Application filed August 1,

' This invention relates to a clasp for use in securing strands of hair or for other similar purposes. The device maybe used as a tie clasp or as a lingerie clasp to excellent advantage. v

It is the object of myinvcntion to provide a clasp of this type of an improved construction, so designed that it may be easily and economically manufactured and that it will be satisfactory and reliable when in use. Three forms of my invention are shown in the drawings in which Fig. l is a front view of one form of my improved clasp; Fig. 2 is a side elevation thereof with the clasp inverted;

Fig. 3 is a rear elevation thereof; Fig. 4 is a transverse sectional view, taken along the line 44 in Fig. 2;

Figs. 5, 6, 7 and 8 are views similar to Figs. 1 to 4 but showing a second form of my invention, and

Figs. 9 to 12 are also similar views showin a third form.

Fig; 8 is a transverse sectional view taken along the line 8-8 in Fig. 6,and Fig. 12 IS a transverse sectional view taken along the line 12-42 in Fig. 10.

Referring to Figs. 1 'to.4, my improved clasp is formed from a single iece of resilient material, preferably cellu oid, and is bent to a substantially U-shape. The clasp, comprises a face portion 20 and a back portion 21 joined by a curved portion '22 wh ch acts as a resilient hinge. The back portion 21 is provided with an elongatedclosed slot or opening 23-and'the face portion 20 is provided on its rear surface with a raised pro- 1 jection or rib 24.

\Vhen the parts are in their'normalposltion, the rib .24 extends into or through the opening 23, as clearly indicated in F1gs.,2 and 4. It will be noted that the o )ening 23 is substantially larger than the ri 24. a When a strand of hair, or other material, is forced betweenthe face 20 and thebaek 21 of the clasp, a portion of the hair orv other material is forced'into the opening 23. by the rib 24 and is firmly held therein.

-The clas is thus secured in position and is not readlly displaced. All parts of the device are easily construotedand there are no 1 1924. Serial No. 729,644.

In Figs. '5 to 8, I have shown a clasp of somewhat similar construction, having a face 30, a backfil, an opening 32, and a rib 33. In this form of my invention, the opening 32 is made in the face 30 of the clasp and the rib 33 is formed on the bacli 31. When the clasp is made in this manner, a portion of the hair or fabric appears in the center of the face of the clasp when the device is in use.

In Figs. 9 to 12, I have shown a third form of my im )IOVBd clasp which is similar to the second orm shown in' Figs. 5 to 8. The third form of clasp comprises a face 40 and a back 41, said face having an opening 42 and the back having an intermediate portion 43.

width that'it maybe bent upward as indicated in Fig. 11 and will then itself performthe function of a rib, making the provision of an additional rib unnecessary.

In all forms of my invention, the clasp is made from a single unitary and continuous piece of resilient material, such as celluloid, and the opening to receive the rib is entirely surrounded by a substantial frame work of the resilient material which is continuous about the entire circumference of the opening. I

Having-thus described certain forms of myinvention and the advantages thereof, I do not wish to 'be limited to the details herein disclosed, otherwise than as set forth in the claim, but what I claim is A clasp formed of an integral piece of re- .normally to extend substantially centrally there'fnto, said rib gradually decreasing in thickness toward each end of said opening,

and the leg having the rib being wider than said opening.

silientmaterial bent to a substantially U- 'shape,.one leg of the U forming a continuous I Iii testimony whereof I have hereunto aflixed my signature.
