PEBMANENT-HAIR-WAVING APPARATUS.

Application filed July 80,

This invention relates to a new and improved heater used in the art of permanent hair waving.

An object of this invention is to provide a permanent hair waving apparatus in which a single heating element produces substan tially the same results which have lpreviously been obtained by permanent air waving apparatus which are provided with two or more heating elements.

Another object of this invention is to con struct a heating device provided with pockets for retaining the vapors used in treating the hair during the waving process.

A further object of this invention is to construct a permanent hair waving apparatus, the various parts of which can be stamped from sheet metal.

The invention possesses other advantageous features, some of which with the foregoing, will be set forth at length in the following description, where I shall outline in full that form of the invention which I have selected for illustration in the drawings accompanying and forming part of the present specification. In said drawings I have shown one form of permanent hair waving apparatus embodying the improvements of my invention, but it is to be understood that I do not limit myself to such form, since the invention, as set forth in the claims, may be embodied in a plurality of forms.

In the drawings:

Figure 1 is a perspective view of my apparatus in its operative position.

Figure 2 is an end elevation with the arm of one of the clamping members shown partly in section.

Figure 3 is a sectional view taken on the line 3-3 of Figure 2 looking in the direction as indicated by the arrows.

Figure 4 is a perspective view of one of the clamping members.

Figure 5 is a perspective view of the other clampirg member to which a heating element and terminal block have been attached.

Figure 6 is a cross sectional view of th heating element per se.

The improvements of my invention relate to permanent hair waving a paratus such as are now in common use. 11 the construc tion of such apparatus it is customary to employ two spring pressed pivoted semi-cylindrical clamping members. Each of the clamping members is provided with a heat- 1927. Serial 1T0. 209,495.

ing element, both of which are of a semicyllndrical form and each of which is nested wltlllll one of the clamping members. In the use of these devices the hair to be waved is wrapped about a mandrel after first being washed in certain chemical solutions. A layer of flannel or other suitable material 1s then wrapped about the hair, a la er of metal gauze is wrapped about the annel and over this is placed a clamping member such as above described. I propose to construct a device in which a single heating element is so positioned with respect to both of the clamping members, that heat will be readily conducted from it to both of the clamping members and so serve the same purpose and produce the same results which have previously been accomplished by the use of two heating elements. I further ropose to get a more even distribution of oat by providing the shell or jacket, in which the heating element per se is carried, with apertures. These apertures also serve as pockets in which the vapors produced by the chemicals in which the hair has been washed may be retained. Although the vapors'so used form no part of the present invention, it may be well to state that such vapors play an importantpart in permanently waving the hair, and that therefore the provision of these pockets for holding such vapors is an important improvement of my invention. The form of both the clamping members and the shell or jackets which enclose the heating element per se is such that they can be readily stamped from a piece of sheet metal. The heating element together with the shell or jacket is so constructed as to be readily detachable whenever desired.

In the embodiment of my improvements shown herein two T-shaped members enerally designated as A and B, and est shown in Figures 4 and 5, are stamped from a sheet of aluminum or other suitable metal. As shown in Figures 1, 2, 4 and 5 these T- shaped members have been shown as inverted. Midway between the arms 1 and 2 of the T-shaped members A and B are

lugs

4, 5, 6 and 7. These lugs as shown in the various figures are struck up at right angles to the arm members 1 and 2 and are provided with apertures 31 through which a pin 3 is placed to pivotally secure the members A and B. A spring 10 is coiled about the pin 3 and has one of its ends pressing against the arm 1 while the other end is pressed against the arm 2 and so serves to urge the cross bars or clamping

members

8 and 9 to a closed position. The clamping members. 8 and 9 have been bent into a sermcylindrical form as shown in Figures 1, 2, 4 and 5, and are provided at their outer edges with

fiber strips

41 and 42, which prevent the hot edges of the clamping membars from coming into direct contact with the flannel covering. These strips are secured to the clamping members 8"and 9 by means of rivets 43. I

heating element of semi-cylindrical form generally designated as 12 is made up of a mica core about which a resistance wire 36 is wound and which is entirely insulated by mica strips 37. Metallic semicylindrical members 38, cover both the extellOI and interior surfaces of this construction and'all this is then socketed or enclosed in a shell 11. This shell 11 is made from a rectangularly stamped sheet of metal which has been bent into a semi-c lindrical form and whose outer edges 32 ave been bent back upon themselves as shown in Figure 6, to lock the heating element in place. The ends of the shell 11 have been struck up to close the ends of the heating element as a best shown at 33 in Figure 5, and the edges of the shell member are rounded ofl so as to prevent any sharp kinks from being formed in the permanent wave. The inner surface of the shell 11 is apertured as at 13 to ermit of a more even distribution of eat within the cylindrical member formed by the

clam ing members

8 and 9 and by the shell 11. ese apertures also serve as vapor pockets.

The shell 11 together with the heating element 12 is concentrically disposed within and secured to the clamping member 9 by means of a screw 14 which is engaged b a nut 15 in engagement with the outer sur ace of the clamping member 9. 1 As best shown in Figures 2 and 5, the up er left half of the shell 11 extends beyond the clamping member 9. This permits the upper half of the clamping member 8 to over-la this exposed outer surface of the shelf 11. By such a construction it will be seen that a substantial part of the cylindrical surface of the shell 11 is engaged by both the

clamping members

8 and 9. Since all the elements so far described are metallic with the exception of the insulation which customarily surrounds the heating element 12, it will be readily seen that heat is readil conducted from the shell 11, not only tot e clamping member 9, but also directly to the clamping member 8. V

A terminal block 16 is secured to the outer lower end of the arm 2 by means of a screw 17 which engages the nut 18 on the inner surface of the member 2. The leads to the heating element 12 are secured within this terminal block to the customary contact or socket members. A cord carrying a plug 19 is in turn secured to these contact members. The ends 39 of the resistance wire which 0 to make up the heating element 12 are t readed through apertures 34 in the with respect to the

clamping members

8 and 9 as above described, it will be seen that due to the fact that the heating element is in contact with both of the clamping members, conduction between these elements is obtained. By such a construction one of the usual heating elements can be done away with and the cost .of manufacturing these devices is thereby considerably decreased.

,The apertures 1n the shell surrounding the heating element serve to enclose the vapors which are beneficial to the waving recess and also permit of a more even distribution of heat.

The fiber strips prevent the flannel covering over the hair from being excessively heated. It will be noted that the metallic gauze which is placed about the flannel covering serves a similar purpose within the clamping members.

The entire construction may be stam ed Y from sheet metal, thus making an eflicient economical device.
