RAILROAD-RAIL JOINT.

SPECIFICATION forming part of Letters Paar No. 612,059, dated October 11, 1898. Application filed September 4, 1897: Serial No. 650,626. (No model.)

To all whom it may concern.-

Be it known that LJOHN ROHLIN, a citizen of the United States, residing at Eureka, in the county of Greenwood and State of Kansas, have invented a new and useful Railroad-Rail Joint, of which the following is a specification.

This invention relates to railroad-rail joints, its object being to provide a simple device of this character of improved construction which may be applied to rails now in use and which will alford a strong and secure support and connection for the meeting ends of the rails and prevent the ends of the rails from being battered or mashed by the wheels and also largely decrease the rattling and noise caused by the wheels in passing over the joints.

With this and other objects in View the invention consists of the several details of con-' struction and combination of parts, as will be hereinafter fully described, and particularly pointed out in the claims. 1

In the drawings, Figure 1 is a side elevation of a rail-joint constructed in accordance with my invention, looking at the outer side of the rail. Fig. 2 is a similar view looking at the inner side. Fig. 3 is a plan view. Fig. 4 is a vertical transverse section on the line at a: of Fig. 3. Fig. 5 is a similar view on the line y y of Fig. 3. nal section of the base-plate.

Similar reference-nu merals indicate similar parts in the several figures.

The rails are indicated by 1 and the baseplate by 2. The base-plate is provided with a rib or flange 3 at each of its side edges, extending throughout its length, and also with shallow grooves 4 in its upper face at each side adjacent to the ribs in order to form a raised central portion 5 of a width substantially equal to that of the base of the rails.

The grooves 4 are intended to receive a portion of the horizontal member of the fish-plates, and the ribs 3 will form abutments for the edges of the horizontal members of the fishplates. In its normal condition the base-plate is preferably convex on its upper face, as shown in Fig. 6, and this convexity may be made either by bending the plate or by gradually decreasing its thickness from'the middle to each end. The plate is also thickened or reinforced on its lower surface at its middle Fig. 6 is a vertical longitudiportion, as indicated at 6. The object of makin g the upper face convex and reinforcing the plate at its middle portion is to strengthen the plate immediately below the meeting ends of the rails in order to overcome any tendency of the rails to bend downwardly at their ends. 7 indicates the fish-plate or angle-bar for the inner sides of the rails, and S the fishplate for the outer sides. The fish-plate 7 is of the ordinary construction, with its vertical member fitting in between the head and flange of the rail to abut against the web thereof and its horizontal member being supported on the rail and also in the shallow groove 4 on the inner side of the'base-plate. The horizontal member of the fish-plate 8 also rests upon the flange of the rail and in the groove 4 on the outer portion of the base-plate, and its vertical member fits between the head and the flange of the rail and engages the web thereof in the ordinary manner. This fishplate is, however, provided with an upward extension 9, which will be termed a bridge, and extends from end to end of the fish-plate. The middle portion of this bridge is designed to be flush with or slightly above the top surface of the rails where they meet, and it inclines downwardly from the middle portion toward each end in order to bring its ends below the top surface of the rails, so that they will not be engaged by the wheels when they pass over the rails. The bridge 9 and vertical member of the fish-plate 8 are also reinforced or thickened laterally at their middle portions, as indicated at 11.

12 indicates the horizontal bolts which secure the two fish-plates together and to the rails, and 13 the nuts which securethese bolts in place.

14 indicates the vertical bolts which secure the horizontal members of the fish-plates to the base plate, and 15 indicates the nuts which secure these bolts in position. The outer edge of the base-plate is provided with a notch at each end for the reception of a spike, by means of which the plate will be secured on this side to adjacent cross-ties.

17 indicates a locking-plate for the nuts 13 and the nuts 15 on the outer side of the rails. This plate is supported upon the horizontal member of the fish-plate S and is provided with elongated openings 18 for the passage of the bolts 14:.

19 indicates lateral extensions from the inner edge of the plate 17, and these extensions are folded over upon themselves and bent upwardly in order to project below and engage the nuts 13. The object of folding these projections upon themselves is to stiffen them and permit the use of thin metal for the locking-plate.

21 indicates lateral extensions on the outer edge of the plate 17, and these extensions are bent upwardly at a right angle and are intended to engage the nuts 15 and lock them against turning on the bolts 14. One end of the plate 17 is bent downwardly, as indicated at 22, in order to engage the end of the fishplate 8, and the elongated openings are so arranged that when this downwardly-bent end 22 is in engagement with the end of the fish-plate the bolts 14 will be at one end of the elongated openings 18, which latter will extend toward the downturned end 22. It will be seen, therefore, that when in this position the plate 17 will be incapable of longitudinal movement in either direction, and the projections 19 and 21 will be in engagement with their respective nuts, and the latter will consequently be locked against turning. In order to release the nuts, the downwardlybent end of the plate 17 must be elevated sufficiently to disengage it from the end of the fish-plate, and it can then be moved longitudinally to disengage the projections 19 from the nuts 13,'it being of course understood that the extensions 21 will be bent down to disengage them from the nuts 15 and that the latter will have to be loosened to permit the plate to move freely.

23 indicates a locking-plate for the nuts 15 on the inner side of the rails, and this plate is provided with perforations for the passage of the bolts 14 and with lateral extensions 24, which are adapted to be bent up at a right angle to engage the nuts 15. The plate is also provided with notches 25, which register with openings 26 in the horizontal member of the fish-plate 7, and these notches and openings are for the passage of spikes or similar devices to secure the base-plate to adjacent ties.

In operation the two fish-plates will be bolted to the rails in the ordinary manner, and the base-plate will then be inserted in position below the rails and the fish-plates and secured to the horizontal member of the fishplate 7, the locking-plate 23 being alsosecured in position at the same time. The extensions 24: will then be bent up to engage the nuts 15 and the parts will be firmly secured together on the inner side of the rails. The locking-plate 17 will then be placed in position, with the projections 19 in engagement with the nuts 13, and the bolts 14: will then be passed up through the registering openings in the base-plate and the horizontal member of the fish-plate 8 and secured in position plate will be forced up into contact with the rails and the central portion 5 of the plate will be in engagement from end to end with the rails, and the middle portion of the baseplate will thus be given a tendency to spring upward, and therefore form an elastic as well as averystrong support for the meeting ends of the rails.

From the foregoing description it will be seen that I have produced an exceedingly simple, strong, and secure joint which will prevent the meeting ends of the rails from sagging downwardly and will also prevent the wheels from battering or mashing the ends of the rails and also will largely decrease, if not entirely overcome, the rattle and noise caused by the wheels passing over the joints.

\Vhile I have illustrated and described the base-plate as having its upper face normally convex in longitudinal section and this is the preferred shape for the purpose of giving elasticity to the joint, certain features of my inventionto wit, the reinforcing or thickening of the base-plate on its lower surface at its middle portion, the raised central portion of the base-plate, on whichthe rails are supported, and the ribs on the edges thereof may be employed with equal advantage on base-plates having a normally straight upper face, and hence I do not intend to limit my invention in all its details to a base-plate having an upper face normally convex in longitudinal section.

It will be understood that changes in the form, proportion, and the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.
