft 48 in turn is mounted in two plates 49, which at their rear ends around a shaft t? C can swing. At the end of the latter, a lever arm 51 is articulated, the free end of which is articulated to the end of the shaft 48. A spring 52 acting on the lever 51 tries to pull the same to the right in FIG.

   However, this movement is usually prevented by the toothed locking lever 47, the teeth of which with
Teeth 48a in the shaft 48 engage. However, every time the lever 47 is around his
Fulcrum is swung, whereby its teeth are disengaged from one of the teeth 48a, the spring 52 moves the shaft 48 with the buzzing wheels sitting on it to the right in FIG. 56.



   The movement of the lever 47 releasing the shaft 48 is effected by the pins 41 seated in the adjustable blocks 40 mentioned above. Namely, by gradually moving the paper carriage, the sharp edge 42 on one of the pins will meet the beveled surface of the movable stop 45 after a certain distance has been traveled.



  As a result, the slide 46 is pushed back and the lever 47 is released, which is swung around its pin by a spring so that the one tooth 4711 on the lever 47 comes into the path of one of the teeth 4811 on the shaft 48, so that the latter in a certain Position is held up, in which position a certain group of the front summing wheels comes into the printing position. When the next block 40 then hits the inclined surface of the movable stop 45 with the sharp edge 42 of its pin 41 during the further displacement of the paper carriage, the lever 47 is again swung around its pivot pin by the spring 52,

   that the shaft 48 is released and another group of sum gears is brought into the Ar1teih, - position. Since the blocks 40 are adjustable, the various groups of the sum wheels can be adjusted in certain positions of the paper carriage.



   When pushing the latter back into its original position, the total

   The keys in group A of the key board represent the addition keys and, as already described, sit on levers a, which rotate around the pivot 21 (FIG. 5). The rear ends of the levers a are bent and end under the lower ends of vertical rods 56 (FIG. 4), which are guided in plates and the upper ends of which are located under adjusting pins 62 (FIGS. 3 and 37), which are mounted in a sliding frame 57 are.



   Adjustment device:
As shown in FIG. 39, the frame 57 is provided with pollen which run in guide rails 58. The latter are hinged at one end to the frame of the machine (FIGS. 33 and 36), while at their other end they rest on a post 59 which is connected to one of the crossbars of the rail frame 58. At this end of the frame there is a drum 60 which is under the action of a spring and over which a belt 61 passes, the free end of which is attached to the frame 57 (FIGS. 37 and 38). The spring in drum 60 tends to pull frame 57 to the left in FIGS. 37 and 38.



   The arrangement of the number keys in group A and their key levers is chosen so that the key lever corresponding to the number 0 ends under the rearmost of the rods 56, while the key lever corresponding to the number 1 ends under the next rod u. s. w.



   Each of the rods 56 opposite at the upper end of the same is, as already mentioned, an adjusting pin 62, each of which is provided with cutouts 63, 64 forming stop surfaces (FIG. 39). The upper ends of the pins are also provided with beveled surfaces 65 which slide along the upper flange 66 of the frame containing the pins when the pins are lifted. Two pins 62 are connected to one another by springs 67, whereby the pins are pressed towards opposite sides and held in their upper and lower positions.



   Each row of these pins 62 comes in line with the rods 56 when the frame 57 is moved one after the other. If, for example, the number 123 is printed and registered in the sum wheels, the corresponding number keys in the group are displayed. A depressed in sequence.

   As a result, the rods 56 located opposite the corresponding adjusting pins 62 are lifted one after the other, whereby first the pin 62 marked "1", i.e. the second pin from the right in FIG. 39, then the pin marked "2", i.e. the second pin from the right in FIG. H. the third from the right in Figure 39 and then the one with ,. 3 ", i.e. the fourth from the right in FIG. 39
 EMI6.2
 in the manner described below, shifted gradually from right to back so that pins 1, 2 and - are hit in different rows.



   The raised pins 62 must of course be pushed down again after the registration has taken place. For this purpose, a rod 68, which is shown in FIG. 40, is arranged displaceably on the frame 58. The rod is provided with wedge surfaces which form sharp edges 69. If they come between the pins 62 when the frame 57 is displaced. in this way the support surface formed by the upper recess 64 is pressed away from the flange 66. Then, when the frame 67 is moved further to the right in Figure 37, the upper ends of the pins 62 come into contact with a beveled surface 70 on the underside of the rod 68, whereby the pins are pushed downward.

   This downward movement of the pins is supported by the KeiMäne 65 located at the upper ends of the pins.



   As shown in FIGS. 33 and 34, the frame 57 is generally in the right-hand position, and the pins 62 in the extreme left row are located under the stop pins 93 in the extreme right row. The pins in this row are affected by the decimal key D. in such a way that if one of the keys in group A and the decimal key are depressed at the same time, the frame 57 is not moved. If the hand lever on the side of the machine is then pulled, the button is in group. 1 set pin 62 lift the corresponding stop pin 93, whereby, as described below, a number with a decimal point in front of it is printed.



   On the frame 57 there is also an attachment 57 ″ (FIGS. 37 and 38) which lies below the stop pins ss corresponding to the number 6 '. The purpose of this attachment is to lift all the stop pins which are to the left of the row corresponding to the highest number lie, in which a stop pin is lifted, whereby an imprint of the higher numbers is avoided

   Registration of the numbers in the front sum wheels:
As shown in FIGS. 1, 66 and 67, a segment 109 is attached to the shaft 81, which is swung along with the hand lever 79 with every pull. At one corner of the segment there is a fixed stop 110 which counteracts when the segment swings forward
 EMI7.2
 is usually held in an upright position by a spring 114 (FIG. 1). In this position, a curved edge on the plate 112 rests against a plate 115 fastened to the machine frame. If the stop 110 on segment 109 hits against pin 111 on plate 112, the latter is swung around its pivot on rod 113, whereby the latter is pressed downwards.

   The parts remain in this position until the segment 109 swings back with the shaft 81 and has almost reached its original position. At this point in time, a stop 116 at the other corner of the segment 109 hits the pin 111 on the plate 112, whereby the latter is brought into its original position (FIG. 67) so that the rod 113 can go up again. The upward movement of the rod 113 takes place under the action of a spring 114 (FIG. 1), which lifts the rod and the plate 112 tapped on it so far that a pin 117 seated on the latter rests against the front edge of the rod 113, the pin 111 is lifted on plate 112 over the stop 116.



