Y., a copartnership' Application February 22, 19i5,:.fgmwm 579344 (ci: razr-'say The invention relates toimprovementsineurlingirods, and morerparticularly toa novelly constructed curling rod of a kind especially useful in the process commonly referred to -as-cold vpermanent waving. e

In permanent wavingof human hair and-particularly in the practice ofthat'typeof-permanent waving known as cold permanentwaving, the hair on: the head isY divided into any required number of individual vtresses yand said tresses are e then individually woundupon curling rods. fl'fhe woundtresses of hair then arelthoroughly saturatedfwith a permanent Waving` solution Awhich acts toY softenA the hair or otherwise condition it so that it `will conformto itsleurled condition. After the waving-solution hasbeen allowed to act upon vthe hair tress lfor al predetermined period of time depending-upon the kind of hair being treated; the waving y solution XAis washed out of the wound hairtress Awith water or other like yneutral solution.- When the wavingsolution is` removed from the Wound tress, the vlia-ir then regains# its initial structuralcondition andv when dryV and removed from the curling rod it will remain in the wound position to thereby produce the desired-curl.

In ypractice it-has been found that vsatisfactory results'canbe obtained by. theuse ofvthis method of cold permanent-waving only-Whenfthe waving solution and the neutralizing solution haveybeen .permitted to -penetrate to theinnermostj strands .of hairof-.the wound tressto thereby effect com plete saturationthereoi In instances vwhere-such Kcomplete saturation of allofthe hair inthe wound tresses is not obtained,Vlr the finished curl -K fre- -quently has portions thereof which doynotretain the `wound* condition and consequentlyv the re- Vsulting curl'is imperfect, andthehai-r tresses va Awhole is-non-uni-forin.`

Itis, therefore, lan object of the present invention vto provide a curling` rodnof the kind refer-red to, which isconstructed in i-.manner to facilitate Vcompletepenetration of thef waving and neuwaving-.land neutraIiZingsOItiCns to flow freelyvtherethrough and throughout-.the body of a hair tresswound thereon.

Thecurling I rod embodying features of the present inventionand illustrated in Figs. 1 to 4, inclusive of thevaecompanying `drawings consists of ia bpdyportion generallyindicated at Il and a -holderj .gene rally indicatedat l2.4 The body portion# l `yis;fashioned-gin the form of @substan- -55 tiallycage-like structure includingcircular end walls I3 and I4 connected together by a plurality of bars I5. The bars I5 preferably are formed of lengths of relatively stiff shape-retaining wire or thin rods having their ends firmly secured, as best shown in Fig. 4, into the end walls I3 and I4 respectively, as by riveting their ends as at I6. In the form of the curling rod body illustrated in these figures, there are three rbars I5, each of which is suitably curved or arched lengthwise so that the intermediate portion of the body II formed in part thereby is of a diameter considerably smaller than the diameter of thecir-r 4 end 26 fitted over a, boss 21 provided on the outside face of the end wall I4. The boss 2l preferably is suitably recessed oircumferentially, as at 28, to receive the strand and prevent inadvertent displacement thereof. It might be noted at this time that the boss 2l is useful to facilitate grasping of the end of the curling rod, upon which it is provided, during the Winding operation.

Prior to securing tliev'vound tress of hair to the curling rod by means of the strand 25, the holder `I2 is removed from the body II as by withdrawing the same from engagement with the stem 23,

cular end walls I3 and I4. This mode of con-V struction is desired primarily because when the tress of hair is wound upon the body, said tressl tapers downwardly and outwardly towards its ends as the winding increases, consequently the reduced medial diameter of the curling rod `prevents excessive building up of the hair tress` at' the longitudinal center of the curling rod.

