Thus at the critical time, the scalp is maintained in a cool and comfortable condition, and scalp injury by burning or injury to the hair by excessive heating is entirely avoided.

Although one embodiment of the invention has been herein illustrated and described, it will be obvious to those skilled in the art that various modifications may be made in the details of construction without departing from the principles herein set forth.

I claim:

1. A device for permanent waving of hair, comprising a pair of hinged members constituting a clamp for engaging the hair strands adjacent the scalp preliminary to the curling of the strands and adapted to receive a curling rod, means for locking said members in closed position, a foot for each of said hinged members joined thereto in the base of the clamp, said foot elements being of hollow construction having perforations on the same side and coextensive with the hair engaging faces of the clamp, and said foot elements being closed at one end and having connections with a source of cooling medium at their other end to direct the cooling medium through the perforations against the hair adjacent the scalp.

2. A device for permanent waving of hair, comprising a pair of hinged members constituting a clamp for engaging the hair strands adjacent the scalp preliminary to the curling of the strands and adapted to receive a curling rod, means for locking said members in closed position, a foot for each of said hinged members comprising a rectangular shaped member of fibrous material having a hollow interior closed at one end and open at the other, said members being spaced from the clamping faces of the hinged member to be out of alignment therewith and having perforations on the same side and coextensive with the hair engaging faces of the clamp, and a bifurcated tube having a leg inserted in the open ends of each of said perforated members and having a connection for a source of cooling medium which is adapted to be impinged upon the hair adjacent the scalp through the perforations of the rectangular members.
