Abstract: 702,530. Coin freed drink dispensing machines. PEERLESS AUTOMATIC DISPENSERS, Ltd. Oct. 23, 1951 [Oct. 23, 1950], No. 25737/50. Class 27 At each operation of a motor driven coin freed machine a cup is first delivered to an externally accessible opening from a magazine comprising several vertical stacks of nested containers rotated to deliver a cup from one of the stacks, and the cup is then filled with material through a valve operated by a solenoid controlled by a cam-operated switch. Drinking cups. delivering. When a magazine comprising six vertical tubes 9, Figs. 3 and 10, spaced around a column 10 and each containing a column of nested waxed-paper cups is rotated through 60 degrees in the direction of the arrow in Fig. 10 the bottom cup in one column is positively separated from the cup above and falls through a hole 20 in a fixed platform 17 supporting the columns of cups. The remainder of the column from which a cup is delivered is supported by a pair of parallel rails 37, 38 shown in plan in Fig. 5 and engaging beneath a rim on the next-to-bottom cup. Portions 41, 42 of reduced thickness at the ends of the rails 37, 38 engage between the rims of the bottom two cups so that inclined surfaces 43, 44 on the lower faces of the rails prise the bottom cup away from the column. To reduce the pressure on the rails 38 a further rail 46. Figs. 3 and 10, projects through a slot in that tube 9 which lies above the delivery hole 20 to support the upper part of the pile of cups. From the hole 20 the separated cup falls through a shoot 21, Fig. 3, on to a platform 23 where it receives a charge of liquid as described beluw and from which it may be removed through 'an aperture 24. The shaft 11 carrying the assembly of tubes 9 is rotated in steps by a ratchet wheel 25, Figs. 3 and 13, engaged by a roller 26 on the end of a blade spring 27 secured to a rod 28 sliding in the arms 29 of a fixed bracket and reciprocated by a pin 32 which engages in a slot in a yoke 30 on the rod 28 and is mounted eccentrically on a disc 33 fast on one end of the shaft of a geared electric motor 35. Delivery of liquids by time-controlled apparatus. When a cup has been delivered to the platform 23, Fig. 3, it is filled with liquid from a chamber 49 in a tank 4 through an outlet 50 controlled by a. spring biased valve (not shown) which is opened for a predetermined time by a solenoid (not shown) controlled by a micro-switch operated by a timing cam on the shaft of the motor 35. A coin inserted in the machine momentarily operates a switch which causes operation of a selflocking relay which closes the circuit of the motor 35. A cam on the shaft of the motor 35 then closes a further switch which maintains the circuit of the motor for one revolution of the output shaft while a further cam breaks the locking circuit of the relay. A switch operated by the door of the cabinet prevents operation of the machine when the door is open. A drip tray 57, Fig 3, below the platform 23 delivers spilled liquid to a tank 58 which may be slidably removed from the cabinet when the door 2 is opened. Storing liquids. Refrigerating coils 5, Fig. 3, are provided in the lagged walls of the tank 4 and the refrigerator 6 is operated both by a thermostat control and by a further cam on the motor shaft when the machine is operated. A stirrer 7 is also driven during a delivery operation. The machine may however be designed to deliver heated liquids. Indicators. A lamp L. Fig. 3, visible through a window 67 is illuminated while a delivery operation is in progress. Further lamps indicate whether the machine is in service and the nature of the material vended. Insertion of coins in empty or faulty machines,  preventing. Means are provided for preventing insertion of a coin when all the cups in the magazine have been used and when the liquid level in the tank 4 falls to a predetermined level such that sufficient refrigerated liquid remains in the machine to prevent the liquid delivered at the first operation after refilling from being undesirably warm.
