TO ALLiWHOM IT MAY CONCERN:

Be it known that I, R. .I. BAKER, of Madison, in the county of Dane, a-d Statek of Wisconsin, have invented a new and useful improvement in Trace-Buckle; and I do hereby declare that the following is a full, clear, andV exact description thereof, which will venable others skilled in the art to make and Vuse the same, reference being` hadito'the accompanying drawings, forming part of this specification, in which.

Figure I is a top view of my improved truce-buckle, with the trace attached.

Figure 2 is a longitudinal section, taken in the'line gaz, {igl 1.

Similar letters of reference indicatelike parts.

This invention relates to an improvement in trace-buckles, and consists in a double tongue, hung upon or pivoted to a central crank-shaft, which drops the two tongues, at the same time, vertically into two holes in the trace, for holding it fast, and lifts the tongues out of the holes at the saule time to allow the trace to be adjusted or withdrawn from the buckle, as hereinafter described. I

The side pieces c a o f the buckle are connected :tt the bottom of the front end by a cross-bar, b, .to which the tug-strap c, with thetuck-loop al, is attached; and across the bottom, connecting .the sides a a, are also two other bars e e, for bearing the'trace g. when in the buckle, :ind to support the double tongue, as hereinafter" described. llie rear end of the buckle is `connected at the upper side by a'c'r0ssbar, z, under which the trace passes. I i

The double'tongue consists of aJstout bar, k, hung upon a crank-shaft, .1', which is pivoted in projections m m on opposite upper sidesof the buckle. On the lower side of the bar z: are two pins or tongues n n, setat right ongles to it. The holes in the trace are madethesauieidistance apart, so that the tongues n n may enter two adjacent holes at the same time in a vertical or nearly vert-ical position.

When the bar k is raised, the'traceg can slide under the ends ofthe tongues u n. in either direction eiisily,

and when it is lowered the tongues will `enter any two adjacent holes desired, for adjustment, and the bnr c will swing back to lieilat upon the trace, with its rear end set under the rear cross-bar i, to hold it down I mung, while the ends of the tongues project through the lower side of the truce, and bear against the underv cross-bars e e, and divide the strain on the trace so that it will wear better and be less liable to tear and give way under a heavy pull. n

By this arrangement the truce is easily adjusted to any required length, is quickly fastened, and draws perfectly straight- My improved buckle exceeds all others also in' admitting the tongueiwithou't requiring the short or harne-tuigs to be out, whichis a great advantage in strength.

Having thus described my invention, I claim es new, and desire to secure by Letters Patent- The trace-buckle, when constructed and arranged as described, consisting of the curved sides a a, having pivoted at their centres, upon the upper side, by means of the oranlearm z', the ber c, to the under side of which the pins 1t n are secured, said bar k, adjusted to be raised or lowered by means of the crank-.arm, and when placed in the trace, securely held in position by its rear end catching under the bar It, and the pin n against the bars e, as herein shown and described. l y
