IMPROVEMENT IN TRACE-BUCKLES.

Specification forming part of Letters Patent No. 2l `2,203, dated February 11, 1879 application filed May 14, 187s.

To all whom it may concern:

Beit known that I, GEORGE H. DRURY, of Lincoln, in the county of Polk and State of Iowa, have invented an Improved Tracef Buckle, of which the following is a specication: i

The object of my invention is to Vprovide a trace-buckle that is adapted to receive and adjustably connect a haine-tug, a back-strap, and a trace ywithout sewing, and without bending or doubling either one of the iiexible parts of aharness that are designed to be attached directly to the `trace-buckle.

It consists in a rigid frame having an opening at each end, and a bend in its parallel side bars, that brings the openings into two dilferent planes; in a combined loop and plate, having a rigid tongue projecting vertically from a central position to hold the adjustable back-strap; and in a hinged tongue, being iiexibly connected to the frame by means of a swinging carrier, all as hereinafter fully set forth.

Figure 1 of my drawings is a perspective view of my buckle. Fig. 2 is a perspective view of the same, showing a section of a hametug, of a trace, and a back-strap attached.

Together these gurcs illustrate the construction and operation of my complete invention.

a a are the two parallel side bars of my buckle. b b are the ends connecting the bars a. Each end piece, b, is slotted, so as to present an open mouth, through which to pass the end of a haine-tug and the end of a trace. A bend, c, in each of the side bars, a, causes the slots in the ends b to be in different planes, as required, to allow the rear end of a hametug and the front end of a trace to pass each other, and overlap each other within thebuckle. d is a plate, rigidly connected at its four corners with the under edges of the side bars, a, in such a manner that a strap can be passed through the buckle transversely, and between the plate d and its supporting-bars a, in the same manner as a strap is passed through a harness-loop. f is a tongue rigidly fixed to the center of the plate d. It projects from the plate at right angles, andis designed to enter the holes in the center of the adjustable backstrap passed transversely through the buckle. gis a bar rigidly fixed to the top edge of the side bars, a., immediately over the front por-v tion ofthe plate d. In combination with the plate d, it forms aloop, through which the front end of the trace is passed after the back-strap has been secured upon the ton gue f. It holds the trace down upon the back-strap, and thus prevents the back-strap from rising and escaping from the tongue f, upon which it is hooked. 7L 7L are perforated lugs or ears upon the top edges of the side bars, a, that form bearings for a swinging tongue-carrier, m, to which a tongue, a, is hinged. The carrier m is made of flexible and malleable metal, so that it can be readily sprung into its bearings h and secured. It is bowed orv bent into V form, so that when it is folded or turned forward and down it will rest flat upon the trace, and its tongue a will pass through a perforation in the center of the trace, and rest in a horizontal position against the inside edges of the open end, b. `The side bars a, slotted ends b, plate d, having tongue f, loop g, and bea-rings h, may all,l be formed integral with each other in one complete casting, and the carrier m, having the hinged tongue n, attached in anysuitable way.

In the practical operation ot' 1ny'buckle,the back-strap is first fixed upon the rigid tongue f. The haine-tug is next passed through the opening in the front end, and secured by means of set-screws carried in the end b, or in any suitable way. The hame-tug may have a series of perforations in its center, bymeans of which it can be fixed upon the rigid tongue j', and adjusted at pleasure to lengthen and shorten the tug, whenever desired. After the back-strap and hame-tu g are in place, the front en d ot' the trace is passed forward through the opening inthe rear end, I), and under the loop g, to rest straight and at upon the top of the rear end of the llame-tug as far it overlaps the haine-tug. -By turning the swinging tonguecarrier m, and inserting the tongue n in one of the perforations ot' the trace, the trace is readily fastened in the buckle in such a manner that it can be adjusted or removed whenever desired.

I claim as my inventionl. In a trace-buckle, the swinging carrier my,

carrying the hinged tongue n, substantially as and for the purpose set forth.

2. The combination, in a traee-buekle, of the frame having slotted end openings, b b, and the swinging carrier m, having the hinged tongue u, all substantially as and for the purposes set forth.

3. The plate d, having the rigid tongue f, in Combination with the frame having slotted end openings7 and provided with the loop g upon its top7 all substantially as shown and described.

4. The buckle-frame provided with side,y

bars, bent at c, having side openings or slots for the back-straps, and end openings for the hametug and trace, in combination with the plate d and swinging carrier m, provided with the hinged tongue n, all substantially as shown and described.

GEORGE H. DRURY.
