PUNCHING DEVICE Filed Aug. 19, 1924 I i 11 Sheets-Sheet 11 Patented June 10, 1930 UNITED STATES PATENT OFFICE JOHN '1'. SOHAAIT, OF WASHINGTON, DISTRICT OF COLUMBIA, ASSIGNOR TO THE TABU- LATIN G MACHINE COMPANY, 01 NEW YORK, N. Y., A CORPORATION OF NEW JERSEY rtmcxme DEVICE Application filed August 19, 1924. Serial No. 732,938.

The present invention'is directed to the provision of an improved machine for performing so-called gang punching operations upon tabulating cards.

I Gang punches as heretofore constructed for such purposes have either had a limited range I being only able to handle a limited field upon the cards or they have been extremely com-.

plicated and expensive and slow in operation.

The present invention is'directed to the provision of a simplified form of gang unch in which the setting of the punches or simultaneously gang punching is derived from a pattern card instead of utilizing individual settin levers or a set-up mechanism controlle by keys, as heretofore. The pattern card may be previously punched in any way and in any selected fields in which gan punching of a number of cards is desire Thereafter the pattern card may be placed in the machine and a card reading pin box adjusted to allow pins to pass through the per-- forated index points in the pattern card. The pins in turn serve as stops for punch selecting devices preferably in the form of interposer bars which may be simultaneously set into cooperation with the pins. The interposer bars in turn select the punches for operation. Provision is made for automatically effecting the gang punching of any desired number of cards as selected by the operator. After the particular run of cards have been punched the machine is automatically sto ped whereupon the operator may remove t e attern card, replace it with another and t en set the machine for gang punching another run of cards.

A further object of the present invention resides in the provision of means for permitting a direct numerical reading to be taken of the setting of the punch selecting mechanism. This obviates the necessity of checking the first punched card produced by the machine.

A furtherobject of the present invention resides in the provision of a simple controlling device for a machine of this class which will permit the machine to be preset to punch any desired number of cards and then to automatically interrupt the operation of the machine.

A further object of the present invention resides in the provision of certain controlling devices for automatically suspending theoperation of the machine upon abnormal operations of certain parts thereof. Provision is made for automatically suspending the operation upon the exhausting of cards from the supply magazine. Provision is also made for automatically suspending the operation of the machine upon the failure of the card feeding devices to operate in a proper manner.

A further object of the present invention resides in the provision of an improved card feed for machines of this class. Suitable provision is made for stopping the card feed ing devices from operation upon the running out of cards from the supply magazine.

Further objects of the present invention will be hereinafter pointed out in the accompanying specification and claims and shown in the drawings which byway of illustration show a preferred embodiment of the invention andmeans for operating the punch mechanism.

The first step in the operation of this machine is to place a pattern card having the data which is desired to be duplicated punched therein, in the machine. Before the card can he placed in position the card sensing means must he lifted up. The card sex-sing means comprises a box-like frame 30, which frame is \."crtically guided at the corner: by posts 31 (see Figs. 2 and 3). Fast to fhe hon-like frame are racks 32 which mesh with pinions fixed to a shaft provided with a crank By rotating the crank the box can be elevated to the position shown in Fig. 10. The box when in this position is retained elevated by means of a pivoted dog 35 which engages a in 36 upon the cran arm. A pattern card P with suitable perforations therein is then placed under the sensing box. The card is abutted against stop posts 38 so that theperforations in the card properly align with the openings of a perforated plate 39 upon which the card is supported.

The means for sensing the perforations in the card comprise a plurality of shouldered ins 40. These fit loosely in guiding perforations in the lower intermediate plates of the box-like frame 30 and upon the frame being lowered, such of the pins 40 as find perforations thereunder pass through the perforations in the pattern card and drop downwardly with their lower ends below the lower face of plate 39. This condition of parts is shown in Fig. 9. It will be understood that with tabula'ting cards only one perforation is usually placed in a column. Consequently, only one pin in each column will project through the card. In some instances there may be dual perforations in the column, in which case two pins will project through. iVith two pins projecting a special arrangement of the devices cooperating with the pins is required as will be hereinafter described. It will be seen that by lowering the sensing pin box which may be effected by releasing latch 35 and either permitting the pin box to descend by gravity or lowering it by the crank, that a set-up of the perforated pattern card will be made on the pins 40. This setup is utilized to control the positioning of interposer bars which in turn control the selection of the punches. Fig. 9 shows one of the interposer bars 41 for one of the columns of pins 40. This interposer bar 41 is in the form of a long bar having a shoulder 42 thereon and a projecting block or abutment 43 and rack teeth 44. Each of the interposer bars is identical, one being provided for each column of pins on the card, as clearly shown on Fig. 2 of the drawings.

