2 claims. (c1. 132-43) This invention relates to a hair curler of the type which comprises a flexible bar, around the middle portion of which the strand of hair is` wound toproduce the curl, and the end portions of the bar are then bent over the Wound hair to secure the curled strand in place.

tile fabric, as shown in Fig. 6, and severed trans-` These hair curlers, usually consisting of a flat metallic bar covered by a braided textile fabric, have inherent objections in that they possess undue weight and that their bent over ends do not a efficiently grip the wound up hair.

The principal object of the invention is to provide an Vimproved hair curler having reduced weight and enhanced hair gripping efficiency, and that will be furthermore simple, inexpensive,

cross-sectional area l, Fig. 9, of each part 4 has` strong, more durable, conveniently and economically manufacturable, and rendered more conveniently and efficiently utilizable.

Other objects and` advantages will hereinafter appear. v

In the accompanying drawing- Fig. 1 is a plan View showing the indefinite length of flexible bar entering into the making of the hair curler. Y

Fig. 2 is an end elevation of the bar shown in Fig. 1. y

form seen in` Figs. 4, 5. In addition to so compressing and forming thebar l at the interval regions 2," it is coated by a tube 5 of braided texversely at the middle of said regions on parts 4, as indicated by the dash-and-dot lines, into segments ii shown in Figs. 7, 8, each segment thus constituting the completed hair curler. As the a shorter perimeter than that of the atinitial bar i, the braided tubular fabric 5, which is in stretched state upon the main body of the bar,

contracts to the configuration of the regions 2 before severance of the bar, Fig.'6, and to that of the tapered ends 8 of the severed segment 5,-

Fig. 7. Due to said contracting action ofthe braided ends 5a of tube 5 upon the tapered ends 8 of the curler 6, it tends to prevent unraveling of the braiding and prevents the segmental bar therewithin from longitudinal displacement relatively thereto, although adhesive material may be resorted to between bar l and the braiding 5 `for further attainment of these purposes. l

In utilizing the hair'curler, the strand of `hair of the hair, as indicated. Due to the aforesaid.

. :forming and thickening of the end portions 8 Fig. 5 is an end elevation, in an enlarged scale,

of the bar shown in Fig.,3.

Figa-6 is a plan `view of the bar shown in Fig. 3 as it appears after it is covered by a braided textile fabric.

Figs. 7 and 8 are a plan and front elevational View, respectively, of the hair curler constituting the invention. a i a Fig. 9 is an end elevational view of the completed hair curler, in an enlarged scale, shown in Figs. '7. 8.

Fig. l10 is an illustration of the hair curler, as it appears when in operative `condition of gripping the strand of hair in wound up state.

In the making of the hair curler there is `utilized an indefinite length of a flat flexible metallic bar I, Fig. 1, of transverse cross-sectional `configuration shown in Fig. 2, and said bar is toward which tapers the uncompressed parts la of the bar, as seen in Fig. 3. In transverse crosssectional configuration, and in a plane perpendicularly to that of the flatness of the bar4 l, the

ymiddle part 4 is thickened by the said lateral compression thereof, relatively to the thicknes ofthe bar l, thereby attaining the configuration and they are rendered rm and much strengthened, and4 their securing hold upon the hair tuft Ila to maintain it against unwinding is greatly increased, thereby permitting a considerable shortening of the portions requiredfor bending over the hair, and consequently resulting in a lighten.V

. Variations may be resorted to within thescope i of the invention. i

Having thus described my invention, `l. claim;

1. A hair curler having the combination of a flexible flat metallic bar, said` bar having each of its end portions tapered in the plane and contour i of its width and thickened in a plane perpendicularly to said width, and said bar being covered by an envelope. f

2. A hair curler comprising a flexible flat metallicbar, and said bar having each of its end portions narrowed in the plane of its width and thickened in a plane perpendicularly to said width. a
