Abstract: 341,522. Coin-freed article delivery apparatus. ROSE, H., 177, Victoria Street, BURNS, S., 60, Loraine Mansions, Widdenham Road, Holloway, HEWITT, W. E., 66, Victoria Street, MOSS, P. J., and TURT, H. L., 126, Whitechapel High Street, all in London. Oct. 17, .1929, No. 31575. [Class 27.] Testing coins; coin action, thrust.-In a coinfreed vending machine, the diameter, thickness, and milling of a coin are tested by a number of apertured plates, the apertures of which are brought into registration with one another, when the tests are satisfactory, and permit such movement of a plunger as to bring about the release of latch mechanism controlling access to the goods to be sold. A coin 36, Fig. 6, inserted through a slot 35 raises, against the action of a spring, a hooked plate 37 which is suspended by a pair of links 38 pivoted at 41 to the framework. The plate 37 engages the coin at two points 46, 47, the coin being supported by a pivoted blade 55 which has a knifeedge 56 to engage the milling and is controlled by a coiled spring 58. If the coin is smooth or worn. the blade 55 slips on its periphery and returns to the front of the machine and the coin being unsupported drops down. The diameter is tested by the three-point contact 46, 47, 56 so that, if the coin is of correct diameter, the plate 37 is moved to such a position that an aperture 64, Fig. 7, in a plate 48 carried by it, is in alignment with a plunger 81. The thickness is tested by a pair of levers 69, 70, which are moved apart by the coin and actuate a pair of interconnected levers 73, 74, the lever 74 having an aperture 79 which is brought into registration with the aperture 64, if the coin is correct. An arm 60 provided with an elbow 61 is carried by the spindle of the blade 55, and engages an apertured plate 59 to bring the aperture 65 therein into registration with the apertures 64, 79, when the coin is correctly milled. The plunger 81 is pivoted at 88 to a rocking lever 83, which is pivoted at its middle to a hand-operated spring- controlled plunger 85, and has a hooked lower end 86 engaging the elbow 61. When the plunger 85 is pushed in, the lever 83 rocks about the elbow 61 as a fulcrum, and the plunger 81 moves through the apertures 64, 79, 65. If however, owing to a coin being incorrect, the plunger 81 is blocked by any of the plates 48, 74, or 59, the lever 83 rocks about the pivot 88 and its hooked end 86 forces back the blade 55 to its initial position thereby allowing the coin to drop through a shoot 89, Fig. 12, to be returned to the operator. When the coin is correct, continued movement of the plunger 81 actuates latch-releasing mechanism and a lever 93, which, through a pin and slot connection, moves a coin receptacle 96, Fig. 12, to bring the mouth 97 of this under the coin 36. The blade 55 is carried by the receptacle and moves from under the coin, which is forced by the plate 37 into the passage 97. The levers 69, 70 are carried down by the plate 37 and are opened to release the coin by engaging cam surfaces. Articles stored in separate compartments.-Packets of cigarettes 15, Fig. 1, are stored in compartments 12 of a flat shallow casing 11 and are delivered face first. Each compartment has a false back 16 pressed forward by springs 18, when a door 13 is opened, to push out the packet 15 therein, the movement of the back being limited by guide pins 17, which are arranged so that the movement of the packet, at the side adjacent the door hinge 19, is greater than at the other side. The door is opened by a spring, when a latch 14 having a bevelled nose 32 engaging an eye 33 on the door is released, and is closed by spring-pressed plungers 21 acting on extensions 23 of the door, when the packet is removed. The packet normally holds the plungers out of action by engaging a false side 31 which is connected to the plungers by bell-crank levers 26, 27. The latch 14 is released by a lug 103 thereon coacting with a shoulder 102 on the controlling plunger 81. The latch 14 may be released by a key, when it is desired to fill a compartment, the coin receptacle being moved at the same time to allow a coin to fall out of the machine for collection.
