NATHAN F. MATHEXVSON, OF PROVIDENCE, RHODE ISLAND.

HARNESS-BUCKLE.

SPECIFICATION forming part of Letters Patent No. 586,240, dated July 13, 1897.

Application filed September 14, 1896- Serial No. 605,713. (No model.)

To all whmn it may concern:

Be it known that I, NATHAN F. MATHEW- SON, of the city and county of Providence, in the State of Rhode Island, have invented a certain new and useful Improvement in Harness-Buckles; and I declare the following to be a specification thereof, reference being had to the accompanying drawings.

Figure 1 is a top plan of my invention. Fig. 2 is a view of the same, partly in elevation and partly in section, on line so so of Fig. 1. Fig. 3 is a side elevation of said buckle. Fig. 4 is a top plan view of a strap and box loop with my improved buckle as seen in operation therewith. Fig. 5 is a side elevation of the same.

Like letters indicate like parts.

Myinvention is a buckle particularly adapted for use upon harnesses, though also useful for analogous purposes. It consists of three cross-bars and two side bars,all integral, one of said cross-bars being provided with flanges or shields in combination with a shaft loosely mounted at its ends between said side bars, but in close proximity with the central cross-bar and having a centrally-arranged thumb-piece projecting at one side and a centrally-arranged tongue projecting from the opposite side, the latter being engageable at its end with a socket in the adjacent end cross-bar, as hereinafter particularly described.

In the drawings, AA are the side bars and B O the cross-bars of the buckle, all integral with each other and of the usual construction. The side bars A A are curved or bent, as seen in Figs. 2 and 3, and at the bend have a central cross bar D integral therewith. The central cross-bar D has the two extension pieces or shields E extending therefrom substantially at a right angle with a central space between them, as appears in Fig. 1.

A shaft F is mounted loosely at its ends in the side bars A A and is provided at its center with the tongue G and the thumb-piece H, the latter extending therefrom into or just above the space between the shields or extensions E, as seen in Figs. 1 and 2. The

end of the tongue Gis bent and its tip enters into a central socket in the cross-bar B. (Shown in Fig. 2.)

The strap is shown in Figs. 4 and 5 at M,

or bent out of shape.

one end thereof designated a and the looped end I). The usual holes in the strap are indicated at c.

The cross-bar (J of the buckle is passed through the loop b of the strap M and the other end is carried through the box-loop N and beneath the cross-bar B, as usual, while the strap is fastened by means of the tongue G, passing through one of the holes 0. The pull on the strap M, being in the direction indicated by the arrows in Figs. 4 and 5, draws the tongue G toward the cross-bar B, and the tongue, being bent with its end socketed in the recess in said cross-bar, is able to resist the strain. The lip of said recess or socket prevents the tongue from straightening out or rising above the cross-bar B. The strain upon the shaft F is resisted by the ends of said shaft in their bearings in the side bars A A, as usual; but in order to prevent any bending of said shaft, which might tend to draw the ends out of their seats in the side bars I provide the central cross-bar D as a reinforce and so give great stiffness and strength to the structure, and especially brace the shaft F if it has any tendency to be sprung The extension-pieces E serve as shields to keep the thumb-piece H of said tongue out of contact with the skin of the horse or animal wearing the harness.

To unfasten the strap from the buckle, it is only necessary to push the portion a of the strap M in a direction opposite to that indicated by the arrows in Figs. 4 and 5, whereupon the edge of the engaged hole of the strap M, bearing against the tongue G, moves the tongue from the position shown in solid lines in Figs. 2, 3, and 5 to the position indicated by dotted lines in Fig 3. The tongue is thus cleared from its engagement with the strap and the strap can be slid from beneath the cross-bar B of the buckle; or, instead of pushing the strap, as last mentioned, the tongue G can be operated by the thumb-piece H, which, being seized by the fingers, can be tipped from the position shown in solid lines in Fig. 3 into the position indicated by the dotted lines in said figure, thus rocking the shaft F and swinging the tongue G outof the engaging hole 0 of the strap.

As seen in Fig. 3, the bent end of the tongue G when open, as shown in dotted lines, is

favorably located to enter whichever of the holes 0 of the strap may be chosen, when said hole is brought into position just above said tongue end. It can then be moved into and through the hole by operating the thumb-piece H, or as soon as the strap is engaged by its said hole upon the tongue G the draft or pull on the strap will automatically carry the tongue from the open position shown in said figure in dotted lines into its locking position shown therein in solid lines.

I claim as a novel and useful invention and desire to secure by Letters Patent- 1. The improved buckle herein described, consisting of the curved or bent side bars A A with the cross-bars B O at the ends thereof, respectively, and an intermediate crossbar D, provided with extension-flanges E, having a central interspace, the shaft F, loosely mounted in said side bars and having the bent tongue G and the central thumbpiece H, all arranged substantially as shown.

2. In a buckle, the combination of two bent side bars with a cross-bar at one end and a cross-bar at the other end, which has a recess and a projecting lip over said recess, a shaft loosely mounted in said side bars and having a thumb-piece and a bent tongue, whose end enters said recess and under said lip, substantially as specified.

3. In a buckle, the combination of two bent side bars with a cross-bar at one end and a cross-bar at the other end, which has a recess loosely mounted in said side bars and having a bent tongue, whose end enters said recess and under said lip and an intermediate crossbar, extending from one side bar to the other, parallel and in juxtaposition with said shaft, substantially as set forth.

4. In a buckle, the combination of two bent side bars with a cross-bar at one end and with a cross-bar at the other end, which has a recess and a projecting lip over said recess, a shaft loosely mounted in said side bars and having a thumb-piece and a bent tongue, whose end enters said recess and under said lip and an intermediate cross-bar extending from one side bar to the other, parallel and in juxtaposition with said shaft, substantially as described.

5. In a buckle, the combination of two bent side bars with a cross-bar at one end and with a cross-bar at the other end, which has a recess and a projecting lip over said recess, a shaft loosely mounted in said side bars and having a central thumb-piece and a bent tongue, whose end enters said recess and under said lip and an intermediate cross-bar, extending from one side bar to the other, parallel and in juxtaposition with said shaftand provided with an interspace, wherein said thumb-piece is movable, substantially as described.
