Abstract

755,636. Coin boxes for coin-freed apparatus. HALL TELEPHONE ACCESSORIES, Ltd. Feb. 9, 1955 [Jan. 20, 1954], No. 1696/54. Class 27 The removable coin box B for a coin collector A has a shutter 3 for closing the coin entrance hole 6 and a rectangular or non-circular section pin 1 of helical or spiral formation is mounted on the coin collector and enters a hole 2 of the corresponding cross-section in the shutter, or in a trunnion 4 carrying the shutter and pivoting it to the lid 5 of the coin box, so that the shutter is rotated by the introduction and removal of the coin box from the collector. A spring toggle 7 is connected to the shutter so as to hold it in the open or closed positions. When the box is withdrawn from the collector, the shutter 3 is rotated into the closed position by the pin and a bell-crank detent 9 engages a tooth 8 on the shutter and holds it closed. When the box is to be emptied, a lock 12 is actuated so that the lid 5 can be removed and the bolt 11 of lock engages a pin 10 on the detent and moves it to a released position in which it is held by another detent 13 engaging behind a lug 9a. When the box is again inserted into the collector, the shutter is rotated to the open position and a cam slot 15 on the trunnion 4 moves an arm 14 to release the detent 13 and allow the detent 9 to move against the tail 3b of the shutter so that it is preset ready to engage the notch 8 when the box is subsequently removed. A safety catch 16 to prevent accidental opening during transit is pivotally mounted at 17 on the shutter and has one end passing through a hole 18 in the trunnion 4 to engage the pin 1 and the other end adapted to engage a notch on a fixed projection 20 on the lid. Specification 612,710 is referred to.
