DOUBLE CLASP.

Specification of Letters Patent. Patented J ne 13 1922 Application filed July 1, 1921. Serial No. 481,862.

To aZZ toll-0722, it 'm/ay concern.

Be known that I. lilrino'os L. Minor, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful linprovcments in Double Clasps; and l do hereby declare the following to be full, clear, and exact description of the invention. such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in double clasps.

An object of the invention is to enable both pair of jaws of said double clasp to be simultaneously and symmetrically opened and closed.

The invention comprises two similar crossed members pivoted together between then-ends, and a means to retain the opposing ends of the members in clamping engagement with each other or with an article or with articles disposed between. v

With the above and other objects in view, the invention also consists in the novel features of construction, the combination and arrangement of parts hereinafter more fully set forth, pointed out in the claims and illustrated in the accompanying drawings.

In the drawings in which corresponding parts are indicated by like reference characters throughout the several views:

Fig. l is a front perspective showing a doubleelasp having both pair of jaws open and about to be clamped to a collar;

Fig. 2 is a front el vation illustrating the double clasp secured to a collar, the outline of a bow tie fastened to said clasp being shown in dotted lines;

Fig. 3 is a rear elevation of the double clasp.

Fig. 4 is a rear elevation of one of the two similar members of which the clasp is composed; and

Fig. 5 is a perspective view of a fragment illustrating a slightly modified form.

I have illustrated and described one embodiment of my invention, but it will be understood that the invention defined in the claims may be embodied in other specific forms without departing from the principle thereof. The particular use exemplified is to attach a made-up bow tie to a collar. In the embodiment illustrated, I form the clasp of two members identical in form, each comprisin an elongated strip of metal having an enlarged central portion indicated generally by numeral 1. The said strips of metal may be rigid andunyiel ding or they may be somewhat elastic in order to accommodate different thicknesses of material between the jaws of the opposite clamps. In the description of the construction of these members. it will be necessary to describe only one of them as they are identical in form. The enlarged central portion 1 of each strip or member provided with sparse recesses 2 disposed between its ends. said recesses extending inward from one edge of the strip and forming between them a tongue 3. The ends of the strip are preferably curved in opposite directions so as to diverge from its co-operative member and one of the ends may be provided with a perforation 4 through which a thread may be passed in order to secure the tie to the clasp.

To complete a clasp, two of the described strips or members are assembled by causing a notch of one strip to interengage with a corresponding notch 2 in the other so that said strips are crossed with the unperforated end of one lying behind the perforated end of the companion strip, the two tongues 3 then beingin alincment as shown in Fig. 3, the tongues of the respective strips snowing on opposite sides of the clasp in said figure. Said tonguesfl constitute a pivot which may be surrounded by a coil spring 5, the ends 6 of said coil spring extending in opposite directions and bearing respect ely against one and the other of the strips so as to retain the two strips in elastic clamping engagement with each other or with 'wlmtever may be inserted between the opposiug ends or jaws. To afford room for said coil spring, oppositely extending notches '7 may be formed at the inner ends of the slots 2. Pins 8 may project from each member or strip so that when two of them are assembled the two pins of one strip or member serve as a guiding means to hold the tongue 3 of the co-operating member properly positioned and alined with the other. As a substitute for pins 8, a groove 9 may be formed at the enlarged central portion 11 of each strip ormember to receive the tongue of the opposing members as illustrated in Fig. 5. It will be noted that when the two strips are arranged in operative position as shown in Fig. 3, tongues 3 form a suitable pivot for the two strips, said tongues being held together by spring: Whcn the two strips shown. are fastened together, as illustrated in Figs. 1, 52 and 3, the perforated ends project beyond the non-perforated ends so that the frontof the clasp is longer than the rear.

For the purpose of identifying the several clamping jaws in. describing the oper ation oi? my improved clasp, I have indicated the several clamping jaws or end portions by letters a, 7), c and (Z. Fig. 1 is a view showing the device (detached from a bow for clearness) about to be applied to a collar. The two perforated ends 0 and (Z may be grasped by the thumb and forefinger ot the right and left hands respectively, whereupon the member 0 may be pulled away from the member 7) and the member (5 from the member a so that the said ends or jaws are separated from each other as shown in Fig. 1. Jaws 7) and a are then. inserted beneath. the edges of a collar and the clasp adjusted symmetrically in posi tion. The two members 0 and (Z are then released and return to their normal posi tions under the influence of the spring as shown in Figs. 2 and so that the collar is clasped between the ends of the jaws b and c on the one hand and (Z and a on the other. The said clamping engagement of the clasp with the collar is suflicient to retain the tie in its proper osition as shown in 2; but when it is desired to remove the tie, the tie may be pulled downward easily so to disengage the clamping ends oi the clasp from the collar.

Itwill be apparent from the foregoing that I have provided a simple and inexpensive clasp 0r holder easily manipulated 'for securing; a bow tie to a collar and for other purposes where double clasps are needed. The members being of similar outlines and configuration one set of dies serves to form both members.

I claim:

1. A device of the class described incli1ding a pair of crossed strips of like construction, each having spaced recesses extending transversely from one edge of the strip form- .ing a tongue, one end of each strip being provided with a perforation, said strips being adapted to be disposed in transverse alignment whereby the perforated ends of the strips extend beyond the non-perf0rated ends and the tongues on said strips are disposed inopposed relation, and means carried by the strips for retaining the ends in clampinp; engagement.

2. A device of the class described including two strips of like construction, means whereby said strips are interengaged at their intermediate portions so that the ends of one strip are arranged upon opposite sides of the ends oi the other strip and means for retaining; the ends of said strips in clamping engagement.

A. device of the class described including two. strips of like construction, tongues formed at the intermediate portionso't said strips providing recesses upon opposite sides of the tongues whereby said strips may be interlocked with the ends of one strip disposed upon opposite sides of the ends respectively of the other strip and a coil spring embracing the tongues and having its ends bearing; against opposing ends of the strips to retain the ends of the plates in clamping engagement.

4. A device of the class described including strips of like construction, each having spaced recesses at the intermediate portion forming tongues extending transversely of the strips, said recesses permitting the interlocking of the strips whereby the ends of the strips are arranged in opposed relation and the tongues in a similar position to form a pivot, a coil spring mounted upon the tongues and having each end bearing against one end of each of the strips, each strip being; provided at one end with a perforation, as and for the purpose set forth.

5. A double clasp comprising crossed members pivoted together between their ends and so constructed as to provide a pair of clamping; jaws on each side of the pivot; and a spring exerting its tension to close both pairs of aws.

In testimony whereof I affix my signature.
