Abstract A system for heating a hair curler by an electrical device is provided by the present disclosure. The curler is a double-walled roller container filled with a heat-absorbing material and a thermal-conducting material, and the heating device utilizes the principal of resistance heating to rapidly heat the heatabsorbing material until it melts. A temperature sensor automatically turns off the heating device when the curler is sufficiently heated. The curler retains the heat for a relatively long time because of the heat of fusion involved in the transition of state from liquid to solid. The shaping and setting of the hair is accomplished largely as a result of the heat applied during the reshaping of the hair.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
116 words
A hair curling system including a hair curler, comprising: a. a double-walled nonconductive member having a chamber formed between the walls thereof, said chamber containing a heatabsorbing wax substance which is a solid at room temperature and which liquifies at elevated temperatures within the operating range of said substance; b. a pair of metal contacts, one at each end of said chamber; and c. electrically conductive material within said chamber, said material providing a current path between said metal contacts such that said substance can be heated when said contacts are connected to a source of electrical potential, and said material including a carbonlike material dispersed in said wax so as to make said wax conductive.
Claim 2
Dependent Claim
