Patented Aug. 28, 1934 UNITED STATES .PATENT :o1-FICE y HAIR 'rnmrrrits.v `over: i Burney-J. Balmer, Kansas GtypMo. Application Angustias, resa'se'rial 10.681137 13 claims. (crise-ss) This invention relates to hair wavingimachines, and particularly the clamp and oven assembly which is used to directly apply heat to strands of hair whichare wound upon the well known 3,5 hair-receiving spools, and the primary object of this invention is to provide a unique and novel khairtreating oven wherein the hood thereof is `positively ailxed to the vise in such manner that :the jaws of the .viseare maintained against accidental` displacement during the application of .heat and the seal betweenvise and hood is unbreakably established. -v .1 o

Another object of the present invention is to `provide a hair treating ovenfor permanent wave 13715 machines using steam as a heating element having aimoisture-absorbing gasket `that is formed in a particular manner so as to present a condensate absorbing element within the oven that `precludes the` collection of moisture at any time.

Further specific aims of, this invention will appear during the` course of the following specification,referring `to the accompanying drawing,

wherein: i l

` Figure 1 is a side elevation of a hair treating 25 oven made in accordance with this invention.

Fig. 2 is a longitudinal cross section through the same, taken on line II--II of Fig. 1. Fig. 3 is an end plan view of the completely assembled oven. c c

Fig. 4. is a4 vertical, central, cross section through thev oven.

Ydetailedviewthrough one end of the oven, showin'gl the specic manner of constructing the 35 clamping element. l

f Fig. 6 is a top plan view of the vise forming a part of the ,unique oven illustrating the articulated strips thereof in a separated position. Fig. '7 is a vertical, central, cross section V40 Vthrough the oven with the special gasket for absorbing condensate in place, and, U Fig. 8 is a'plan View of the gasket entirely'removed from association with the oven and in the blanked-out form. 'y

Figs. 1 to 5 inclusive illustrate `the hair "treating oven `without the novelgasket associated therewith, it must be understood that the gasket may be applied without altering" the `structure of the oven in lanyf manner whatsoever and this 5,0`gasket might be used or" not, as `the-operator ideems advisable.` i i Inpreparing the hair for a permanent wave, same is blockedoi `and the vise shown in Fig. 6 appliednear the scalp so that the free ends o the ...5.5 hairg might `be wound around spool 10 whichl-is To'preolude this condensate Vthe scalp, a moisture-absorbing `gasket 48 is con- 1 00 rotatably supported by this vise, thatcomprises a pairof strips 12, each covered by a jacket of resilient material 14 which, when the strips 12 are drawn togetheras'shown in Fig. 4, will grip the strandswof hair therebetween to positively preclude slipping. Strips 12 are hingedly secured together at one end by a link 16 and asimilar link 18 at the other end of strips 12 supports a manually operable latch member 20 that co-oper- `ates with a notch 22 formed in one strip 12 for 65 the purpose of securing togetherboth strips 12 after the hair has been passed therebetween.

In the instance shown, each

link

16 and 18 respectively is i U-shaped in transverse cross section and at least one wall thereof is provided with a tapped opening 24 for the reception of a hereinafter described screw-threaded clamping element. f Y i Link 16 is likewise provided with a tapped opening 26 for ra similar purposeand strips 28 .'16

and `30 rigidly secured to the jaws of the vise present1 tongues 32vand 34 respectively which combine with rims 36and 38 of spool 10 to rotatably secure said spool in place. Tongue 34 progressively engages detents 39 as spool 10 is 80 rotated and precludes unwinding of the spool after the strand of hair has been tightened thereon. As is customary, aclamping finger .40 is .providedron spool `10 so that the ends of .the

strand :ofhair beingwound might be secured es in place before the spool is rotated.'

A sheet metal hoodV 42 is carried by strips 12 i and joins with the latter in completely housing 'spooll and its associated parts. This hood 42 must be secured `in place with sufcient force to prevent escape of air therefrom because steam is applied to the hair wound upon spool 10 by passingthe steam intointake port 44 that `is :formed `throughthe boss and side wall of hood 42. An-

other similar boss 46 provides an exit :for the A95 "steam inorder to set upV complete circulation and `obviously a certain amount of .condensation will take `place duri-ng the operation. Y

from contacting templated. This gasket 48 may `loe made of ordilnary blotting paper or similar substance and.

should be formed'a's distinctly illustrated in Fig.

A`8; `gasket is applied before hood 42 is moved to position and underlies the edgel thereof. In

' other words, it is-interposed between hood 42 and f the .resilient material which circumscribes strips -1`2i Walls`150 are set off on the normally planar gasket 48 between openings 52, one of which is formed through the gasket adjacent each -end. 110

which effects connection between vise and hoods.

The unique manner of interconnectingvhood 42 with strips 12 is embodied in the clamping ele,

ment 60 that has a knurled head 62 preferably formed of iibrous material that ductor of heat. A screw-threaded shank 64 exe tends through bearing 66 that is rigid with hood 42 and this bearing permits' free -rotation of the entire clamping element 60. Shank 64 extends into tapped opening 24 of link 18 and a collar 68 secured intermediate the ends of shank 64-limits longitudinal movement of element 60 in bearing 66.

Openings 70, formed through the walls of bearing 66, are not tapped and the end of shank 64 is tapered as at '72 so that the clamping element 60, one of which is located on each end of hood 42, may be quickly moved to the operative position so that it will draw hood 42 down against gasket 48 or resilient covering 14, as the case may be. Tightening these clamping elements will set up a positive seal between parts of the hair treating oven and when steam is passed through the oven no leakage will ,occur and a quick disassembling may take place merely by unscrewing clamping elements 60. Insulating strips 74 are provided to insure that no objectionable heat will be conducted from the oven to the scalp,

An oven for treating hair that is made in accordance with the foregoing will be found to be positively assembled when the hood is in place. No accidentalopening of the vise can occur because the hood vand its associated clamping ele- Yments will preclude moving apart of

links

16 and 18. Any suitable materialsv might be used in constructing the parts of thevoven, but it has been found that rust-resisting metal is best in forming the metallic parts of the oven.
