RAIL-JOINT.

Specification of Letters Patent.

Patented Mar. 26, 1912.

Application filed October 8, 1908. Serial No. 456,734.

To all whom it may concern:

Be it known that I, JOHN P. DULLUM, a citizen of the United States, residing at Wright, in the county of Carlton, State of Minnesota, have invented certain new and useful Improvements in Rail-Joints; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artl to which it appertains to make and use the same.

The invention relates to a rail joint and more particularly to the class of angle bars or fish plates for uniting the meeting ends of railway rails to each other.

The primary object of the invention is the provision of a rail joint comprising a pair of angle bars disposed at opposite sides of the meeting ends of railway rails, the said bars being coupled or united thereto by bolt fasteners passing through the same and the webs of the rails, one of said angle bars formed with a thickened portion containing a longitudinal seat to accommodate the treads of the meeting ends of the railway rails to prevent the sinking of the latter at their abutting extremities and also to strengthen the said treads and prevent lon` gitudinal vertical splitting thereof caused by heavily loaded cars traveling upon the track rail.

train the wheels will be thrown in such position as to prevent the shearing of the clamping bolts.

In the drawings accompanying and forming part of this specification is illustrated the preferred form of embodiment of the invention which to enable those skilled in the art to practice the invention will be set forth at length in the following description while the novelty of the invention will be included in the claim succeeding said description.

In the drawings z-Figure 1 is a side elevation of the meeting ends of two railway rails with the invention applied thereto. Fig. 2 is a reverse side elevation of the same. Fig. 3 is a transverse sectional view on the line 2-2 of Fig. l. Fig. 4L is a top plan view.

Similar reference characters indicate corresponding parts throughout the several .Views in the drawings.

In the drawings the numeral 5 designates the meeting or abutting ends of two railway rails, each comprising a base 6, vertical web 7 and a tread or head 8, which rails are of the ordinary construction. At opposite sides of the rails 5 and bearing against the webs 7 thereof laterally and overlapping the two rails for some distance from the abutting ends are angle bars or fish plates S) and 10, the latter' of which is formed with a thickened wall orportion 11, the same containing in its top face near its inner edge a longitudinally disposed recess formmg a seat l2, to accommodate and receive the outward laterally projecting portion of the tread or head 8 of the two rails so as to reinforce and strengthen the treads or heads of the rails at the abutting or meeting ends thereof.

The angle bar 9 is formed with a vertical portion 13 having a fiat upper edge and the same adapted to tit snugly between the treads or heads 8 and the bases (i of the meeting ends of the rails 5 so as to coact with the thickened portion 11 underlying the treads or heads S of the said rails to prevent the lowering or sinking of either abutting end of the two rails. Passing through openings contained in the anole bars 9 and 10 and through registering ho es in the web 7 of the rails are bolt fasteners 14 so as to connect t-he said angle bars for joining the abutting or meeting ends of the railway rails.

It is obvious that the thickened portion l1 of the angle bar 10 having the longitudinal recess or seat 1Q receiving the laterally projecting outside portion of the treads or heads S of the two rails 5 serves to reinforce and strengthen the treads or heads of the meeting ends of the rails at a point directly opposite where the flange of a car wheel engages'the laterally inwardly projecting portion of the said treads or heads of the rails, so as to prevent the splitting or spreading of the treads or heads 8 of the meeting ends of the rail during the travel of heavily loaded cars upon the track rails.

It will be readily seen from an inspection of the drawings that the reinforcement l1 of the angle bar 10 is beveled at its upper edge and at both ends. This construction serves for the purpose of deflecting the wheels of a train upon derailment from contact with the bolts 14 which prevents the shearing of the ends thereof.

lVhat is claimed is In a rail joint, the combination with the meeting ends of two rail sections; of angle bars fitted upon the inner and outer faces of said rails and overlying their connection, the inner angle bar having an inwardly beveled upper port-ion upon which the heads of the rails are Supported and a concaved portion outwardly thereof and extending from the inner face of the head to a point therebelow, the outer angle bar having a central enlargement provided with a rectilinear outer face and with side portions tapering inwardly toward the ends of the loarthe top portion of the bar being provided with a narrow horizontal tread ysurface and a beveled surface outwardly thereof to provide inclined end portions, the upper inner edge of the outer bar being formed with a shoulder receiving the under and outer portion of the head of each rail in supporting position and fastening bolts connect-ing the parts within the area of the rectilinear portion of the enlargement, the face of the inner bar having semi-circular depressions in an enlargement below the bolt heads.

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

JOHN P. DULLUM.
