SPECIFICATION forming part of Letters Patent l lo. 730,080, dated June 2, 1903. Application fild September 15. 1902. Serial No. 123.486. (No model.)

To all whom it may concern.-

Be it known that I, WILLARD E. BAROUS, a citizen of the United States, residing in the cityand county of Philadelphia,State ofPennsylvania, have invented certain new and useful ImprovementsinxHair-Pins, ofwhich the following is a specification.

The object of my invention is to 'so construet a hair-pin that while it can be readily pushed into the hair will retain a firm hold upon the latter and cannot therefore be readily loosened or dislodged. This object I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which- Figuresl, 2, 3, and 4=aare front elevations" of diiferent forms of hair-pin embodying my invention. Fig. 5 is a side elevation of the hair-pin shown in Fig. 1, and Fig. 6 is a side elevation of the hair-pin shown in Fig. 2.

Referring first to Fig. 1 of the drawings, 1 and 2 represent the opposite legs of ,a hairpin,which are connected at the top'bythebow 3, as usual.

extending inwardly or toward the leg 2, the upper or inner angle 4: of this bend being more abrupt than the lower or outer angle 5, so that while the pin is being thrust into the hair the latter acting upon the gentle angle presented at 5 will readily displace the-legs of the pin, and thus permit the freeentrance of the same into the hair, the abrupt angle 4, however, ofiering much greater resistance to movement of the pin in the opposite direction. Hence the pin once inserted will be firmly retained by thehair, and accidental loosening or dislodgement will be prevented. The abrupt angle 4 further allows easier penetration of the hair within the'legs of the pin and permits easier closing of the pin and locking itself in the-hair. In order to aid in the attainment of the desired result, that portion of the'leg 1 of the pin'between the bend of the same and thebow 3 isflattened, as shown The leg 2 of the hairpin is straight; but the'leg 1 has formedin it a bendthe two legs when the pin is thrust into the hair, the legs resuming their position parallel with each other, however, as soon as pressure is removed from the pin by the hair-passing within the bend,so as to render the retaining function of the bend in the leg. 1 immediately effective.

. ,Iam aware thatithas hitherto been proposed to flatten certain portions ot'hair-pins of the ordinary U-shaped construction; but this was done solely for the purpose of strengthening them against spreading. By providing the flattened portion between the bow of the hair-pin and the hair-retaining bend it will be seen that I attain a new res'ult=not"to'b'e secured by a hair-pin of uniformly-circular section even though it be bent to the same angles as those employed by myself. By fiattening the part of the hair-pin above noted such relatively long springy portion will yield laterally to allow a body of hair to pass the bends and. will .then return to its normal position, where a pin of uniformlycircularsection would be permanentlyspread I at its bow or wouldb'e given a permanent set, since there will be no tendency to yield laterally, as in my improved construction.

If desired, the bow 3 of the pin may also be flattened, as shown in Figs. 2 and 6, and each leg of the pin may have a bend formed therein, as described, the bend ofone leg projecting toward a straight portion of theother leg, as also shown in Fig. 2. i

In some cases it may be advisable to sprea the bow of the pin, as shown at 7 in Fig. 3,

in order to increase the lateral elasticity of ithe.-pin, and in other caseseach leg of the pin 1. A hair-pin having a leg with inwardlybent portion, said leg being flattened transversely between the bend and the bow of the pin so as to impart lateral flexibility to this 5 portion of the pin, substantially as specified.

2. A hair-pin havinga leg with inner bend therein and having both legs flattened transversely between the bend and the bow of the pin so as to increase the lateral flexibility of 1 this portion of the pin, substantially as speci- IO fled.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
