ABSTRACT:
A hair brushing appliance includes a housing, a motor located within the housing, a brush extending from the housing, and a transmission relaying output torque of the motor to the brush. A slippage mechanism associated with the transmission allows the motor to turn, should the brush stop turning such as might occur if the brush snags with long hair in use.
