COIN LOCK FOR ARTICLE DISPENSING MACHINES Filed June 13. 1952 2 Sheets-Sheet 2 IN VEN TOR. THEODORE GEREG/(E ATTORNEY v United States Patent COIN LOCK FOR ARTICLE DISPENSING MACHINES Theodore Cerecke, Cuyahoga Falls, Ohio Application June 13, 1952, Serial No. 293,305
4 Claims. (Cl. 194-61) here or jamb a coin in the usual rotatable coin holding plate, so that said plate may be rotated reversely past 25 a coin-operateddetent. In this manner it has been possible to fix a coin in the holding plate of a vending machine to permit repeated forward and reverse rotation of the operating means including said plate, until the machine has been emptied of its contents, thereby causing considerable loss to the owner of the machine.
One object of the present invention is to provide a simple, inexpensive improvement in a coin lock for vending machines, wherein a coin adhered or jambed in the coin-holding plate thereof will itself serve as stop means to prevent return rotation of the plate.
Other objects of the invention will be manifest from the following brief description and the accompanying drawings.
Of the accompanying drawings:
Figure 1 is a fragmentary front elevation of the improved coin lock, mounted on an article vending machine.
Figure 2 is a rear view of the lock, removed from the vending machine.
Figure 3 is a rear view of the lock with a rear plate of the lock housing removed and showing rotatable coinreceiving and coin-discharging positions, in full and chain dotted positions, respectively.
Figure 4 is an enlarged fragmentary cross-section taken substantially on the line 4-4 of Figure 3.
Figure 5 is a view similar to Figure 3, but with the coin-receiving plate in a partly rotated position.
Figure 6 is a view corresponding to Figure 3, illustrat ing a modified form of the invention.
Figure 7 is an enlarged fragmentary cross-section taken substantially on the line 77 of Figure 6.
Referring to Figures 1 to 5 of the drawings, there is illustrated a coin-lock 10 having the features of the invention incorporated therein, the same being of the type to control dispensation of peanuts, chewing gum, candy or the like from a machine, a portion of which is indicated at 11 in Figure l. The machine, generally, is of the class in which a coin is placed in a slot 12, permitting reciprocable operation a knob or handle 13 on a shaft 14 of operating means (otherwise not shown) to dispense a predetermined quantity of peanuts, for example, the operating means usually including a suitable springpressed device for yieldingly returning the operating means, including shaft 14 and knob 13, to the original Figure 1 positions thereof. That is, the knob 13 is yieldingly turned. approximately 180 degrees to dispense the peanuts in known manner and then released to return to original position, automatically.
r" F F H The lock -10 is contained in a casing 15, including afront plate 16 and a back plate 17 removably securedthereto, as bymeans of's' crews 18, 18. Laterally spaced rib portions 19', 19 on the front plate define with the inner face of the back plate a coin-receiving slot portion 12:: at the upper portion of the lock, which normally registers with a coin-receiving slot or recess 20 in the edge of flat disc or plate 21 keyed on the shaft 14. Arcuate rib portions 22 and 23 on-front plate 16 at laterally opposite sides of the disc 21 similarly define a cavity 24 in which the disc is rotatably received, the lower end of which opens downwardly into :a coin-discharge opening 25 of i the casing 10. A coin C inserted in slot portion 12a of the lock, and into the plate slot 20, is retained between the inner face of the back plate 17 and a Hat surface of an annular rib 26 on the inner face of the front plate.
Angular1y disposed slots 31 and 32 are cut in the arcuate rib portion 22 to receive and retain correspondingly angularly disposed. elongated leaf- spring portions 33 and 34 of a V-shaped member 35 made from a length of spring strip material. Leaf-spring portion 33 extends upwardly--- in the space between the wall 22 and the edge of disc 21,
and a leaf-spring 'por'tion 34' extends downwardly in the continuation of said space. Spring 33 extends to adjacent the coin-receiving slot 12a, as shown in Figures 3 and 5,.
in the path .of'movement'of a protruding edge of a coin C, to press the coin to position fully within'the 'coin slot 20 as disc 21 is rotated in said counter-clockwise direc' tion. Similarly. the spring portion 34 extends to adjacent the discharge opening 25. Intermediate these two retaining springs the rib portion 22 further serves to retain the coin C in place, as shown in Figure 5. In other words,
rotating the disc 21 in counter-clockwise direction, as viewed in Figure 3,. the inwardly projecting end 28.0f
spring 33 (Figure. 2), normally'rides upon the 'outer pe-' riphery of disc '21, but engages the right-hand edge'of the plate slot 20 (see Figure 3) to stop such rotation, unless moved with disc 21 away from the discharge opening '25,
will 'have a rearward or trailing edge portion thereof engaged by said charnfered portion. This results in saidedge of the coin being lifted toward stop engagement with shoulder 39, as shown'in chain-dottedline's in Figure 4,1:
to stop further reverse rotation of disc 21.
In normaloperation of the coin lock 10 shown in Figuresl to 5 in a saidvending machine 11, a coin C is placed in slot portion 12 and allowed to drop through.
The springs 33 and 34serve tokeep the coin'i'n the disc slot 20 as the disc is rotated between the starting and discharge positions. peated as often as coins are placed in slot 12.
Should any dishonest schemejbe utilized, however, "to
This normal operation may berge-Z wedge or-rotherwise adhere a coin in the disc slot '20 with the ideain mind of accomplishing repeatedioperation of the coin lock 10 the same coimthe scheme will be foiled upon thefirst return r tation of so 20, beca' e the trailing edge of the adhered coin will ride up the chamfered end 38 of spring 34, into stop engagement with the shoulder 39 on casing part 17, as shown in Figure 4. In this stop position the free end of spring34 extends in a plane at'a substantial angle to a-line tangent to the point of engagement of the free end of the :spring with the coin. This, of course, prevents further operation of the vending machine until the owner thereof repairs the lock, but it also prevents loss due to repeated operation of the machine on one coin until the machine is empty of articles to be dispensed.
Figures 6 and 7 corresponding to Figures 3 and 4, respectively, illustrate a modified form of coin lock which is in all respects similar to the lock described :above, except that the end of the spring part 34a, of V-shaped spring element 35a corresponding element 35,.is squared at 40 to provide an'i'nner, relatively sharp edg'e-41. Normal operation of this lock is as described above, but upon said dishonest use of the'machine b'y adherence of a coin C1 in disc slot 20a, the sharp edge 40 of the longitudinally relatively stiff spring 34a will diginto the rearward edge portion of the returning coin to prevent return rotation of disc 21a. The angle of the spring with respect to a line tangent to the point of contact of the end of the spring with the-coin is substantially the same as described above in connection with spring 34 in Figure 3. .As before, repair of the lock is required, but the articles in the machine are saved.
Thus, has been provided a very simple, economical device for preventing the aforementioned loss of goods from vending machines, which in the'past created a very vexing. problem for vending machine operators.
Other modifications of the invention may be resorted to without departing from the spirit thereof or the scope of theappended claims.
