Abstract
A motorized user applied actuator for automobile and like jacks having rotatable operating members for raising and lowering the jack platform, comprising a casing having a drive member detachably cooperable with the jack operating member, and having an electric motor and a unique, compact and lightweight, simple yet highly efficient step-down transmission connecting the motor with the drive member. The transmission comprises a plurality of staged planetary assemblages which effect a great reduction in speed and advantageous conversion of power. In several illustrated embodiments of the invention one or more handles are attached to the motor casing to provide a convenient hand grip. In another form of the invention the hand grip is supplemented by a fitting which separably interlocks with the jack structure to assume the torque on the motor casing. A power cord for the actuator has a plug adapted to be received in the cigar lighter socket of a motor vehicle. In one embodiment the drive member of the actuator has back-to-back elements alternately engageable with the jack operating member to effect a reversal of the jack movement without reversing the motor.
