HAIRPIN Fild Jan. 20, 1938 INVENTOR Frazzirbai Z61:

BY P

In)? ATTORNEY Patented June 13, 1939 UNITED STATES PATENT OF -ICE 4 Qla m This invention relates to hair pins in general and particularly to what may be term d safe y hair pins.

One of the objects of my invention 1 p o-- vide simple, inexpensive hairpins which will have the tendency of clamping a substantial portion o f the hair engaged by the pin in a llbst iac fy fiat fashion, and in a direction substan ia ly ad jacent to the head, whereby the hair pin is not only prevented from becoming loose, but whereby the pin is forced into a flat position relatiye to the head.

Another object of this invention is to provide a hair pin made of a wire structure, preferably of round or circular cross section, and which structure consists of four distinct parts i. e. a highly resilient, relatively short or small loop at one end of the structure, two parallel-pairs of "leg portions, of which in one pair the legs are adjacent to each other, whereas in the other pair the leg portions are spaced from one another, and finally an angular connection between the two parallel leg portions, which connection is very gradually "tapered so as to ease the hair to beheld by :the pin gradually into ,a fiat position and without bunching it.

:Another object of this invention is to so dimension the two parallel leg portions that they substantially equal in length, for the purpose of accommodating approximately equal parts of hair, so that the twisting motion exerted by one part of the hair, held between one pair of the leg portions, will be counteracted by the hair held between the other parallel leg portions, thereby 7, assuring the pins laying substantially ilat against the head.

Another important object of this invention is to bodily curve the wire structure of the pinso as to approximate the curvature of the head.

: The foregoing and still further important objects and advantages of my invention will become more fully apparent from the ensuing description and the accompanying drawing, which latter, al-

though illustrating specific forms, is by no means 5 intended to limit me to the actual showing, and

in which Fig. 1 illustrates one of my pin constructions.

Fig. 2 illustrates another form of my pin construction.

:50 Fig. 3 is a side elevation of Fig. 2.

Figs. 4 and 5 illustrate modified forms of my pin construction.

Fig. 6 is a plan view, and Fig. 7 is a side View of another embodiment of my pin construction with flattened adjacent parallel leg portions, and

Fig. 8 is a modified form of Fig.6.

Referring now specifically, to the drawin from Fig. 1 it will be clearly seen that the structure ,of my hair pin consists of the relatively small ,and narrow resilient loop I 0, from which extend, in 1:5 closely adjacent parallel relation, leg portions H and I I, which are extended into spaced parallel leg portions I2 and I2 by Way of gradually die verging connections I3.

The hair engaged by the pin is indicatedjby 10 parallel lines.

' It will be seen that the adjacent leg portions of the pin engage the hair so that hair portion H passes over leg portion I I, and under leg portion I!" up to about the middle of diverging leg,;con- 3135 nection I3, whereas the other, directly opposite half of thehair portions H, passes under adjacent leg portion I I. Engaged by leg portions 'I-2 and I2, the hair strands pass in oppositedirection, that is to say, hair portion HI passes under'leg-portion I2, while hair portion H2 passes over leg portion I2. In this way the twisting motion imparted to the pin by hair portion H in downward direction, will be counteracted by hair portion tending to twist the pin in upward direction. The same applies to hair portions H and H2, since hair portion H tends to lift leg portion It, whereas hairportion I52 tends to bear down against ;leg portion I2. Ihese oppositely acting forces result in the pin remaining flat against the head. 4

In inserting the .pin into the hair, it is advan tageous to first run either of the spaced 1egpo1 tions I 2 or l2) under the hair, while lifting the other leg portion above the hair, and when suflicient hair is passed in between lo Portions I I and II the position of leg .(I2"or -I2 is reversed, whereby the hair is held in the'manner shown in 'Fig. l.

In order to accommodate the hair pin more 0 readily in respect to the head, the pin structure is preferably curved, as indicated in Figs. 3 and 7, which curvature approximates that of the head.

It is to be observed that the distance between the two spaced leg portions I2 and I2 approximately equals the width or breadth of loop II].

In Figs. 2 and 3 is shown a similar structure to that illustrated in Fig. 1, wherein the two adjacent parallel leg portions I 4 and I4 are superimposed above one another, and loop I0 is twisted at I5. A similar twist of the wire structure will be seen at I6, Where leg portions I4 and I4 commence to diverge. The operation of this device is very similar to that explained in connectlon with Fig. 1.

In Figs. 4 and 5 I have illustrated still another 7 modified form of my hair pin where the adjacent parallel leg portions [1 and I1 and I8 and I8, respectively, are in a horizontal plane next to one another and in substantially the same plane as spaced leg portions l9 and I9 and 20 and 20',

respectively. The wire parts between the loops the leg portion 11, whereas in Fig. 5 the left-hand adjacent leg portion I8 passes over right-hand leg portion 18'. I prefer constructing the modified forms shown in Figs. 4 and 5 in the way illustrated inFig. 5 'for right-handed persons, where-- as the arrangement shown in Fig. 4 is intended for left-handed persons.

Referring now to Figs.'6, 7 and 8, in these figures are illustrated hair pins similar to those shown in Figs. 4 and 5, with the variation that the adjacent leg portions 26 and 21, 28 and 29 are 8, it will be again seen that in Fig. 6 the portion 21 overlaps portion 26, whereas in Fig. 8 the portion 29 overlaps portion 28.

The loops in all of the structures shown are relatively small and narrow; as material for the hair pin I prefer employing round stock, which I first anneal, bend, twist and flatten as the case may be, whereupon I harden the material by wellknown processes so that the loop becomes highly resilient and prevents the pin from changing its intended shape. From Figs. 3 and '7 it will be clearly seen that I also prefer to curve my hair pin for accommodating the curvature of the head. 1

to make such changes and improvements in my invention, without departing from its broad scope, as expressed in the annexed claims.

I claim:

1. In a hair pin, a wire structure comprising a relatively short, small, resilient loop, a pair of closely adjacent, superimposed parallel leg portions extending from the loop and intended for holding flatly a portion of hair engaged by the pin, another pair of parallel, but spaced leg portions forming continuations of the superimposed leg portions; angular, very gradually inclined connections joining the two pairs of leg portions, the distance between the spaced leg portions substantially corresponding to the width or breadth of said loop, said superimposed and said spaced parallel leg portions being substantially of equal length.

2. In a hair pin, as set forth in claim 1, said closely adjacent, superimposed leg portions overlapping one another.

3. In a hair pin, as set forth in claim 1, and wherein the wire material of the pin is of originally circular cross section, said closely adjacent, superimposed leg portions being flattened and overlap one another.

4. In a hair pin, as set forth in claim 1, and wherein the body of the structure is curved to approximate the curvature of the head.
