My invention relates broadly to hair wavmg apparatus and more particularly to a construction of casing for the'heater employed in hair waving operations.

One of the obgects of my invention is to provide a constructionnof heater for use in air waving apparatus having a casing capable of remaining at a relatively low temperature independently of the relatively high temperature to which the heating element within the hair waving apparatus'maybe raised. A Another object of my invention is to provide a practical construction of-casing for a heater employed in a hair waving apparatus where the parts of the casing may be molded inexpensively on a quantity production basis and connected one with respect to the other forprov'idin' a substantially shell-like. enclosure for a eating element, protecting the patron and operator against burns due to hi h temperature; 7 till another object of my invention is to provide a construction of casing for an electric heater for hair waving in which 2. casing of shell-like construction is provided, with ventilating means disposed in one portion of theshell-like casing, the casing having means for interconnectingthe portions thereof to provide a heat-resisting enclosure.

A still further object of my invention resides in the construction of a casing for hair waving apparatus, wherein the heater memher is in the form of a cylindrical device, with means for preventing the leakage of 'condensate from the casing, thereby preventing injury to a patron during a hair waving operation. c

Other and further objects of my invention hair waving apparatus in which the casing is formed in two parts related one to the other for compactly housing a heater member, as more fully set forth in the specification hereinafter following by reference to the accompanying drawings in which:

Figure 1 is a side elevatlon of the hair waving apparatus of my invention; Fig. 2 is a vertical cross-sectional view taken through the hair waving apparatus of Fig. 1; Fig. 3

is a cross-sectional view of parts at the casing disassembled position preparatory.

to an vassembly operation; Fig. 4 is a aC-I DSS- sectional view taken through "the heater and easing on line of Fig. and Fi .15 is :a cross-sectional view taken zthrou e hair waving apparatus on line 5' 5 of Fig. 2.

Referring to the drawings .indetail, reference character 1- designates the upper por-.

'In the upper end of the shell 1 there is pro vided an annular p0rtion'6 which terminates in a head portion 7 withan aperture 8 therein. This cone shaped undersurface acts as a guide for rod 24 making insertion of rod 24 in aperture 8 quick and positive. The aper ture 8 holds rod 24 exactly in upper portion of the heating chamber.. The cone sha ed head 7 forms a closed steaming tube a er rod 24 is inserted in'aperture 8. A slightly larger diameter to aperture 8 over diameter of rod 24 allows for the necessary escape of the steam. The casing 1 is provided with offset port- ions 9 and 10 on diametrically opposite sides of the casing which serves as entrancesfor the conductors which connect with the electric heater enclosed by-thecasing. The shells 1 and 2 are molded from insulated material which offers large resistance to heat. The lower extremity of the shell 2 is provided with an inturned flange 11 which is shaped at 12 in such manner as to support the cylindrical heater structure 15.

The electric heater shown at 15 may be formed in any desired manner. I have illustrated the turns 14 of resistance wire embedded in afsuitable refractory or heat-resisting material shown at 16 and forming heating means between the walls of the cylindri+ cal member 15. A ring member 30 is positioned interiorly of the casing 1 and provides an abutment against which the upper ex tremity of the cylindrical member 15 contacts. The heater structure is assembled as shown, I have shown conductors 21 and 22 passin through the entrances 9 and and lower portion of the heater provides a guide on which the hair of the patron is wound during a hair'waving operation. The plate projecting lug 31 and shifting the member 25 has a plurality of heat-resisting projections 26 thereon which connect to heat-.. resisting plate member 27 which is covered on its lower surface by means of a pad represented at 28. An aperture formed in pad 28 and in plates 27 and 25 permits the strands of hair represented at 29 to be passed into the heater and locked in position by rotative movement of the plate member 31 by rotatively moving the plate 31 by grasping the ug with respect to the lug 25*. In order to prevent any dripping of condensate from the heater, I provide a plurality of absorbent gaskets 32 positioned on theplate member 31 as shown. The strands of hair are wrapped upon the central rod 24 by means of the heat-resisting winder member shown at 33. This winder is set forth in more detail in my co-pending application SerialNo. 263,493, filed March 24, 1928, for permanent hair waving appliance. A wrap er is provided as represented at 34 for hol ing the necessary softening solution for steaming and protecting the hair against excessive heat, and a clamp having a pair ofarms represented at 35 secures the wrapper in place. The clamp 35 is provided with a bridge member 36 at the upper extremity thereof through which the central rod 24 passes. This clamp holds the wrapped assembly exactly in the center of the heating'tube, and also holds the lower portion of shell firmly against plate 31. This clamp 35 allows easy and instant withdrawal of the heating element and attached casing, from the hair without injury to the patron.

Itwill be observed that the heater is not in any sense locked to the head, which is prohibited by law in several States. By simply lifting the shell the entire assemblyand clamp is withdrawn from the heating element so that the patron may readily draw %way from the heater without injury to the air.

The spring tension obtained b operation of spring 35 permits the assemb y shown in Fig. 2 to be maintained in exact central position within the heater and 'held firmly against plate members 25 and 31' at bottom.

I have found the construction illustrated herein to be extremely practical, and while I have described my invention in one of its preferred embodiments, I desire that it be understood that modifications may be made and that no limitations upon my invention are'intended other than are imposed by the scope of the appended claims.
