FORD, F SCARSDALE, NEW YORK, ASSIGNOR T0 THE TABULATING MACHINE COMPANY, 0F ENDICOTT, NEW YORK, .A CORPORATION 0F NEW JERSEY PERFOEATING MACHINE /L Application led Ian-nary 25, 1929. Serial No. 334,882.

This invention relates to card perforating machines and more particularly to the type adapted to eii'ect copies of perforated record sheets or cards.

It has been proposed, heretofore, to provide certain types of accounting machines such as cash registers with a perforating mechanism to perforate a record tape at the time of making a sale. The tape is perforated with characters representing different classification transactions and the amount of such sales. The perforated tape is then passed through the auditing machines to obtain `the totals corresponding to the dierent classification transactions and the tape is passed through the machine once for each segregation desired.

However, it is not possible to obtain totals of sales related to certain ones of a group identifiedfby the same classication characters and this lack of flexibilityL and other objectionable features militates against the eX- tensive use of such systems. As is generally understood, where the entries are represented by perforated record cards considerable ilexibility is possible, since it is a simple matter to sort cards according to any desired classification to subsequentlycontrol accounting machines.- Aside from the flexibility derived, record cards may contain considerable moredata than represented by a perforated` ta e and are of a form convenientto handle, le and operate with. v

Itis then the Vmain object of the present invention to prepare in duplicate a record card for each section of a record tape representing a classified entry.

It is a further object of the invention to reject or segregate the cards which are prepared in duplicate from a section of the tape erroneously or improperly perforated, such segregation being controlled eithenautomatically or manually.

Other objects of the present invention will be clearly apparent from the following specification, claims and drawings which disclose la preferred embodiment of the invention.

Fig. 11 is a plan view of a section of the perforated record strip.

Power fordriving the various mechanisms is provided by any suitable motor drivin the belt pulley 2O (Fig. 1) rotatable with a rive shaft 21 secured to which is a pinion 22 meshing with a gear 23. The Elatter is secured to shaft 24 which drives a gear 25 through a pair of friction clutch elements 26, the elementrotatable with gear 25 being loosely mounted on shaft 24. As best shown in Fig. 5 the` perforated record strip 27 is drawn from a supply roll 28 and is unrolled therefrom by a feeding roller 29 having peripheral projections engaging the usual marginal perforations.

The strip as it leaves roller 29 is presented l to an analyzing mechanism A and is subsequently fed by a supplemental roller 30 similar to roller 29. The roller 30 is driven by a gear 31 meshing with gear 25 (see Figs. 1 and 10) while the roller 29 is driven by gear 31 through a gear train (Fig. 4) comprising one to one ratio gears 32, 33, 34, 35, 36 and 37. After leaving roller 30 the strip is rolled about a storage roller 38, the supporting spindle 39 (Fig. 1) Abeing driven by a drive pinion 41 through a pair of friction clutchlemei s 42 secured to shaft 24.

Secured to shaft 21 is a worm 43 (Figs. 1 and 4) meshing with a worm wheel 44 secured to a cam shaft 45 which carries a paper feed controlling cam 46. Suitable means now to be described is provided to control the intermittent paper feeding operations. Rotatable with the gear 34 (Fig. 4) is a shouldered disk 47 the shoulder of which is in the plane of the hooked end of a bell crank member 48. The cam 46 (Fig. 2) cooperates with a follower of an arm 49 which imparts motion to the bell crank member 48 through a coil spring 50. In the position shown '(Flg. 2) the low point of cam y46 has permitted a spring 5l to rock arm 49 downwardly to raise the hooked end of bell crank member 48 out of engagement with the shoulder of disk 47 to render the paper feeding mechanism operative.

Clutch elements 26 and 40 are now effective to feed the perforated strip and when a certain amount has been fed the high point of cam 46 will rock bell crank- 48 reversely so that the hooked end reengages the shoulder of disk 47 to stop the paper feed. During paper feeding operations a record card is fed to the punching mechanism in order that the selected punches may perforate the vcard in accordance with the perforations in the strip. Any suitable picker mechanism may be provided to feed the cards singly from a hopper and may comprise that shown in the gatent to C. D. Lake, No. 1,600,413 dated eptember 21, 1926.

The arm 52 (Fig. 2) which reciprocates a picker knife 53 to effect card feed may have any vsuitable driving connections to the operating mechanism. Each card 57 as fed is presented to pairs of feeding rollers 54 and 55 (Fig. 1). Both pairs are driven by a worm 56 secured to shaft 21. When a card 57 is fed tothe desired position beneath the punches it is held against further feeding movement by a card gate comprising a card abutment plate 58 (Figs. 2, 6 and 7) suitably guided for vertical movement. A pair of levers 59 secured to a tube 61 and connected to the plate 58 by links 60 are adapted to be detail, air pressure is supplied to an entrance pipe 65 (Fig. 2) which leads to the air entrance 66 of a valve 67 and which has an air communication to the exit 68 when a piston 69 is raised. The piston rod 69 is connected to a plate 70 apertured to receive an eccentrically mounted disk 71 secured to shaft 45. Elevation of the piston at the desired time permits compressed air to flow through perforations 661, through the cylinder and perforations 681 to the exit portion 68 to a connecting pipe 72 which communicates with a pocket 73 of a cap 74. The cap 74 at its lower face has several'series of perforations in registration with a similar number of perforations in a plate 75 spaced apart from the cap to permit the perforated record strip to pass therebetween.

