The invention provides a currency dispenser which may be selectively set to dispense one or more bills totalling the selected amount of from one dollar to hundreds of dollars. The dispenser may include two dispensing units quickly detachable from one another, the first having one tray of a stack of one dollar bills on edge and a second tray of a stach of tive doliar bills on edge and the second unit having one tray of a stack of ten dollar bills on edge and a second tray of a stack of twenty dollar bills on edge. Preferably there is a feed from each tray which moves the end bill to a pair of feed rollers with a double bill detecting feeler just beyond which reverses the drive of the feed rollers to regurgitate any plurality of bills being fed therethrough, and also a counting or sensing feeler beyond the detecting feeler actuated by each bill for actuating a selectively set control circuit. The bills fed from the two trays of the iirst unit are directed into a collecting guide with a separator guiding the bills edgewise into the guide, and the bills fed from the second unit are similarly collected in a stack on edge in a second collecting gruide extending in the same direction as the first guide. Then the bills are fed endwise from the guides and are deected into a receiving coliector from which they may be removed by the operator. Preferably the feed rollers have staggered annular grooves with raised annular contacting portions having sharp corners to insure feed of each bill travelling between the rollers.

Referring now in detail to the drawings, the currency dispenser shown therein includes a first dispensing unit 21 (FIG. 1), a second dispensing unit 22 and a control unit The units are quickly detachable from one another for substitution of other identical units for maintenance or the like, and the unit 2i includes a drive motor 24 (FlGS. 3, 7 and 8) which drives the unit 2l through a belt 25, pulley i9, drive shaft 26 mounted in bearings 27 in frame walls 2d and 29, pulley Sil, belt 3i and pulleys 3?. to 43. The drive unit 22 is driven by the pulleys Sil and 32. to 43 as is brought out below.

The pulleys 32 and 34 drive shafts Si and 52 in the same direction, and the shafts 51 and 52 are journaled in pairs of bearings S3 and 54 mounted in pods 55 and 56 rigidly supported by the trarne wall 29. The shaft 51 is connected and keyed to shaft 57 of a reversing roller subassembly 4S by a coupling 58, and the shaft 57 is journaled by radial-and-thrust bearings 59 and 6i). The hearings 59 and di? are supported in frame arms 6i and 62 rigid on horizontal frame member 63 of the subassembly 43 and rigidly secured to the walls 218 and 29. A regurgitating roller 64 rigid with the shaft 57 has an annular groove 64e and peripheral facings 64d. The facings 64d have lands or collars 64a in facings 64d separated by annular grooves db and 6de. The facings 64d are composed of a known plastic compounds such as, for example, that sold under the trade name Plastisol and the lands have a predetermined frictional coefficient. The facings 64d should have a durometer test of from 65 to The roller 64 is driven continuously in a reverse feed or regurgitating direction, which is counter-clockwise, as viewed in FIG. 5.

The shaft 52 supplies driving power to an electromagnetical actuated clutch 71 (FIG. 7) of known construction, and forming a part of a feed sub-assembly 7i), and when the clutch is actuated drives a driven shaft '72 journaled by bearings 73 in upright frame members 74 rigidly supported by horizontal frame member 75 of the sub-assembly 711. A roller 76 keyed to the shaft 72 has a grooved pulley portion 76C and two friction facings 76d an 76e which have annular lands or collars 76a and annular grooves 76d. The facings '76d are of the same general type of material as that of the facings 64d but are substantially softer than the facings 64d so that the friction coeicient of the lands 76a is much higher than that of the lands 64a. The durometer characteristic of the facings 7 6d should be from about 40 to about 45 to provide the desired frictional qualities. The grooves 64b are staggered relative to the grooves 76h and are directly opposite to the lands 76a and are considerably wider than the lands 76a. Similarly the grooves 76h are directly opposite to the lands 64a and are wider than the lands 64a. The corners or edges of the lands 64a and 76a are relatively sharp, preferably being no greater than ninety degree angles.