   At its upper end, the rod 113 is connected to the free end of the frame 49 containing the front sum wheels (FIGS. 1 and 25), which is suspended from the rod 60 (FIG. 3). If the rod 113 is moved downwards in the manner described, the front sum gears 119 are brought into engagement with their racks 100, so that the sum gears are rotated when the latter is shifted backwards (to the right in FIG. 25). When the hand lever 79 approaches its original position, the stop 116 comes

 Spring 114 engaging rod 113 lifts the rod and thereby the frame 49. As a result, the sum wheels 119 seated on the latter are lifted out of their racks 100 again.



  Device to prevent unnecessary forward movement of the racks:

 brought into engagement with their racks before the hand lever 79 is pulled forward. The wheels 119? 9 rotated backwards until a wide tooth 120 (FIG. 27) seated on it hits the lower end of a suspension arm 121 (FIG. 25), at which point the wheels are stopped in their zero position. As a result, the relevant racks 100 are shifted by such a distance that the correct sum is printed out of the printing types located in the racks.

   When the hand lever 79 approaches its front end position, the rod 104 causing the rearward displacement of the racks has run ahead of the levers 102 of those racks which were stopped before they reached their left end position in FIG. If, at this point in time, the sum wheels 119 are lifted out of their racks, the last-mentioned racks are pulled forwards by their springs (to the left in FIG. 25) until the levers 102 meet with the rod 104. In order to prevent this, however, and to avoid the resulting vibration, pawls 2 (J8 of springs 209 are engaged in the racks at the given time (Fig. 25).

   As a rule, the free ends of these pawls are held out of the area of the teeth of the racks by a rod 210 seated on arms 211. The arms 211 sit on a shaft 212, and the rod 210 lies in a slot of a slide 213 (FIG. 103) which is provided with stops 214, 215 on the lower side. The latter lie in the path of a pin 216 which is attached to one of the levers 105 carrying the rod 104

   Transmission device.



   Before moving on to the transmission device, the working process of the main organs of the machine described so far should be explained in brief.



   Those corresponding to the keys of group A and, when they are depressed, follow one another
 EMI8.1
 



  As a result of this device, each time selected keys of group A in the frame 57 are pressed down one after the other, a pin 62 in the transverse row corresponding to the number of the pressed key is raised in such a way that as a result of the step-by-step movement of the frame and the fixed disturbance of the rods 56 each subsequent one Pin 62 is in the next longitudinal row of frame 57. Should z. If, for example, the three-digit number 146 is printed or registered, the T's 6 of group A are depressed one after the other. As a result, three adjusting pins 62 are raised in the frame 57, the first of which is in the transverse row corresponding to the number 1 and in the first longitudinal row of the frame.



  The second pin lies in the transverse row corresponding to the number 4 and in the second longitudinal row, the third pin in the transverse row corresponding to the number 6 in the third longitudinal row. If the hand lever 79 is then pulled forward, the frame 57 with the three raised adjusting pins is raised, whereby three stop pins 93 are brought into position in the raised adjusting pins 62 corresponding to the transverse and longitudinal rows (FIG. 42).



   These three stop pins, which are in the first three longitudinal rows, serve to bring the toothed racks 100 into position when the hand lever 79 is pulled to the left in FIG. To each longitudinal row of the stop pins 93 corresponds to a toothed rack 100 which is mounted displaceably over its row in the longitudinal direction of the machine. In the present example, the first three toothed racks 100 will therefore move so far to the left in FIG. 25 that they are stopped by the abovementioned stop pins 93. Since the stop pins are in different transverse rows, the three racks will cover different distances in such a way that the first rack with its printing type 1 comes into the printing position, the second rack with its printing type 4 and the third rack with its printing type 6.



  The sum gears 119 (FIG. 25) arranged over the same can be brought into engagement with the racks 100. In the machine forming the subject of the invention, which is set up for a decimal system, each sum wheel has ten teeth. Each tooth corresponds to a printing type length of the racks 100, so that when e.g. B. a rack meshed with a Nllmnwnrad in ten transverse rows, d. H. moved ten pressure 1 ypen, the corresponding sum wheel is rotated ten teeth, d. H. the sum wheel makes one full turn around its axis.

   The transmission or registration device is arranged in the middle of the machine above the summing wheels in a frame, the walls of which 118 (FIGS. 1 and 25) serve as bearings for the axes of the various parts of this device.



   Each of the three groups of front summing wheels 119, once in the center of the machine, i.e. H. located above the racks 100, are brought into connection with these and the common transmission device, while the other two
Groups of the sum wheels are disabled.

In this way the addition of the numbers registered in the sum wheels is effected.



   As already mentioned and shown in FIG. 27, each of the sum wheels 119 is provided with a wide tooth 120 which, when the wheel makes more than one complete revolution, comes into contact with a suspension arm 121 which is mounted on one in the frame 49 Rod 122 is suspended swinging.

   The up and down movement of the rod 137 takes place by means of a rod 138 which is connected to an arm 139 seated on the shaft 136. At the lower end of the rod 138 is a plate 140 which is pressed by a spring 143 against a pin 142 on the rod 138 and is provided at its lower end with a pin 141 (Figs. 28 and 63).



   The pin 141 lies in the path of a stop surface. MJ on a thumb 82 seated on shaft 81, which is connected to the above-mentioned segment J 'dm-ch a sleeve 182 (FIG. 47), which sleeve can be displaced on shaft 81.



   When the thumb 82 swings forward with the shaft 81, the plate 140 on rod 138 is swung around its pivot against the action of the spring 143 (FIG. 63) by the stop surface 145 on the thumb 82 with the pin 141 on the plate 140 together

 hits, rod 138 is lifted with its parts, whereby the tooth arches 129, which are brought into engagement with the sum wheels 119 by sliding the arm '127 over the transverse rod 128 away (Fig. 29), are lifted out of the same again (Fig. 28), while the arm 127, which is provided with a cutout at its front end, is withdrawn into a slot in the rod 128. The parts assume this position when the hand lever 79 has reached its front end position and begins its backward movement.

   At this point in time, the sum gears 119 are in mesh. with the racks 100 as described above.



