O. L. SHEPHERD, OF UNITED STATES ARMY. Letters Patent Nor 86,874, dated February 9, 1569.

To all whom 'it mg/y concern:

To enable others skilled in the' art to make and usel my invention, will proceed to describe'` its construction and operation.

In the drawings- A A represent pieces of rails coming together at the joint a.

B B are two wrought (rolled) or cast clamps, breaking joint with the rails; also forming a chair at the 'same time; and they can be spiked down toa crosstie if desired, and holes can be madein their-lower outer edges, as in any chair. Where they come `tog'ether underneath, I have a dovetail tenon, or other secure joint, as seen in the-drawings, in black, as also lin red ink. A v

. The upper part of these clamps is suitably punched, as seen by the elongated bolt-hole'b, and correspondingholes are punched in the rail. l

Headed bolts d pass through clamps and rails, having a nut at one end, as seen at d, Figure 2, which is across-section at the joint a.

The rail fits snugly between the clamps, bearing on the base, e, of same, and the top of rail bears also upon the top of the cheeks of clamp.

The elongated slots are intended to provide for contraction or expansion of the metals.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent of the United States, is

A railway-chair, or splice, composed of two .parts in-I terlocked, ,as shown, and bolted above, through the neck of the rail, all as and for the purpose set forth.
