PERMANENT-WAVE DEVICE.

Application filed May 27,

w This invention relates to hair waving devices and it refers more particularly to adin the provision of certain features of adjustmentin the construction of said core members, thereby enabling the latter to be moved to tighten the strand of hair thereabout, after being wound thereon for insertion intosaid heating oven.

Other objects of the invention reside in the compact, durable and economical construction of the core members embodied in the invention, as well as certain features of construction and arrangement of parts by which the said objects are attained, the assembly being described and manifested in the course of the following detail description and illustrated in the accompanying drawings wherein:

Figure 1 represents an elevational view of a core member unit constructed according i to the present invention.

Figure 2 is a similar view showing the adjustable features of the member.

Figure 3 is a cross-sectional view on lines 3-3 of Figure 2.- V

Figure 4 is a front end view of Figure 1.

Figure 5 is a rear end View thereof.

Figure 6 is a modified example of the structure disclosed in Figure 1, showing a variation in the method of adjustment.

Figure 7 is an enlarged fragmentary view of Figure 6, further showing the adjustable feature, and v I Figure 8 is a representation ofthe manner in which the invention is applied.

It is of course a well known precedent in the art of waving and dressing the hair, to employ a multiplicity of electrically heatedovens, in each of which is inserted core members about which the locks of hair are entwined in a manner to produce permanent undulations in the hair. In waving the hair by this method, it is necessary that the hair be entwined as tightly as possible about the core members during its subjection to the heating process in order to tho-roughly impress therein the curves of said core member. In this regard the present invention proposes to provide a core member capable of such adjustment.

Now, with the foregoing in view, attention is directed to Figure 1 of the drawings 1926. Serial No. 111,976.

wherein is shown a member 1 constructedv preferably of aluminum or its metallic equivalent of a substantially U shaped form, and having an elongated arm 1 which may serve as a handle. provided with a clip '2 on its end, the purpose of which will be later described.

A short arm 3, shown particularly in Figure 2 is formed integral with the body of the member 1, but which is of lesser diameter than the parallel arm. Slidable upon this arm 3, is a housing or shell 4,'which, when in place thereon present-s substantially the same shape as does the shaped portion of the paralleling arm, but which is so disposed as to have sufficient clearance, as shown in Figures 2 and 6, between the arm 8 and wall of the shell 4, as to permit of relative lateral displacement.

In Figure 2 is a .detailview of the means by which the shell 4 is adjusted with respect to the body 1, and which means consists in the present case of a squared shaft 5, adjacent either end of which is situated a cam shaped member 6, rigid with respect to the shaft. These cam members are placed in the position shown in Figure 2 and the shel 1 slid thereover and to enclose the arm 3, the projecting tongue 7 is then turned down against the shoulder a on the arm 3 to hold the shell against endwise displacement. After this is done, the key 8, provided with a box 9 is insertedover that part of the shaft 5 provided therefor, through the aperture 10 in the end of the shell and turned, the cam members engaging the interior wall of the shell,thereby moving the same outwardly to increase the width of-the member. Thus it is obvious that the hair, when entwined about the instrument, will become tighter through the action described, and a more substantial wave is the result.

lVhile the results attained through the use of the instrument illustrated in Figures 6 The member is further,

and 7 is identical to that just described, the

manner of obtaining adjustment is some what modified as shown. Referring to Figure 7, particularly, reference character 3 is likewise employed to indicate the arm performing the same function as in the former structure, and which when housed by the shell 1, presents the same surface and ap pearance as the previous structure. -However, the arm 3 in the present case is channeled at 11, as in Figure 7, and the opposite corners are angularly cut as illustrated,

at which point triangular members 12 conformably tit. A shaft 13 repos'es vwithin the channel 11, and upon the ends of which right and left hand threads are cut, in order, when the shaft'is turned by rotation of the key 8, detachably mounted on the shaft, the action will be to draw the triangular mein bers 12 towa"d one another, per s itting the same to be elevated by riding along the obliquely cut corners of the arm 3. "This being the case, the shell l, when in proper place on the arm, is elevated; to tighten the hair as before described.

In placing the hair on the instrument it is segregated into locks of the proper size and drawn over the shoulder as being passed through the clip 2;, and .se

cured, The hair is then passed about the same en the instrument, after which the.

latter is inserted into an oven of the usual construction preparatory to waving by the applicaion or electrical current.

It should be understood that while all of the elen' ents have been referred to specifically herein, certain minor changes and modifications may be resorted to, such as altering the shape oi the arms whereby to produce waves of; dillerent depths shapes without departing from thespirit or intent of the invention as set forth in the appended claims.

Vile claim-- 1. A hair waving unit including a substantially Ushaped memberone oi the arms ogt; which is smaller and shorter than its companion arm; a shell slidable over said,

smaller arm so as to be movable laterally with respect to said longer arm; a shaft interposed between said small arm and shell having means for engaging sa id shell; and,

means for rotating said shaft to force the shell outward to tighten the hair entwined about said arms.

A hair raving unit including a bifurcat'ed element in which one of the arms thereof is smaller than its companion arm; a shell arranged to be loosely mounted upon the smaller of said arms, a shaft interposul in Figure 8; and securely tied by the cord i l, the latter and betweenv said smaller arm and shell having means for engaging the inner surface of the latter, and means to permit rotation of said shaft to move the shell outward to expand the distance between the outer surface of said. shell and adjacent arm.

9. A'haiiwaving unit comprising a memher having twoarms, one of which is smaller than the other; a shell slidable over the smaller of said arms and having means tor. securing the same against displacement; said shell being of such size as to permit its, movement toward and away from the ail-1 8 cent arm, and means to cause such movement. r f i 4. A hairwaving unit comprising a mem her l'iaving two parallel arms, one of which is smaller'than the other; a shell for said smaller arm means to permit movement of said shell toward and; away from the adjacent arm; means to permit strands of hair to be alternately entwined about said shell and adjacent annand secured; and means to cause outward; meve: ment of said shell to tighten said; hair, about the members.

A hair waving unit including a substantially U shaped member in which one or the arms thereof is smaller than its co1npanion arm; a shell covering arranged to tit over said smaller arm and be laterally movable with respect to .Suld. companion arm; means to permit entwining of hair about said shell and companion arm and secured in such position; and means'intermediate the inner surface of said shell and smaller arm to cause thetormer to be moved outwardly to further tighten the hair en twined thereon.

6. In a hair waving unit for electrical waving apparatus including a substantially U shaped member in which one of. the arms thereof is shorter and smaller than its coinpanion arm; a shell arranged to enclose said sn'ialler arm and be movable laterally wound about said shell and companion arn and means to cause said shell to move outwardly to further tighten the hairOn said members.

In testimony whereof we atfiX our signatures.
