RAILWAY-RAIL JOINT.

Application filed May 31, 1922.

To all who 27b it may concern:

B e it known that we, ROY P. OWEN and DANIEL B. S'rnALnY, citizens of the United States, residing at Waukesha, in the county of lVaukesha and State of Wisconsin, and Crown Point, in the county of Lake and State of Indiana, respectively, have invented certain new and useful Improve-1. ments in Railway-Rail Joints, of which the following is a specification.

This invention relates to rail joints, and has for one of its objects to provide a device of this character wherein means are provided for holding the rails from longitudinal and transverse displacement, while at the same time providing for the necessary longitudinal expansion and contraction caused by the change of temperature in the atmosphere.

With these and other objects in view the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claim, and in the drawings illustrative of the preferred embodiment of the invention:-

Figure 1 is a plan view of the improved joint,

Fig. 2 is a section on the line 2-2 of Fig. 3,

Fig. 3 is a transverse section on the line 3-8 of Fig. 1,

Figs. 4 and 5 are perspective views of the overlapping portions of the rails.

The body portions of the rails near the ends are represented at 10 and 11 and include the usual flange, web, and ball or head.

The portions of the rails at the ends are reversely scarfed or bevelled as repre sented at 12 and 1.3, with the bevelled portions overlapping as illustrated in 1 and 2, but without increasing the width of the ball portions of the rails. The uniform width of the ball and flange portions of the rails is thus retained,'while the scarfed portions of the web are slightly increased, as indicated in Figs. 2 and 3.

A longitudinally directed recess or socket 14: is formed in the rail member 10, while a similar recess or socket 15 is formed in the rail member 11. A laterally extending rib 16 is formed on the bevelled portion 12 of the railmember 10, while a similar rib 17 extends from the bevelled portion of the rail member 11, as shown in Figs. 4 and 5.

Serial No. 564,721.

The sockets and ribs are so arranged that when the scarfed or bevelled faces of the rails are disposed face to face, the rib 16 will enter the socket 15 and the rib 17 will enter the socket 14, as indicated in Fig. 2.

The ribs are shorter than the sockets in which they are seated, as shown in Fig. 2, to provide for theexpansion and contraction produced by changes in the temperature.

The web portions and the rib portions of the rails are transversely apertured to receive clamp bolts 18 whereby the rail ends are held from lateral displacement, the apertures for the bolts being elongated to permit expansion and contraction.

The improved device is simple in construc-- tion, can be manufactured without material increase in the normal cost of the rails, and firmly unites the rails so as to prevent both lateral and longitudinal displacement, at, the same time presenting a continuous rail so that there will be no jars at the points where the improved device is applied as the rolling stock passes over the rails.

The strength of the joint herein shown and described is greater than the ordinary butt end joint, as one rail portion lies above the other for a considerable distance, thus distributing the strain over a r latively large area. The interlocking ribs or lugs 16-17 also add materially to the strength and increase resistance to the deflecting force caused by the rolling stock.

Clamp or fish plates are dispensed with, thus simplifying the construction and materially reducing the expense.

By the arrangement shown, four clamp bolts are used in each rail end, which also materially strengthens and reinforces the joint and effectually prevents lateral displacement.

The preferrod embodiment of the inven-' tion is disclosed in the drawings and set forth in the specification, but it will be understood that modifications within the scope of the claimed invention may be made in the construction without departing from the principle of the invention or sacrificing any of its advantages.

Having thus described the invention, what is claimed as new, is

A railway joint comprising coacting rails overlapping at their contiguous ends and with the overlapping portions reversely bevelled the bevelle jl face of each mil having :1 laterally projecting tongue at the outer end unil a longitudinally directed recess All the in er end the confronting ends of the tongues and recesses being in spaced re1ation and the tongue of each rail adapted to respectively enter the recess of the other rail when the rails are united and. means For clamplng the overlappmg portlons oi: the
