SLIDE BUCKLE Filed Feb. 2'7, 1931 o I v uv AT1-y Patented Feb. 23, 1932 UITE STATES raient! "f JOHN H. DOMKEE, or WESTHAVEN, CONNECTICUT, Assis-NCR To THE. WIRE NOVELTYV MANUFACTURING COMPANY, or WEST HAVEN, CONNECTICUT, A CORPORATION F CONNECTICUT SLIDE BTICKLE Application inea February 27, 1931.` serial No. 518,769.

This invention relates to slide buckles employed for adjusting the length of looped straps, webbing, and the like, upon which the buckle is mounted, the adjustment being thereby made and maintained without any penetration oit the buckle parts into the material, and the objects of the invention are to provide a rigid and indestructible slide buckle; to provide a reversible slide buckle of which one upright elevation is identical with the opposite elevation; and to provide a slider buckle of the pair of loops type of which the intermediate bar structure has 3 spaced humps extending in opposite direcf tions out of the plane of the buckle frame.

With these and other objects in view as may become apparent from the within disclosures, the invention consists not only ot the particular form herein pointed out and illus- 2() trated in the drawings, but readily admits of certain modiiications within the scope of what hereinafter may be claimed.

The device about to be described is an improvement upon the structure disclosed in a previous application iilcd by me December 13, 1929, Serial Number 413,863, in which the pair of loops is formed fromv a middle portion of a piece of wire of which the :tree ends cooperate to provide the intermediate bar structure provided with spaced humps eX- tending in opposite directions out ot the plane of the buckle, the pair or' loops having a free side at which the loops, being subject to sep- Y aration both along the buckle plane and in directions perpendicular thereto, are secured one to the other by uniting the engaging metal surfaces in permanent intimateV union, such as by welding wherein the original charof the engaging metal surfaces Vthus in which the Figure l is an upright elevation of the device; the Figure 2 is a cross-section on the dotted lines 2--2; and the Figure 3 is a side elevation of the device.

Referring more particularly to the drawings the device is made of a piece of wire a middle portion of which is bentback upon itself to provide the intermediate bar structure 1 having the looped extremity 2 and the strands 3 and 4 provided throughout their length with the spaced humps 5 and 6, respectively, extending in opposite directions along planes perpendicular to the plane of the buckle frame, the frame being provided by bending the remaining portions of the wire approximately at right angl-es with the intermediate bar structure 1 and in opposite directions to provide the upper and lower side portions 7 and 8, respectively, and each wire portion being again bent into substantially parallel yrelation one with the other and with the general course of the intermediate bar structure 1 to provide the upper and lower horizontal bars 9 and 10, respectively, the Wire ends each being again bent, but toward one another, to together provide the side structure 11 in which the wire extremities 12 and 13 are each bent and directed within the buckle interior, the bent extremities abutting one with the other and the metal surfaces ot both bent extremities 12 and 13iin engagement one with the other, and the loopedextremity 2 in engagement with the bent extremities 12 and 13, being united in permanent intimate union, such as by welding at 1li wherein the original character ot the engaging metal surfaces vthus united cannot be restored by any means effecting a mere separation of the parts 12, 13, and 2. The piece of wire thus formed providing a slide buckle comprising a pair of loops 15 and 16 arranged in a common plane and separated by the intermediate bar structure l, the side structure-11 of the loops 15 and 16 being connected in the manner eX- .El l

plained, but the opposite side of the loops being free and thus liable to be manually forced into separation of the loops 15 and 16 along the plane of the loops or out of such plane. An important feature of novelty of this invention, as combined with other features, resides in so uniting the interfacing metal surfaces at the free side ofthe loops 15 and 16 that they are thereby united in permanent intimate union, such as by Welding at 17 wherein the union is so permanent that the original character of the metal surfaces thus united cannot be restored by any means effecting the mere separation of the loops 15 and 1G. It is to be noted that, While all of the Wire and structural extremities are thus secured to produce a rigid and indestructible device, the Welding process is confined in two places, one upon either side of the slide buckle, as at 14 and 17. It is to be further noted that the slide buckle made as aforesaid is reversible in that its upright elevation With the spaced humps 5 projecting out of the buckle frame, as illustrated by the Figur-e 1, is identical with the reversed elevation (not illustrated) Where the spaced humps 6 project out of the buckle plane in the opposite direction.

