  • ABSTRACT Devices for counting paper money, food stamps, and the like which include a cyclically operable counting head designed to displace seriatim succeeding items in a stack of items to be counted and a register which is advanced during each cycle of operation of the counting head to provide a count of the items in the stack.
  • ROBERT D YOUNG ATTORNEYS PATENTEDJAN 16 I973 3,711,015 SHEET 3 [1F 6 F T 28 a I I90 I52 W
  • This invention relates to counting devices and, more particularly, to devices for counting the number of items in a stack of paper money, food stamps, or similar items.
  • the item engaging components of the counter head contact only areas of the items which are relatively free from defects; i.e., which are not torn off, dog-cared, folded, etc. This further contributes to the accuracy of the counting operation.
  • Another novel feature of the present invention is a unique arrangement by which the operator can depress a single lever and simultaneously displace a holddown and the counter head to facilitate the removal of one stack of counted items and insertion of a new stack and, also, declutch the counter head and/or shut off the motor which drives it to prevent the counter head from cycling until insertion of the new stack of items is completed.
  • Yet another feature of the invention is a novel arrangement which automatically terminates the operation of the counter head when the last in a stack of items is counted.
  • Still another feature of the invention is an arrange- I ment for controlling the counting speed. This for example, permits the operator to adjust the counting speed so that the denomination of currency can be checked as it is counted.
  • Another advantage of the invention is ease of operation. Alignment of the stack of items relative to the counter head is not critical, and it is not necessary to remove the bands when banded items are being counted. Furthermore, due to the manner in which the ends of the items being counted are displaced, optical scanning devices can be readily employed to check denomination, etc., thereby relieving the operator of even this task.
  • a related and important object of the invention is the provision of novel, improved devices for counting paper money and the like which are more accurate than those heretofore proposed.
  • FIG. 1 is a pictorial view of counting apparatus in accord with the principles of the present invention
  • FIG. 2 is a plan view of the counting apparatus, the cover of the apparatus being broken away to show certain of its internal components;
  • FIG. 3 is a plan view of the apparatus with a cover and the counter head of the apparatus removed;
  • FIG. 4 is a bottom view of the counting apparatus
  • FIG. 5 is a bottom view of the counter head
  • FIG. 6 is a bottom view of the counter head with a holddown member removed
  • FIG. 7 is a fragmentary view of the apparatus which shows the details of a clutch incorporated therein.
  • FIGS. 8-10 are fragmentary sections through the counting apparatus, showing the counter head in different stages of its operating cycle.
  • FIGS. 1-4 depict a counting device or counter 18 constructed in accord with the principles of the present invention.
  • Counter 18 includes a base 20 for supporting a stack 22 of items 23 to be counted, a cyclically operable counter head 24 mounted on the base and drive-connected to a motor 26 by a drive train identified generally by reference character 28 (see FIG. 4), and a register 30 for showing the number of items counted by the counter head.
  • a removable cover 32 surrounds the majority of the components disposed above base 20.
  • counting device 18 Operation of counting device 18 is controlled by an on-off switch 34, a counting speed regulating control 36, and an arrangement including a microswitch 38 and an actuator 40 for automatically stopping the counting operation when the last item in a stack is counted.
  • Counting device 18 also includes a holddown 42 for the items being counted and a handle or actuator 44 which, when depressed, stops the counting operation and raises the holddown and counter head to facilitate removal of the stack of counted items.
  • the major components of counter head 24 are a support assembly 46, a pusher mechanism 48, and a pick-up mechanism 49, which includes a rotating pick-up member 50.
  • the pusher mechanism first displaces the ends of the bills or other items being counted to break any seal between the item being counted and the item thereadjacent. The pusher mechanism then deforms the end of the item being counted to form a loop therein.
  • Pick-up member 50 carries a pick-up member 52 and has a wedgelike portion 54 extending from the pick-up member. As member 50 rotates, pick-up member 52 slides into the loop formed by the pusher mechanism. wedgelike wall portion 54 follows the pick-up member into the loop and separates the end of the item 23 in which the loop is formed from the corresponding end of the item therebeneath.
