ORVILLE A. GRIDER. O33 VANDALIA, ILLINOIS.

BAIL JOINT.

Application filed February 5, 19524,.

To all whom it may concern:

Be it known that I, ORVILLE A. GRIDER, a citizen of the United States, residing at Vandalia, in the county of Fayette and State of Illinois, have invented certain new and useful Improvements in Rail Joints, of which the following is a specification.

This invention relates to rail joints, and has for its primary object, the provision in a manner as hereinafter set forth, of a railroad joint so constructed that vibration and lateral movement of the rails at their meeting ends is greatly reduced.

Another object of the invention is the provision in a manner as hereinafter setforth, of a railroad joint so constructed that the meeting ends of the rails have their tread and web in overlapping relation, thus eliminating any chance, in the event that the fish plates become broken, of the rails shifting and becoming out of alinement.

Another object is the provision, in amanner as hereinafter set forth, of a rail joint so set up as to provide for expansion and contraction of the rails, under varying climatic conditions, without the formation of excessive spaces transversely of the rail.

The final object is the provision in a man ner as hereinafter set forth, of a railroad joint which will be as strong as the main body of the rail, of a structure easy to pass, easily assembled, and inexpensive to construct.

In the drawings:

Figure 1 is a top plan view of the rail joint embodying this invention.

Figure 2 is a side elevation thereof.

Figure 3 is a transverse sectional view taken upon the line 33 of Figure 1, and,

Figure 4 is a detail perspective view of one end of one of the rails showing the manner in which the end is molded to fit into a correspondingly molded end of another rail.

Referring now to the drawing in detail wherein like numerals of reference indicate corresponding parts throughout the several views of the drawing, there are shown the abutting ends of two. sections of rail of the usual construction and consisting of the head 1, the web 2 and the base 3. The usual bolt holes 4: are formed through the web of each of the rails.

The end of each rail section at each end Serial No. 690,753.

has its foot finished off at right angles tothe length of the rail forming the transverse vertical abutting end 5. The head and the web portion of each end of the rail is divided through its longitudinal center, and the web and head upon one side of this central longitndinal division is removed and the cutout portion extends rearwardly of the transverse abutting end 5 while upon the other side of this central longitudinal division the web and head are extended forwardly of the end 5 as follows: The web upon one side of the central division is cut backwardly and upwardl to form the shoulder 6 until the underside of the head 1 is reached whereupon the head is finished off to provide the vertical lateral shoulder 7. The other half of the web upon the other side of the central longitudinal division referred to extends outwardly and upwardly at an inclination from the wall 5 as at 8 and where it merges into the underside of the head at the other end of the inclined portion the tread terminates in the vertical abutting wall 9. From this method of formation of the end of the rail it will be seen that there is provided a substantially triangular shaped extension 10 formed of one-half of the web and the head of the rail and overlapping and abutting a similarly formed angled shaped extension of an abutting rail. The angles of the inclined shoulders 6 and 8 are the same and the formation of each end of each rail section is the same with the exception that at one end the extension of the web forward of the end 5 and of the head is upon one side whereas at the other end it is upon the opposite side. The purpose of this is apparent.

l Vhen the rail ends are placed together the ends 5 of the rails abut, the faces of the angle shaped overlapping extensions 10 abut and the extended end 9 of the head of one rail abuts the vertical shoulder 7 in the head of the other rail and the inclined surface 8 of one of the rails rests upon the inclined shoulder 6 of the adjoining rail. Thus the rails, in a way, automatically aline themselves and when so alined lish plates 11 are placed one on either side of the web 9, in a position to overlap the joints and bolts 12 are passed through the apertures 41 in the webs of the rail and through similar apertures in the fish plates ll whereupon nuts 13 are applied to the bolts and tightened to draw the fish plates tightly against the overlapping webs.

From the foregoing description it may be readily seen that there is provided an improved rail joint soconstructed that due to the overlapping relation of the rail ends there is, in a way, a locking action be tween the rail ends which will prevent undue rattling and movement of the rails and further, in the event that the fish plates 11 should become broken, as is often the case, the rails will not shift their position, n0r;caneither rail end sag for in this case if there was any tendency to sag the sagging rail would be supported upon the end of the adjacent rail dueto the overlapping of the shoulders 6 and 8 of theopposed rails.

As aresult of constructing a rail joint in the above described manner the strain on the fish, plates, is greatly decreased thus materially, increasing the strength and etficiency of thejoint as a whole.

While the drawing anddescription set forth: the preferredembodiment of my invention still it is to be understood that the invention is not confined to any strict conformity to the showing. of the drawing, but may be changed and modified so long as such changes and modifications mark no A rail joint comprising in combination,

a pair of opposed track rails, the opposed end terminal portions of said rails each havmg its Web and head out inwardly from one side through one-half their thickness to form the head with a vertically disposed lateral shoulder. extending from the top to the bottom thereon: and the Web with an upwardly inclined shoulder extending from the lowerfree end of the web and terminating at thevlower edgeof the shoulder on the head each of said rails further provided with a substantially triangular shaped extension integralwith'the: head and Web and forming a lengthwise continuation thereof, the extension otone rail positioned inparallelism.with the head and web of the other railythe end and under'edge of said eX-' tensions further opposing said shoulders,

hereto. v
