. 17 Claims.

The present invention relates to dispensing machines, and is more particularly directed toward dispensing machines designed to employ coin releasable mechanism for dispensing one article at a time from any one of a plurality of storage magazines in which the articles are stacked.

According to the present invention, the dispensing machine is provided with a plurality of normally operable devices each interlocked with mechanism adapted to be operated only when a ,coin or other token is present in a predetermined place in the machine. These devices are so arranged that when one initiates the dispensing operation for an article contained in one magazine by manipulating the corresponding device, this operation must be completed and the device returned to idle position. During this entire operation all the devices associated withthe other magazines are locked against operation.

According to the present invention, theplungers for dispensing the merchandise are locked against operation except when a coin or other token is present in the machine. Upon the operation of. any of the. plungers the coin releasable mechanism allows the completion of the cycle of operations in which the plunger is moved to the other extreme position and the article dispensed, all other plungers in the meantime being locked against movement.

According to the present invention, the apparatus is provided with a single operator for shifting the coin to release a latch'mechanisxn, and a plurality of article dispensers are available for actuating this coin shifting operator. When any one of these devices is selected for operation, all others are locked against movement. This single operator is conveniently made in the form of a shaft, and cam means are employed for shifting the shaft.

The invention also contemplates a structure for the purposes herein referred to in which the parts are designed for mass production and ease of assembly of a number of preassembled units.

Other and further objects will appear as the description proceeds.

Reference is made to a continuing application, Serial No. 160,224, filed August 21,1937, directed to the dispensing and cabinet features of the present machine, as distinct from the control mechanism involved in the present application.

The vending machine is provided with a base 20 which, in addition to supporting the structure, I provides certain stationary or flxed parts of'theof the disview on the line mechanism. It has a rearwardly curving upper 35 front face 2| which supports an arcuate trough 22. The trough and curved front wall 2| are concentric. The base member 20 is also provided with upwardly extending posts 23 and 24 near the rear. These posts carry bolts 25 and 26. The 4Q casting forming the base member 20 is also provided with upwardly extending thin plates 21 and 28 forming end walls for the arcuate trough defined by the front wall 2|.

A lower front member 30 is grooved as indicated upper front face of the casting 30 is apertured as indicated at 36 and the base casting 20 is slotted as indicated at 31 to accommodate reciprocatory ejector members 38.

In the drawings, six such ejector members are illustrated. These ejector members are all alike, and each member has a downwardly extending element 39 adapted to be attached to a return spring 40. The front wall 2| of the base member is apertured as indicated at 4| to accommodate the spring 40, and this aperture is closed by the lower portion of the plunger when the plunger is in its inner or normal position, as indicated in Fig. 4. Each plunger is provided with an aperture 42 which, in the normal or inner position of the plunger, is within the annular trough 22 in the base member. The trough receives a number of balls 43 of such size with respect to the length of the trough that one plunger may be pulled out at any one time.

When all the plungers are in the inner position, as shown in Figs. 3 and 4, the balls are loose, but when one of the plungers is pulled out, as indicated in Fig. 8, the web portion 44 of the plunger separates the balls on opposite sides of the plunger and forces the balls into the apertures 42 in the other plungers, thereby locking them against movement.

The inner-ends of the plungers are of T-shaped cross section, as will be apparent from Fig. 12. The webs forming this T overlie the balls. The T-shaped portion is surmounted by a rack 45. The extreme inner end of the plungers is extended downwardly, as indicated at 48, and is provided with a cam surface 41.

The cam surface 41 of the plungers is arranged to engage cam surfaces 49 carried on the upper face of a cam plate 49. This cam plate is secured to a vertical shaft 50 supported on a ball bearing 5| carried by a post 52 secured to the base casting 20. This post also forms an anchorage for the rear ends of the springs 40. When the parts are in the normal position illustrated in Fig. 3, the cams 41 on the plungers are adjacent the camming surfaces 48 on the plate 49. As soon as any one of the plungers 38 is moved outwardly, its camming element engages so as to exert a turning movement to the shaft 50. This is utilized for shifting the coin of the coin-release mechanism in a manner to be'described.

After the base 20, the front-casting 30, plungers 38 and shaft 50 and cam plate are assembled, a cover casting 60 with associated parts may be placed in position above the previously assembled elements. This cover casting is generally of arcuate contour, and its rearwardly extending inner ends 6| and 62 are received on the bolts 25 and 26. Nuts 63 fitted on these bolts fixedly secure the casting 60 in place. This casting is shaped to cover the ball race, as indicated at 64. It is slotted as indicated at 05 to accommodate the T-shaped heads on the plungers 38. The casting 60 is also provided with pairs of spaced bridging members 66 and G7 slotted from underneath as indicated at 68 to accommodate pawls 69. These pawls are held in place by coil springs 10 whose upper ends are anchored to .a curved rod II.