A belt 81 is driven by the pulley portion 7 6c, and drives a pulley S2 (FlG. 5) keyed to shaft 553 journaled in the upright frame members 74. A stack of ve dollar bills S4 on edge in a magazine or tray S5 is urged downwardly and to the right, as viewed in FIGS. 3 and 5, by an angular presser S6 slidable by gravity along the bottom of the tray to cause the right hand bill 84 to engage the belt 81 tangentially. When the clutch 71 (FIG. 7) is operative, the shaft 72 is driven counterclockwise, as viewed in FlG. 5, and the belt S1 moves the right hand bill 84 downwardly edgewise into the bite of

therollers

64 and 76. Since the facing 76d has a substantially higher coefficient of friction than the facing 64d, the

Vrollers

64 and 76 move the bill downwardly therethrough even though the roller 64d is driven in the opposite direction. The tray 85 has flanges 85a resting on stepped upper edges 28a and 29a of the frame walls 2S and 29 from which the tray or magazine may be lifted and replaced by another tray identical therewith. Similarly, a tray or magazine 87 identical with the tray S and holding a stack of one dollar bills S8 has flanges 37a resting on upper steps 281; and 291; (FG. 4) of the walls 2S and 29. The

trays

85 and 87 have doors 85h and 871) hinged at their upper ends and forming discharge chutes with guide tongues e and 87C which project down to the roller 64 and a similar roller 39 associated with the tray 87. The doors have clearance slots 85d and 87d for the belt 81 and an identical belt 911.

The reverse rotation of the roller 64 tends to permit only the right hand bill 84 to enter the bite of

rollers

64 and 76 and be advanced therethrough. However, if one or more bills stick. to the right hand bill 34 and be carried into the bite of the

rollers

64 and 76 and be advanced downwardly thereby, the multiple thickness of the bills as they enter between multiple thickness detector rollers 161 and 1452 move the roller 101 to the left sufficiently to cause a lever 193 to actuate a switch 1534. The switch 111/1 then de-energizes the clutch 71 (FlG. 7) to stop the drive of the roller 76 and belt 81. IThe roller 64a then regurgitates the left hand ones of multiple thickness bills back up beyond the bite of the

rollers

64 and 76 and also tends to separate the bills to free the right hand bill. Then, the rollers 1111 and 1192 being freed of the multiple thickness permit the switch 103 to reclose to again make the clutch 71 operative and the left hand bill 84 is fed on through the rollers 1131 and 1122 and along slotted guides 1114 and 1il5 to feed rollers 166 and 1117, the feed roller 1116 being driven by the belt 31 and the roller 107 rotating freely.

The roller 101 is mounted on a lever 16S pivoted on pin 109 carried by a bracket 110 fixed rigidly to the frame member 63. The lever 16S is urged in a counter-clockwise direction, as viewed in FIG. 5, by a wire spring 111 fixed to the bracket 1113 at one end thereof. An adjustent screw 112 carried adjustably by the lever 108 serves to actuate the switch 103.

The

guides

194 and 105 have tongues 14a and 105:1 projecting into annular grooves 1t'i6a and 1l7a in the rollers 1116 and 167, and guide the bill S4 edgewise to the bite of the rollers 166 and 107 just before the bill leaves the bite of the

rollers

64 and 76. The roller 106 then advances the bill on down along flared guide arm 121:1 of horizontal collecting guide or channel 121 to a deflector or separator 122 which deflects the forward edge of the bill downwardly into the collecting guide, where the bill rests on its lower edge with the upper edge extending above the bottom of the separator 122. The arm 121a has stripping lingers 12117 projecting between the lands of the roller 106 and a bracket 123 supporting the vertical separator 122 has stripping fingers 123a projecting between the lands of the roller 167. Supporting bracket members 12315 are secured to the frame walls 2S and 29 to mount the separator on the walls. Brackets 121e` of the collecting guide 121 are fixed to the walls 2S and 29 to mount the guide 121 rigidly on the walls.

After each bill 84 enters the bite of the rolls 106 and 107 so that the feed of the bill by these rolls is started, 'the bill engages a rounded end 131a of a counting feeler or sensing arm 131 pivotally mounted on the frame member 63 and pivots the arm 131 clockwise to open clutch contacts 132 and close counting contacts 133 of the subassembly 43. Opening of contacts 132 de-actuates the clutch 71 (FIG. 7) to stop the feed of the following bill $4 until the bill engaging the counting feeler 131 moves out of engagement with the feeler 131, at which time the counting contacts 133 reopen and the clutch contacts 132 reclose to start the feed of the next bill.

The one dollar bills 3S are fed from the tray S7 toward the collecting guide 121 by a reversing or regurgitating sub-assembly 1411 sub-assembly 48 and a feed sub-assembly 142 identical to the sub-assembly 76. Two pairs of

grooved feed rollers

142 and 143 and 144 and 145, which ,i are identical with but reversed relative to the rollers 106 and 1117, are provided because of the longer path of the one dollar bills. Each of the

rollers

106, 143 and 145 is mounted on a pair of spring-pressed

arms

146, 147 and 148 which urge the

rollers

106, 143 and 145 toward the

rollers

107, 142 and 144.

