This invention relates to a machine for forming sheet material into smaller portions and has reference more particularly to a machine for forming blanks such as index cards or other objects from sheet material such as cardboard or the like.

In the manufacture of index cards, the practice in the past has been to feed the sheet material to the punch press by hand. The result has been that a large amount of labor was necessary and the cost of manufacture, islorgling, stacking, etc., was unnecessarily in object of the invention is to provide a. machine which will receive strips of cardboard, form index cards of said strips and stack said cards, the entire operation being automatic.

Another object of the invention is to provide a machine. which will prepare index cards of the articulated type, or those which nest together, to expose a series of overlapping edges for the reception of indicia.

Another object of the invention is to provide a machine of the class described which will receive strips of material bearing a plurality of designating characters and form said strip into stacks of cards sorted in accordance with said characters.

A further object of the invention is to provide a machine which will punch index cards bearing attaching tongues and automatically count and stack the finished cards.

A still further object of the invention is to provide a machine having a drive shaft and feeding, punching and stacking mechanism all driven from said shaft; also to improve machines of the class described in other respects hereinafter specified and claimed.

Referring to the drawings by numerals, indicates a strip of cardboard or other sheet material which is of a suitable length and which supplies the stock. from which blanks such as index cards 36 may be made by means of my improved machine. In Figures 1-12 inclusive the position of the strip and cards in plan and elevation at various stages in their manufacture is shown. In Figure 1 the strip is shown ready to be advanced into the punch of the machine where attaching tongues 37 and attaching slots 38 are formed in the end of the strip as shown in Figure 2, where the end of thestrip lies in line with the shear or cut-off line 39 of the punch. Figure 3 shows one card 36 out from the strip and the tongues 37 and slots 38 formed on the end of the remaining strip while Figure 4 shows two finished cards and one partly finished card. Figure 5 shows all three cards 36 in finished form ready to be lifted into the card hop er in the form of stacks 40 as shown in ig ures 6 and 12. Figures 712in-' elusive are side elevations of the card during the different stages of manufacture as shown in Figures 1-6 respectively. When the stacks of cards 40 are complete with the required number of cards, such as 500 cards to the stack, the stacks are moved into a receiver by a suitable elevating mechanism into the position shown by the dot and dash lines of Figure 12, after which the operator can remove the stacks of cards from said receiver and wrap same for shipment.

It should be understood that my machine is suitable for making or punching out a large variety of cards and is manifestly not limited in use to the type of cards shown in outline in Figure 6. One of the other numerous types of index cards which may be formed on my machine is shown in Figure 15 where a pair of inwardly extending attaching tongues 41 are formed on said card 42, these tongues being adapted to engage a suitable slide to maintain said cards in nested position as shown in the patent to Hayes, 1,223,168. However, with the type of card shown in Figure 6, the cards are connected, chained or articulated together to form a series of cards as shown in Figures 13 and 14, by inserting the tongues 37 of one card into slots 38 of the adjacent card so that the free edges 43 of the cards in series are in visible, overlapping relation one to the other.

The machine for making the index cards comprises preferably, a pair of vertical standards or frame members 45 which may be in the form of castings having guideways 46 formed on their upper ends. These guideways are adapted to slidably receive the ends of a punch, actuating beam 47 which extends horizontally between the frames 45 (Figs. 16 and 17) and is adapted to simultaneously actuate a plurality of punches 48 cooperating with dies-49, the latter being rigidly secured to the frame members 45 by a suitable horizontal frame member 50. In order to reciprocate the punch beam 47 vertically, a transversely extending drive shaft 51 is rotatably mounted in suitable bearings 52 formed in the frames 45. This drive shaft 51 48 and dies 49 can be accurately adjusted.

It is customary to supply sheet material such as cardboard to the machine in a suitable form such asstrips 35 from which the cards 36 are punched and sheared. In order to advance the strips by a step by.v step intermittent movement under the punch 48, the end of the strip 35 is removably received in a carriage 59 which is provided with a clamping jaw 60 pivotally mounted on a pin 61 secured on said carriage 59 (Fig. 20). The clamping jaw 60 is in the form of a lever, the opposite arm 62 being engaged by a wedge member 63 secured on the end of a pin 64 so that the clamping jaw 60 is pressed against the strip 35 under the action of a spring 65 operating between the wedge 63 and a shoulder 66 on the carriage 59. The carriage 59 is slidably mounted for reciprocation on a dove tail track 68 (Fig. 22) formed in a track bracket 69 secured to the cross frame 90 50. The carniage 59 is normally urged to its rearmost position by a flexible strap 70, one end of said strap being securedto a spring pulley 71 urged to move in a clockwise direction as seen in Figure 18 by a coil spring 72 bet-ween a portion of the hub 73 and the shaft 74 on which the pulley 71 is rotatably mounted. At the rear of the track frame 69, a pulley bracket 76 is secured and an idler pulley 77 is rotatably mounted on a spindle 78 secured to said bracket 76. One end of the strap passes around the pulley 77 and extends horizontally to the carriage 59 where it is secured thereto in any suitable way such as by screws 79.-

