Application led may 21, 1913. .Serial No. 769,026.

To aZZ whom 'it may concern:

Be it known that l, JAMES C. Roer, a citizen of the United States, residing at Gretchell, in the county of Snohomish and State of Washington, have invented new and useful Improvements in Rail-Joints, of which the following is a specification.

The present invention relates to rail oints, and has for its primary object to provide a safe and efficient connection between the meeting ends of railroad rails, and which will at the same time avoid the jar incident to the passage of the wheels of the rolling Stock over the joint.

Another object bf the invention is to construct a rail joint which will provide an unbroken tread without weakening the rails or the means for fastening the meeting ends of the rails together.

A still further object of the invention is the construction of a rail joint wherein the meeting ends of the rails are at all times and under all conditions engaged throughout their entire lengths by joint members which not only prevent the lateral movement of the rails, but which effectively prevent the sinking of the rail ends or an upward projection of either of the rail ends.

l/Vith the above recited objects in view, and others which will appear as the nature of 'the invention is more fully understood, the improvement resides in the construction, combination and arrangement of parts set forth in the following specification and falling within the scope of the appended claim.

ln the drawings: Figure l is a side elevation of a rail joint constructed in accordance with the present invention, Fig. 2 is a top plan view of the same, Fig. 3 is a sectional view on the line 3-3 of Fig. 2, Fig. i is a sectional View on the line 4-4 of Fig. 2, Fig. 5 is a sectional view on the line 5 5 of Fig. 2, Fig. 6 is a perspective view of the rail ends, Fig. 7 is a similar view of the fish plates, and Fig. 8 is a similar view of the base plate or chair.

, Referring now to the drawings in detail, R-R designate two co-acting rails. Each of these rails is of the ordinary construction, but each of said rails has its head seal/- loped at a suitable distance from its end at its head, as indicated by the numeral 1. The Scalloped heads of the rails each have an inwardly curved wall which has its lower portion provided with a rounded edge, as

indicated by the numeral 2. rll`he walls l are not vertically straight throughout their entire length, but the walls are inclined from their lower portions upwardly and outwardly.

The numerals 6 designate the angle splice bars of the joint. These splice bars have their inner faces shaped to engage the webs and base flanges of the rails and beneath the balls or heads of the rails. Eachv of the splice bars ti is centrally provided with a vertically extending crest 7, the same projecting above the upper horizontal edges of the bars proper a distance equal to the thickness of the heads of the rails. The crests 7 have their inner walls curved or elliptical in plan, and the said inner faces of the crests are spaced a suitable distance away from the upper longitudinal edges of the said angle bars proper to provide a continuous bearing surface which may be designated by the numeral 8. rlhe central inner faces of the crests are inclined upwardly and outwardly from the shoulder S, as indicated by the numeral 9 to agree with the ends of the rails so that the walls of the opposite splice bars and the heads of the rails provide a substantial butt connection at this point of the joint. The rounded inner face of each of the crests 7, is shaped to agree with the formation of the heads of the rails at the said point, and the said faces of the crests at the section 3 3 are likewise shaped to correspond with the Ifaces of the heads at this point. it will thus be noted that the scalloped or concaved faces of the heads of the rails at the ends of said rails have both their upper and lower portions, including their walls, at all times vengaged by the inner walls of the crests of the splice bars when the said splice bars are associated with the rails, regardless of the longitudinal movement of the rails incident to the expansion or contraction of the said rails or of the splice bars for the rails. The splice bars and the webs of the rails are provided with a plurality of spaced registering openings for the reception of securing elements in the nature of nuts and bolts.

lli/while not essential, l have found it desiralole to provide the joint with a base plate or chair. rlhe chair C has its upper face horizontally straight, andits longitudinal edges ianged, as at C. The outer longitudinal edges of the plate are provided with a plurality of depressions C for the reception of securing spikes, the heads of which also overlie the base portions of the angle bars 6. The underface of the plate C is channeled throughout its entire 4length at spaced intervals, as indicated by C".

From the above description, taken in connection with the accompanying drawings, the simplicity of the device, as well as the ad vantages thereof, will, it is thought be perfectly apparent to those skilled in the art to which such inventions appertain without further detail description.

Having thus described the i'nvention, what I claim is: l

In combination, two abutting rails,`said rails having the heads tapered to form a recess at each side ofthe rails, said heads being formed with upwardly and outwardly inclined faces, two splice members having surfaces adapted to fit snugly in said recesses, said splice members having inclined sides to conform to the inclined faces of said rail heads, the top of said rail heads and splice members being convex transversely, means for holding said splice members against said rails,lateral ribs formed upon said splice members and arranged to it under the heads of said rails, and flanges formed upon said splice members and en. gaging the base ianges of said rails.

In testimony whereof I aflix my signature in presence of two witnesses.

JAMES C. ROOT.
