JOINT FOR RAILWAY-RAILS.

SPECIFICATION forming part of Letters Patent No. 504,981, dated September 12, 1893. Application filed March 9, 1893. Serial No, 465,272. (No model.)

T0 at whom it may concern:

Be it known that I, FREDRIOK HERMAN, a citizen of the United States, and a resident of Martinsville, in the county of Copiah and State of Mississippi, have invented certain new and useful Improvements in Joints for Railway-Rails; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a side view of Fig. 2 is a top plan view of same. Fig. 3 is a vertical section on line was Fig. 2. Fig. 4 is a detail view of the joint plate. Fig. 5 is a detail perspective view of the joint, as seen from the inside of the rail.

This invention has relation to railway rail joints, the object being to provide improved means for effecting a secure connection between adjacent rail sections; and the invention consists in the novel construction and combination of parts, all as hereinafter described and pointed out in the appended claims.

Referring to the accompanying drawings, the letters A, A, designate two adjacent rail sections, which I have shown connected by my improved joint. Said joint comprises the outer vertical joint plate B, which is placed against the joint portions of the rail sections, its upper edge being flush with the ball or tread of the rail, said ball or tread being cut away as indicated at a, to receive said plate. Said plate lies flush against the web of the rail, and gradually increases in thickness toward its lower portion, where it joins the integral horizontal base or bottom plate 0, upon which rest the joint portions of the sections. The base D of the rail is also cut away as indicated at b, to receive the plate. The base D at the inner edge of the rail is notched or cut away as shown at c, c, and these notches or cut-away portions receive tongues d, d, of the base plate 0, said tongues being bent upwardly into said notches, and over upon said base. The length of said notches should be about one inch in excess of the width of said tongues, in order to give the rail about one inch movement for expansion and contraction.

F designates the inner fish or joint plate, which is connected with the outer p late B by bolts f. Should these bolts brcak,1t wlll be apparent that the engagement of tongues d, d, and the shoulders of the notches c, c,w1ll prevent the rails from running, and will retain the safety and security of the oint. lhe base or bottom plate 0 is spikedto the ties, and has also on its under surface transverse projections g, which are driven into the ties, and serve to support the joint in case the bolts or spikes break.

In order to prevent the nuts on the oint bolts from becoming loosened by the anof moving trains, I provide a locking device therefor consisting of a bar H of spr ng steel, securely spiked to the ties, and having a series of notches, teeth or project1onsh,w1th which the nuts are turned into engagement.

Inasmuch as the outer joint plate is of greater thickness at the bottom than at the top, the holes for the bolts should be formed at a slight angle, so that the nuts w1ll fit squarely against the said plate. The oint plate B is usually about three feet in length, making a three tie joint. It will be apparent that this plate will prevent the ends of the rails from becoming battered, and prevents any jolt or jar as the wheels pass the 3011113.

A further advantage of the joint is that should the bolts break, together with the tongues d, d, the plate B will still preserve the continuity of the joint, even though the rails be drawn a considerable distance apart.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1S

1. In a railway rail joint, the combination with the rail sections cut away at the outer side at the base and tread, of the joint plate underlying the joint and seated in said cut away portions of the rail sections, and having its upper edge flush with the surface of the tread of said sections, the bottom plate integral with said joint plate and forming a seat for the joint portions of said rail sections, projections on the under surface of the said bottom plate adapted to engage the ties in addition to the usual spikes or bolts, tongues on the inner portion of said bottom plate bent into engagement with cut away portions in the base of the rail sections, the inner fish plate bolted to the rail sections and to the joint plate, and means for locking the nuts of said bolts, substantially as specified.

2. In a railway rail joint, the combination with the rail sections cut-away at the outer side at the base and tread, to receive the joint plate, of the joint plate seated in said cutaway portions and having its upper edge flush with the surface of the tread, the bottom plate integral therewith, the notches or cut-away portions in the base of said sections at their inner sides, and the tongues on said bottom plate bent into engagement with said notches, I 5 and of a. less width than the length of said notches, substantially as specified.

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

FREDRICK HERMAN.