The sub-assembly 141 includes outboard or balancing feed rollers 151 keyed to shaft 152 mounted rotatably in bearings 153 of upright frame members 154 supported by horizontal frame member 155 which is detachably secured to the

frame walls

28 and 2?. The rollers 151 project through slots 87e in the tray door 87h and engage the front bill S8 and advance it downwardly. The diameter of the rollers 151 is the same as that-of the portion of the belt 9@ on pulley 156. Roller 157 on shaft 15S co-acts with the regurgitating roller 89 to feed the one dollar bills through multiple bill detector rollers 159 and 161?, along slotted guides 161 and 162, to the

feed rollers

142 and 143. The

rollers

142 and 143 feed each bill past counter-feeler 163, which momentarily closes counting contacts 164 and momentarily opens clutch contacts 165, to the

rollers

144 and 145. The clutch contacts 165 actuate clutch 166 (FlG. 6) to momentarily de-clutch the drive of the roller 157 (F1-G. 5) and shaft 152 to space the next succeeding bill S3 back from the bill SS being fed. The

rollers

144 and 145 feed the bill edgewise along flared arm 121e of the collectirlg guide 121 and against `the separator 122 which deflee of the guide 121. As illustrated in FIGS. 3, 5,V 6 and 8, the roller 39, the shaft 153, and the

rollers

142 and 144 are driven by the belt 31 through the pulleys S6, 38, 37 and 4i), respectively.

As illustrated in FIGS. 5 and 8, the collecting channel or guide 121 extends from the frame wall 23 to the frame wall 29, which are identical with one another for convenience of manufacture. The wall 29 has au exit slot the bill downwardly into the right hand portion 22C aligned with the guide 21. to permit a counted stack of the bill (l5 and 88 to be advanced endwise by ejecting

rollers

171 and 172 into a collecting channel 173 having ilared entrance walls 173:1 and 173]), a V-shaped delector 17d deilecting the bills into the channel 173. The roller 171 is driven continuously by a gear 175 keyed thereto, a gear 176 rotatable on post 177, pulley 178, mounted on post 181, belt 179, pulle 12@ keyed to pulley lil-1^; of ejecting mechanism 19d and beveled friction clutch members l2 and 133 keyed to the pulley 1S and the shaft 26. A shaft 184 is mounted rotatably on bellcrack lever 135 and is keyed to both the gear 175 and the roller l71. The lever 185 is pivotally mounted on the post 177 and when pivoted swings the gear 175 around the gear 176. A second bellcrank lever 156 is mounted pivotally on the post 177 and carries the roller 172 on a pin iddo on one arm thereof. When a solenoid winding extending parallel to the guide 12T. is energized, it pulls an armature 88 thereof upwardly, as

viewed in FIG. 8. The armature is connected to the levers E85 and by links 139 and 199 and swings the levers 135' and to move the

rollers

171 and 172 into squeezmg engagement with the stack of bills in the guide- Way 121 and the stack is ejected into the collecting channel 173. The armature 15? normally is spring-pressed toward the position thereof shown in FIG. 8 in which the rollers 71 and 172 are retracted away from the bills in the guideway 12T-t, which has a notch or slot 12M to provide clearance for the

rollers

171 and 172. The solenoid winding la7 is fixed by screws 191 to the base 192 of the irme.

The unit 22 is identical to the unit 21 but is reversehanded relative to the unit 21 and does not include a drive motor. The unit 22 feeds counted numbers of ten dollar bills 2139 and twenty dollar bills from a tray or magazine 271 (FIG. l) to a collecting guide 2%2 and into the collectinU channel 173, which along with the deector 17d, is detachably secured by screws 234 to the wall 29 and an identical wall 223 of the unit 22. Spacers 265 and screws 2% rigidly connect the

units

21 and 22 together in positions in which shafts 2697 having squared ends rit into complementary sockets in the pulleys 3%, 32, 33, 36, 37, 33 and d@ (FIG. 3), the shafts 2%? serving to drive the `feed mechanisms of the unit 22. T he unit 22 also includes an ejecting mechanism 211 (FIG. 8) identical with but opposite handed relative to the ejecting mecha- 1915 oi the unit 21.

