Abstract

283,637. Bingham, J. H., and Glover & Co., Ltd., G. Oct. 13, 1926. Coin action, mechanical-connection and with delivery proportional to value of coin.-In a coinoperated mechanism of the kind in which a coin inserted into a coin pocket in the mechanism engages teeth on a wheel mounted on a vertical spindle and acts as a driving connection, a door is provided to close the edge of the coin pocket remote from the toothed wheel. As shown applied to a gas meter mechanism taking coins of different sizes inserted through a single slot, a coin pocket 9, Figs. 2 and 3, carried by arms 10 fast on a vertical spindle 11 is revolved between an Insertion slot 15<a> and a stop 16 by handle 4 on a spindle 1 which is geared to the spindle 11 through wheels 14, 13. The coin according as it is a penny, shilling, or sixpence engages and drives wheels 22, 23, 24 loose on the spindle. These wheels through gearing of the proper ratio drive a spindle 33 having a wheel 38 which sets forward a screw and nut quantity mechanism. The side of the pocket 9 remote from the wheels 22 - - 24 is formed by a door 25 pivoted at 34. When the pocket meets the stop 16, the door is swung aside to allow the coin to fall to the moneybox. Price-changing mechanism. - The stop 16 is pivoted at 18 to an arm 17 loose on the spindle 11 and has a tail engaging a teeth 19 on a pricechange disc 20. The stop 16 is held in adjusted position by a turn-button 21. Coin-slit closing-devices.-The coin slot 15a is beneath the spindle 1 which has a slot 15 to allow the passage of a coin. As soon as the handle 4 is rotated, the spindle closes the coin slot. The slot is also closed, when the maximum number of coins have been inserted, by a plate 49 actuated by the screw and nut mechanism. Gas, supplying by neler.-The wheel 38 engages a wheel 39 on a spindle 40 splined to a threaded spindle 41 passing through a fixed nut. A disc 42 on the spindle 41 operates the valve lever 43. When the maximum number of coins have been inserted, the spindle 41 by engaging a head 47 thereon moves the spindle 40 to the right so disengaging the wheel 39 from the wheel 38. The wheels 38, 39 are re-engaged, after some gas has been consumed, by a spring 48.
