Abstract
An electric curling iron includes a handle containing a reversible DC motor for rotating an elongated, generally cylindrical curling mandrel extending from the front end of the handle and coupled to the motor by a clutch so as to prevent injury to the user. The mandrel is electrically heated and controls are provided on the handle for selecting the speed and direction of mandrel rotation as well as the level of mandrel heating. A clamp for releasably retaining a strand of hair is carried by the mandrel for rotation therewith. A manually activated actuating mechanism on the handle is designed to allow opening and closing of the clamp while the mandrel is rotating.
