Application filed June 23, 1911. Serial No. 634,889.

To all whom it may concern:

Be it known that I, SALVATORE SANNA, a citizen of the United States, residing at Olinghouse, 1n the county of Washoe and State of Nevada, have invented new and useful Improvements in Railway-Joints, of which the following is a specification.

The present invention relates to certain novel and useful improvements in railway joints.

In carrying out my invention, it is my purpose to provide a railway joint which will firmly and safely secure the contiguous ends of two sections of rails, and at the same time the construction and arrangement are such that jarring and wear and tear incident to the rolling stock traveling over the rails at the joint is obviated to a great en-v tent.

Still a further object of my invention is to provide an improved form of railway chair adapted to embrace the, rail sections at the joints, saidchair having a plate interposed between one side thereof and the rail joints, such plate extending to or slightly above the tread surface of the ball of the rail whereby the wheels of the car trucks will travel on the upper part of the chair at the joints, thereby avoiding wear and jar upon the rails. 1

It is also my purpose to provide an im-' proved rail joint embracing the desired features of simplicity, strength and etliciency coupled with economy in the cost of manufacture and installation.

Still a further object of myinvention is to provide a form of rail joint wherein the use of bolts and holes in the rails at the joints is avoided.

With the above recited objects and others .of a similar nature in view, my invention consists in the construction, combination and arrangement of parts set forth in and falling within the scope of the appended claim.

In the accompanying drawings :F igure 1 is a vertical cross sectional view takenthrough a rail joint embodying my improvements. Fig. 2 is a view in side elevation of the outer face of two adjoining sections or rails having my joint applied thereto. Fig. 3 is a top plan view of the same. Fig. 41 is a detail perspective view of the fish ate; p Referring to the accompanying drawings in detail the letter A 1 designates theends of two rail sections designed to be joined, the numeral 1 indicating the base of the rail sections, 2 the vertical web thereof and 3 the ball while 4 is the tread surface of the ball.

My improved rail chair is indicated as an entirety by the letter C, and comprises a vertical web 5, merging in the base 6 upon which the basev of the rail sections rest.

0 erlapping the top of the base of the rail se tions and conforming to the contour or inclination thereof is the horizontally inclined section 7 of the chair, merging in the vertical wall 8, the upper end 9 of the latter abut-ting against the under surface of the ball of the rail while said vertical wall 8 lies in flush contact with the adjacent surface of the web of the rail. On the opposite side of the rails the-base 6 is provided with a vertically extending wall 10, which is slightly inclined and is provided with thickened bolt receiving portions 11, each having a threaded bore 12 designed to receive the threaded shanks 13 of the bolts 14.

Interposed between this vertical wall 10 and the sides of the rail sections is a fish plate 15 having the inwardly extending lugs or members 16 designed to abut against the adjacent surface of the vertical web of the rail, said plate terminating at its upperedge in an enlarged curved portion 17 having a tread surface 18 which is slightly inclined outwardly and is designed to lie a short distance above the tread of the rail ends so that when the wheel W of the car truck passes over the joint it will ride upon the tread of the chair and thereby save wear and jar upon the rail joints.

The above is a description of the construction of my improved rail joint, and the manner of employing the same will be readily apparent to those skilled in the art. The two sections of the rails to be joined are placed with their ends contiguous in the usual manner, and within the rail chair. The fish plate 15 is also inserted as is shown in Fig. 1 and the bolts 14 are then screwed up and tightened to force the members 16 of the chair firmly against the webs of the rail sections while the concaved surface 19 of the enlarged upper portion of the chair fits-over the sides of the balls of the rail. When the parts are so assembled, a safe, secure, permanent joint is formed without resorting to the use of bolts or holes in the fish plates and in the webs of the rail sections.

Having described my v invention, I claim The combination with rail sections to be joined, of a chair therefor comprising a base plate, a wall extending from one side edge of the base plate and adapted to bear upon one side of the meeting rails, a second wall member extending upwardly from the opposite side edge of the base plate and spaced apart from the webs of the rails and r0- vided with thickened bolt receiving port ons each having a threaded bore, a plate interposed between said wall member and the adjacent webs of the rails and having inwardly extending longitudinally disposed members spaced apart and adapted to bear against the webs and spaced from the adjacent edges 20 of the plate, and boltspassing through the bores of the said thickened bolt receiving portions of the second wall member and bearing against the said plate .for holding the latter in sections. y

In testimony whereof I aflix my signature in presence of two witnesses.
