Abstract: 397,770. Coin-freed apparatus &c. AUTOMATIC DRINK CORPORATION, 11, West 42nd, Street, New York, U.S.A. Feb. 7, 1933, No. 3731. Convention date, March 4, 1932. [Classes 27 and 116.] Delivery of liquids.-A coin-freed apparatus for dispensing drinks comprises a flavour supply and a liquid supply, power-driven pumping mechanism for receiving and discharging simultaneously measured quantities of flavour and other liquid and a valve mechanism co-operating therewith whereby the quantities of flavour and other liquid may be fed into a common line which is passed through a temperature control unit and delivered to a cup delivery station. The coin after insertion in a slot in a box 10 corresponding with the particular flavour of drink desired traverses a chute 12. It may in its passage tilt a plate 14 on a rod 16 which carries a mercurv tube 18 and thereby close the circuit of an electro-motor 20 driving shafts 24, 26, 28, or such motor may be run continuously. The coin passes into one of a series of slots 30 in the periphery of a coin disc 32 corresponding to the flavour selected, and mounted on the driven shaft 24, and, as the disc 32 rotates, an adjustable but stationary cam on the shaft 24 moves it outward to tilt a rocker arm 38 on a shaft 40 and couple up the shaft 24 with a cam drive shaft 64 through a one-revolution clutch 52. A shaft 68 is also coupled to the driven shaft 28 by a one-revolutiou clutch controlled by a slotted lever 70 and pin connections from the clutch on the shaft 24 or from the shaft 26, whichever is operated by the inserted coin, but so as to leave the shafts 24, 26 free from one another. The shafts 64, 66, driven from the shafts 24, 26 respectively, carry cams 84, 94 which operate the pistons of pumping cylinders 72, 74 to draw measured quantities of the flavour and other liquid respectively from their supply tanks and deliver them through a piston valve 96 controlled by a cam 104 on the shaft 64 to a common pipe by which the mixture is led through a temperature control unit 108, wherein the drink may be heated or cooled, to a cup delivery station. The bottom cup of one of a number of stacks of nested cups carried on a a plate 116, Figs. 1 and 9, which is rotated step-by-step by a geneva-stop mechanism by gearing 122 on the shaft 68, is stripped by a pair of stripper cams 124, which are casues to pass between the flange of the lowermost cup of a nested stack and the flange of the cup next above, this latter being prevented from dropping when the lowermost cup is released to filling position in a housing 142, by spring controlled hooks 126 actuated by bent lugs 132 engaging with the bent ends 134 of shafts 128. After the cup has been filled, a mutilated gear 148, Fig. 1, engages a rack 149 on a door to the housing 142 to raise the same to permit the removal of the cup. A latch 150 for holding the door in closed position is locked again when the door descends under gravity, with or without a braking action. A trip rod 154 actuated by a cam 158 on the shaft 68 may then be employed to rock the mercury tube 18 and break the electrical circuit of the driving motor.