Setting device for the i'nterposer bars the interposer bars are shifted to contactwith' the respective pins. Figs. 3 and 10 show the normally starting position of the intcrposer bars and Fig. 9 shows the bars shifted toward the left. In order to effect the setting of the interposers a crank is provided at the side of the machine, which crank is fast to a shaft 46. This shaft is slotted, as shown at 47 (Fi .5) to receive friction washers 48, which was ers are correspondingly splined to fit in the groove of theshaft. Disposed intermediate the various friction'washers are pinions 49, which pinions mesh with the rack teeth 44 of the respective interposer bars. At one end of the shaft 46 there is provided a spring 50 which serves to crowd the friction washers '48 into contact with the adjacent pinions. In order to adjust the amount of friction suitable adjusting nuts 51 are threaded upon the end of the shaft 46. By rotatingthe crank in an anticlockwise direction the various interposer bars 41 will be shifted until their shoulders 42 engage the projecting pins 40 in their respective columns. Thereafter the pinion of the arrested interposer bar Will slip relatively to its adjacent friction washer. In this manner it is possible to differentially set the various interposer bars by a simultaneous single crank movement.

In order to visually display the set-up of the machine after the interposer bars have been shifted the cover plates 52 over the interposer bars is slotted, as shown at 53. Along one side of this slotted opening there are graduations corresponding to the number of columns on the card and the corresponding interposer bars. This index is indicated at 54 in Fig. 2. In order to coordinate the numbers with the card form suitable clips 55 are provided on the cover plate 52 to receive a narrow section 56 cut from the top of one of the cards which contains the designating data. The top surfaces of the interposer bars are also provided with indicating-numerals 57. After the interposer bars have been set their setting appears through the slot 53, as clearly shown in Fig. 2. This permits the taking of a direct reading of the interposer bar setting after the same has been shifted by the crank.

In the event that any interposer bar encounters no projecting pin it will move to its limit of movement being finally arrested by shoulder 42 coming in contact with cross bar 58 (Fig. 9). lVith this position of the interposer bar its block or lug 43 will be disposed out of alignment with all of the punches.

Provision is made for duplicating any desired number of cards up to 1500. In order to set the machine so that punching operations will be automatically stopped when the desired number of cards have been punched the operator adjusts units dial 70 with reference to the zero gauge 71 (see Fig. 1) and if hundreds of cards are to be perforated adustment is also made of the hundreds setting handle 72. Handle 72 is adjusted until index 73 comes opposite the desired number on the graduated scale 74. The adjustment of the units dial is effected by means of the setting knob 7 5. The operation of the stopping devices will be hereinafter described. It will u be assumed that they-are setatthe desired points and that the operator has placed a supply of blank cards in the supply magazine 77 placing on top of them a suitable weighted follower block 78 (Fig.3). a

The operator now'depresses the start key 79 (Figs. 1 and 21) thereby closing contacts 80 and establishing a circuit from source 81 through the driving'motor 82-and back to source. Latch 83 now holds contacts 80 closed and the motor is set in operation.

