HAIR CURLER Filed April 25, 1936 INVENTOR.

Harryfif Xiez'zz,

Patented May 24, 1938 UNITED STATES PATENT OFFICE 7 Claims.

This invention relates to hair curlers, and particularly to the type wherein a bar, arm, and band are cooperatingly hinged to allow curling of the hair around the bar and arm, and retain it in curled state.

The principal object of the invention is to pro- Vide a conveniently and economically manufacturable, conveniently utilizable, efiicient, and improved hair curling device of the above type.

Another object is to provide a hair curler of the above type with improved means for positively and efiiciently engaging its hair retaining band to its hair curling bar, for improving the operation and resulting performance'of the hair curler.

Other objects and advantages will hereinafter appear.

In the accompanying drawing,-

Fig. 1 is a side elevation of the hair curler of this invention.

Fig. 2 is a cross-sectional plan view, showing the portion of the hair curler for engaging its hair retaining band to its hair curling bar.

Fig. 3 is a fragmentary plan view showing a modification of the improvements illustrated in Fig. 2.

Fig. 4 is a fragmentary cross-sectional plan view, showing another modification of the improvements.

Fig. 5 is a cross-sectional side elevation of the improvements shown in Fig. 4.

The hair curler I, Fig. 1, comprises a tubular bar 2, a concave arm 3, and a retaining band 4 preferably made of wire. Said bar, arm, and band are hingedly connected to each other as shown at 5, whereby the bar, arm, and band are swingable relatively to each other about a com- `mon axis, as illustrated by the dot and dash lines. The bar 2 and arm 3 are provided with finger-pieces 6, l, and a spring, as shown, bears against said finger pieces, whereby the bar 2 and arm 3 lare normally impelled to bear pressingly against each other as shown, while when the finger-pieces. '6, 'l are pressed toward each other the arm 3 is swung away from the bar 2 to the position shown by the dash and dot lines.

The end portion 8 of the band 4 is formed straight and right angularly to the bar 2, and it carries a device 9 wherewith to engage the band to the arm, as required for the operation of the hair curler. Said device consists of a spherical metallic shell IU mounted over and around the band-portion 8 and having relatively large openings ll that are coaxial with the band portion. The shell l0 is filled with a body l2 of pliable rubber having a bore 13 constituting a bearing to render it revoluble about the band-portion 8 which thus serves as an axle shaft for the entire device 9. On exerting any pressure by rim M upon the equatorial area of the shell Il) it will be shifted eccentrically toward the shaft B, as shown by the dash and dot lines, Fig. 2, due to the compressibility of the rubber body [2 therewithin, while upon release of such pressure the shell IO will at once spring back to the normal coaxial position shown, owing to the resiliency of its rubber body. When the band 4 is swung away from the bar 2 the device 9 is in its normal or coaxial position shown in Fig. 2, but when the band is swung toward the bar the equatorial portion of shell lil strikes the terminal rim |4 of tubular bar 2, which thereupon presses and actuates the shell to a position eccentrically to the shaft 8 and successively causes the shell IU to spring back to normal coaxial state and to fall into and in locking engagement with the terminal of bar 2, as shown in Fig. 1. Swinging of the band 4 out of alignment with the bar 2 will of course produce a reversal of the above described operation and a consequent disengagement of the band from the bar. When utilizing this hair curler, the arm 3 is first disposed to the open inoperative position, shown by the dash and dot lines, Fig. 1, the end of the hair is then placed between it and the bar 2, then said end is gripped by releasing the arm to the spring-pressed position shown against the hair and bar 2, and then the curling of the hair is continued around the closed arm and bar, after which the band 4 is swung into engagement With the bar to maintain the hair in the curled condition as required.

According to the modification shown in Fig. 3, the engaging device Ba; consists of a spiro-helical wire spring 15, the terminals IE of which form a bearing about the band-shaft portion 8 of the band 4, whereby the spring tuft l5, having the general outline ofV a spherical body, is revoluble about the shaft 8 to and around which it is thus mounted. When swinging this band 4 into alignment with the bar 2 and away therefrom it will engage with it and disengage therefrom in the manner described above in connection with the device 9, Figs. 1, 2.

In the modification shown in Figs. 4, 5, the engaging device 9b has a shell lil similar to that Shown in Fig. 2, which shell is filled with a flat metal spiral spring I 1, the inner terminal end IB of which forms a bearing about the bandshaft portion 8 of the band 4 and its outermost hoop I 9 is fiared against the inner Wall of the shell ll), Whereby the latter is revoluble about the shaft 8, and When the band li is swung into cooperative alignment with the bar 2 this device 911 Will engage with it in the above described manner and accordingly disengage therefrom when the band is swung away.

Variations may be resorted to Within the scope of the invention, and portions of the improvements may be used Without others.

Having thus described my invention, I claim:-

l. A hair curler having the combination of a hair winding bar, a hair retaining band having. an end serving as an axle, said band and bar being hinged to each other, a device carried by the said axle including a shell, and a filler of rubber Within said shell being mounted on said axle to permit the shell to move in a motion of translation to a position eccentrically to the axle and successively to a position concentrically with the axle for engaging with and disengaging from the end 'of said bar.

2. A hair curler having the combination of a hair Winding bar, a hair retaining band having an end serving as :in axle, said band and bar being hinged to each other, a device carried by the said axle including a shell, and a filler of elastic material within said shell being mounted on said axle to permit the shell to move in a motion of translation to a position eccentrically to the axle and successiveiy to a position concentrically With the axle for engaging With and disengaging from the end of said bar.

3. A hair curler having the combination of a hair Winding bar, a hair retaining band having an end serving as an axle, said band and bar being hinged to each other, a device carried by the said axle including a shell, and a resilient member Within said shell being mounted on said axle offering resistance to compression upon the periphery of the shell to permit the shell to move in a motion of translation to a position eccentrically to the axle and sucoessively to a position concentrically with theV axle for engaging With and disengaging from the end of said bar.

4.