   At the end of the beveled surface 146 of the thumb plate 82 there is a tooth 147, by means of which the tooth arches 129 are moved a little further back than is necessary for their adjustment with reference to the wheels 119. As a result, the arm 127 connected to the dental arch through a slot and pins entering the same is moved so far back that the stop surface formed by the cutout at its front end is moved behind the rod 128 and the arm 127 is held until it reaches the Rotation of the sums wheels through the wide tooth 120 by means of the hanging arm 121 and the catch 124 in the

   On the shaft on which the angle levers 153 sit, there is an arm on which a rod 163 sits, which lies under the fingers 155 of the hammers (Fig. 54). The fingers 161 are also located in the circular path of the rod 163. The arms 162 are provided with lateral extensions in which a rod 164 is attached to which one end of springs 157 is attached, through which the hammers 156 are swung.



   Every time a rack 100 is moved forward, the rear end becomes the pawl. 162 is lifted off the arm 153 of the angle lever (FIG. 54), so that the pin 154 sitting on its other arm is pressed by the springs 157 against the finger 155 of the hammer.



  When the hand lever 79 is pulled forward, the rods 163 and 164 will be pushed downwards. This increases the tension on the springs 157 as the rod 163 comes into contact with the fingers 161 and lifts the arms 159 off the pins 158 on the hammers 156. As a result, those hammers, which have previously been released by lifting the arms 152, are thrown against the printing types located in the associated racks, whereby an impression is produced on the paper sitting in the paper carriage.

   As the stand stored in the arms 162 returns to its original position, the hammers in operation are also returned to their original position, in which they are held by the arm 159 provided with the tooth.



   At the same time, all the angle levers 153 are swung around their pivot point by means of the pins 154 in such a way that they are held by the arms 152 when the toothed racks are pushed back. An on the outside of the frame plate serves to swing the arms 162

   The other arm 177 of the angle lever 7 / J terminates via a pin 178 at the lower end of the already mentioned rod 113, which is connected to the frame 49 carrying the sum wheels. When registering numbers in one of the groups of the sum wheels 119, the rod 113 is moved by the thumb plate 109, as described. However, when the T key is depressed, the frame 49 is also moved downward through the rod 113 to bring the sum gears into engagement with the racks. The sum wheels are then rotated in reverse until the wide teeth meet with the hanging arms 121, causing the wheels to stop rotating wildly.

   Since the frame 49 is depressed by the thumb plate 109 when the hand lever 79 approaches its front end position,

   In order to enable a sum registered in the sum wheels to be printed after the T button has been pressed, the thumb plate 109 is provided with a hanging arm 186 (FIGS. 34 and 35) which fits into one of several grooves 187 which are in one of the Machine frame protruding post 188 are attached. When the hub 182 carrying the thumb plates 82 and 109 is moved laterally in the manner described by pressing the T button and pulling the hand lever 79, the arm 186 and plate 109 enters one of the grooves 187, whereby the Avoid parts held in place until hand lever 79 returns to its original position.

   When the hand lever approaches its front end position, the T button is released, whereby the sum wheels 119 are lifted from their racks. During the forward movement of the hand lever 79, the T key is held down by the aforementioned plate 176 (FIG. 68), which, however, releases the key when the hand lever approaches its front end position. For this purpose a pin 186 is attached to the arm 186 seated on the plate 109. attached (Fig. 63), which meets with the swinging of the plate 109 with a bent part of the plate 176, whereby the latter is moved away from the nose 175 and the latter is released.

   A spring 172h (FIG. 68) acting on the angle lever 172 returns the parts to their original position and the T button is lifted.



  However, if the sum is to remain registered in the sum wheels, 80 the T button must remain depressed until the hand lever 79 has returned to its original position. Hand lever:

 connected. As can be seen in FIG. 47, this sits at the end of a long hub 190 which loosely surrounds the shaft 81. At the other end of the hub 190 sits a lever 191 on which springs 200 act vigorously (FIGS. 104, 105), which endeavor to return the hand lever 79 to its original position after each pull on it. At the lower end of the lever 191 there is a pawl 193 which moves over the notched upper edge of a plate 194 (FIG. 105) which has its pivot point at 195.

   The free end of the plate 194 is supported by a knee joint 196 which, in the extended position, holds the plate 194 in the raised position. When the knee joint is kinked, the free end of the plate 194 goes down. In this position of the plate 194, the pawl 193 can be turned over so that the hand lever 79 can return to its original position under the action of the springs 200. However, as long as the knee joint 196 holds the rod 194 up, the hand lever 79 remains locked in its front position.



   A displaceable rack 197 is provided to bend the knee joint. A projection 198 sits on the same, which is located in the path of the lower end of a swing arm 199 which is attached to shaft 81. At the lower end of the arm. 199 are engaged by springs 192, which force arm 199 to follow the lower end of lever 191, with a pin 201 seated on arm 199, on which the springs 192 engage, resting against lever 191. As soon as the hand lever 79 is released by the downward movement of the rod 194, it is retracted into its original position by the springs 200, which are stronger than the springs 192.



   An arm 202, which carries a brake cylinder 203 (FIG. 35) which is filled with 01, is also attached to the shaft 81. In the cylinder there is a perforated piston, the piston rod of which can rotate about a transverse shaft 204. If the hand lever 79 is suddenly pulled forward, the lever 191 (Fig. 104) will run ahead of the pin 201 on lever 199, and the shaft 81 is swung under the action of the springs 192, with the brake cylinder 203 on arm 202 BO is moved so that the 01 in the cylinder is pushed through the holes in the piston.

   If, during the backward movement of the hand lever 79, the lever 191 rests against the pin 201 of the lever 199, the hand lever 79 not only has to overcome the tension of the springs 192, but also the resistance of the piston in the brake cylinder 203.



  The movement of the hand lever is therefore braked in both directions. Will the hand lever

The knee joint is stretched again and the plate 194 is raised again by a spring acting on the pin 196a of the knee joint and shown in FIG. 106. The movement of the knee joint is limited by a stop. When the arm 191 returns to its original position, the pawl 193 seated on it slides over the notches in the rod 194. The rack 197, by the displacement of which the knee joint 196 is buckled, is also used to return the frame containing the pins 62 to its original position, as shown in FIG.

   As can be seen from this figure, a toothed arch 205, which engages with the rack 197, is attached to the shaft. If the latter is displaced by the lever arm 199, the shaft 76 is rotated and the frame 57 is displaced accordingly by means of the toothed arch 77 and the rack 78 (FIG. 37) seated on it.



  Error key: As shown in FIGS. 2, 3 and 5, a rod 206 is slidably mounted in the machine frame, the front end of which is provided with a button. by means of which the rod can be pushed back. A collar 20'l (. Flg. 5) sits on the rod and lies far enough in front of the rack 197 to allow the rack 197 to move during the step-by-step movement of the frame 57. If, on the other hand, the rod 206 is pushed back, the collar 207 comes into contact with a rag sitting on the rack 197 and returns the rack to its original position.

