COIN ACTUATED MECHANI SM Filed May 9, 1929 Patented May 13, 1930 Unire -I-IENRY L. KISER, OF ADRIAN, MICHIGAN COIN-ACTUATED EECHANISM Application sled May 9, 1929.

This invention relates to coin controlled mechanisms and particularly to a coin controlled mechanism for operating a machine for vending ice as disclosed in my pending application for patent filed of even date herewith.

The general object of the present invention is to provide a very simple and compact means whereby a rotatable member may be actuated by a second rotatable member, the last named rotatable member being adapted to receive a coin, and the coin acting to mesh with the second named rotatable member to thereby cause the actuation of the device.

A further object is to provide a device of this character which is very simple and smooth in its operation, which is not dependent upon complicated combination of springs and slides and in which the coin is readily released after it has done its work.

Another object is to provide a mechanism of this character in which two coins must be deposited before the vending machine or other mechanism may be actuated.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein Figure 1 is a rear face View of a coin mechanism constructed in accordance with my invention;

Figure 2 is a section on the line 2 2 of Figure 1;

Figure 3 is a top plan view of the con struction shown in Figures 1 and 2;

Figure 4 is an inside face view of the coin disk 11;

Figure 5 is an inside face view of the coin disk 12. i

Referring to these drawings, 10 designates a casing disposed within which are the disks 11 and 12. rlhe plate 13 is disposed at the top of the casing and extends over a recess 1()a in the easing equal to the thickness of the disks 11 and 12, this recess being formed to provide the two coin slots 14 and 15, the slot 14 being assumed for the reception of a dime, the slot l5 being also assumed for the reception of a nickel, the slots being of different thickness and different widths so as to Serial No. 361,733.

correspond to these coins. Of course, it will be understood that the slots may be of different cross sectional areas for Coins of dierent dimensions.

The plate 13 is cut away at its lower edge so as to it partially around the disks 11 and 12, these disks being set side by side and in alinement with each other and with their peripheries nearly touching. The disk 11 has two recesses in Yits peripheral face, one 16, having the diameter of half the diameter of a dime, while the recess 17 has a diameter of half the diameter of a nickel. Extending to that margin of the plate 13 which lits along the periphery of the disk 12 is a coin passageway 18. The disk 12 is provided with two semi-circular recesses 19 and 20, the irst recess being adapted to receive the nickel and the second recess being adapted to receive the dime. rlChe disk 11 is cut away upon its pe- Y0 riphery so as to provide two shoulders 21 and 22 and mounted upon the casing and associated with the cut-away portion of the disk is the stop pin 23. The disk 12 is likewise cut away upon its periphery so as to provide two shoulders 24 and 25 and associated with this cut-away portion is the stop pin 26 extending from one wall of the casing. These stop pins 23 and 26 limit the rotation of the disks 11 and 12.

The disk 11 has to have a greater throw than the disk 12 and, therefore, the cut-away portion bounded by the shoulders 21 and 22 is longer than the out-away portion of the disk 12 bounded by the shoulders 24 and 25. S5 The disks 11 and 12 are disposed within the casing and specifically mounted upon the front wall thereof by means of the shafts 27 and 28 which at their rear ends are mounted in the transversely extending strap 29. 0 Mounted upon the shaft 27 on the outside face thereof is a crank handle 30 whereby the shaft of the disk 11 may be rotated.

Mounted upon the shaft 28 on the inside of the casing is an arm 31, the extremity of which is provided with a pin 32 engaging a slot 33 in a link 34. This link 34 is pivotally engaged with a lever 35 which actuates the vending machine as clearly illustrated in my application for patent. When this link 34 is pulled in the direction of the arrow in Figure 1, the trip of the vending machine will be operated and a block of ice will be discharged. Obviously this mechanism might be applied to vending machines for other purposes without any departure from the spirit of my invention. A spring 36 acts to shift the arm 31 to the vertical position shown in Figure 1, the arm in this position being stopped from further movement by the shoulder 24bearing against the pin 26. The coin box 37 has an opening in its top which communicates with the passageway 38 defined by the two walls 39, this passageway being disposed immediately beneath the point of approximation of the two disks 11 and 12. The coin box is, 'of course, provided with any suitable means whereby the coins may be removed therefrom.

The operation of this invention will be obvious from what has gone before. Upon the dropping oi a ten cent piece inthe slot 14 and a five cent piece in the slot 15 and a rotation of the handle 30, the disk 11 will be rotated and will carry the nickel into engagement with the recess 19 and disk 12. The nickel will act like a. tooth in a gear wheel, causing an intermeshing engagement between the disks 11 and 12 which will rotate the disk 12 to a position where the pin 32 is at the end of the slot 3 3. The ten cent piece then intermeshes causing a further rotation of disk 11 and the delivery of the merchandise. When the coin is discharged the spring 36 will bring arm 31 back to initial position. No strain isplaced on the coin at any time during operation.

It, however, a dime has also been inserted, the dime will continue the interlock between the disks 11 and 12 and a further rotation willvbe given by the dime to the disk 12 causing a pull to be exerted upon the rod 34 or link which will actuate the trip of the ice delivering mechanism before the dime also escapes rom between the two disks anddrops into the coin box. As soon as the dime has been dropped, the spring 36 will retract the arm 31. This will in no way affect the disk 11 and, therefore, there will be no kick back to the crank arm 30 las would be the case were the two disks constantly intermeshing with each other.

It will be seen that the coin mechanism which I have described is very simple, that it is very compact and particularly that it `occupies only a very shallow space or casing'. This mechanism provides for the use of two coins of diierent-denomination (or two coins 'of the same denomination as far as that goes) and I iind by the use of two coins, that I secure asmoother and more positive operation than is secured when only one coin isused as a means for interlocking the two 'disks together for common rotation. I do not, however, wish to be limited to the use of a driving disk 11 with two coin recesses and a driven disk with two recesses. Neither do I wish to be limited to the exact construction shown, as obviously many minor changes might be made without departing from the spirit of the invention as defined in the appended claims.

I claim 1.
