(Cl. 132-36) ‘This invention relates generally to permanent hair waving machines utilizing steam or like con Fig. 2 is 'a side elevational view of the machine shown in Fig. 1. densable vapor as a heating medium. I Fig. 3 is a cross-sectional detail taken along the . The use of steam as a heating medium in per lines 3—3 of Fig. 1. ' ' manent waving machines has certain advantages The machine as illustrated in the drawing con over the use of electrical heating elements, par sists of a steam conduit H, which is preferably ticularly in that steam seems to impart a softer loop-shaped or substantially circular, as illus wave, without a drying-out of the hair at the trated 'in Fig. 1. The rear side of this loop has end of the waving operation. Likewise, by the a short pipe connection I2 to the vaporizing ll) use of steam, the temperature to which the hair - chamber of a steam boiler 53. The boiler in 10 is heated is de?nitely limited. Steam machines turn may be supported by a suitable adjustable such as have been used in the past have not been and portable standard It. While the plane of popular, for the reason that the devices utilized for applying the steam to the wound hair have been cumbersome, and it has been di?icult, if not impossible, to treat a complete head of hair in one the loop formed by conduit H is generally hori zontal, it is preferably inclined at a slight-angle, as shown in Fig. 2», so that steam condensate can 15 drain back through the pipe connection [2 into the vaporizing chamber, and to facilitate distri such machines has been that steam condensate bution of steam through further elements to be has not been properly taken into account, so presently described. Heat insulation 15 is pref that the'heating effect has been insu?lcient to erably provided to minimize dissipation of heat. 20 Various types of boilers can be utilized with the produce the desired wave, or has not been uniform ' with respect to di?erent curlers, or an excessive machine, and therefore the particular boiler il steaming operation. A further disadvantage with ' amount of hot steam condensate has been per mitted to drain upon the scalp. Di?iculty has also been experienced in securing proper distribu tion of steam to a plurality of devices upon the head, thus causing the time required for the com plete waving of a head of hair to be unduly ex tended because of the necessity of carrying on 30 successive heating operations upon separate groups of waving devices, in place of supplying a complete set of waving devices with steam in one operation. 4 I It is an object of the invention to provide a per manent hair waving machine utilizing steam as a source of heat, which will overcome the above difficulties and which will make possible the heat ing of an entire head of hairby steam in a single operation, in a simple and effective manner, 40 without discomfort to the subject. In connection with the machine described herein, it is preferable to utilize hair waving ‘devices of the type dis~ closed and claimed in Patent No. 1,984,585, grant ed December 18, 1935, which are a marked im provement over the cumbersome forms of stea boxes utilized in the past. ‘ Further objects of the invention will appear. from the following description in which the pre ferred embodiment of the invention has been set forth in detail in conjunction with the accom panying drawing. . Referring to the drawing: charge, and for entraining water, whereby the steam is relatively dry. Where the pipe I2 com municates with the vaporizing chamber, a suit able valve is preferably provided, to be operated by handle it. This valve is arranged to have two 30 operating positions, in one, of which the vaporiz ing chamber is placed in communication with both pipe l2 and an auxiliary steam exhaust con duit I1, and in the other position of which the‘ auxiliary conduit I? is closed so that all steam 35 is discharged through pipe l2 and into the con duit Ii. In order to simultaneously apply the steam to a ' plurality of hair waving devices, ?exible tubes l8, formed of a suitable material such as resilient 40 vulcanized rubber, communicate at circumferen tially spaced points with the conduit ll . For ex ample, as shown in Fig. 3, the end portion I9 of each rubber tube I8 is enlarged and is slipped over a stub tube 2|,which in turn communicates with conduit H. -The tapered nature of the enlarged resilient rubber portion l9 tends to pre vent kinking of the tube [8, such as would ob struct the same for ?ow of steam. All of these tubes are preferably of the same length, toaf ford paths of equal ?ow resistance- r The free end‘of each of the tubes l8 can'ies , Fig. 1 is a plan view illustrating a machine in corporating the present invention. lustrated need not be described in detail. In general, it should include means for superheating the steam to a suitable‘degree before its dis 25 a steam condensate trap 22, in conjunction with means for coupling the same to a hair waving device. The form of steam condensate trap illus 55 2,115,076 trated consists of ~a hollow body formed of two sep - I‘! in communication with the vaporizing cham arable parts 23 and 24. These parts may be made ber. This serves to substantially arrest the flow of steam through conduit II and the ?exible of a suitable material, such as a phenolic con tubes iii, to facilitate making connections with densate product, and are shown connected to 5 gether by threads 26. One end of this body has the hair waving devices H. The operator now an extension tube 21 over which the free end of successively detaches the steam traps from the tube i3 is engaged.

In doing this of the body there is a tube 28, the outer end por tion 28 of which forms a means for detachably it is of course necessary to turn the steam con 10 coupling to the steam ‘jacket 3| of a laair waving densate traps to substantially upright positions, 10 device. Surrounding the inner portion of tube ~ in which, as has been‘previously explained, they catch and retain steam condensate. _After all of 28 there is a substantial space or pocket 32 for the hair waving devices have been properly cou-v ' the accumulation of steam condensate. Both the inner and outer ends .of when are terminated pled to steam condensate traps, valve handle [6 is 15 or cut off on a bias, as indicated at 33' and 34, again _ turned to close the exhaust conduit 11, since this construction‘ has been found desirable ' thus causing all of the steam to be delivered in draining away condensate, thus avoiding to conduit I l and from thence through the tubes l8 and the steam condensate traps to the hair ' blocking of the ends of the tube 28 with drops of water.

'Operation of the device is as follows:-The operator ?rst prepares the head of hair by ap ment of conduit II,v together with the forma tion of the steam condensate traps, also insures plying protectors to-the hair strands and by fort of the subject is promoted, because of the a proper distribution of steam to the various hair 60 waving devices, without utilizing steam pres sures materially above‘ atmospheric, ‘and with relatively short rubber tubes l8.‘ Thus, relatively uniform heating is secured' with respect to the several hair waving devices, with the production 55 of relatively uniform waves over the head.
