RAIL-JOINT.

SPECIFICATION forming part of Letters Patent No. 699,903, dated May 13, v1902. Application filed March 3, 1902. V SerialNo. 96,502. (No model.)

To all whom it may concern:

Be it known that 1, JOHN THRAILKILL, a citizen of the United States, residing at Dexter, in the county of Dallas and State of Iowa, have invented certain new and useful Improvements in Rail-Joints; 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 theart to which it appertains to make and use the same.

This invention aims to providea rail-joint of novel formation which will present a continuous up-bearing surface at the juncture formed between the ends of adjacent rails, the joint being braced against both vertical and lateral stress. I

For a full description of theinvention and the merits thereof, and also to acquire a knowledge of the details of construction of the means for effecting the result, reference is to be had to the following description and drawings hereto attached.

While the essential and characteristic features of the invention are susceptible of modification, still: the preferred embodiment of the invention is illustrated in the accompanying drawings, in which- 7 Figurel'isa perspective viewof a rail-joint embodying'the invention. Fig. 2 is a transverse section. Fig; 3 is a perspective view. of one member of the joint. Fig. 4 is a perspective view of the other member of the joint. Fig. 5 is an end view of both members of the joint.

Corresponding and like parts are referred to in the following description andindicated in all the views of the drawings by the same reference characters.

The joint comprises the members 1 and 2, which represent the ends of ad jacentrailroadrails. The member 1 has spaced extensions 3 in line with side portions of the foot or base anda mortise 4, extended inward for a short distance from the, extremity, said mortise opening upward through the tread of the member and having its side walls slightly upwardly flared. The foot of the member and each side of the web are cutaway for a short distance from the extremity to form a space to receive the ofiset portion 5 of the spliceplate 6, which is bolted against the side of the joint and firmly attached to a tie.

The member 2 has a longitudinal extension 7 to snugly fit the mortise 4, the sides of said extension being slightly-upwardly diverged to conform to the Hare of the sides of the mortise 4. The foot is cut away' at each side of the web, as shown at 8, to receive the extensions 3, which embrace opposite sides of the web and in conjuction with the extension 7 prevent lateral movement of the members comprising the joint. The extension 7, fitting the mortise 4, prevents any vertical play of the members and insures the formation of a'contiuuous surface for supporting the walls when passing over the joint, thereby preventing any jar or shock, such as commonly experienced in railways having the adjacent ends of rails abutting simply without anyinterlocking.

When the members are fitted together, a space is provided at each side of the web and extends equally to the right and to the left is claimed as new isv 1. In a rail-joint, a member having spaced basal extensions and a longitudinal mortise extended inward from the extremity of the rail and opening upward through the treadsurface, and the other member having the foot of the rail cut away at each side of the web to receive the aforesaid extensions, which embrace the sides of the web, and a longitudinal extension to fitwithin the said mortise, substantially. as set forth.

2. Ina rail-joint, a member having spaced longitudinal extensions, and a mortise extended inward from the extremity and having its side walls upwardly flared, and the mating member having the foot'cut away at each side of the web to receive the aforesaid spaced extensions and havingalongitudinal extension with its sides upwardly diverged to snugly fit the aforesaid mortise, substantially as set I Wings to be attached to a tie, each of the forth. splice-plates having an offset portion to fit a 3. In a rail-joint, a member having spaced cut-away part of the foot of the rail member longitudinal extensions and a mortise, the forming the joint, substantially as set forth. 5 mating, member having a portion of the foot In testimony whereof I afiix my signature 15 cut away upon each side of the web to receive in presence of two witnesses.

the aforesaid spaced extensions and having JOHN THRAILKILL. [L. s.] a longitudinal extension to snugly fit said Vitnesses: mortise, and splice-plates seeu red to opposite S. H. SMITH,

IO sides of the joint and having oifstanding C. E. NOLTE.
