  • This invention relates to printing tabulators and moreparticularly to printmg tabulators which are adapted to print the alphabet as well as the usual numerals.
  • speed of printing is a desideratum and previous machines have been devised in which a rotating drum is employed carrying the type carriers and in which the type carriers were called into action to strike and imprint characters upon paper carried by the platen during the rotation of the drum.
  • a construction of this sort is particularly adaptable for. speed of operation because there is no necessity for an idle resetting movement of the parts due to the continuous forward rotationv of the drum which carries the type carriers.
  • vIt is accordingly, one object of the present invention to provide a construction which is capable of effecting a selection of and the obtaining of printed impressions from multiple character type on type bars while the latter are in motion and during one revolu- ⁇ :)ion of the drum which carries such type are.
  • Figure 1 is a side elevational view shown partly in section and which shows a printing drum having type carriers and type thereon arranged for both numerical and alphabetical printing and provided with the sa lecting devices which are required for selecting the type for printing action.
  • This figure also shows somewhat diagrammatically the related adding mechanism;
  • Fig. 2 is a somewhat enlarged view of a fragment of the drum drawn on a greater scale and showing certain of the parts shown in Fi 1, but with certain of the move position;
  • Fig. 3 is a view somewhat similar to F g. 2, but showing the parts in a still further d18- placed position in which the particular selection of type on the carrier is being efl'ected;
  • Fig. 4 is a diagrammatic view showing a typical record card with its controllmg perforations;
  • Fig. 5 is a front view of one set of type carriers which are disposed in one row around the drum. In the figure, for convenience of illustration, the successive type carriers are disposed side by side; and
  • Fig. 6 is a circuit diagram of the machlne. 'Referring to 'Fig. 1, 20 is the printing parts in drum provided with the type restoring cam shaft 21 and with any suitable driving train for rotating the drum, for example, the driving train 22 shown by the dotted line gears. Disposed in the drum are rows of type carriers 23. These type carriers co-act with the camming shaft 21 in the manner fully described in Carroll Patents No. 1,516,079 and No. 1,726,539 and accordingly, a description of their operation will not be repeatedhere.
  • Magnets 24 are the primary selecting mag-' nets audit is the energization of these magnets u'nder record card control that makes the primary selection and calling of the type carriers'into action. It is suflicient to here state that the energization of magnets 24 trip flatches 25 which in turn are positively actuated by the heels 26 of succeeding type to in turn actuate hook 27 and displace such book- 27 into position for calling a type carrier.23 by swinging action into position to print. (See Fig. 3.) This mechanism is substantially identical with the mechanism of Carroll Patent No. 1,726,539. In Fi s. 1 and- 2, 28 is the platen carrying usual s eat of aper .29.
  • each type carrier 23 is provided with a multiplicity of type characters, i. e. 30, 31, 32 and 33,'Fig. 3, and such type characters are mounted so as to be relatively movable with respect to the carrier 23, Fig. 3 shows one construction in which the various type characters 30 to 33 inclusive, are secured upon a type carrying element 34- which is relatively slidable on its cooperating carrier 23.
  • the aggregate number of type on all of the carriers is greater than the complete number of the carriers themselves. For example in the embodiment shown there are four times as many type as there are carriers for the type.
  • a camming element 35 preferably pivoted upon a shaft 35a and having a camming face 36 disposed to contact with the curved end of the type element 34.
  • a cam 37 which rotates synchronously with the rotation of the drum and which cam displaces a follower 38 and through a linkage magnet 45 which magnet, accor ing to its time of energization, trips a latch 46 and trips a pawl .47, causing. 1t to engage one of the steps 42, 43 or 44 or to miss the 44 step entirely.
  • the above secondary selecting mechanism provision is made for selecting which of the type 30, 31, 32 or 33 will impact against the platen and this selecting action is effected during one revolution of the printing drum so that any one of the greater number of type upon a carrier can be caused to print during such single revolution of the drum.
  • This selecting action is effected during one revolution of the printing drum so that any one of the greater number of type upon a carrier can be caused to print during such single revolution of the drum.
  • the piloting part 35 receives a preliminar 'set up, the actual selecting action occurs w ile the type carrier brushes and contact blocks 54, 55.
