UNITED STATES ROBERT F. SIMMGNS, OF CLEVELAND, OHIO.

ELEGTEIG I'TAIR VIAVER.

Application filed July 31, 1924.

To aZZ whom it may concern.

Be it known that 1, ROBERT P. SIMMONS, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful improvement in Electric Hair Wavers, of wh'ch the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates generally to an electrically heated air waving implement and more particularly to certain improvements on the electric hair waver disclosed in my patent of April 1, 1924: No. 1,488,621.

The object of the present inventlon 18 to materially simplify the construction of the apparatus and correspondingly reduce the cost of manufacture 011 quantity production basis.

Another object of the invention is to so construct the apparatus that the proper degree of heat is obtained with the employment of a minimum amount of resistance element for producing the heat.

Other and further objects will appear as the description proceeds.

The invention consists broadly in providing a sinuous shaped metallic casing with spaced heating elements arranged therein. The invention also consists in certain details of construction and in the manner of combining or arranging the same all of which will be fully described hereinafter and set forth in the appended claims.

In the drawings forming a part of this specification, Fig. 1 is a perspective view of a hair waver constructed in accordance with my invention, a portion of the outside plate being broken away in order to disclose the heating element between the wave forming heated plates; Fig. 2 is a transverse sectional view of the metallic casing with the heating elements arranged therein; Fig. 3 is a similar sectional View showing a slightly modified form of easing; Fig. 4: is a detail perspective View showing one of the sinuous plates with the spacer arranged thereon and the heating wire coiled upon said spacer; Fig. 5 is a detail perspective View of the spacer removed; and Fig. 6 is a plan view illustrating the manner of winding the resistance element.

In carrying out my invention 1 provide a sheet metal casing or envelope which is preferably made from two substantially similar wave-shaped metallic sheets 6 and 7 re- Serial No. 729,218.

spectively which are placed together and united in any suitable manner along their edges, said plates or at least one of them being sufficiently upset or deformed to provide sufficient space between the plates to receive the heating elements and the spacer plate for positioning the same properly within the metallic casing or envelope. The middle or crest portion of the wave-shaped plate 7 has a tubular stem 10 connected thereto which stem is provided with a handle 11 to facilitate the manipulation of the hair waver. It will be understood, however, that the tubular stem can be connected to the plate 6 if so preferred. The stem and handle are hollow to permit the connection to the heating element 5 to be extended through the device to the flexible exterior connection 12.

At a point 14 on the supporting stem 10 is a pivot 11 having prongs 16 and 17 which pull the hair down into the crevices or the extremity of the looped portions of the waver, pressing the hair against the crest or middle portion of the plates and against the portions 18 and 19 of the plates 6.

The lever is manipulated by means of a handle 20 which is closed with reference to the handle 11 as indicated in dotted lines at 21 where the hair is forced down against the heated casing by means of the prongs 16 and 17.

As thus far described, the features of construction are substantially the same as those disclosed in my patent previously referred to. In that patent, however, the heating element comprised the core having a heat ing wire thereon which core and heating wire was covered with suitable insulation material and then the core, heating wire and insulating material were given a sinuous shape before insertion between the sinuous shaped metallic plates.

In my present invention, however, I propose to arrange the heating elements in the outer side portions only of the casing. In order to provide for the proper and expeditious arrangement of the heating wire in this spaced relation, I employ a spacer 28 which is arranged centrally of the plate 6 and has its oppositely curved edges extending over the spaced bends in the plate and these 0ppositely curved edges are provided with a plurality of tongues or books 28 upon which the loops or coils 27 of the insulating heated wire are arranged. This heating wire 27 is of the proper resistance quality to produce the proper heating effect and is covered with suitable insulation. The insulated heating wir is thoroughly flexible and is looped or coiled back and forth as shown from one end of one side of the plate 6 to the opposite end thereof and it is then carried over to the opposite side and coiled or looped or folded upon the opposite side member of this plate and it will of course be understood that the spacer 28 occupying the central portion has the oppositely disposed hooks or tongues 28 upon both sidesor edges for the reception of the strands or loops thereon.

Where theinsulated wire 27 passes, from one side of the plate to the other, thereis a dead portion 27' which will carry the current but will not heat to any appreciable extent, this dead member 27 being copper or other suitable conducting material. The heating wire 27 can be connected, as pre viously described, at the points 5 to the wires leading through the tubular handle 10 or if desired, portions of the insulating wire itself can be carried partially through the tubular handle but there is no necessity for extending the heating wire beyond the points 5. By arranging the heating elements at the sides of the wave-like plate I have obtained an even distribution of the heat, inasmuch as the sides becoming heated convey or conduct the heat inwardly, and by properly proportioning the amount of wire in the spaced. heating elements, I am able to obtain a uniform heating of the wave-like plates.

It will of course be understood that instead of winding or coiling the wire 27 back and forth in vertical order as shown, it could, if so desired, be carried back and forth in horizontal order by the proper arrangement of the spacer, but in practice I have found the vertical arrangement particularly satisfactory and I am able to put into the, minimum space the. maximum amount of properlyinsulated heating wire.

After the insulated wire has been properly arranged uponfthe plate 6, the plate 7 is placed thereover and envelops the same. The edges of the plates 6 and 7 are united as previously described, and it will be understood that any other mod of connection could be employed and furthermore the plates 6 and 7 could be so stamped that they could be held together by frictional contact. Instead of making the plate 7 similar to plate 6 in wave formation, it could extend straight across the central portion, as most clearly shown in Fig. 3.

All of the other parts of the device, however, are constructed and arranged in exactiv the same manner as previously described. The arrangement of my electric hair waver is such that the waver may be moved over the difierent parts of the hair and a wavy sinuous shaped metallic casing, and flexible.

heating elements contained in the outer members of said casing, and means forbringing the hair into contact with said casing.
