Abstract: An electric hair curling or styling iron includes an elongated cylindrical housing extending from a handle and enclosing an electric heating element. The outer peripheral cylindrical surface of the housing is provided with an even number of radially spaced longitudinally extending grooves. An elongated support bar is removably located in each of the grooves and each bar includes a plurality of longitudinally spaced teeth extending radially outwardly from the longitudinal axis of the housing. The bars are arranged in alternating first and second series. The bars and teeth of the first series are fabricated from a material relatively of high heat transmissibility, such as aluminum. The bars and teeth of the second series are made of a material of relatively low heat transmissibility, such as plastic. The teeth of the second series are longer than the teeth of the first series.

Abstract: A collapsible electric curling iron includes an elongated hollow handle open at one end and an elongated, generally cylindrical heat conductive housing mounted on the handle for movement between an operative use position where the housing extends out of the handle through the open end and an inoperative storage position where the housing is confined within the handle. A cap on the inner end of the housing cooperates with a collar and guides on the handle to prevent side-to-side or "rocking" movement of the housing in a direction transverse to the longitudinal axis of the handle during movement between the operative and inoperative positions. The housing has a longitudinal bore, generally polygonal in transverse cross section, which accommodates a thin planar electric heating element placed diagonally across the bore and having side edges engaged in diametrically spaced corners of the bore.

Abstract: Disclosed herein is a hair clipper including a housing, a motor located in the housing and including a shaft having a drive member thereon, and a blade set connected to the housing. The blade set includes a lower blade connected to the housing, and a movable blade assembly including a thin planar movable upper blade member and a shoe member including a planar body having a groove formed in its upper surface, a notch therein, and laterally spaced wall portions on opposite sides of the notch and extending upwardly from the upper surface. The movable blade assembly also includes a yoke member secured between the upper surface of the movable blade member and the shoe member, the yoke member including first and second laterally spaced walls extending upwardly through the notch and being engaged by the drive member to cause reciprocating movement of the movable blade assembly relative to the fixed blade.
