Curling iron adapted to provide uniform heat when used with either domestic or foreign voltages

摘要

An electric curling iron operative to provide uniform heating at both domestic (120 v) and foreign (240 v) voltages includes first and second rope-type electric heaters disposed side by side in the heatable barrel of the curling iron. The heaters are of the same configuration, coextensive in length with each other and the length of the barrel and are separated from each other by a sheet of electrical insulating material dividing the barrel longitudinally into two compartments each containing one of the heaters. A double throw switch on the curling iron enables energization of the first heater alone at the domestic voltage and both heaters in series at the foreign voltage, the relative resistances of the heaters being selected to produce the same output wattage whether the first heater alone or both heaters are energized. A half-wave rectifier may be provided in series with both heaters and be selectively switchable into and out of circuit therewith to produce high and low heat output rates at either domestic or foreign voltages.
