The hair curling iron is comprised of a pair of elongated heat conductive semi-cylindrical tubular barrels having an inner flat surface. The barrels have handles and are pivotally connected together whereby the flat surfaces of the barrels may be brought together enclosing hair between. When closed together, the outer shape of the barrels is round, around which the hair is wound to give a curling effect. The size of the barrels, however, is such that the curling iron can not be readily placed in the heating chamber of a conventional curling iron oven. Thus, the instant invention provides for a heat conducting plate having vertical heat conducting rods to be fixed to the top of the oven in heat transfer relationship therewith. The barrels of the curling iron are hollow and open-ended and fit over the heat-conducting rods whereby the curling iron may be heated.Type: GrantFiled: October 9, 1990Date of Patent: February 25, 1992Inventor: Robert J. McGee

Patent number: 4939340Abstract: A curling iron is provided which is easy to assemble and, so, more economical to manufacture. The unit is molded in two snap-together halves, one half being the bottom portion (divided axially) and the other half being the top portion, and a molded spoon. The molded sections would include all the parts except for the electrical components. The curling iron is assembled by inserting the electrical components in one half, snapping the two halves together, and then snapping the spoon into place over the upper half. The molded sections are formed of a high temperature thermoplastic material. This material is transparent to infra-red rays; and, so, if an infra-red heater is used, the rays can pass through the plastic and heat the hair directly.Type: GrantFiled: March 1, 1989Date of Patent: July 3, 1990Assignee: Conair CorporationInventor: Richard H. Brill
