United States Patent 3,280,953 PAYOUT DRIVE ASSEMBLY AND CIRCUIT FOR COIN CHANGE DISPENSING APPARATUS Jack E. Bayha, Chesterland, John W. Dixon, Newbury,

and Philip H. Elpiner, Euclid, Ohio, assignors to Transmarine Corporation, Chesterland, Ohio, a corporation of Ohio Filed Mar. 29, 1965, Ser. No. 443,206 12 Claims. (Cl. 194-2) This invention relates to a payout drive assembly and circuit associated with a coin change dispensing apparatus, and more particularly to a unique rack and pinion drive payout assembly with a simple electrical control circuit therefor.

Heretofore, payout assemblies and associated electrical circuitry have been well known in the vending machine art. However, these payout assemblies and circuitry have generally been utilized only for paying out small denominations of coins and for few coins. Hence, solenoid operated payout assemblies have frequently been utilized, where precision operation, quiet and smooth efficiency, and a great reliability were not essential features of the system. However, with the coming of dollar bill changing apparatus, it becomes increasingly necessary to pay out larger denominations of coins, as well as greater numbers, so that the payout apparatus and associated electrical circuitry must be extremely efiicient, yet simple and highly reliable. Systems proposed for this operation heretofore have been susceptible to jamming and have been cumbersome in design, noisy in operation and not particularly reliable. Further, the electrical circuitry associated with such systems have been complex and expensive.

It is the general object of the present invention to avoid and overcome the foregoing and other difficulties of and objections to proir art practices by the provisions of a payout assembly and associated circuitry for a coin change dispensing apparatus which utilizes an essentially conventional coin storage magazine with a slide bar to dispense the coins from the magazine wherein a plurality of parallel racks are operatively connected to the slide bar and driven at a uniform controllable rate to insure a smooth, non-binding movement of the slide bar to effect payout.

A further object of the invention is to provide a slide bar for payout in a conventional coin storage magazine where a plurality of parallel racks are operatively connected to the slide bar which racks are individually driven by pinion gears mounted to a common shaft and driven by a reversible drive motor.

Another object of the invention is to provide a payout control circuit which utilizes snap action limit switches to limit the movement of the slide bar in both directions.

A further object of the invention is to provide a payout control circuit for a double acting slide bar associated with a coin magazine storing coins on both sides thereof which circuitry may drive a coin payout slide bar for payout on one or both sides of the coin magazine according to the actuating denomination, and which circuitry is simple, highly reliable, and requiring very few parts thereby eliminating expense.

A further object of the invention is to provide a payout drive assembly and associated circuitry for coin change vending apparatus which is extremely simple, durable, inexpensive, and highly reliable.

The aforesaid objects of the invention and other objects which will become apparent as the description proceeds are achieved by providing in a coin change dispensing apparatus the combination of a horizontally positioned base frame, a coin magazine having a bottom mounted in spaced relation substantially the thickness of 3,280,953 Patented Oct. 25, 1966 the coins stored therein, said magazine bottom removably mounted on the base frame, a slide bar positioned in the spaced portion between the bottom and the magazine, parallel spaced rack means removably engaging the bar, means to uniformly drive the rack means together in a controlled reciprocating movement to cause the slide bar to push the coins from their position between the bottom and the magazine, and electrical circuit means to control the drive means to the rack means which comprises a toggle switch actuated by the reception of a proper coin, a payout-drive motor actuated by the toggle switch for one way drive, a first snap acting limit switch means actuated by the slide bar to open the circuit to the drive motor to limit the one way movement of the slide bar, a toggle switch actuated by the opening of the limit switch means to reverse the drive motor, and a second snap acting limit switch means actuated by the slide bar to open the circuit to the drive motor and to limit the opposite one way movement of the slide bar.

For a better understanding of the invention reference should be had to the accompanying drawings wherein:

FIGURE 1 is a perspective view of the basic supporting frame and parallel rack and pinion drive apparatus associated therewith without the coin storage magazine;

FIGURE 2 is a front plan view of the apparatus of FIGURE 1 with the coin storage magazine in position;

FIGURE 3 is a side vertical cross sectional view taken on line 33 of FIGURE 2;

FIGURE 4 is an enlarged broken away perspective view of the coin storage magazine showing the relationship of the slide bar therewith;

FIGURE 5 is a schematic wiring diagram of the electrical circuit to operate the drive mechanism shown in FIGURES 1 through 4;

FIGURE 6 is a schematic wiring diagram similar to FIGURE 5, but adapted to only provide a single payout; and

FIGURE 7 is a schematic wiring diagram similar to FIGURE 5, but adapted to only provide a double payout.

While it should be understood that this payout drive assembly and associated circuitry might be utilized with any type of dispensing or vending payout desired, it is partcularliy adaptable to paying out coin change for 25, 50 or dollar bills, and hence it has been so illus trated, and will be so described.

With reference to the form of the invention illustrated in FIGURE 1 of the drawings, the numeral 10: indicates generally a payout drive assembly which comprises a basic supporting frame 12 which supports an upper housing assembly, indicated generally by numeral 14, and a horizontally positioned base frame 16. A coin receiving chute or bucket 18 is operatively mounted to the frame 12 and positioned beneath the base frame 16 so as to extend a considerable distance horizontally on both sides thereof, as better seen in FIGURE 3, in order to receive coins pushed out over both edges 20 and 22 of the base frame 16, as more fully described hereinafter.

In order to receive a coin storage magazine (not shown), the base frame 16 has vertically directed end flanges 24 and 26 which, along with a pivotally mounted top latch 28 removably interlock a coin storage magazine in position on the base frame 16, all in substantially conventional manner.

As an important feature of the invention, a plurality of racks, indicated by numerals 30 and 32, are mounted in parallel relationship to the frame 12 and the base frame 16 so as to be slidable relative thereto. Each rack is operatively driven by an associated pinion gear 30a and 32a, which pinion gears are mounted in fixed relationship to a single drive shaft 38. Each rack 30 and 32 has an elongated driver pin 30b and 32b operatively affixed thereto, and extending through elongated slots 30c and 32c in the base frame 16. As more fully described hereinafter, the pins b and 32b drive a slide bar associated with the coin storage magazine to discharge coins therefrom. Thus, it is seen that rotation of the shaft 38 operatively drives the pins 30b and 32b in a controllably uniform relation along the slots 30c and 32c in the base frame 16.

In order to accurately distinguish when the coins stored in a coin storage magazine have reached the level for replenishment, and to prevent acceptance of coins or bills to actuate the apparatus, a trip arm lever 40 along with associated circuitry 44 may be provided.

FIGURE 2 shows in schematic relation that a single motor may be used to drive the shaft 38. FIGURE 2 also shows a coin storage magazine 52 with a plurality of vertically extending coin chutes 54 operatively associated therewith. Each chute 54 is a substantially cylindrical bore with a small arcuate portion of the bore open to the face of the magazine 52, as clearly illustrated. The coins received in each individual bore 54 are stacked on top of each other and have a greater diameter than the open portion of each bore. from aluminum, and has a contoured milled base 56 which is positioned in spaced relationship from the body portion of the magazine 52 by means of a plurality of spacer washers 58, positioned at the corners, as most clearly seen in FIGURE 4. Of course, it should be realized that suitable milling on the bottom of the body portion of the magazine 52 will accomplish the same purpose as milling the base 56. The washers 58 may be held in position relative to the base plate 56 and the body portion ofthe magazine 52 by suitable means such as screws 60, again as seen in FIGURE 4. The contour milling of the base plate 56, as well as the spaced relationship allows one coin in each chute 54 to be exposed to its full width, as more clearly seen by the coins, indicated generally by numeral 62 in FIGURE 2.

As discussed above, a slide bar 64 is received over the vertically upwardly extending pins 30b and 32b, and is slidably received in the spaced portion between the base 56 and the body portion of the magazine 52. The holes 7 receiving the pins in the slide bar 64 are only of sufficient size to snugly position the slide bar thereover so that a uniform movement of the pins will effect a uniform movement to the slide bar relative to the magazine 52 and the base frame 16. It should be understood that sliding movement of the slide bar 64 by pins 30b and 32b as actuated by the racks 30 and 32 will push each respective coin 62 exposed in each respective chute 54 out and off the edge 20 of the base :frame 16 to be collected in the coin chute 18. With reference to FIGURE 5, it can be seen that the coin storage, magazine 52 contains coin chutes 54 on both faces thereof so that movement of the slide bar 64 either to the left or to the right will effect a coin discharge over the edge 20 or 22 of the base frame 16 and into the chute 18. FIGURE 3 also more clearly shows the relationship of the base 56 to the base frame 16 and the coin storage magazine 52. It should be understood that the base 56 will also have slots similar to the slots 30c and 32c in the base frame 16 so that the pins 30b and 32b may slidably p ass relative thereto. It can also be seen with reference to FIGURE 3 that the slide bar 64 has sufficient width so that upon movement of the driver pins 30b and 32b in either direction, the slide bar 64 will move to a position at least flush with or slightly beyond the outer surface of the magazine 52, thereby insuring that the coins expended fall over the edges 20 and 22 of the base frame 16 and into the coin receiving chute 18. It might be also noted with reference to FIGURE 3, that suitable means, such as angle supports 70 and 72 secured by bolts 74 and 76, respectively, might be used to hold the base frame 16 in position relative to the main frame 12.

In order to limit the movement of the racks 30 and 32 The magazine 52 is generally made and their respective drive pins 30b and 32b and to posi-' tively eliminate jack-potting of the payout, a pair of snap acting limit switches or microswitches and 82, as seen in FIGURE 1, are positioned at each side of the base frame 16 and mounted to the frame 12 by suitable means. A similar pair of switches are mounted on the opposite side of the frame, but are not seen in FIGURE 1 because of the perspective view. In order to effect operation of the switches 80 and 82, the pin 32b has a downwardly extending portion 84 which will engage the arms 80a and 82a of the switches 80 and 82, as clearly shown in FIG- URE 1. The switches 80 and 82 play an important part in the electrical control circuitry for the payout drive assembly primarily to eliminate ja-ckpotting, as will be more fully explained hereinafter.

In order to understand the electrical control circuit for the payout drive assembly, reference should be had to FIGURE 5 wherein a 110 volt source drives into a pair of parallel positioned circuit lines 102 and 104, respectively. The circuit contains four solenoids, indicated generally by numerals 108, 110, 112 and 114, respectively. Plungers 108a through 112a are shown in association with each of the solenoids 108 through 112. The plunger 108a operates a single pole double throw relay switch, indicated generally by the dotted box 116, through the dotted actuation line 108k. The plunger 110a operates a conventional double throw, single pole relay switch 118, as indicated by the dotted actuation line 11%. The plunger 112a operates a single pole double throw relay switch, indicated generally by the dotted lines which controls the direction of rotation of a motor indicated by the dotted lines 122. The single pole double throw relay switches 116 and 120 are of the type which could conveniently be called toggle switches as they snap from one contact to the other upon actuation and remain at the contact to which they have been moved upon deactuation. Whereas, the conventional double throw, single pole relay switch 118 snaps to a closed position upon actuation thereby deactuating the blockout solenoid 114, but snaps back to an open or prevent position upon actuation. The blockout solenoid 114 may be utilized to control a plunger (not shown) to prevent insertion of any denomination of money during the operation of the circuit, or when the power is off, all in a well known manner.

In order to eliminate acceptance of coins when the magazine is empty an out of coin switch, indicated -by the .dotted line 106 is provided in the blockout circuit in a normally closed position, as indicated by solid line 106a. When the coin magazine is empty the switch is moved to the open position, indicated by dotted line 106b to deactuate the blockout circuit.

