Abstract: 402,471. Coin-freed liquid-dispensing apparatus. TUDHOPE, K. M., Lome Cottage, Auchamore Road, Dunoon, Argyllshire. June 6, 1933, No. 12697 /32. [Classes 27 and 106 (v).] In coin - freed beverage - dispensing apparatus of the type comprisingaliquid-measuring device and cupescapement mechanism associated with a cup magazine containing a stack of cups adapted to be released singly on actuation of the measuring- device, the liquid measuring and delivery mechanism comprises a plug-cock incorporating separate measuring-chambers adapted to be put into communication with tanks containing liquids to be dispensed in one position of the plug, so as to receive measured quantities of the liquids by way of separate ports in the plug, and to be put into communication with a common outlet port in the plug in a second position of the plug for delivery of the measured quantities of liquids. The apparatus comprises a water tank 2 with float-controlled supply, a tank 3 for flavouring &c. liquid, a glass magazine 4 containing a stack of waxed-paper cups 5, and a liquid-measuring device comprising a cock having a ported plug 6, Figs. 1 and 4, which is rotatable, by a handle 7, within a cock body 8 having inlet branches 9, 10 connected by pipes 11, 12 respectively to the tanks 2, 3. Formed in the cock body 8 are two measuring chambers 13,14 having glazed windows 17,18 and normally communicating with the branches 9, 10 through ports 15, 16 in the plug 6. By rotating the handle 7, the ports 15, 16 are moved out of register with the inlet branches 9, 10, and a longitudinal channel 19 in the plug 6 is brought into register with ports 13<1>, 14<1> to discharge the contents of the chambers 13, 14 through an outlet 20 at the base of the plug 6. The chambers 13, 14 are provided with vent pipes 21, 22. Carbon dioxide or other gas may be admitted automatically to the water tank from a cylinder by means of a spring-loaded valve opened by a member moving with the cock plug. The magazine 4 is provided with a drying-agent 46. Delivery of articles stored in piles.-Actuation of the cock handle 7 is adapted to effect release of the lowermost cup 5 by means of a transverse slidable shutter, which has two pairs of tongues, one pair normally supporting the stack of cups, and the other pair being engageable with the second lowermost cup to support the stack when the shutter is actuated to release the lowermost cup, a closure slide 34 being simultaneously opened by a wire 33 against a spring 35 to allow the cup to pass down a shoot 36 to filling position. The shutter is actuated by a plunger 26, which is pressed inwards against a spring by a pivoted lever adapted to be engaged by a cam 28 on the plug 6. Coin action, weight; coin-discharging mechanism.-The coin-freed mechanism comprises a coin shoot 37 terminating above a disc 38 on the plug 6, the disc 38 being notched and engaged by a spring-urged detent adapted to be released by the engagement of the coin with a feeler, to permit actuation of the handle 7. In the liquid-release position of the cock, a slot in the disc 39 registers with the shoot 37 to allow the coin to drop into a receptacle. The disc 38 is toothed to cooperate with a detent adapted to ensure a full stroke of the handle 7.
