Describing my invention in detail, and with reference to the drawings, designates the base of the mechanism, the base preferably having the form of a rectangular casting comprising a base plate 2, and side, front and rear flanges 3, 4 and 5, respectively, depending therefrom. Suitable resilient supports 6, and sockets 1 therefor, are secured to said base by screws 8 threaded into bosses 9.

Surmounting the base I is a similarly shaped head I, presently'described in detail, pivoted at its front end, as at H, for vertical rocking movement on supports |2 upstanding from the base plate I. The head I is normally held elevated by head operating mechanism, as follows:

Journaled at the rear of base I, in the side flanges 3, is a transverse shaft l3, operatively connected to said head by means of a crank arm |4 thereon, and links |5 connecting said crank arm to a rod l6 secured in lugs H on said head. Shaft I3 and links |5 are urged in a head elevating direction by springs l8 connected to crank arms IS, on said shaft, and to a rod 20 secured to flanges 3. A crank arm 2|, fast on the shaft I3, establishes the normal elevated position of the head II) by engagement with the base plate 2. A hand lever 22 is provided on oneend of the shaft l3 for operating the latter to depress the head ||l in opposition to the springs l8. Depression of the head I0 is limited by engagement of the links I5 with the shaft l3, as shown in dotted lines in Fig. 3.

Intermediate the base I and head Ill is a fleld or set of vertical punches 23, disposed in rows corresponding to line and columnar positions and a pair of auxiliary special designation punches 24 and 25, located in the rear of the punches 23 and intermediate columnar rows thereof, to punch distinctive perforations in the work for indicating cash and credit transactions therein. The .punches 23, 24 and 25 are mounted for independent movement in the usual perforated stripper plate 26 from which they are normally suspended by heads 21 thereon.

Cooperating with the punches 23, 24 and 25 are perforated die and guide plates 28 and 29, respectively, superposed in spaced apart relation, to form therebetween a punching chamber 38, and throughwhich said punches pass in a punching operation. The plate 28 is spaced from the plate 26 by attachment to opposed undercut side bars 3| and 32, which, together with plate 26. are secured to the base plate 2 as by screws 33.

The stripper plate 26 is suspended from the head II for vertical movement thereby, as follows:

At opposite sides of said plate are opposed pairs of angularly related links, including horizontally disposed parallel links 35, pivotally connected to the side bars 3| and 32, and vertically movable by the head l0 through the medium of vertically disposed links 36 pivoted to said head, as at 31.

The stripper plate 26 is supported at its side edges by said links 35, whereby it is elevated to retract said punches from the punching chamber 30. Vertical plungers 38, depending from the stripper plate 26, adjacent each side thereof, and fitted into bores 39 in the side bars 3| and 32, guide said plate in its vertical movement to maintain it in horizontal position. Under normal operation, that is to say in punching operations, the heads 21 of active punches act to depress the stripper plate 26, as will be clear. However, it has been found that the plungers 38 are liable to bind and jam under such action by said punches,.because of the locations of the punches relative to said plungers. Therefore, set screws 40 are provided on the head It), directly above the plungers 38, whereby depressing forces are exerted by said head l0 against the stripper plate 26 in line with said plungers 38, and binding of the latter obviated.

The punches 23, 24 and 25 are recessed, as at 4|, intermediate their ends to form longitudinally spaced shoulders 42 thereon. A perforated punch guiding plate 43 is suitably secured to the side bars 3| and 32. A locking plate 44, provided with transverse slots 45 and intermediate tongues 46, is adjustably secured to the plate 43, as at 46, so that said tongues 46 are positioned in said. recesses in intercepting relation to the shoulders 42 to lock the punches against removal from the machine. The locking plate 44 is adjustable to an ineffective position to unlock said punches, as will be clear.

The punches 23 are selected for operation through the medium of a series of key set toothed selector bars 41, one for each columnar row of punches, and suspended in a recess 48 in said head, as by rails 49, for sliding movement longitudinally of their associated row of punches. The connections between the keys and selector bars are arranged and mounted as follows:

Secured upon the head III, in any suitable manner, are superposed housing members 50 and 5|, forming upper and lower chambers 52 and 53 above said head. A series of laterally spaced slides 54 is mounted in the chamber 52 for movement longitudinally of said rows of punches 23, said slides being provided with keys 55 projecting through slots 56 in the housing member 50 for manual manipulation of th slides. The upper face of the housing member 50 is provided with rows of numbered graduations 51 for indicating the number represented by the punch selection in each colunmar row of the latter, and the slides 54 are likewise graduated and numbered as at 56 to display, through suitable sight openings 59, in the housing 50, the aggregate number representation of the punch selections.

As will be understood, it is desirable that the rows of punches 23 be closely spaced for condensing the punched record, and that the keys 55 be widely spaced, relatively speaking, to facilitate their operation. ,To dispose the selector bars 41 in spaced apart relation, corresponding to that of the columnar rows of punches 23, and for setting by the widely spaced keys 55, the following connections between the slides 54 and said bars are provided: e

Suspended from the slides 54, as by posts 66 passing through slots 6| in housing member 5|, are two opposed series of plates 62 arranged in each series in overlapping stepped relation to overlie related selector bars 41. Vertical legs 63 on the bars 41 connect the latter to appropriate plates 62. Tensioned detent dogs 64, cooperating with notches 65 in the bars 41, yieldingiy latch the latter together with the keys 55 and slides 54 in selected position.

