Application iiled April l. 1907. Serial No. 365.752.

To all whom it may concern:

Be it known that I, MICHAEL BRAKE, a citizen of the United States, residing at Cora, in the county of' Latah and State of Idaho, have invented certain new and useful Improvements in Railroad-Joints, and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in railway rail joints, particularly with reference to the construction of the meeting ends of the rails, so that the same are adapted to be secured together without the use of theA chairs or other devices ordinarily employed at the joints oi such rails, and it consists in the construction, combination and arrangement of devices, hereinafter described and claimed.

In the accompanying drawings,-Figure l is a perspective view of a railway rail joint embodying my invention; Fig. 2 is a longitudinal sectional View of the same; Fig. 3 is a horizontal sectional view of the same, on the plane indicated by the line a-a of Fig. 2; and Fig. 4 is a vertical transverse sectional view of the same, on the plane indicated by the line b-b of Fig. 2.

For the purposes of this specification, the meeting ends of the rails are here indicated at 1, 2. The rail end 1 has a tongue 3 extending longitudinally from its head and forming recesses 4 on opposite sides of said tongue. A recess 5 is formed in said rail end under the inner portion of the said tongue. Said rail end is thickened on opposite sides to form lateral extensions* G, the outer sides of which are flush with the sides of the rail head, and the said extensions form the side walls oi the recess 5. The rail base 7 is cut away to form a recess 8 under the projecting end portions oi the said extensions 6. In the face of the recessed base is a recess 9. A recess 10 is formed in the under side of the tongue 3 and has a rentrant shoulder 11 at its lower outer corner.

The rail end 2 has a tongue l2 projecting from its base to enter the recess 9 of said rail end 1. The reinforce extensions 13 of said rail end 2, which are otherwise similar to those of the rail end l, are recessed at their ends, as at 14, to receive the projecting end portions of the reinforce extensions G. In the head of the rail end 2 is recess l5, the upper side of which is open. Said recess is to receive the tongue 3 of the rail end 1. The bottom of said recess is coincident with the upper side of a tongue 16, which lies in the angle between the base of said rail end and the recessed ends 14 of the reinforce extensions 13, and from the upper side of the said tongue extends a vertical hook 18 to l enter the recess 10 ofthe tongue 3 and engage the shoulder 11 thereof. The length of the said recess exceeds that of the said tongue, so that said rails may move longitudinally to a slight extent with respect to each other, to enable them to be connected and disconnected, and also to compensate for expansion and contraction.

It will be understood that the tongue 12 and hook 18 of the rail end 1, by engagement respectively/with the recesses 9 and 10 of the rail end 1, prevent said end from rising independently of the rail end 2, that the tongue 3, and extensions 6 of the said rail end 1, which bear on the rail end 2 prevent said rail end 2 from rising independently of the rail end 1; that said reinforce extensions 6, 13, of the rail ends, together with the coengaging tongue and recesses, between said extensions, prevent either of said ends from moving laterally independently of the other, so that the rails cannot spread, and that said tongues 3, 16, and extensions 6,13, coact to form a lap joint between said rail ends, so that the weight of a train in passing over said joint is distributed between the rails and neither of the ends thereof can rise or fall and the heads of the rails present an unbroken surface at the joints, for the treads ofthe wheels to roll upon. The usual notches 19 are provided in the base flanges of the rails, for the reception of spikes, such as are usually employed to secure the rails on the cross ties.

From the foregoing description, taken in connection with the accompanying drawings, the construction and without requiring a more extended explanation.

Various changes in the form,` proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention, as defined by the appended claims.

Having described my invention, I claimi- A rail joint comprisinga pair of rails, one of which is provided at its meeting ends with a recess in the tread thereof and with its sides cut away to form a tongue, and a verticallyextendng hook carried by said tongue, and the meeting end of the other rail having a longitudinallyextending' tongue formed at the tread thereof to fit in the recess in the tread of the other rail, said tongue having a shouldered recess in its lower face to lit over and engage the vertical hook of the other rail and side ianges engaging the opposite sides of the tongue of the rst-mentioned rail.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

MICHAEL BRAKE.