  • support assembly 46 includes a vertically extending cylindrical member 56 to which a support member 58 having a flange 60 is attached.
  • a platelike holddown member 62 having an upturned edge portion 63 is fixed to the bottom of member 58 as by screws 64.
  • member 62 rests on the stack 22 of items being counted and holds the items 23 down to insure the proper operation of pusher mechanism 48.
  • a depending pin 66 is fixed to the flange 60 of support member 58 by a fastener 67 (see FIG. 8).
  • Pin 66 extends downwardly from flange 60 through holddown member 62, an aperture 68 in an item support member 70 fastened to the top of base 20, and an aligned aperture (not shown) in the base. This pin keeps support assembly 48 from rotating during operation of counter head 24.
  • the pusher mechanism includes a generally U-shaped bracket 72 pivotally fixed to support lugs 71 as by setscrews 73 which extend through the legs 74 of the bracket and engage lugs 71.
  • a second pusher member 76 is fixed to bracket 70 as by a pivot member 78. This pivot member extends through member 76 and a tongue 80 on bracket 72 which is fitted into a recess 82 at the rear end of pusher member 76.
  • Pusher member 76 which extends throughv a notch 83 in holddown member 62, carries an item engaging member 84.
  • This member is adjustably fixed to pusher member 76 as by a screw 86 which extends through a slot 88 in member 84.
  • the lower edge 90 of member 84 is sharpened so that member 84 will stay in engagement with the item 23 being counted as the-loop is formed in the latter (edge 90 may be continuous as illustrated in the drawing, or may be serrated, if desired).
  • the U-shaped bracket 72 of pusher mechanism 48 is biased in an upwardly or counterclockwise direction relative to support assembly 46 by a spring 94.
  • One endof this spring is hooked over a pin 96 fixed to pusher member 76 and the other over bracket 72.
  • a spring 98 journalled on pivot member 78 biases pusher member 76 downwardly relative to pusher mechanism bracket 72.
  • One end of this spring engages the top of pushermember 76 and the other the bottom side of U-shaped bracket 72.
  • the final component of the pusher mechanism is a cam follower 100.
  • the cam follower is rotatably mounted on a shaft or pin 102, which is fixed to or integral with and extends upwardly from U-shaped bracket 7 2.
  • the pick-up member 50 of this mechanism is a shell-like structure of circular cross-section having a lower edge 106 adapted to rest on the uppermost item 23 in the stack 22 of items being counted.
  • the inner surface 110 of the side wall 1 12 of the member acts as a stop against which the right-hand end portion 114 of the item being counted as shown in FIG. 8 may be positioned by pusher mechanism 48 to form a loop 116.
  • pick-up member 50 also carries a pick-up member 52. More specifically, as best shown in FIGS. 1 and 2, pick-up member 52 is fixed to the end of the portion 54 of the member, which has an up wardly inclined surface 120. This gives the wall portion 54 a wedgelike configuration. As counter head 24 rotates in a counterclockwise direction as shown in FIG. 1, pick-up member 52 enters the loop 1 16 formed in the bill or other item being counted. Member 52 is followed by the wedgelike portion 54 of member 50, which displaces the end 114 of the item upwardly until the free end 114 of the item being counted rides on the upper edge of member 50. This separates the end of the item from the like end of the item 23 therebeneath.
  • member 50 also includes an integral, depending, centrally located boss 122. Formed on the lower edge of boss 122 is a cam 124 which cooperates with cam follower 100. More specifically, as member 50 rotates from the position shown in FIG. 1 to that shown in FIG. 10, cam 124 acts upon cam follower 100 to operate pusher mechanism 48 first to the position shown in FIG. 8 and then to the position shown in FIG. 9 and finally allows it to return through the position shown in FIG. 10 to the FIG. 1 position under the influence of springs 94 and 98.
  • a bearing 126 extends upwardly through the cylindrical member 56 of support assembly 46.