Mounted below the head M, in opposed brackets l secured to said head, is a special punch selector slide or key 66 endwise movable manually over the special designation punches 24 and 25 to select the latter for operation by the head l0,

when the latter is depressed, and having one end extending beyond the head l0 for manipulation of said slide by the operator. Preferably the slide 66 has two positions only, in each of which an edge thereof overlies a punch 24 or 25, as the case may be, and is provided with an edge notch 61 for clearance of the other punch by said slide when said head is depressed. Shoulders 68 on the slide 66 establish the two positions of the latter. A spring pressed detent 69, mounted in the head l0 and cooperatingwith notches in l the slide 66, yieldingly retains the slide in either transactions on the cashiers token and card.

Appropriate legends, such as shown in Fig. 18, are provided on the extending end of the slide 88 for indicating through a sight opening H in a suitably mounted plate 12 whether or not the selection of the punches 24 or 25 is appropriate to the token to be punched.

The work carrier comprises a tray 13 removably mounted on a support 14 for sliding movement between edge guides 15 on the latter, to advance and retract the front end thereof into and from the punching chamber 30, stop member I8 and end rail 11, on the die plate 28 and table I4, respectively, limiting advance and retraction of said tray 13. The front end of the latter is provided with a recess 18 for clearance by the punches in a punching operation, and over which the token 19 or a record card 80, or both, are placed for perforation by said punches. Adjacent the edges of the recess 18 are front and rear work holding members 8| and 82, respectively, suitably secured to the bottom of said tray and forming, together with the latter, a pocket for receiving three corners of the token 19, the fourth corner being left free. An aperture 83 is provided in the bottom of the tray 13 below the free corner of said token, for facilitating removal of the latter by the operator as will be clear. The front work holding members 8|, together with front, rear and end flanges 84, 85 and 11 on said tray, form a pocket for positioning a record card in said tray beneath a token I9, and for aligning the front edges of said card and token as shown in Fig. 11, the rear member 82 being spaced from the bottom of the tray 13 for insertion of said card thereunder and one front member 8| having an undercut keeper lip 81 forholding the front edge of the card against said member.

The work carrier tray I3 is locked in its advanced position and hence the work in punching position by means of the following:

A plunger 88 is mounted in the base plate 2, in the line of movement of one edge of the work carrier tray I3, and for vertical movement in said plate. Normally, the,plunger 88 is elevated, in which position said edge of the tray 13 is movable through a recess 89 in said plunger. When the work carrier tray is fully advanced, a recess 90 in said edge thereof registers with a key 9| extending along said plunger. Operation of the hand lever 22 to depress the head l0 lowers said plunger to enter the key 9| in the recess 90 and look said tray against movement prior to and during the punching operation. The operating connections between the hand lever 22 and plunger 88 comprise a pair of levers 92 and 93 pivotally mounted as at 94 and 95, a pin and slot connection 98 between said levers. and similar connections 91 and 98 between said levers and the crank arm 2| and plunger 88, respectively. The plunger is returned to normal position by the beforementioned spring l8 as will be clear, the key 9| maintaining the tray 13 locked until the punches 23, 24 and 25 have been fully retracted. A receptacle 99 is slidingly mounted below the base plate 2 in supports I00 to receive the punchings from the die plate 28. A leaf spring l0| frictionally engages the bottom of said receptacle to hold the latter against accidental displacement.

By referring to Figs. 13, 14. and 15, it will be seen that the customers and cashiers tokens are of the same size, whereas the clerks token is r l. atively narrower. For punching the latter, and a record card therewith, a work carrier tray I02 (Fig. 10) is provided, in, which the front and rear holding members 8| and 82a form a narrower pocket for said token, and which may be'substituted for the work holder of Figs. 9 and 11, as will be understood. 1 a

A corner of the tray 13, or I92, is beveled, as at I05, and the corresponding corner of the support 14 is similarly beveled, as at I06, so that a corner of a. card 80, located in said tray, will project beyond said tray and support to facilitate removal of the card from the tray by an operator.

A corner of the card 80 is usually beveled as at I01 for a purpose not important to this disclosure. To prevent the operator from inserting such a card in the tray, or trays, in wrong position, a pin I08 is provided on said tray for cooperation with said beveled corner I01, when the card is correctly positioned and which blocks location of said card in wrong position in said tray.

It remains to be stated that the machine is particularly designed for perforating according to the well known Lasker-Woodruff code disclosedin British Patent No. 378,571 of 1929. Suffice it to explain herein that this particular code is based on ten permutations of six punches in each columnar row, as shownin Fig. 14, and that the racks 41 are provided with wide and narrow teeth I03 and I04 arranged to select successive and alternate punches 23, respectively, according to the punch combinations of said code.

The operation of my invention will, it is believed, be understood from the foregoing description of a preferred embodiment thereof.

Obviously, however, changes in form and modifications of details could be made without departure from the inventive concept disclosed, and it is, therefore, to be understood that only such limitations shall be imposed on the appended claims as are required by the prior art.

, What I claim is: v 1. In a card punching machine, the combina tion with a field of punches, and means for selectively operating the same, of a work carrier operable to feed the work to said punches and in eluding work holding members forming superposed pockets of relatively different sizes for holding relatively large and small cards in superposed fixed relation.
