Definitions

  • This invention relates to accounting machines
  • the pressure rolls are secured to a bail extending across the front of the carriage, and as the bail is moved away from and toward the platen in moving the pressure rolls, this operation will be referred to as opening and closing the front feed bail.
  • a further object of the'invention is to provide a mechanism of this character that is simple in construction, adjustable for operation at any desired point in the carriage travel, and which is capable of opening and closing .the carriage any desired number of times during each lateral excursion thereof.
  • Figure 4 is a right side elevation showing the operating mechanism for the invention and showing the adjustability of oneof the parts
  • Figure 6 is a back elevation showing some of the parts shown in Figure 4,
  • Figure 7 is a right side elevation showing the bail opening .and closing mechanism in its normal position
  • Figure 8 is a view similar to Figure 7 showing the device at the completion of its working strok in opening the front feed bail
  • Figure 9 is a view similar to Figure 7 showing the device at the end of its working stroke in closing the front feed bail
  • Figure 10 is a right side elevation of a modifled form of the invention showing the mechanism in its disabled position
  • Figure 5 is a side sectional view of one of the l Figure 11 is a view similar to Figure 10 showi ing the mechanism at the end of its working stroke in opening the front feed bail, and
  • Figure 12 is a view similar to Figure 10 showing the mechanism in its normal position.
  • the accounting machine I has a traveling paper carriage 2 with side walls 3 and 4.
  • the carriage is movable laterally of the machine on a track 5.
  • a front feed bail 6 extends across the front of the carriage in front of and above a roller platen I to accommodate worksheets inserted downwardly into the machine in front of the platen.
  • the bail 6 carries a suitable number of front pressure rolls 8 and is pivotedat 9 ( Figure '7) at each side of the carriage for movement forward and rearward of the machine under control of a detent ll pivoted to the bail at II.
  • a spring I connected to detent I I and to the frame of the paper carriage holds detent H in engagement with a stud M on the carriage frame.
  • Two recesses l5 and IS in detent ll determine the forward and rearward positions of the ball 6.
  • opening and closing front feed ball 6 is operated by lateral movement of the carriage, the bail being closed when the carriage moves from right to left on'its working stroke, and opened when the carriage moves from left to right on its return stroke.
  • the mechanism for operating the front feed bail in these movements includes a cam member I! ( Figures 2, 3 and 4) secured on a bracket l8 by a screw 2
  • Bracket l8 supports a rod 22 ( Figure 6) extending between its side flanges and secured thereto by screws 23.
  • Another rod 24 extends between the side flanges of bracket 68 above rod 22.
  • a spring. 25 is connected to rod 24 and to a rod 26 supported in flanges on each side of a plate 2'! secured to the machine frame.
  • bracket Hi to be pivoted about rod 22, to move the upper end of the bracket away from the machine, as illustrated by the dot and dash lines in Figure 4.
  • bracket 98 serves no useful purpose in the operation of the front feed bail opening and closing mechanism but is necessary to provide clearance for removing a detachable control plate 32 that supports control magazines 33.
  • Cam member ll lies in the path of a roller 34 ( Figures 4 and 5) rotatable on a screw 35 extending through two clamping plates 36 and 31 and threaded into a thumb nut 38.
  • Clamping plates 36 and 31 embrace two rods 4! extending laterally of the machine, as shown in Figure 2
  • tightening of thumb nut 38 assisted by'a shoulder near the head of screw 35 bearing against clamping plate 36, causes clamping plates 36 and 37 to tighten against rods 4 I to hold the unit against movement along the rods.
  • are secured at each-end to levers 42 ( Figure 2) pivoted on screws 43 at each end of the carriage.
  • One or more clamps 44 are secured to the two rods 4
  • a pitman 45 ( Figures 2 and -7) is pivoted at 46 to the lower end of lever 42 and rests, near its forward end, in a shallow groove in a stud 41 secured in the carriage side wall 4.
  • a tension lever 48 is likewise pivoted to the carriage side wall at 5
  • a spring 53 is connected to the rear .end of lever 48 and to the carriage side wall. The normal position of these parts is illustrated in Figure 7 where roller 34 is in the vertical plane of pivot screws '43.
  • pitman 45 The forward end of pitman 45 is provided with two depending lugs 54 and 55 adapted to co-act with a stud 56 on front feed bail 6.
  • Figure 7 shows that there is sufficient clearance between lugs 54 and 55 to permit the front feed bail to be manually opened or closed, if desired.
  • FIGS. 10 to 12 show a modified form of the invention that is used where it is desired to open the front feed bail automatically but not to close it automatically.
  • pitman 45a is provided with 2.
  • lug 55a but no lug corresponding to lug 54 ( Figure 7). Therefore, movement of roller 34 forward, during the return stroke of the carriage, to the position shown in Figure 11, opens the front feed bail, but movement of roller.34 rearward, during the working stroke of the carriage, to the position shown in Figure 9, will have no effect on the ball.
  • Figure 10 illustrates the roller moved to a positionwhere it is entirely disabled. This is accomplished by the operator manually moving pitman 45a to its extreme rearward position where stud 52 engages a deep notch 6
  • cam I1 would be adjusted to the position shown by the dot and dash lines in Figure 3. When in this position, the cam member moves roller 34 forward during the last increment of travel of the carriage in its working stroke, to open the bail. This is often desirable as it gives the operator an opportunity to change the front fed work sheets during the return movement of the carriage.