Machine registered.

   Namely, as shown in FIG. 25, each of the levers 102 displacing the racks 100 is provided with a pin 217, by which the levers 102 and 102 ″ are locked with one another when they move forward (to the left in FIG. 25) while they are moving at the
Be separated again at the end of this movement. The levers 102 are then returned to their original position by the rod 104 in the manner described, while the levers 02a remain in their front position. In order to lock the levers 102a with the levers 102, the former are provided in their lower ends with a recess into which the shaft 106 enters (FIG. 69).

   The levers 102 are also provided at this point with a hook-shaped extension 218, soft on a
Plate 219 rest, a plate 219 attached to it grasping over the extension 218. The plate 229 sits on an oscillating shaft 220 on which a swing arm 221 is also seated, the free end of which is provided with pins 222, 223. One of these rests on one arm of a Wiukel lever 22, the other arm of which is articulated to a rod 226. The front end of the same is hinged to a lever 227 which is connected by a stand 226 'groove of the "R" key.

   If this is depressed, then by the described
Connections lifted the plate 219, whereby all levers 102a also lifted and by means of the pin 217 on the levers 26.? be locked with these. If the hand lever 79 is now pulled forward, the levers 162, which are also swung forward as a result, take the levers 102 "with them. When the hand lever reaches the end of its forward movement, the plate 176, which interacts with the rod 174, is behind a Nose 229 on the
Rod 226 is lifted, whereupon a tensioned spring 230 acting on the lever 227 returns the parts establishing the connection between the "7?" Key and the plate 219 to their original state

  From every rod. A transverse arm 247 projects to the side 244, the free ends of which are guided in vertical grooves in a housing plate. A spring 248 acts on the end of one of these rods 247. These crossbars 247 come under the hanging sliders 235 (FIG. 77) which are arranged on the cross arms 236 of the rods 239. The sliders 235 are adjusted, as described above, by the movement of the levers 102 when the hand lever 79 is pulled forward .

   Depending on the position of the lever 102, which also determines the position of the slide 235, the stop rods 239 are raised more or less during the upward movement of the rods 244 by means of the transverse arms 247 that step under the slide 235, and depending on the pins 242 at the rear ends of the racks 100 come into contact with one of the stop surfaces "0" to "9" on the extension 243 of the rods 239, the racks 100 are held in a certain position.



   The transverse arms 247 seated on the rods 244 are lifted by peculiarly shaped plates, which are referred to below as "selector plates". A complete set of these plates is illustrated in Figures 78-96. Before describing the means of activating these plates, a brief explanation of their function should be given.



  For each digit, with the exception of the digit "O", two dial plates are provided, one of which represents the tens and the other represents the one of the partial product. The end product is then obtained by adding the two partial products. The dial plates shown in Figures 79 to 87 are the tens plates, while the plates shown in Figures 88 to 96 are the units plates. Each of these plates corresponds to one of the digits., 1 "to" 9 ". The plate shown in Fig. 78

   If, for example, the number 654 is to be multiplied by 9 in order to make the mode of operation of the dial plates clear with a concrete example, the number 654 is first set up by pressing the relevant keys in group A, after which the "R" key is pressed. By pulling the hand lever 79, the number 654 is registered in the manner described in the front sum wheels, and through the intermediary of the lever 1020
 EMI13.4
 key labeled "9" is depressed, whereupon the hand lever 7Y is pulled forward twice. In order to obtain the end product, the f key is finally depressed and the hand lever 79 is pulled forward.



   When one of the keys in group B is depressed, a plate 251 is moved by the levers 250 connected to the same. (Figures 3 and 5). The latter is provided at its rear end with a vertical slot in which a pin 252 on the lower arm of a double lever 253 enters (Fig. 7). The upper arm of the lever 253 is usually below one arm of an angle lever 254, which is pressed down by a spring 255. If the upper arm of the lever 253 is pulled away from under the arm of the angle lever 254, the latter is swung around its pivot point, the movement being limited by a pin 256 which passes through a slot in one arm of the angle lever 254 (Fig. 7 ).

   The angle levers 254 are tapped on the guide spindles 257 of the tens plates shown in FIGS. 78 to 87 (see also FIGS. 97 and 98). Each of the decimal plates consists of a head part 258 which is provided with steps and is located on a lead screw 257. The steps are arranged in such a way that, depending on the setting of the head part 258, which is determined by one of the keys depressed in group B, the cross bars Put 247 in a certain position.



   When one of the keys in the B group is depressed by means of the lever 250 connected to the key and the plate 251 connected to it, the double lever 253 is swung around its pivot, so that the upper arm of the same is under one arm that on the guide rod 257 the angle lever 254 tapped on the "tens" plate is pulled away, the other arm of the angle lever is brought into the area of a rod 259 which is moved vertically up and down and which is inserted into slots in the frame enclosing the selection plates.

   while the sum wheels are raised again at the end of the return of the hand lever to its original position.



   The displacement of the thumb plate 109 on shaft 81 upon depression of one of the keys in the "B" group takes place in the following manner.



   As shown in FIG. 7, each of the plates 251 connected to the key levers 250 of the keys in group "B" is provided with an upright projection 275 which cooperates with a knee joint 276 which is connected to one arm of a shaft 278 seated on a vibrating shaft Double lever 277 is bound. On the same shaft there is also an arm 279 (Fig. 65) which lies under one arm of an angle lever 180, the other arm 181 (Fig. 63) of which is connected to the hub 182 on which the plates 109 and 82 are seated (Fig. 35).

   If one of the keys in group "B" is depressed, the described connections move the plate 109 so that its stops 110 and 116 meet the pin 274 on the plate 273 when the plate swings, whereby the rear sum wheels are supported Frame is swung. In this position of the plate 109, the arm 186 of the same enters the upright recess of the post 188 (Fig. 35), whereby the parts are held in place until the hand lever is pulled forward twice.

 which the stepped head 2M sits.

   The steps are arranged in such a way that when the biner "plates are raised they meet with the cross arms 247 and through the same adjust the stop rod 239 so that the one" product is registered which is added to the previously registered "tens product, to get the multiplication, but this addition only takes place after the rear sum wheels have been shifted one step to the left.



