RAILWAY-JOINT.

SPECIFICATION forming part of Letters Patent No. 478,983, dated July 19, 1892.

Application filed November 30, 1889. Serial No. 332,124. (No model.)

To all whom it may concern.-

Be it known that I, FREDERICK W. BOND, a citizen of the United States,residing at Springfield, in the county of Greene and State of Missouri, have invented certain new and useful Improvements in Railway-Joints; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to railways, and particularly to rail-joints.

In railway-chairs as heretofore ordinarily constructed great danger, expense, and inconvenience have been caused by the sagging of the rails at their ends by the passage of wheels of locomotives and cars over them. It has frequently been attempted to remedy this by adopting a heavier rail and also by the use of new and cumbersome forms of railfastenin gs, the employment of which in nearly every case involving the abandonment of the fish-plates and angle-bars now in general use for maintaining the proper position of rails in relation to each other when joined, and which incur so great an expense as to render their use unprofitable.

The object of the present invention is to provide a simple, durable, and inexpensive bridge-plate or railway-chair which can be applied to rails of ordinary construction and secured in place by the ordinary spikes now in use for fixing the rails to the ties, and which will effectually prevent any sagging or depression of the ends of the rails in use.

With these objects in view the invention resides, essentially, in a rail-joint bridge consisting of a plate having ends adapted to rest upon the ties and having on its under side a curved strengthening rib whose ends are adapted to bear against the said ties, the said rib having its sides curved inward toward its center, whereby the rib at its center is largest in vertical section and smallest in transverse section, substantially as described.

I have illustrated the invention in the accompanying drawings, in which like letters of reference indicate corresponding parts in all the figures, and in which Figure lrepresentsaside view of arailwayjoint having my improved bridge-plate or chair attached thereto. Fig. 4 is a section on the line 00 0c of Fig. 1. Fig. 2 is an enlarged side view of my bridge-plate or chair, and Fig. 3 is an inverted plan view of the bridgeplate.

In the drawings, A represents the bridgeplate, which is preferably of a length to extend between and have its ends rest upon adjacent ties. The upper face of the plate is flat in order to present an even bearing-surface for the ends of the rails which are designed to rest thereon. The bridge-plate has formed with it or attached to it in a suitable manner an enlarged or swelling portion a forming a longitudinal strengthening-rib, the purpose of which is to materially thicken the plate and serve to strengthen it to support the weight of the load imposed upon the rails at their meeting-points. The width of the plate A corresponds to the width of the bedplate of the ordinary T-rail, and the strengthening-rib (t is preferably of such length that the ends thereof bear against the faces of contiguous ties in order that when the bridgeplate is arranged in proper position between the tops of the ties and the rails longitudinal movement of the plates is prevented. The

sides of the web a are curved inward toward the center, at which point the web is largest in vertical section and smallest in transverse section. By this construction the web is rendered resilient and is also made strongest at the point Where the greatest strain is centered-namely, beneath the meeting-points of the rails. No fastenings other than those ordinarily employed in the construction of railways are required for holding my bridgeplate in place.

When the plate is to be applied to tracks already constructed, it is only necessary to withdraw the spikes which hold the rails to the ties, raise the rails slightly, insert the bridge-plate between the ties and the rails, and replace the spikes. The plate will be held in position laterally by the spikes, and the enlargement a will, as above described,prevent movement in the direction of the rails.

B and 0 represent, respectively, an ordinary angle-bar and fish-plate, forming no part of this invention and being shown merely to illustrate the manner in which my invention may be applied Without interfering with the curved inward toward its center, whereby the ordinary manner of connecting the ends of rib at its center is largest 111 vertical section the rails. and smallest in transverse section, substan- Having thus fully described my invention, tially as described. 5 5 What Iclaim as new, and desire to secure by In testimony whereof Iaffix my signature in Letters Patent, ispresence of two witnesses.
