Abstract
A dual action agitator for use in a washing machine utilizes a one-way dog clutch having a plurality of dogs made of elastomeric material and pivotally mounted in a cam. The dogs pivot outward to engage an inner surface of an upper agitator barrel to drive the agitator barrel in a first direction during a first oscillatory stroke of a lower agitator skirt, and the dogs pivot away from the inner surface as the lower agitator skirt oscillates in a second opposite direction resulting in unidirectional movement of the agitator barrel to impart additional mechanical motion to a wash load and promote rollover.
