RAIL-JOINT.

SPECIFICATION forming part of Letters Patent No. 787,615, dated April 18, 1905.

Application filed July 2, 1904. Serial No. 215,148.

To all whom it may concern.-

Be it known that we, JOHN EDWARDS, of Homestead, and JOHN JARRETT, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a certain new and useful Improvement in Railway-Joints, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure 1 is a plan view, partly in section, showing our invention. Fig. 2 is a vertical sectional view of the same. Fig. 3 is aplan view, partially in section, showing a modification; and Fig. 4 is a vertical sectional view of the same.

Like symbols of reference indicate like parts wherever they occur.

Our invention relates to an improvement in fish-plates for securing the rails to each other and also for securing the rail to the chair and it consists in a fish-plate made in two parts and adapted to exert a binding force between the rail and the chair when pressure is applied to the rail in such a manner that the rails shall be securely held to each other and to the chair.

I/Ve will now describe our invention, so that others skilled in the art may manufacture and use the same.

In the drawings, 2 represents the rail,which may be of the ordinary form, and 3 the chair for supporting the rail, which chair is provided with a seat 4, adapted to receive the flange of the rail. The fish-plate is composed of two parts-the bar or plate 5 and a base portion 6, which base is provided with a curved seat 7 in its upper face adapted to receive the curved lower portion of the plate 5. The upper edge of the plate 5 is adapted to rest beneath the head of the rail 2. The baseplate 6 is provided with a laterally-extending portion or flange 8, which is adapted to fit within a seat 9 in the chair 3. This seat is formed at the same angle as the upper face of the base of the rail.

In Figs. 3 and 4 the plate 6 is of somewhat different shape than the plate shown in Figs. 1 and 2, and a liner 10 is placed between the edge of the plate 6 and seat 9 of the chair 3. In this modification the base-plate "6 is secured to the chair by means of the spike 11, which is driven through an enlarged opening in the base-plate, the rail, and the chair, passing through these openings down into the tie 12, thus holding the base-plate 6 in position, and yet allowing it a certain range of movement laterally and longitudinally.

The operation is as follows: In laying the track the chair 3 is first bolted to the ties, the rail 2 is placed within the seat 4 of the chair, the flange or extensions of the fish-bar is placed within the seat 9 of the chair 3, and the vertical portion 5 of the fish-bar is driven into place lengthwise, with its lower portion in the seat 7 and its upper portion resting under the head of the rail, thus acting as akey to hold the parts together. The fish-plates on opposite sides of the rail are thus secured against the rail and without danger of coming apart.

In the modification shown in Figs. 3 and 4 the lower portion 6 of the fish-plate is spiked through the chair 3 to the tie 12, the spike 11 serving not only to hold the base of the fishplate in position, but also to secure the chair to the tie, and between the fish-plate 6 and the seat 9 of the chair is placed the liner 10.

In operation the pressure of the train on the head of the rail 2 is exerted on the portions 5 and 6 of the fish-plate, the seat 7 giving a pivotal connection between these parts, and the base 6 of the fish-bar is forced more firmly in the recess or seat 9 of the chair 3, thus causing a more perfect joint between the rail and the chair and between the several rails at the time the train passes over the same, practically forming a continuous rail.

Any suitable stopper may be used, if necessary, to prevent the plate 5 and rail 2 from creeping.

The advantages of our invention will be appreciated by those skilled in the art, as it affords a firm, secure, and durable railjoint which effectually lessens the jar and movement of the train and at the same time is not liable to become loose or disjointed.

Having thus described our invention,what

we claim, and desire to secure by Letters Patent, is I 1. In a rail-joint, the combination of a chair and a two-part fish-bar, the lower portion of the fish-bar being adapted to be seated in the chair, and being provided with a seat for the upper portion of the fish-bar, the upper portion of the fish-bar being adapted to be driven between the head of the rail and the lower portion of the fish-bar; substantially as specified.

'2. In a rail joint, the combination of a chair having a seat for the reception of the lower portion of the fish-bar, a seat formed in the lower portion of the fish-bar, and a bar adapted to be driven between this seat and if'Jihei head of the rail; substantially as speci- 3, In a rail-joint, the combination of a chair having a seat for the reception of the rail, and a seat for the reception of the flange of the fish-bar, the angle of the base of this seat corresponding with the angle of the up per face of the base of the rail, and a twoi part fish-bar, the flange of the lower portion being adapted to fit in the seat of the chair, and the upper portion being adapted to be driven between the head of the rail and the lower portion of the fish bar; substantially as specified. v

* 4. In a rail-joint, the combination of a chair having a seat for the reception of the lower portion of a fish-bar, and a two-part our hands.
