United States Patent 3,349,961 VENDING MACHINE HAVHN'G A L0 CK-OUT lVfEANS Ierome Nathan, Manchester, and Thomas H. Croteau, Hartford, Conn, ass'ignors to'The'Seeburg Corporation, Chicago, HL, a corporation of Delaware Filed Sept. 8, 1964, Ser. No. 394,868 24 Claims. -(Cl. 221125) This invention relates to a vending machine and more particularly to mechanism for dispensing vended packaged goods, such as canned or bottled drinks and the like; this machine being-of the type fully shown and described in U.S. Patent No. 3,122,269, dated February 25, 1964.

An object of the present invention is to greatly simplify the mechanism of said machine to materially increase its durability and to reduce its cost of manufacture as well as to render said mechanism much easier to adjust for the sizes of the articles to be dispensed.

Another object is to provide certain improvements whereby the machine is rendered more efiicient in its operation.

A further object is to provide a simplified mechanism for such machines which is more rugged in its construction,.and'therefore less likely to get out of order, and easier to operate.

A still further object is to so position the article being dispensed as to enable the purchaser to more conveniently take hold of it and remove it from the machine.

As shown more particularly in FIGS. 1 and 4, the said vending machine includes a case '5 having a chamber 6 within which is mounted our improved vending unit and suitable related apparatus, such as -a refrigerating unit (not shown). The said case has a front door 7 which is suitably hinged thereto, as at.8.

This invention is particularly adapted for use in machines for vending packaged goods which include a container, such as a can or bottle. In this instance, the machine being illustrated is as used for vending drinks, or like goods, in cans but the same machine may readily be used for vending goods in bottles with only a few minor adjustments required. If desired, the same machine may vend both bottles and cans.

Our improved vending machine comprises a vending unit which has a frame 9 providing front and

back walls

10 and 11 respectively, and a side wall 12. A desired number of dispensing mechanisms are provided in said machine and each of said mechanisms has associated therewith an inclined shelf 13 that is pivotally mounted at 13-a between said front and back walls and is selectively adjust-able for cans or bottles of various diameters by means of supporting bars 14 which are insertable across said front and back walls through a series of elongated holes 15 therein for supporting said shelf in adjusted position.

A chute 16 is provided for storing the cans, indicated at 17., from which said cans will roll onto the shelf 13 as they are dispensed ,by vending operations of the respective vending unit.

Each dispensing mechanism comprises an elongated gate 18, that is cross-sectionally shaped to provide article retaining and blocking portions 18a and 18-h, respectively and disposed longitudinally parallel to said side wall 12. The said gate is pivotally and slideably .mounted in said front and back walls by means of an elongated hub 19 extending through the bearing 20 in the front wall 10 and a shaft 21 which extends through the bearing .22 in the back wall 11 and has an operating lever 23 rigidly connected thereto.

Said shaft 21 is inserted through a hub portion 24 and rigidly secured to the gate by a dowel pin 25 extending crosswise through said hub portion.

The lever 23 has a locking projection 26 which is insert-able through a locking hole 27 in the back wall 11 to lock the gate 18 against rotation when in its normal position and said projection is biased into said hole by a suitable spiral spring 28 which is disposed between the back wall and the end of the gate to bias said gate forwardly into its normal position in said vending unit, as shown in FIG. 5. A push knob 29 is provided on the front end of said gate for manually moving said gate longitudinally against the force of the spring 28 to remove the projection 26 from the hole 27 and thereby permit rotation of said gate for a dispensing operation; the said knob being rotatably mounted in the hub by a shaft 30 to prevent tampering, such as when a person attempts to rotate the gate manually by'forceably tryingto rotate said knob.

All of the gates 18 are retained in their normal and locked position by means of a common operating bar 31 which normally abuts the free ends of the levers 23 to prevent longitudinal movement of the respective gates and thereby retain the projections 26 of said levers in locking position within the hole 27. Said operating bar is vertically slideable on bearings 32 that project from the back wall 11 and have screws 33 threaded thereto which extend through elongated slots 34 in said bar.

As clearly shown in FIGS. 8 to 13, the said operating bar is moveable vertically by a crank 35 on a shaft 36 which is driven by a reduction gear 37 of an electric motor 38 and is connected to the operating bar by a stud 39 extending through a transverse slot in said bar.

Said operating bar is normally disposed in lowered position, as shown in FIG. 10, and is provided with a corner notch 40, for each of the levers 23, and said notches are normally out of register with their respective levers but brought into register therewith to permit longitudinal movement of the respective gates 18 in the manner hereinafter described.

To prevent more than one gate from being moved simultaneously when said notches are in register with the levers 23, there is provided an interlock assembly 41 of the type described in the above referred to patent. Said interlock includes a channel bar 42 on a bracket 43, between which are disposed a plurality of flat wedge-shaped cam members 44, one for each lever 23, and mating bars 45 interposed between said cam members to transfer longitudinal motion to extend the length of the assembly so that the top bar 46 will cause operation of a suitable electric switch 47, herein referred to as a vend switch.

