RAIL-JOINT.

Specification of Letters Patent.

Patented Apr. 8, 1919.

Application filed November 21, 1918. Serial No. 263,575.

To all whom it may concern:

Be it known that I, SAMUEL A. BOYD, a citizen of the United States, residing at Sasakwa, in the county of Seminole and State of Oklahoma, have invented certain new and useful Improvements in Rail-Joints, of which the following is a specification.

This invention relates to rail joints and has for its object to provide a comparatively simple and thoroughly eflicient device of this character, by means of which the confronting ends of rails in a line of track may be quickly and conveniently coupled and said rails securely held in longitudinal alinement under all conditions of service.

A further object of the invention is to provide a safety joint, the rail ends of which are provided with interlocking parts disposed beneath the rails and so constructed as to prevent sagging of the abutting ends thereof, thereby obviating the necessity of tamping up low joints and effectually preventing pounding and mutilation of the rail ends incident to the travel of cars and other rolling stock thereover.

The invention further aims to provide a rail joint, the rail ends of which are interchangeable so that when one side of any rail becomes worn or otherwise impaired from constant use the position of said rail may be reversed whereby to present a fresh track surface to the car wheels.

The invention further contemplates a joint which may be applied to the standard type of rail without necessitating any structural changes therein and in which wear and strains on the angle bars and securing bolts are reduced to a minimum.

A still further object is generally to improve this class of devices so as to increase their utility, durability and eliicienc Figure 1 is a perspective view 0 a portion of a railroad track provided with a rail joint constructed in accordance with the present invention;

Fig. 2 is a. detail side elevation of one of the joints;

Fig. 3 is a bottom plan view;

Fig. 4 is a detail perspective view of abutting ends of mating sections showing the construction of the locking device;

Fig. 5 is a detail transverse sectional view.

The im roved joint forming the subjectmatter 0 the present invention is principally desi ed for connecting the con fronting en a of railway rails and' by way.

of illustration is shown applied to a section of track in which 5 designates the rails, 6

the abutting ends thereof and 7 the crossties to which the rails are secured.

Secured to or formed integral with the base flanges 8 of the rails at the abutting ends thereof are depending enlargements indicated as a whole at 9, said enlargements being provided with interlocking parts, the construction of which will be more fully explained hereinafter. The enlargements 9 register with each other when the rails are assembled and serve to reinforce and brace the rails at the abutting ends thereof so as to effectually prevent sagging of the rail ends and pounding or mutilation of said ends incident to the passage of cars and other rolling stock thereover. When the rails are assembled, the extensions 9 fit between and bear against the'adjacent crossties 7 and in which position they are se- I -urely held by means of spikes or other fastening devices 10 driven into the crossties and engaging suitable angle bars or fish plates 11, as shown. are provided with elongated openings 12 for the passage of securing bolts 13 which latter extend through the webs of the rails in the usual manner so as to permit expansion and contraction of the rails due to temperature changes.

The rear end of the enlargement 9 of each rail preferably extends the entire width of the base flange thereof and is cut away to form a horizontally disposed lip 14 also preferably extending the entire width of the base flange of the rail, as shown. Spaced from the lip 14 is a substantially L-shaped extension 15, the long arm of which is preferably substantially one-half the width of the base flange of the rail, while the short arm of the extension extends substantially the entire width of the base flange of the rail andhas its under side cut away to form a transverse locking lip 16 adapted to fit within the groove formed by the locking lip 14 of a'mating rail end when the rails are assembled. The extension 15 is spaced from the adjacent lip 14 to produce an intermediate passage 17 which accommodates the short arm 18 of the adjacent L-shaped extension so that when the rails are assembled the inner'faces of the extensions 15 will abut and thus prevent lateral displacement of the rail ends. It will here he noted that the extensions 15 project longitudinally beyond The angle bars 11 the abutting ends 6 of the rails so that when the rails are assembled the extension 15 of one rail will overlap the base flange'of the adjacent rail. and thus form a firm anchorage and reinforcement for the abutting ends of said rails. The recesses 17 open through the opposite longitudinal edges of the rails so that the rails may be readily-assembled by causing the li s 16 to register with the re- 10 cesses formed y the lips 14 and then pressing laterally on the rail ends until the adjacent faces of the extensions 15 abut and 1n which position the rails will be securely held in longitudinal alinement. It will, of 15 course, be understood that there will be sufficient play between the extensions and the lips 14 to allow for expansion and contraction of the rails under temperature changes. The locking members are identical in con struction with the exception that the extension 15 at one end'of each rail is arranged on one side of the longitudinal axis of the rail, whereas the extension on the opposite end of the rail is disposed on the other'side of the other longitudinal axis of the rail. By making the locking members in this manner the railends are rendered interchangeable so that should the tread surface of a rail bei come worn or otherwise impaired from constant use the position of the rail may be readily reversed thereby to present a new tread surface to the car wheels. It will, furthermore, be noted that the locking members comprisingmy improved joint are disposed entirely beneath the base flanges of the rails so as to render it unnecessary to out or otherwise weaken the vertical webs or tread faces of the rails and permitting the device toxbe used in connection with the standard 40 type of rail Without necessitating any structural changes therein, it being merely necessary to weld or otherwise secure the interlookin parts on the base flanges of the rails as wil be readily understood. Moreover, as

the interlocking members comprising my improved joint are disposed beneath the rails at the abutting ends thereof, strain and wear on the bolts and angle bars is reduced to a minimum.

A joint constructed in accordance with the present invention may be quickly coupled, and effectually prevents sagging or low joints at the abutting ends of the rails with consequent ounding and damage to both. the

rail endsand Wheels'of the rollingstock.
