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. The construction permits the relatively short hot teeth of the first series to contact and transmit heat to the hair while the relatively long teeth of the second series, which are relatively cool, groom the hair and prevent contact of hot teeth of the first series with the scalp during use.
A curling iron comprising a handle, a housing extending from said handle and including an interiorly located heating element, said housing having a longitudinal axis and an outer peripheral cylindrical surface radially spaced from said longitudinal axis, said outer surface including means defining an even number of longitudinally extending grooves, and support bars located in said grooves and each including therealong a plurality of longitudinally spaced teeth extending radially outwardly from said longitudinal axis with the outer ends of said teeth in said rows being spaced from the outer ends of said teeth in adjacent rows at a distance greater than the spacing between said rows adjacent said outer peripheral surface of said housing, said bars being arranged in alternating first and second series, said bars and said teeth thereon of said first series being fabricated of a material having a first heat transmissibility and said teeth thereof having a first radial extent, and said teeth on said bars of said second series being fabricated of material having a second heat transmissibility lower than said first heat transmissibility and having a second radial extent greater than said first radial extent, and an end member removably attached to said housing and including means extending across said grooves for preventing removal of said bars from said grooves.
