SLIDE BUCKLE Filed June 22, 1931 Patented Dec. 15, 1931 UNITED STATES PATENT OFFICE ROBERT J. HODGE, OF WEST HAVEN, CONNECTICUT, ASSIGNOR TO AMERICAN BUCKLE COMPANY, OF WEST HAVEN, CONNECTICUT, A CORPORATIQN SLIDE BUCKLE Application filed June 22,

My invention relates to an improvement in slide-buckles and particularly to buckles which are especially adapted for use on overalls-suspenders, the object being to produce a slide-buckle of the class described, which shall be of superior resistance to the strains imposed upon it tending to bend and deform its intermediateand upperand lower-bars, especially the former.

In the accompanying drawings:

Fig. 1 is a face view of a slide-buckle constructed in accordance with my invention;

Fig. 2 is a plan view thereof;

Fig. 3 is a sectional view on the line 3-3 of Fig. 1;

Fig. 4 is a sectional view on the line 4-4 of Fig. 1;

Fig. 5 is a sectional view on the line 5-5 of Fig. 1; and

Fig. 6 is a face view of one of the modified forms which my improved buckle may assume.

In carrying out my invention as herein shown, I employ a buckle-frame formed from a single strip of wire bent into rectangular shape to form an upper-bar 10, a lowerbar 11, and complementary end- bars 12 and 13. Preferably, the ends of the wire meet in the middle of the lower-bar 11 and are there united by electric welding at the point 14. The intermediate-bar 15, which may or may not slide upon the end- bars 12 and 13, is formed at its ends with complementary eyes 16 clasping the end-bars, on which they preferably slide up and down. If desired, however, the ends of the intermediate-bar may be fixed to the end-bars so as not to slide thereupon, and it may be undulating in form, as shown, or left straight, as desired.

For the purpose of stiffening the intermediateor slide-bar 15 against the severe downward strains imposed upon it when in use by the buckle-strap, it is swaged so as to produce continuous, central, longitudinal stiffening- ribs 17 and 18 located opposite each other in the plane of the frame, as shown in Fig. 4 of the drawings. These ribs greatly stiffen the bar and prevent it from yielding and bending and so deforming under the severe strains imposed upon it by the 1931. Serial No. 545,996.

suspender-strap. As shown, these ribs 17 and 18 are flanked by corrugations 19, whereby its gripping power is heightened.

Also, for the purpose of stiffening the faces, in addition to corrugating, and so roughening them, as at 22.

As shown in Fig. 1, the upperand lowerbars are flattened in the plane of the frame on both sides of their centers, but in the modified form shown in Fig. 6 the upperbar of the buckle-frame also has its central portion flattened in the manner described, its lower-bar being flattened on opposite sides of its central portion, which is Welded as at 14:.

I claim:

1. In a slide-buckle, the combination with a frame having parallel upperand lowerbars and end-bars, of an intermediate-bar mounted upon the said end-bars and swaged to produce a continuous central longitudinal stiffening-ribs located upon its respective up per and lower faces and flanked upon its edges by corrugations for preventing the strap from slipping, whereby the bar is stifl'- ened against strain in the plane of the buckleframe.

2. In a slide-buckle, the combination with a frame having parallel upperand lowerbars and end-bars, of an intermediate-bar mounted upon the said end-bars and swaged to producea continuous central longitudinal stiffening-rib upon its upper and lower faces, whereby it is stifi'ened against strains in the plane of the frame.

3. In a slide-buckle, the combination with a frame made from a single piece of wire bent to form a rectangular frame having upperand lower-bars and end-bars, of an intermediate-bar mounted upon the end-bars so as to slide thereupon and swaged to produce a continuous central longitudinal stiffening-rib located upon its respective upper and lower faces and flanked along its edges by corrugations, whereby the bar .is stiffened against strains in the plane of the frame and adapted to prevent the strap from slipping.

4. In a slide-buckle, the combination with a frame made from a single piece of Wire bent to form a rectangular frame having upperand lower-bars and end-bars of an intermediate-bar installed between the said end-bars, so asto sllide; thereupomand swaged to produce continuous central longitudinal stiffening-ribs flanked on either side byroughened surfaces.

In testimony w-heneofi; I have signed: this.