The control circuit for selectively determining the amount of currency to be dispensed is shown in FIGS. 9 and l0, and includes the keyboard 23 (FIG. 2). The keyboard includes a hundred dollar key 229 which may be set to cause one one-hundred dollars to be dispensed. The keyboard also includes decade or ten dollar keys 23? to 239, one oi which may be set selectively to cause from ninety to zero dollars to be dispensed as a result of the actuation thereof. Unit or dollar keys 24d to 2559 may be set selectively to cause from aero to dollars to be dispensed as a result or" the actuation thereof. Thus, for example, by setting the keys 22?, 239 and 249, the dispenser will be actuated, when momentary starting switch button 2S@ is depressed, to dispense one-bundred-ninetynine dollars. The range or" amounts dispensed is from one dollar to one-hundred-ninety-nine dollars with the circuit shown, and varies in one dollar increments. Each of the keys when punched or set remains in its set position until released either by pressing an Error key 251 or by pressing an Eject button 252 at the end of a dispensing operation. Also, only one oi the keys 2.3i? to and only one of the keys to 2d? may be set for any given dispensing operation. The interlocking and release structure of the keys is Well known and accordingly is not described in detail.

The chart of FiG. l-/l illustrates the num' er of bills of each of the twenty, ten and tive dollar denominations dispensed in increments of tive dollars for sums of from ve CTI d to one-hundred-ninety-ve dollars, the one dollar bills being dispensed selectively in numbers from zero to four simultaneously therewith. To dispense one-hundred ninety-nine dollars, the

keys

229, 239 and 24@ are set.

key 23d closes contacts 251 to 271 and opens contacts 272 to 27d. The contacts 261 set up a circuit to the 6 terminal of a twenty dollar bill dispensing and counting circuit 279 from each of contacts 23@ to 223 of keys 235 to respectively. Setting of the key 239 closes contacts 2&3, 22E-4l and 2% and opens contacts 226. Closing contacts 283 completes the circuit from one side oi a power source through a motor starting switch 287 (assumed to have been closed manually) to the circuit 279. Closing of contacts 264 and 23d connects that side of the power source to the 6 terminal 223 of a ten dollar dis' ensing and counting circuit 239 to set up the circuit to dispense sit ten dollar bills. Setting of the key closes contacts 291 to 225 and opens contacts 2%. Closing ot` contacts 291 connects power-line conductor 297 to the motor starting switch ..87. Closing contacts 2% connects the power-line conductor 297 to the 4 terminal 22S of a dispensing and counting circuit 2359 to set up the circuit 229 to dispense four one dollar bills. Closing of contacts 225 set up a circuit through the switch 237, contacts 235 and 295 to number 3 erminal of a live dollar bill dispensing and counting circuit to dispense three tive dollar bills.

The dispensing and counting

circuits

279, 289, 299 and Sill. are similar to one another and, for the sake oi' simplicity, only the circuit 279 will be described in detail. The circuit 279 (FIG. 10) may be set by the keyboard 23 to dispense selectively two, four or six twenty dollar bills. When the circuit to the 6 terminal 278 is set up as described above, an and type gating circuit Sii oi a known type is set up. The circuit includes a known bistable multi-vibrator 33.2. The multivibrator 312, when the start key 25@ is actuated, is actuated by a starting pulse from a gate 313 and a known pulse Shaper 31d. This turns the multi-vibrator 312 on to actuate a known relay circuit 3i5 to connect a power-line 31e to a clutch 317. The clutch El? is in tne twenty dollar bill dispensing mechanism of the unit 22, and is identical in construction and operation to the electro-magnetic clutch 71 (FIG. 7) and the clutch 1:55 (FIG. 6). Each time a twenty dollar bill is dispensed from the stack of twenty dollar bilis, the bill being dispensed closes detector or sensing contacts 313 of sensing switch 326 (FIG. l0) corresponding to the contacts 133 (FIG. 5) and opens contacts 319 (FIG 10) corresponding to the contacts 132 (FiG. 5) and in th power-line 31o to the clutch 317. When the contacts 319 are opened, the clutch 317 is thrown out until the bill clears the sensing switch including the contacts 323 and 319, and stops the feed of the next succeeding twenty dollar bill until the bill actuating this switch clears the switch to re-open contacts 31S and re-close contacts 319. Each time a bill closes the contacts 313, a pulse is supplied to a known pulse shaping circuit 322, which shapes the pulse and applies it to a multi-vibrator stage 323 of a known cascaded counter circuit 324 which also includes multi-vibrator stages 325 and 326.