Motor drive has fast to it a pinion 88 which meshes in turn with pinion 89. A gear train marked 90 in Fig. 19 is adapted to drive delivery roll shafts 91. The pinion 88 is fixed to the main driving shaft 92 of the machine. 7

Referring now to Fig. 3, the .main drive shaft 92 is provided with a crank 93 which has connected to it a pitman 94. The opposite end of the pitman 94 is pivotally connected to an arm (Figs. 3 and 20) which is v loosely mounted ona shaft 96. Arm 95 is at its upper end is provided with a V-shaped jaw 97 which is adapted to receive a cross shaft 98 which in turn is rigidly secured to a pair of picker actuating arms 99. These picker arms 99 are also fixedly mounted on shaft 96. Fig. 16 shows the picker arms 99 together with arm 95. Upon the forward movement of arm 95 to the right in Fig. 3, the picker arms 99 follow operating in a clockwise direction under the influence of coil operating springs 100 (Fig. 16). Pivotally connected to the upper end of the icker arms 99 are supplementary arms 101 Figs. 3, 16 and 23), which at their opposite ends connect to slide blocks 102 suitably mounted for slidable movement in guide slots 103 in the frame parts of the machine. Pivotally secured to the blocks 102 are picker plates or arms 104 carrying a transverse ad usting plate 105.

The adjustment plate is yieldingly pressed upwardly to carry the picker 104 towards the cards by means of a spring 106 and the adjustment of the pickers may be effected by means of an adjusting screw 107. Upon the sition the card C has been passed into the die plates of the punch mechanism. During transit from the supply magazine the cards Die plate structure The die structure includes die plates 61 and stripper plates 62 (see Figs. 9, 22 and 22*). These plates are both fixed to side plates 60, which side plates are guided at their ends by the corner posts 31 and at their outer sides by the side plates 59 of the punch section of the machine (see Figs. 9, 22 and 22 The die plates and the stripper plates 61 and 62 are suitably spaced by spacing plates 61' to provide a throat for the card to enter therebetween. Disposed across the side plates 59 and fixed thereto is a cross plate 64 which is suitably perforated to receive the punches 65 which fit at the lower ends in the perforations in the stripper plate. The punches 65 at their upper ends are provided with heads 65. Slidably fitting in the fixed plate 64 are plunger pins 67. These pins have around them compression springs 68 which bear upon the die and stripper plate assembly and tend at all times to force the'same downwardly. Disposed across the top of the stripper plate 62 are a plurality of bars 63 which are fixed to the stripper plate in a manner not shown. These bars are arranged to fit cooperating notched recesses in the punches 65.

Punch operation It may be stated that just before a blank card C reaches its forward position in the die plate assembly a card abutment 117 is positioned in trontof the die plateto register the card accurately with the die. This card abutment 117 is pivoted .at 118 (Figs. 3 and 4) and is spring thrust by spring 119 into arresting position. The timing of the card abutment operationis controlled by a cam 120 fixed on the main shaft 92 of the machine. This cam cooperates with a follower arm 121 integral with the card abutment 117. After the perforating operation the abutment 117 is withdrawn by means of cam 120.

It will be assumed that the interposer bars 41 have been selectively positioned to bring the lugs over the corresponding punch. The rotation of the main drive shaft 92 causes cams 115 (Figs. 9, 22 and 22) to come in contact with the transverse rod 116 fixed to the punch frame plates 60. The rotation of cam 115 causes the die and stripper assembly to be elevated against the tension of springs 68. Such of the punches 65 as are under the interposing abutments 43 are held downwardly punching holes at the proper positions on the card. This is the condition of parts shown in Fig. 22. All of the punches which do not have interposing abutments over them are lifted up relatively to fixed. plate 64 in the manner shown in Fig. 22". Cams 115 now which is continue in their rotation and at a later time in the cycle the springs 68 come into action to press t e die and stripper plate assembly downwardly and during this operation the heads 65 on the depressed punches act to withdraw the depressed punches from the card. At the same time such punches as have not been depressed are pulled down relatively to fixed plate 64 by means of the cross bars 63. Fig. 22 shows the parts after the punches have been restored. Here cam 115 is shown in the lower position.- The card now in ,the punching die has received a duplicate of the punchings on the pattern card. Means are provided for removing the punched card from the die plate structure in order to ermit the entrance of the succeeding unpunc ed card. -This mechanism will now be de scribed.

Briefl stated, the operation of discharging a card rom the die plate assembly consists in pushing the same from the entrance end of the card throat bymeans of a supplementary device or pusher. This pusher advances the card so that its leading edge enlatter rolls are driven by the feed roll shafts 91 previously described. The feed rolls 122 deliver the punched card to the discharge stack 123. The pusher structure for eflecting this operation will now be described.