The curling rod body II is adapted to include a fourth bar II which likewise is formed of thin shape-retaining wire or of a thin rod, and this bar isV mounted in the'body end walls I3 and I4 Vfor easy separation therefrom or attachment thereto. The bar Il'is of greater length than the over-all length of the curling rod body so that one end thereof, as at I8. may be rmly embedded in and secured to a handle portion I9 of lthe holder I 2. Thus it will be'seen that the bar Il and handle portion I9 constitute the holder I2 and that said holder may be associated with the body II in a' manner to be described presently so that the bar I1 thereof constitutes a comple-Y n 2I. When the bar I'I is properly Ypositioned, in'

the hole 2I and recess 22, it is-heldagainst `in- -advertentdisplacement by an interlocking arrangement provided on'the body II and handle portion I9. As shown. the end wall I3 is formed on its outside face with an axial stem 23 adapted to be received within'an axial recess 24 provided in the end ofv the handle portion I9 carrying Vthe bar Il. -To assemblethe holder I2 and body II,- the recess 24 is fitted over the stem'23 and the holder then is moved towards the body portion until the free end of the bar I'I engages in the hole 2l in the end wall I4. When thus assembled the curl'- 'ing rod body includes the three arcuate barsY I5 and the' straight bar II which together deli-ne, in section, a substantially diminishing tubular body as the medial portion thereof is approached. In use, the free end of a hair tress is held or which removal also withdraws the bar I'I from the body II and from Within the wound hair clamped against the medial portion ofthe body Y Vns as during the initial winding.

tress. The free end of the strand 25 is apertured as at 29, and this' apertured end is engaged over the now exposed'stem 23, as best shown in Fig. 4, to .thereby prevent the wound tress from unwindirl g.

eremcval of the bar- Il from the body Il enables It should be observed upon viewing Fig. 4 that the Wound hair tressy to become comparatively loose upon the body II, While at the same time it retains its Wound condition. This looseness of the wound hair tress is necessary to satisfactory Apractice of cold permanent waving because'of the need for effecting complete saturation of al1 of the strands of hair in the wound hair tress. Such saturation obviously is exceedingly diiiicult and 30.

frequently impossible to -attain when the hair tress is wound tightly upon the curling rod body The cage-like structure of the body I I also facilitates thorough penetration and complete saturation of the hair tress because of its open construction which enables'the solutions to flow freely throughout ythe entire bulk of the wound tress and through the Ainterior of the curling rod body, as when an excessive amount of the solutions flows from the 4uppermost portion of the Wound tress through -said cage-like body and down onto the lower interior face thereof.l After the curl has been `treated-With the Waving, solution and with the The curling rod shown in Figs. 5 to 8 inclusive,

sponding parts'. However, in this embodiment of the invention at least one of the bars I5, such as for! example the one identiiied as I5a, is mounted -in the end walls I3 and I4 in such manner that it may be shifted into various positions so as to decrease the tension onthe wound hair tress to thereby enable said tress to'acqulre the desired looseness. As best shown in Figs. '7 and 8 the bar Ilia has its'ends engaged in cam-like slots 3| formed on Athe inside faces of said end walls.

,'Each of the slots 3I includes a, radial portion 32 and a circumferential portion 33 and is suitably formed at the juncture of said portions 32 and33 with a detent projection 34. The slots 3I are of su'ch width as to snugly receive the ends of the bar lia and when said bar is in its outermost position, as best shown in Fig. '7,Vits ends rest in the circumferential portions 33 of said slots to dispose the bar substantially in the same circumferential plan as Vthe fixed companion bars-I5 `and removable bar I'I.-l The hair tress is clamped to the curling rod by clamp' 2li` and then is wound upon the body of the curling rod while the movs 'atie bar-fis in this positionlifter-themen tress has been funy'weune thereon and the holdem-z isremovedf towithdfraw tne'bar' yf1 ffr'om within curl', the bar 'Fia is moved past'"thev detent projection 3,42, in `'each slot, y:so Athat' it'maydrop into the slot-portion 32 -so as to further 'increase the looser'iess v'of thehair'tress woundf-on said'rod. lThe' clirlhg'lod' illiistfrfedin Fig. 9 is Substan- `tially like the curling Yrods 'previously described *corresponding perfs.
