RAIL-JOINT FOR RAILWAY-RAILS.

Specification of Letters Patent.

Patented May 24, .1910.

Application filed. September 10, 1909. Serial No. 517,132.

To all whom it may concern:

Be it known that we, RAYMOND C. DOLE and ED ELLIs, both citizens of the United States, residing at Guthrie, in the county of Logan, in the State of Oklahoma, have invented new and useful Improvements in Rail-Joints for Railway-Rails; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form part of this specification.

Our invention relates to improvements in rail joints for railway rails.

The primary object of our present invention is to provide a comparatively cheap, simple and eflicient joint for railway rails, constructed and arranged to bridge the joint so as to practically form a continuous rail, to allow for the usual and all necessary expansion and contraction, to permit the detaching of either rail therefrom without disturbing either the other rail or the joint, and which is practically indestructible, and secures a substantially noiseless tread at the joint.

Our invention consists of a lateral enlargement of the webs of the meeting ends of the rails, which enlargements have registering vertical slots which near their lower portion have upon each side thereof a lateral recess, a removable plate loosely mounted in the said slots, and a pair of smaller plates loosely mounted in the recesses respectively.

The principal novel feature of our invention resides in the construction and cooperative relation of the slotted rail ends End the interlocking removable plates there- Similar reference numerals indicate like parts throughout the several views of the drawings in which Figure 1 is a perspective view of our invention in position interlocking the meeting ends of the railway rails partly broken away, and showing the relative arrangement of the interlocking plates. Fig. 2 is a cross section of the same on the line 40-00 of Fig. 1. Fig. 3 is a horizontal section of the same on the line y-g of Fig. 1 to show the relative arrangement of the thickened web and the interlocking parts therein, which are not shown in section. Fig. 4 is a detail perspective of the central plate or key and Fig.

5 is a perspective view of one of the smaller interlocking plates.

The railway rails 1 are of the usual or any proper construction and have the web 5 thereof laterally enlarged or thickened at and near their opposite sides, as shown at 10 in Figs. 1 and 3. These thickened ends are provided with a longitudinal vertical slot 2 which passes through the ball 3 of the rail and downward to the base 4 of the rail. The slots 2 of the abutting ends of the rails are coincident or in register, and are provided at their lower portions and upon each side thereof with a lateral longitudinal recess 6 in which the respective plates 7 are loosely arranged. In the coincident slots 2 is loosely mounted the key or plate 8 which is of a length slightly less than that of the slots in which it is mounted'to compensate for unequal expansion and contraction. The lat eral recesses 6 for the plates 7 are preferably of a less depth than that of the recess 2, as shown in Fig. 3, and the key or plate 8 has its upper edge at all times flush with the tread of the rails as shown in Fig. 1.

In the employment of our invention it is obvious that the key 8 and the plates 7 together firmly interlock the abutting ends of the rails against lateral displacement or derangement, and that the key 8 perfectly bridges over the space between the ends of the rails, and thereby forms a practically continuous tread, and thus completely eliminates the usual jar in passing over the rail joint. It is also evident that either rail can readily and conveniently be removed or replaced without any interference with the other abutting rail or with the interlocking plates.

A rail joint thus constructed is strong, durable, cheaply constructed and easily employed, and bridges the space between the ends of the rails by a continuous tread.

Having thus described our invention what we desire to secure by Letters Patent is:

1. A rail joint for railway rails consisting of two abutting rail ends having a thickened web, and provided with coincident vertical slots having longitudinal recesses upon opposite sides thereof; a key or plate loosely mounted in the said vertical slots with its upper edge flush with the tread of the rails; and plates removably mounted in the said recesses respectively.

2. In a rail joint the combination of two railway rails having their abutting ends provided with coincident vertical slots having and State of Oklahoma, this 20th day of AuilpOIl bolth sidelzs andlnear the bOttOILl thelieof gust, 1909.
