Abstract: 329,299. Brecknell, Munro, & Rogers (1928), Ltd., and Dotman, H. J. Feb. 14,1929. Sale apparatus; coin action, mechanical-connection; multiple coins.-A coin-freed machine permitting a series of actuations of the delivery mechanism for the insertion of a single coin, has a coin-shoot 7 controlled by transversely moving levers mounted on a pair of parallel rock shafts 10, 13, which are actuated by a roller 28' on the delivery drawer 1. The coins pass to the shoot '7 by way of a mechanism 9 comprising through passages for coins of two different predetermined diameters and end-stopped passages to arrest coins of diameters differing from those of the selected coins. The selecting mechanism is provided with a pivoted cover 50, Fig. 7, which is lifted during the initial movement of the drawer thereby allowing rejected coins to be collected or returned to the purchaser. An inserted coin, of smallest diameter for use in the machine, passes through the selecting mechanism 9, into the shoot 7 and rests against a lever 18 on the shaft 10, while supported by levers 24, 25 on the shaft 13. Initial opening movement of the drawer 1 actuates the lever 16, Fig. 4, by means of the roller 28 mounted on the drawer, thereby rocking the shaft 10 and causing the lever 18 to rock the shaft 13 by thrust transmitted through the coin. The actuation of the shaft 13 swings the detent 42 clear of the drawer absument 27 and permits full opening of the drawer. An inserted coin of greater diameter enabling a double actuation of the delivery mechanism to be effected passes through the selecting mechanism into the shoot 7 and rests initially against a lever 17 on the shaft 10, while supported by levers 20, 21 on the shaft 13. On the first opening of the drawer the detent 42 is released by thrust transmitted through the coin in a manner similar to that previously described, but the coin falls only to a stop 36 carried by a lever 32 which is pivoted at 33 to the machine frame and is normally spring urged to obstruct the shoot 7. The lever 32 is moved clear of the shoot by a projection on the inner end of the drawer so that. on the closing of the drawer after the first actuation, the coin drops to a position where it is supported between the lever 18 on the shaft 10 and levers 23, 24 on the shaft 13. At the second actuation of the drawer the coin action is repeated and the coin then falls to the collecting station. The levers 16, 19 on the rock shafts are connected by a spring 29. In a modification in which the coin is stationary during the release of the drawer locking mechanism, independent shoots 57, 58, Fig. 10, are provided for the large and small coins respectively. In this modification the drawer 55 is provided with a pivoted pawl 63 urged clockwise by a spring 65. A small coin, on insertion in the shoot 58 is supported by a ledge 78 on the drawer, and on the draper being actuated, the pawl 63 wipes past the edge of the coin thus causing the free end 63 to swing clear of the locking stop 64. The coin is released and falls to a collecting station when the ledge 78 is withdrawn from under the shoot 58. When a coin of greater value is inserted in the shoot 57 it is supported on a ledge 74 on the drawer for the first actuation of the drawer, a lever 66 pivoted at 67 being moved by a stop 70 on the drawer to obstruct the shoot so that the coin falls only as far as the lever 66 when the ledge 74 is withdrawn from the shoot. The locking stop 63 is withdrawn to allow full opening of the drawer as previously described. The closing of the drawer allows the spring 68 to swing the lever 66 clear of the shoot whereupon the coin falls on to a second ledge 72 carried by the drawer. On the second opening of the drawer taking place a lever 62 mounted on the spindle 60 wipes past the edge of the coin and releases the locking stop 63. The withdrawel of the ledge 72 during the second full opening movement of the drawer releases the coin which falls to the collecting station. Ratchet teeth 79 and 80 may be provided to prevent reversals of the motion of the drawer during the opening and closing movements respectively.
