Abstract
A reversible electric motor supported on a sub-base acts through a reduction gear train to rotate an output shaft supported by a main mounting base, the sub-base being capable of turning through a limited range relative to the main base about the axis of the output shaft. When the output shaft encounters excessive resistance torque in either direction, the sub-base automatically turns relative to the main base and effects the opening of switch means to de-energize the motor.
