SLIDE BUCKLE Filed July 16, 1931 Patented Nov. 1, 1932 STATES PATENT OFFCE JOI-IN H. lIDOlVIKIEE, OF WEST I-IAVEN, CONNECTICUT, ASSIGNOR T0 THE WIRE NOVELTY MANUFACTURING COMPANY, 0F WEST HAVEN, CONNECTICUT, A CORPORATION 0F CONNECTICUT SLIDE BUCKLE Application filed July 16, 1931. Serial No. 551,118.

This invention relates to slide buckles employed for adjusting the lengthvof looped straps, webbing or the like, upon which the buckle is mounted, the adjustment being maintained thereby Without any penetration into the material, 'and the objects of the invention are to provide an entirely rigid and indestructible slide buckle; to provide a slide buckle that is-rever'sible; to provide a slide buckle of the aforesaid type made ofmultiple interchangeable units relatively secured in permanent intimate union; and to provide a slide buckle of the aforesaid type including intermediate bars having projec tions extending along the buckle plane. lWith these and other objects in View as may become apparent from the Within disclosures, the invention consists not only of the par* ticular form herein pointed out and illustrated in the drawing, but readily admits of certain modifications within the scope of what hereinafter may be claimed.

This invention is an improvement upon the structure illustrated, set forth and claimed, in a previous application, for a United States patent, executed by. me on July 9, 1931, and about to be filed, on a slide buckle of the pair of loops type, the loops being integrally connected on one side and relatively secured, one to the other, in permanent intimate union, upon the opposite sides of the loops, the slide buckle being there made of a single piece of wire. The improvement about to be disclosed is the association of multiple loop units of such simple construction as will permit the units to be made upon standard wire forming machines and power presses, and united in permanent intimate union.

The character of the improvement may be best understood by reference to one illustrative device embodying the invention and illustrated by the drawing in which the Figure l is an upright elevation of the device; and the Figure 2 is a side elevation thereof; the Figure 3 being an upright elevation of a modification of the device. i

Referring more particularly to the drawing, the buckle units 1 and 2 are each made in substantially rectangular form from separate end 10 of the lower horizontal bar 6 at a Y place adjacent to one side structure. The lower horizontal bar 6 of each unit is provided with formed spaced projections 11 eX- tending along the buckle plane into the loop of the unit, as best illustrated by the Figure l. In associating in a common plane a pair of units, as l and 2, the unit 2 is inverted and preferably turned around so that the lower horizontal bar 6 of the lower unit becomes the upper bar 6 of that unit, and the formed bars 6 of each unit are not only thereby closely associated, but the wire ends 9 and 10 abut, adjacent opposite sides of the pair of units 1 and 2 as thus associated, and as illustrated by the Figure l. While thus associated, the units l and 2 may be secured, one to the other, in any manner prompted by mechanical eX- pediency to thereby provide a slide buckle having a pair of loops 3 and 4 and an intermediate bar structure by means of the formed cooperating bars 6. It is preferable, however, to secure the thus associated units l and 2 by means of uniting the interengaging metal surfaces of the ends 9 and l0 of each unit, and an adjacent engaging portion of thebar 6 of the associated unit, in permanent intimate union as by welding, brazing or soldering, as at l2 and 13 vas designated by the dotted line enclosures in the Figure l, these designations being the convenient places for welding in connection with autov matic production of the device. The associated units l and 2 thus united provide a rigid structure that cannot easily be destroyed; for the securement of the pair of units is so permanent that the original character of the metal surfaces thus united cannot be restored by any force effecting their mere separation. The projections 11 extending along the buckle plane cooperate with the entire flat structure. to provide a reversible slide buckle in that the elevation opposite to that illustrated by the Figure 1 is substantially identical to the .elevation as thus illustrated.

The Figure 3 illustrates a modication of the device which comprises of the upper and lower units 1A and 2A, respectively, each unit is made of substantially rectangular form from separate pieces of Wire andthe units 1A and 2A so associated in a common plane as to provide the pair of loops 3A and eli-k. These units 1A and 2A are preferably made identical, one to the other, each having upper and lower horizontal bars 5A and 6A, respectively, and side structures '7A and 8A, the wire from one side structure being bent inwardly in substantial parallel relation to the upper bar 5A and thus extending a short distance that the wire end 9A may abut 'the wire end 10A of the lower horizontal bar 6A at a place adjacent to one side structure. The difference in the modified form of units 1A and 2A from those of the preferred form resides in the fact that both of the horizontal bars 5A and 6A, extend straight across the plane of each unit and hence across the cominon plane of the associated units. The units 1A. and 2A are relatively associated and secured, one to the other, in a common plane as in the preferred form of the device, the preferred manner of securement being to unite the engaging metal surfaces of the ends 9A and 10A of each unit, and an adjacent engaging portion of the bar 6A of the associated unit, in permanent intimate union as by welding, brazing or soldering as at 12A and 13A, as designated by the dotted line enclosures in the Figure 3, the associated units 1A and 2A being thus rigidly connected and made reversible as in the preferred form of the device.

l claim:

l. A slide buckle comprising a pair of substantially rectangular loops, each loop formed from a separate piece of wire, and each loop having upper and lower horizontal bars and side structures, the Wire ends of each loop abutting, one .end against the other, in one horizontal bar adjacent a side structure, and each of the horizontal bars, having ends of the wire thus abutting, being formed with spaced projections exten-ding into, and within the plane of, its respective loop, the pair of loops being so associated, one with the other in a common plane, that the formed bars cooperate to provide the slide buckle with an intermediate bar having spaced projections extending into both loops along said coinmon plane, and means uniting in permanent intimate union the engaging metal surfaces of both wire ends of each loop and an adj af cent portion of a horizontal bar of the other loop.

2. A slide buckle comprising a pair` of substantially rectangular loops, each loop formed from a separate piece of wire of which the ends abut and secured one to the other, the lower bar of one loop and the upper bar of the other loop being so formed as to provide space-d projections extending within, and along the plane of, its respective loop, said loops being so arranged in a common plane that the formed bars may be united in permanent intimate union by means of Welding, soldering or brazing.

3. A slide buckle comprising a pair of substantially rectangular loops, each loop formed from a separate piece of wire, and each loop having upper and lower horizontal bars and side structures, the wire end of each loop abutting one end against the other in one horizontal bar adjacent a side structure, the pair of loops being so associated, one with the other, in a common plane, that the engaging metal surfaces of both wire ends of each loop and an adjacent portion of a horizontal bar of the other loop may be united in permanent intimate union.
