Abstract: A domestic clothes washer having a pair of nested tubs one of which is imperforate to retain the washing fluid, the other of which is perforated and rotatable to centrifuge the washing fluid from the clothes being washed thereon. A agitator in the perforate tub is adapted to reciprocate to provide pulsating toroidal circulation of washing fluid. Conventional sequential operating timer means are provided to selectively admit water to the tub to spin the tub and to vertically reciprocate the agitator at normal and slow speeds. A water level pressure switch is provided incorporating an auxiliary switch actuated by a separate cam located on the pressure switch cam shaft whereby the auxiliary switch will automatically override the agitate speed control switch to reciprocate the agitator at a slow speed when the water level within the outer tub is below a predetermined level.

Abstract: A DOMESTIC CLOTHES WASHER HAS A PAIR OF NESTED AND SPACED TUBS ONE OF WHICH (WATER CONTAINER) IS IMPERFORATE TO RETAIN THE WASHING FLUID, THE OTHER OF WHICH (SPIN BASKET) IS PERFORATED AND ROTATABLE TO CENTRIFUGE THE WASHING FLUID FROM CLOTHES BEING WASHED THEREIN. A PERIPHERAL FILL SYSTEM INCLUDES A FILL TUBE CIRCUMSCRIBING THE TOP OF THE NESTED PAIR OF TUBS. THE FILL TUBE HAS SLOTS TO PROVIDE A CIRCUMFERENTIAL SERIES OF SPRAYS, A PORTION OF WHICH ENTERS THE SPACE BETWEEN THE TUBS FOR FLUSHING SUDS THEREFROM PRIOR TO RINSING. THE SIDEWALL OF THE WATER CONTAINER DIVERGES DOWNWARDLY FROM THE CYLINDRICAL SIDEWALL OF THE SPIN BASKET AS AN AID IN FLUSHING SUDS FROM THE SPACE BETWEEN THE TUBS.
