Electrically heated hair curler

Claim 1

An electrically heated hair curler which will uniformly and quickly heat to proper hair curling temperature comprising a hollow-walled cylindrically shaped curler member, means enclosing both ends of said curler member, at least one electrical resistor housed within said curler member for generating heat, a pair of shell members positioned within the curler member for uniformly transferring the heat generated by said electrical resistor to the outer wall of said curler member, each shell member being constructed of heat conducting material and comprising a cylindrically shaped outer wall conforming to the shape of the curler wall arranged in intimate contact with the curler wall, an inwardly extending cavity defined by inwardly projecting edges of said shell for accommodating therein at least a portion of said electrical resistor, said pair of shell members arranged in endto-end relation within said curler member so that said cavities are aligned and abut each other so as to form a single cavity for housing therein the entire electrical resistor, said resistor being in thermal contact with the inwardly projecting edges defining the cavity of said shell members so that the heat generated by said resistor is transferred to the outer wall of said shells, a sleeve member extending from opposite ends of said resistor longitudinally through each of said shells for carrying therethrough lead wires of said resistor, said lead wires being in electrical contact with said sleeve Members, electrical terminals connected to the ends of said sleeve members and extending externally of both opposite ends of the curler member for connection to a source of electric current, and a plurality of finger-like projections extending outwardly about the periphery of the cylindrical shaped curler member for engaging strands of hair to be curled.