In order to provide for possible jamming overloads in the circuit, a substantially conventional thermal cut-out, indicated by the dotted block 122, may be provided. In order to simulate the snap acting limit switches 80 and 82 in FIGURE 1, dotted blocks 124 and 126 labeled snap swi ches, are shown in the schematic diagram. This particular circuit has been drawn as illustrating payouts for a 25 insertion, actuating a 25 switch indicated by block 128, and a 50 payout which is actuated by a 50 switch indicated by dotted block 130.

It should be understood before beginning a description of the operation of the circuit of FIGURE 5 that the snap switches 124 and 126 are the type which are normally in one position, and require external physical actuation to switch, but automatically switch back to the normal position when the external physical actuation is removed. Thus, the solid lines 136 and 142 illustrate the usual positions for both switches while the dotted lines 138 and 140 illustrate positions actuated by the. slide bar as driven by the motor 122. i

In operation of the circuit with a 25 coin inserted, the 25 switch 128 closes thereby actuating solenoid 108 to drive plunger 108a to switch the relay 116 from a solid line position 132 to a dotted line position 134. This then completes the circuit for the solenoid 110 which through plunger 110a actuates the switch 118 to open the circuit to the blockout solenoid 114 and prevent the insertion of any further coins until the circuit has been completed. Simultaneously with the above described electrical occurrences, the circuit to the motor 122 has been completed by the movement of the relay 116 to the dotted line position 134 so that the motor drives in one direction until it engages the actuating arm of the snap switch 124 which shifts the switch 124 from its initial position indicated by the solid line 136 to the dotted line position 138, thereby opening the circuit to the motor and completing the cycle. It should be noted that the solenoid 112 is aso actuated as soon as the 25 switch 128 is closed which, actuating through plunger 112a, immediately reverses the direction of rotation through motor 22 by shifting the arm in relay 120. Thus, upon deposit of another 25 piece into the apparatus, the motor 122 will reverse and the same sequence set forth above will take place except that payout will be effected by the slide bar pushing the coins out on the opposite side of the coin magazine, as more fully set forth above. Thus, it is seen that the circuit automatically drives the motor 122 in one direction or the other upon actuation by 25 coin to effect the desired one cycle movement of the motor to achieve payout.

An additional purpose of the circuit is to achieve a two cycle movement of the motor 22 (in other words, in one direction and then back to the original starting position) upon actuation of the switch 130 by a 50 coin insertion. To this end when the switch 130 closes, it immediately actuates the solenoid 112 to drive the plunger 112a and actuate switch 120 to drive the motor 122 in the opposite direction to achieve the first payout.

At the same time as solenoid 112 is actuated, the motor 122 is actuated through either snap switch 124 or 126 since one of the switches 124 or 126 must be in the normal position indicated by solid lines 136 and 142 land the other switch must be in the forced closed position indicated by dotted lines 138 and 140. Suppose that switch 124 is in the normal position indicated by solid line 136 while switch 126 is in the actuated position indicated by dotted line 140. However, as the motor 122 begins to drive the switch 126 is released to its normal position indicated by solid line 142. About the time switch 126 changes the switch 130 has opened again after a momentary built in delay caused by the coin passed therethrough. When this occurs the power supply to the motor 122 shifts through solid arm 132 of switch 116 and through the shifted arm 142 as seen by tracing the circuit.

When the motor 122 drives to the end of the first payout it actuates switch 124 from its normal position indicated by solid line 136 to the doted line position 138. The power actuating the solenoid 112 is actuated again causing it to effectively actuate switch 120 to reverse the mot-or 122 which is still receiving power through its previous supply circuit. Of course, after the second payout is achieved the switch 126 is actuated to the dotted line position 140 to break the power supply circuit to the motor 122.

It should be understood that this circuit will operate substantially the same except in an opposite mannerif the slide bar has been left after a 25 payout in the opp-osite initial position, from that described above. Also, the circuit will operate in this manner described above regardless of the position of the positive acting toggle switch 116 because of a previous 25 payout.

Of course the blockout coil 110 is actuated in the same manner each time to prevent coin insertion during payout.

