IMPROVEMENT IN BRIDGES.
Specification forming part of Letters Patent No. 146,397, dated January 13, 1874 application filed September 13, 1873. i
'To all whom it may concern:
Beit known that I, RICHARD LONG, of Stelapolis, in the county of Iowa and State of Iowa, have invented a new and Improved Y Bridge, of which. the following is a specication: In the accompanying drawing, Figure 1 represents a side elevation, and Fig. 2 a cross-section, of my improved bridge on the line G C,
rig. 1.
used, according to the width of the bridge.
The ends ot' the arch rest in cast-iron shoes, B, on abutments O, and are rigidly connected by a strong stay-rod, Gr, which extends chordlike in longitudinal direction, passing above the cross-beams E. The rod G takes up the outward strain of the arch, and allows the sill to be dispensed with, which is desirable, as it requires splicing, and rots out too quickly. The cross-beams E are supported by a number of stirrups, F, which are made of round iron, suspended from the top of arch A by nuts and washers. The legs of the stirrups F,
prevent any weakening of the rod. The lower side of the cross-beams Eis correspondingly grooved, and provided with similarlygrooved washer -plates E. The sleepers, planking, &c., are placed in the usual manneron the cross beams E, which are also diagonally braced, to increase the strength of the bridge. The railing H is attached to the stirrup-rods by staples, in a very simple manner.
The bridge may be used for railroad or con1- mon purposes, only that in the former cases a greater number of stirrups and cross-beams is required.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination of arches A, having end shoes B and connecting stay-rods G, with cross-beams E, washers E', and strrups F, arranged symmetrically with the centralaxes of the arch, and forming an improved bridge for railroad and other purposes, substantially as set forth.
RICHARD LONG.