The position of the pawls 69 and the length and position of the racks 45 on the plungers is such that the racks are inside the lower ends 01 the pawls when the plungers are in the-inner position. As soon as the plungers are pulled outwardly beyond an amount to permit testing out slugs, the pawl engages the rack teeth, as indicated in Fig. 11, soas to prevent the return of the plunger until it has been pulled all the way out, as indicated in Fig. 8. The plunger can then be released and the rack will pass by the ratchet and pawl in an obvious manner.

The casting 60 has a bridging member 12 at the rear. This member is slotted at I2 to accommodate the shaft 50. A pedestal 10 havinx uprights I4 and 15 for supporting a coin control mechanismis secured to' this bridging member by bolts 16. The upper ends of the uprights I4 and 15 support a fixed platform-forming member TI which extends forwardly. /It is slotted as indicated at I to permit a coin to drop down into a trough I9 leading to the money box 00. The front end of the platform 11 extends to the right, as indicated at 8| and pivotally carries a pawl 82 pressed downwardly by a spring 03.

The upper end 85 of the shaft 50 is provided with a coin chute 86 adapted to receive a coin C and guide it down into a slot 81 where it rests on top of the plate 11, as indicated in Figs. 4 and 10. The upper edge of the coin is in line with the nose 90 of the pawl 02 so that when a coin is present, the pawl will be lifted by the initial movement of the cam plate 49 in response to the pulling out of one of the plungers 30. The pawl 82 is then raised far enough so that the shoulder 9| is above the stop lug 92 and hence does not interfere with the further movement of the shaft 50. In the absence of a coin C of the proper size, the pawl 02 is not lifted and the plunger cannot be pulled out far enough to have the ratchet 69 engage the rack 45 on the plunger.

The magazines for storing the goods to be merchandized are indicated at 90. These magazines have rear and side walls as shown and open front walls, and are adapted to support stacks of articles such for example as packages of gum indicated at G. The stacks rest on shelves 95 formed in the casting 30. The magazines are secured to the casting 60 by screws indicated at 94.

A follower 98 is placed on top of each stack of articles. It has a downwardly extending foot 91 adapted to enter into a slot 98 in the upper face of the plungers 30 and thereby lock these plungers against movement. This insures that when a particular magazine is empty, one cannot work the machine by starting to operate the corresponding plunger.

The coin control mechanism is supported on the upper end of the upright I4, the parts being secured in place by bolts indicated at I00 and MI. The mechanism has a forwardly extending coin conveying trough formed of a fixed member .I02 and a movable member I02 pivoted on a shaft I03 and held down by a spring I04 wound about the shaft. The pivoted side of the trough forms a scavenger designed to prevent underweight coins, slugs and the like from passing into the coin chute 86.

The movable plate I02 of the scavenger supports a scale I and has a lateral extension I00 engageable with a curved rod I01. This rod I01 is mounted to move with the coin chute 06, as indicated in the full and dot and dash lines of Fig. 7. This movement is brought about by the operation of the dispensing mechanism which turns the shaft 50. During the initial portion of the movement of the shaft 50 permitted by the space between the shoulder 9I on the pawl 02 and the lug 92, the parts move as indicated in Fig. 7,

and this will swing the scavenger to the dot and a,1ss,4sa L for movement thereby when any such plunger is coin, along with any underweight coins or slugs rejected by the scale, will. fall on the shield Ill and be diverted by a plate Ill into acoin return chute III at the left side of the mechanism. This initial movement of the shaft It is accomplished before the pawl it engages the rack on. the plunger and when the plunger is released it will be retracted. by the spring II. The spring I is strong enough to return the connected mechanismio the full line position of Fig. 7. Coins of the proper weight and size will be shifted by the scale Ill down into the coin chute It, as indicated-by the arrows in Fig. 4. Should a coin be present at the lower end of this trough, and another goodcoin pass into the coin chute III, this coin will travel down on top of the coin already in place and be diverted through the open left side of the lower part of the coin chute and fall onto the plate ill so that it is returned.

when the dispensing mechanism is actuated through the complete cycle, the shaft 50 is turned far enough to bring the coin above the slot 18 The camming surface on the inner end of the plunger then passes beyond the cam it on the cam plate and the shaft I0 is not turned thereafter. 0n release of the tension on the ejector or plunger, the corresponding spring 40 returns it to the inner position. As soon as the cam 41 passes by the cam 48, the shaft 50 is restored to normal position by the energy stored up in the spring IN carried by the scavenger. I 4 y The mechanism which has been described is preferably enclosed in a casing such as shown in the drawings. This casing has a rear wall III with the side flanges H2 and H3 received in the lower front casting ii and secured to it by screws indicated at Ill. The left flange H3 supports an upper front member or door H6 by means of a hinge indicated at I". This front member is shaped to be close to the storage magazines and is provided with windows H8 closed by glass plates Ill so that one can observe the stacks of merchandise in themagazines. It is also provided with a coin opening I20. A covermember IN is hinged at I22 to the upper end of the back member and has a flange I23 to overlie the front and side walls. It carries a lock Ill whereby the entire casing may be locked.
