in the art to which exact description of the will enable others skilled it appertains to make and use the same, reference being had to the accompanying draw- Vings, and to the letters and figures of reference marked thereon, which form a part ofk this specification.

This invention relates to new and useful improvements in coin-actuated Vvending mechanism and consists specifically in the provision of a rotatable coin wheel` into which the coins are dropped, an oscillating member being provided for actuation to cause the wheels to make a partial rotary movement, thus `operating the delivery mechanism.

Our invention comprises a simple and efficient apparatus of this nature having various details of construction, combinations and arrangements of parts which will be hereinafter fully described, shown inthe accompanying drawings and then specifically defined in the appended claim.

Our invention is illustrated inthe ac-` companying drawings, in which Figure 1 is a vertical sectional view through a portion of a coin controlled vending machine, showing parts of the invention in elevation.

Fig. 2 is a horizontal cross section showing in top plan view the mechanism illustrated in Fig. 1.

Reference now being had to the details of the drawings by numeral, 1 designates the vending boxing or casing within which is a removable frame 2X in which is journalcd a shaft 2, and 3 is a coin wheel which is fixed to the shaft 2 through the medium of the set screw 4. Saidwheel has an annular slot in its circumference and has lugs 5 projecting from the walls thereof, dividing the annular slot into compartments, each of a suitable size to receive a coin 6 which is deposited therein through the coin chute 7. 8 designates a bail-shaped member which is the shaft 2 and has an offset 9 in one side thereof, as shown clearly in bail-shaped member to assume Anazrtrs. fron vnnmive-naomnns.' r

ing', a lon'gitudirlial ,movement in contract- *eapsain 15 @fait 'sien 1e, and "'17 designates, an, l.head to said plush. rod and .which .is

A =`movable within the enlarged portion ofthe shell 16, and, when at its outer limit, a portion thereof only-projects through the front wall of the box. Said bail-shaped member 8 has a laterally extending wing 18 which is curved and which extends over the coin wheel and end of the bail-shaped member is laterally has a lug 19V which is provided for the purc* `pose of supporting a second coin should it bent as at 20 and is adapted to contact with the lug 19 to limit the tilting movement of the bail-shaped member'in one direction.

Theoperation of our invention Awill be readily understood andis as follows A coin is dropped through the slot 7 into one of the compartments of the coin wheel and, when therein a portion of the coin will project. beyond the circumference of'the wheel 3. to be actuated for the purpose of delivering an article when the operator pushes in upon the head 17. This will cause the stem 14 to contact with the lug 13 and a further inward push upon the head 17 will cause the the position shown in dotted lines in Fig. 1. As its upper end, which `extends over the coin wheel, comes in contact with the edge of the projecting portion of the coin, it will cause the coin to impinge against-one of the lugs 5 andA imparta partial rotary movement to the wheel 3. .This in turn will impart a partial rotary movement to the shaft 2 uponwhich .the coin delivery mechanism,

not shown, 1s mounted and which will cause the article to be delivered. In 'the event of a coin being dropped in the chute afterl 110 The machine isnow in readiness the portion Which extends over the coin Wheel on the lug or the Wing 18 and which Will tend to support the coin until the bailshaped member has returned approximately to its normal starting position, after which the coin will drop into the Slot in the Wheel and the apparatus is reset.

What We claim to bel new is A check-controlled apparatus for vending machines, comprising a frame, a shaft journaled therein and designedV for actuating delivery mechanism, a compartment coin -Wheel fixed to the shaft, a spring-actuated, oscillating bail-shaped member journaled upon said shaft and having portions extending over the edges of said Wheel at points diagonally opposite, one ,side of the member Copies of this patent may be obtained for ve centaeach, by addressing the Washington, D. C.

having an offset, an angled finger fixed to the frame and a coiled spring fastened at one end to said offset and the otherzend to said finger, a push rod mounted Within the frame, and a lug projecting from said member below the offset and positioned in the path of said push rod, a portion ofthe bailshaped member having a link extending over the edge of the wheel.

In testimony whereof We hereunto affix our signatures In presence of two Witnesses.