In their normal operative position, all of the

members

44, 45 and 46 lie within channel 48 of the bar 42 and rest upon stationary supporting plates 49 which are disposed in slots 51 in said mating members and secured to the said channel bar 42 and bracket 43 by screws 50. Each cam member 44 has a triangular portion 52 and a projection 53 extending therefrom. The said triangular portion being normally disposed in front of a notch 54 and the projection 53 being normally in register with a notch 55 in the opposite wall of the channel 48 whereby, in their normal position, any of said cam members can be moved laterally by an abutment 56 which is provided on each of the operating levers 23 and is adapted to enter said notch 54 and actuate its respective cam member, when the respective gate is moved longitudinally, to initiate a vending operation of said machine.

When any one of the cam members 44 is actuated and moved laterally, as shown in FIG. 9, its projection 53 enters its respective notch 55 and the said member is thereby locked in that position against upward movement. All

members

44 and 45 below the actuated cam member are then prevented from moving laterally or upwardly and those members above the actuated cam member are moved upwardly thereby, whereupon said cam members will be prevented from moving laterally by being out of register with their respective notches 55. The upward movement of those members above the actuated cam member will cause the finger 57 on the top mating bar 46 to actuate the said vend switch 47.

To prevent fraudulent attempt to actuate one of the cam members 44 without first inserting the required coin, and when the operating bar is in its normal position, by the application of excessive force upon the knob 29 sufficient to bend the respective operating lever 23 against the operating bar 31 and thereby cause operation of the vend switch 47, our invention further provides a stop bracket 58 which extends laterally from said operating bar and is normally disposed above and adjacent to the top mating bar 46 so that said bar cannot be raised until a coin has first been deposited and the operating bar 31 has been moved to its select position as shown in FIG. 11.

A spring 59 is provided to bias all of the

members

44, 45 and 46 downwardly and thus assist them to return to their normal position upon the actuated cam member 44 returning to its normal position.

It will be understood from the above description that initial longitudinal movement of any gate 13 will cause its abutment 56 to move the respective cam member 44 laterally and that, when any one of the cam members 44 has been so moved, all of the remaining cam members are prevented from being moved laterally until the first moved cam member has been returned to its normal position. Thus, the said interlock 41 locks out and prevents operation of all the gates 18 except the one which is first actuated and, at the same time, actuates the vend switch 47 and thereby initiates a vending operation as above described.

To prevent actuation of a gate, when its respective shelf 13 is empty of cans, we provide in each gate a stop damper 60 which is pivoted in the end of the shaft 21 and in a boss 61 within its respective gate and hangs down from said pivotal points so that it swings in the path of the cans entering said gate. A stop 62 is provided on the back wall 11 to engage the inner end of said stop damper while there are no cans within the gate and thereby prevent longitudinal movement of said gate and, consequently, the vending operation of said mechanism for that particular gate. When a can enters the gate, it swings said stop damper out of register with the stop 62, as shown in FIG. 7, and permits longitudinal movement of the gate.

In order to guide the cans into the gates 18 as they roll upon the inclined shelves, there is provided for each gate a cam shaped guide flange 63 which extends inwardly from the front wall 10 and locates said cans inwardly of the front end wall of the gate. The said guide flange is preferably formed by a lancing operation which leaves a hole 64 in the front wall 10 that provides a window through which a user of the machine may observe whether or not a can is contained in vending position within any particular gate. The said hole 64 is supplemented with a hole 65 adjacent thereto to facilitate observation of the cans and the said holes are made to define an arrow pointing to the delivery opening in which the vended cans will be delivered.

To facilitate the removal of a can from the delivery position,

portions

66 and 67 of the front wall 10 are offset inwardly, as shown in FIG. 15, to provide a delivery notch 68 adjacent the side wall 12 and the said front wall portions are cut out at the level of each shelf 13 to provide a delivery opening 69 into which the cans are delivered in position to protrude forwardly from the wall portion 66 so that it will be easy for the customer to take hold of said cams to remove them from the machine. To position said cans to protrude further forward through the opening 69, so that they may be more easily taken hold of, there is associated with each of said holes a deflector bar 70 which is adapted to engage the cans as they roll into delivery position and deflect them forwardly in said opening, as indicated in FIG. 10.

In addition to the vend switch 47, there are also provided a hold switch 71 and a limit switch 72 which are mounted adjacent to the crank shaft 36 and actuated by

cams

73 and 74, respectively, that are mounted on said shaft for rotation therewith.