\ In order to advance the carriage 59 toward the punch 48 with a. step by step, intermittent movement, a rack 81 is slidably mounted in the track frame 69 for reciprocating movement. The lower edge of rack bar 81 is provided with a dove tail groove 82 which receivcs a dove tail tongue 83formed on the upper'end of a coupling member 84 secured to a slide rod 85. The rod 85 is slidably mounted for reciprocating movement in suitable bearings 87 formed on the bracket 69 and the coupling member 84 has a downwardly extending flange 88 adj ustably secured to a slide bar 89 by means of a bolt 90 and slot- 91 connection. The slide bar 89 is suitably connected to the drive shaft 51 by a mechanism to be hereinafter described, so that said bar 89 and rack'bar 81 continuously reciprocate in a horizontal plane while the machine is in operation.

1,845,203 a l 3 s In a suitable groove 93 in the slide frame 69, a fixed rack bar 94 is detachably supported with its inner face in contact with the rack bar 81. Suitably spaced rack teeth,

95 are formed in the upper edge of the movable rack bar 81 and similarly spaced rack teeth 96 are formed in the upper edge of the fixed rack bar 94. The rack teeth 95 and 96 are in the form of abrupt shoulders facing forwardly of the machine, said shoulders being adapted to receive the lower ends 98 of a pair of pawls 99 pivotally mounted on ,a pin 100, the latter being secured to suitable flanges on the carriage 59. The awls 99 are urged to move in a counter-cloc wise direc- I? the lower end 98 of a pawl to carry said pawls will ' the strip is advanced towar and carriage 59 ahead again to a new, ad-

' vanced tooth 96 on the fixed rack 94. Thus by means of the racks 81 and 94 cooperating with the pawls 99, the carriage 59 carrying with an intermittent, step by step movement.

When the carriage 59 is in its foremost position closest to the punch 48 as seen in Figure 20, an arm 102 on a lever 103 lies in a position abutting a flange 104, the latter being secured to a slide bracket 105 which is mounted for limited reciprocating movement in a groove 106 formed in the slidebracket 69. The lever 103 is pivotally mounted on the pin 100 and the upper end of said lever has an arm 107 through which passes an adjustable, actuating bolt 108, the inner end of said bolt being adapted to bear against an arm 109 on a lever 110 pivoted on pin 111, which is secured to suitable flanges 112 on the carriage- 59. On the rear end of pin 64, is threaded a nut 114. on the forward end of which are a pair of shoulders 115 diametrically opposite one another and engaging a bifurcated arm 116 formed on the lower end of lever 109,

said shoulders 115 being adapted to prevent the accidental rotation of said nut 114 due to vibration- A laterally extending shoulder 117 is formed on the lever 103, said shoulder being adapted to engage the forward end 118 on pawl lever 99. At the proper moment when the carriage 59 has reached its position nearest the punch 48, the flange 104 is given a rearward movement by a mechanism to be hereinafter described, sothat the lever 103 is moved in a clockwise direction as seen in Figure 20, thus causing the bolt 108 toact on lever arm 109 so that pin 64 and wedge 63 are moved to the left and the clamping lever 62 the punch 48 moves in a counterclockwise direction about I pin 61 under the action of a spring 119 which extends between said lever 61 and a fixed in 120 onthe carriage 59,so that the clamping aw is released from the strip 35 which now has been reduced to one piece because of the. fact that other cards have been sheared from sald strip. It is now necessary to move thls last piece of strip 35 out of the punch 48 after the clamping jaw 60 has been released and for this purpose a pair of fingers 121 are pivotally mounted at their rearmost ends on a pm 123 secured to the upper end of a lever 124, the latter being pivotally mounted on a shaft 125 which is rotatably mountedin suitable bearings in the framework of the machine. The pair of fingers 121 are arranged one on each side of the carriage 59, and the foremost end of each finger is provided with a V-shaped clip 126 which is adapted to slide up an inclined cam surface 127 and engage the rearward edge of the strip 35 and push the last piece of said strip forwardly out of the punch 48.

