Abstract
A hair curling device includes a handle having a front end provided with a socket in which an enlarged cylindrical rear end of an electrically heated hair curling barrel is rotatably mounted. An annular cap-like coupling member secured to the handle couples the barrel rear end in the socket. The barrel is rotated by an electric motor in the handle coupled to the enlarged barrel end by a drive shaft which also carries electrical connection means permitting electric power to be supplied to the heating element in the barrel while the barrel rotates. A pivoted hair clip extends along and parallel to a major portion of the heated barrel and the other end of the barrel is provided with a heat insulating tip member including a radially extending annular portion. Electric power is supplied to the motor and heating element through a power cord connected to the other end of the handle by a swivel connector. Separate switches for controlling the motor and heating element are provided.
