Abstract: 274,227. Graham, S. J. April 26, 1926. Delivery of articles stored in piles; coin action, mechanical-connection.- In a coin-controlled vending machine having means for giving change, the coin, on a forward rotation of an operating handle, is passed through an initial receiving device, where iron and bendable counterfeits are rejected, to a secondary receiving device where it couples two parts together so that, on the reverse rotation of the handle, an article together with change, if any, is delivered and the coin deposited, according to its denomination, in a change magazine or in a money-box. The machine is operable by coins of 5, 10, and 20 cents to sell five-cent articles and is of the type in which articles are piled in magazines in a revolving carrier so that any particular pile can be selected and brought into registry with a fixed delivery shoot. The magazines 5, Figs. 3 and 4, provided with glazed panels 8 are contained in a polygonal casing 4 which rotates about a fixed cylindrical casing 19 and has rollers 13 running .on a track 2. The casing 4 is rotated by handles 16 and the track has notches in which the rollers engage to position a magazine in registry with a delivery shoot 10. The coins are inserted through slots 26 in the cover 23 of the casing 19 and drop to slots 34 - - 36 for 5, 10, and 25 cents respectively in a shaft 32 which on the forward rotation of an operating handle 84 transfers the coins to a hopper 48 having shoots leading to coin pockets formed by pairs of discs 69, 70. The .discs 69 are carried by shafts 59, 61, 63, Fig. 16, geared together by wheels 65 - - 67, and have concentric ribs engaging between similar ribs in the discs 70 which are carried by shafts 60, 62, 64. When a coin is in a pocket, that particular pair of discs are coupled together so that the shaft carrying the disc 70 is rotated on the reverse rotation of the handle 84 to actuate the article delivery and change-giving mechanism, if any. Pawl and ratchet mechanisms 68 prevent reverse rotation of the shafts 60, 62, 64. The handle 84 works between stops 86, 87 and is mounted on a shaft 79 which through bevel gears 80, 81 drives a vertical shaft 75. The shaft 75 through bevel gearing drives the shafts 59, 61, 63 and a shaft 89 having a pinion 90 meshing with a pinion 46 on the coin shaft 32. The pinion 46 also meshes with a pinion 47 on a shaft 44 carrying a plate 43 on to which a proper coin drops to be guided to the hopper 48. The, shafts 60, 62, 64 through bevel gearing drive vertical shafts 93 - - 95 carrying at their lower ends discs 103 - - 105, each provided with an eccentric pin 138 to actuate slides 111 - - 113, Fig. 8, by engagement with cam slots 116 - - 118 therein. The slides are retracted by springs 141 and have at their forward ends pins 131 - - 133 which engage projections 134 or 135 of a depending arm 126, Fig. 4, pivoted at 128 and carrying a spring- faced ejector block 124. This block, when the plate 126 is moved against the action of a spring 145 by one of the slides, pushes the bottom article of a magazine 5 through an opening 11 to the shoot 10. Change-giving apparatus.-Coins of 5 and 10 cents drop from the discs 69, 70 and are piled in tubes 107 to be used as change. Coins of 25 cents drop through a shoot 143 to a money-box 144. The slides 112, 113 are provided with penings 121, 120 respectively to receive 15 and 5 cent pieces and carry them over openings 123, 122 in a plate 77. The coins drop through these openings to an inclined plate 136 so that they are delivered to the shoot 10 together with an article. The slide 112 is actuated by the insertion of 25 cents and delivers two 10 cent pieces as change, the slide 113 being actuated by the insertion of a 10 cent piece and delivering a 5 cent piece as change. The slide 111 which is actuated by the insertion of a 5 cent piece delivers an article only. Testing and diverting coins.-The coins protruding from the shaft 32, Figs. 4 and 17, engage and move aside knurled rollers 37 which are mounted in brackets 38 pivoted at 39 and pressed towards the shaft 32 by springs 40. If a soft disc is inserted it is bent by a roller 37 and does not drop from the shaft 32 until the plate 43 on the shaft 44 has rotated past the position for guiding proper coins to the hopper 48. Such bendable discs are delivered to a hopper 146 and returned to the delivery tray 10 by way of a shoot 149. To prevent iron counterfeits from being delivered to the discs 69, 70, the shaft 32 and its supporting frame is magnetized so that the iron discs do not drop from the shaft 32 soon enough and are guided to the hopper 146 and return shoot 149.