When the carriage 59 has reached its positlon nearest the punch and the lever 103 has been acted upon by the flange 104 to release the clamping jaw 60 as above described, the clockwise movement of the lever 103 also acts on the forward end 118 of the pawl levers 99 and lifts the lower ends 98 of said levers free of the foremost tooth 95 of rack bar 81. The

carriage 59 then moves rearwardly under the,

action of strap and spring 72 until the carrlage is Stopped in its rearmostposition with its rear edge abutting against stop flange 128 on bracket 76. When the lever 103 has been moved in a clockwisedirection by flange 104, a shoulder 129 on the forward arm of a lever 130, engages the shoulder 117 on lever 103 so as to lock the wedge 63 in its real-most position against the action of spring 65, thus causing the locking jaw 60 to be held open ready for the reception of a new strip of cardboard. The lever 130 is pivotally mounted on a pin 131 secured in suitable bearings V on the carriage 59, and the rearward arm 132 of said lever 130 is provided with a'h'andle 133 which is adapted for manual actuation. When the carriage 59 has been moved to its rearmost position "by the action of strap 70 and spring 72, the locking jaw 60 now being open, the operator of the machine inserts a new strip of cardboard 35 into the locking jaw 60 and then presses downwardly on the handle 133 which causes the wedge 63 to be moved to the right under the action of spring 67 so that clamping jaw 60 now securely engages the rearward end of the strip 35. The manual actuation of the handle 133 also causes the shoulder 117 on lever 103 to be released from lever arm 118 so that the pawl end forwardly and causes the strip 35 to be advanced into the punch 48 wlnch forms the first card. 1

T he slide bracket 105 is maintained in its forward. position by a locking catch 135 which has a tooth adapted, under the action of a spring 136, to engage behind a shoulder 137 formed in the slide bracket 105. The can-11.135 is secured to a shaft 138 which is rotatably mounted in asuitable bearing 139 formed on the slide frame 69. To the end of the shaft 138 opposite the catch 135, is secured a lever 140, which, under certain conditions, lies in the path of travel of the lower end of a lever 141 which is pivoted by pin 142 tothe beam 47 which supports the punch 48. The lever 141 is thus given a vertlcal reciprocating movement by punch beam 47 and said lever is normally urged to move in acounterclockwise direction by a spring 144 extending between said lever and the punch beam 47. The counterclockwise movement of the lever 141 is limited by the arm 145 of a lever 146 which is rotatably mounted on astud 147 secured to the bearing 139. The lever 146 is thus urged to move in a clockwise direction as seen in Figure 19, under the action of spring 144 and lever 141 and this movement of lever- 146 is limited by a stop pin 148 secured to the bearing 139.

A second arm 150 of lever 146 lies in the path of travel of a flange 151 secured to the carriage 59 so that when said carriage advances to its foremost position, the flange 151 moves the lever 146 in a counterclockwise direction which in turn moves thelever 141, so that the lower end hereof contacts with the lever 140 and rocks the shaft 138 so that catch 135 is disconnected from the shoulder 137 on slide bracket 105. The slide bracket 105 is now free to move rearwardly under the action of a spring 153 which is connected between abell crank lever 154 anda fixed pin 155. The upper end of bell crank'lever 154 has a ball 156 which is mounted in a suitable socket 157 formed in slide bracket 105 so that said ball is permitted to move vertically slightly during the arcuate travel thereof on the end of lever 154. The lever 154 is secured to a rock shaft 158 which is rotatably mounted in suitable bearings in the slide frame 69. The end of shaft 158 opposite the lever 154 is provided with aclutch lever 160 secured thereto at one end. Thus when slide bracket 105 moves rearwardly until the shoulder 161 abuts against a shoulder 161' formed on the slide frame 69, the clutch lever 160 is moved vertically so that the end thereof disconnects from a notch 161 formed in a clutch pin 162. The clutch pin 162 is mounted for lateral sliding movement in the hub 163 of a pinion 164 which is rotatably mounted on urged to move to the left under the action of a spring 166 so that when the clutch lever 160 is withdrawn from said pin 162, the latter moves to the left so that the end 167 of said clutch pin will project into a recess 168 formed in the face of a collar 169, the latter being secured by a pin 170 to the shaft 51 adjacent the pinion 164. When the clutch pin 162 thus-engages the collar 169, the latter, shaft 51 and pinion 164 move in unison. The lower edge of lever 160 is bevelled away on one side so that downward m'ovement of said lever willenga e the recess 168 and move the pin 162 to t e right, out of engagement with the collar 169.

The pinion 164 meshes with a gear 171 which in turn is secured to a cam shaft 172, the latter bein rotatably mounted in suitable bearings 173 formed on the slide frame 69. The rotation of gear 171 and shaft 172 by pinion 164 causes the rotation of a cam 17 5 which is also secured to shaft 172. When the catch 135 is disconnected from shoulder 137 so that slide bracket 105 moves rearwardly and lever 154 moves in a counter-clockwise irection as seen in Fig. 18, a roller 176 rotatably mounted on an arm 177 of the lever 154, contacts with the outer periphery of the cam 175. After the carriage 59 has moved rearwardly to its rearmost position, the cam 175 acts on roller 176 to move the lever 154 in a clockwise direction sothat slide bracket 105 is moved forwardly until catch 135 again snaps into place behind shoulder 137 so that sai slide bracket 105 is then ready for a new cycle of operations. The cam 175 has a high point 179 which moves the slide bracket 105 to its foremost position where the catch 136 engages the shoulder 137. A further movement of the cam 17 5 then causes the cam surface to disengage from the roller 17 6 due to the shape of the cam 175, until the catch 136 is again released from shoulder 137.

