To all whom t may concern TRACE-BUCKLE.

SPECIFICATION forming part of Letters Patent NoA 274,849, dated March 27, 1883.

" Application nien December 19, 1ste.l No modem Be it known that I, JAMES THORNTON, of Wellsville,in the county ofAllegany and State ofNew York,haveinventednew and useful Im- VIO provements in Trace-Buckles, of which the following is a specification.

' This invention relates to an improvement in that class of trace-buckles in which the trace is clamped between the bed of the buckle and the tongue-plate pivoted to the .buckle-frame by means of a bail which is attached to the hame-tug, and which bears against' the pivoted tongue-plate. l

The object of my invention is so to construct the buckle that it will permit the easy adjustment of the trace and admit traces of different thicknesses with equal. ease and safety, and that it shall be simple in construction and posi Sess great strength and durability.

My invention consists of the particular improvements in the construction ot' the buckle,

which will be hereinafter fully described, and

pointed out in the claims.

In the accompanying drawings, Figure l is a front view ofthe buckle. Q Fig.2 is an edge 'view thereof. Fig; Sis a longitudinal section,

and Fig. et is a rear elevation, of the buckle. Fig. 5 is an end elevation of thc buckle with the strap and bail removed.

Like letters of'reference refer to like' parts in the several figures. Y

Arepresents the hametug, and B the trace.

C represents the bedl of the buckleframe, provided on both sides with curved bars c c, to which the straps oi' the harness are at- `tached,"and which form loops or openings on of the hame-tuglplays.

e e represent two curved arms which rise from the rear end ofthe bed C, and which are connected by an elevated cross-piece, j'. The arms e e are provided near the cross-piece f with concave depressions or seats g g, and the cross-piece f is provided near its middle with a forwardly-projecting lip, h. 4

I representsthe tongue-plate, and the both sides of the bed C, in whichthe bailD tongue formed on the under side of the same.

J is an oval opening formed in the bed O of the buckle, underneath the tongue t'. The

tongue-plate I is provided at its rear end with two laterally-projecting pivotal lugs, kk, which are seated in the depressions g g ofthe arms e e. The tongue-plate I is also provided ator near the middle of its rear end with a pivotal bar, Z, which is arranged in line with thelugs k 7c, and which engages under the lip h when the lugs k lc restin the bearings gg. In order to attach the tongue-plate to the buckle-frame, it is only necessary to close the lip h down over the bar'l of the tongue-plate, the latter being provided with an opening, m, which permits the application of a propertool to effect the bending ofthe lip h. The tongue-plate I is provided at its front end with a loop, mand the cross-piece f is provided with a loop, o. The tongueplate ismade straight from its pivot to the tongue, and is turned u p slightly at itsftront end beyond the tongue to permit the tongue-plate to be easily taken hold of when the buckle is to bewithdrawn from the trace.

The barscc, formingloops on both sides of the bed C, are provided on their under sidkes, near the rear end of the bed O, with grooves or depressions p p, in which the side bars of the bail D engage, and whereby the bail is guided and held" against lateral displacement. The bail is attached to the hame-tug by means ot' a screw-bolt, q, which connects the rear ends of the side bars with the bail.

Instead of securing the tongue-plate tothe buckle-frame by closing the lip h down over the bar Z of the tongue-plate after annealingthe buckle-frame, the lip It may be cast in the shape of a hook opening downwardly, so as tol permit the tongue-plate to be slipped into place under the lip when its frontend is dropped down upon the bed of the buckle, so that the tongue projects through the hole J in the bed. The ton gue-plate will then be securely attached to the buckleframe when it is in its operative position. The lugs k 7c give the tongue-plate a wide bearing against the buckle-frame, andV enable the tongue-plate to resist the strains to which it is subjected without requiring the plate to be made very heavy. The bail D straddles the bed C ofthe buckle, and is there by permanently attached to the buckle when 2 Y v evase!) the screw-bolt g is in place, while the bail is at the same time permitted all necessary freedom of movement.

I claim as my invention- 1. The combination, in a buckle, of a frame v the side bars, c, whereby the bail is permanently attached to the buckle when the bolt q is in place, substantially/.as set forth.

2. The combination, in a buckle, of a bail, D, a buckle-frame provided with recesses g g,

and a lip, h, and a tongue-plate provided with lugs 7c 7c, seated in the recesses g g, and a bar, l, engaging under the lip h, substantially as set forth.

3. The combination, With a buckle, of a frame provided With a bed, C, having an opening,.J, and side loops, c c, a tongue-plate, I, provided with lugs 7c k, and a bai', l, held respectively in the recesses g g and under the lip h, and a bail, D, attached to the hame-tng-and guided in recesses p p on the under side of the buckle,l substantially as set forth.