Disposed across the machine is a pusher plate 124. This pusher plate 124 is fixed to a cross bar 125 (see Figs. 3 and 2). The crom bar in turn is fixed at its ends to bars 126 which are slidably guided upon the card magazine as shown in Fig. 1. During the forward feed of the blank card by the picker structure the pusher plate 124 is slightly elevated outof the path of the card to permit the new blank card to pass freely thereunder. This position of parts is shown in Fig. 13. The elevation of the pusher plate 124 is effeeted by means of a camming projection 127 on bars 126. When the bars 126 are restored to the left the camming projection rides up on rollers 128 and thus elevates the pusher plate. In order to actuate the usher plate a pair of links 129 are provi ed, each of ivotally connected to operating arms 130 Figs. 24 and 25). The links 129 are also upwardly slotted at 131 (Figs. 1, 11 and 12) to receive studs 132 fixed to the bars 126. To maintain the engagement of these slotted portions of members 129 with studs 132 springs 133 are provided removably secured to brackets fast to the bars 126 and at the lower ends to links 129. The spring support and open top slot construction permits the disconnection of the pusher plates from the actuating mechanism at any time should it be desired to retract the pusher plate manually if it is desired to remove a mutilatai card or for any other reason.

The arms 130 are operated at the proper time in the machine cycle by means of coil thrust to the rightby means of a pin 143 caroperating springs 181 (Fig. 25). Referring ried on one of the cams 115. a

to Figs. 11 and 12 there is suitably fixed upon the main driving shaft 92 of the machine the cam 182, which cam cooperates with a pair'of arms .183, 184, provided with suitable follower rollers adapted to engage the cam. Arm 183 is fixed to the shaft 185, to

which the pusher actuating arms 130 are also fixed. Arm 184, on the other hand, is loosely mounted on shaft 185. In the normal operation of the machine the follower roller on arm 183 follows cam 182 and permits the spring actuation of the pusher arms 130 at the proper time in the machine cycle. Should the pusher devices j am in their forward movement due to a mutilated card or for any other reason the arm 183 will not follow the cam but will assume the position shown in Fig. 12. Arm 184 is rovided with a shoulder 186 extending un er a spring contact blade 187 forming one of a pair of contacts 188 which are carried by a suitable insulating block 189 fast to the fixed arm 183. During the normal operation of the machine arms 183 and 184 are in parallelism and abutment 186 keeps contacts 188 open as shown in Fig. 11. In the event of-a jam of the pusher mechanism these parts 188 are permitted to close in the manner shown in Fig. 12 to thus stop the operation of the machine in a manner to be hereinafter described.

Stacker construction Referring now to Figs. 3 and 4, a stacker which receives the completed punched cards delivered by feed rolls 122 comprises a bottom plate 123 which is fixed to a bracket 134'. This bracketis slotted as shown at 135 and substantially one-half of it is provided with threads 136 which normally enga the threaded vertical shaft 137. The brac at 134 is also provided with an u(pper extending portion 138 which is unthrea ed and ada ted to slidably bear against the threaded aft 137. It will be understood that the overhanging weight of the stacker plate 123 and the cards thereon will keep threads 136 engaged with the shaft 137. By lifting upward upon the stacker plate 123 the threads may be disengaged and the entire stacker elevated or lowered to any desired position.

As the cards are fed into the stacker provisionis made for automatically lowering the stacker cards and the stacker plate 123. This operation is effected by periodically-rotating threaded shaft 137 by means of a ratchet 139. To actuate this ratchet a' sliding pawl 140 is provided (Fig. 3), which pawl at its end remote from the ratchet is connected to an upwardly extending link 141 pivoted at its upper end to the frame part of the machine. The pawl 140 is retracted to the left by means of a spring 142 and is periodically Gownting and stopptng mechanism As previously explained provision is madefor setting the machine to puch a predetermined number of cards and then stop. Detailed operation of this .counting and stopping mechanism will now be given referring particularly to Figs. 1, 6, 7 and 8.

