Specification of Letters Patent.

Patented Dec. 21, 1920.

Application filed November 13, 1919. Serial No. 337,765.

To all whom it may concern:

Be it known that we. CHAnLns Sorrows and LOUIS H. Knroknn, citizens of the United States, residing at Monroe, in the parish of Ouachita and State of Louisiana, have invented a new and useful Hairpin, of which the following is a specification.

This invention relates to improvements in hair pins.

An object of the invention is to provide a hair pin which cannot work loose in and will not tear the hair.

Another object is to provide a hair pin which will grip the hair firmly by any one of three separate locking means.

A further object is to provide a hair pin made from a single piece of wire, which is simple, strong, durable and may be economically manufactured.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawing, but may be changed and modified, so lhng as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawing Figure 1 is a plan view of the wire as it appears after the first step in the manufacture of the hair pin.

Fig. 2 is a similar view of the same as it appears after the second step.

F 3 is a similar view showing the third step, with the twist formed intermediate of the ends.

Fig. 4 is a side view showing the completed hair pin.

Fig. 5 is an edge view looking fromthe right side of Fig. 4.

Fig. 6 is an edge view looking from the left side of Fig. 4.

Fig. 7 illustrates a slight modification of the invention.

A single piece of wire 10 is used to form the hair pin constituting the present invention. This wire 10 is first looped intermediate its ends as indicated by 11, the loop 11 being elongated, and having a length when formed substantially equal to one-half of the length of the looped wire whose free ends extend beyond the ends of the loop and form the legs or shanks of the pin. This loop 11 is then bent inwardly intermediate its ends to form the two symmetrical loops 11 and 11 as shown in Fig. 2. A stralght section 12 then divides the two loops from each other. Then the two loops and the wire as a whole are given a plurality of twists 13, where the straight sectlon 12 formerly was. These twists prevent displacement of the loops with respect to the wire. The final step in making the hair pin is to take the free ends of the wire and the loops and bend the same toward each other until the free ends lie nearly parallel and one of the loops. as 11", overrides the other 11*.

The completed hair pin. as seen in Fig. 4, has the shanks or legs of the pin of a length substantially twice that of the length of the loops. The two loops are the same length and are held by the resiliency of the wire in juxtaposition, inclosed by the free ends. The twists 13 lock the loops in place in such a secure fashion that no solder is necessary. However, we desire to use solder in addition to the twists, or even in place of the twists, if that seems desirable. The loops are symmetrical with respect to each other. and each lies inclosed between the two legs or shanks, with one side of the loop in contact with the corresponding free end of the wire, and the other side of the loop crossing or overlapping the corresponding side of the second loop, as indicated at 15. In other words, each loop is made up of a straight side which is substantially parallel with the shank and an inclined side which crosses the inclined side of the other loop, as shown clearly in Fig. 4. The free ends of the loop are each flared or bent outwardly as at 14, so as to lie out of the plane of the wire shanks.

In the modification shown in Fig. 7, the same construction is employed, except that instead of using straight wire throughout as the previous figures disclosed, corrugated wire is used, with the result that each of the loops has a corrugated section 17 and ea ch of the shanks has a corrugated section 16. The corrugations may be otherwise dis posed. We desire to employ corrugations or not as we see fit, and do not wish to be limited to a construction employing either merely straight or merely corrugated wire.

The special feature of this invention which is believed to distinguish it from all other devices of its kind is the provision of three separate locks or locking points by which it is held securely in the hair. ()ne lock is that provided between the two juxtaposed loops, the other two are provided between the sides of either loop and the adjacent leg or shank. By the present construction the user of one of these hair pins has at her disposal for use any one of these locks, or look ing means, that may be desired. The hair pin is held firmly in the hair under all conditions of service and can only be released by separating the loops from each other or from a shank. The out-turned ends of the loop make it easy to insert the hair between the juxtaposed loops. The device being formed of a single piece of wire is adapted for quantity production by automatic ma chinery, and is strong and durable.

hat is claimed is 1. A hairpin made of a single piece of flexible wire bent into an elongated longitudinally extending loop intermediate its ends, said loop in turn having a bend inwardly toward the wire and being secured to the wire intermediate its ends to form two smaller loops, the two loops being in overridin relation.

2. A hair pin consisting'ot' a single piece of flexible wire, said wire being bent intermediate its ends and having a pair of juxtaposed overlapping loops, and shanks or legs inclosing said loops, said hair pin thereby providing three locking means by which it may be held in the hair, one of said locks being formed between said loops, the other locks being formed between each loop and the adjacent shank or leg.

3. A hair pin formed from a single piece of flexible wire, said wire having a pair of symmetrical overlapped loops, and apair of shanks or legs inclosing said loops with the ends of said shanks or legs lying beyond the ends of said loops, said hair pin having three locking means to hold it in the hair, two of said locks being formed by the sides of the loops cooperating with the shanks or legs, the third lock being provided by the two loops.

4. A hair pin, formed from a single piece of flexible wire, said wire having a pair of symmetrical overlapped loops, and a pair of shanks or legs inclosing said loops, said shanks and loops being united by a plurality of twists, with the ends or said shanks lying beyond the ends of said loops.

5. A hair pin formed of a single piece 01 flexible wire, a pair of symmetrical loops formed intermediate the ends of the wire, and means provided at the meeting point of the loops to hold them in fixed relation with the wire, the remaining portion of the wire beyond the loops constituting the legs or shanks of the pin, each of said loops having a straight side in uxtaposition to the shank, and an inclined side, the inclined sides crossing each other between the free ends of the wire, the loops being held in overlapping relation by the resiliency of the wire.

In testimony that we claim the foregoing as our own, we have hereto afiixed our signatures in the presence of two witnesses.
