1 Claim.

This invention relates to an improved slide and is particularly designed to be used on straps which support a button loop or similar device. The object of the invention is to provide a slide which 5 will hold a looped strap against bunching in the centre under excess or oblique pulls.

Another object of the invention is to provide a slide in one piece with a button loop, the ends of the loop having a limited separation under strain, and to provide a cross bar which localizes the separation to the. loop by having cylindrical loops which hold the ends bars of the slide parallel and firm at all points in its sliding path of travel.

The invention is illustrated in the accompanying drawing in which Figure 1 is a face view of .a slide made according to my invention. Figure 2 is a section on line 22 in Figure 1.

The slide is formed with a frame consisting of a top bar and a pair of parallel side bars all lying in the same plane and having a slidable cross bar bridging the frame and supported at its ends on the end bars. The slide illustrated is one made of wire although alternative forms may be used. The wire is shown as including a top bar I and end bars II and I2. The end bars are extended inwardly at the bottom to form the bottom bars I3. The wires are extended further as a support for apparel. I show the wire formed into opposed open looped strands I4 with a restricted part I5 and then divergent to form a loop IS with a bottom piece H. The whole lower structure forms a button loop.

Slidable on the end bars I I and I2 is a flat cross bar 8 which lies in the plane of the slide and its ends are usually bent into loops H! which fit loosely enough to allow free sliding of the cross bar.

The strip 20 is passed through the frame under the cross bar and then back over the cross bar and under the top bar as shown in Figure 2. When the strap is pulled the cross bar I8 is forced intoengagement with the top bar It and the strap is held against slipping.

The top bar is provided with depressed parts which are depressed in a direction parallel with the plane of the slide. This depressing of the parts as shown at 2| provides spaces 22 which receive the strap l9 and allow a slight bulge in the strap at these points. The parts 2| bite more tightly into the strap and form obstructions to any side movement of the strap. The preferred disposition of the depressed or inwardly projecting parts 2| is to place them between the centre and the ends of the top bar.

This holds the central and also the outside edges of the strap in place against riding past the or oblique pull on the parts 2| and any excess strap will not result in any bunching of the strap toward the centre or one edge. canting on the strap.

This also guards the slide against The loops I9 are cylindrical since the cross bar I8 is made of a band of sheet metal and the loops I9 therefore have a substantial length of surface bearing on the end bars II and |2.

This holds the slide part firm and all resiliency necessary in the button loop is confined to the loop. The bar I8 is of sheet metal of material width and lies The cross bar I8 is of relatively thin metal and is narrow, thus having a relatively greater degree of flexibility lateral to the direction of sliding movement than the degree of flexibility parallel to the direction of sliding movement. other words, it is relatively stiff in its movement against the top bar II) but bends under pulling strain on the strap to move, with the strap, to the rear of the depressed parts 2| and firmly hold the parts in place.

This resiliency holds the bar and strap against the depressed parts with the strap between them even when there is no strain on the strap. Iclaim:- A slide comprising a frame having end bars and a top bar, the top bar having inwardly depressed part, a flat narrow cross bar lying no-rmally in the plane of the slide and loosely looped at its ends around the end bars, the cross bar having a resiliency lateral to the direction of movement to permit the cross bar and a strap looped thereon to bend and pass behind the depressed part of the top bar and by this resiliency maintain the strap between the cross bar and the depressed part of the top bar when the tension on the strap is removed.
