RAILWAY-RAIL JOINT.

SPECIFICATION forming part of Letters Patent No. 494,223, dated March 28, 1893.

Application tiled September 21, 1892. Serial No. 446.452. (No model.)

skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in railway rail-joints of the kind in which ish plates are attached to opposite sides of the meeting ends of the rails, and adapted to give the required stability and alignment thereto. We attain these objects in a simple and desirable manner by the means set forth in the following specification and claims, reference being had to the accompanying drawings, in which Figure l is a side elevation of our improved joint-plate and the ends of the rails.k Fig. 2 is a longitudinal section on the line a. of Fig. l. Fig. 3 is a transverse section at the ends of the rails. Fig. 4 shows the joint plates applied to the ordinary T rail. Fig. 5 is a perspective view of our improved joint plate.

Referring to the drawings, A designates the rails, B the joint plates, the web or body of which is adapted to fit between the head and bottom flange of the rail and to form a solid connection or bearing therewith. The said web or body of said plate has a uniform thickness along its bearing edges, but a reduced thickness between the edges for a portion of its length, being thinnest at the ends, the reduction being made by means of shoulders or steps, the several thicknesses having parallel surfaces, which are perforated for the securing bolts and adapted to form level seats for the heads and nuts of said bolts, as shown in Fig. 2, giving a paneled appearance to the outside of the plate, and the greatest amount of metal at the center of the joint, which is a desirable feature. The said joint plate has an approximately horizontal projection c formed integral upon its lower edge, and which extends for a considerable portion-of the length of said plate upon either side of the center. Said projection is bent downward past the edge of the rail fitting thereto and is again bent up parallel with the bottom of the rail, forming a flange t, which extends horizontally underneath the rail, but not in contact therewith. The -said projection e, of said joint plate has a rectangular perforation p through its downward bent portion. The upper face of said perforation is slightly above the bottom line of the rail, and the lower face of said perforation on-a`plane with the upper side of the flange t, underneath the rail, the space between the flange and rail being somewhat less than the width of the perforation.

C, is a broad wedge plate adapted to be driven or forced into said perforation p and between the flange t, and bottom of the rails. Said wedge plate has a slot o, through the thin end, into which a wedge key D, is inserted. The said wedge key is adapted to draw the said wedge plate into a solid bearing between the flanges and bottom of the rails, and at the same time to bring the joint plates firmly against the `bottom edges of the rails.

E, are bolts which pass through the joint plates and web of the rails, and which are adapted to bolt the whole solidly together and in the usual manner. Y

In the drawings we have shown a key driven through a slot in the end of the broad wedge plate for securing the wedge plate and binding the several parts together, lbut it is evident that a screw formed upon the small end ofthe wedge plate with a nut and washer would accomplish the same purpose. We do not, therefore, desire to limit ourselves to the exact construction or proportion of the parts as here shown. From the foregoing description it will be seen thata rail-joint thus formed is adapted to give great lateral and vertical stiffness and support to the ends of the rails,

and in the most economical manner.

Having described'our invention, we claiml. The combination with the rails of the fish plate B, the sectional area ot' which is reduced from the center to the ends by means of successive steps or shoulders adapted to form even or level seats for the heads and nuts of the securing bolts, and provided with the'lateral projection c and the perforated downward bent portion formed integral with said plate and adapted for the insertion of the wedge plate C substantially as and for the purpose specified.

2. The combination with the rails of the fish plate B provided with the successive steps or shoulders formed thereon and the lateral extension e and perforated downward bent portion adapted for' the insertion of the wedge plate C and the upward bent horizontal ian ge t formed integral with said fish plate and the bolts E adapted to secure said fish plate to the rails substantially as and for the purpose specified.

3. In a rail joint the combination with the rails of the fish plates provided with the suooes'sive steps or shoulders formed thereon and adapted to form even or level seats for the heads and nuts of the seouringbolts,and provided with lateral extensions formed integral with said fish plates, and which are bent downward past the edges of the rails, and are bent PAUL PEARSON.
