1,927,544 HAIR WAVING APPARATUS Ralph L. Evans, New York, N. Y., assignor to Zotos Corporation, New York, N. 'Y., a corporation of New York Application June 24, 1932. Serial No. 619,024

4 Claims.

The object of my invention is to provide a novel apparatus for use in permanently waving croquignole wound hair by exothermic means, said apparatus including a shield forming a part of the tress clamp and which serves thedouble purpose of holding the pad containing the exothermic material in its operative position around the croquignolewound tress and also of protecting the scalp from the heat or vapor generated .10. by the said exothermic material.

A further object is to provide an apparatus of the above character in which the clamping members of the sheet clamp are developed to form the members of the shield as well as to form the 15. uprising ears in which the tress wound mandrel is mounted.

A practical embodiment of my inventionjs represented in the accompanying drawing, in which Fig. 1 represents a side view of my improved,

hair waving apparatus as in use;

Fig. 2 represents a cross section taken in the plane of the line II-II of Fig. 1;

Fig. 3 represents a top plan view of the apparatus as in use;

Fig. 4 represents anend view of the same;

Fig. 5 represents a side view of the combined clamp and shield in its closed position;

Fig. 6 represents an end view of the same;

Fig. '7 represents a top plan view of the combined clamp and shield;

Fig. 8 represents a cross section taken in the plane of the line VIII-VIII of Fig. 7, looking in the direction of the arrows; and

Fig. 9 represents a top plan view of thecom- 3 bined clamp and shield in its opened position.

The mandrel 1 on which the tress is to be wound in the croquignole mannermay be'of any well known or approved form, its squared end being denoted by 2 and its cylindrical end by 3.

The divided tress clamp comprises two sheet metal channel members 4 and 5 for receiving and holding the two tress engaging strips 6 and 7 of suitable yielding insulating material. .These clamp members 4 and 5 are developed to form the divided shield, the shield members comprising the bottom 8 and 9 and the uprising sides 10 andll.

The clamp members 4 and 5 are also developed to form the two members 12 and 13 of a divided uprising ear having a slot 14 for the reception of the cylindrical end 3 of the mandrel.

One of the clamp members, the clamp member 5, for example, is developed at the other end of the I clamp to form an uprising ear 15 having a recess 16 for rotatably mounting the squared end 2 of the mandrel 1.

A link 1'7 forms a hinged connection at one end of the clamp between the two clamp members and atthe other end of the clamp a link 18 is so pivoted to one of the members, the member 4, for example, and is provided with' a cam lever 19 for engaging the other member to hold the members in their closed position.

The pad which I have shown in connection with my improved apparatus comprises a suitable backing sheet 20, an envelope 21 containing the exothermic material 22, and an absorbent sheet In practice, either the tress may be moistened before or after it is wound on the mandrel or the absorbent sheet 23 may be moistened, or both the tress and the sheet may be moistened before the pad is applied to the tress. If the envelope 22 which encloses the exothermic material is nonporous, it will be necessary to puncture the same before the pad is used. The pad is caused to embrace the croquignole wound tress by inserting the sides of the pad into the shield, the sides 10 and 11 of the shield serving to not only hold the pad in its operative position but also to protect the scalp from the heat or vapor generated by the exothermic action of the chemical used in the pad.

A pad 24 of felt or other suitable material is inserted between the tress clamp and the scalp.

It is evident that various changes may be resorted to in the construction, form and arrangement of the several parts without departing from the spirit and scope of my invention, and hence I do not wish to be limited to the particular embodiment herein shown and described.

What I claim is:

1. In an apparatus for imparting a permanent wave to hair, a divided tress clamp comprising two sheet metal members extended to form a divided shield having two uprising sides serving the double purpose of holding an exothermic material containing flexible pad in position and also of protecting the scalp from the heat or vapor generated by the said exothermic material.

2. In, an apparatus for imparting a permanent wave to hair, a divided tress clamp comprising two sheet metal members extended to form a divided shield having two uprising sides serving the double purpose of holding an exothermic material containing flexible pad in position and also of protecting the scalp from the heat or vapor generated by the said exothermic material, said wave to 'hair, two tress engaging strips and a divided tress clamp comprising two, sheet metal channel members for receiving and holding said strips, said members being extended to form a divided shield having two uprising sides serving the double purpose of holding an exothermic material containing flexible pad in position and also of protecting the scalp from the heat or vapor generated by the said exothermic material, said clamp members being further extended to form ears for mounting a tress winding mandrel.
