RAILWAY-RAIL JomT.

Specification of Letters Patent.

Patented Dec. 8', 1908.

Application filed March 11, 1907, Serial No. 361,783. Renewed September 3, 1908. Serial No. 451,573.-

T 0 all whom it may concern:

Be it known that I, HENRY M. CosE-Y, a citizen of the United States, residing at Sterling, in the county of Whiteside and State of Illinois, have invented certain new and useful Improvements in Railway-Rail Joints; and I do declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled in the art to which itappertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to joints for railway rails, and deals more specially with a new and useful form of the fish-plates by which the ends of two adjacent rails are held in place.

By the use of my device a solid joint is secured, wherein the fishlates engage the rails throughout the entire ength of such (plates, and at the same time a force is exerte upon the bolts by which the parts are held to-' gether which prevents the loosening of the nuts thereon, and also compensates for any wear u on the bolt-heads or nuts.

e the invention, as a means for holding the ends of the rails in place, is as efiective as joints which are commonly in use, its production calls for the use of less material than is required in the ordinary fish-plate, and without any sacrifice of strength or durability.

The eculiar construction and operation of my evice will more fully appear in the following specification, reference being had to the drawings accompanying the same, wherein Figure 1 is a lan view with the vertical portion of the rai in section, before the tightening of the joint. Fig. 2 is a similar view with the parts drawn together as in use. Fig. 3.is a side elevation of the joint. Fig. 4 is a vertical cross-section in the line wx of Fig. 5 is a vertical cross-section in the line y--'y of Fig. 2.

Similar numbers refer to similar parts throughout the several figures.

1 represents the base of the rail, 2 the vertical portion, and 3 the tread thereof, the ends of two adjoining rails being shown in the first three figures.

4 is the fish-plate, provided with a flange 5, resting on the base of the rail. The plates 7 bolts.

4 are secured to the rails and to each other in the usual manner by means of bolts 6 passin through perforations in the fish-plates an corresponding holes in the rails at each side of the junction thereof.

On each side of the point where the ends of the rails contact the inner face of the late 4 is provided with a recess 7, of su cient length to embrace two or more of the bolts 6, whereby that portion of the plate which is cut away to form the recess is rendered sufli ciently flexible to permit the drawing of the same inwardly upon the tightening of the The width of the recesses 7 gradually decreases toward the ends thereof, and also towards the bottom, and when the bolts 6 are sufiiciently tightened the faces of the recesses 7 are in contact with the vertical portion 2 of the rail throughout such faces, forming a continuous enga ement of the rails by the inner face of the sh-plate, as shown in Figs. 2 and 5. This forms a solid and rigid joint, which is greatly to be desired in railway rail connections of this kind.

The plate 4 is preferably formed of metal possessing a certain amount of flexibility, so that when the bolts 6 have been fully tightened by action of the nuts thereon, the tendency of that part of the fishlate surrounding the bolts will be outward y, thus bearing upon the inner faces of the heads of the bolts and the nuts thereon. However, fish-plates of the same general form which are now in use can be provided with the recesses 7, and will be operative to a certain extent.

A common fault with joints of this class is found in the bolts which hold the parts together becoming loose, through wearing of the arts caused by rust or other means. It is obvious that in my invention this difficulty is overcome through the outward force exerted on the heads and nuts of the bolts at all times by that portion of the plate 4 in which they are seated.

The under side of the tread 3 of the rail is usually provided with a bevel inwardly and downwardly, as shown in Figs. 4 and 5, and the upper edge of the plate 4 provided with a corresponding bevel, in order to form a close engagement of the rail. In order that that portion of the plate 4 which is provided with the recess 7 may be drawn inwardly without interference from the rail it is therefore necessary to form slight recesses 8 in the upper reak in the rails, and I prefer to form the recesses 7 of sufficient length to embrace both of the bolts on the same side of the break, in order that that portion of the plate which is cut away to form the recess may have the requisite amount of spring. To provide each of such bolts with a recess corresponding to the recesses 7 would not be feasible.

If desired, the joint can be provided on one side of the rail with my device and on the other side with the older style of plate, but it is preferable to use my invention on both sides of the rail, as shown in the figures, by which means double the amount of force is exerted on the bolts 6 as is attained by the use of the single plate.

When the plate 4 is first placed in position its inner face engages the vertical portion of the rail at all points except where the recesses 7 are provided, and in tightening the bolts the inward movement of that part of the plate which has been cut away is greatest at the upper edge thereof, the lower part of the plate 4 having very little movement. Thus any danger of such plate breaking away from the flange 5 is obviated. It will also be seen that the use of the flange 5 is not necessary to the successful operation of the device.

ceases What I claim as my invention, and desire to secure by Letters Patent of the United States, is:

1. A railway rail joint, comprisinga fishplate, adapted to hold in place the ends of two adjacent rails, and provided on its inner face with a pair of recesses, each of such recesses including all of the bolts on one side of the rail joint; said plate being further provided in its upper edge with a pair of recesses, corresponding in position with said firstnamed recesses, and permitting those portions of said plate which are adjacent to the recesses to be drawn inwardly into contact with the rails, substantially as shown and described.

2. In a railway rail joint,a plate 4, adapted to hold in position the ends of two adj acent rails, and provided on its inner face with a recess 7, formed to include two or more of the bolts 6 by which said plate 4 and the rails are united; said plate being further provided in its upper edge with a recess 8, adjacent to the recess 7, and permitting that portion of the plate 4 which surrounds the bolts 6 to be drawn inwardly into contact with the rail, substantially as shown and set forth.

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