To all whom t may concern.'

Be it known that I, ZivA POPIN, residing at New York, in the county and State of New York, have invented certain new and useful Improvements in a Heater for Waving Hair, of which the following is a specifi-y cation. y

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

One of the objects of the invention is to y be utilized in imparting what is known as a permanent set or curl, in what is known as a Marcel wave, that is to say, a wave in which the curl is imparted to a lock or tuft ofhair in a direction at right angles to its length, in contradistinction to a spirally formed curl or wave, such as is imparted in the now utilized processes of permanent hair waving.

A further object ofthe invention is to provide a heater which conforms to the shape of the head, whereby the inner' end of the wave to be imparted to the lock of hair will terminate at equal distances from the scalpf v A further object of the invention is to provide a heater` ofthe above character, which may be more easily positioned upon the hair wound upon a curler than has been possible to do with heaters as hitherto constructed.

Other objects and aims of the invention, more or less specific than those referred to above, will be in part obvious and in part pointed out in the course of the following description of the elements, combinations, arrangements of parts and applications of principles, constituting the invention; and the scope of protection contemplated will be indicated in the appended claims.

In the accompanying drawing, wherein `I have illustrated a preferred form of embodiment of my invention:

Figure 1 is a plan view of theinterior of the heater in open position, electrical wiring being shown in dotted lines.

Figure 2 is an elevational upper side of the heater.

view of the Figure 3 is a sectional View taken substantially on the line 3-3 of Figure 2, looking in the direction of the arrow; and

Figure 4 is a sectional view showing the manner in which the heater is employed lin carrying out my improved process. A

Referring now tothe drawing, wherein similar reference characters refer to similar parts throughout the several views thereof, the reference numeral 1 denotes one part of the heater, and 2 the other part thereof, each lof said parts being of semi-cylindrical form, as shown, and hinged together, as at 8. Each part comprises an shell" 4, which is preferably formed of a light material, such for instance as aluminum, and located in each core 5, each core having positioned thereon a coil of resistance wire, as indicated at 6. Pairs of leading-in wires 7 and -8 are connected with the resistance wire on each core, so that when the circuit is closed through the leading-in wires, the resistance wires will heat the cores, whereby the surrounding parts will be vheated thereby. Strips of insulating material 9 and 10 are outer hollow shell is a metallic shown interposed between the lateral sidesof the core and the ends of the chambers within the shell '4, thereby preventing the' core from being displaced from its normal position within the shell.

The shell 2 at its free edge is preferably provided with a slot 11, which is adapted to receive a ton e 12 formed upon the free edge of the shell 1, as indicated in Figure 3 of the drawings. The parts are locked in the position shown, as by means of a resilient wire clip 13, which is pivoted at 14 to the shell 4, and which is adapted to be positioned about the hinged parts, as indicated in Figures 2 and 3. One of these wire clips is provided at each end of the device, as indicated in Figure 2.

It will be seein, therefore, that these clips serve to resiliently hold the hinged parts in close relation about the hair to be treated. It will also be noted that the parts 1 and 2 are arc-shaped in form, each having the concaved part 15 and the convexed part 16, so

' the free ends extended between the actual use the scription or ligure it will be on and that when the hinged parts are in close position they have the form of a'bent tube; the concaved part being intended to conform to the shape of the hair of which the wave or curl is to be imparted.

The use of my improved device is illus trated in Figure 4 ofthe drawings, in which cated at 17 is wound upon a curler 18, such as illustrated in my co-pending application Serial Number 297,765. v

Upon the curled hair is positioned a Y' moistened impregnated carrier 19, such as illustrated. in my co-pending application, Serial Number 297,767, said impregnated carrier being wrapped about the hair', and free ends of the respective parts of the heater with the strand of hair between the ends of the carrier, as clearly shown in the drawings.

ver the curled hair, and the impregnated carrier, -is ositioned al split tube 20, which is prefera'bll7 composed of a pasteboard tube.

'With the. parts in the position shown, the wire clips 13 are swung into the position shown in Figures 2 and 3 of the drawing, thereby resiliently locking the parts lto,- gether. The tongue and groove construction of the free ends of the cylindrical shell parts serve as a baiile to prevent the heat from esca ing toward' the scalp, the latter being furt er protected against theheat by lmeans of the protective device or shield lindicated at 21, which is of the construction shown in v my co-pending application Serial Number 297,766. f I

-It will ybe understood, of course, that in interior parts of the'device will be more closely associated with the hair, impregnated carrier and the tube in the interior wall of the heater will be in close engagement; the slight separation of these parts shown in Figure 4 being in the interests of clearness of illustratio It will accordingly be seen that Ihave provided a device well adapted to attain, among others, all the aims and objects above pointed out, in an extremely simple manner. The divided construction of the heater enables it to be readily positioned upremoved from the hair to be treated. It will also be noted that the cable 22, which is composed of the leading-in wires 7 and S, is dlsposedl mldway of the length of the heater, whereby when the same is suspended it will be nlcely balanced, thereby relieving any strain upon'the hair.

s many changes could 4be made in this construction without departing from the scope of the following claims, it is intended that alllmatter contained in the above deshown in the accompanying ters Patent is:

noted that the hair indib drawing shall be interpreted as illustrative only and not in a'limiting sense.

- aving thus described my invention what I Vclaim as new and desire tov secure by Letl1. A heater comprising a pair of semicylindrical parts hinged together, each part eing provided with a heating element, the

free meeting edges of said parts being so con-l stru-cted asto permit a layer of hair to pass therebetween.
