Abstract

A clothes washing machine includes a water container, a washing basket rotatably mounted in the water container, and an agitator oscillatable at a bottom of the washing basket. The agitator includes a pulsator plate oscillatable about an axis, and a pulsator rod composed of telescoping members mounted at a center of the pulsator plate for upward extension and downward retraction along the axis during the oscillation of the pulsator plate. The pulsator rod is driven by an inertia body mounted on the pulsator plate such that rotation of the pulsator plate relative to the inertia body in one direction causes the pulsator rod to be retracted downwardly. A spring extends the pulsator rod upwardly during rotation of the pulsator plate in the opposite direction.
