This invention relates to improvements in machineless permanent wave devices and has for its object the provision of a machineless permanent wave device which will permit the permanent waving of the-hair at home with a minimumof apparatus and expense.

A particular object of the invention is the provision of a hair waving device for providing a permanent wave, in which the waving is expedited by a novel method of enclosing two or more curls within each permanent wave unit.

A further object of this invention is the provision of a permanent wave unit for home use, which will be safe to use, which will be easy and quick to operate, and in which insulating means are provided by which the chemically generated heat will be effectually confined for the purpose of forming the permanent wave, and in which there will be no tendency for the unit to be accidentally opened or displaced with consequent loss of heat and inefficiency of operation.

It should be noted that this improvement in permanent wave devices belongs to that type of device in which the heat is chemically and not electrically generated.

Further objects will be apparent from the specification and drawings which illustrate preferred embodiments thereof, it being understood that the above statement of the objects of my invention is intended generally to explain the same without limiting it in any manner.

Fig. 1 is a perspective view showing a number of my permanent wave units applied to the hair of the user of this device.

Fig. 2 is an enlarged perspective view showing one of the units in place and functioning.

Fig. 3 is a perspective view of one of the hair waving units in open and inoperative position, showing the manner in which two curls of hair are confined upon the surface of a single hair waving unit.

Fig. 4 is a rear view of the device shown in Fig. 3, showing the manner in which the ends of the curls shown in Fig. 2 are held Within the unit.

Fig. 5 is a perspective view of the unit showing the manner in which the curls are confined within the unit, but before the outer covering is applied.

Fig. 6 is a sectional view on the line 6--B of Fig. 2.

Fig. '7 shows a front View of a different embodiment of the unit, exclusive of the immediate envelope or container for the curls and the heating pad.

Fig. 8 is a sectional view on the line 8-8 of Fig. 7.

Fig. 9 is a front view of another embodiment of wrapper, excluding the envelope for the curls and heating pad, in which the wrapper is narrower than in the form shown in Figs. 1 to 6 inclusive. and in which the insulatingpad is of a different shape than the insulating pad shown in Figs. 1 to 6 inclusive. v

Fig. 10 is a front view of still another embodiment of wrapper and insulating pad, a sectional view of which is shown in Fig. 11 on line I II l of Fig. 10.

Fig. 12 is still another embodiment of a front view of the wrapper and insulating pad slightly difierent from the wrapper and insulating pad shown in Fig. 10.

The invention comprises the following necessary elements which are best illustrated with reference to Figs. 3 and 4:-

These figures show an insulating pad made of corrugated paper or thelike, which has the slots 2|. Different forms of these slots which serve as guides for the ends of the curls are shown in Figs. '7 to 12 inclusive. Permanently attached to the insulating member 20 is the paper wrapper 22, having positioned thereon the pliable and waterproof covering 23, to which is stapled or otherwise secured the heating pad 24 having a cover of tin foil or'the like 25. The envelope 24 contains the usual powder which when wetted evolves heat, and as this type of heating pad is already well known in the art and forms no part of my invention, I do not specify any particular composition for use herein.

It should be noted that the slots 2! are so shaped with a wide angular opening 26, a narrow central portion and an enlarged end portion 21, so as to effectively retain the ends of the curls therein. It should also be noted that the slots 2| are cut in parallel and in staggered relation to each other, as shown in Fig. 4, so as to provide the maximum space for the curls within the cover of the device.

In the embodiment shown in Figs. 3 and 4, I provide room for two curls within a single wrapper, but it is evident that more than two curls can be provided within a single wrapper by the provision of additional slots. The individual curls C are gathered on flexible hair pins 28 of the usual type as shown in Figs. 3, 5 and 6, the beginning of .the curl being shown in Fig. 4, as the ends 29 do not denote the ends of the curls but the beginning of the curls as they lie adjacent to the scalp, the scalp being protected from contact with the rest of the curls and from contact with the heat engendered in the envelope 24 by the protective pad 20. In this embodiment I have shown a protective pad 20 made of corrugated paper board which, on account of its cellular structure, provides protection to the scalp, is easily slotted and can be made in a variety of forms. After the curls C are wound upon the pins 28, water is applied to the envelope 24, which is then laid or wrapped around the curls as shown in Fig. 5. The ends of the wrapper 22 having the protective layer 23, are then wound tightly around the envelope and adjacent tin foil sheets .25 and the whole is effectively secured in place by the terminal edging 30 which consists of a continuation of the body of the wrapper 22, within which is confined a flexible thin metallic elementi3l.

In Figs. 3, 4 and 5 the metallic edging 30 is shown in the open position, the ends or extensions of this edging 30 are indicated as 32 in Fig. 3. In Fig. 2, these extensions 32 are shown bent inwardly within the body of the wrapper so as to securely confine the contents of the wrapper against displacement.

Figs. "7, 9, 1,0 and 12 show different embodiments of the wrapper 22 with different forms of the insulating pad 20 and these figures also show various forms of slots in the insulating pad which may be varied for convenience. In Fig. 4 the slots are shown cut horizontally in the body of the insulating pad, whereas in Figs. and 12 the slots are shown .cut vertically in the body of the insulating pad.

For instance, inFig. '7, 33 indicates staples to attach .the pads to the outer wrapper, in both of theseforms the pads being of such shape that they do not need to be provided with slots. In the embodiments shown in Figs. '7 to .12 inclusive, the envelopes containing the heat producing medium need not be attached to the body of the wrapper, but can be introduced separately. In'Figs. l0 and '12 it will be noted that the curls maybe easily introduced through the vertical slots shown, although my preferred embodiment is the .form of pad and slots shown in Figs. 1 to 6 inclusive.

In 'Figs. -l to Ginclusive the staples 34 are used to attach all of the parts of the device together, so as to form .a single .unit. It is apparent that the shape of the wrapper may be varied, .the shape of the pad may be varied, and other ,changesmay be made in the device without departing from the spirit of myinvention, the principal points of which are the novel means shown for introducing a plurality of curls for permanent waving .of this type within a single wrap- .per and also the .means shown for effectively enclosing the curls and accompanying envelope and wrapper in a single workable unit.

In addition to the insulating pad of corrugated paper shown in the drawings, an additional pad of like size may be used, but where such an additional pad is used, the slots in same should not register with the slots shown in the pad 26 but-should be at an angle to such slots so that the ends of the hair will be more eflectually held by the two non-registering bodies so that the slots in the additional pad will be at a difierent angular relation to the upper pad, and there will be no coincidence of slots.
