PATENT OFFICE ASSIGNOR TO THE TABULATIITG MACHINE COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY PUNCHIN G DEVICE Application filed July 5, 1923. Serial No. 649,415.

In the use of tabulating machines, occasions arise where it is desirable that groups of cards be punched in certain fields consecutively. Also it may be desirable to have all cards of a group perforated alike in certain fields. With previous punching devices it has been possible to gang punch the like perforations, but for perforating the various cards with perforations designating consecutive numbers where different perforations are required for each card of a series, it has been the practice to effect such perforations by hand punching. Such operation is not only expensive where long runs of consecutive number designating perforations are reuired but there is usually the necessity of c coking the individual cards to determine the accuracy of the punching.

The present invention contemplates the use of a simple consecutive number punching. ap-

" paratus which may, if desired, be applied to a press of the type usually used for printing tabulating cards. This apparatus when applied to a ress will effect the desired consecutive punc ing of cards at the time they are being printed, and if desired the apparatus may be used separately from the press. The apparatus further provides for the perforation of like perforationsin certain fields of all the cards of one consecutive number group. Suitable means is provided for changing the fixed nforations from time to time as desired. eans is also provided for resettin the consecutive number controlling devices y hand to any desired initial setting and for indicating to the operator the number which is then being perforated by the machine. a In the drawin i Fig. 1 is a sida view of--my attachment.

Fig. 9 is an enlarged view of certain of the parts shown in Fig. 2, with the punches displaced through the card stock.

Fig. 10 is a view of one of the cards punched by the machine and after printing thereof.

In more detail, the card printing press which is of the usual type and herein not illustrated, is provided with side rails 10 upon which the punch structure as a whole The supports for the structure include a bottom plate 11, and a top plate 12 suitably connected and having a die plate 13 fast to the bottom plate. The die plate is spaced slightly from the top plate to provide clearance for the passage of a strip of card stock 14 therethrough (see Fig. 8). p

' uitably carried by the top plate 12 are brackets 15 (Fig. 1) which are providedwith upper and lower cross shafts 16 and 17. The

superstructure of the punch is providedwith side plates 18 which are slotted to receive the cross shafts 1617 so as to permit vertical displacement of the superstructure relative to the punch bed parts. 7

' In order to provide for peforations in selected fields the punch bed is adjustable longitudinally of the guides by means of a rack and pinion 20-21. The rack as shown m Fig. 2 is fast to the lower plate, whereas the inion is secured to a suitable shaft journaled 1n one of the side rails and provided with a setting knob 22 best shown in Figs. 1 and 8.

The punches 23 are guided in openings in the upper plate 12 and'in a plate 24 which is suitably supported by the upper plate in v the manner shown in Fig. 2. The individual punches are provided with collars 25 at their upper ends and below these collars are restoring bars 26 which extend across andconnect to the side plates of the punch superstructure.

Pivotally mounted on shafts 27, which are supported by the plates 18, are punch selector levers 28. These levers are arranged in groups and are of different length. The group marked 280 are the unit group and cooperate individually with the right hand or unit column; those marked 281) are the tens group and cooperate with the second or tens row of punches. V

The individual selector bars of a group are provided with lugs 29 which project upward- 1y from each selector bar. Disposed above ing selecting pins 31 disposed spirally thereon as shown in Fig. 3. It will be understood that if the selector shafts are rotated step by step the various pins 31 will successively align with the various lugs 29 representing different amounts. Thereafter if the side plates 18 are lowered the selected pin 31 will act as a stop for the selector bar and cause the latter to advance a selected punch through the paper.

In order to effect the displacement of the side plates 18 for punching, the upper shafts 16 are provided with eccentrics 33, the straps 34 of which connect to the side plates 18 as shown in Figs. 2 and 3. Shafts 16 are rocked by a linkage 3536 which in turn is positively the press actuating mechanism.

