ABSTRACT:
A clutch mechanism for the drive system of an automatic washer having a concentrically mounted wash basket, and a motor drivingly connected to the agitator to drive the basket. The clutch mechanism includes a first clutch member drivingly connected to the motor, and a second clutch member drivingly connected to the wash basket and selectively axially actuable for driving engagement with the first clutch member. Opposing engagement surfaces of the clutch members are provided with alternating radially extending splines and grooves having a generally sawtooth profile. The splines of one of the clutch members are provided with squared tips, and the grooves of the other clutch member are provided with squared recesses, so that the shape of the corresponding splines and recesses provide an easily achieved yet secure connection when the clutch members are drivingly engaged. The splines and grooves are so configured to provide clearance for smooth engagement without regard to small variations in tooth size or misalignment, and is such that rattling during steady state spin operation is eliminated.
