RAIL-JOINT.

Specification of Letters Patent.

Application filed March 13, 1905. Serial No. 249,780.

To all wlw/11a t may concern:

j Be it known that I, WILLIAM DAvns, a citiaen of the United States, residing at Bloommgton, in the county of McLean and State of Illinois, have invented a new and useful Rail- Joint, of which the following is a specification.

My invention relates particularly to railjoints in that class of construction where the track-rails are laid with abutting ends meeting in a transverse plane, involving the use of ordinary rather than special rails.

My primary obj ect is to make provision in this class of construction against objectionable relative movement of the parts of the joint, so that, in effect, the benefits of a continuous rail are obtained without the necessity of employing specially-prepared rails, thereby insuring greater economy in construction and greater durability in use.

The invention is illustrated in its preferred embodiment in the accompanying drawings, in which- Figure l represents a transverse section of the improved joint taken as indicated at line 1 of Fig. 2 and. Fig. 2 a view, partly in plan and partly in section, the section being taken as indicated at line 2 of Fig. l.

In the preferred construction A A represent rails having adjacent ends squared and abutting or, if desired, separated slightly in the usual mannerto allow for expansion; B B', fishplates of special construction, which cross the meeting plane of the rails and are joined to the webs of the rails by bolts l), and

Bia a base-plate upon which the bases of the end portions of the rails bear. The fish-plates differ from the usual fish-plates in having at their lower portion horizontal outwardlyprojecting flanges t', whose lower surfaces are located above the plane of the lower surfaces of the bases of the rails. The baseplate B2 is wider than the base of the rail, and its lateral projecting edge portions are separated from the horizontal fianges of the fishplates by the spaces b2, as shown. The lateral edge portions of the base plate are joined to the flanges of the fish-plates by bolts b3, and thus is provided a means of securely clamping the base of the rail between the base-plate and the heh-plates, it being understood, of course, that the fishplates find bearings on the base-flanges of the rails. The fish-plates wedge between the top and bottom fianges of the rails in the usual manner, and the rails are thus securely clamped between the fish-plates themselves. In practice the base-plate B2 will rest upon the tie or ties, as will be at once understood.

It readily will be understood by those skilled in the art that my invention provides a construction which not only enables perfect joints to be made when the construction is installed, but enables the same to be maintained under the severest usage. The baseplate in connection with the fis l-plates serves the important function of maintaining the ends of the rails against depression as trains pass over, thereby preventing hammering.

Minor changes' in details of construction within the spirit of my invention may be made. I-Ience no undue limitation should be understood from the foregoing detailed description.

What I regard as new, and desire to secure by Letters Patent, is-

In a rail-joint, the combination with rails, of a flat, flangeless base-plate supporting the adjacent end portions of the rails, fish-plates embracing the rails and having bearings on the base-flanges at their bases, the base-plate having lateral edge portions projecting beneath the fish-plate flanges and separated therefrom by spaces, bolts joining the fishplates and passing through the webs of the rails, whereby the rails are clamped between the fish-plates, and bolts connecting the fishplate flanges with the lateral portions of the base plate wholly outside the edges of the base-flanges of the railsvand having bearingsy on the fish-plate flanges and on the marginal portions of the base-plate outside the base of the rail, whereby the base-flanges of the rails are securely clamped and the springiness of the metal aids in maintaining a tight joint, substantially as and for the purpose set forth.

VILLIAM DAVES.

In presence of- T. W. TRENKLE, W. J. MULLINs.