I claim 1. A slide buckle comprising a piece of wire bent to form a pair of loops arranged in a common plane and separated by an intermediate bar structure having a looped extremity, said looped extremity being formed by bending a middle portion of the Wire back upon itself, and spaced humps provided by the intermediate bar structure and extending out of said plane.

2. A slide buckle comprising a piece of Wire bent at intervals to form a pair of loops arranged in a common plane and separated by an intermediate bar structure having a looped extremity confined to said plane and formed by bendinga middle portion of the Wire back upon itself, the Wire end portions abutting and bent Within the buckle interior and secured to the looped extremity of the intermediate bar structure, and spaced humps provided by the intermediate bar structure and extending out of said plane.

3. A slide buckle comprising a piece of Wire bent at intervals to form a pair of loops arranged in a common plane and separated by an intermediate bar structure having a looped extremity confined to said plane and formed by bending a middle portion of the Wire back upon itself, the Wire end portions having abutting bent extremities directed Within the buckle interior and engaging the looped extremity of the intermediate bar structure, spaced humps provided by the intermediate bar structure and extending out of said plane, and means uniting the engaging metal surfaces of the looped and Wire extremities in permanent intimate union.

4. A slide buckle comprising a piece of Wire bent at intervals to form a pair of loops arranged in a common plane and separated by an intermediate bar structure having a looped extremity confined to said plane, said looped extremity being formed by bending a portion of the Wire back on itself, the Wire end portions being then bent to provide up per and lower bars and side structures to the pair of loops, the looped extremity of the intermediate bar structure engaging a side structure, spaced humps provided by the intermediate bar structure and extending out of said plane, and means uniting the engaging metal surfaces of the looped extremity and the side structure in permanent intimate union.

5. A slide buckle in the form of a pair of loops arranged in a. common plane and connected at one side and free at the opposite side, the loops comprising a piece of Wire of which a portion is bent back upon itself to provide an intermediate bar structure having a looped extremity and separating the pair of loops formed by bending the remaining Wire end portions at intervals to provide upper and loiver bars and side structures thereof, the looped extremity of the intermediate bar structure engaging a side structure, spaced humps provided by the intermediate bar structure and extending out of said plane, means uniting the engaging metal surfaces of the looped extremity and the side structure in permanent intimate union, and means uniting` the interfacing metal surfaces at the free side of the pair of loops in permanent intimate union.

6. A slide buckle in the form of a pair of loops arranged in a common plane and connected at one side and free at the opposite side, the loops comprising a piece of Wire of Which a middle portion is bent back upon itself to provide an intermediate bar structure having a looped extremity and separating the pair of loops formed by bending at intervals the remaining Wire end portions of which the extremities cooperate to form a side structure to the pair of loops and then being further bent and directed Within the buckle interior into engagement with the looped extremity of the intermediate bar structure, spaced humps provided by the intermediate bar structure and extending out of said plane, means uniting the engaging metal surfaces of the looped extremity and the Wire extremities in permanent intimate union, and means uniting the interfacing metal surfaces at the free side of the pair of loops in permanent intimate union.

7. A slide buckle in the form of a pair of loops arranged in a common plane and connected at one side and free at the opposite side, the loops comprising a piece of Wire of which a portion is bent back upon itself to provide an intermediate bar structure having a looped extremity, the remaining Wire end portions being bent at intervals to provide the separate side portions of the free side of the air of loops, the upper and lower horizontal ars and a side structure for the other side of the pair of loops, spaced humps provided by the intermediatebar structure and extending out of said plane, and means uniting the interfacing metal surfaces at the free side of the pair of loops in permanent intimate union.
