HAIRPIN.

Application led October 6, 1927. Serial No. 224,303.

The invention relates to a new and improved hairpin especially adapted for use in bobbed hair, although it may of course be used for securing hair of any Characteror length.

Bobbed hair in practically all of the present styles is so short that ordinary hairpins are not adequately retained by it and the use of such hairpins is therefore annoying,

ic if not entirely impractical.

My invention consists in a hairpin in the general form of a spiral or convolute, including portions designed to definitely and resiliently grip short or long hair and retain I it in predetermined position, and at the same time retain the pin irmly in engagement with the hair, the device being preferably designed for application by a rotary movement.

Preferably also the device is made in the form of a symmetrical, doubleconvolute and in substantially dished form as later explained in detail. As otherwise described, the device is substantially a double hairpin arranged in spiral or screw form for application by rotary motion, each part of the double pin including closely-spaced resilient portions which grip the hair near the roots, and inner, larger or open portions in which larger bunches of hair are located in such manner that they lie flat or in normal position, these inner portions being also designed to prevent inadvertent reverse movement or displacement of the pin. s., rl"he characteristics and advantages of the invention are further sufficiently explained in connection with the following detail description of the accompanying drawings, which illustrate certain representative embodiments. After considering these examples, skilled persons will understand that many variations may be made without departing from the principles involved, and I contemplate Athe employment of any structures that are properly within the scope of the appended claims. v

Fig. l is a plan view of a hairpin embodying the invention in one form.

Fig. 2 is a side elevation.

Fig. 3 shows one of the pins in use.

Fig. 4 is a side elevation of a modiication.

The hairpin is preferably formed from a single piece of any suitable material, usually yieldable and preferably resilient, such as wire, Celluloid, bone or any other material commonly used for hairpins. When wire or like corrodible material is employed, it is usually coated with a protecting material. In the present specific example the pin consists of a single piece of spring wire bent into the general form of a symmetrical, double spiral or convolute and including a central transverse member l which serves as a handle, the convolutes or spirals 2 extending from opposite ends thereof. The device is preferably of generally dished formation as best shown in Fig. 2; or it may be described as a double conical convolute with each of the portions 2 curving in a generally spiral manner about the center of the handle mem- 'g ber l, and each also being deiected in the same direction away from the plane of said handle member. The end 3 of each member 2 is preferably additionally bent downwardly and slightly outwardly to provide an end or point which will easily enter the hair and then by rotary movement of the pin, grasped by the handle part l, hair is forced into the zones or spaces 4 between the adjacent parts of the two convolutes, with a screw or wedging action whereby the pin is firmly secured in position and correspondingly securely holds the gripped hair in the position intended. While the spacing of the turns may vary considerably, it is usually preferable to arrange the adjacent portions of the two convolutes quite close together, so that when a lock of hair is forced between them -by the wedging action of the flared end portions 3, these adjacent portions of the convolutes will resiliently and tightly grip the hair near the roots. The inward portions of the convolutes in cooperation with the central cross member, provide two enlarged hair-receiving spaces 5 in which, after application of the pin in the manner just stated, relatively large bunches or locks of hair are accommodated, these spaces being of suicient size to permit the hair to lie in a flat or other natural position, while at the same time the closely adjacent portions of the convolutes grip other hairs near the roots, to firmly retain the device in position close to the scalp, so that when properly applied practically no part of the hairpin is exposed or visible excepting possibly the central cross piece or handle portion l. The location of relatively large bunches or locks in the spaces 5 usuall conceals the cross piece l and also serves e fectively to prevent inadvertent reverse r0- tation or other displacement of the pin, since it is evident that any such tendency is resisted by the practical impossibility of the larger bunches'escaping from the spaces 5 through the narrower passages at 6 leading'tothe adjacent portions of the two convolutes.

From the preceding description it will now be understood that the device is, in one sense, a double hairpin, arranged in spiral or screw form, each of such double pins comprising a part of the central member and one of the convolutes, these double pins acting cooperatively'to `firmly retain the hair and to firmly retain 1 the device itself in position in the manner previously described.

Fig. 1 3' suiiiciently explains 4one mode of use. The pin is shown yholding' a front lock in rear-ward position by rst engaging the pin withthe Ifront-lock, moving it back to the desired position and then engaging the pin with portions of the side hair, by 'rotary movement of the pin as suiiiciently-explained above.

Itis obvious that while the'pin is securely retained in position, when desired it may easily be vremovedmanually` by reverse rotation.

Fig. 4 showsa modification in which gripping portions 5 of the spirals or convolutes are-waved or crimped to provide an amplified gripping action.

In eitherliiorm of the device the length of the spirallport-ions v2 may 'evidently bevaried'considerably; that is these portions may belonger or shorter, without materially footing the general structural principle and mode ofl use.

I claim- .1. A hair pin of yieldable material comprising a central portion serving as the sole handle member Vand extending-portions disposed on opposite sides of said central portion, said extending portions being arcuate and substantially parallel to one another but spaced Vfrom one another to provide hair receiving spaces between said extending portions, said extending portions terminating in'free ends lrespectively spaced from one another and Ifrom said substantially parallel portions,saidfextending portions and said free `ends thereofbeing .dished relative to one another.

2. A- hair pin formed of longitudinally extending material, the opposite-portions of whichv are bent arcuately and downwardly andsubstantially parallel to one another but spaced from one-'another to provide hair receiving spaces between said arcuately bent portions, the portionV of sai'dmaterial interconnecting the arcuately bent portions serving as the sole handle portion of the hair pin, said arcuately bent portions being dished rel.- ative to one another and terminating in oppositely disposed vfree ends extending arcuately from opposing locations in the same direction.

3. A hair pin formed oit longitudinally eX- tending material,the opposite portions of which are bent arcuately and downwardly and substantially parallel to one another but spaced from -oneanother to provide hair receiving spaces between said arcuately bent portions, the portion of said materia-l interconnecting the arcuately bent portions being disposed in aplane and serving as the sole handle portion oi the hair pin, said arcuately bent port-ions being dished relative to one another and terminating in oppositely disposed free ends extending arcuately trom opposing locations in the same direction, said free ends flaring' downwardly and outwardly relative to --said arcuately bent portions.

4. A hair pin formed of longitudinally extending material,.the opposite portions of which are bent arcuately and downwardly and substantially parallel to one another but spaced from one another to provide hair receiving spaces between-said arcuately bent portions, said arcuately bent portions being crimped, the portion of said material interconnecting the arcuately bent portion serving as the-sole handle portion of the hair pin, said arcuately bent portions being dished relative to one .another and terminating infree ends extending from opposite locations `ar cuately in the-same direction.

5. A hair pin formed of' longitudinally extending material,1the opposite portions of which arebent arcuately and downwardly andsubstantially parallel to one another but spaced from one another to prov-ide hair receiving spaces between said arcuately bent portitons, said arcuately bent portions being crimped, the portion of saidvmaterial interconnecting the arcuately: bent portion being substantially rectilinear and-serving as the sole handle portions of the hairpin, said arcuately bent portions being dished relative to one another-and terminating in tree ends ext-ending from opposite locations `arcuately in the same direction, said free ends flaring downwardly and outwardly relative to said arcuately bent portions.

In testimony whereof-I have signed this specification this 1st day-ot October, 1927.