  • Member 50 is fixed to bearing 126 by a threaded retainer 128 which engages a boss 130 at the top of the member.
  • Retainer 130 is then spot welded or otherwise fixed to boss 130 so that member 50, retainer 128, and bearing 126 rotate as a unit about the member 56 of support assembly 46.
  • bearing 126 terminates in a radial flange 132 at its lower end. This flange engages the lower edge of a recess 134 in support assembly member 58 and couples pick-up mechanism 49 to support assembly 46 while allowing relative rotation between the two.
  • counter head 24 is mounted for vertical sliding movement on a vertically extending shaft 136.
  • pin 66 keeps support assembly 46 from rotating in the manner described above.
  • Pickup mechanism 49 is fixed to shaft 136 for rotation therewith as by a key 138 fitted in cooperating recesses 140 in bearing 126 and 142 in shaft 136.
  • Shaft 136 extends through holddown member 62, item supporting member 70 and the upper wall 144 of counter device base 20 and is supported from the top wall of the counter base in an appropriate bearing (not shown).
  • This shaft is driven or rotated by motor 26 through the drive train 28 mentioned above. More specifically, motor 26 has an output shaft 148 which extends upwardly through the top wall 144 of base 20.
  • a pulley 150 which is the input member of drive train 28, is fastened to the upper end of shaft 148 for rotation therewith.
  • An endless belt 152 is trained around pulley 150 and around a pulley 154 joumalled on and rotatable about an intermediate shaft 156.
  • Shaft 156 is rotatably supported in any suitable manner from the upper wall 144 of counting device base 20.
  • clutch input member 158 is also journalled on and rotatable about shaft 156.
  • Clutch input member 158 is connected in any convenient fashion to pulley 154 for rotation therewith.
  • Clutch 160 also includes an output member 162 fixed to shaft 156 for rotation therewith and a lug 164 pivotally fixed to clutch member 158 and engagable in a recess 166 in clutch output member 162. With lug 164 engaged in recess 166, pulley 154 drives shaft 156 through clutch input member 158, lug 164, and clutch output member 162.
  • a sprocket 168 is fixed to the lower end of shaft 156.
  • a cooperating sprocket 170 is fixed to the lower end of counter head shaft 136 for rotation therewith, and a sprocket chain 172 is trained around cooperating sprockets 168 and 170. Accordingly, with motor 26 energized, shaft 136 is rotated through drive train 28 in a counterclockwise direction as indicated by arrows 173 in FIG. 1.
  • teeth 174 are formed on the upper end of clutch output shaft 156 to provide a gear 175.
  • the teeth of gear 175 mesh with the teeth 176 of a gear 178 fixed to or integral with the input shaft 180 of register 30.
  • This register may be of any desired type, but is preferably equipped with a reset 182 so that the count indicated by the register can be returned to zero after a stack of items or series of stacks has been counted.
  • shaft 156 drives or rotates register input shaft 180.
  • Counter head 24 separates the end 114 of an'item 23 from stack 22 once in each revolution, and the ratio between gears 175 and 178 is selected so that the count indicated by register 30 will be advanced by a predetermined increment during each revolution of counter head 24. Accordingly, the count indicated by the register will reflect the number of items which have been separated from stack 22 by the counter head.
  • the holddown 42 by which the items being counted are kept in position on base 20 while their ends 114 are being separated by counter head 24 is pivotally fixed to an elongated lever 184 by a pin 186 which extends through the forward end of the lever and a boss 188 on holddown 42. From holddown 42 lever 184 extends rearwardly through a slot 187 in cover 32.
  • Rod 190 extends through and is pivotally mounted in brackets 192 and 194 which are fixed in any conveniently fashion to the bottom side of the top wall 144 of base 20.
  • a lever 196 extends forwardly from the end of pivot member 190 adjacent bracket 194. Journalled between the forward end of lever 196 and the top wall 144 of base 20 as on a pin 198 is a compression spring 200. Spring 200 biases lever 196 away from the bottom side of the base upper wall. Accordingly, lever 184 and holddown 42 are biased downwardly toward the upper surface of the base top wall as shown in FIG. 2. Spring 200 thereby provides a biasing force to assist in keeping the stack 22 of items 23 properly positioned on supporting member during the counting operation.
