7 Claims. 1

This invention relates to improvements in hairtreating implements for accentuating or restoring waves in growing hair or hair assembled in strands and curls in the ends of hair assembled in strands, such as wigs. waves and/or curls in hair are either natural or are induced by winding the strands upon suitable supports or by the application of heat by suitable means or by treatment with chemicals, or combinations of the above means.

It is also well recognized that no comb or brush when operated by a translatory motion longitudinally of the strands will of itself induce or accentuate waves and curls but upon the contrary will straighten the hair when treated by such translatory longitudinal movement alone.

It is well known that One of the objects of the invention is to provide a hair-treating implement adapted to be so manipulated as to provide a combined translatory and rotative movement which when passed through the hair or strands of hair will enable the residual elasticity of the hair to induce or restore waves therein and curls at the ends thereof.

Another object of the invention is to provide a device of this character having a handle so constructed as to be comfortably grasped and readily manipulated to produce a combined longitudinal and rotative movement as it is passed longitudinally in the strand of hair to accomplish the purpose above described.

Another object of the invention is to provide a hair-treating implement of the character described in which the hair-engaging elements can be rigidly assembled radially and preferably symmetrically with respect to the axis of the handle.

A further object of the invention is to provide a construction in which the hair-engaging elements can be readily and detachably assembled upon the handle.

These and other objects and features of the invention will more fully appear from the following description and the accompanying drawings and will be particularly pointed out in the claims.

Preferred embodiments of the invention are illustrated in the drawings, in which,

Fig. 1 is a view of a rotatable comb;

Fig. 2 is a view of the .end of the head of the comb shown in Fig. 3 and showing six hairengaging combs radially assembled with respect to the extended longitudinal axis of the comb handle;

Fig. 3 is a vertical sectional view of the comb illustrated in Fig. 1 showing a modified form of cap on the end of the shank, a portion of the handle being broken away;

Fig. 4 is a vertical sectional view on line 4-4 Fig. 1;

Fig. 5 is a view of a comb embodying the invention in which one or more brushes are radially interposed between adjacent radially disposed combs; and,

Fig. 6 is a vertical sectional view on line 66 Fig. 5 showing three radially extending brushes interposed between successive radially extending combs.

The invention as embodied in Figs. 1-4 inclusive comprises a series of six combs assembled radially with respect to the axis of the handle of the comb with means detachably clamping the combs in assembled position upon the handle, but it will be understood that any suitable number of combs or brushes may be thus assembled and clamped together and to the handle in axial relation thereto, the handle preferably comprising flat faces corresponding in number to the number of hair-engaging elements of the hair-treating elements.

As illustrated in Figs. 1 to 5 inclusive each of the combs comprises a back I with radial parallel comb teeth 2. The back of each comb has symmetrically converging

flat faces

3 and 4 adapted when assembled to position the combs radially with respect to the axis of the handle. Each of the combs is provided at its outer end with a large substantially triangular tooth 5 and at its inner end with another enlarged tooth 6 and having 2. preferably converging extension 1 adapted to enter and fit a socket 8 in the end portion of a handle 9, as illustrated in Fig. 3. The combs preferably, but not necessarily, are of thermoplastic material and means are provided for detachably clamping the combs in assembled position upon the handle.

Any suitable means may be provided for thus clamping the combs in assembled position. In the constructions illustrated herein the clamping means comprises a star shaped head cap 10 having an annular rabbet ll adapted to engage a complementary recess in the end teeth 5 of the combs as illustrated in Fig. 1, or a groove 12 adapted to engage a complementary rib I3 in the back of each end tooth 5, as illustrated in Fig. 3. The head cap Ill has extending axially from the center thereof a long shank M which may be integral with the cap [0, as illustrated in Fig. 1, or in the form of a long bolt l5 having a head I6 embedded in the head cap ID, as shown in Fig. 3. The shank Hi or I5 is provided with a screw threaded end portion ll adapted to engage complementary screw threads in an extension of the recess 8 in the handle or preferably a nut l8 fitting in said extension.

By reason of this construction all of the combs or other hair-treating elements may be assembled in radial arrangement with respect to the axis of the shank with the rabbetted portion or" the cap in Fig. 1 engaging the complementary recess in the end of the teeth 5 as shown in Fig. 1, or the rib onthe back of each tooth-5 occupying the groove 12 in the cap Ii] as shown in Fig.3. Each of the extensions of the back of the comb may then be drawn together and inserted in the socket 8 of the handle and upomrotationrof the handle in the proper direction the extension drawn into the socket 8 of the handle and :the effective length of the shamirsholttfined ,in such manner as to clamp the backs of the comb firmly together and the combs firmly upon the handle.

By reason of this construction the combs can .be initially rigidly and wreadily assembled and upon breakage or damage to any of the combs the same ;can be readily removed and replaced by unscrewing-the handle, substituting anew-comb andagain screwing up the handle.

The construction disclosed .in Figs. 5 and 6 comprisesacombs similar to lthose above described :but alternating with brushes l9 embedded at their inner-ends in backs as having converging faces and clamped to the handle in the mannerabcve described In such :modified form any suitable number of brushes andacombs may thus be in- .sertedsradially between-successive combs.

Theteeth 'ofithe c0mbs;may of coursebe-of any desired length in accordance with the character .or :quality of the :hair beingtreated, andoi any suitable material, thermoplastic material being preferably temployed. Brushes of any desirable degree of fineness-may beiused.

In pperation the operator will graspthe handle :of the implementiorce at leasttwo of the hairengaging elements into engagementwitha strand of hair and :move the instrument with ,a transla- .tory motion lengthwise of the hair toward the end thereof and simultaneously impart arotative :motionto the implement which willtcause two or more-of "the hair-treating elementslsuccessively .to engage the hair and simultaneouslyand progressively bend the hair with an arcuate move- ,ment [transversely of the translatory movement and so progressively to bend the hair as to enable theresilient elasticity of thehairs to restore nat- .uralwaves therein or to-induce such waves-therein and to produce curlsatthe ends of the strands ,of hair.

It will be apparent-that the particular embodiment.o f the invention shownand described herein is of an illustrative character and that various modifications in construction and arrangement of parts may be made within the spirit and scope V .of the ,followingclaims.
