'RAIL-ENnsurroRrINe RAIL-JOINT.

To all whom it may concern:

Be it known that I, BENJAMIN OLHAUP- rrnn, a citizen of the United States, residing at New Rochelle, in the county of West- OllBSfiBI'iLIlCl State: of-New York, have invented certain new and useful Improvements in Rail End Supporting Rail Joints, of which the following is a specification.

' Thisinvention relatesto an improvement in rail joints providing a hard and substantial support for the rail ends to prevent battering out of the joint, and permitting the use of steel.

In the construction of rail joints, particularly of the angle bar type, it is recognized as desirable to use low carbon steel for the rolled splice bars because of the fact that low carbon steel bars will bend under load without fracture or breaking, but nevertheless will permit the flowing of the metal under the ends of the rails. To obviate that defect in the use of low carbon steel bars, the present, and more expensive practice is to make the splice bars of high carbon steel which is heat treated and Oil quenched. That processresults in the production of a splice bar havinghardness and stiffness but at the same time one which is ,quite susceptible, under load and shock, to fracture and breakage.

. Accordingly, anoimportant object of the present invention is to provide a rail joint construction which combines the advantages of rail joints made of both low carbon and high carbon steel while at the same time obviating the defects of both. To that end the invention contemplates the use of low carbon steel bars so designed as to support the rail heads throughout the joint except for a relatively'small area at and adjacent to'the ends of the rails and at such locations to provide substantial rail en'd supports made of high carbon steel, which supports receive the entire shock and wear of the rail ends and thereby prevent the loosening and battering out of the joint.

Furthermore, the improved construction is 7 so designed as to provide a flexible .joint allowing the wave motion of the track to pass through it from rail to rail.

With these and other objects in view, which will be apparent to those familiar with this art, the invention consists in the novel con ruct on, m -inane an arrange rolled splice bars of low carbon Patented oct. 25, 11921.

ment of parts'herein'after more fully described, illustrated and claimed.

Although susceptible of modification, certain preferred and practical embodiments of the invention are shown in the accompanying drawings, in which F'gure 1 1s a perspective view of the rail Fig. 2 is a vertical transverse sectional view at the center of the joint.

Fig. 3 is a horizontal sectional view.

Fig. iris a view similar to Fig. 3 illustrating the change in the formthat may be resorted to in making the supporting shockpiece.

Like references designate corresponding parts in the several figures of the drawings.

The present invention is applicable to any form ofrail joint bar, but for illustrative purposes there is shown in the drawings an angle bar type of rail joint. Referring thereto, the numeral 1, designates the splice bar fitting the fishing spaces of the rails R R, and in accordance with the present invention it is proposed to make the splice bar of the relatively inexpensive low carbon steel which yields to bending stresses but will not readily fracture or break under the loads and stresses transferred thereto from the rails. The head of this splice bar 1, is intended to contact with the under side of the rail heads throughout the entire joint with the exceptionof a relatively small area at and adjacent the meeting ends of the rails and at such location, that is at the center part thereof, the splice bar 1 is bull-dozed or otherwise shaped to provide at the inner side thereof, a socket or housing 2, WhlCh is adapted to receive a vertically arranged supporting shock-piece 3.

The supporting shock-piece 3, preferably is made of high carbon steel, heat treated and oil quenched, the intent of the invention being to have the shock-piece of very hard metal as compared with the softer metal of the splice bar 1, sov as to be able to resist contact with the under sides of the heads of both rails and with the upper sides of the base flanges of both rails. Therefore, the

shock-piece will receive the load from the end of one rail and transmit it downwardly on top of the base of the adjacent rail, the

splice bar proper taking the loads beyond the shock-piece; .Atthe same time, it will have been observed that the construction is such as to render the joint suificiently flexible to permit the wave motion of the track to pass through it from rail to rail.

The form of the socket or housing 2, may be changed and likewise the shape. of the shock-piece varied to suit requirements without departing from the spirit or scope of the invention.

I claim:

1. A rail joint including a fishing bar and a separate shock-piece engaging theunder side of the rail head. 7

2. A rail joint having a relatively soft fishing bar, and a separate relatively hard supporting member engaging the under side of the head of the rail.

3. A rail joint including a fishing bar and a relatively hard supporting shock-piece held by the fishing bar beneath the heads of the rails at the center of the joint.

4:. A rail joint including a fishing bar, and

relatively hard supporting shock-piece inserted in said socket and respectivelyengaging therail heads and rail base flanges.

' 8. A rail joint including a relatively soft fishing bar having a socket and arelatively hard supporting shock-piece insertedin said socket and having its opposite ends respec- --tively engaging with the rail heads and the rail base flanges. V

In testimony whereof I hereuntoaifix my signature 1n the presence of two wltnesses.
