ALBERT r. van ALSTYN, on NEW YORK, N. Y.

CLASP.

Application filed June 10, 1911.

T0 aZZ'wkomit may concern: 7

Be it known that I, i-LLBERT T. VAN AL- STYN, a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Clasps, of which the following is a specification.

This invention relates to elasps; more particularly to that class of clasps which are used in connection with gartersand the like but which may have a more general application for other similar purposes. The principal object of the invention is to provide a device of this class which shall hold the fabric firmly without danger of injuring the same and which may be positively and securely locked in engagingposition.

F or the attainment of these ends and the accomplishment of other new and useful objet-ts, as will appear, my invention consists in the features of novelty in the construc: tion, combination and arrangement of the several parts generally shown in the accompanyin g drawing and described in the specification but more particularly pointed out in the appended claims.

In the accompanying drawing, Figure 1 is a front view of a preferred embodimentof my invention in open or unengaged posi tion.

Fig. 2 is a sectional view of the same on line 22, Fig. 1.

Fig. 3 is, a view of the buckle in closed position engaging fabric.

Fig. at is a cross sectional view on the line at-l, Fig. 3.

Fig. 5 is a detail perspective view of the apertured member.

Fig, 6 is a detail view of the pivoted plate which is movable in the apertured member.

Fig. 7 is a detail view of the clamping lever.

Fig. 8 is a detail view of the member which is inserted through the apertured member.

The diiiiculty with devices of this class heretofore has been that in binding fabrics of a delicate nature they are easily torn if securely held and if not securely held they slip easily out of engagement with the buckle. This invention is adapted to obviate this difficulty by presenting a large surface for engaging the fabric and a positive means for operating the engaging means and locking the fabric securely in position.

An apertured member 10 is formed of any Specification of Letters Patent.

suitable plain material such as thin metal and the like, the aperture 11 being prefcrably rectangular in form. The edges of the member are folded inwardly and form a guideway 12 at the sides of the aperture. One end of the member 10 is bent to form the loop 13 and a resilient clip 14 which extends below the aperture 11. The other end of the member 10 is bent over at 15 to form a smooth bearing surface and to present a smooth end 16 which does not catch the fabric. Projecting lugs 17 provided with the apertures 18 are bent from the side of the member 10 which is opposite the clip 14:, the opening being adapted to mount the lever 19 by means of its projections 20. A plate 21 having projections 22 at one end is adapted to be pivotally mounted in the guideways 12 and to be movable longitudinally therein. .At the other end of thisplate 21 are projections 23. The lever 19 is provided with perforated lugs 2 f bent from the face of the plate and adapted to receive the projections 23 of the plate 21. It will be seen by reference to Figs. 2 and 3 that the position of the plate 21 is governed by the position of the lever 19. This lever 19 is formed at one end with a bent portion 25 and the tongue thus formed by the bent portion provides a stop adapted to engage the plate 21 when the latter is drawn out of engaging position as shown by Fig. 2.

is. member 26 is formed of a single piece of metal, rubber, or other suitable material and is provided at the ends with openings 27, the portion intermediate of the ends being reduced in width and folded upon itself to form a rounded tip 28 substantially parallel with the ends and separated therefrom by a neck portion 29. r This neck portion 29 is preferably covered with some suitable resilient material 3O such as rubher or the like. The tip 28 is adapted to be inserted through the aperture 11 of the member 10, the ends, however, being substantially the same width as the apertured member so that the member26 is retained on one side of the member 10. When the tip 28 is inserted through the aperture 11 the plate 21 may be moved into engaging position with respect to the tip 28 by the movement of the lever 19. In engaging a fabric A the material is placed over the tip 28 and pressed through the apertured member 10 and the plate 21 is movedinto engaging position against the neck port1on29 of the member 26 thereby engaging the material which surrounds the tip and pressing the material and the tip in engagement with the edge 15 of the apertured member. It will be seen by reference to Fig. 3 that the lcv r 19 is rotated about its axis until the end engages the clip 1% which forces the other end in engagement with the tip 28 thereby protecting the fabric on the tip and assisting in holding the fabric in engagement with the buckle. When the plate 21 and the lever 19 are in engaging position the point of engagement between the lever and the plate falls without the line of on gagement as defined by the end of the plate and the pivotal mounting of the lever so that the plate 2-1 is held positively in engaging position whether the lever 19 is engaged by the resilient clip 1401' not. It is preferable, however, to employ the clip it as shown.

These clasps are commonly located at the end of a flexible band and in such connection' there is provided a double looped link 31, to one bar of which the loop l of the apertured member 10 is secured, which allows the member 10 to swing freely about the bar. The member 28 issupported from the central bar ofthe link by means ofa flexible band 32 which passes through the apertures 27 and assists in securing the ends of the said member together. Tiisflexible connection 32 permits the member 26 to be readily placed in position with respect to the apertured member 10 and to be rapidly and easily withdrawn therefrom. The other bar of the link may be wider than the bar to which the member 10 is secured, as shown by Fig. l to provide a wider surface for the engagement of-a flexible band or fabric While this clasp is particularly adapted for use in connection with garters and the like, his evident that it may have a more general. application and that itis adapted for use in any place where it is desired to clamp a fabric for the reason thatfthe tip 28 provides'a "large surface for the fabric to be engaged and the engaging means is adapted to securely lock the fabric in connection with the clasp.

I desire not to be limited to the exact construction, combination and arrangement of the several parts as herein described, for it is evident that those familiar with the art to which this appertains may make various changes without departing from thespirit and scope of the invention.
