SPECIFICATION forming part of Letters Patent No. 298,508, dated May 13, 1884.

Application flied December J, 1883.

To all whom it may concern: l

Be it known that I, Gnnrsroriinn C. SHELBY, of the city, county, and State of New York, have invented certain new and useful Im- 5 provements in Glasps; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of.

this specification, and to the figures and let- ;Io ters of reference marked thereon.

In said drawings, Figure l represents a perspective view of a clasp constructed in accordance with myinvention applied to a stockingsupporter; Fig. 2, a sectional view of the 1: 5 clasp detached. Figs. 3 and represent modifications thereof; and Figs. 5 and 6 views of a form of clasp now in use, and upon which my invention is an improvement.

Similar letters of reference in the several :zo iigures denote the same parts.

rlhe old form of clasp (shown in Figs. 5 and 6) consists of two pieces of springy metal, A B, secured together at one end, as shown at C, and so fashioned and combined as that the narrowed portion of the part A shall pass through a corresponding opening or slot, b, in the part B, and permit the outer or free ends, c c, to approach each other, and constitute jaws to grip and hold any material interposed 3o between them. To open the jaws of such a clasp as this it is only necessary to press at the point d, and by overcoming the elasticity of the parts A B cause the jaws c c to separate. As clasps of this kind have necessarily to be 3 5 made cheaply in order to be salable, it results that after considerable use the metal loses its springiness, and the jaws of the clasp fail to properly grip the article desired to be held. The form of the clasp, however, has the ad- .to vantage of offering no projecting parts to catch upon the person or clothes of the wearer. My present invention is designed to so improve this clasp as to insure the durability and eer- 'fainty of operation, and still preserve the feature of the absence of projecting parts.

In the embodiment of my invention shown in Figs. 1 and 2 the clasp is made of two parts, D and E,which, instead of being rigidly secured together at one end, as in the old 5o clasp, are jointed or hinged together at f. The

part E, forward of the pivotal point, is provided with an elongated slot or opening, g, and

(No model.)

terminates in a jaw, h, while the part D, forward of the pivot, has a narrow portion, t', which extends through the opening g in the part E, and terminates in a jaw, j, opposite the jaw 7L. The inner end of the part E is provided with points k, adapted to enter the webbing or fabric to which the clasp is to be attached, and with wings Z Z, adapted to be turned 6o down against said webbing or fabric. The rear end of the part D, back of the pivot, is downwardly bent, and normally bears against the part E, thus leaving no projecting part for catching the person or clothing of .the wearer. The elasticity of the parts D and E is not relied upon in my invention to effect a closing of the jaws, as in the old construction df clasp shown in Figs. 5 and 6 5 but I employ a separate spring, G, coiled about the pivot f, and arranged so as by its tension to operate to keep the jaws tightly closed. Thus constructed, my clasp retains all the advantages of the old form of clasp due to the absence of projecting parts, while it enables a cheaper qual- 75 ity of metal to be employed in the construe tion of the parts D and E, inasmuch as the elasticity of these parts is not depended upon.

My improvement is susceptible of various modifications, two of which are illustrated in Figs. 3 and 4. That shown in Fig. 8 differs from that shown in Fig. l only in the respect that instead of the prongs and lugs on the inner end of the part E of the latter figure, the said end is provided with openings or slots o o, for the attachment of the webbing to which the clasp is to be applied.

In the modication shown in Fig. et the parts D and E terminate at their inner ends, opposite each other, and form in themselves other jaws, r s, while the pivot of the part is extended in bail-like form, and constitutes a loop for the attach ment ofthe webbing. Either end of this clasp-that is, either the jaws hj or the jaws 1' s-may be made to grasp the article desired to be held.

My clasp is applicable to a variety of uses; but when used on a stocking-supporter or sleeve-adjuster-such as shown in Fig. l-it will be found especially serviceable, the action of the jaws being always reliable, and the absence of any projecting parts preventing it from catching upon the clothing or injuring the person of the wearer.