   As shown in FIGS. 79 to 87, the guide rod 257 of each ten-digit plate is provided with a wedge-shaped, pointed projection 282 which, when the ten-digit plate is lifted, meets a pin 283 at a pawl 284 (FIG. 99) which usually under one arm of an angle lever 285, which is attached to the guide rod 280 of the corresponding "one".



  Plate is tapped. By lifting one of the "tens" plates, the angle lever 2S5 of the corresponding "ones" plate is released so that when the rod 259, through which the "tens" plates were lifted, goes down again, it goes under the downward arm of the angle lever 285 occurs and with the second pull on the hand lever 79 the relevant ,. One "plate lifts.



   A spring 286 acts on a lateral projection on each of the double levers 253, which serve to hold the angle levers 254 tapped on the guide rods 257 of the "tens" plates in position, through which the double lever after lifting the plate in question is moved so that when they move downward, the angle lever moved to the side is swung back into its original position, so that the next upward movement of the rod 259 does not take the "tens" plates with them again. For the same purpose, a spring 287 engages a short arm of the pawls 284 holding the angle levers 285 in position on the units "plates, so that the angle levers 285 are moved back to their original position when the .. units" plates move downwards.



   The "one" plates lifted with the rod 259 likewise take the transverse rods 247 with them, however. that they assume a direction opposite to that in which they were previously brought by the raised "tens" plates. Here, the stop rods 239 are pushed into the corresponding positions by means of the slides 235 such that those racks 100, their associated sum wheels are not should be rotated from being prevented from shifting.



   As shown in FIGS. 58 to 62, the shaft 269 carrying the rear sum wheels is provided with ratchet teeth 2M, into which a pawl 289 can enter, which is attached to one arm of a
 EMI15.1
 End engaging spring 292 held with ratchet teeth 288 on shaft 269 engaged. The other arm of the lever 290 lies in the path of a beveled pawl plate 293 (FIGS. 7 and 8) which is hinged to the upper end of a rod 295 and is held by a spring 294, typically in the position shown in FIG is held. The rod 295 is slidably arranged in vertical guides which are attached to the side plates 2-? 7 connecting crossbars are arranged. Each of the "one" plates is, as shown in Figures 8 to 96, with a protrusion '296
 EMI15.2
 



   If the "one" plates are lifted when the hand lever 79 is pulled for the second time, the knee joint 276 (FIG. 7) is simultaneously bent by the rod 295. For this purpose, the upper link of the knee joint is connected to an arm 27a, which one with a
 EMI15.3
 the rod 295 seated pin. This comes into contact with the upper end of the slot during the upward movement of the rod, whereby the arm 276b is pulled upwards and the knee joint 276 is buckled. When it is stretched by the projection 275 seated on the rod 251, the slotted arm 276b is drawn downwards.



   Under the arm 290 (Figure 7) is a second arm 298 by which the shaft carrying the rear summing wheels is locked against displacement while the pawl 289 enters a new tooth on the shaft 269 (Figures 60 and 62). As shown in Figure 56, both arms 289 and 298 are provided with lugs that attach to a pin on one arm of a double

 EMI16.1
 and by adjusting the paper carriage for these columns, arms 289 and 298 affecting the incremental displacement of shaft 269 carrying the rear sum wheels are disengaged,

   so that the rear sum wheels can be returned to their original position for a new example.



   If the product of the rear totalizing wheels is to be pressed, the "" P key is depressed and the hand lever 79 is then pulled forward once. As a result, the product is registered in the front totalizing wheels at the same time, so that if several products are to be added, by pressing the "T" key, the total can be printed.



   Printing the product:
As can be seen in FIG. 70, a rod J is connected to the "P" key, the rear end of which is connected to one arm of an angle lever 303, the other arm 304 of which lies over the pin 183 which is at the lower end of the above-mentioned rod 185 sits. By depressing the "P" key, this rod is also moved downwards and thereby the arm 84 is moved away from the area of the pin 83 on the thumb plate 82 (FIG. 68). As a result, the frame 58 carrying the frame 57 is not lifted and the Stop pins 9. 3 remain in their position.

   One end of a rod 305 is connected to the double lever 303,
 EMI16.2
 is held down by the "P" key until the hand lever 79 is at the end of its forward movement. At this point the plate 176 is swung upwards in the manner already described, whereby the "P" key is released again.



   The rear end of the rod 305 is connected to one arm of an angle lever 307, the other arm 308 of which lies over a pin 309 at the lower end of the rod 272. Thus, depressing the "P" key moves that rod downward, lowering the frame 270 containing the rear sum wheels so that the wheels are engaged with their racks.

   The angle lever 307, 308 is provided with an arm 310, which lies under the pin 223 on the arm 227 seated on the shaft 220. If the shaft 220 is swung when the "P" key is depressed, the plate 219, 219a seated on it is swung along with it, in such a way that the levers 102 are moved upwards, but not far enough Lock lever 102 (igur 70).

   The teeth 233, however, which are formed on the rods 237 articulated on the Hf eln102a (FIG. 25), are made from the racks 233

 Rods 231, through which the position of the hanging arms 235 for setting the stop rods 239 is determined, are returned to the zero position.



   An angle lever 311 (FIGS. 70 and 7) is used to return the levers 102 .., our arm of which lies above the arm 310 of the angle lever 307, 308, while the upper arm 372 engages a hub 313 which is slidably mounted on shaft 106 (Fig ) at which one

 returns to zero.



   If the "P" key is held down until the hand lever 79 returns to its original position, the rear sum wheels are kept in mesh with their racks and the product is again registered in the rear sum wheels.



   Thus when the arm 310 of the angle lever 307, 308 (FIG. 70) is raised, the arm 180

 left out.



   Each time a key in the "B" group is depressed, the thumb plate 82 is moved sideways, thereby moving it away from the pin 167b (Figure 63), and the rod 163 releasing the print hammers 156 is not swung (Fig. Device for correcting errors in the multiplier Facility :

 which, as can be seen from FIG. 5, protrudes beyond the rack 197. The end of the lever 206 is in a line with the lower arm of an angle lever 319, which is provided with a hook-shaped projection 320 (FIG. 73).

   The latter is located in relation to the pivot pin 321 connecting the links of the knee joint 276 that if the angle lever 319 is swung around its pivot pin when the button is pushed back, the knee joint 216 is bent by the hook-shaped projection 320, whereby the laterally displaced thumb plates 109 and 82 can be returned to their original position by the extension of the knee joint. At the same time, a rod 323 is lifted by the other arm 322 of the angle lever 319, on which an arm 324 sits (FIG. 74), which is below the directed types of angle levers 254 and 285, which are hinged to the tens "and units" plates shown in FIGS. 78 to 96.

