RAlL JOlNT FOR STREET CAR TRACKS.

:IIEEGIFIQAUCIQN forming part of Letters Patent No. 719,010, dated January 27, 1903.

Application filed May 2'7, 1902.

To all whom fl; may concern:

Be it known that I, JOHN JONES, a citizen of the United States, residing at Denver, in the county of Arapahoe and State of Colorado, have invented a new and useful Rail-Joint for Street-Car Tracks, of which the following is a specification.

My invention relates to railway-rails, and more particularly to the ends or meeting faces of each section composing the rails, one object of the invention being to provide a rail made up in sections and joined at itssections in such a manner that wearing of the top and bottom surfaces of each section at its jointnre is obviated to a marked degree.

Another object of the invention is to provide a rail-section free of projections and recesses, thereby prod ucing an inexpensive railsection without necessarily employing complicated mechanism.

A still further object of the invention is to provide a rail in sections in such a manner that a binding action of one section upon the adjacent section takes place at the jointure thereof when weight is brought to hear thereupon, means being provided to prevent lateral movement of one section with relation to the other.

The invention is still further designed to provide a construction wherein the weight brought to bear upon one section will act simultaneously upon the adjacent section of the rail, preventing the movement of one section beneath the plane of its adjacent section.

Other objects and advantages of the inverttion will be apparent and understood from the following description when viewed in connection with the annexed drawings, in which- Figure l is a side view of portions of two rail-sections slightly separated, each section illustrating an inclined end corresponding to the inclination of the other; and Fig. 2 is a similar view illustrating the ends of the railsections joined at their ends and held in such position.

Like characters of reference designate corresponding parts in the views of the drawings.

Now taking up the preferred embodiment of my invention as shown in the drawings,

Serial No. 109,184. (No model.)

the reference characters A and B designate the rail-sections, the letters a h c g indicating the upper surfaces of the rail-sections, and bfd e the bases thereof, the inclined end a b of the rail A adapted to rest and bind upon the corresponding inclined end 0 d of the section B. The sections are thus held and prevented from lateral movement with relation one to the other by means of a fish-plate F, it being understood that another plate (not shown) may be placed upon the opposite side of the sections, both plates having alining perforations and bolt-s D piercing the said plates and the rail-section through the perforations t', as shown. By this arrangement there is afforded a tight jointure of the rail-sections, and in the event of the rails being embedded in soil or concrete, and which is usual, there will be but little if any expansion and contraction of the several parts described.

In the placing of the rails the question of the greatest amount of traffic is considered and the sections so disposed with relation to each other that the car or train passing over the rails in the direction shown by the arrow indicating the direction of the greatest amount of traffic will not force the upper surface of one section below the level of the other section. On the other hand, it is evident that the inclined end of one section will bind tightly against the correspondingly-inclined end of the other section. It will also be noted that the wheels of the car or cars will bear upon each section at the same timethat is, before a wheel leaves one section it has pressure upon the other section-the inclinations of the ends of the sections affording this desirable feature of the invention.

From the foregoing it will be seen that the abutted ends of the rail-sections rest one upon the other, that each section is free from projections and recesses and set at an angle to the vertical with their ends in mutual contact throughout their entire surfaces, the joint having its transverse directions lying at right angles to the vertical plane of the sections, fish-plates acting upon each section to prevent lateral displacement of one section with relation to the other section.

I claim- 1. A rail-joint consisting of rail-sections having abutted inclined ends overlapping each other, said ends presenting inclined meeting faces flat and flush throughout their entire surfaces and forming a joint, the transverse directions of which are at direct right angles to the vertical plane of the rail, said transverse directions being arranged one in advance of the other, and fish-plates secured on either side of the rail to prevent lateral displacement of one section With relation to the other.

2. A rail-joint comprising opposite rail-sections, the abutted ends of which are free from projections and recesses and set at an angle to the vertical with said ends in mutual contact throughout their entire surfaces and the joint formed thereby having its transverse directions disposed at right angles to the vertical plane of the rail-sections, and fish-plates overlapping the joint at opposite sides of the rails and connected to both of the latter.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN JONES.