Also secured to the shaft 172 is a cam 180 which hasan outer periphery adapted to be in rolling contact with a roller 181 rotatably mounted on the end of a lever 182, the latter being secured to the rock shaft 125. A high point 183 on cam 180 causes the roller 181 to rock the shaft 125 in a clockwise direction as seen in Figure 18, so that fingers 121 advance toward the punch 48 pushing the last end of the strip 35 out of the punch and .into the receiving mechanism. When the roller leaves the high point 183, a spring 184 secured between a lever arm 185 anda fixed pin 186, causes the fingers 121 to return rearwardly to their normal position.

The machine is designed so that it may be latter being formed on an elongate member 189 which has a pair of outstanding ears 190. Arms 191 extend outwardl from the slide frame 69 and a pair of para lel links 192 connect the outer ends of arms 191 with their respective ears 190. A pivot pin 193 rotatably connects the end of each link 192 with the ear 190 and a locking bolt 194 connects the opposite end of links 192 with the ends of the respective arms 191. Thus by loosening the bolts 194, the age 188 may be moved inwardly or outwardly with the parallel move ment provided by the links 192 so as to be adjusted to any width of strip it is desired to use. After the adjustment is made, bolts 194 are again tightened and the gage 188 is then held ri idly in place. A guide roller 195 is rotata ly mounted on a link 196, the

latter being pivotally attached by a bolt 197.

to the end of an arm 198 formed on the slide frame 69 opposite the arms 191. The purpose of the roller 195 is to engage the edge of the strip opposite the gage 188 so that thestrip is accurately positioned under the clamping aw 60 by the operator. In order to make cards of different widths, the rack bars 81 and 94 may be changed for other rack bars having teeth 95 and 96 of a different pitch.

In changing these bars, the bar 94 is first moved upwardly out of the groove 93 and the bar 81 is then moved laterally until the dove-tailed tongues 83ers disconnected from their respective dove-tailed grooves, after whlch the rack bar 81 may be moved vertically'away from the machine and new ones substituted.

The punch 48 is composed of detachable punch members 200 and 201 which operate in similarly shaped openings the die 49 so as to punch out the openings 38 and 202 respectively in the strip 35 thus formlng the slots 38 and the attaching ears 37 The punch 48 also includes a shearing knife 203 which is in the form of a knife edge operated against a shoulder 204 formed on the die 49, this shear being adapted to cut off the cards at the same time that the punches 200 and 201 operate on the following strip.

When the finished cards 36 are cut off by the shearing knife 203, they fall onto a par of movable bars 205 which have upstanding projections 206 formed along the upper edges thereof spaced apart substantially the width of the cards which are formed. With the spacing of the projections 206 shown in Figure 23, only three cards are designed to be formed from each strip and for narrower cards, additional projections 206 would be added to the upper edges of the bars 205. The projections 206 are formed on the upper edges of strips of metal 207 (Fig. 30) which are secured to the inner face of each bar 205 as by screws, not shown.

Especially for cards which are narrow in width, it is necessary for the end of the bar 205 to be closely abutting the shoulder 204 ed on the end thereof, said roller being on die49 so that the card will be deposited and properly positioned ahead of the rearmost projection 206 on the bars 205. The bars 205 are caused to move upwardl by a mechanism to be hereinafter describe so as to deposit the finished cards in a receiver 208 arranged above the bars 205. It is necessary for the bars 205 to move outwardly away from the knife 203 as well as upwardly so that a combined movement approximately along a 45 degree angle is obtained for the bars 205.

The u ward movement of the bars 205-is obtaine by means of a sleeve 210 which is upstanding arms 220 is adjustably secured to each of the saddles 217 and 218, said arms being secured to the bars 205 by means of long screws 221 extending downwardly through bars 205, arms 220 and being threaded into clamping strips 222 adjacent the lower ends ofthe arms 220, said clamping strip 222 being adapted to engage a tongue 223 formed on each saddle 217 and 218. By loosening the screws 221, the lateral distance between the arms 220 and bars 205 can be adjusted to suit any width of strip.

frame 213 A rack bar 225 is securedto the rear of m sleeve 210 extending outwardly through a 7 suitable opening in the bearing frame 226'.

