maximum number of improved features and advantages which make the pin more useful than previous pins.

in the hair, which has a spring action so that it will grasp the long hairs firmly, which can be readily inserted into the hair without the necessity of spreading the legs widely apart as in ordinary bobby pins so that the pin can be easily placed in thedesired position by pushing it lengthwise into place without the need for any substantial separation of the legs, which is invisible to a large extent when it has been placed in the hair so that it does not detract from the appearance of the coiffure, which has ends formed or shaped in such I a way that they will readily pass into the body of hair, which is made of such aclass of material that it can be cheaply manufactured, I

and which can be readily roduced by the use of suitable machines rom the material selected for its manufacture.

To these and other ends the invention consists in the novel features and combinations of parts to be hereinafter described and claimed: I

In the accompanying drawing: Fig.1 is a side elevation on a considerably enlargedscale of a hairpin embodying my improvements; 1

Fig. 2 is a view similar to Fig. 1' showing the pm as it appears when the legs are grasped away from f these recesses or openingsbein adapted'to receive and retain, hair and 't e. shape of the pin being such as to resist displacement at their extremities and pulled each other;

Fig. 3 is an edge View of. the pin shown in Figs. 1 and 2;

Figs. 4 .and

5 "are sections, respectively,

on line 4 4 and line 5.5 of Fig. 1; and

Fig. 6 is an end view of the pin looking .to-- ward thefold or butt end.

As shown in the drawing, the improved pin of my invention is for the most part symmetrical in form by reason of the" fact that parts on one side'of a longitudinal center linehave corresponding parts located on the opposite side of such line. To an extent, however, the pin is asymmetrical, because the free end portion of one leg is somewhat shorter than the free end portion of theop posite leg, whichrmakesone of the legs of the pin somewhat longer than the other. The

' .pin is constructed of relatively inexpensive round wire, but in certain portions of its structure this wire is shaped to form flattened web-like portions.

' In the drawing, the short leg of the pin is indicated by reference character 10 and the long leg. by reference character 11. Short.

leglO has a short end portion 12 formed. 551 111181 but longer flattened nd portion 13. The extremities of these en portions are rounded, as shown at 14 in Fi 3, so that they can readily penetrate the air without catching therein. The end portions 12 and 13 are divergent, as shown in Fig: 1, and normally occupy the position shown in that View by reason of the springiness of the legs. Back of the end portions 12 and 13 the legs are bent to form zigzag portions (these portions being of roundcross-section) whichpresent a number of projections that are in reglstry with each other. .The projections on leg 10 are indicated at 10 in Fig. 2, and the projections on leg 11 are indicated .at

flatteningthe wire, and! leg 11 has a a Q in the hair when the pin has been once positioned. In the rear of the. recess or opening 19 the legs 10, 11 are rovided with similar oppositely located we portions or flats 20,

. ning able part of their length at the rear of the down the leg portions through a noticeortions and in that portion corrugated le g described generall of the pin whic mafy be as the looped or olde tions 20, 21 the cross-section of the pin is round or substantially round, as shown at 22, and preferably this ortion 22-;of round cross-section is extended not onl over the extreme butt end of the pin, but to some degree in advance of this extreme butt end, so that while in the portions 20, 21 the body of the pin is widened through, say, a little more than half the distance from the corrugated portion to the extreme inner .end of the pin, the narrow rounded portion is located (118 someartly in the longitudinall p y .back

what convergent loop'portlons ocated ofthe' corrugated portions.

By providing the. flattened portions 20 and 21 or their eggmvalents at the rear of the corrugated shan portions of the pin, the'article is given considerable springiness and has an efie'ctive clamping action on the hair so that the corrugated portions are firmly pressed against the hair from opposite sides by the spring in those portions of the legs whichare disposed toward the'butt. The flat portions 20, 21 are very effective in imparting as ring clampm an the leg action to the leg portions, portions are so formed as e fectively tb resist longitudinal dislocation in the hair. The sprin I pin is well illustrated in Fig. 2, which showscharacteristic of the the positions taken by the-legs when the free extremities thereof are grasped. and 'se rated. It will be observed that when 's is done the separation of the legs is strongl resisted b the spring portions 20, 21, W11! areonly s 'ghtly displaced (separated) from the osition shown in Fig. 1. Upon release of t e legs when inthe position shown in 2, they return to the position shown in. Fig. 1 and this will occur when the legs are separated an indefinite number of times, owin to the inherent resiliency of the pin iwhich wi l persist during long periods of use.

The improved pin serves very satisfactorily for use in coifl'ures of long hair because owing to the formation and disposition of the end ortions 12, 13, the pin can be. v ery readily inserted into thefhai'r withoutga substantial amount of separation'jofthelegs bein necessary. The pin will-be'securely held in the.

hair owing to the 'clampi-ngaction which 7 is provided asjabove'described, and owing to thefformation of the leg p01'tions -As the corrugated leg portions areof' round crosssectlon'an'd attenuated, they are to Y a large degreeii-ijiivisibleiwhen the pin isin posit on'in thefcniiiure, and this, of course, isfvery desirable. The butt end portion of the pin is ,also' 'constructed of material hav-' mg'a round cross-section and this portion (1 portion thereon However, in the rear of the flattened por-- stan'tial portion of their length, and

of the in is likewise-substantially invisible when t e pin is in position in the hair. Thus the amount of metal which is disclosed to" view when the hair has been'dressed is reduced to a minimum. 7 The pin can be produced from round stock which is comparatively inexpensive and can be readily made iii quantity by hairpin machines which are not unduly complicated in their construction.

' Various changes can-be made in the details of the structure as herein described without departing from the scope of my invention as defined in the claims.
