Abstract
A washing machine comprises two frames each mounting a plurality of tubular wash receptacles and arranged to oscillate on a support in opposite directions. Connecting rods resiliently affixed to each frame interconnect the two frames and constitute an oscillating system with the frame and receptacles mounted thereon. A crank drive oscillates the system in the range of the natural frequency thereof. Wash and wash liquid is preferably continuously delivered to each receptacle.
