BUCKLE Filed July 29, 1932 lNvENToR ATTORNEY Patented `luly 3, 1934 UNTED STATES PATENT OFFICE BUCKLE York Application July 29, 1932, Serial No. 625,567

2 Claims.

This invention relates to a buckle or slide, of the slotted-plate type, for the adjustable attachment of a strap to another strap or to the other endof the same strap; and the object thereof is to provide an efficient, cheap and otherwise satisfactory buckle for fastening together the adjustinent straps of womens underwear and corsets or at the back of a vest and at the waistband of trousers and overalls, and the like.

In buckles of this type the strap will be more securely held against longitudinal displacement, especially where the slots are made fairly wide so that a strap can be easily threaded therethrough, if the middle or intermediate bar is elevated to a plane above that of the main body of the buckle, since it will then effect sharper bends in the strap which is threaded through the slots and over this bar. But in the practical manufacture of these buckles, in dies which stamp out the buckle from the plate or sheet and press up the middle bar by bending it at the ends where it joins the sides of the buckle, the middle bar can be raised to a limited extent only, not sufficient to secure the best results, without fracturing the metal at its upset ends.

The defect above noted has been overcome by my present invention, which consists, briefly stated, in elevating the middle bar of the buckle as much as possible with safety by upsetting its ends and in supplementing the elevation so obtained, to increase the effective height of the bar,

by pressing up in the material of the bar a hollow longitudinal rib or hump.

In the accompanying drawing Fig. 1 is a plan View of my improved buckle; Fig. 2 is a sectional View thereof on the line 2-2 of Fig. 1; and Fig. 3 is a sectional View, similar to Fig. 2, of a slightly modified form of the buckle with a strap attached to its rear bar and another strap threaded through its slots and over the middle bar.

As therein shown, the one-piece buckle, which is stamped from a plate of sheet metal, consists of front and rear transverse bars a and b and a middle or intermediate transverse bar c, which as usual are connected at their ends by side pieces and provide two intermediate slots d and e. The middle bar' is pressed up into a plane slightly elevated above the plane of the main body portion of the buckle, which is substantially flat, with the formation of bends f, f in and a consequent stretching of the metal at its ends. where they join the two side pieces, and a hollow longitudinal rib or hump g is pressed up in the bar, thereby giving it additional eifective height.

In the modification illustrated in Fig. 3 the innei1 end of the front bar a is provided with an integral downturned lip, or teeth h; and there is here shown a strap i which is attached to the rear bar b and a second strap j which is threaded through the slots and over the middle bar.

What I claim as new, and desire to secure by Letters Patent, is-

1. An integral slide buckle which is stamped from a plate of sheet metal and has three transverse bars and two transverse slots, the middle bar thereof being upset at its ends into a plane above that of the other parts of the buckle and further effectively elevated thereabove by an upwardly projecting longitudinal rib upset therein and the slot between the middle and the front end bar being of a width not substantially greater than the total elevation of said middle bar.

2. An integral slide buckle which is stamped from a plate of sheet metal and has three transverse bars and two transverse slots, the middle bar being upset at its ends into a plane above that of the other parts of the buckle and further elevated thereabove by a longitudinal rib upset therein and so confined as to leave flat marginal portions on both sides of said bar and the front end bar having a downturned element at its inner edge and forming with the middle bar. a slot of a width not substantially greater than the total elevation of said middle bar.