   Those of the Wi1lkelhf'bel, which from their handles 253 resp. 283 were lifted off, so when the rod 323 is lifted by the arm 324 sitting on it, they are returned to the position shown in FIG. 99 position shown raised.



  Transmission of a registered in the front sum wheels
Number in the multipliers:
This process is carried out by the key labeled "Eu" with which, as in FIG
71, a lever 325 is connected. The rear end of the same is connected to one arm of an angle lever 326, the other arm 327 of which lies above the pin 183 which is located at the lower end of the rod 185 already mentioned. So if by pressing the
 EMI17.2
 a (Fig. 71), thereby holding the "E" key depressed until the hand lever 79 reaches the end of its forward travel. The other end of the rod 328 is connected to one arm of an angle lever 329, the other arm 330 of which lies over a pin 178 which sits on the lower end of the rod 113.

   Since the latter, as described above, is connected to the front end of the frame 58 carrying the front summing wheels, this frame is moved downward when the "E" key is pressed, whereby the summing wheels are brought into engagement with their racks. On the angle lever 329 there is also an arm 331, which lies under the pin 222 on the arm 221 seated on the shaft 220. As seen in Fig. 71, the pin 222 is closer to the axis of rotation of the shaft 22C than that
 EMI17.3
   11m is given such an angle that the levers 102a are locked with the levers 102 in the manner described above. If the hand lever is then pulled forward, the racks are also moved forward.

   The cross arms 231 (FIGS. 25 and 77) connected to the levers 10280 entrain the sliders 235 and adjust them according to the position of the racks. At the end of the forward movement of the hand lever, the "E" key is released, whereby the levers 102 are released from the levers 102 again. The teeth 232 on the transverse arms 231 engage the teeth of the racks 233, whereby the slides 235 are fixed in positions determined by the racks.



   If the number previously registered in the front summing wheels is to remain registered in the machine, the "T" key is depressed, whereby the relationship between the front summing wheels and the toothed racks is maintained, so that when the hand lever moves backwards the Racks are returned to their original position, the number in the front sum wheels is registered again.

   Each time the "E" key is depressed to transfer the number registered in the front summing wheels to the multiplier, the number is imprinted by the print hammers and the front summing wheels are released when at the end of the forward movement of the hand lever the "E" key is released. If, on the other hand, it is held, it
Number registered anew in the front summing wheels.



   The decimal key:
The "D" designated decimal key sits on a key lever 340, the rear of which
End is connected to a lever 347 (Fig. 72), which at its upper end a rod 342

 so the keys corresponding to the individual digits are depressed and while the key corresponding to the decimal place 5 is depressed, the "D" key is depressed at the same time, whereby a rack 100 "which is to the right of the" one "rack 100 is activated is located. As shown in Fig. 51, the rack 100a is not provided with a "0" type because it is unnecessary.

   Typically, when a key in group A in frame 58 is depressed, a pin 63 is raised (FIG. 39), and when the key is released, the paper carriage is moved one step to the left. However, if the "DU key is depressed, the inhibition is deactivated, and if a key in group A is then depressed, the paper carriage stops, with the pin 63 corresponding to the number under the relevant number or printing type in the When the hand lever is pulled, the toothed rack 100a is moved into the pressure position in the same way as the other toothed racks, because a sum wheel is also provided for the toothed rack 100a.

   As shown in Fig. 51, the printing types on the rack 100a are provided with one decimal place.
 EMI18.2
 



   The following device is provided so that a decimal place registered in the machine can be printed:
As shown in Figs. 42 and 44, a lever 354 is hinged to the crossbar 91, the

   The multiplication of a decimal number:
Assume that the decimal number 0.4 has been registered. If in this case the "R" key is depressed when pulling the hand lever forward, this decimal number is printed and the corresponding slide 236 of the stop rod 239 is also set and
 EMI19.1
 Plate 90 is tapped and is under the protruding end of the lever 364 (Fig. 45). The other end of the latter is connected to a rod 357 which, as shown in FIG. 74, is guided vertically on a frame plate.

   A pin 358 is seated on the rod 367 and projects under the rod 259, as a result of which it returns the rod 357 to its original position. Weigh Figs. 75 and 76 shown. the Starge 357 is also provided with a transverse arm 359 which can engage both with the stop surfaces 296 of the "back" plates and with stop surfaces 360 of the "ten" plates. Since the stop surfaces 360 are shorter than the stop surfaces 296, the raised "tens" plates will carry the rod 357 with them, while the rod 295 remains undisturbed, whereby the rear sum wheels are moved gradually.

   When one or the other of the "one" plates are then raised, the cross arms of the rods 295 and 357 are raised by their stop surfaces 296, whereby these are also raised and the rear summing wheels are given a step-by-step movement. At the same time, the lever 356 is swung so that the rack 100 is released every time a plate of the multiplier is raised.



   Decimation of the product:
In order to eliminate unnecessary decimal places, a key 367 is provided in the keyboard of the machine (Fig. 2). A key lever 362 is connected to this key (FIG. 41). As shown in FIG. 3, this lever is connected to an arm 363 which is seated on a vibrating shaft, at the other end of which an arm 364 is attached. A rod 365 (FIGS. 59 to 62) sits on the latter, the upper end of which is beveled and is located next to the frame 270 containing the rear sum wheels. As shown, the pawls 289 and 298 are provided at their free ends with extensions which lie in the path of the beveled upper end of the rod 365 (see also FIG. 56).

   If the latter is lifted by the button 361, the straight edge of the bar moves in front of a ratchet 288, while the beveled edge moves the pawls 289 and 298 out of their teeth (Fig. 62). The rear sum wheels are now moved by the spring 366 until they are stopped by the ratchet behind the rod 365. When the button 361 is released and the rod 365 is thereby spotted, the pawls 289 and 298 are released, resting on the ratchet teeth with which they were previously engaged.

   Thus, when the rod 365 is withdrawn from its ratchet tooth, the rear summing wheel group of the spring 366 is pulled one step to the right. This "can be repeated as often as the product is to be decimated in the rear sum wheels.



   In the illustrated embodiment of the machine, two extra wheels are provided in the rear group of the sum wheels, which are intended for any additional decimal places.



