f- The fish-plates o1'- clamps B B may be made in sections, and are, in the full sized bridge, made hall' oval, and of such size that, when the barsare spliced to the T-rail A, the iron will be twice as thick, and bolted by a suitable number of bolts, C C. y The base ofthe T-rail A to be somewhat wider and thicker than common railroad iron, so that the loops, clevises, or stirrups, D D, may pass through or be clamped up to it,
as shown bythe notches a a. The loops or stirrups D D are to be put on about'every jive feet, and, to prevent them from slipping down from their places on the arch, a bolt, C, is passed through just above each notch al, and at its side.
The chords E, to be ina-de of rods, or bars, or links, or wire-cables, the loops D D being placedloosely around, or may grasp the same firmly. The chords are secured at the ends by suitable nuts and jam-nuts, b, or keys passing outside at v,the ends of the shoes G G Having thus fully described my invention,
lVhat I claim as new, and desire to secure by Letters Patent, is
