HAIRPIN.

Application filed August 25, 1922. Serial N10. 584,229.

To 'all wlw/nt t may concern.'

Be it known that I, FRANK A. lVIrpAsoN, a citizen of the United States, and a resident of Indianapolis, county of Marion, and State of Indiana, have invented a certain new and useful Hairpin; and T do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like numerals refer to like parts.

This invention relates to a hair pin yprovided with an interlocking portion for preventing it from loosening its position in the hair after being placed therein.

The main object of the invention is to provide a hair pin which will be readily insertable in the hair and manually removable therefrom, but which has an overlapping or interlocking portion which will prevent its falling out or loosening. One of the features of the invention resides in the looped ends of the hair pin, so formed that the overlapping portion will be entirely spaced from the main portion at their adjoining looped end, whereby strands of hair will not catch between them.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims.

In the drawings, Fig. 1 is a front elevation ofl the hair pin. Fig. 2 is a side elevation thereof. Fig. Sis a section taken on the line 3 3 of Fig. 1. Fig. 4; is a section taken on the line 4 4 of Fig. 1.

In the drawings there is shown a hair pin formed of wire, Celluloid, hard rubber or any suitable material, in the usual manner, having a body portion 10 bent near its center so as to provide two Shanks extending substantially parallel to each other and of the same length. As is customary in hair pins of this type, the material is so tempered or formed as to have a spring action, with the bend therein so that it normally takes the shape shown in Fig. 1. This will permit the Shanks to be sprung away from each other while inserting or removing the pin from the hair.

The lower portion of the shank members, near the ends thereof, are split and formed with a straight portion 11 in alignment with said members, the other portions 12 and 13 being drawn out and formed at an angle to each other, as shown in Fig. 1. This formation provides a triangular end portion on the sh ank members, formed by splitting and spreading the saine. vWhereas the base of the triangle formed thereby iscomprised of the portions 11 in alignment with the shank members, the sides 12 and 13 of the triangles extend toward eachother so as to provide the verteXes '111 `which overlap as shown. The normal position'of the pin is such that said verteXes 14 are slightly overlapped and the side port-ions bear against each other under the spring tension of the metal.

When the hair pin is inserted, the verteXes 14 and overlapping portions 12 and 13 are slightly spread or twisted so that hair will pass therebetween toward the bent end of the pin, and after it is in place the spring tension of said pin tends to bring the portions 12 and 13 together so as to lock the hair in the upper portion of the pin. The pin will then be locked in position until such time as sufficient force is applied for withdrawing it to spring said portions away from each other and permit the hair to pass therebetween.

The invention claimed is:

1. A hair pin having a pair of shank members and projections formed near the free ends thereof, said projections being returned portions ofthe Shanks and providing closed ends for the latter, said projections being so arranged as to overlap and adapted to bear against each other under spring tension, when said shank members vare in normal position.

2. A hair pin having a pair of shank members and overlapping ends adapted to bear against each other-for preventing the free passage of the hair therebetween, said ends constituting` returned portions of the Shanks and providing closed ends for the latter, said overlapping ends bearing against eac-h other when the shank members are 1n normal position.

3. A hair pin having a pair of shank members split near the free ends thereofsaid split portions formed to overlap and to bear against each other under the spring tension of said shank members when the latter are in normal position.

4. A hair pin provided with a pair of shank members split near the free ends thereof, one side of the split portions being substantially in alignment with the body of said members, and the inner sides thereof being bent to extend inwardly so as to overllO lap each other, When said shank members are in normal position substantially as shown and described.

5. A hair pin Vhaving a pair or' shank members formed from a single piece of Wire bent near its center, whereby said shank members Will extend substantially parallel to each other, said shank members being 'split near `their freeends, one side of the split portions thereof extending in substantial alignment with the bodyof said members, and the other side of said split portions being drawn inwardly andfbent at an angle to form overlapping vertexes adapted to normally bear against `each other under the spring pressure of the shank members When said shank members are in normal position.

6. A hair pin having a pair of shank members formed of a single piece of Wire bent near its center, said shank members being looped back so as to provide rounded free ends and form inwardly extending portions spaced therefrom, whereby said free ends so formed will be open, the inwardly extending portions being bent inwardly and away from said Shanks so as to overlap each other when the shank members are in normal position, substantially as described.

ln Witness whereof, l have hereunto af- Xed my signature.

FRANK A. WILDASON.
