RAIL-JOINT.

SPECIFICATION forming part of Letters Patent N 0. 680,538, dated August 13, 1901.

Application filed January 2, 1901.

T0 at whom it may concern:

Be it known that I, WILLIAM J. MOORORY, a citizen of the United States, residing at Rochester,Beavercounty,Pennsylvania,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 en-' able others skilled in the art to which it appertains to make and use the same.

This invention relates to certain improvements in railroad-rail joints.

The object of the invention is to provide an exceedingly strong, effective, and durable joint for railroad-rails whereby the employment of nuts and bolts, and consequently nut-locks, can be dispensed with and which can be easily applied to the rails now in common use and when once properly applied will reduce to a minimum all danger of accidental displacement and looseness of parts.

The invention consists in certain novel features in construction and in combinations and in arrangements of parts, as more fully and particularlypointed out and specified hereinafter.

Referring to the accompanying drawings, which show for the purposes of explanation a construction as an example of a device within the spirit and scope of myinvention, Figure 1 is a cross-sectional view showing a rail with a joint constructed in accordance with my invention. Fig. 2 is a side elevation of the adjacent ends of two rails jointed together by the device of Fig. 1, the ties or sleepers being partially broken away. Fig. 3 is a top plan view of the construction shown in Fig. 2.

In the drawings, a a are railroadrails of the construction in general use.

b b are the usual sleepers or cross'ties on which the rails rest and to which they are secured.

c c are the angle-bars or angle fish-plates trance along the two railsin opposite directions from their meeting or adjacent extremities. Two angle-bars are employed at each joint on opposite sides of the rails, as usual, and bridging the break between the rails. The two angle-bars of each joint are similar in construction, and each has the vertical flange extending from the foot of the rail to the un- Serial No. 41,897. (No model.)

der side of the head thereof and the bottom flange resting on the foot of the rail and usually projecting outwardly beyond a side edge of the foot. The top edge of the vertical flange of each angle-bar is preferably (al though not necessarily) formed with a head 0', formed to conform to the shape of the under surface of the head or tread of the rail and have an extensive bearing-surface there- 'against, and thereby tend to brace and support the rail against lateral strain and pressure. of the angle-bar is formed to conform to the angle and formation of the top face of one side of the foot of the rail, so that the under face of each angle-bar approximately through- The formation of the rails and angle-bars is usually such that the angle-bars can be insertedlaterally between the heads and feet of the rails and fit therein approximately as shown in Fig. 1 of the drawings.

Clamping and locking means are provided at both ends of the angle-bars to force the bars up against the rail-heads and to force them inwardly toward the rail-webs or vertical portions, and thereby lock and wedge the angle-bars inwardly against the inclined faces of the rail feet and heads. Various devices and arrangements can be employed for accomplishing these results within the spirit and scope of my invent-ion and Without the employment of the bolts and nuts. In the specific construction shown in the drawings I employ two tie bars or plates at (1, arranged at opposite ends of the joint and preferably similar in construction. Each bar or plate at is formed to pass transversely beneath a rail and rest longitudinally on a sleeper or tie and at its projecting ends, beyond the railfeet, an gle-bars, and clamps, is provided with transverse openings d, through which spikes The under face of the bottom fian'ge out its full length and width engages and rests walls d d of said seat abut against the outer ports firmly lock the tie-plates against move ment in any direction. The ends of the tieplate beyond the side edges of the rail-feet are enlarged upwardly to form clamping or gripping jaws d of great strength and rigidity. Thesejaws are peculiarly formed .to grip and-interlock with the projecting end edges of the angle-bars. In the specific example shown in the drawings the inner vertical face of each jaw is formed with a transverse (usually V- shaped) groove, which receives the correspondingly-formed edge of the anglebar. This groove is inclined or tapered transversely,'and the edge of the angle-bar is correspondingly inclined or tapered. I prefer to form the transverse groove and the corresponding edge portion of the angle-bar of fiat abutting faces. The under face 2 of the tie-plate, which is transversely inclined upwardly and outwardly from the foot of the rail, and the corresponding approximately parallel abutting face 2' of the angle-bar edge are arranged in planes intersecting about at right anglesthe linesof lateral strain on the rails. The opposite or upper face 3 of the groove in the clamp or tie-plate and its corresponding approximately parallel abutting face 3 of the angle-bar are both shown about at right angles to the faces 2 2, although, as at present advised, I do not wish to so limit my invention.

Each tie-plate in effect forms a clamp abutting against the corresponding end portions of the angle-bars. The inclined abutting faces of each clamp are oppositely arranged, so that as said clamp is forced longitudinally of the angle-bars in a direction awayfrom the adjacent extremities thereof said bars will be both forced inwardlyof the rail and rigidlylocked. The clamp at the opposite ends of the anglebar moves in the opposite direction to lock the bars and rail together at that end of the joint. It will hence be observed that it is only necessary to provide the end portions of the angle-bars with the longitudinally-inclined wedging-faces 2 3'. I preferably form the under abutting faces 2 2 with an inclinalion-or taper less than that of the faces 3 3, so that when the parts have been assembled and a clamp is driven onto the ends of the angle-bars the faces 2 2 at opposite ends thereof will tend to slightly elevate the lower will wedge and force the angle-bars inwardly into the space between the heads and feet of the rail and force said bars down tothe feet with great pressure and form and constitute a most positive and rigid lock which cannot work loose.

The joint by reason of its formation and rigid construction cannot spread, and by reason of the opposite tapers at opposite ends of the anglebars the joint cannot creep longitudinally of the rail, as a tendency to such movement will cause tightening of the joint.

The clamps and angle-bars can be placed in position or removed without removing either the sleepers or rails, and yet when the clamps have been locked in position and spiked they are rigidly held by the wedging-faces and also by the spikes, which immovably lock the entire structure.

While I attain great strength and material advantages by employing the two faces at each end of a clamp and angle-bar and by locking said faces at the outer edge of the angle-bars, yet I do not,,as at present advised, desire to so limit my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-
