SLIDE BUCKLE Filed March 17, 1931 JEIHN H DUMKEE Patented Feb. 23, 1932 UNITED STATES PATENT OFFICE JOHN H. DOMKEE, OF WEST HAVEN, CONNECTIGWITT,ASSIGNOR TO THE WIRE NOVELTY MANUFACTURING COMPANY, OF Wlif'l HAVEN, CONNECTICUT, CORPORATION OF CONNECT IGU'I' sLInn BUCKLE Application filed March 17, 1931. Serial No. 523,217.

This invention relates to that class of buckles known as slides and used for adjusting the length of looped straps, webbing and the like, without the penetration of the material by a buckle part.

The invention about to be described is an improvement upon the device disclosed by the Letters Patent Numbered 1588,66 1 and issued to the same applicant January 13, 1931. The device thus disclosed was a slide buckle comprising a rectangular frame having mounted thereon a fixed or sliding intermediate bar split into strands integrally connected at both ends and both of the strands being formed to together provide spaced humps projecting out or the buckle plane in opposite directions. Such a form of intermediate bar was intended to be distinguishable from the intermediate bar structure comprising two bars as disclosed in an earlier patent Numbered 1,762,263 and issued to the same applicant June 10, 1930, the structure there being a pair of loops connected at one side and tree at the opposite side, the intermediate bars integrally extending from the tree side across the buckle to the connected side, the peaked humps of one bar alternating with the peaked humps of the other bar to provide spaced peaked humps projecting out of the plane of the buckle in one direction and also spaced peaked humps projecting out of said plane in the opposite direction. The device herein disclosed however is of the single intermediate bar type but comprises a bifurcated end portion of a piece ofwire of which the slide buckle is made, the end portion of the wire being split into strands integrally connected at one end, the strands being formed out of the buckle plane to provide spaced humps as in the said previous patents, and therefore the objects of the invention are to provide a reversible slide buckle having a single intermediate bar formed with spaced humps projecting in opposite directions at the same spaced intervals andalong planes perpendicular to the plane of the buckle; and to provide a slide buckle of wire structure the wire ends of which are secured to thestructure within the plane of the buckle. With these and other objects in view as may become apparent from the within disclosures, the inventlon consists not only of the particular form 7 herein pointed out and illustrated in the drawings, but readily admits of certain modifications within the scope of what hereinafter may be claimed. The character ofthe invention may behest understood by the reference to one illustrative device embodying the invention and illustrated by the accompanying drawings in which the Figure 1 is an upright elevationof the device; and the Figure 2 is a cross-section upon the dotted line 22 of the previous figure.

The device, as illustrated, is made of wire in a single piece of which an end portion is bifurcated by means of a split longitudinah ly made therein a substantial distance to provide the strands 1 and 2 integrally connected at one end at which end thewire is then bent at substantially right angles to provide the side portion 3, and again bent at substantial- 1y right angles to provide the upper horizontal bar 4 substantially parallel to the strands 1 and 2 of the bifurcated portion, the wire being again bent at substantially right an les to provide the side bar 5 engaged by the rec endsot the strands 1 and 2, the wire being again bent at substantially right angles to provide the lower bar 6 substantially parallel to the upper bar 1, and the wire end being bent at substantially right angles to provide the side portion 7 in substantially longitudinal alignment withthe side portion 3, the wire extremity engaging within the plane of the buckle the bent portion 8 of the wire structure, the bifurcated portionof the wire providing the intermediate bar 9 of the slide buckle. in forming the intermediate bar 9, the strands 1. and flare independently made in undulating form with relatively staggered high points projecting out of the plane of the buckle, each strand being immediately bent, as at 1.0 and 11, in opposite directions out of said plane, and angularly bent and returned, at 12 and 13, relatively crossed, as at 14, angularly rebent and returned, as at 15 and 1G, and recrossed, as at 17, and angularly rebent and returned, as at 18 and 19, andrecrossed, as at20, and so on throughout the length of the strands 1 and 2 thereby providing spaced peaked humps, as for instance at 13 and 19, projecting in one and the same direction out of said plane, and, as at 12 and 18, projecting out of said plane in one and the same direction opposite to that of the humps 13 and 19, as better illustrated by the Figure 2, the engaging metal surfaces of the free ends of the strands 1 and 2 and the side bar 5 being united in permanent intimate union, as by welding, brazing or by soldering as at 21, and the engaging metal surfaces of the wire extremity and the structure at the bend 8 being likewise united in permanent intimate union, so that in neither instance can the original character of the surfaces so united be restored by any means effecting the mere separation of the parts, the slide buckle thus being made rigid and indestructible. The distance of the projections out of the buckle plane in one direction equaling the distance of the projections out of said plane in the opposite direction, the slide buckle is reversible in use in that the buckle may be turned completely around from the position illustrated by the Figure 1 so that the upper bar 4 may be in the position of the lower bar 6, or so that the side bar 5 may assume the position of the opposite side portions 3 and 7. The spaced humps 13, 19 and like humps projecting from the buckle plane in one direction, and the spaced humps 12, 18 and like humps projecting from said plane in the op posite direction, provide an acute detour for a strap threaded into the slide buckle in a manner already known to the art. The humps 15, 16 and like humps, although not projecting out of the buckle plane, are formed like the humps 12, 13, 18 and 19, in planes perpendicular to the buckle plane, as illustrated by the Figure 2.

, I claim:

1. A reversible slide buckle comprising a frame having horizontal upper, lower and intermediate bars and side structures, the intermediate bar being split into strands integrally connected at one end, and peaked humps provided by both strands, the peaked humps of one strand alternating with the peaked humps of the other strand to provide spaced peaked humps extending in one dimotion along planes perpendicular to the plane of the buckle and also spaced peaked humps extending in the opposite direction along said perpendicular planes.

2. A reversible slide buckle comprising a rectangular frame having horizontal upper, lower and intermediate bars and side struc tures, the intermediate bar being split into strands integrally connected at one end, the strands being first bent out of the plane of the buckle, each in opposite directions, and each strand being further bent, relatively crossed and recrossed to together alternately provide spaced peaked humps extending in both repeatedly,

directions along planes perpendicular to the buckle plane.

3. A slide buckle of rectangular form having horizontal upper, lower and intermediate bars and side structures, the intermediate bar being split into strands integrally connected at one end, the strands being angularly bent at intervals, the angular bends of one strand which together provide spaced peaked humps projecting in opposite directions out of the plane of the buckle.
