(under subclass 222) Subject matter wherein the structure includes electrical heating means adapted to contact the hair or to be used with additional structure to transmit its heat to the hair for the purpose of hair singing.
(1) Note. Since the singeing instruments could be used for cutting, a search should also be made in Class 30, Cutlery. See subclasses 32+ for electrically heated hot wire type hand held razors for fixed or moving hot wire cutters and subclass 140 for cutters in general combined with heater. A claim to a hand held apparatus for cutting hair by an electrically heated wire would be classified in Class 30, Cutlery.
(2) Note. Class 606, Surgery, subclasses 27+, for heat applying surgical instruments, subclasses 32+, for heated surgical instruments which include cauterizers for cutting, sterilizing and coagulation of a wound. These instruments are structurally similar to those instruments found in this subclass and those listed in the search class notes of this subclass.
(3) Note. Class 132, Toilet, subclass 7 will take methods for cutting or singeing the hair on the scalp but this class will not take any instruments which are not specifically adapted for use on the head of a person. See subclass 9 for hair singers specifically adapted for use on a person's head and subclass 118 for hair singers combined with combs.

233+, 236+ or 260+, for similar hand held instruments which utilize a heated wire or other type of electrically heated tip to cauterize, mark, burn or ignite material, or to heat material for soldering purposes. Note the cauterizers in this class are similar to those found in Class 128.
