BUCKLE.

SPECIFICATION forming part of Letters Patent No. 249,510, dated November 15, 1881.

Application led July 18,1881. (No model.)

To all lwhom it may concern Be it known that we, CHARLES E. DRURY and ALLEN C. VAN CAMP, of Girard, VErie county, Pennsylvania, have invented new and useful Improvements in Harness-Trace Buckles and we do hereby declare that the following is afull, clear,.an d exact description thereof,

reference hein g had to the accompanying drawings and letters or figures of reference marked thereon. I

Our invention` relates to the construction of harness-trace buckles; and it consistsin certain new and useful improvements thereon, as will hereinafter fully appear.

In the accompanying drawings, Figure l is a perspective view of the buckle. Fig. 2 is a horizontal transverse section on the line Fig. l, with the trace and haine-tug shown.

A A, te., are the sides or frame ofthe buckle; A', the back or web of the frame-work B, the presser or clamp; B', a handle for operating the presser. a. a are grooves in the sides A, in which the presser or clamp slides. b is a stop on'the presser, and c care stops on the frame, which prevent the presser leaving the grooves a a'when loosened, so as to allow the tug or i trace to move. `'l is the tug or trace; H, the llame-tug, and s s 's are serrations on the inner slde of the clamp or presser.

Therug or nace is held by this buckle byj pressure, and not by a tongue, as commonly. We do not, however, lay claim to this feature of our device, for it has been done in many forms of buckles.

The frame A and back orweh A' are of one piece of metal, and has the grooves ci a formed therein in any convenient manner-as, for example, hy heilig milled or cut by a milling-machine, or by being formed in the casting when molded. It will he observed from thedrawin gs that the grooves are not parallel with the hack A', but approach it as th ey go hack. The presser B slides freely in the grooves a, and enters them, when pnt in place, from the rear, and is shoved forward far enough to allow the tug 'l t0 be slipped in from the same direction. The lugs b and c prevent the presser from leaving the frame in front when pushed that way to loosen the tug. The knob or handle B' is to facilitate the movement of the presser in loosening the tug. The presser has its face which comes in contact with the tug roughened or serrated, so as to prevent the tug slipping he neath it; but the serrations s s s should not be sharp enough to cut the leather ofthe tug.

The manner in which the tug is clamped is plainly shown in Fig. 2. The more strain there is upon the tug the harder the presser or clamp B is pressed against it on account of the inclination of the grooves c. To loosen the tug the presser is pushed forward by pushing on the knobfB'.

That we claim as new is- In a harness-trace buckle, the frame A, with grooves a. a opening at the rear of the frame, and having stoplugs c c at the front of the frame,in ccmbination with a presser, B, whichslides within said grooves and enters the same from the rear, and is provided with stoplugs b, which engage with the stops c c and prevent the presser from escaping from the grooves, all substantially as and for the purposes mentioned.

In testimony that we claim the foregoing we have hereunto set our hands.
