Description

Um. 18, 1955 N. L. SOLOMON J Q HAIR CURLERS Filed Feb. 28, 1952 INVENTOR 26 NATHAN L. SOLOMON ATTORNE United States Patent Oflice 2,720,882 Patented Oct. 18, '1955 HAIR CURLERS Nathan L. Solomon, Englewood, N. J. Application February 28, 1952, Serial No. 273,956 6 Claims. (Cl. 132-40) This invention relates to devices for use in forming curls in the hair. More particularly, the invention deals with a device of the kind defined employing a centrally contracted and grooved elongated member shaped to form a hair end engaging loop or hook and having socket ends and an elongated ring or loop having ball ends for mounting in the end sockets of the member to facilitate free rotation of the member on the ball ends of said loop. Still more particularly, the invention deals with a device of the character described, wherein at least one of the ball ends of the loop is split to facilitate detachable mounting of one end of the loop with the member.

The novel features of the invention will be best understood from the following description, when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed and, in which, the separate parts are designated by suitable reference characters in each of the views and, in which:

Fig. 1 is a side view of a curler device made according to my invention, indicating the positioning of an end of a swatch of hair on the elongated member of the device, preparatory to winding the hair thereon.

Fig. 2 is a view, similar to Fig. 1, diagrammatically illustrating hair wound on the elongated member to form a curl and illustrating the loop of the curler in flexed position.

Fig. 3 is a sectional view of one end portion of the device showing a modified form of construction; and

Fig. 4 is a detailed view of the central portion of a modified form of loop which I employ.

My improved hair curler comprises an elongated bar or member having narrow knurled or otherwise roughened ends 11 and 12. Inwardly of the ends 11 and 12 the member is contracted in the direction of the narrow central portion 13 by what may be termed

conical ends

14 and 15. The

ends

14 and 15 have registering longitudinal grooves or recesses, as at 16, which grooves form, on the surface of the member 10, circumferentially spaced ribs 17. One of the ribs 17 is cut-out, or notched, as seen at 18, and recessed, as seen at 19, to form What may be termed a hook or clip portion 20.

The knurled end portions 11 and 12 have ball sockets of the type and kind illustrated, for example, in Fig. 3 of the drawing and, for purposes of description, the

reference characters

21 and 22, as applied to Fig. 1, will designate the socket ends of the member 10.

Fitting in the

socket ends

21 and 22 are

ball ends

23, 24 of a loop 25. The loop 25 comprises a long bar portion 26 which is normally substantially parallel to the axis of the member 10 and

curved end portions

27 and 28 which join the

ball ends

23, 24 with the bar portion 26 and serve to space the bar portion a predetermined distance with respect to the outer surface of the member 10. It will be understood that the curler device can be constructed of any suitable materials but, from a standpoint of economy, it would be desirable to form the same from plastic material and, particularly, utilizing, in the loop 25, a plastic material having a reasonable so that, in winding .21 swatch of hair, shown in part at 29 in Fig. 1, into a curl, as indicated diagrammatically at 30 in Fig. 2, the curl will flex the bar 26, substantially as shown in Fig. 2, and this flexure will have a tendency to force the

ball ends

23, 24 more firmly into the

socket ends

21 and 22, so as to aid in retaining the curler against displacement from the hair. It will be understood, in this connection, that the curl 30 engaging the bar 26 will definitely position the curler on the curl against accidental displacement.

In the use of the device, after the end of a swatch of hair, as at 29, is placed beneath the hook or clip portion 20, or within the recess 19, fingers of the hand are used on the knurled or roughened ends 11 and 12 to rotate the member 10 on the

ball ends

23, 24. This will result in the formation of the curl 30, as indicated in Fig. 2. When it is desired to detach the curler, the ends of the loop 25 are grasped in a hand and the curler is pulled, in which operation the member 10 rotates, thus unravelling the curl.

In some instances, it may be desirable to detach one end portion of the loop 25 in the operation of winding and unwinding a curl and, to facilitate attachment and detachment of one end of a loop, I have provided a ball end, as at 24' on a loop 25, which has a. transverse split 31 therein, so that the ball end 24 can be sprung into and out of the socket 22 at one end of an elongated member 10, similar to the member 10. In this connection, it will also be understood that the split construction, shown at 31 in Fig. 3, forms spring or yieldable side portions 32 on the ball 24' and this type of construction can be utilized in a device such as shown in Figs. 1 and 2 simply to facilitate an assemblage of the loop on the member. In Figs. 1 and 2, one ball end, for example, the ball end 23, can have a permanent mounting in the socket 21 and the other ball end 24 would be detachable with respect to the socket 22 and the loop 25 would simply be sprung into position. It will also be apparent, however, that

sockets

21 and 22 can be open sockets which will facilitate factory assemblage of the loop 25 by placement of the balls in the sockets and, thereafter, detachment of the loop would. be diflicult.

The free mounting of the member on the ball ends facilitates quick operation in not only the formation of the curl but also the quick detachment of the curler from the hair in the manner previously described.

In Fig. 4 of the drawing, I have indicated at 26 central portion of the bar of a such as shown at 25, 25' and, on the inner surface of the bar 26, that is to say, the surface which would be adjacent to the member which is employed, a plurality of transverse teeth or projections 33 are employed. These teeth or projections would serve several purposes, namely to part and distribute the hair as it is wound on the member, thus tending to spread the hair to form a curl of more uniform external diameter and, further, as the curl engages the bar 26, the teeth will engage the curl to centralize and position the curl on the member, thus preventing shifting longitudinally with respect to the axis of the member and, still further, will materially assist in retaining the curl against unravelling or displacement of the curler from the formed curl.

It will be understood that the longitudinal grooves or recesses 16 provide ventilation for the hair when wound around the member. This will facilitate drying of the hair when it has been dampened to facilitate formation of the curl. It will also be apparent that, with the structure, as shown in Fig. 3 where a detachable end is provided on the loop or bar, which might be termed a bale, the other anchored end is of such structure as to facilitate free swinging of the bar into a position at least at right angles to the member.