Lever 227 has an arcuate gear 228 formed on its end which meshes with the rack 225.. The lever 227 is pivotally mounted on a stud 229 which is secured to the frame member 213. A second arm 230 of lever 227 extends rearwardly and has a roller 231 rotatably mountadapted to engage the outer periphery o a cam 232 which is secured to the shaft 172. The cam 232 has a high point 234 which is adapted to move the lever 227 in a counterclockwise direction as seen in Figure 23 so that gear 228 acts on rack 225 to lift the sleeve 210 and bars 205 vertically. The card receiver 208 is preferably in the forin of a pair of spaced metal walls 236 along the lower edge of which is formed an inwardly turned narrow flan e 237. When the cards 36 are lifted upward y by the bars 205, the outer ends of the card engage the flanges 237 so that continued upward movement ofthe bars 205 causes the card to bow upwardly in the center until the ends of the card snap past the flanges 237, after which the lowering of the bars 205 causes the card to rest on the up er face of the flanges 237. Continued a ditions of cards 36 from below causes the formation of a stack of cards 238 in the card receiver 208. In order to cause the forward movement of the bars 205 as said bars are moved upwardly, so that the rearward end of said bars do not interfere with the knife 203, a roller 239 is rotatably mounted on the saddle 218, said roller being mounted for sliding movement in a fixed cam groove 240 formed in the frame member 213, said-cam groove being adapted to move said roller forwardly as it raises, thus causing the bars 205 to move forwardly by rods 216 sliding in bearings 215.

\ As the cards are cut off by'the knife 203, it is desirable to deposit or arrange said cards along the bars 205 in the same succession or order in which they occurred in the strip 35. Thus the finished stacks of cards shown in Fig. 6 will have the designating numerals A, B and C in the same relative position in which they existed in the strip 35 shown in Figure 1. For this purpose bars 242 are provided, preferably two in number and positioned just outside of the bars 205. These bars 242 are given a motion by a mechanism to be hereinafter described, such that any iven point on said bars moves along the outine of a rectangle, the bars moving downwardly at the foremost end of their movement until their upper surface is below the upper surface of bars 205, the bars then moving rearwardly and at the rearmost position of their movement they raise vertically and lift the newly cut card from the bars 205. The next movement of the bars 242 is forwardly of the machine, which carries the newly cut card beyond the second projection 206 on the bars 205, after which the bars 242 lower and again deposit the card on the bars 205 in the second position. This cycle of movement of bars 242 is repeated twice, and when the third newly cut card is deposited in the first position-in the bars 205, the

latter lifts the three cards into the card reent spacing of the projectlons 244 for different widths of cards.

Each of the bars 242has a pair of laterally extendingspindles 246 secured thereto, said spindles being received in supporting bearing brackets 247 and being rigidly but adjustably secured therein by set bolts 248.

' Each of the bearing brackets 247 has a downwardly extending spindle 249 which is securely and adjustably received in bracket 250, being secured thereto by a set bolt 251, so that said spindles may be adjusted verti- 7 cally. A pair of parallel rods 253 is rigidly but detachably received in the brackets 250 being secured thereto by set bolts 254. A spider bracket 255 is provided with a bearmg 256 which is mounted for sliding movement on the outside of sleeve 210 and said bracket 255 has a pair of long bearings 257 which are adapted to slidably receive the rods 253. The rods 253 and bars 242 are given their vertical movement by means of a lever 258 which'is secured at one end to a rock shaft 259, the latter being mounted in suitable bearings in the frame member 213. The free end of lever 258 is provided with a laterally extending elongate opening 260 which engages a stud 261 secured in the bracket bearing 256. The shaft 259 is given a rocking movement by means of bifurcated lever. 262 secured thereto, the two arms 263 of sald lever being ofiset relative to each other and being provided with rollers 264 which engage the outer peripheries of a pair of con ugate cams 265 so that the rotation of shaft 51 and cams 265 causes the rocking of the shaft 259 with a positive movement in each direction.

The axial or longitudinal movement of the bars 242 is caused by the reciprocating slide bar 89 which extends forwardly from the rear of the machine. The forward end of the bar 89 is connected to the forward ends of rods 253 by means of a bracket 267 which has a pair of bearings 268 formed thereon adapted to receive the forward ends of said rods 253, the latter being secured thereto by set screw 269. The lower end of bracket 267 is provided with a slot 270 which slidably receives a pin 271 secured to the forward end of slide bar 89 so that vertical movement of the rods 253 relative to the bars 89 is possible. The bar 89 is given a reciprocating movement by means of a bell crank lever 273 which is rotatably mounted on a stud 274 secured to the frame member 213. The free end of lever 273 is provided with a roller 275 which is received between a pair of guide blocks 276, the latter being secured to the bar 89 by bolts 277 so as to permit the vertical movement of the roller 275 between said blocks when traveling in an arcuate path about the stud 274. A second arm 278 of the bell crank lever 273, extends rearwardly of the machine and is provided with a slot 279 at its outer end. A lever 280 is secured to a rock shaft 281 and the outer end of said lever 280 is provided with a slot 282 which is rotatably connected by a pivot bolt 283 to the slot 27 9. By adjustably securing the pivot bolt 283 along the slots 282 and 279, the throw of lever 273 relative to lever 280 can be adjusted through reasonable limits for accommodating strips 35 of different lengths. The shaft 281 is provided with a bifurcated lever 285, each arm 286 of which is provided with a rotatably mounted roller 287. The rollers 287 are adapted to engage diametrically opposite points on the peripheries a pair of cams 288 secured to the drive shaft 51 so that r the shaft 281 is rocked with a positive movement in each direction.

