2 claims. (c1. 13e-'34) 1 This invention pertains to a device employed in the art of hair waving and more particularly to the novel construction of a rod upon which the hair is wound or wrapped'to 'impart permanent curls thereto.

`Various processes for imparting a permanent wave to the hair have'. been practiced for many years but these processes have depended primarily upon the application of electrically developed heat and required a, time cycle measured in hours. The newer hair waving methodshave been developed to eliminatethe necessity of the customer spending uncomfortable hours under .the electric hea-ter.

One of the more promisingof the newer processes is known as the cold Wave process. In this process the head of hair is sectioned oif andeach section is wound or wrapped around a small diameter rod to form curls. The number of rods required depends upon'the ease or difliculty with which the particular hair curls but in general approximately thirty rods are required to wave the average head. The curling rods are provided with a metal spring, or elastic band which can be snapped over the curled hairto maintain the hair in the curled state and to retain the rods in suspended position about the scalp. After all the hair is curled around the rods, the operator applies a preferred chemical solution to all the individual curls either directly from a bottle or by means of a small brush, cotton dab, or etc. The entire head is then enclosed within a suitable cap for approximately thirty minutes during which time the chemical solution reacts with the hair to impart a permanent Vwave thereto.

The cold wave process has not met with universal acceptance and I have found that the main reason for a large percentage of failures is the inability of an average operator to properly wet the individual hair strands with the chemical solution. I have found that to produce acceptable results all hair strands must be completely and uniformly moistened by the solution but there exists at present no certain way of accomplishing this. Inasmuch as each curling rod contains a bundle of hair curled into a mass several inches long and approximately an inch in diameter, it

is apparent that the normal methods of moistening the mass externally do not permit penetration oi the solution to the inner layer of hair strands.

Consequently, the inner hair curls do not receive a permanent set and as these inner curls are the extremities of the' hair the completed job is not at all pleasing to the customer. Experienced operators have developed personal knacks which 2 make it possible to produce a practical percentage of acceptable waves but theaverage operator soon becomes discouraged andreverts to the old heat process.

A curling rod made in accordance with my invention makes it possible for inexperienced operators to completely and properly moisten the hair thus assuring good results.

An object of this invention is the .provision of -a hair curling rod which is adapted for use with a small handv syringe whereby the hair waving solution Ais applied lto thev hair under pressure thereby assuring even distribution of the solution. Y,

An object lof thisinvention is thev provision of a hair curling rod havingan axial bore in one end thereof and connecting with longitudinalslits' inthe body of therod whereby liquid forced, into the :bore vwill seep out through ,the slits substantially along the entire length of the rod.

An object of this invention is the provision of ahar curling rod provided with a, relativelyyheavy washer rotatably `secured near one end thereof and a flexible rubber strap looped through the rubber washer in such manner that the strap may be stretched across aY band of hair curled around said rod to retain the hair and rod in fixed position on the head.

These and other objects and advantages will be apparent from the following description when taken with the ,accompanying drawing which illustrates one embodiment of the invention. The l drawing is for purposes of illustration and is not to be construed as defining the scopes or limits of the invention; reference being had for this purpose to the appended claims.

In the drawing wherein like characters identify like parts in the Various views:

Figure l is an isometric View of a rod made in accordance with my invention; f

Figure 2 is a central cross-sectional view of rod shown in Figure 1; Figure 3 is an isometric view of the rubber washer; n l

Figure 4 is an isometric View of the rubber strap; y

Figure 5 is a front `View of the rod showing the rubber washer and strapassembled thereon; and l Figure '6,is a View of the complete rod showing the hair curled thereon, the strap in its hair retaining position and the manner of injecting liquid into the rod by means of a hand-syringe. v

Referring now to Figures 1 and 2', the numeral I0 identifies a rod of generally concave form,-

V.that is, having a progressively increasing,ycir

cular cross-'section from the center toward each end. This rod may be made of plastic, metal or Wood and includes an integral extension II of reduced diameter at one end and a circumferv ential groove I2 lat the other end. A thin longi` tudinal slit I3 extends completely through the rod said slit being in direct communication with a central bore I4. It is apparent that :liquid forced into the bore I4.Wil1 oW out of the slits' I3 under considerable pressure. I have found @to retain the rod in the desired position during that a Single slit as described is sufcient forl practical purposes but it is obvious that a plurality of slits may be used.

Figure 3 illustrates a relatively thlckrubber Washer I5 having a hole I6 that' isof a diam'- groove I2. over 'the rod toloosely occupy the groove I2 Vas shown in Figure 5; the Vrod `and Washer being readily rotatable one relative to the other. The Washer l5 also includes an integral extension I'I having an opening I8 cut or punched therein for purposesdescribed below.`

"YA' pliable rubber strap Y1I9 of the general form shovvn in Figure 4 includes a hole 20 at one end and a hole 2| at the other end. In assembling my complete hair curling rod, the end ofy strap I9 is forced through the hole I8 in'rubber Washer I5 and loopedthrough the hole 2D to form Y. eter somewhat larger than thedameter sof/the y;

rod I at` the bottom of the circumferential. y

Thus, the Washer I may be forced spirit of the invention as set forth n the claims.v

By as` sembling rthe strap and washer in lthis manner the vstrap has a normal tendency to extend to the rright as shown and' may, therefore, be convenientlyheldiby the operatorin the palm of the right'hand. vvvThus held the rod I0 may readily be rotated byfthe fingers of the left hand during the act lof'wrapping hair. around the rod. When' the 'waving solution into the rod.

With the hair retained in curls around the rod the operator inserts the nozzle of a small hand syringe 22 into the bore I4 and forces a chemical hair emerges from the slits I3 and being subjected to considerable pressure the liquid oozes throughfout the entire mass `of hair completely moistening all individual hairs. 1

'Having noW described my invention various changes may be madein the construction of the parts without departing from the scope and I claim:

1. A hair curling device comprisinga rod having an integralextension of reduced diameter at one end and provided with a circumferential groove at the other end; a, relatively rigid washer rotatably disposed Within said groove; and anexible strap .having a hole near each end thereof,

said strap detachably securedto the said Washer and adapted to be stretchedacross the rod and looped over the integral extension of the rod on the opposite end thereof. Y Y

2. The invention as recited in claim 1 wherein the rod is of concave form having a progressively increasing diameter from the center Vtowardrthe Vends.
