Abstract: 892,195. Coin-freed apparatus. GREENWALD, H., WOLFF, L., SILBERGLAIT, H., LAZARUS, H., HAMILTON, G. H., KORN. B., and BERNSTEIN, I. L., [trading as INTERNATIONAL ASSOCIATES.]. Dec. 1, 1959, No. 40776/59. Class 27. Coin-freeing mechanism for timed apparatus, such as a washing machine or drier, comprises a driving plate 56 coin-coupled to an interchangeable driven member 70 having spaced fingers 78 and the position of a coin slot 41 is adjustable relatively to the fingers so that the mechanism can be set to require successive operations by one, two or more coins of the same denomination. The coin slot 41 is provided in a top plate 45 having fingers 43 that pass through slots 28 in a ledge 27 round a housing opening 26 and then engage under the ledge. One or other of two lugs 46 on the plate engage a stem 51 on a key-operated lock 50 to hold the plate in set position. The driving plate 56, on which is a coin-carrier 60, is mounted on a shaft 53 having a control knob 55 and is spaced inwardly from the plate 45 by a number of washers 58 according to the coin size. The driving member 70 is connected by a shaft 71 to a four-lobed cam 85 controlling switches 83, 84 and is above a base-plate 65 having a coin outlet 76 leading to a shoot 75 and coin box 95. A pair of fingers 81 A, 81B on a leaf spring engage the fingers of the driven member to prevent reverse rotation. For one- or two-coin operation, the driving member fingers are spaced 45 degrees apart and the plate 45 is inserted in the opening 26 with the slot 41 pointing towards a dot on a boss 30 and is then turned to align the slot with the figure 1 on the boss and locked by insertion of the stem of the lock 50. Slot 41 is now at 90 degrees from the coin outlet 76 and a single coin inserted will couple the plate 56 and member 70 for 90 degree movement, thus causing the cam 85 to close both switches 83, 84. A solenoid 90 is spring-loaded to hold switch 84 in closed position until at the end of the timed cycle a pulse causes the solenoid to release it. For two-coin operation, plate 45 is inserted with the slot 41 aligned with the dot on a boss 35 and then turned to align the slot with the figure 2. Slot 41 is now only 45 degrees from outlet 76 and two coins and two operations are required to move the cam 85 through the necessary 90 degrees. For three-coin operation, a driven member. 70 having fingers at 30-degree spacings is fitted and the top plate fitted to align slot 41 with the figure 3 on boss 35; three coincoupled movements are then necessary to give the 90 degree movement of the cam. Coin boxes.-The coin box 95 has offset rails 94 fitting in offset tapering tracks 38 in the housing so that the box can only be fitted with a coin inlet on one side in alignment with the coin shoot 75. A handle 97 on the box has a spring finger 98 bearing on the stem of a cylinder lock 105 on a door 100 which closes an opening 36. The door has fingers 103 engaging under a ledge at one side of the door and the lock controls a latch 107 engaging under the ledge at the other side of the door. Preventing fraudulent operation.-The coin carrier 60 is in the form of a channel one leg of which has a bevelled nose 67 that can penetrate the opening in an inserted washer and raise it so that it does not operatively engage the fingers 78. An interchangeable coin tab 47 is is spaced from the fingers so that an oversize coin or one riding on the fingers instead of engaging behind them, becomes jammed and does not operate the driving member. Further, the tab will cut any "pullback" tape secured to the coin.