  In most cases, however, these decimal places will be eliminated from the product, since two decimal places are usually sufficient. For this purpose, a number of racks corresponding to the number of extra rudders is provided, the latter being designated by 1000. As can be seen in FIGS. 30 and 32, these racks are not provided with printing types at their front ends, nor do they have any teeth with which the front sum gears can mesh.



  These racks are provided with pins 367, which are usually behind bars 368, from which arms 369 project backwards. As shown in Fig. 42, the arms 369 lie over the end of a lever 370, the other end of which cooperates with an extension 3. on the rod 272 (Fig. 45). The rod 272 is known to be connected to the frame carrying the rear sum wheels.

   Every time, that is, when the rear sum wheels are brought into engagement with their racks by the rod 272, the racks 100 ″ are released.
 EMI19.2
 

 <Desc / Clms Page number 20>

 Grand total can now be registered and printed in a special group of the front totalizing wheels by depressing the "PU key and holding it down, while the hand lever is pulled forward and goes back to its original position.



   With the racks 100t, levers 102 are connected in a similar way as with the other racks, on which springs act, by means of which the levers and thereby the toothed bars are moved forward. The rod 104 serves to return the toothed racks to their original position. The toothed racks 100b are only released during the printing of products.

   The pawl holding the rack 100a, which is influenced by the lever 354, is disengaged with every pull on the hand lever. Since the release of the pawl takes place after the front sum wheels have been brought into engagement with the rack, it is clear that when the sum wheel that is in engagement with the rack 100th is in the zero position, the rack stops, and before the sum wheel is withdrawn from the rack, the pawl has returned to its original locking position. If, on the other hand, the sum wheel engaged with the rack 100 is not in the zero position, the forward movement of the inner rod can be prevented by the pawls 208 (Fig.

   30), which can also hinder the displacement of the rack 100 ″.



  Blocking the idle sum wheels against accidental rotation:
As shown in FIG. 56, a rod 37 is provided, the edge of which can engage with those summing gears which are not in engagement with their toothed racks. The edge of the rod 275 is recessed so that the sum gears engaged with their gears can rotate. In a similar way, the rear group of sum wheels is provided with a rod 376 which, when these sum wheels are shifted to the left after one another, engages with the forward sum wheels and locks them against displacement.



   In FIG. 102 a toothed rod 104 is shown, the teeth of which are pointed. These tips come between the rods 102 and 102a so that they cannot frictionally engage each other as they swing forward.



   The preceding description of the setup of the machine and its operating location should now be followed by a few brief explanations of the types of invoices mentioned at the beginning that are automatically executed by the machine:
1. Linear addition:
In the example given, the keys labeled 1, 2, 3 in group 4 are first pressed down one after the other. Then the "D" key is pressed to open the
Register the number 123 in the rear sum wheels, whereupon the hand lever 79 is pulled forward.

   When the latter reaches the end of its forward movement, the D "key is praised. By pulling the hand lever 79, the number registered in the rear totalizing wheels is printed simultaneously on the sheet of paper located in the paper carriage.
The paper slide is then shifted to the left by elite short sticks by pressing the Spatient button, whereupon by pressing the buttons with the numbers 4, 5, 6 in group A, the Tough! 456 is pressed. Again, the. D "key is pressed and the hand lever 79 is pulled forward.



   The paper slide is shifted to the left again to create the necessary space, and the third number 789 is now registered and printed in the same way.



   Instead of the space key to create the spaces between the three numbers, the table key "1" can of course also be used.



   In order to obtain the sum of the three numbers, the paper slide is first moved further to the left in order to obtain sufficient space for the print of the number representing the sum. The "P" key is then depressed and the hand lever 79 is pulled forward. If the "P" key is released at the end of the forward movement of the hand lever 79, the rear sum wheels return to the zero position. If, on the other hand, the "P" key is held down until the hand lever has returned to its original position, the total remains recorded in the sum wheels and can be printed repeatedly.



   In the case of linear addition, the "D" key is depressed, since the three groups of the front summing wheels, as described above, are taken along with the lateral displacement of the paper carriage, so that none of the groups assumes the correct position with respect to the racks 100 containing the printing types when the various numbers to be added are registered in the front sum wheels.

   If, on the other hand, the connection between the paper slide and the front summing wheels is made ineffective, one of the three will pass
Groups of the front total gears, regardless of the displacement of the Ppaierschlittens assumes a certain position in relation to the toothed racks, the "D" key does not need to be depressed.

   2. Addition in parallel columns:
In this example, the numbers appearing in the first column are first registered and printed out by pressing the relevant keys in the "A" group, but when the hand lever 79 is pulled, the device for producing the line spaces is activated so that the numbers be placed under each other. The total is printed at the foot of the column. The paper or printing roller is then turned back by hand, and after the paper carriage has been shifted sideways by a sufficient distance. the numbers of the second column are registered and printed, whereupon the total is printed again at the foot of the column. The same procedure is used for the third column.



   Instead of pressing the column of numbers one after the other, the top three numbers can also be printed using the table key, as with linear addition, and so on. s. f.



  By moving the paper slide from right to left (from the typist's position), the three groups of front wheels are successively brought into the correct position with respect to the racks 100, so that each column is added independently of the other.



   To print out the individual sums at the foot of each column, the "T" key is pressed after the paper slide has been set so that the digits of the sum come exactly below the digits of the numbers to be added.



   If the paper slide is then shifted to the left, after precise adjustment of the same, the sum of the second column is printed out with the help of the second group of the front sum wheels, and in the same way the sum of the numbers in the third column al) is printed after the third group the front summing gears is set in the correct position in relation to the racks. If the total of the three individual sums is to be printed out, the "D" -Ta is displayed each time the T key is pressed; ; te, whereby the individual sums are registered in the rear sum wheels, with the aid of which the total sums are printed out by pressing the "P" key.



   3. Addition in column n and multiplication.



   In this example the number 123 is first registered and printed out by pressing the relevant keys in group A and pulling the hand lever. Before pulling the hand lever, however, the "H" key is depressed, whereby the number 123 is registered in the multiplier. Since the number 123 is to be multiplied by the number 12. The latter number can be obtained by depressing the relevant keys printed in a limo with the number 133 on the sheet of paper located in the paper sled on the normal keyboard of the machine.

   However, in order to obtain the product of 123 # 12, namely 1476, the following procedure is used. Of the keys in group "B", each of which is given a number from "0" to "9", the key marked with "1" is first depressed and then the hand lever 7. 9 is pulled forward twice the key provided with key 2 in group B is depressed and the hand lever 79 is again pulled forward twice.