It is intended that this vending machine shall not be operable until a required coin, or token, has been deposited into a coin controlled mechanism (not shown) through a slot, such as shown at 75 in the front of the machine, and the deposit of said coin is intended to actuate a suitable electric control circuit, such as illustrated in FIG. 19, to condition said machine for the selection of a can from any one of the shelves 13 and to render the machine operative for a vending operation as the selection is made.

Coin operated mechanisms are well known in the art and any suitable form of such mechanisms may be employed to operate an electric switch in said control circuit which is herein called the select switch.

The operation of our improved vending machine will be more clearly understood from the illustration of said control circuit in FIG. 19 of the drawings and is as follows:

As shown, the said control circuit includes a suitable source of electric current through conductors indicated at C1 and C2. Upon the deposit of the required coin in the slot 75, the coin operated mechanism will actuate the select switch 76 and move the blade 77 thereof from its normal position against the contact 78 into engagement with the contact 79 and then return said blade to its normal position. Such engagement of the blade 77 with the contact 79 will establish a circuit between C-1 and C-2 through switch 76, solenoid 80 of the hold relay and switch 84 and energize said solenoids. This will close the switch 81 and keep solenoid 80 energized to retain switch 81 closed after the blade 77 has returned to its normal position against the contact 78. The return of said blade to its normal position will establish a circuit between 6-1 and C-2 through switch 81 select switch 76, hold switch 71 and motor 38 and thereby start said motor and cause rotation of crank 35 which will then raise the operating bar 31 to the select, or gate unlocking, position shown in FIG. 11, wherein its notches 40 are in register with the abutment 82 on the free ends of the respective gate operating levers. As the said operating bar reaches its select position, the cam 73 will open the hold switch 71 to stop the motor 38 and close said switch to the normally open vend switch 47 while the cam 74 will close the limit switch 72 to the switch 85.

At this point of the vending operation, the operating bar 31 will remain in select position until the customer makes his selection and presses the respective knob 29 inwardly for the particular can which he has selected. Pressing said knob inwardly will cause the gate 18, which is retaining the selected can, to move longitudinally and thereby cause the respective abutment 82 on the lever 23 of said gate to enter the respective notch 40 in the operating bar and thus permitthe abutment 56 to actuate the respective cam member 44 of the interlock and thereby raise the top bar member 46 and close the vend switch 47. Closing of said vend switch 47 will establish a circuit between C-1 and C-2 through select switch 76, hold switch 71, said vend switch 47 and a solenoid 83 of a vend relay and thereby energize the said solenoid. This will open switch 84, to deenergize the solenoid 80 and close the

switches

85 and 86. Switch 85 will then establish a circuit between C-1 and C-2 through said switch 85, limit switch 72 and solenoid 83 of the vend relay and keep said solenoid energized. A circuit will then be established between C1 and C-2 through switch 85, limit switch 72, switch 86 and motor 38. Said motor will then rotate crank 36 further and thereby carry the operating bar 31 from its select position, shown in FIG. 11, through the position shown in FIG. 12 and back to its normal position shown in FIG. 10. This movement of the operating bar will rock the lever 23 upwardly and downwardly and thereby also rocking the respective gate to the position of the bottom gate shown in FIG. 7, wherein it will release the selected can 17 and block the following cans, and then return to its normal position, shown by the upper two gates, wherein the following can will enter the respective gate while the vended selected can rolls into delivery position in the delivery opening 69. As the vanded can rolls into said delivery position, it engages the respective deflector bar 70 and is pushed forwardly in said opening into the position shown in dotted lines in FIG. 5, wherein it can be easily taken hold of by the customer and removed from the machine.

During the movement of the lever 23 from the select position shown in FIG. 11, through the position shown in FIG. 12 and back to its normal position, the locking projection 26 on the actuated lever 23 will be biased against the surface of the back wall 11 by the spring 28 and, when said lever is returned to its normal position by the operating bar 31, said projection will snap forwardly into its respective locking hole 27 and thereby lock the respective gate in its normal position.

As the crank 36 reaches its normal position, shown in FIG. 10, the hold and limit

cams

73 and 74 will return their

respective switches

71 and 72 to their normal positions, shown in FIG. 19, whereupon the limit switch 72 will open the electric circuit to denergize the solenoid 83 and return the vend relay to its normal position and thereby complete the vending cycle of operation of the machine.

It will be understood from the above description that, by our invention, we have provided a vending machine which is extremely simple in construction, and therefore very durable and troublefree. Our invention further provides a vending machine which is extremely simple to operate; it requiring simply the deposit of the required coin to condition the machine for a selection by the customer, which he is allowed to do at his leisure. Then, by simply pressing a knob for the particular article selected, the said machine will automatically complete a vending operation and deliver said article in position to be conveniently and easily removed from the machine by the customer.

It is of course to be understood that, while we have disclosed the particular embodiment of our invention illustrated in the drawings, the said embodiment may be modified to a greater or lesser extent without departing from the scope of our invention as set forth in the appended claims.
