RAIL-JOINT.

Specification of Letters Patent.

Patented Aug. 11, 1914.

Application filed July 25, 1913. Serial No. 781,221.

To all whom it may concern:

Be it known that I, ELVIS L. BARNES,

citizen of the United States, residing at 110- bart, in the county of Kiowa and State of ()klahoma have invented certain new and useful Improvements in Bail- Joints, of which the following is a specification.

This invention relates to improvements in railway rail joints, and has for one of its objects to improve the construction and increase the strength and utility of devices of this character.

Another object of the invention is to provide a simply constructed joint which produces a continuous rail whereby deflection is prevented at the joints, and the rail is rendered as stiff and strong at the joints as at the other portions.

With these and other objects in view the invention consists in certain novel features of construction as hereinafter shown and de scribed and then specifically pointed out in the claim, and in the drawings illustrative of the preferred embodiment of the invention. Figure 1 is a side elevation of the confronting ends of a pair of rails, illustrating the improved joint. Fig. 2 is a plan view of the parts shown in Fig. 1. Fig. 3 is a transverse section on the line 33 of Fig. 1. Figs. 4 and 5 are perspective vi ws of the confronting rail ends illustrating their construction. Fig. 6 is a perspective view of the intermediate member of the joint with the central portion broken away.

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

The body portions of the rails are of the usual construction and comprise the base or flange portion 10 the web portion 11 and the ball or tread portion 12. At their ends the tread portions and the web portions are extended beyond the flange portion and the extended portion of the web is thickened as represented at 13, the thickened portion extending for a short distance rearwardly of the flange 10. The vertical distance of the extended portion 13 of the web and tread is less than the total vertical distance of the rail, as shown in Figs. 4 and 5.

The confronting portions of the extended webs and treads overlap and the overlapped portions are reduced transversely obliquely to the longitudinal plane of the rail whereby oblique bearing faces l t-+15 are produced and with stop shoulders 16 at the inner ends of the overlapped portions. By this arrangement when the rails are disposed end to end and in longitudinal alinement a space is left between the flange portions 10 of the rails, and fitting within this gap is a combined bridging and bearing plate 17 which engages at its ends against the ends of the flanges 10 and bears by its upper face beneath the projecting portions 13. Rising from the base 17 are clamp members 18-l9 which engage against the thickened portions 13 of the rails and project at their ends beyond the base 17 and against the inner parts of the thickened portion 13. The portions 13 of the rails are apertured transversely, as shown at 20, while the members 18-19 are provided with similar apertures 21 which register with the apertures 20 when the parts are assembled, the registering apertures being designed to receive clamp bolts 22, the latter being pro vided with the usual clamp nuts 28. The apertures 20 are slightly elongated to provide for the necessary contraction and expansion of the joint.

It will be noted that the clamp members 1819 are extended at their ends beyond the brace member 17 and bear by the extended portions upon the upper faces of the flanges 10, the portions of the flanges upon which the ends of the members 1819 bear being flattened to form seats as represented at 2 1, to receive the downward pressure of the plates.

By this simple means it will be obvious that a simply constructed joint is produced which firmly supports and holds the confronting ends of the rails and effectually prevents all sagging or downward displacement, and renders the joint portion of the rail as strong as other portions, thereby producing an effectual continuous rail which prevents all uneven movement of the rolling stock, and likewise prevents all sagging or displacement under hammer blows of the locomotive and other rolling stock.

By the arrangement of the parts shown, it will be noted that a relatively lon bearing face is produced which effectual y protects the rails and prevents deflection and distributes the strains over a correspondingly large area.

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

Railway rails having the head and web portions extending in advance of the flanges ing through said rail members and the porand with lateral seats upon the upper faces tions of the rails between them. 10 of the flanges, a base member bearing be- In testimony whereof I aflix my signature neath the extended portion of the Webs, in presence of two witnesses.
