hair a permanent spiral wave.

Heaters heretofore used in the-waving of hair by the spiral process, as compared-to those used where a so-called Croquignole wave is desired, have commonly been hollow cylinders of such a fixed size that the wound body of hair generally has not filled the hollow'space in the cylinder. This is due to the fact that these heaters have necessarily been made sufiiciently large 'to accommodate readily various amounts of hair. The member on which the hair is wound as a consequence, usually extends at an angle to the axis of the cylinder, so that some surfaces of the coil of hair come closer to'thesource of heat than others and air spaces intervene between other portions of the hair and the heater. This has resulted in uneven heating of thehair.

An object of the present invention is to provide a heater for the purpose indicated, which shall have its heating elements constructed so as to be held in firm contact withthe hair along the entire length of the heating surfaces, to provide for even heating of the whole coil of hair, and which, at the same time, shall be capable of being readily manipulated and applied to the hair. A further object is to provide sucha heater formed of a plurality of heating elements adapted when'in use to form a substantially closed chamber within which the coil of 'hair is retained while it is being heated, in the presence of steam, or other treating vapor or solution. A more specific object is to, provide such a heater in which the heating surfaces are efiiciently utilized, and in which the operating mechanism is located at one end of the heating surfaces,that is to say, at the opposite end of the heater from that adjacent the head, and in which the operating mechanism is combined with a heat insulating handle so that itmay be held and operated-by one hand. I

A feature of the invention is the provision of a heater of this character which is simple and inexpensive to construct, wire and. assemble. Other objects and advantages of the invention will become apparent as the description of one formof heater constructed in accordance with the invention proceeds.

Referring now to the accompanying drawing forming apart hereof:

Fig. 1 is a side elevation, partly in section, of

one form-"of heater constructed in accordance with the invention.

Fig. 21s a similar view but showing the heating elements in open position ready toreceiveacoil T Fig.8 is a plan view, also partly in'se'ctiomo the heater shown in"Figs.1 and 2, and

Fig. 4 is a section taken on the line 4-4 of Fig. 'l'looking in the'direction ofthe arrows.

'In the'drawing; the heater is shown-as compris- 'ing'a'pair of opposed elements-5 and 6, each of which may include a metal 'casing'of-any suitable "construction: enclosingan electrical resistance or heating element lyone'of which'is shown =di-a- {grammaticallyinFig.-4. The two sections band -6 "preferably have their inner opposed faces concave so-asto form a substantially cylindrical or elliptical chamber'whose surfaces are adapted to engage acoilof hair. Each'section mayconveniently be'formed' of a pair of curved,-stamped .metal' parts'secured together in any suitable-way, as by over-turned tabs, rivets or by WeldingJto produce a completely" closed unit for housing-the "heating element 1. The upper -member 5' may be provided with asuitable extension 8 secured, 'in-any convenient manner,-toan oval: or circular disc or baseplatellwhich is in turn secured to or mounted on the inner wall of an "annular or oval-shapedyhollow handle I0 com-posed'o-f heat insulating material such as wood, hardrubber, bakelite, or the like, and having an opening I [la generally aligned with the" space betweenthe heaterelements. Theplate 9 is preferably-also -formed=of heat insulating-material and has an opening aligned with the opening Illa. The hanbeing preferably connected in series, one lead being accordinglyconnected to the heating element in member 6, which is connected by wire I3 to the heating element in member 5, .while the latter, in -turn,.is connected tothe other lead.

Provision is made for spreading the heating elements 5 andiB topermit the ready insertion between them ofa coil of hair and also to accommodate theh'eater to coils of different sizes. The arrangement .provided for moving the sections toward one another during the heating, is adaptments while being simple ed to maintain their opposed faces in parallel relation. For this purpose, pairs of spaced links l4, [5 may be pivoted to the sections 5 and 6, and the ends of a yoke member l6 may be pivoted to arms I5 between their ends, the center of the yoke being pivotally connected to an operating lever II fulcrumed as at H! upon the heating element 5 which, as explained before, is rigidly carried with the handle 9. In order constantly to urge the sections 5 and 6 toward one another, a suitable spring l9 may be provided, this being suitably coiled about the pivot l8 and having arms 20 and 2| urging the lever l1 outwardly from the member 5. The hollow handle 9 is so arranged and is of such size interiorly asrto permit the proper relative motion of the section 6 with respect to the section 5, as shown in Fig. 2, and may extend over the ends of the heating elements sufficiently to permit the operator to get a good grip on the handle without danger of burning his hand through contact with the heating elements. The end of the lever I! may be formed of heat insulating material 22 having a roughened thumb engaging surface 23, and the plate 9 may be cut away to permit the lever H to be depressed until the portion 22 or the yoke l6 abuts against the top of element 5, to limit the movement of the parts.

In order to aid in preventing the escape, at the sides of the device, of steam which may be generated in the course of the heating, suitable flanges 25 may be secured in any convenient manner to one of the heating elements and may be adapted to overlap the other heating element when the two are in operative positions. These flanges may conveniently be formed as an integral part of the top plate of the heating element 5. The laterally extending portions of the flanges 25 may be suitably cut away as shown at 26 to permit the links 'l4, IE to extend therethrough. When the device is in use, it is desirable to employ some type of clip, of any suitable known construction, to tightly clamp the end of the usual pad around the tuft of hair which is coiled within the pad. This clip is applied at the end of the heater opposite the handle 9, and adjacent the head, to prevent steam from escaping from this end of. the device, and burning the scalp. When the device is substantially filled by the coil of hair, any steam generated thus tends to remain in the device unless it finds its way out through opening [0.

When it is desired to open the jaws or, in other words, spread the heating elements, it is simply necessary to grip the handle 9 in one hand and place the thumb upon the surface 23, to depress the lever l7 and swing the heating element 6 from its position in Fig. l to its position in Fig. 2. "Ihereupon, the coil of hairto be heated may be inserted endwise in between the'heating elements, and the thumb removed from the lever I1, thus permitting the heating elements to be pressed against the hair between them with a uniform pressure along their entire length.

There is thus provided a simple compact heaterwhich admirably satisfies the various requireand inexpensive to manufacture.

Ihe terms and :expressions which have been employed are used as terms of description and not of limitation, and there is no intention, in a the use of such terms and expressions, of excluding any equivalents of the features shown and described, or portions thereof, but it is recognized that various modifications are possible within the scope of the invention claimed.
