2 Claims. 1

This invention relates to new and useful devices for grooming hair and more particularly to a device by means of which curly or unruly hair can be trained and straightened.

One object of the invention is to provide a comb having means for heating the hair.

Another object is to provide a comb heater having a curved surface which in the normal combing actionhas a long sweeping contact with the hair.

Another object is to provide a device which will protect the scalp from being burned while permitting a maximum amount of heat to be applied to the hair. V I

The invention consists in the improved construction and combination of parts to. be more fully described'hereinafter and the novelty of which will be particularly pointed out and distinctly claimed.

In the accompanying drawings to be taken as apart of this specification, there are fully and clearly illustrated several preferred embodiments of the invention, in which drawings:

Figure l is a view of a grooming device including the invention and shown in longitudinal central section, but with certain heating means shown in elevation,

Fig. 2 is a view in section on the line 2--2 of Fig. 1,

Fig. 3 is a view in side elevation of another form of grooming device, but having certain parts broken away to show internal construction, and

Fig. 4 is a detail view in section on the line 44 of Fig. 3.

Referring to the drawings by characters of reference, the numeral I designates a comb member of heat insulating plastic material. The comb member I has a supporting bar or rib 2 which is formed or molded integrally with the hair partingor separating members 3. Each of the members 3 is a ii at tooth in side or end elevation and has an annular or ring-like portion 4 at one end and an elongated projecting portion 5 extending from the periphery of the portion 4 and forming the other end of the members 3. At one end of the comb, there is a supporting member B which is joined to the rib 2 and has a recess or socket I facing the teeth. The aligned apertures 8 through the teeth or hair parting members 3 are of larger diameter than the recess '1. At the other end of the comb there is a terminal tooth member 9 generally similar to the members 3 and joined to the rib 2. The member 9 has a circular projecting flange l0 surrounding its aperturel I. A sleeve supporting member I 2 f ts 2 against the tooth member 9 and is annularly recessed, as at I 3 to fit over the flange ID. The sleeve member l2 and tooth member 9 are bonded or cemented together. At its free outer end, the sleeve member has an internal bearing member, or portion 14 of equal diameter to and aligned with the recess 1. Extending through the comb member apertures 8, there is a tubular supporting rod [6 of metal which fits and is screw-threaded in the recess 1 and which has a sliding fit through the bearing portion l4. The rod I6 is spaced. from the hair parting members 3 by an annular or circular air gap l7. Within the comb mom berportion of the rod l 6,' there is" an electric heating means-which may be a ceramic rod w fitting the tubular rod l6 and having a resistance coil I9 threaded therethrough; The coil I9 is joined to conducting wires 20 which extend through a handle or-hand-grip member 2| and terminate in an electric plug 22. The handle 2i has a conical recess 23 terminating at a shoul-' der 24 and opening into a screw-threaded socket 25. The recess 23 has a clamping fit on a tapered end 26 of the sleeve member l2 onto which it is urged by screw-threading of the socket 25 onto the protruding end 2'! of the rod IS. The shoulder 24 and the seating of the rod end 21 in the base of the socket 25 limit the end thrust on the comb member. The clamping fit of the handle 2| on the taper 26 tightly binds the bearing portion l4 against the rod It so that the comb member is held at both its ends against rotation about the rod [6.

In operation, even though the heating element is plugged-in, there can be a mild heating of the hair, if desired, by using the elongated tooth portions 5 only. However, by using the usual combing stroke a large portion of the circumference of the exposed portion X of the heating rod can be contacted with the hair on each stroke. This is enhanced by the spacing of the supporting rib 2 inward from the periphery of the hair parting members or teeth 3. Since the device is symmetrical, it can be used both right and left handed and also with either face directed toward the scalp for one hand use. The annular tooth portions permit the hair to enter freely to the heating rod, but prevent any possibility of burns to the scalp or hands. The hair parting members are preferably beveled, as shown.

Referring to Figs. 3 and 4, there is a comb member 30 of plastic heat insulating material having a plurality of hair separating members 3! which are of annular or ring-like form in'end elevation, see Fig. 4. The separating members 3| may be joined to, but preferably are formed integral with each other, being the turns of a helix or spiral. At one end, the comb member terminates in a supporting member 32 having a screw-threaded recess 33 therein of less diameter than the bore or aperture through the helix. A tubular supporting member 34 extends from the other end of the comb member in line with the recess 33 and has abearing portion 35 of equal diameter to the recess. 33. Extending through the helix or comb member there is a tubular metal heating rod 36 which is screw-threaded into the recess 33 and projects from the bearin portion 35. The projecting rod end portion 33 is: screwthreaded to receive a handle 31 which has a conical recess which clamps upon the tapered end 38 of the supporting member 34 to tightly clamp the bearing portion 35 onto the rod 36. The rod 36 thus rigidly supports the ends of the comb and holds the separating members spaced by a circular air gap 42 from the: heating rod 35. Within the comb member and fitting in the rod: 36 there is an electric heating means comprising a: ceramic rod 39 having an electric resistance coil 40 threaded therethrough. The coil d3 is connected to conducting wires 41 which extend through the handle 3'1 to a plug as in Fig. 1.. The operation of the device of Figs. 3 and 4 will be apparent from the foregoing description. However, it should be noted that the device is particularly adapted for grooming short hair, long hair being more easily handled with the device of Fig. 1. g

1 Having thus described the invention, what is claimed and desired to be secured by Letters Patent of the United States is:

1. A grooming device comprising an elongated comb member having an aperture extending longitudinally therethrough, said comb member having spaced hair separating members with the spaces therebetween communicating with said aperture, a supporting member rigid with one end of said comb member, an elongated tubular supporting member rigid with the other end of said comb member and having a bearing portion, a tubular heating and supporting rod fixed to said first-named supporting member to rigidly support said one comb member end and extending through said bearing portion, and a handle fixed on the free end of said rod and clamping said bearing portion to said rod to rigidly fix the other end of said comb member to said rod, said rod being of less diameter than the aperture through said comb member and being held by said supporting members in radially spaced relation to said comb member.

2. A grooming device comprising a comb having a plurality of flat hair separating members with aligned apertures therethrough, means joining said flat members to each other with their flat faces in spaced opposition, said means being spaced inward from the periphery of said members, a supporting member carried by one end of said comb and having a recess aligned with said apertures, a tubular supporting member projecting from the other end of said comb and having a bearing aperture aligned with said recess, said tubular member having an external taper at its free end, a heating rod extending through said bearing aperture and seating in said recess, a handle secured on said rod and engaging said taper to clamp said tubular memher to said rod, and electrical heating means for said rod.