The walls 236 of card receiver 208 are positioned by and secured to standards 289,

' each of which has at its lower end a longitudinally extendin arm 290 adapted to be adjustably receive on outwardly extending studs 292 secured to the frame member 213.

Set bolts 293 in bearings 291 fix the card receiver walls 236 in proper position to accommodate cards of different lengths.

After the stacks 238 have built up so that there are, say, 500 cards in a stack, a counting mechanism is provided which will actuate an elevator 295 which lifts the stacks 238 upwardly into a stack receiver 296 which is located above the card receiver 208. The walls 297 of the stack receiver are preferably located directly above the card receiver walls 236 and arespaced apart therefrom to form' an opening 298. A narrow flange 299 is hingedly mounted on a hinge in 300 which is secured to the walls 236. prings '301 cause the flanges 299 to be urged to move inwardly so thatthe inner edge 302 thereof lies in thepath of travel of the'stack of cards 238 as it is moved upwardly. These cards press the flanges 299 outwardly and when the last card has been moved upwardly by said elevator 295, the flanges 299 snap inwardly into place and maintain the stack of-cards in its elevated position after the elevator 295 has again moved downwardly.

The elevator 295 is preferably in the form of an elongate plate which, in its lowermost position, extends between the bars 205. An elevator rod 304 is slidably received inside the sleeve 210 and terminates at its upper end in bracket 305 to which the elevator 295 is secured by any suitable means. At its lower end the rod 304 is slidably received in a bearing 306, and its upper end inside of sleeve 210. A bracket 308 is secured to the rod 304 between the bearing 306 and sleeve 210 and a roller lever 309 is pivotally mounted on each side of said bracket by means of a pin 310 to which the lovers are fixed. A roller 311 is rotatably mounted on the lower end of each of the levers 309 and said levers are adapted to rock in unison, their rocking movement being limited 1n each directlon by stop shoulders 312 formed on the bracket 308. A spring catch 313 secured to the bracket 308 is adapted to engage either of two catch grooves 314 formed in the upper end of lever 309 so as to secure the rollers 311 in the positions shown in full lines or in the positions shown in dot and dash lines of Figure 25.

The rollers 311 are moved'into the positions shown by dot and dash lines in Figure' 25, when, for example, 500 cards have been formed into each stack, 'by a mechanism to be hereinafter described. When the rollers 311 arein said dot and dash position, they lie in the sa th of travel of a pair of fingers 315 secure to a bar 315' which is carried on one extremity by a lever 315", (Fig. 16 and at its other extremity in the end of'a ell crank lever 316 which is mounted for rocking movement on a stud 317. The other arm 318 of the bell crank lever 316 is provided with a rotatably mounted roller 319 on the end thereof, which engages the outer periphery of a heart-sha ed cam 320, the latter being secured to a s aft 321. A pinion 322 is secured to the end of the drive shaft 51 and said pinion meshes with a gear 323 secured to the end of shaft 321, so that the latter is continuously rotated by the shaft 51, thus causing a continuous rocking movement of the finger 315 in an arcuate path adjacent to the shaft 304, as seen in Figure 25. When the roller 311 is moved from full position to dot and dash position, the fingers 315 engatge said rolls during the upward movement 0 the former and lifts the shaft 304 and elevator 295 upwardly to position the stack of cards in the stack receiver 296 (Fig. 30).

In order to move the rollers 311 into the dot and dash-position for engagement with the fingers 315 at a suitable instant, such as after the stacks consist of 500 cards each, a suitable counting mechanism 324 is provided which is of conventional design, and is mounted on a stud 325 which is secured to a portion of the frame member 69. This counter 324 is actuated by a lever 326 which is 1'0- tatably mounted onthe stud 325, saitl lever being provided with an arm 327 through the end of which passes an adjustable stop bolt 328 which is adapted to limit the counter clockwise rotation of said lever as seen in Figure 25. The other arm 329 of said lever is provided with a laterally extending pin 331 upon which is mounted a pawl 332 which actuates the counter wheels 333 in the usual manner. The counter 324 is provided with a sight opening 334 through which is exposed a portion of the counter wheels 333 so that the number of strips punched in units, tens and hundreds canbe seen at a glance. A spring 335 is secured on a pin 336 mounted on the end of lever arm 329, said spring being adapted to engage the pawl 332 and maintain said pawl in engagement with the teeth 337 of the ratchet wheel inside of the counter 324'.

