  • This invention relates to hair curlers and more particularly it relates to hair curlers with self-contained heating units, which can be heated electrically to its operative temperature quickly, easily and safely, so that the heat is directed to hair exteriorly wound about the curler.
  • Hair curling as practiced today in the home and beauty shops involves division of the hair of the user into various tresses or swatches.
  • Each of the tresses is ordinarily wound uniformly about a hair curler and by dampening the curled tress Iwith water or with chemicals, or applying heat or the like to the tress, the tress is caused to take the form imparted to the hair by the curler.
  • Curlers came in various diameters from about a half an inch to three or four inches in diameter to form the various size curls required by the dictates of fashion or the user.
  • a further object of the present invention is to provide a curler having self-contained heating element which quickly reaches its optimum temperature yabove 212 F., and then automatically shuts off, preventing overheating.
  • a still further object of the present invention is to provide a hair curler having a self-contained heating unit of a predetermined diameter, which can produce a variety of different size curls proportionate to the length of time the tress remains about the heated curler.