  • Handle or actuator 44 is provided to lift or move holddown 42 away from the supporting surface of member 70 and thereby facilitate the insertion and removal of stacks 22 of items to be counted.
  • Handle 44 is formed integrally on or fixed to the forward end of a lever 202 which extends rearwardly through a slot 204 in the front wall 206 of base 20.
  • the rear end of lever 202 is fixed to or made integral with a transversely extending pivot member 208.
  • the pivot member is journalled in support bracket 192 and in a support bracket 210 fixed to the lower side of base top wall 144 in spaced relation to bracket 192.
  • a rearwardly extending member 212 to which a transversely extending shaft 214 is fixed.
  • Journalled on shaft 214 is a follower or roller 216. This follower engages the lever 184 to which holddown 42 is fixed and rotates it upwardly as shown in FIG. 2 when actuator 44 is depressed.
  • Actuator 44 is maintained in its normal, inoperative position by a spring 218 which surrounds transversely extending shaft 208.
  • spring 218 engages the top side of lever 212.
  • the other end extends through a slot 222 in base top wall 144 and engages the upper sur face of the top wall.
  • pivot member 224 Pivotally journalled in brackets 192 and 194 adjacent pivot member is a second pivot member 224. Fixed to pivot member 224 adjacent one end thereof and extending through a slot 226 in actuator 184 for engagement by roller 216 is a forwardly extending actuator member 228. A second, forwardly extending actuator member 230 is fixed to pivot member 224 at the end thereof adjacent bracket 194. An elongated actuating member or actuator 232 extends from member 230 upwardly through a slot 233 in base top wall 144 and terminates in a loop 234 (see FIG. 3) which abuts the holddown member 62 of counter head 24.
  • Roller 216 moves upwardly when actuator 44 is depressed as discussed above.
  • the roller engages the forward end of actuator member 228, moving it upwardly and, accordingly, moving member 230 and actuating member 232 in the same direction.
  • Actuator 232 consequently raises counter head 24 when handle 44 is depressed, facilitating the removal of the stack of items which has been counted and its replacement with a new stack.
  • spring 218 restores actuator 232 to its inoperative position. This allows the holddown member 62 of counter head 24 to engage the top of the new stack of items to be counted to retain the items in position.
  • an actuator 235 including a bushing portion 236 is rotably mounted on pivot member 208 adjacent actuator 212.
  • This actuator also includes a rearwardly extending lever 238 with a transversely extending lug 240 fixed to its free end. Lug 240 is biased against actuator 212 by a spring 242 journalled on pivot shaft 208 between actuators 238 and 212.
  • lever 238 When operator 44 is depressed to move actuator 212 upwardly, the rear end of lever 238 also moves upwardly. As this lever moves upwardly, it engages a clutch actuator 244 and pivots the actuator in a clockwise direction as shown in FIG. 3 against the bias of a spring 246. As the actuator pivots, a vertical flange 247 at its left-hand end moves upwardly, pivoting the drive lug 164 of clutch 160 upwardly out of recess 166. This disengages clutch members 158 and 162 and stops the operation of counter head 24 and register 30 although motor 26 continues to run.
  • Actuator 244 is pivotally supported from base top wall 144 by a pivot pin 248 which extends through brackets 250 mounted on the base and actuator ears 251.
  • Biasing spring 246 is disposed between an elongated actuator arm 252 and the top wall 144 of counter base and is retained in place as by a pin 253.
  • While the illustrated type of clutch is not essential, it is preferred. Irrespective of when handle 44 is depressed, the clutch input and output members are not disengaged until the input member 158 rotates to the position where actuator flange 247 engages and unlatches lug 164. Accordingly, it can be insured that the clutch always disengages at the end of the operating cycle, even if handle 44 is depressed at an intermediate point of the cycle.