It will be assumed for explanation that it is desired to punch two cards and then stop the machine. The operator grabs unit setposition is shown in Fig. 6.

ting knob 75 and shifts the knob counterclockwise until the second graduation on the ratcheted dial is in alignment with index 71. It may be explained that unit setting knob is fixed to the ratcheted dial 70. The operator now starts the machine in the usual way by depressing start key 79. The machine then operates. At each complete rotation of the main operating shaft 92 acam 144 fixed to shaft 92 rocks a spring restored bell crank assembly 145 in a clockwise direction. Pivotally and spring connected to the bell'crank 145 is a drag'pawl link 146 carrying a pawl 147 (Figs. 6 and 7), which pawl cooperates with the ratchet teeth 148 on ratchet disk 7 0. Thus at each operation of the machine ratchet disk 70 is advanced one step in a clockwise direction. Units ratchet wheel 70 in addition to being provided with the units ratchet teeth 148 is provided at one point on its periphery with a deep ratchet notch 149. As shown in Fig. 6, this notch is disposed two steps away from the notch engaged by pawl 147. Upon the machine making two complete operations pawl 147 will drop into the deep notch 149 and thereupon engage one of the ratchet teeth 150, which teeth are disposed upon a sector ratchet disk 151 which has the hundreds setting handle '72 connected to it. Sector 151 is loosely pivoted upon a supporting stud 152 and is frictionally held in position by means of'suitable friction washers 153 disposed in cooperation with plate 70.and the hundreds graduating dial 74. Sector 151 carries a block 154 which is adapted to engage a flexible contact 155. Cooperating with this contact is a fixed contact 156 suitably fixed and insulated from the frame of the machine. The normal position of these contacts. is o n for the machine to continue to o erate. his en the pawl 147 engages the deep notch 149 it also en-- gages the ratchet teeth 150 on sector plate I 151 rockingsaid sector plate one step in a clockwise direction. and thus closing the contacts as indicated in Fig. 7. The closure bottom of the card magazine.

tion to adjusting the units ratchet plate by setting knob 75, the operator also adjusts the hundreds sector plate 151. This is done by grasping the handle 72 and swinging the plate counterclockwise until the desired number of hundreds on index plate 74 ali with index 73. The stopping operation Wlll then be the same as before except that the unit's ratchet disk 70 will make several complete revolutions before the stopping segment is finally brought up intocontact with the flexible contact 155.

Referring now to the circuit diagram of the machine (Fig. 21), contact 155 is connected to a line 157 which extends to and connects with the upper of a pair of contacts 158. These contacts 158 are closed simultaneously with the closure of start contacts 80 by the depression of the start key 79.

In the construction of the machine as shown in Fig. 8, the start key is located directly over the two pairs of contacts 80 and 158 and, when depressed, closes both of them. Both of them are likewise held closed by the latch 83. In Fig. 21 for clearness in the diagrammatic showing these contacts are shown one below the other. The contact 156 is connected to a line 159 which extends to one side of source 81. The other contact of contact pair 158 is connected to a line 160 which extends to a magnet 161 in which a return line 162 including a resistance 163 extends back to the other side of the source. The energization of magnet 161 either by the closure of contacts 155,156, or by the closure of other contacts as will be hereafter described, serves to attract an armature 164: and thereby release latch 83 permitting the contacts 80 to automatically open and thereby interrupt the circuit to the motor 82. Simultaneously the contacts 158 are opened so that the parts are set up for a subsequent operation. If it is desired to stop the machine operation at any time the operator can depress a stop key 165 thereby release latch 83 and stop the motor operation in a similar manner. In addition to stopping the operation of the machine after a predetermined number of cards have been punched provision is made for automatically stopping the operation of the machine should the cards become exhausted from the supply magazine or in 'case the pusher fails to operateproperly or in case the picker fails to o erate pro erly. These stopping devices wil now be escribed.

