"ONE-WAY CLUTCH FOR AUGER AGITATOR" ' ABSTRACT OF THE DISCLOSURE A vertical-axis, automatic washing machine has a central drive shaft for oscillatably driving a first agitator portion with a clutch member splined thereto. The clutch has downwardly-facing teeth having drive surfaces and slip surfaces. An auger or second agitator portion coaxial with the first agi- tator portion has cooperating upwardly-facing teeth. Upon a drive or forward oscillation of the drive shaft and first agi- tator portion, the drive surfaces engage one another to drive the auger portion in a stepwise rotation. During an opposite rotation of the first agitator portion, the slip surfaces en- gage one another and, where the contents of the washer basket retards a reverse movement of the auger, the teeth will slip past one another, with the clutch member reciprocating verti- cally upon its splined connection. An annular cushioning member placed between the clutch and the agitator parts cush- ions impacts between the teeth during such reciprocations by controlling the depth of tooth engagement. Thus, noise other- wise normally produced during ratcheting of the clutch is sub- stantially reduced.