When the piston is lowered the cylinder is opened at its upper end to the atmosphere through -a screen 682 relieving the-air pressure on the record strip. When a perforation of the stationary strip is in registration with an aperture in cap 74 and plate 75 (Figs. 6 and 7) air pressure will flow through a duct 76 to actuate a related spring urged plunger 77. Each plunger when depressed actuates a spring pressed stop rod 78 `having a shoulder 79 adapted to engage under a pin 80 of a latch plate 81 to thus lock the actuated stop in depressed position (see Fig. 7). The card when fed is interposed between a die plate 82 and a guide block 83 in which the punches 84 are slidably mounted. The die plate and guide block are spaced apart but move as a unit upwardly to effect punching and when both are in their normal lowered position (see Fig. 8) the heads 85 of the punches 84 rest upon a stationary guide plate 86 to avoid interference with the punches by a card in its transitory feeding movement. When a stop 78 is depressed the lower portion thereof contacts the head of the related punch 84 (see Fig. 8) so that when both the guide block and die are elevated the locked stop 78 will act to indirectly force the punch 84 through the card to perforate it, as clearly relieve pins 8O of any strain during the punching operation aslide 87 is positioned so that integral portions move into an interlockinor relationship with one of two slots 88', 89 of tlie stops 78, depending whether a stop is depressed or not, thereby locking all the normally positioned or depressed stops. IMovement of the locking plate 87 to accomplish the above is provided by a bail 90 looselymoun'ted on a stud shaft 91 and having a suitable connection (similar to arm 62; see Fig. 2) to an arm 93 (Fig. 3) actuated by its related operating cam 94. The latch plate is moved by a bail 97 (Fig. 8) which .has a similar connection to its related operating arm 95 (Fig. 3) which, in turn', is actuated by its related cam 96. When the latch plate 81 is shifted it will release those stops 78 which havebeen locked in depressed position.

The preferred means for elevating the` guide block and die plate com-prises a pair ofv cams 97 (Figs. 2 and 5) acting upon rollers 98 carried by the die plate 82. For the purpose ofA driving the cams 97 the cam shaft 99 carries a worm wheel 100 in mesh with a worm 101 secured to shaft 21. Guide block 83 and die plate 82 are restored by s rings 102 (Figf 5) previously compressed uring kthe punching operation.

After the punching operation has been completed the card abutment 58 is elevated permitting sets of driven rollers 103 and 104 to feed the card between guidey plates 105 (Fig. 2). The punched card in its feeding movement strikes a d eector plate 106 which guides it to the receiving hopper 107. The cycle of operation is thereafter repeated effecting a punched card which is a duplicate of the sections of the perforated strip.

It sometimes happens that the perforated strip is improperly perforated and since a card will nevertheless be prepared it is desirable to reject such cards in order to render it unnecessary for the operatorY to manually select such cards from the group of punched cards. The sections of the record strip which are improperly perforated may be marked Void 0r bear some similar identifying marking. When such as section appears the operator may depress a suitable button to close a set of contacts 108 '(see Fig. 9) to energize a magnet 109. The defiector plate 106 is secured to a bar 110 which is pivoted by a rod 111 at its ends so that at the vnormal position of bar (Fig. 2) the deflector will guide the card to the receiving hopper 107.

Associated with the reject station R is an angular delector plate 112 and a guide plate 11.3 both carried by a fixed block 114. A link 118 at one end is connected to an arm 116 secured to rod 111 and at its other to an arm 117 loose on a rod 115. Extending upwardly and securedto the rod isan arm 119 which is normally latched by the armature 120 of magnet 109 (see Fig. 1) and when this latching relationship exists deflector 106 (see Fig. 2) guides the cards to the hopper 107. Upon energization of the magnet 109 a spring 121 is effective to shift the delector plate 106 to the position shown in Fig. 9 lowering it so that the card-is fed by rollers 104 over a horizontal plate which is beneath the plate 113. A pair of feeding rollers 124 (Fig. 2) then convey the card until it strikes the deflector plate 112 which guides the cards to the reject station R; Arm 119 is shifted to be relatched by the armature 120'by a cam 122 secured to drive shaft45.

While the control of the card rejecting mechanism may be manually effected it is pereferable to control it automatically and in the preferred embodiment the presence of a special card reject perforation 125 (Fig. 11) effects the rejection of the card. It will be observed that this perforation is outside of the field of data representing perforations to permit fluid pressure to flow in a tube 126 connected to a piston device 127 (Fig. 9) the piston rod of which is adapted to close the contacts 108 and automatically effect the rejection of the card in the manner just explained.