  • clutch actuator 244 pivots further in a clockwise direction as shown in FIG. 3. This causes the contacts of microswitch 38, which is mounted on actuator arm 252, to open, interrupting the flow of current to motor 26 and stopping the motor.
  • counter head 24 and/or motor 26 can be terminated any time during the counting operation by depressing lever 44 in the manner just described.
  • the operation of counter head 24 is automatically terminated after the last item 23 in a stack 22 is counted by the actuator 40 referred to above.
  • actuator 40 is pivotally supported in a bracket 260 fixed to the lower surface of counting device base top wall 144.
  • a finger-like portion 262 of the actuator extends upwardly through a slot 264 in base top wall 144 into the path of rotation of counter head pick-up member 50.
  • Finger 262 is engagable by a loop member 266 which is fixed to the inner surface 110 of the side wall 112 of member 50 by bracket 268 and positioned by guides 270 and 272.
  • actuator 40 is covered and held down by the end portion 114 of at least one item 23. However, as the last item is counted, its end portion 114 is separated from support member 70, exposing actuator 40 for engagement by loop 266. As counter head 24 rotates, loop 166 engages and rocks actuator toward the front of the counting device as shown in FIG. 3.
  • a depending cam portion 274 is formed on actuator 40. As actuator finger 262 is rocked forwardly, cam portion 274 depresses lever 202; and clutch 160 is disengaged in the same fashion as when handle 44 is depressed to automatically stop the counting operation.
  • the first step in counting the number of items 23 in a stack 22 is to depress operator 44. This lifts counter head 24 and holddown 42 away from the item supporting surface of member 70, permitting a stack 22 of items to be slid onto this surface under the holddown and holddown member 62 of the counter head. Handle 44 is then released, lowering holddown 42 and holddown member 62 onto the top item 23 in the stack. The weight of the counter head and holddown together with he biasing force exerted by spring 218 keep the items properly positioned during the subsequent counting operation.
  • switch 34 With the stack 22 of items 23 positioned on member 70, switch 34 is moved to the on position to energize motor 26.
  • the motor accordingly rotates shaft 136 and counter head pickup assembly 50 in the counterclockwise direction shown in FIG. 1 through the drive train 28 discussed above (FIG. 1 shows counter head 24 in its rest or initial position).
  • cam 124 depresses cam follower 100. This operates bracket 72 of pusher mechanism 48 and pusher member 76 from their initial or rest positions shown in FIG. 1 first to the positions shown in FIG. 8 and then to those shown in FIG. 9.
  • the sharpened edge on member 84 engages the edge portion 114 of the top item 22 and then pushes this edge portion in the direction shown by arrow 276 toward the inner surface of pick-up member wall 112 to form the loop 116.
  • the movement of the two pusher mechanism members is such that the sharpened edge 90 is first engaged with the item 23 at a relatively steep angle to set the edge. Thereafter, little downward force is exerted on pusher member 84, the latter moving generally parallel to stack 22. The net result is a shoveling action of the pusher mechanism in forming the loops 116 in items 23.
  • a small pad 282 of a resilient material having a relatively high coefficient of friction is preferably mounted on support member 70 in the path of edge 90. This pad keeps edge 90 from damaging member 70 and vice versa. It also helps to keep the free ends 114 of the last few items in each stack in place as they are counted.
  • register input shaft 180 is driven through the arrangement described above, advancing the count shown by register 30 to reflect the number of items which have been counted.
  • a down counter may be substituted for register 30 and used to stop the operation of counter head and/or motor 26 when the desired number of items have been counted.
  • the counting operation can be stopped at any point without releasing the stack of items being counted. This is accomplished by depressing operator 44 only to the extent necessary to disengage clutch 160 without raising lever 184 or counter head 24.
  • speed control 36 As indicated above, the speed at which counter head 24 cycles can be controlled by speed control 36.
  • This control is typically a conventional variable resistance wired in series with motor 26. Since numerous satisfactory motor speed controls are commercially available, it is not believed necessary to describe this component of counting device l8'further herein.