Thus, it is seen that the unique aspect of this circuit is achieved by utilizing the single pole double throw switches 116 and 120 in combination with the snap acting limit switches 124 and 126 to achieve a single payout when actuated by a 25 coin denomination, and a double payout when actuated by a 50 coin denomination. The solenoid 110 always acts to deactuate the blockout solenoid 114 when the circuit has been actuated by either a 25 or 50 coin. The thermal overload 122 controls the amount of current flow and circuit time operation to prevent darnage to the circuit. The relays 116 and 120 always snap to an opposite contact upon actuation and remain at that contact after actuation. Conversely, the snap switches 124 and 126 snap to a normal position unless actuated externally by the slide bar as driven by the motor 122 thereby eliminating jackpotting of the circuit, whereas the switch 118 snaps to an open position upon actuation and then closes again upon deactuation.

FIGURE 6 discloses a circuit diagram for only a single payout which is substantially the same as FIGURE 5 except that solenoid 108, relay switch 116, and switch 128 have been eliminated from the circuit. To provide a completion of the modified circuit the snap switches 124a and 126a are not connected at their common center poles, but rather the center pole 1261) of switch 126a is connected to the downward pole 1246 of switch 124a. To fully complete the proper current path necessary for operation the downward pole 1266' of switch 126a is connected to the other line 102a of the circuit. One more important change completes the circuit and this resides in switch 124a being switched so that in its normal position (i.e. not actuated by the slide bar driven by the motor) it is in the same downward position indicated by solid line 136a as switch 126a also normally downward as indicated by solid line 142a. This effectively completes the circuit to line 102a when neither switch 124a nor 126a are actuated. Either switch 124a or 126a will be shifted to the dotted line position 138a or 140a. Naturally the coin receiving switch 130a would have to be a delay type, as discussed with reference to switch 130 in FIGURE 5, so the motor 122a might properly reverse and drive away from whichever switch 124a or 126a was closed by the slide bar to allow actuation of the alternate power source before such switch 130a opened.

FIGURE 7 discloses a circuit digaram for only a double payout which is substantially the same as FIGURE 5, except again that solenoid 108, relay switch 116 and coin actuated switch 128 have been eliminated from the circuit. To provide a completion of the modified circuit the snap switches 124d and 126d are connected at their common center poles 124e and 126e while the lower terminal 124 of switch 124d is connected to the other line 1021;. In this situation the slide bar must always start from a position actuating switch 124d to the dotted line position 1381; so that it will snap to the solid line position 136b to provide an alternate power source. The switch of the motor 122b will occur when switch 126d is actuated momentarily breaking the circuit to solenoid 112a. Of course, power to the motor is terminated when switch 124d is again actuated to the dotted line position 138b on the return of the slide bar to its original position. Naturally, the switch 13% receiving the 50 coin must be the delay tape as more fully described above.

Thus, it should be seen that the circuits of FIGURES 6 and 7 provide simple modifications to the basic circuit of FIGURE 5 to provide only single and double payouts respectively. And a particular feature of each modification is that both eliminate the solenoid 108, relay switch 116 and coin actuated switch 128 thus providing a simple, inexpensive modification as desired.

A simple circuit providing great reliability, and yet low cost has been shown to achieve a single or double payout as desired. While this system has been utilized as showing payout for 25 and 50 denominations, it should be understood that any suitable denominations of coins or paper bills could 'be utilized. If paper bills were used their proper authentication would provide signals to actuate the respective switches 128 and 130.

Thus, it is seen that the objects of the invention have been achieved by providing a payout drive assembly with associated circuitry which utilizes a rack and pinion drive for a slide bar in a double sided coin storage magazine to achieve a parallel, controllable and uniform move ment to the slide bar so that payout may be effected on both sides of the coin storage magazine, with the associated circuitry accurately and reliably controlling the movement of the slide bar through a drive motor to effect a single, one directional movement of the slide bar to effect a single payout, with a return of the slide bar to the other side of the magazine to effect a double payout.
