ABSTRACT:
A two-speed clutch drive system for a multi-speed basket and agitator drive for washing machines, including primary and secondary clutches interposed in series between an input drive shaft and an output member, both mounted concentrically with respect to an inner drum. The primary clutch is a centrifugally-operated system to establish drive between the input shaft and the inner drum, while the secondary clutch establishes drive between the inner drum and the output member. The secondary clutch includes clutch shoes spring-operated to directly transmit the torque to the output during high speed operation. Low speed drive is established by engagement of pivotally mounted auxiliary weights with clutch shoes acting to reduce the engagement pressure with increasing speed, yielding a reduced speed drive through the system by slippage of the secondary clutch. Pivotally mounted triggers control the release of the auxiliary weights and are positioned so as to be struck by a shifter mechanism engagement tab to be rotated to release the weights. Positive stops prevent overtravel of either the triggers or the auxiliary weights during shifting to low speed. The secondary clutch operator springs are mounted to stationary pedestals designed to enable easy installation, while the anchoring of the trigger and weight return springs is to integrally formed bosses, slotted to accept the looped end of the springs.
