SLIDE BUCKLE Filed sept. 2s, 1931 Patented Jan. 17, 1933 UNITED STATES PATENT OFFICE TOI-IN H. DOMKEE, OF WEST HAVEN, CONNECTICUT, ASSIGNOR TO THE WIRE NOVELTY MANUFACTURING COMPANY, 0F WEST HAVEN, CONNECTICUT, A CORPORATION 0F CONNECTICUT SLIDE BUCKLE Application filed September 2S, 1931. Serial No. 565,321.

This invention relates to slide buckles used for adjusting the length of looped straps, webbing and the like, Without penetrating the material, and, while the invention is adapted to any bent wire form of slide buckle, it is especially adapted to that class of slide buckles made of round wire bent to forni a pair of loops integrally connected at one side and free at the opposite sides and having intermediate bar-structure portions integrally extending from the free sides of the loops to the connected side thereof.

The objects of the invention are to provide a reversible slide buckle having interfacing strap-gripping projections extending` along the plane of the buckle; to provide a slide buckle of the pair of loops type of which the upper, lower and intermediate bar-structures are provided with interfacing strap-gripping projections spaced one from the other and extending along the plane of the buckle; to provide means for securing together the free sides of such a pair of loops; and to provide means for securing the wire ends of the intermediate bar-structure portions to the connected side of the loops. TWith these and other objects in View as may become apparent from the within disclosures, the invention consists not only of the particular form herein pointed out and illustrated in the drawing, but readily adinits of certain inodiiications within the scope of what hereinafter may be claimed.

`While the character of th-e invention is broad in its application to the art, reference is here made to one illustrative device embodying the invention and illustrated by the accompanying drawing in which the Figure 1 is an upright elevation of the device; the Figure 2 is a cross-section upon the line 2 2 of the previous ligure; the Figure 3 is a cross-section on the line 3 3 of the Figure l; and the Figure 4 is a cross-section on the line 4 4 of the Figure l; the Figure 5 being an upright elevation of a modiiied forni of device.

The device about to be described is an improvement upon the devices disclosed by the patents numbered 1,810,647 and 1,762,263 issued to your petitioner June 16, 1931, and

June 10, 1930, respectively, on slide buckles of which'the intermediate bar-structures are provided with angular formations projecting in planes perpendicular to, and out of, the plane of the buckle. Referring more particularly to said drawing, however, the projections as illustrated are formed, not by bending the wire but by pressing spaced portions of the wire to form nubs projecting there,- from. The device is preferably made from a single piece of round Wire of which a middle portion provides the integrally connecting side 1 of a pair of loops 2 and 3 lying in a common plane and formed by bending bot-h wire end portions in substantial parallel relation, one to the other, to provide the upper and lower horizontal bars 4 and 5, respectively, of the pair of loops 2 and 3, both wire end portions again being bent, but inwardly toward one another, to provide the relatively aligned .and free sides 6 and 7 of said loops 2 and 8, and both wire end portions again being bent inwardly and substantially parallel with the upper and lower horizontal bars 4 and 5 to leave the free sides 6 and 7 in substantially relative engagement and to provide the intermediate bar-structure portions 8 and 9 separating the pair of loops 2 and 3, the intermediate bar-structure portions 8 and 9 extending across the buckle and engaging their extremities `10 and 11, respectively, within the plane of the loops, with the connecting bar 1. At some convenient step in the formationof the buckle, as aforesaid, the

spaced nubs 12 are pressed out of the metal of the round wire bars 4 and 5 so that the nubs 12 inwardly project therefrom along the plane of the loops 2 and 3,. and the spaced nubs 13 are pressed out of the metal of the round wire bar-'structure portion 8 so that the nubs 13 project therefrom out of the said plane, and the spaced nubs 14 are pressed out of the metal of the round wire bar-structure portion 9 so that the nubs 14 vproject therefrom out of the said plane in a direction opposite to that of the nubs 13. To prevent ac,- cidental or wanton separation of the relatively engaging free sides -6 and 7 of the loops 2 and 3, the engaging metal surfaces at the free sides 6 and '7 are united, at 15, in permanent int-imate union, as by welding, brazing or soldering, so that the original character of said metal surfaces cannot be restored by any force effecting the mere separation of the loops 2 and 3 at that place, and the engaging metal surfaces of the extremities and 11 and the connecting side bar 1 are likewise united in permanent intimate union. as at 16, within the buckle pla-ne, to provide a rigid structure of the aforesaid orm that is reversible in the sense that the elevation, opposite to that illustrated by the Figure 1, is substantially identical to the elevation as thus illustrated. While the relatively engaging metal surfaces of the loops 2 and 3 at their free sides 6 and 7 and the engaging metal surfaces of the extremities 10 and 11 of the intermediate bar-structure portions 8 and 9 and the connecting side bar 1, are illustrated and described as preferably being united in permanent intimate union, these engaging parts of the device may be relatively secured, if desired, in any less permanent and intimate union. In use, a strap 17 may be threaded into the buckle, as illustrated by the Figure 2, so that the spaced nubs 12, 13 and 14 extend in different directions into the path of the threaded strap 17 to grip the strap 17 from different angles to prevent the slide buckle sliding along a taut strap thus threaded into the buckle.

The modified form of the device, illustrated by the Figure 5, differs slightly in structure from the structure of the preferred form in that the nubs 13 and 14 of the intermediate bar-structure portions 8 and 9 extend along the plane of the loops 2 and 3', but both modified and preferred forms are similar, one to the other, in that they each provide spaced nubs extending in different directions into the path of a strap threaded into the buckle, the modified form having engaging metal surfaces, as at and 16', united in permanent intimate union as in the preferred form.

I claim A slide buckle comprising a piece of wire of uniform diameter throughout its length and bent to form a pair of loops in a common plane, the loops being integrally connected at one side and free, but engaging one with the other, at the opposite sides, intermediate bar-structure portions integrally extending from the free sides to engage their extremities with the connected side, spaced' nubs provided by the intermediate bar-structure portions. each nub being pressed out from said uniform diameter to extend beyond the bar-structure portion of which a full diameter is maintained between, and at the rear of said nubs, the nubs of one portion extending in an opposite direction to those of the other portion and into the path of a strap threaded into the slide buckle, means uniting in permanent intimate union the engagof the loops.