Referring to Figs. 15 and 20, pivoted to a fixed frame part of the machine are a air of arms 166. These arms have pivoted to them at 167 sup lementary arms 168 having upwardly exten 'ng ear portions 169 adapte to project through openin s 170 in the e arms 168 are normally ur ed forward relative to arms 166 by means 0 blade springs 171 and are limited in their relative upward movement by means of shoulders 172 which extend under the arms 166. The weight of the partsof the arms 166 and the arms 168 pivotally connected thereto is such that the assembly normall tends to rock anticlockwise. This anticloc wise rocking movement is normally prevented by means of a card in the card magazine engaging ears 169 in the manner shown in Fig. 15. After the last card has passed from the card magazine the rocking movement of the parts is no longer prevented and they; rock to theposition shown in Fig. 20, in w ich position notches 173 in the arms 166, engage a cross bar 174 carried by the picker arms 99. After such engagement has taken place the forward rocking. of the picker arms is prevented.

Referring now to Fig. 16, the arm 95 which, as previously explained, carries the V-shape jaw 97 and is connected to the pitman 94, carries on a bracket 175 a pair of contacts 17 6. So long as the cross shaft 96 is engaged within the V notch 97 thesecontacts will be held open by the cross shaft 98 engaging one of them in the manner shown in Fig. 15. In the event that the picker arm 99 is restrained against forward movement the contacts 176 under their spring action will move to closed position as shown in Fig. 20 inasmuch as t ey are no longer maintained open by engagement with shaft 98.

Referring now to the circuit diagram of the machine, the contacts 176 are disposed intermediate line 157 and line 159. The closure of these contacts will operate in a similar manner to interrupt the operation of the machine as the closure of the contacts 155 and 156 previously referred to.

The reason for providing the pivoted and spring connection intermediate the arms 168 and 166 is to prevent the picker arms from being suddenly released in the event that the supply of cards is replenished in the supply magazine 77. Should the cards be replenished the arms 168 will be pressed downwardly yieldingly relative to their supporting arms 166 and arms'166 will not disengage from bar 174 until the pitm'an has again returned to home position. Under these conditions the V notch will push the arms 79 slightly anticlockwise allowing the arms 166 to spring up to unlatcbing position.

Provision is made for stopping the following movement of the picker arms relative to itman 94 in the event that a card becomes 1ammed afterit has been artially removed from the card magazine 7. Referring to Figs. 3 and- 16, the arm 95 carries a pin 177, which in in case of'the normal engagement of sha 98 with the V jaw 97 is adapted to press rearwardly upon a wire 178, which wire extends to and connects with a awl 179 pivotally mounted on shaft 98. gVith normal engagement pawl 179 will be maintained eleward swinging movement after the mutilated card has been removed.

Provision is also made for interrupting the machine operation in case the card pusher structure fails to function properly and advance sufliciently to eject. a card from the die assembly. This means comprises contacts 188 which are arranged to be normally opened when the pusher structure functions properly and which clos'e upon the failure of the pusher devices to advance. Contacts 188 are likewise disposed between lines 157 and 159 and the closure of these contacts at any time in the machine operation will open the moto'r circuit and stop the operation of the machine in the manner previously described.

As previously mentioned there are certain instances when it is desired to punch dual holes in a given column in the card. These holes are ordinarily located in particular columns on the card and in such columnsI contemplate the providing of special interposer barsil" of the type shown in Figs. 17 and 18. These interposer bars are provided with the usual abutment-43 and shoulder42 and, in addition, the rear end of the interposeris slotted at 190 to receive'a supplementary bar 191. In practice a number of these bars 191 will be made up (proviged that, ers 4 are-at su plementary abutment shoul di erent positions relatively to the end 192 thereof. The selected supplemental interposer bar 191 will be placed in position in the slotted oove190and the supplemental abut 43 Wlll then cooperate to depress an extra unch in that column. To properly align t e supplemental interposer'bar and to prevent its dropping through'the slot 190 the ar 191 is provided with an eliminating pin 193 and the main interposer bar-'41 is provided with an abutment or a; cross-pin 194.

The interposerbarfl-{ mayibe-made ofspring metal so "as to grip theji su p plemental bar 191.

It may beexplainedthatin the event that the machinegaccidentallyl stops due to, the

closing of the safetynecessarytorriachine back vtohoime ppsition before it'earibe restarted; This can conveniently'eifected'bymeans of the manual crank handle 85. I
