HAIR-WAVING DEVICE Application filed July 18, 1930.Y Serial No. 468,814.

`My invention relates to hairwaving devices which are adapted for use with electricity, and it is addressed particularly to the simplification of the means required for imparting to the hair the wavy'appearance which is known as a permanent wave.

The main Vobject of the invention is to enable a person to give to her hair a permanent wave without the*V aid of anyone, and to impress the said wave upon the hair in a single operation. Y

Another object of the invention is to make it possible for one to put a waveinto her newly grown hair without affecting the re-A .15 mainder of the wave-impressed hair, so that, as a fresh growth reaches the requisite length,

a new wave near to the scalp is added, thus keeping hair permanently waved without subjecting that already waved to another waving process.

Another obj ect of the invention is the provision of means which are so combined that they will enable an entire head of hair to be waved in about an hour. Y

Another obj ect of the invention is the production of a hair waver which, while of great etliciency, is simple in operation, durable in constructiomand provides a practicaLgsa-fe and inexpensive device for home use.

Other objects, and advantages will be evident from the following description, taken `in connection with the drawings forming part hereof, corresponding parts in said drawings being designated by similar nu- Amerals of reference, in which f `Fig. ,l is a perspective view of my improved device;

*Fig 8 is a view from the left of Fig. Il showing the elongated opening indicated in section in the former figure.

The art of permanent hair waving as generally practised at the present time consists broadly of three steps, (l) softening the hair with a suitable liquid, (2) steaming it with the steam emanating from said liquid, and (3) stretching the cells of the hair while it is being steamed so that the cells will be elongated and cause the hair to retain the curls given to it while thus stretched under the steam. Heretofore permanent wave devices have accomplished this result by winding the hair around small rods and then tightening it as the steam is applied. As a consequence the hair naturally comes out in the form of round curls'which, by various means, must then be` set and pressed to cause them to assume the wavedefect desired.

By the present invention, however, the operation is greatly simplified. The hair is placed in the waver fiat, and by the method and means hereinafter described, comes out in the form of an undulating wave instead of a curl, and retains the wave imparted to vit even after repeated washings.

This result is accomplished by my novel device which is shownin perspective in Fig. l of the drawings. It is made up of a hollow handle 1. Attached to it and partly extending into the same is a hollow metallic curved tube v2 for the reception of a heating unit. The tube 2'having a curvature'to conform with the head is equipped with an oval bushing member of metal 8. Encircling the tube 2 is a substantially oblong housing 5 which is open at thefront and is provided with an elongated opening 6 at the back, the length of Y said opening being larger than the vcircumference of the tube 2, The member 5vis held in position on tube 2 by means of its downwardly projecting. wall 7 surrounding the opening 6 being caught and held between the bushing 3 and the adj acentend of the handle. It is obvious thatthis construction permits the handle -l and tube 2 with its attached parts lOO to be moved as a unil` within the limits prescribed by opening 6.

Jaw S neai end is equipped with a knohbed l2 to engage with socket ll. a wavy its length the said das ,inobbed pressure screw itor the purpl hereinafter described. F r Vthe purpose of protecting' the scalp from the heat of the Waver a itrip of non-heat-condu ting niaterial 15 is attached to e lower surface ot the jaw f). Both jaws 8 and 9 pro-videl with small grooves 16 along the length of their edges to accommodate pieces or strips et rubber or other suitable material lijf',

A. removable. jacket or bag;` of viven asbestos cloth or any o-the" .suitable ina rial apted to he placed or tube is indicated by 153, and 1S) designates a perlorate l metal protector in the forni oi' the cylinder clcsfd one end adapted to be slipped over the said j aeket.

la the ensuing; description et ni" ii in practise. the work of 'the indivi.' ments and their tio-operation in the production ot the finished result will be made clear.

Assuming' that a heating unit has been placed in tube 2 and connected in the usual way, as by cord 20, to a source of electricity, and that the user desires to give herseliL a. permanent wave, the hair is parted and draped on each side of the head. rihe waver is held firmly in the hand by means o1" handle 1, the tube bearing its removable cloth jacket 1S (which has been previous moistened with a suitable pern'ianent wave liquid), and over that the perforated metallic cylinder 19, being raised somewhat and held against the inside of the top oiJ jaw 8. A section of the hair is then laid smoothly fiat over the lower jaw 9, the scalp-protecting member 15 Contactini` with the head, a tter which the upper jaw is closed and screwed into place by means of locking;` sere 12 and socket 13, The members are now in the position illustrated in Fig. 5, the jaws positively formino' a closed tube, an d the enclosed portion of the hair being stretched and held straight across and between the upper and lower jaws, where it i held practically immovable between the strips oi rubber fastened to the edges of aws S and 9. The screw 11i is next operated to press the tube with its wet jacket and perforated protector down upon the hair, as shown in Fig. (i, but not until steam has been produced by heat on the wet jacket, The hair cells are thus stretched or elongated as the hair pressed into the torni ot a wave, which elongation is necessary to make a wave permanent. As stated, however, the hair is not stretched until it is being subjected to the steam generated by the liquid applied to the wet jacket. rlhe operation is then repeated with another section ot the hair until the desired wave. has been imparted to the entire head of hair.

While in the embodiment of' my invention herein shown and described I employ a locking screw to hold the jaws in close engagement with each other, itis obvious that other means may be utilized for the purpose accomplished by saidscrew, which is to so securely clamp the said jaws together that the hair placed therebetween is held practically immovable between them or the strips of rubber fastened to their edges. It is clear, too, that any suitable material may be employed in place of the rubber strips 'for assisting or rein't'orcinof` the jaws in maintaining a lixed grip on sa-idliiair.

@ne ot tl e advantages of my waver is that because ot its curved construction it conforms with either the side or back of the head. thus enabling` a short or a long wave to be placed wherever desired and at any angle.

Another advantage is the ease with which the chemical needed in permanent waving is put to use through the saturation of an absorbent jacket or bag,- quickly attached to and removed from the heating element 2.

lllhile I have described the preferred torni of my invention7 I do not wish to be limited strictly thereto as Various changes may be made therein without departing from the spirit of the invention or the scope of the appended claims.