When the stage 323 has been pulsed twice by the dispensing of two twenty dollar bills, the stage 323 supplies a voltage to the circuit 311. However, since the 2 terminal 331 of the circuit 311 is not connected to power at this time by the keyboard 23, the circuit 324 is not actuated to disable the clutch 317. Similarly, when four pulses have been supplied to the stage 323 by the dispensing of four twenty dollar bills, the stage 323 pulses the stage 325 twice and the stage 325 pulses the stage 326 and the circuit 311. However, since the 4 terminal 332 is not connected to power by the setting of the keyboard 323, the circuit 311 is not actuated to cle-energize the clutch 317. As the sixth dispensed twenty dollar bill is dispensed and actuates the switch 320, the stage 323 .7 again pulses the stage 325 which pulses the stage 326 again and the stage 326 pulses the gating circuit 3'1. Since the terminal of the circuit 311 is connected to power by the keyboard .'23, the pulse from the stage 3.756 causes the circuit Sill to pulse the circuit to cut power from the clutch Sl which stops the feed of the twenty dollar bills7 Athe required six having been dispensed from the stack to the intermediate collecting member 333 (FIG. l) of the unit 22 which corresponds to the collecting member tZl of the unit 2l.

While the twenty dollar bills are being selected numbers of ten, five and one dollar bills are dispensed from their respective stacks under control of circuits 239, lifll and 299. The circuit 28% is of a type like the circuit 279 except that the circuit 23? has six multi-vibrator stages 3M to 346 of a l'own ary counter 347 (HG. 13) responsive to counting pulses of sensing or counting switch 348 of the ten dollar bill dispensing mechanism of the unit 22 and known AND gate 349 responsive selectively to pulses from the counter 347. Depending on which of

terminals

233, 35i, 352, 353, 354 or 355 is connected to power by the setting of the keyboard 23, the gate 349 will be responsive to pulses from the stages 346 to 341 of the counter 347, to deenergize clutch 355 of the ten dollar bill dispensing mechanism of the unit 22, the stage 35i pulsing the gate 349 when one ten dollar bill has been dispensed, the stage 342 pulsing the gate 349 when two ten dollar bills have been dispensed and so on until the stage pulses the gate when six ten dollar bills have been dispensed. Assuming only the 6 terminal 2:33 to be connected to power, the contacts 264i and 234 having been set closed, only the pulse from the 6 stage goes through the gate 349 to cause de-clutching of the clutch 356. Thus, six and only six ten dollar bills are fed to the collecting member or chute 333. It is obvious from FlGS. 2, 9, 1l and 14 that the keyboard Z3 also may be set to dispense selectively from one to five ten dollar bills.

While the twenty dollar bills and ten dollar bills are being dispensed, three five dollar bills dii are dispensed to the member or intermediate collecting channel lZl under the control of the clutch '7l (HG. 7) which is controlled by the counter :lill (FiGS. 9 and l2). The counter circuit Sill is the same as the counter circuits 279 and 2239 except that known counter 3e@ has three stages 361; to 363 respectively operable by the first, second and third pulses from counting or sensing contacts f3.3 to pulse AND gate 364. The gate 364 is set by the keys 259 and 249 being set manually to connect orly the 3 contact 391) to power, and gives an output pulse only upon being pulsed by the 3 stage 353 to cle-clutch the clutch 171. When only 2 terminal 3dS is conn cted by the keyboard 23 to power, the gate 364 is actuated on the second pulse so that only two five dollar bills are dispensed. Similarly, when only one five dollar bill is to be dispensed by a setting of the

keyboard

2,3, only a circuit to the l terminal 366 is completed and the first pulse from stage 361 to the gate .3d-4l terminates feed of the five dollar bills after only one has been dispensed.

The one-hundred-ninety-nine dollar setting of the keyboard 23 also requires four one dollar bills to be dispensed. This is accomplished by the contacts 299 being closed by the 9 key 2.429 to connect the 4 terminal 2%8 of AND gate 376 (llG. l3} to the power conductor 297. Known multi-vibrator stages 371 to 37d are provided in known binary counter 375 and are respectively operable to pulse the gate 37 on reception by the counter 375 of first, second, third and fourth pulses from the sensing contacts lo@ of the sensing or counting switch fdl). The circuit being completed to only the terminal 23S and not to 3, 2 and terminals 376, 377 and 373, the gate 37@ is actuated only by the pulse from the stage 37dto de-clutch clutch fdo. The feed of the one dollar bills S from the stack thereof then is stopped after the four one dollar bills have been fed to the channel ll. This brings the total to the channels 1.2i and 2li?. to one-hundred-ninety-nine dollars. Then, when momentary Eject key or button 252 is manually actuated to close contacts 333i and open contacts 332, the eject mechanisms move the forward ends of the bills in the collecting channels 121i and 2532 to accessible positions in tue chute or channel '2.173. The opening of contacts 35.2 resets the

counter circuits

279, 239, 299 and Bill, and also releases the keyboard 2S and the starting switch 25S.
