PROVISIONAL SPECIFICATION.
Improvements in Combs for the Hair and the like.
We OCTAVIUS MARCH of 70 Sinclair Road, Kensington, Electrical Engineer,
and AUGUSTUS WINTERBOTTOM, of Sloane Street, Surgeon, both in the County
of London, do hereby declare the nature of this invention to be as follows:-
:-
This invention for improvements in combs for the hair and the like has for its
object to provide an efficient and ready means for heating the comb so that it shall
dry and frizz the hair and consists essentially in forming the comb of silver or other
metal with its back in the form of a tube, in inserting in the said tube an insulated
electric resistance and in providing the comb with an insulating handle through
which the electric conductors leading to the electric resistance are passed. On
passing an electric current through the resistance it is heated up to the required
temperature and heats the teeth of the comb without then being effected by the
electric current.

Improvements in Combs for the Hair and the like.
We OCTAVIUS MARCH of 70 Sinclair Road, Kensington, Electrical Engineer,
and AUGUSTUS WINTERBOTTOM of Sloane Street, Surgeon, both in the County
of London, do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement :-
This invention for improvements in combs for the hair and the like has for its
object to provide an efficient and ready means for heating the comb so that it shall
dry and frizz the hair and consists essentially in forming the comb of silver or other
metal with its back in the form of a tube, in inserting in the said tube an insulated
electric resistance and in providing the comb with an insulating handle through
which the electric conductors leading to the electric resistance are passed. On
passing an electric current through the resistance it is heated up to the required
temperature and heats the teeth of the comb without them being effected by the
electric current.
In the accompanying sheet of illustrative drawings:
Fig. 1 is a longitudinal section of an electrically heated comb for the hair
constructed according to this invention and Fig. 2 is a cross section of the same.
Fig. 3 is a section of the electrical heater.
The metal comb a preferably of silver has its back in the form of a tube c in
which an insulated electric resistance bis inserted. The comb is provided with an
insulating handled through which the leading in conductors pass.
The nature and amount of resistance employed necessarily varies with the tension
of the current to be used, but must be so arranged that the comb when connected

unduly hot and will maintain such suitable temperature so long as they remain upon
the electric circuit. We find that this is effected by employing a resistance which
absorbs about eight watts for each tube employed, but we do not confine ourselves
to this amount of energy. The resistance 6 consists of a central wire e insulated
by spiral windings f of asbestos and of an outer spiral wire g_surrounding the
central wire and also insulated by spiral windings h of asbestos. The inner ends of
the wires e and 9 are connected together and the outer ends pass through the
handle d. The electric resistance fits within the tube c.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
-claim is :-
1. An electrically heated comb consisting of a metal comb, a metal tube forming
the back of the comb, and an electric resistance within the tube substantially as
described.
2. The improvements in combs for the hair and the like substantially as described
with reference to the drawings.