  Thereby the product of 12: 3 X 12 is registered in the rear sum wheels. After the paper carriage has been moved sideways, the product can be printed by pressing the "P" key and pulling the hand lever. When the P "key is pressed, the product is in the group in front Sum wheels are registered which are located opposite the racks 100 at this point in time.



   The paper slide is then shifted to the right, and after creating a line space the second number 456 is registered and printed in the manner already described. l'111 then to multiply this number by the number 54. is done in the same way with the Multi. proceed in the first row. By first depressing the key provided with the number 5 "and then the key given the number" 4 "after the number has been printed using the keys of the known writing mechanism, and after each of these two keys has been depressed, the hand lever is pulled twice. whereby the tens and units are set and the product is registered in the rear sum wheels.



   After setting the paper carriage accordingly. can by depressing the "T". Key and pull on the hand lever, the sum of the numbers in the first column

   4. Linear addition and multiplication.



   The execution of this example is initially carried out in the same way as for the first example.



   In order to multiply the sum 1323 by 83 / ", the number 83f. Must be displayed as a decimal place 8, 75, whereupon the procedure described above is followed by successively pressing the digits 8, 7, 5 in the JB "Group, and after each of these buttons has been depressed, the hand lever 79 is pulled forward twice.



  As a result, the product 11756, 25 is registered in the rear totalizer wheels and printed out by pressing the "P" key and pulling the hand lever. In order to then subtract 5%, the product 11766, 25 is multiplied by. 05 and the product is subtracted from this from the first product 11756, 25. However, to get the product less than 5% immediately, the number 11756.25 is multiplied by 0.95.

   In this case, after the number 11756, 2 ') has been set by pressing the "E" key and pulling the hand lever in the multipliers, first the one with the number "9" and then the one with the number " 5 "key in group" B "is depressed and after each key has been depressed, the hand lever is pulled forward twice. Then the decimal key is depressed twice, whereupon the P "key is depressed and the end product is printed out by pulling the hand lever through the intermediary of the rear sum wheels.



   5. Taxation tables.



   This calculation is carried out in the same way as that under 3, by first registering the numbers in the first column in the sum wheels and printing them and also registering them in the multiplier. The multiplication is then carried out in the manner already described, and finally the numbers in the first column and the products in the second column are added. Since the multiplications in this example are also decimal numbers, the decimal key is also depressed.



   6. Statement of costs.



   In this case it is a matter of multiplication, which has already been described.



   7. House rent table:
Here it is only a question of adding two columns. When calculating the commission (commission), the number 50 is first followed in one case
Depression of the relevant keys registered in group A and transferred to the multiplier device by depressing the "R" key. The number marked "1" is then displayed
Press the button in group B and pull the hand lever twice
Product registered in the rear hump wheels.

   Since it is the multiptizirun of 50 with .01,. The decimal key is depressed twice and then the "P" key, whereby the product, 50 is printed and at the same time registered in the front sum wheels.
 EMI22.1
 
 EMI22.2
   Numbers are registered for later addition, whereupon each number is registered with a multiplier. Further numbers are then added to the first two products. (linear addition).



   9. Potentiation of a number:
In the first case the number 12 is multiplied by itself once and in the second case twice. In the latter case, after the number has been struck once by the entering keys in group A, the "R" key is depressed and the hand lever has been pulled forward, the groups of the front sum wheels are shifted to the left, so that a new group with the racks is in Intervention occurs.



   If this shift of the front sum wheels is to be avoided, then the will be
 EMI22.3
 even multiplied. The P "key is depressed and the hand lever is pulled forward. This returns the rear totalizer wheels to the zero position and the product is registered in the front totalizer wheel. If the" E "key is now depressed, the product becomes the one time The number multiplied by itself is transferred from the front summing wheels to the multiplier, whereby the front summing wheels are returned to the zero position. For the purpose of the second multiplication, the

 <Desc / Clms Page number 23>

 
 EMI23.1
 is registered in the rear sum wheels.

   This product can then be printed out by pressing the f key and registered in the front sum wheels.



   10. R a b a t t b e r e c h n u n g:
This calculation is carried out as follows. The quoted price of an item is set by depressing the appropriate buttons in group A, then depressing the "R" button and pulling the hand lever forward. The front summing gears are then shifted to bring a new group into mesh with the racks. Since the first discount is 80%, the number 10 is multiplied by 100 less 80 equals 20%, i.e. by .20.



  The decimal key has to be pressed twice before the hand lever is pulled forward. The product is obtained by depressing the P "key and pulling the hand lever, whereby the product is registered in the vonlaren sum wheels. The r) i" "key is then depressed, whereby the product is transferred to the multiplier, while the front sum wheels go back to the zero position. The second discount 100 less 7% equal to 93% is now calculated in the same way and the product, like the first, is transferred to the multiplier. This product is then multiplied by the third discount, namely by 11 less 2% equal to 98%, thus obtaining the final product.



   Repeating a number: There are two methods of repeating a number in the sum wheels as you like without pressing the relevant keys each time:
The number is set up by depressing the relevant keys in group A, whereupon the paper roller holding the sheet of paper is swung back so that the number is not printed. Depressing the "D" key records the number in the rear totalizing wheels. The platen is swung back to its original position and the "P" key is depressed and held while the hand lever is pulled forward as many times as the Number to be repeated in the front sum wheels.

   Then, when the "P" key is released and the "T" key is depressed, the sum of the number registered in the front sum wheels can be obtained.



   Or the number to be repeated is recorded in the usual way in the front total riders, with the paper roller being swung back so that the number is not printed. By then depressing and holding the "D" key, the number can be repeated and printed any number of times, as well as added in the rear totalizing wheels. Then the "D" key is released and to get the total, the "P" key pressed down and the hand lever pulled forward.



   Only when it is to be multiplied will if a Ta.; In group "B", the lever is pushed forward twice, with the exception of the "C" key, in which case the lever only needs to be pulled forward once. For all other calculations The hand lever has to be pulled forwards only once.When the hand lever returns to its rear end position, the sum wheels always return to their zero position.



   When multiplying, the number of the highest order is always struck first and after depressing each number the hand lever is pulled forward twice, as already mentioned, whereby the rear sum wheels are shifted one step to the left for each number.



  As soon as the product has been printed, the rear sum wheels are automatically returned to their original position.



   Finally, it should be mentioned that the numbers on the keys in group S "preferably have a different color than the numbers on the keys in group" A ".
