Abstract: 329,279. Stanton, G., and Greenwall, M. Feb. 13, 1929. Coin action, mechanical-connection. - In a coin-controlled apparatus a coin of the proper denomination inserted in the slot of a member operatively connected to the mechanism of the apparatus engages a retaining projection and a projection on a movable member normally preventing movement of the slotted member, the movable member being displaced by the coin to allow the operation of the slotted member and the movement of the slotted member causing a relative movement of the retaining projection to release the coin. The device shown in Figs. 1, 2, 4, and 5 is for rotating the shaft 11 of a vending or other coin-controlled machine by means of a handle on'the boss 44 of a disc 41. the rotation of the shaft in opposite directions operating different mechanisms. The shaft 11 projects through a face-plate 13 fixed to a bearing plate 12 and is squared to receive a slotted member which is secured to it by a screw 38. The slotted member comprises discs 16, 17, 18, 19 secured together by rivets 20. The coin slot 32 is formed in the disc 18 to which are pivoted rocking levers 21, 25. Normally the levers 21 are held by springs or gravity in a position in which they are not engaged by lugs 42 on the disc 41 when rotated and in which projections 29 engage projections 14 on the face-plate 13 to prevent rotation of the slotted member. A coin passing from the usual shoot into the slot 32 engages against a projection 36a on the lever 25 and projections 34 on the levers 21, and moves the levers 21 outwardly so that the projections 29 are clear of the projections 14 and the ends of the levers 21 lie each in the path of one lug 42 on the disc 41 thereby allowing movement to be imparted to the shaft 11 by rotating the disc 41. On a predetermined angular displacement of the slotted member in either direction the engagement of a pin 31 on the lever 25 with a cam-groove 15 in the face-plate 13 rocks the lever 25 to move the coin-retaining projection 36<a> clear of the slot 32 and allows the coin to fall from the slot. The slotted member and disc 41 are then returned to their normal position by springs. The slotted member may be formed with teeth 54, Fig. 12, engaged by a spring-pressed detent 55 so as to be prevented from returning to its normal position until the disc 41 has returned to its normal position when the detent 55 is depressed by a projection 59. In a modification the slotted member has a single lever 21 only and when the slotted member has been rotated' through a given angle the coin can fall past a fixed retaining-projection. In other forms of the invention the operating handle may be attached directly to the slotted member or may be arranged' to move in a path other than circular. Coin action, multiple coin.-The coin slot may be of such a capacity that the operation of the mechanism is only possible on the insertion of two or more coins, the first coin inserted engaging the retaining projection and the other coins resting on the first coin. The last inserted coin bears against the lever or levers 21.
