UNITED STATES PATENT OFFICE.

RAIL JOINT.

Application led May 13, 1924. Serial No. 713,035.

To all whom t may conocia.'

Be it known that I, JOSEPH S. BEAN, a citizen of the United States, residing at Mill Village, in the county of Sullivan,

State of New Hampshire, have invented a new and useful Rail Joint; and I do hereby 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.

The invention relates to rail joints, and has for its object to provide a device of this Character wherein adjacent railroad rails are secured in transverse recesses in the end of a cross tie by means of a wedging member, thereby obviating the use of fish plates and bolts, consequently reducing the cost of upkeep to a minimum.

The tie and rails are preferably forme from a metal, which will not corrode, for instance as aluminum, and will not rapidly become damaged or worn incident to corrosion as is now the main difculty with metallic ties.

A further object is to provide the outer edges of the rail flange with bevelled surfaces and with which bevelled surfaces a tapered key cooperates when driven into one side of the recess in the tie, said tapered key being provided with a flange which overlies the upper side of the adjacent flanges of adjacent rails.

A further object is to bevel downwardly and inwardly the inner side of the tread of the rails, thereby presenting a minimum amount of surface with which the flange of a wheel engages and consequently reduces the friction to a minimum.

With the above and other objects in View the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the. invention.

In the drawing:

Figure l is a side elevation of one end of the tie showing the same partly in vertical longitudinal cross section, and a rail disposed therein.

Figure 2 is a top plan view of a tie, showing abutting adjacent rail ends disposed therein.

Figure 3 is an end view of the tie, showing adjacent rail ends ends. secured therein.

Referring to the drawing, the numeral l designates the cross tie, which is preferably formed from a noncorrosive metal, such for instance as aluminum and 2 the conveXed underside thereof, which rests in a road bed, and by being conveXed is more positively held by the roadbed. The ends of the tie l are provided with transversely disposed recesses 3 3 having side channels 4L and in which recesses the adjacent ends of rails 5 are received with their' flanges G within the channels 4. The outer edges of the flanges 6 of the rails are bevelled as shown at 7 for engaging the downwardly and outwardly inclined outer' wall 8 of the recess 3, and forming a bearing surface for the flange 9 of the angular wedge key l0, which is adapted to be driven into the inner channel 4 for wedging the adjacent rails 5 outwardly against the inclined surface 8. Thus it will be seen that the rails at opposite ends of the tie will be positively held in accurate spaced relation, and against spreading. It will also be seen that the use of fish plates or bolts is eliminated, consequently the eX- pense of maintaining track walkers for tightening fish plate bolts is also obviated.

lVedge keys l0 at opposite sides of the track are preferably driven into position in opposed relation, thereby counteracting the tendency of the rails creeping incident to trafiic moving over the same.

The invention having been set forth what is claimed as new and useful is A rail joint comprising a railway tie, adjacent abutting rail ends disposed in a re- Icess in the end of said tie, flanges carried by said rails and disposed in channels in the walls of the recess of the tie, the outer edges of said flanges being bevelled, the outer flanges of the rails having their bev elled edges in engagement with a bevelled surface at the outer end of the channel of the recess, an angularly shaped tapered wedge having a narrow and a wide flange, said narrow flange of the wedge engaging a bevelled surface in the other channel and the bevelled edges of the anges of the rails neme to this specification n the presencel of at the inner sides of the rails, said. Wide two subscribing Witnesses.

flanoe of the enfmlarly shaped wedo'e overlynV the upper ldes of the inner flznges of JOSEPH S' BEAN' 5 the adjacent rails and the `upper wall of the fitnessesg tie recess. GEORGE F. CRANE,

In testimony whereof I have slgned my M. JULIA CRANE.