To depress the plates 18 the shafts 16 are rocked counterclockwise. Upon the reverse movement of these shafts the advanced punches are retracted by the bars 26. At the same time the unit column selector shaft is advanced one step by a pawl lever 37 (Fig. 5) which is suitably connected with the main actuating linkage 3536. The pawl lever actuates a ratchet 38 which through gearing 39 advances the units selector shaft. Intermediate the various denominational order selector shafts are suitable transfer devices here shown as comprising the well known Geneva stop transfer device indicated generally at 40.

For resetting the selector shafts 30 to zero and for setting up any desired number thereon, I provide setting knobs 41 on each shaft. Suitable indicating dials 42 are also fixed to each shaft to show the setting of the number shafts at any time. In order to reset the selector shafts individually provision must be made for disengaging the transfer mechanism. This is accomplished by means of a supplementary knob 44 which may be displaced to rock a shaft 45 and thereby disengage the slidably mounted intermediate gears 46 of the transfer devices. To provide for proper aligning of the selector shafts so that the transfer gears may be readily reengaged I provide aligning star-wheels 47 on each selector shaft. These star-Wheels are engaged by resiliently actuated dogs or pawls 50. Y

The operationof the selector shafts 30 actuated in any desired manner from,

in proper turn transfers to the next higher order shaft, and, so on.

In order to gang punch predetermined set ups in certain card fields, supplementary Lpunches are provided shown to the left of t e various lugs are selector shafts 30 hav- Such slug is provided with suitable drilled openings to receive one or more lugs 51 which overlie the punches which are to be operated at each operation of the mechanism. The slugs are slidably inserted in slots in the side 'wall 18 of the punch superstructure. While 7 only one slug is illustrated, it will be understood that any number may be emfiplo ed, depending upon the number of card el sin which gang punching is desired.

It will be understood. that the counter selecting devices and the actuating mechanism therefor may be arranged to count forward or reversely; i. e. from 1 to 10,000 for example or from 10,000 to 1. The latter arrangement is desirable with certain classes of work and with certain types of card stackers and where the cards as stacked are to be directly used in a tabulating machine'without reversing the order thereof.

What I claim is 1. A punching device oomprisin a lurality of groups of punches adapted to esignate numerical data by the location of punched holes in a field of a record sheet, means for setting and operating said punches consecutively to perforate consecutive number designating punchings on adjacent index point columns of record sheets, upon successive operations, and means for shifting said punches transversely relative to the record sheet material whereby the punching may be effected in different fields thereon.

2. In a punching attachment including in combination, a plurality of punches, selector mechanism therefor, operating mechanism for said punches and selector mechanism including separate selectors for the punches of various denominational orders, means for operating one selector from another, and manually manipulative means for resettingthe selectors to zero.

3. A punching attachment forrecord sheet material comprising a plurality of punches, means including selective devices for operating said punches to successively perforate consecutive number designations upon the record sheet material upon successive operations of the attachment, and means for setting the selector mechanisms for the initial punching of any'desired number.

A punching attachment for record sheet material comprising a plurality of punches, 6 means including selective devices for operating said punches to successively perforate consecutive number designations upon the record sheet material upon successive operations of the attachment, means for manually 10 adjusting the selecting mechanism to various positions, and means for indicating the positions in which the selecting mechanism is set. a 5. A punching attachment for record sheet material comprising a plurality of punches,

means including selective devices for operating said punches to successively perforate consecutive number designations upon the record sheet material upon successive operations of the attachment, the aforesaid selective device including a plurality of devices of different denominational orders, transfer mechanism intermediate said devices, and means for manually setting one or more of said selective devices, said means including provisions for initially disengaging the transfer devices for the purpose described.

6. A punching device comprising a plurality of punches, means for selecting the punches, mechanism for effecting operation of the selected punches including means for automatically causing said selecting means to successively select punches corresponding to consecutive character designations, and pivoted interposer members between the selecting means and the punches for causing the punches to operate in accordance with their selection.

In testimony whereof I hereto afiix my sig- 40 nature.
