(cl: i9.4"'85;):

Cla ms 1'- My ihven'tio'n pertains to coin oontrolledmechanisms; and more particularly to coin controlled manually operated mechanisms which complete a predetermined cycle of operations in response to} theihs'ertionofi a single coin of a predeter mined denomination.

It is an object of my invention to provide a simple c'o'in c'ont'rolledmechanism which is of a rugged construction and which is positive and reliable in operation. 7

It is also-an object of my invention-to provide s'uch a coin controlled mechanism which is readily" adaptable for awidevariety of different uses.

It is a further'object of my invention to provide' a coin controlled amusement and vending ma'ch'ine of improved simplicity and reliability.

Another object of my invention istoprovide an improved coin: retainer;

A fiir'ther object ofmy' invention is to provide an improved dispensing arrangement fcrvendin'g machines.

Further objects and advantages are withinthe scope of the invention; such as relate to, the ar-' rangement, operation and function-of the related elements: of the? structure; to various? details of construction? and to combinations: of parts, elements; pe'r se; and to economies'of-z manufacture andiznunierousi other features as wil1 -be apparent from-a consideration of: the specification in conjunctio'mwith the'drawings disclosing specific em bodiments of theinvention, in which:

1 A tension spring 4| is tensioned between the extended end of the control arm 39 and a stationary anchor pin from the base to normally bias the coin retainerto its coin holding position wherein it is accurately stopped by any suitable stop such as a stop screw or pin 43 rising from the base and abutting the other side of the coin retainer lever.

, When a coin drops into the complementary slots,

between the driving and the driven members, the upper end of the retainer lever 35 catches and holds the coin so that it does not drop entirely I through. As may be seen in Figs. land 3, the

upper end of the retainer lever 35 is provided with a laterally projecting tab 44 the upper edge of which is shaped to a concave curvature, as shown in. Fig. 3, for receiving the edge of the coin l4-and permitting'it to rotate as the driving 1 member i9 is rotatedto apply torque through the coin for rotating the driven member 25. For this purpose the curve in the upper end of the retainer tab 44 is preferably circular with a radius equal to the radius of the coin, about the center of rotation of the members. This tends tocenter the coin when the members rotate instead of sliding the coin backand forth in the slots. Gravity acting on the crank, normally holds the driving 1 member l9 so that its slot is in a proper coin 1 receiving position.

The coin is released by swinging the upper end lines.

tainer lever 35. A chain wheel 5!, which may be any, desired type of chain wheel, is firmly secured f on the shaft in connection with the driven mem ber 25. Actually the driven member 25 may be the hub of the chain wheel "5|, as shown. A see- 0nd rotary driven member comprising a shaft '53 is rotatively mounted in spaced relationbelcw the first driven member on bearings rising from A second chain wheel 56 is secured these are operated simultaneously. One link of ber before the coin is released, depending upon the particular cycle of operations it is desired to accomplish through the coin control mechanism, such as vending, amusements, opening doors or many other purposes, as will be readily understood.

My coin control mechanism may be advantageously utilized for vending by mounting a merchandise storage bin 63 secured to and spaced from the base in a vertical position as by screws 65 through a mounting and spacing bracket 61. As shown in Figs. 1 and 5, the bin is open at the top and the bottom and is preferably formed by bending a sheet of metal to provide side Walls 69 with narrow flanges H turned in together at the front providing an open front slot for convenience in viewing or loading the merchandise in the bin. A dispensing plate 12 is mounted from the base in suitable spaced relation under the lower end of the bin to form an ejection slot of suitable width to pass a single piece or package of the merchandise, such as gum, candy, or the like. A U-shaped dispensing member or fork I3 is supported on the lower end of a dispensing lever 15 which is pivotally supported upon a stationary pivot pin 16 from the base. The dispensing fork 13 has a front arm I! and 'a back arm'l9 suitably spaced to allow a piece of merchandise'to' fall down therebetween and rest uponthe dispensing plate 12. The front arm 11 of the fork normally holds this piece of merchandise so it can not be dislodged by vibrations and caused to slide out. When the dispensing lever 15 swings clockwise, the back arm 19 of the fork pushes the piece of merchandise out through the ejection slot causing it to slide down the dispensing plate 12. To hold up the merchandise in the bin, the back member 59 is provided with a guard 8| extending fromt-he upper edge of this arm of the'fork upwardly and to the right hand side, as viewed in Fig. 1, where it can be seen that the lower end of the bin is at that side cut and bent mat a suitable curvature 82 to'permit the free swinging movement-of the dispensing fork and to properly guide the flow of the merchandise. To operate the dispensing fork [3 it is operatively connectedto the lower end of the coin retainer through a link'83.

" The dispensing plate I2 is curved and inclined downwardly and toward the left hand side to cause an ejected piece of merchandise -to slide down and out for delivery, through a suitable aperture 85 provided in the enclosure 8'! which is shown in position in Fig. 7. A guard plate 89 is mounted under the lower driven member and chain'wheel to prevent insertion of any instru ment through the dispensing aperture in the'en-' 1 the chain 51 carries a projecting catch 59, shown 7 more clearly in Fig. (l, which is carried to engage and move'thefree end ofthe release lever 45, 1 as shown by the arrows,'ju st as a desired cycle of operations'has been completed. This moves the engaged end of the release lever 45 down;

The distance between the two rotatable driven members" and chain Wheels may be selected to 1 p ance-a length. of chain suitable for one, two I or. more complete revolutions of'the driven men closure to engage and turn the chain wheel for dispensing merchandise without the insertion of a proper coin into the coin chute. The enclosure 81 is provided with a long vertical window 92 for viewing' the merchandise through the front slot in the storage bin 63. V

For showing an amusement strip such as a strip of pictures, a roller 93 is provided to rotate with each driven member, as by being'secured upo'n'the hibiting the strip to the'opera'tor as the device is operated. When the exhibition of the strip is completed. the catch 59 on the chain 51 engages a coincollector for receiving and collecting coins deposited for actuating said member, a bracket.

projecting from said base for supporting said coin collector and forming a lock receiving hasp, enclosure means suitable to be installed upon said base for enclosing and protecting said coin collector and the mechanism from unauthorized interference, and said enclosure means having an open area suitable for passing over the lock receiving hasp portion of the'bracket.
