ABSTRACT:
A drive arrangement is disclosed for producing oscillation of a washing machine agitator and rotation of the basket for the spin cycle. The arrangement consists of a DC motor having an oscillating mode and a unidirectional rotation mode, the motor driving a mechanically shifted transmission, including a planetary gear set driving the washing machine agitator during the oscillation mode of the motor. A gear case is clutched to the washing machine basket during the spin cycle to produce direct drive of the basket during unidirectional rotation of the motor. The transmission shifter arrangement is operated by an incremental rotation of the drive motor which causes a cam follower-shifter member to be axially displaced from a neutral position to produce either a spin or agitate drive condition of the transmission. A dynamic braking arrangement of the washing machine drive motor is provided by switching in a load across motor armature leads to cause braking of the agitator and basket spin whenever the drive motor is not energized.