The lever 326 is provided with a laterally extending pin 339 which lies in the oath of travel of' an arcuate series of pins 340 adjustably mounted near the periphery of gear wheel 171. ,The pins 340 are provided with handles 341 on the ends for manual actuation of said pins into and out of operative position in the path of pin 339. A pair of annular grooves 342 is provided in each pin 340 and a spring 343 is provided for each pair of pins 340, said spring 343 being adapted to snap into the desired grooves 342 and resiliently'maintain said pins 340 in operative or inoperative position. Several of the pins 340 counter 324 merely counts the movement of strips 35 which'are punched,which corresponds to the number of cards in each stack 238. Thus the counter 324 will insure the same number of cards in the stacks 238 reardless of the width of the cards punched. %)n the side of the counter 324 opposite the .lever 326, is rotatably mounted a cam 344 hav-.

ing a pair of diametrically opposite depressions 345. This cam 344 is so geared to the counter wheels 334, that it makes one complete revolution for each thousand strips punched, or in other Words, it is actuated through one tenth of a revolution at the end of the punching of each hundred strips.

A lever 347 is rotatably mounted on a stud I 348 secured to the frame member 69 and the outer end of said lever is provided with a rotatably mounted roller 349 which is adapted to engage the periphery of cam 344. A second arm 350 of lever 347 is pivotally connected by a connecting rod 351 to an arm 352 of a T-shaped lever 353 which is pivotally mounted on a stud 354 secured to the bearing bracket 306. The length of the connecting rod 351 may be adjusted by means of a nut 355 so that the desired throw of the lever 353 is secured. A pin 357 is secured on the end of lever 353' and a trigger lever 358 is mounted for rocking movement on said pin. A shoulder 359 is provided on the lever 358, said shoulder being adapted to engage a pin 360 secured to the lever 353 so as to limit the counter clockwise movement of lever 358 as seen in Figure 25 under the action of a spring 361, the latter being secured between the end .of said lever 358 and a pin 362 secured to the lever 353. A spring 363 conmeets the lever 353 with a pin 364 secured to the bearing bracket 306 so that the lever 353 is continuously urged to move in a clockwise direction as seen in Figure 25, about the pin 354, said movement being limited by the contact of the roller 349 on the outer periphery of cam 344. When the roller 349 drops into the cam recess 345 after 500 strips have been punched, the arcuate end 366 of lever 355 contacts with the roller 311 and moves the latter into the dot and dash position as shown in Figure 25, where it lies in the path of travel of the upwardly moving finger 315, thus causing shaft 304, elevator 295 and stack of cards 238 to be moved upwardly.

vSince the movement of finger 315 is not synchronized with the movement of lever 358, it might so happen that the finger 315 would be in the upper part of its stroke when the roller 311 is moved to dot and dash position by the lever 358. Accordingly a cam surface 367 is provided on the lower side of finger 315 which is adapted to move the roller 311 back out of the way of finger 315 during the downward movement of the latter. Howpver, the roller 311 under such conditions is again quickly moved into dot and dashposition by the lever 358 to be acted upon and raised by the finger 315. As the roller 311 moves upwardly under the action of finger 315, near the upper part of its stroke, it contacts with a cam surface 369 formed on the upper end of a lever 370, the latter being rotatably mounted at its lower end on the pin 354. This lever 370 is urged to move in a clockwise direction by a spring 371, said movement being limited by a stop pin 372 provided on the bearing bracket 306. The contact of roller 311 with the cam surface 369 moves the lever 370 in a counterclockwise direction, as seen in Figure 25, until said roller 311 lies above the lever 370, whereupon the lever 37 0 again snaps in a clockwise direction until limited by stop pin 372. The downward movement of finger-315 now drops the roller 311 onto a downwardly inclined cam surface 373 on lever 370 which moves the roller 311 and lever 309 in a clockwise direction to the full line position of Figure 25 in which position the roller 311 may move downwardly past a shoulder 374 formed on said cam 373. As the roller 311 continues downwardly, it strikes a substantially horizontal cam surface 375 formed on the lever 358, as shown in Figure 29, and depresses the latter against the action of spring 361. The lever 358 is moved to the left after the hundred strips have been punched thus disengaging from the roller 311 and permitting the lever 358 to rise upwardly under the action of spring 361 to its uppermost position, where it is ready for a new cycle of operations.

The operation of the machine is briefly as follows:

The punches 48 secured to punch beam 47, are reciprocated vertically by the rotation of drive shaft 51 acting through eccentric 54 and connecting rod 56. As said punches 48 are reciprocated vertically relatively to the dies 49, a strip of cardboard 35 is moved into each punch with intermittent motion so that finished cards 36 are successively punched out and sheared from the stock by a knife 203 on said punch 48. This intermittent feeding operation is accomplished by a carriage 59, the forward intermittent movement of which is started after the operator places the strip 35 in clamping jaw 60, by manual,

of the strip 35 between clamping jaw 60 and carriage 59.

