776,933. Washing tumblers. LAWSON, D. A: H. Oct. 7, 1955 [July 7, 1954], No- 19923/54. Class 138 (1) An apparatus for washing and storing tumblers of the kind comprising a box-like receptacle 1, in which inverted tumblers 4, Fig. 2, are supported to drain dregs therefrom, and a multiplicity of water nozzles 8, 10, for directing water on to the interiors and exteriors of the tumblers, and in which one side of the receptacle 1 is openable (e.g. has a door 2), is characterized by caving a motor 15, Fig. 1, a switch 26 with manually operable means by which it can be closed to supply current to the motor 15, and a cam shaft 17 driven by the motor, the shaft, 17 carrying four arms 18, 19, 22 and 25, the cam 18 controlling a water supply valve 14, the cam 19 operating a detergent pump 20, 21, the cam 22 operating a switch 23 by which hot or dehumidified air is circulated to dry the tumblers after the water supply has been cut off, and the cam 25 operating to open the switch 26 after completion of the cycle of operations; the cams being such that they came into operation in the order given. The receptacle 1 is provided with a hinged door 2 and the bottom is formed of slats or wires 3 to receive the inverted tumblers 4. An inclined floor 5 beneath the receptacle is connected by ducts 6 to a drain. The hot water supply valve 14, Fig. 1, is connected by pipe 13 and branches 13a with upper and lower pipes 11 and 12. The pipe 11 connects with a series of pipes 9 each having a series of nozzles 10, whilst the pipe 12 connects with a series of pipes 7 each having a series of nozzles 8. An air fan in a casing 24, is connected to upper and lower air manifolds 39, 43 of which the manifold 39 is connected by vertical ducts 41 to air inlets at the bottom of the receptacle 1 whilst the manifold 43 is connected by vertical ducts 42 to air outlets at the top of the receptacle the outlets and inlets being in staggered vertical relationship and the ducts 41 being interposed between the ducts 42. The electric motor 15 drives a cam shaft 17 through a reduction gear in a casing 16. The cam 19 controls the movement of a piston 20 in a cylinder 21 of the detergent pump which injects detergent into the hot water stream; the cam 22 controls the closing and opening of the switch 23 in the fan motor circuit; and the cam 25 retains the switch 26 for the motor 15, in closed position after the switch is manually closed by pull-knob 27 and wire 28, Fig. 2, all as described with reference to Figs. 3 to 6 (not shown). In operation the detergent pump only operates after the water valve is opened and stops before the valve closes and the fan motor switch 23 is only closed when the valve is closed. After one revolution of the cam shaft 17 the cam 25 causes the switch 26 to open. Alternate wires or slots 3 may be carried by a frame which is, caused to rise and fall slowly during washing so that the rims of the tumblers are completely washed.
