Hair curling implement

Abstract

A steam curling iron is provided with an expansible mandrel carried on the main curling arm of the iron, the mandrel being constituted by a foraminous screen which can be wound and unwound by manually rotatable means to vary the diameter of the mandrel for different size curls. Steam generated within the curling arm is projected through perforations therein to the interior of the mandrel. Treatment liquid or water is metered in discrete quantities to the curling arm from a reservoir within a handle portion in accordance with the operation of a control button. .Iadd.The invention also provides a valve system operated by a button for pumping metered quantities of liquid along the curling arm, and also provides a removable liquid reservoir located in a concealed portion of the handle beneath a closure. .Iaddend.