The forward movement of carriage 59 is continued until flange 151 strikes lever arm 150 which causes lever arm 145 to move vertically reciprocating lever 141 into the path of lever 140 so that the latter is moved downwardly thus releasing catch lever 135 from slide bracket 105 and permitting the latter to move rearwardly under the action of lever ball 1.56 actuated by spring 153. The rearward movement of slide bracket 105 causes the flange 104 to actuate lever arm 102 and withdraw wedge 63 from the clamping lever 62, thus releasing the clamping jaw 60 from the last card of the strip. The movement of shaft 158 moves the clutch lever 160 upwardly so that clutch pin 161 moves into engagement with collar 169 and starts the rotation of gear wheel 171 which is mounted on shaft 17 2. A cam 180 on said shaft 172 now actuates a roller 181 and moves lever 124 in a clockwise direction which causes fingers 121 to move to the right as seen in Figure 18 and transfer the last piece of the strip 35 from the punch 48 to the stacking mechanism. The actuation of lever arm 102 by flange 104 not only withdraws the wedge 63 from clamping lever 62 but also raises the pawls 99 from the rack teeth 95 and 96 and the entire carriage 59 then moves rearwardly of the machine under the action of strap and spring 72.

As the finished cards drop from the knife 203 after being sheared from the strip, they drop onto the bars 205. Bars 242 then move downwardly from the position shown in Figure 23 and then rearwardly of the machine until the rear end of bars 242 extend under the card resting on bars 205. The bars 242 then move upwardly lifting the card from bar 205, and the bars 242 then move forwardly of the machine, carrying the finished card to a new, advanced position on the bars 205, this card being deposited on the bars 205 by downward movement of the bars 242. This cycle of movements of the bars is continued until the finished cards are deposited on the bars 205 in the order in which they appeared in the strip 35. The bars 205 then move upwardly along a 45 degree line and push the cards 36 upwardly beyond flanges 237 into the card receiver 208 where said cards gradually build up a stack of cards 238.

The vertical reciprocating movements of the bars 242 are obtained through lever 258 acting on spider bracket 255, the latter supporting horizontal slide rods 253. The lever 258 is rocked from drive shaft 51 by a bifurcated lever 262 having rollers 264 acting on cams 265. The horizontal reciprocating movement of bars 242 is obtained by lever 273 having roller 275 which moves slide b v 89 with a reciprocating movement, the bars 242 being connected through rods 253 and bracket 267 to the end of bar 89 by a slot 270 and pin 271, the latter permitting the vertilcal movement of bars 242. Lever 273 is actuated through lever 280 connected to shaft 281, the latter being rocked from drive shaft 51 by a bifurcated lever 285 having rollers 287 acting on cams 288.

The vertical movement of bars 205 is obtained by upward movement of a sleeve 210 which supports bracket 214 and slide bars 216, the latter having saddles 217 and 218 which support the bars 205 through arms 220.

' The sleeve 210 is reclprocated vertically by gear 228 engaging rack 225, said gear being formed on the end of lever 227 which is locked by roller 231 engaging the cam 232 on shaft 172. The horizontal reciprocation of the bars 205 is obtained by roller 239 engaging fixed guides 240 during the upward movement of bars 205.

When 500 strips have been punched, shaft 304 and elevator 295 move upwardly carrying with them the finished stacks of cards 238 into the stack'receiver 296, after which the elevator 295 moves downwardly leaving the card stacks resting on spring pressed flanges 299. The upward movement of shaft 304 is obtained after 500 strips have been punched, by the action of lever 316 having roller 319 engaging cam 320 on shaft 321. Shaft 321 is driven through a gear 323 meshing with the pinion 322 on shaft 51. v The lever 316 carries a air of fingers 315, into the path of travel of which a pair of rollers 311 on shaft 304 is moved at the proper time.

The movement of strips punched is recorded by counter 324 which is actuated by pins 340 acting on a pin 339 on counter lever 326, the pins 340 being or gear wheel 171. The counter 324 actuates a cam 344 so that a roller 349 engaging the periphery of said cam, drops into the recess 345 at the proper moment and actuates lever 347, rod 351, lever 353, the latter moving lever 358 so that arouate cam surface 366 moves the roller 311 into the path .of travel of the fingers 315 so as to elevate shaft 304 and elevator 295. The upward movement of rollers 311 causes one of said rollers to engage cam surface 369 on lever 370 and rocks said lever 370 about pin 354. Downward movement of the fingers 315 drops the rollers 311 one of which engages. cam surface 373 which throws the rollers 311 into full line position, as seen in Figure 25, and the said rollers move downwardly into the position shown in Figure 29. The movement of roller 349 out of cam recess 345 then moves the lever 358 out of contact with rollers 311 ready for a new cycle of operation.

As a modified form of operation, the knife 203 may be removed from the punch 48 in which case the cards are not severed one from the other but the strip remains intact after the tongues 37 or 41 are formed thereon. In use, therefore, the punched strips are typewritten and the typewritten cards are then severed one from the other by the user. The word blank in the following claims, therefore, signifies the cards or strips either in their severed or in their unsevered form.

I would state in conclusion that while the illustrated example constitutes a preferred embodiment of my invention, I do not limit myself precisely to the details herein described, since manifestly the same can be con- 'siderably varied without departing from the spirt of the invention as defined in the appended claims.
