Application August 8, 1947-, Serial No. 767,481

6 Claims. 1

This invention relates to. improvements in hair curling devices and more. particularly to devices of the type disclosed. in my Patent No- 2,421,008 of May 27, 1947,. which are intended for use in the cold. set or roller method of hair curling.

In. the usual cold set method of hair curling,v the, hair ends. become unset and loosely curled: sooner. than the main body of the. roll, thereby necessitating a resetting of the entire coifiure. Also, the conventional type of rollers may be: fixed only in positions along: the hair length a. half or full revolution apart, and. when held close to the scalp, will draw the; hair so tightly as to cause extreme discomfort, while the next position. will leave a slight. uncurled length. of hair.

While the device of my prior patent overcame.- these. difiiculties, it. relied solely' on the retractable U-shaped wire member for its. locking function, while the finger member which clampsagainst the main portion of the curl was not. held ina fixed position and could workloose on the curl-..

It is a primary object of this invention. to provide: a cold set hair curler which produces more, tightly coiled; hair ends than in the remaining; length, thereby increasing the effectiveness of the treatment.

Another object. of. the invention is to provide: a. positive.- locking arrangement in. a hair curler of the. cold set type, which effectively holds both the finger portion. and the wire clamp. of. such a. curler against movement.

A further object of the invention. is toprovide. a. positive locking arrangement: which. permits fixing; sucha curler in adjustable and selectivepositions. along a strand of hair.

Other objects reside innovel details ofconstruction and novel combinations and arrangementsof parts, all of which will be described in. the: course of. the following description.

In the drawings, in which like parts have been designated similarly,

Fig.1 is-a perspective view of. a hair'curler ems bodying features. of the present invention; and showing the position of. the hair strand, by dotted line representation;

Fig. 2 is a side elevation: of the, curler shown. in Fig. 1 with the retracted. positions. of the. mechanism. and the hair strand. position indicated. by. dotted line representation; and

Fig. 3 is a. developed. section taken along the line. 33,. Fig; 2..

Before. describing the details of the present invention, it. is to be understood that the inven- .tion. is. not limited. in its application to the details. of construction and arrangement of parts.

illustrated in the accompanying drawing, since the invention is capable of other embodiments and of being practiced in various ways. It is to be further understood that the. terminology employed herein is for purposes of description and not in limitation as it is not intended to limit the invention. except as set forth in the appended claims.

The curler shown in the drawing preferably comprises a tubular body portion 4, the cross section of which progressively narrows from a point adjacent its respective ends 5 and 6- to a central point, and has at intervals throughout its length a series of apertures l. A. recess 8 is provided at end 6 to receive an extension on a finger member 8 whichis folded back upon itself to-provide a pivotal attachment of the member on the body as shown at Ill.

The finger member 9 has its greatest width adjoining pivot 19 and terminates at each side in at least one and preferably two rolled portions adapted to function as sockets I? for the reception of a locking wire l3, generally of U- shape and preferably having the outer ends of its leg portions flattened as shown at M- (Fig. 2) to prevent withdrawal through the socket members l2 after once assembled. Preferably, finger Si conforms in contour to the external shape of body 4 so that it will lie flat against said body throughout its length, and a series of apertures 15- are provided.- in finger 9.

The cross connecting portion of wire [3- extends laterally from the legportions and then loops in U or V formation It so that the lateral portions ll function asa stop-to engage the end 6 of body 4 while the loop It acts as a pull for manipulation of the wire in the manner to be subsequently described. At least one or prefera bly two. shoulders i8 (as shown) are. formed on the end- 6 0i the body portion to provide a rest for pull [6 when wire I3 is in its normally re.- tractedposition.

In the use. of the devicehe-reinbefore described; wire. i3 is. drawn from its completely retracted:

position a distance sumcient to move pull 1.6 out;

of contact with shoulders l8; thuspermitting the Wire to be used in rotating finger 9 so as to move it from the full line position to the dotted line position shown in Fig. 2. Astrand of hair suita bly treated with Wave solution. or otherwise prepared for curling is wound about body 4' and may be drawn as: tightly as desired, after which finger 9 is moved to the reclining position overhanging body 4 and the wire I3 is then moved into its retracted position with the pull [6 seated on shoulders l8 as illustrated in Fig. 2, in which position the rotation of finger 9 about pivot I is prevented by the aforesaid engagement of the pull with the shoulders. In this position, the leg portions of wire 13 also hold the outer surface of the wound strand in position and it is allowed to remain until the curl is sufiiciently set to permit removal of the device. The provision of the holes T in body 4 and IS in finger 9 insures suificient air circulation through the body and finger portions while the unit is holding the strand to permit rapid drying and evaporation of contained moisture.

Due to the clamping action of finger 9 when the wire is in its retracted position, the tightly wound strand is prevented from slipping as frequently occurs in the use of devices of this general character. Despite this positive gripping action, the manner of fastening the strand in position insures against undue pulling or twisting which would be a source of discomfort to the user.

Devices made in accordance with the structure shown and described may be formed of any suitable material, such as plastic, metal or the like. I have found that a die-cast aluminum construction is particularly desirable because of the light weight of the assembled device and the low cost of manufacture. Preferably, the wire l3 will be steel stock.

What I claim and desire to secure by Letters Patent is:

l. A device of the character described, comprising an elongated body having a shouldered surface at one of its ends, clamping means pivotally attached to said body adjacent the shouldered end for rotation through substantially ninety degrees and normally extending longitudinally of said body in closely overhanging relation thereto so as to thereby hold a coil of hair wound about the body against slippage, and a U-shaped member having legs slidably mounted in socket-forming surfaces of the clamping means for pivotal movement therewith and extending into spaced superposed relation with the body so that the legs of said member will hold other convolutions wound about said coil and said clamping means, and said U-shaped member having a portion engaging the shouldered surface of the body to arrest the pivotal movement of said clamping means when the U-shaped member is in said superposed position.
