Abstract: 575,486. Sinks. MELLOWES & CO., Ltd., COWAN, W. B., and SINCOCK, R. J. E. Aug. 14, 1943, No. 13223. [Class 28] [Also in Groups II, VI, VIII, XXIII and XXIV] A kitchen sink is combined with apparatus for washing and drying dishes and clothes and for cleaning shoes and knives, polishing silver and similar operations. The sink 12, Fig, 1, has an internal pipe 10, fitted at or below its upper edge, provided with inwardly and downwardly directed jet-producing apertures 11 and connected to a pump 14, Figs. 1 and 5, which supplies water under pressure thereto and also connected by a branch pipe 17 to a fan 18 which supplies air under pressure thereto, a motor 32, Fig. 3, being so arranged that it may be coupled to drive either the pump or,the fan. Valves controlling the water pipe and the air pipe are so connected to each other and to the motor control mechanism that on opening the water valve the air valve is closed and the motor coupled to the pump and uncoupled from the fan, and vice versa. An arm 24, Fig. 5, on the spindle of one of the two valves may be connected by links and levers to an axially movable spindle 35, carrying two bevel wheels 36, 37 which may be connected respectively to the fan and the pump through clutches 38, 39, said clutches being alternatively engaged, and the corresponding bevel wheel brought into operative engagement with a co-acting bevel wheel 33 driven by the motor, by axial movement of the spindle carrying them. Water is supplied to the pump from a tank 15, Figs. 1 and 5, fitted in a lateral extension of the sink assembly, said tank being fitted with an immersion heater 16. A rotary drum 69 for washing clothes or a drum for peeling vegetables may be detachably mounted in an auxiliary sink-like compartment 43, between the motor and the sink proper and is connected to a stub shaft 47, Fig. 7, driven by the motor. The stub shaft, for driving at different speeds, is alternatively coupled to a counter-shaft 51 of the motor by a. clutch 56, 57, or is driven by a bevel wheel 58 thereon which is brought into operative engagement with a co-acting bevel wheel driven by the motor. The desired clutch 38 or 39, Fig. 5, is held in the engaged position by an arm 40 of a pivoted lever connected to a rocking lever 41 operatively connected to the movable spindle 35, the other arm 28 of the pivoted lever containing a spring-biased ball, roller, or plunger 29 which co-acts with a base plate 30 on either side of the lever fulcrum 26. A similar device holds the stub-shaft coupled to the counter-shaft of the motor or alternatively holds the bevel wheels in engagement. The motor shaft, or an extension thereof, may be accessible at the front of the assembly and may have a brush 76, Fig. 3, detachably keyed thereon. This brush may be replaced by other brushes for various purposes, or by mops, buffing-spindles, or other labour-saving devices. A drainage receptacle or garbage container 71, Fig. 1, is fitted in an auxiliary sinklike compartment 70. Draining-boards 73, Fig. 6, may cover the compartments 43, 70. Doors 77 close the space below the sink, and a recess 78 is provided below the doors to accommodate the feet of the user. Specifications 558,388 and 562,747, [Group XVII], are referred to.
