This 'invention rei'ates to devices for Wavinghair. on the.. human head, and particularly" to an' improved hairwaving' d'evice of the" type' employing an exothermic' heating` element'.

' The primary object of" the present'inventi'on is" ti: provide a: hair' Waving device' of" the abovementibned'type' which' is simple in construction; convenient' tense; and eicientin use.

A: further-object" isto'provide" a device of the' above* i 'ind' emb'odying a casinghaving' a lower crlin chamber and an` upper' hot' vapor' gener atihg chamber, and" simple means to* center' the' heating element; in the' heat generating' cha-mber and to conduct the' hot' vapors from the iatter' chamberto'the'curiing'chamber.

Another' object" is` to' provide' a d'evce' of" the abovekind' in' which* a" heat sh''eld: for clamping' the hair' adjacent the' scaip* forms' a' removable bottom' for* the curli'ng chamber.

Referring in detail to the drawings, the illustrated embodiment of the invention includes a casing constructed of durable heat-insuiating material to provide a lower horizontaily elongated portion 5 whose interior forms a, curling chamber a, and a vertical cylindrical upper portion 6 disposed intermediate the ends of portion 5 and whose interiorforms a heat or hot vapor generating chamber b.

Fixed to and* rising';` from' thepiate IB' arerigid pawis z's' the purpos'e of which will 'be' presentlydescribedi The" present device' also includes a curlr* 2-9* a'dpted to' have aibcl'of' hair 'wound' thereo'r-and provided* with" the usua clamping lve'r' 30; The:

enl'arged circular" ends- 31' of" the curier` have" ratchet teeth 32 'cut in the peribhe'r-ies ther'e'o'fl` which'` teeth are adapted to be engaged* by the hair: may b'e wound thereon, as usual' and winding of th hair is prevented by engagement of pawls 28 with the teeth 32 of the curler. At one end. the curier 29 has a polygonal socket 33 for reception of the polygonal shank of a key used to turn the curler. i

A vertical tubular post 34 is rigid with the top of the body 'I and projects into chamber b centrally of the latter. This post provides a passage 35 which affords communication between the top of chamber b and top of chamber a.

To generate heat by Chemical reaction, I provide an exothermic heating element 36 which is a cylindrical Cartridge having an axiai opening 31 to snugly fit over the post 34, and which is of a size to leave a space between the same and the side and top walls of the chamber b` when placed in the latter. As shown, the element 36 preferably consists of a strip of absorbent material 38 provided with a backing strip 39 and containing a suitable Chemical, such as calcium oxide, the strip 38 and its hacking strip 39 being wound in a roll or coil.

In using the present device, the shield 8 is opened andthe lock of hair his introduced between the plates i& and I!) of said shield as shown in Figure 9. The free end of the lock of hair is then secured to the curler 29 by lever 30, and' further, the hair is placed under tension and it is so held by the pawls 28 which are engaged with the ratchet teeth 32 of the curler so as to prevent retrograde turningjof the curler. The body is then placed over the curler and latched to the shield 8 by catches 13. The element 36 is then dipped in fluid and placed chamber b, whereu'pon the cover n is .closed and'latched in closed position by the catch l2. The'reaction resulting from the application of moisture to the calcium oxide or the like generates sufficient hot vapors within the casing chamber b to effect permanency of the wave, such vapors passing from chamber b to chamber a, through passage 35. At its ends, the' body T has small inclined vent openings 40 through which excess or spent vapors may escape from chamber L in a direction away from the scalp. The vapors enter chamber a midway between its ends' and flow to the ends thereof, thereby supplying the greatest heat where mostneeded.

From the foregoing description, it is believed that the-Construction, manner of use and advantages of the present invention will be readily understood and appreciated by those skilled in the art. Modifications and changes in details of Construction are contemplated, such as fairly fall within the' spirit and scope of the invention as claimed. i

Having described the invention, what' is claimed as new is:

1. A hair Waving device comprising a casing having a lower horizontally elongated portion whose interior forms a curlng chamber and a vertical cylindrical upper portion disposed intermediate the ends of said lower portion and whose interior forms a heat generating chamber, said lower portion comprising a hollovv open bottom body and a heat shield which clamps the hair adjacent the scalp and forms a removable bottom closure for said body, said upper portion including an open top body integral with the first named body and a cover section for said open 4 top body provided with means to secure the same in closed position, upstanding pawls carried by said shield, and a curler removably disposed in said curling chamber upon said shield, said curler having peripheral ratchet teeth at the ends thereof adapted to be engaged by said pawls for holding the curler against retrograde turning movement so as to maintain a lock of hair wound thereon under tension when passed through the shield, said casing having a, vertical tubular post within the heat generating chamber providing a passage for flow of heat from the heat generating chamber to the curling chamber intermediate the ends of the latter, and an exothermic heating element disposed within the generating chamber and fitted over said post.

2. The construction dened in claim 1, wherein the casing has outwardly and upwardly inclined vents in the ends of the 'first named body for the escape of excess or spent heat vapor in, a direction away from the scalp.

3. A hair Waving device comprising a heat shield adapted to clamp on a lock of hair adjacent the scalp, a hollow body closed at the bottom by said heat shield to form a curling chamber within said body, means detachably securing 'said body to said heat shield, an open top body .carried by the first named body and having a cover provided with means for latching the same in closed position to form a heat generating chamber with in the second named body and said cover', means affording communication between the top of the heat generating chamber and the top of the curling chamber intermediate the ends of the latter, and an exothermic heating element disposed in said heat generating chamber, the means affording 'communication 'between the chambers comprising a tubular post disposed centrally of the heat generating chamber, said heating element having a central opening to snugly fit over said post.
