SPEGIFICATION forming part of Letters Patent No. 747,037, dated December 15, 1903.

Application filed July 18, 1903. Serial No. 16 6,l12. (No model.)

To ctZZvwwm it may concern:

Beit known that I, RILEY C. BOTT, a citizen of the United States, residing at Grouse, in the county of Wallowa and State of Oregon, have invented new and useful Improvements in Rail-Joints, of which the following is a specication.

This invention relates to rail-joints, the object in view being to provide a simple, reliable, and effective joint for the meeting ends of the rails of a railway which will prevent the lateral or vertical bending of the rail ends at the point where the joints occur.

A further object of theinvention is to construct the splice-bars or fish-plates in such manner that they may be readily applied to and removed from the rails and interlock with the rails both at the head and base when in their applied positions.

With the above general objects in view the invention consists in the novel construction, combination, and arrangement of parts, as hereinafter fully described, illustrated, and claimed.

In the accompanying drawings, Figure 1 is a perspective View of a rail-joint constructed in accordance with the present invention. Fig. 2 is a vertical longitudinal section through one of the sh-plates or splice-bars.v Fig. 3 is a side elevation of two rail ends, showing the detachable key. Fig. 4 is a vertical crosssection through the rail-joint, taken in line with one of the bolts. Fig. 5 is a detail perspective view of the key.

Like reference-numerals designate corresponding parts in all the figures.

In carrying out the present invention I make use of a pair oi' fish-plates or splicebars, each of which is composed of two sections .l and 2, pivotally connected or hinged together aboutcentrally of their height. The upper and lower sections of each fish-plate or splice-bar are provided with interfitting knuckles 3, while all the knuckles are provided with longitudinally-extending and registering openings for the reception of a hingepin 4, which extends practically the entire length of the fish-plate, as shown in Fig. 2, and enables the two members of the sh-plate to be rocked relatively to each other.

The upper member l is provided along its upper edge with upstandingdowels orprojections 5, while the lower member is provided along its lower edge with downwardly-extending dowels or projections 6. The head of the rail is provided with'sockets or recesses 7 to receive the projections 5, and the base ofthe rail is provided with sockets or openings 8 to receive the projections 6, so that when the fish-plates are in position a positive inter- Iocked engagement is had between said fishplates and the head and base of the rail ends. Two of such fish-plates or splice-bars are employed and located at opposite sides of the rail, so as to bear against the web ofthe rail, and they are held in place by two or more bolts 9, which extendthrough the fish-plates and web of the rail and are arranged so as to dodge the hinge-pins 4, as shown in Fig. 2.

The meeting ends of the rails are recessed correspondingly to receive the opposite ends of a key l0, as shown in Figs. 3 and 4, said key comprising a parallel-sided central portion 11, the tapering end portions 12, and the disk-shaped extremities or heads 13. The rail ends are recessed to loosely receive the end portions of the key 10, which acts to prevent breaking down of the joint and .also prevents undue separation or moving'apart ot' the ends of the rail. The key is inserted in the plates before the fish-plates or splice-bars are applied, the latter preventing the displacement of the key when in position.

In order to remove the Iish-plates, the bolts are first extracted, and then by means ot' a suitable pry or lever applied midway the height of the fish-plates the latter are broken outward along the line of their hinged connection, thus withdrawing the dowels or projections from their sockets in the base and head of the rail and permitting the fish-plates to be entirely removed.

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

1. A rail-joint comprising a pair of lishplates, each composed of two members provided with-intertitting knuckles connected by a hinge-pin extending lengthwise of the members, bolts for securing the iish-plates to the rail ends, one or both of said members being provided with projections' which are ICO received in sockets in the rail ends, substanthe displacement of the key, substantially as tally as described. described. 1o 2. A rail-joint comprising rail ends having In testimony whereof I aix my signature the web portions thereof recessed, a key rein presence of two Witnesses.

5 movably tted in said recess and serving to RILEY C. BOTT.

prevent excessive endwise movement of the Witnesses: rails, and fish-plates'secured to the opposite LINCOLN AUSTIN,

sides of the rail ends and acting to prevent H. C. DEVINE.
