GERGE A. ROWN, OF KALAMAZO, MICHIGAN. Letters Patent No. 86,501, dated Febmwry 2, 1,869.

mnovnn 311cm,

The Schedule referred -to these Letters Patent and maldng part of the same.

Be it known that l, GEORGE A. BROWN., of Kalamazoo, in the county of Kalamazoo, and State of Michigan, have invented a newand improved Tongueless Buckle for Harness; and I do hereby declare that 'the following is a full and exact description thereof', referencbeing had to the accompanying diawings, andto the etters of reference marked thereon. making a partl of this specification.

This invention relates to certain improvements linmy invention, I will proceed to describe its construction and operation.

I construct my buckle in two separate parts, as shown at C D in accompanying drawing. The first part D,.I make from two strips of metal, semicircular' in shape, connecting them at ends-'with bars the requireddistance apart, asv shown at a a', one

of which is curved, as shown. l

At a point near the centre ofthe part I), Iconstruct a connecting cross-rod, to'which I attach the haines, tug, or strap, as the case may be, as shown at Under the. cross-bar a', on the part D, extending along the length of v its under surface, I make a rib or projection,- P', the purpose of which is to draw down and indent itself into the leather, in the operation of buckling.

I construct the other or second part, 0, of my buckle by connecting two metallic4 plates by cross-bars at the ends, turned or curved at the ends, as shown at d Il.

On the bottom side of the part C, I attach a bedplate, connecting the two strips at b,`.leaving a sufiicient opening in the end fl to vadmit the tug, 'which plate extends along the under surface of the plates,

nearly filling the space between them, toa point at the' other end, leaving a like opening for the tug at d.

This bed-plate by from the place of attachment to the two plates at b', is made just wide enough to fill the space between the plates, and allow' the plates of part D to slip between it and them in the operation ofthe buckle, as hereinafter specified.

At a point near the centre of the second partof the bed-plate b, at P, I construct-a like rib or projection, as at P', extending across the bed-plate b.

This'projection P", placed at an angle from aA point l P P, on each side of the t'ug, iit and firmly hold.

directly under P', has for its object, inthe operation of the buckle, to indent itself into the leather on the j under side of the tug or strap, and acts upon the tug with aclamp= as well as leverage power, holding it seprojections,'as shown ai P P, to draw against Vthe plates of the part D, causing the'projections on the two plates,

as above specified, to press more tightly on the leather.

Both parts of the buckle are made of cast-iron. VWhen the buckle is to be subjected to considerable draught, I construct the tug as shown at gr, by grooving the filling used in making the tug between the leather straps at given distances, as required for takingl up or letting out, which makes a crease in the tug in those places, as shownv at g, and into which the projection In operating my invention, I attach the t'wo parts, by slipping the first part into the second, as above described, over the bed-plate b, back of the projection P..

I then -pass the tug or'strap into the end of the second part, at d', along between the projections P P", under vthe cross-bar at d. audthrough the end of the first part at w, as shown. .The iirst part of the buckle is then pulled down upon the strap or tug, and the projections P P", clamping into the leather, fit into the creases in the tug. The two parts are now securely held in place as adjusted, as above set forth. The tug is lengthened or shortened by simply contracting the length of the buckle by pressing itsparts together, thus relieving the clamp and leveragepower upon the tug, when it may easily be moved to the point desired.

By this construction and arrangement, a strong and desirable buckle is produced. The curved surfaces of the bearing-bars permit the trace to slip easily, when it is desired to make a change, while the ribs firmly clamp the trace when it is in use.

' laving thus fully described my invention,

.Vhat I claim, and desire to secure by Letters Patent ofthe United States, is- The buckles described, consisting of the half, D', having the bar d, with projecting rib P', and half, C, with bed-plate @having the projecting rib P", the remaining beariug-barsbeing provided with curved surfaces, and

the whole being used in connection with a plain orv creased trace, in the manner described, for the purpose set forth.
