BUCKLE.

SPECIFICATION forming part of Letters Patent No. 250,542, dated December 6, 1881.

Application filed October 28, 1881.

To all whom it may concern Beit known that I, GEORGE M. HUBBARD, of New Haven, in the county of New Haven and Slate of Connecticut, have invented a new Improvement in Buckles; and l do hereby -declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and

1o which said drawings constitute part of this specication, and represent, in-

Figure l, a front view; Fig. 2, a longitudinal section'.

This invention relates to an improvement in that class of harness-buckles adapted for the connection ofthe trace with the tug. and commonly called trace-buckles, and particularly to that class in which the buckle-frame is provided with a stud to enter the perforation in zo the trace, with a loop attached to the tug, and through which the trace passes, the said loop tending to hold the trace on the said stud, the object of the invention being to prevent accidental disengagement of the trace from the z5 stud when the draft on the trace is slackened; and the invention consists in the construction, as hereinafter described, and particularly recited in the claim.

A A represent the upper and lower side of 3o the frame; B, the forward bar; C, the rear bar. The usual loop, D, is made upon the upper side, E upon the lower side, and F on the rear part.

H is a central cross-bar, to which a plate, I, is hinged, this plate extending forward over the forward bar, and at a point substantially over the forward bar a stud, a, projects outward trom the plate, corresponding substantially to the stud, which is usually made fast to the forward bar, butin this case it is a part 4o of the plate and entirely independent ofthe bar.

The usual loop is provided for attachment (No model.)

to the tug, consisting ot' the two sides L L and front bar, P, to which the tug is attached, the said sides curvingoutward ,so as to pass through the frame and bring the rear har, R, outside the trace, as seen in Fig. 2, and in the usual manner.

lThe trace S is introduced inside the rear bar, C, over the hinged plate I, beneath the tugloop bar R, and then set over the stud a on 5o the plate, as seen in Fig. 2. When the draft upon the trace is slackened the bearing of the tug-loop upon the traceis relieved, as indicated in broken lines, Fig. 2, there being then nothing to prevent the trace from moving outward on the stud; hence itfrequently occurs that when the stud is stationary on the frame the trace will slip from its stud and become disengaged. By forming the stud on the hinged plate I, when the draft is slackened the trace 6o naturally th rows outward, as before described, but instead of slipping from the stud, as heretofore, the plate I will turn upon the bar, to which it is hinged, outward and follow the trace, as seen in broken lines Fig. 2, because there will be sudcient friction between the stud and the trace to cause the plate so to follow the trace; hence accidental disengagement is prevented.

I claimo In a trace-buckle, the plate I, hinged to the cross-bar and provided with an outwardlyprojecting stud or tongue, the free end of the plate resting upon the end bar of the frame, combined with a tug-loop having its rear bar, R, arranged to press against the outer side of the trace when held between the bar and hinged plate, substantially as described.
