Abstract
A novel ball-type auger ratchet mechanism which may be used with washer agitators and augers. More particularly this mechanism comprises a top cap, a simplified cam, and a plurality of balls. The structures described have fewer parts than conventional auger ratchet mechanisms, and ultimately are easier to assemble and cost less. Furthermore, both embodiments of the instant invention, use mechanical means to achieve a positive locking and non-slipping action, rather that the conventional frictional force mechanisms.
