Abstract

Tubular hair curlers containing electric heating elements with capped terminals are heated on a support having conductor bars across which the curlers are laid. A series of curlers are heated simultaneously to about 170 F. in 6 to 7 minutes, the heat loss being only about 1* F. per minute while the curlers are in the hair. The caps are made to conduct electric current but are highly resistant to heat transfer. The caps are in the form of metallically coated insulators electrically connected to the heating element terminals through use of a metallized adhesive or a spring clip.

Claims

1. In a hair curler:

an elongated, tubular Body adapted for curling of hair thereabout and provided with end closures;

an electric heating element in said body provided with opposed terminals;

a cap on each terminal extending through a corresponding closure;

each of said caps comprising a nonmetallic tubular member constructed of low thermally and electrically conductive material and being coated internally and externally with an electrically conductive metallic coating; and

said terminals extending into the interior of a respective member and being electrically connected to the metallic coating.

2. The invention of claim 1, each cap having a metallized adhesive electrically connecting the metallic coating on the cap to its terminal.

3. In a hair curler:

an elongated, tubular body adapted for curling of hair thereabout and provided with end closures;

an electric heating element in said body provided with opposed terminals;

a cap on each terminal extending through a corresponding closure;

each of said caps comprising a nonmetallic, tubular member having an external metallic coating and constructed of low thermally and electrically conductive material; and

each terminal having a spring clip of electrically conductive material connecting the terminal with said coating.
