I BAIL-JOINT.

Application filed March 16,

To all whom it may concern of together.

One ofthe objects of the invention is to construct a rail joint that will distribute the strain brought to bear thereon, due to a train passing thereover. 1 Another object of the invention is to construct the ends of rails, whereby two abutting ends of rails will interlock and abso lutely prevent lateral movement of one rail with relation to the other.

Another object of the invention is to con-. nect the abutting ends of rails to shift the load of a train passing thereover, from one rail' to its adjacent rail, before the load leavesthe first mentioned rail.

A still further object of the invention is to provide a rail joint' of this character which will be strong, durable and inexpensive to construct, eflicient and reliable in operation and well adapted to the purpose for which it is designed.

In the drawings: Figure 1 is a perspective view of the end section of two abutting rails. Fig.2 is atop plan view of the terminals of rails shown separated. Fig. 3 is an end view constructed in accordance with my invention. Fig. i is an enlarged side elevation of the end of one of the rails.

Referring now to the drawing, I "have' shown two abutting rail sections 5 and 6,

' each of which comprises the usual base 5 having an integral web 6, which terminates in a head or tread section} In the construction of the present rail oint, the tread 7 of the rail 6 is cut at an angle of with respect to the edge of the rail, and said out extends 'to the bottom of the tread or to a point where the web 6' merges into the tread 7. At this point a semi-circular cut out portion 11 is provided, said cut-out portion extending transversely of the web, and thewalls adjacent the cut out portion provide a shoulder 9, on one side of the web 6' and a shoulder 9 on the opposite side lying in a plane above the'shoulder 9 for a purpose Specification of Letters Patent.

1916. Serial No. 84,677.

to be hereinafter more particularly described. V

Starting at a point adjacent the semi-circul'ar cut-out portions and continuing through the webs 6 and base 5' of the rail 6, the rail is cut atan angle as at 10, the angle being preferably 45 and in the opposite direction from the angle at which the tread 7 is cut, thereby presenting oppositely. beveled walls, which cooperate with the coinciding walls of the adjacent end of a .rail 5, with the result that, due to the opposed angles of the adjacent rail ends, the rails are interlocked, the 'oint thus pro- Patented Nov.28, iaic.

ducing strong resistance to ateral motion is also cut through the web and base on the same angle, and directly opposite the angle on which the tread portion 10 is out. .A semi-circular cut-out portion 11 is also formed in the rail 5, at the point where the web 12' merges into the tread 10, the walls adjacent said cut-out portion 10 also forming a shoulder 12' 'on one side of the rail and a shoulder 12 on the opposite side, the shoulder 12 lying in 'a plane above the shoulder 12'.

In assembling the device, the abutting ends of the rail sections 5 and 6, are brought together, with the result that the ends interlock, and form a perfect splice joint, avoiding direct vertical alinement of the joint, whereby the joint is greatly strengthened. A suitable wedge or bolt, not shown, may be inserted through the opposing semicircular cut-outs for more securely interlocking the rail ends together against upward movement, said wedge or bolt passing through the 'fish plates or being housed thereby.-' I

It might further be stated that the shoulders 9 and 12' form seats for. a portion of the adjacent rail brought to bear on one rail, throughout the adjacent rail section. After the ends of the rail sections are brought together, shown are positioned adjacent the sides of the rails, and clamped in such position by bolts or similar securing means.

It is to be understood that the details may the usual fish plate sections not 10 thereof adjacent the tread, shoulders formed by the semi-circular cut out portions and shoulders formed on the rail section on opposite sides from the shoulders formed by the semi-circular cut out portions, the shoulders formed by the semi-circular out out 15 portions lying in a plane above the shoulders formed on the opposite sides of the re spective rail sections.

In testimony whereof I afliX my signature.

MAXEY J AGKSON.
