RAIL-JOINT.

Specification of Letters Patent.

Patented. Ian. 12, 1909.

Application filed May 21, 1908. v Serial No. 434,126.

To-all whom it may concern.

I Be it known that I, ARTHUR Swanson, a

citizen of the United States, residing at Manor, in the county ofTravis and State of Texas, have invented certain new and useful Improvements in Rail-Joints, of'which the followin is a specification, reference being had to t e accompanying drawings.

My invention relates to im rovements in joints for track rails and its 0 ject is to provide the meeting ends of two rails with a simple and practical scarf or interlocking connection which will eflectually hold them in perfect alinement, and at the same time permit them to be readily disconnected.

With the above and other objects in view, the invention consistsof the novel features of construction and the combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawings, in which Figure 1 is aside elevation of my improved rail' joint; Fig. 2 is a vertical transverse section taken on the irregular plane indicated by the line 2-2 in Fig. 1; Figs. 3 and 4: are perspective views of the-ends of'the track rails; and Fig. 5 is a detail view ofthe locking key or wedge. f

In the drawings 1 and 2 denote the adjacent ends of two track rails of the usual T- 'In constructing my improved joint I cut away a portion of the end of the web of the rail 1 so as to leave the base flanges Iprojectform a centrally disposed longitudinally extending slot or opening 6. of the head of the rail 1 so as to leave a portion 7 of the web projecting and I further round or bevel the upper end 8 of said proj ecting portion 7 of theweb. The other track rail 2 has its abutting end shaped to engage the end of the rail .1- and this is accomplished by cutting away the base flanges of the rail slot 6 in the rail 1 and to have its'lower end 2 so as to receive the projecting ortion 5' of the base flanges ofthe rail 1. T e recessin or cutting away of the base flanges of the rail 2 leaves the web 1portion of the same rojecting'and upon t e bottom of this pro ectin'g ortion 9 of the web is formed a depending ug or projection 10 adapted to enter the receive a locking key or wedge 12, as pres- I also cut away a portion.

project. beneath the bottom faces of the base flanges of the rail 1.

In the projecting lower end of the lug 10 is formed a transverse slot or opening 11 to ently explained. The outer end of the proje'cting portion 9 of the web of the rail 2 isv .cut away to provide a projecting portion or end 13 u on the head of said rail, said portion 13 eing adapted to project over the projecting portion 7 of the web of the rail 1 and being formed in its bottom face with a recess 14 shaped to receive the u per end 8 of said portion 7. By shaping t emeeting ends of the rails 1, 2 as shown and described, it will be seen that'the rail 2 may be readily engaged with the rail 1 by placing its projecting portion over the recessed portion of the rail 1 and dropping the lug 1O intothe slot 6, and that when the rails are thus engaged they willbe held in perfect alinement and against longitudinal or transverse shifting movement. The key 12 serves to hold the ends of the rail against vertical movement with respect to each other and is in the form of a long tapered or wedge-shaped plate adapted to be driven transversely through the slot or opening 11. in the lug 10 and to engage the bottom face of the projecting portions 6 of the base flanges of the rail 1.

When driven into the slot or opening 11 it I to provide a projecting base flange portion,

the latter being formed with a central 0 ening, the other. rail having its Web and ase flange portionscut away, the projecting web portion being provided with a depending lug to project throughthe opening in the base portion of the other rail, the projecting lower portion of the lug being formed with a transverse opening, and a key arranged in the latter to retain the lug in its opening.

2. A rail joint comprising two rails, one

having its head and web portions cut away to provide a projecting base flange portion, the latter being forme with a central 0 ening, the other rail having its web and ase 11o 3. In airail joint, the combination of twotrack rails, one having its head and web portions cut away to provide a projecting web portion, the latter having its upper end rounded or beveled and the projecting base flange portion being formed with a centrally arranged opening, the other rail having its Web and base flange portions cut away to provide a projecting Web ortion and a projecting head portion, the atter being formed in its under face with a recess to receive the upper end of the rojecting web portion on the first mentioned rail, the bottom of the 'projeoting web portion of the second mentioned rail being formed witlra depending lug to pass through the openingin the base flange portion of the first mentioned rail and having in its projecting end a transverse opening, and a locking key passed transversely through the opening in the lug.

In testimony whereof I hereunto aihx my signature in the presence of two witnesses. ARTHUR SVVENSON. Witnesses:
