This invention relates to a slide buckle such as is used on suspenders and the like, particularly for use on shoulder straps of overalls, and has for an object to provide 3 a buckle of-this type in which there are no production of garments. Another object of the inventi n is to provide a buckle which will lie perfectly flat. does not require welding or similar operations and which can be made on anautomatic machine, and therefore, can be made cheaper than some of the two piece "slides now on the market. It 'is still another object of the invention to provide a slide of this character which will have a firmer grip on the strap and therefore will be less likely to slip under strain.

With the foregoing and 0th r objects in 'view. the "invention" consists in certain novel features of construction and arrangements of parts as will more fully disclosed in connection with the accompanying drawings.

eferr ing to the drawings it will be seen that all of the modifications shown are of the same general construction, the modifications showing changes only in the shape of the out-a er side bars of the buckle. Referring to Figs. 1 and 2 it will be seen that the buckle ismade in one piece of wire folded uponitselfat its midlength as shown at 14 and extending side by side to form a portion of; a central bar. The two portions of wire are then extended outwardly in opposite directions .to form end bars 16. and then extend arallel with the central bar 15 and spaced aterally therefrom to form side bars 17.;

5 v They then extend inwardly toward each other to provide end bars 18 and thengside by side as shown at19 to provide a second center ,bar portion in alignment with the central bar portion 15.. The free ends otthe bars 19 are-- connected together and to the centralbar portion by a tubular metal clip 20 which may be a strip of sheet metal-wrapped around the elements as shown. This clip rigidlysecures the ends of the bars 19 togeth= er aswell as the two po rtionsfof the central bar, and makes a veryv rigid construction without the necessity of any welding or similar operations. The wire shown in the drawings is either square or rectangular in cross-section, but obviously could bemade of either circular or other suitable shape. The square or rectangular wire is preferred as the edges give a better grip on the material of the strap so that the buckle is 'lesslikelyto slip under load. The surface of -the wire may be smooth or it may be knurled as indicated by the lining on the drawings. The knurling also increases the ip 011 h apv Referring to Figs. 3 and 4 this buckle is the same as isshown in Figs. 1 and'2, except that the side bars 2i are flattened .at their central portions as indicated at 22. This flattening decreases the width of the two loops formed 100 In Figs. 7, 8 and 9 the buckle is formed thesame as shown in Figs. 1 and 2, then the side bars 17 are humped adjacent their opposite ends as shown at 25 to put a bend in the strap and still further reduce the liability to slip. This bend increases the angle of the strap about the bars as the strap passes through the buckle and therefore, increases the holding effect.

In the form shown in Figs. 10 and 11 the side bars are swedged adjacent their outer edges as indicated at 26 to thus reduce the thickness of the bars and increase their width, but leaving their inner edges 27 of substantially the full thickness of the wire. This makes a bar which is very rigid in both directions and which also has a very firm grip on the strap as the holding edge of the wire remains the full size. This inner edge, and in fact the entire surface of the wire, may be knurled if desired at the time of swedging. This construction improves the appearance of the buckle and gives a stronger frame with a smaller wire than would a mere flattening of the full width of the wire.

In Figs. 12 and 13 the side bars are provided with a series of flattened surfaces 28 leaving a series of notches 9.9 and 30 in its opposite side edges giving a sort of sawtooth effect, which gives a very firm hold on the ma terial of the strap. The flat surfaces may also be left with small projections 31 which engage the surface of the material of the strap and still further increase the holding effect.

These projections or lugs 31 may also be used on the flat surfaces of the forms of Figs. 3 and 5.

It will, of course, be understood that while only the surfaces of the buckle of Figs. 1 and 2 are shown knurled, the surfaces of the other forms may be knurled if desired. These buckles may be formed entirely automatically, and have great strength without the necessity of welding or any other similaroperations. It also will be apparent they have no eyes to rub on a shirt, to cut it, or to give discomfort to the wearer. There is no separate slide on the buckle to interfere with the attaching of the buckle to a suspender, thus making it quicker and easier to handle, and it will work equally well either side up, and therefore, may be applied in this way.

Having thus set forth the nature of my invention, what I claim is:

1. A slide buckle comprising a piece of wire folded upon itself at its midlength to form a portion of a central bar, the two side portions of the wire then extending in opposite directions from said central bar to form end bars and then substantially parallel to the central bar on opposite sides thereof to form the side bars of the buckle, said side bars being swedged to provide a plurality of flat faces separated by notches at the ends of said faces at each edge of the bars and projections between the notches, the sides being then turned inwardly toward each other to form the opposite end bars and then inwardly toward the free end of the first central bar to form another portion in alignment therewith, and means for connecting together the free ends of the two portions of the central bar.

2. A slide buckle comprising a single piece:

portion of a central bar and then extendingoutwardly in opposite directions therefrom and substantially parallel to the central bar to form loops on opposite sides thereof, the free ends of the wire extending inwardly side by side from the opposite end of the buckletoward the free end of the first portion of its central bar to form another portion of the central bar in alignment therewith, and a sleeve extending substantially less than the full length of the central bar and embracing the inner opposed ends of the end portions of the central bar to secure them together and said sleeve being of greater diameter than the central bar whereby to enlarge the central bar intern'lediate its ends and to allow at the ends of the sleeve for the seams of a strap.

3. A slide buckle comprising a piece of substantially rectangular wire folded upon itself at its midlength to form a portion of a central bar, the two side portions of the wire then extending in opposite directions from said central bar to form end bars and then substantially parallel to the central bar on opposite sides thereof to form the side bars of the buckle, said side bars being swedged to decrease their thickness and increase their width, the sides being then turned inwardly toward each other to form the opposite end bars andthen inwardly toward the free end of the first central bar to form another portion in alignment therewith, and a sleeve embracing the opposed. inner ends of the two portions of the central. bar to secure them together.

4. A slide buckle comprising a single piece of wire folded upon itself to form a portion of a central bar and then extending outwardly in opposite directions therefrom and substantially parallel to the central bar to form side bars of the buckle, the central'portions of said side bars, being swedged wherebyito decease their thickness and increase their width, the free ends of the wire, extendin inwardly side by side from the opposite en of the buckle toward the free end of the first portion of the central bar to form another portion of the central bar in alignment there with, and a sleeve extending substantially less than the full lengthof the central bar and the swedged portions of the side bars and embracing the inner opposed ends of the portions of the central bar to secure them to gether.

5. A slide buckle comprising a single piece of a substantially rectangular wire folded upon itself to form a portion of a central bar and then extending outwardly in opposite directions therefrom and substantially parallel to the central bar to form loops on opposite sides thereof, the outer bar of the loop being swedged at its outer edge to reduce the thickness of this edge and increase the width of the bar leaving the inner edge of the bar of substantially its original thickness, the free ends of said bars extending inwardly side by side toward the free end of the central bar portion to provide another portion in alignment therewith.

6. A slide buckle comprising a central bar portion extendinglongitudinally and a pair of rectangular side bars spaced laterally therefrom on opposite sides thereof and connected to the central bar portion at their ends to form loops, said side bars being swedged at their outer edges to reduce the thickness of the outer edge ofthe bar and increase its width leavingthe inner edge of the bar of substantially its full thickness.

7. A slide bucklecomprising a wire forming a central bar and side bars spaced therefrom on opposite sides thereof, and connected to the central bar portion at their ends to form loops, said side bars being swedged at their outer edges toreduce the thickness of the outer edges of the bars and leaving the inner edges of the bars of substantially their full thickness.

In testimony whereof I afiix my signature.
