Abstract
A single shaft agitate and spin drive for an automatic washer is provided in which a lost motion mechanism or clutch in the form of a plurality of stacked discs is mounted on the agitator shaft, a lower end of the mechanism being driven by the agitator shaft and an upper end of the mechanism driving the basket after a sufficient amount of rotation by the agitator has been inputted to the mechanism. The mechanism absorbs enough rotational motion to allow oscillatory motion of the agitator without transmission of that motion to the basket, but if sufficient rotational motion is input to the mechanism, such as during the spin mode, the mechanism transmits the motion to drive the basket. The amount of rotation absorbed is easily changed by changing the number of discs in the stack.