  • Theusual card picker devices are employed which are well known in devices of this sort and in addition the apparatus is driven by a suitable driving motor M.
  • the spacing relation of lower brushes 52 with respect to upper brushes 54 is such that the upper row of rushes will have left any holes in the 12th index pointv position in the card (see Fig. 4) atthe time when the lower brushes 52 are about to encounter the 9th index point position on the card.
  • Suitable cam contact devices 56 and 57 are provided to supply current to the brushes 52 at the proper time and to brushes-54 and the circuits therefor.
  • Contact blocks 55 lead to a plugboard 58 having plug sockets which connect to the selector magnets 45 as shown.
  • Contact blocks 53 lead to a plugboard 60 having multiple sockets as shown and the primary selector magnets 24 are shown as connected to plug sockets 61.
  • 62 represent the counter magnets (see Figs. 1 and 6) and suitable sockets 63 are provided for these counter magnets.
  • each of the latches-46 associated with the selector mag-' nets has cooperating therewith (see Fig. 3) a contact each of which contacts has one blade connected to a plug socket 71 and another blade connected by suitable conductors to plug sockets 63a.
  • plug connections are made in the desired columns between sockets 58 to place in circuit the sup plementary selector magnets 45 and in addition, connections are made between plug sockets 60 and 61.
  • the timing of the machine is such that upon the passage of a card past both sets of brushes, the secondary selection is made first by the brushes 54 encounterin the holes in either the zero, 11th or 12th in ex point positions. v Thereafter the primary selection is made by the holes in the 9 to 1 index point positions in the usual manner.
  • the ener-' gization of the primary selector printing magnets 24 calls a selected carrier for printing action and during the movement of the carrier and while it is swinging towards the imprint position, its secondary selector havof type by aprimary and secondary selection action, which primary and second selection is made during one revolution 0 the printing drum, that it is possible to effect adding during one revolution of the drum and that in the same single revolution of the drum it is possible to select or print all of the letters of the alphabet and the numerals Accordingly, a record controlled machlne can print alphabetical characters'and concurrently add at the speed heretofore only obtainable for adding and printing numerlcal characters alone.
  • the printin "of the alphabet does not hamper t e spee of adding.
  • the present construction provides a tal iulating machine in which one speed of operation of the printin mechanism can be used for both listing, a ding and listing, adding alone, or adding with accompanym alphabetical printing.
  • a phabetical printing was attem ted the speed of machine operation as a w ole was hampered orthe drum proportions were so increased that adding took place in one portion of the printing cycle followed by' subsequent alphabetical printing.
  • a printing mechanism comprising a number of continuously movable type carriers each with a plurality of type thereon which are relatively movable with respect to the type carrier, and means for concurrently selecting a. type carrier and a particular type upon a carrier for printing action.
  • a printing mechanism for a record controlled machine in which a type carrying drum is provided carryin a plurality of type carriers each with a plura ity of type thereon and in which a sensing means is provided and including in combination mea'ns for sensing one record for each revolution of the printing drum, means for effecting a concurrent major and minor selection of the type durin one revolution of the drum.
  • g printing mechanism having a drum, type carriers thereon, type on said carriers which in the aggregate are greater in number than the number of the carriers, and means for individually calling any one type into printing action during any single revolution of the drum.
  • a contmuously movable printing means operative to make one complete cycle of movement for each record handled and read, type carriers upon said means and type upon the said carriers which in the aggregate are greater in number than the number of carriers and than the index points upon a single record, and means for selecting any single type representing an individual character for printing for each record handled and during one revolution of the drum.
  • means for analyzing a perforated record card comprising prlmary and secondary sensin means, a plurality of type carriers each witli multiple type thereon; means controlled by said primary sensing means for selecting a type carrier for printing action, means controlled by said secondary sensing means for controlling which of the type upon a carrier is to be caused to print and further means controlled ,by said secondary sensing means for controlling the operation of said primary sensin means.
  • a machine of the class described having a plurality of type carriers each with multiple type slidably mounted thereon, means for rotating said carriers whereby centrifugal action will cause relative displacement of the type upon a carrier, means for selecting a carrier for printing action and means for controlling the centrifugal movement of said type to select a particular type upon the selected carrier for printing.
