RAIL-JOINT.

SPECIFICATION nrniing part of Letters Patent No. 484,227, dated October 11, 1892. Application filed october 27,1391. serian. 409,950. (remodel.)

,T0 allez/710111. it vWtay concern: p Be it known that I, MILTON O.N1LEs, a citi! ing the downward springing or bending of' theirendsespecially where such ends come between two cross-ties, and at other points where there is no iirm supportbeneath them.

The prime object of my invention is to provide a rail-joint which sh all possess the maximulln strength with a given weight of materla A further object of my invention is to obviate the weakening of the rails caused by the formation of holes through the webs thereof for the passage of bolts, and at the same time to equalize the movement caused by the expansion and contraction of the rails.

With these ends in View my invention consists in certain features of noveltyin the construction, combination, and arrangement of parts by which the said objects and certain other objects hereinafter described are .accomplished, as fully explained, with reference to the accompanying drawings, and more particularly pointed out in the claims.

In the said drawings, Figurel is a side elevation of the meeting ends of two railway-rails having my improved joint applied thereto. Fig. 2 isatransverse sectionalview thereof on a larger scale, taken on the line 2 2,Fig. 1. Fig. 3 is a perspective view of portions of the bottoms of the meeting ends of the rails, showing the manner of connecting thereto the abutment-plates, hereinafter described. Fig. 4 is a view similar` to Fig. 2, showing the joint as adapted for use where the rails are supported upon metallic bearing-plates; and Fig. 5 is a sectionalview partly broken away, illustrating a modification of the form shown in Fig. It.

In the drawings, wherein like signs of reference refer to like partsthroughout the several views, A indicates the rails, which are supported upon the cross-ties B in any wellknown and usual manner, and which rails are of the ordinary construction, with the exception that at their ends or other points where it'is desired to provide`them with one of my improved joints the foot-flange C of each is provided on both sides of the web with a number of socket-s or perforations c, in which lit, respectively, a corresponding number of lugs d, formed on or otherwise secured to and depending from the under side of overlying 6o abutment-plates D. The plates D are arranged on either side of the web, uponthe top of the foot-ange, and are provided along their outer edges with upright abutment- [langes d. The lugs (l, as shown in Fig. 4, are arranged at intervals throughout the length of the abutment-plates and are suited in number and size to the degree of strain brought against the abutment-plates by the pressure on the rail through the medium of 7o the members which are presently to be explained.

As more clearly shown in Figs. 2 and et, upon each of the horizontal surfaces cl3 of these abutment-plates D abuts the lower end or .edge of a brace or supporting plate E, whose upper edge or end abuts against the under side of the rail-head in the corner or angle I formed by the junction of the head with the web; or, if desired, it may impinge the head 8o or the web at any other point above the level of the abutment-plates, the construction and arrangement shown being preferred, however, for the sake of greater simplicity and strength.

The brace-plates E are designed to support the heads of the rails and prevent any downward-bending movement thereof under the pressure of the passing train, and to this end the said plates are of sufficient length to bridge the point of juncture between the ends of the 9o rails and extend a considerable distance along each rail, as shown in Fig. l. The braceplates are of greater vertical or upright eX- tent than the dist-ance between the abutmentplates and the under side of the rail-head or other points provided for the abutment of the upper edgesof such brace-plates, so that in placing the brace-plates between the rail-head and the abutment-plates it is necessary to inoline them outwardly or `diverge their lower roo ends, as shown, in such a manner that pressure applied to them between their lower ends and the abutment-flanges d will cause such brace-plates to wedge tightly between the rail- 2 i' seater head and the abutment-plates D, thus affording a firm support for thenreeting ends of the rails and at the same time holding the abutment-plates ti rmly against the foot-flange with their engaging-lugs d in place. Thisin- Ward pressure against the brace-plates may be supplied by means of any suitable wedging devices co-operating with the abutmentflanges d. As a convenient and preferable form of device for this purpose I have shown the abutment-flanges provided with short set screws or bolts F, arranged laterally-in the abutment-flanges and adapted to impinge the lower edges of the brace plates in a transverse direction for forcing their-said lower edges along the horizontal bearing-surfaces d3 toward the rails, and thus tightening the joint in the manner described. These set-bolts are preferably located as near to the lower portions of the abutment-platesD as possible, so as to cause the strain produced against the flanges d to be brought as far as practicable transversely -of the lugs nl and at the same time lessen the strain at the base of the flanges d.

In the drawings I have represented -eacli of the abutment flanges as being provided with four of these set-bolts disposed in a manner most advantageous for resisting the strain to which the brace-plates might be subjected, preferably one near each end and on-e on either side of and in close proximity to the `junction ,of the rails; but it will, of course, be understood that the number of these bolts and their disposition relative to each other and to the length of the brace-plates may be moditied at pleasure without departing from my invention.

The abutment-flanges d may be of any shape best adapted for strength in resisting the lateral thrust of the set-bolts and for reinforcing the lower portion of the abutmentplates D. A durable and economical form is that which I have shown, which consists of a flange having an increased depth at its midlength, where the greatest strain is felt. The lower edge of each of the brace-plates is preferably providedl with an enlargement or boss e,whose outer side is upright or vertical when in position, so as to afford a better bearingsurface for the ends of the set-bolts.

In order that the rails may come and go without damaging the joint in expanding and contracting under the influence of varying temperatures, I make the perforations cin the foot-flange of the rail of elongated form, as

shown in Fig. 3, and in order that the brace plates E may not be permitted to creep out of place from the same causes they may be provided with any suitable stops arranged-on any anchored or fixed portion, such yas the rail itself, the abutment-plates D, or even the crossy ties; but as a preferred manner of accomplishing this I provide the bosses e with countersinks or sockets G, in which the ends of the set-bolts F engage, and thus preclude longitudinal slipping of the plates E relatively to the lugs d down into them, as shown in Fig..

4,thus at the same timeincreasing thestrength of the lugs d and holding the plates Hin place without the necessity of the spikes usually employed for the latter purpose.V It is of course obvious that if'the abutment-flanges d were made integral with the foot-flange of the rail or otherwise rigidly secured thereato, so as not to Vdepend on the pressure of the brace-plates for holding them in place, the said brace-plates might rest at their lower edges upon the foot-flange itself, and hence it would not involve a departure from the spirit of my invention to so modify the construction which I have shown.

In the form shown in Fig. 5, which is best adapted for use where the said bearing-plates H are employed, the abutment-plates D, instead of being provided with lugs,as before explained with reference to Figs. 1 and 4:, are provided with sockets or perforations which register with the perforations c in the foottlanges of therail, and the plate H, instead of being provided with perforations for the IOO admission of the lugs CZ, are provided with upl wardly-projecting lugs cl2, preferably formed integrally therewith, which project upward through the registering perforations in the foot-flanges and abutment-plates D. Insome respects this construction is superior to the form shown in Fig. 4, inasmuch as the plates D are easier rolled without the lugs d. It will be understood that in each instance the lugs d are provided asimproved substitutes for ordinary bolts or rivets, which might be passed through the foot-flange of the rail for securing the abutment-plates D in place.
