UNITED STATES PATENT OFFICE ALBERT WILLIAM ROGERS, OF SANCHEZ, DOMINICAN REPUBLIC RAILWAY TRACK Application led June 30, 1927, Serial No. 202,624, and in Great Britain February 11, 1927.

This invention, which relates to railway the length of the rail and disposed one each tracks, consists in the provision or" a track side et the thin end of the web2 aforesaid. which includes rails of a more or less T- .Each sleeper 4, of convenient length, headed shape with wedge-like web, rail width and thickness, is made oit concrete jointing with wedge-like sleeves or comrointorced by means of longitudinally dispound fish-plates and special keys tor use posed hook-ended round metal bars 5 to therewith, rail chairs et a more or less withstand the pressure which is applied in horseshoe shape in cross-section, with spea lateral direction by the keys and rail cial keys for use therein, and sleepers chairs 6, which latter are embedded in wherein no bolts, spikes or screws are emgauged distance apart in the concrete sleep- 60 ployed to make the fastening between rail er 4, said sleeper 4 being on its underside ends, and between rails and chairs, or beiornied with flat ends or bearing surfaces 7 tween chairs and sleepers when concrete connected together by a central and upsleepers are employed, an-d in which sleepwar-diy curved portion 8.

justed to engage both rail ends the semi-circular grooves 3 in the underside of the head 1 oi' the rail, in this way is said rail suspended by the two keys 11 and 12 aforesaid, with the end of the wedgeshaped web 2 clear of the bottoni of the chair 6 aforesaid.

Further, the inside key 11 is formed with 'tically disposed triangular groove lil (see rigure to coincide, after adjusting key 11, with a vertically disposed triangular groove 15 in the aujacent wall ot the chair o', and into the square hole thus tor-ined there is fitted a slightly tapered squared plug 16 which locks said key 11 to said wall, whilst the outside key 12 is formed with four vertically disposed triangular grooves 17 (see Figure arranged parallel to one another, and the wall adjacent said key 12 is formed with five verfically disposed triangular grooves 18, on,v one of which is shown in Figure 5, arrangparallel to one another to form. when a groove 17 in the key 12 aligns with a groove 18 inthe wall, a square hole in which fitted a slightly tapered squared plug 19.

F or each rail joint (see Figures 3 and 4:), there is employed a. compound fish-plate, the sainev comprising a cast-steel sleeve of convenient length and of wedge-shape troughlike cross-section, that is to say, the longitudinal walls 20 of the sleeve incline upwardly and inwardly to one another to receive therebetween the wedge-shaped web 2 of he rail.

ln the upper face of each wall 20 of the sleeve, and towards one end thereof, and which walls taper longitudinally in opposite directions in relation to one another, are formed a convenient number or" transversely disposed triangular grooves 21 (Figure 3) arranged parallel to one another.

Further, two tapered keys 22 are provided, said keys on their upper` face each being' formed withA a longitudinally disposed semicylindrical bead 23 which entends the length of the key y22, and on their lower surfaces with a convenient number of transversely disposed triang'ular grooves 2e arranged parallel to one another.

The 'iointing-up is effected in the following The sleeve is slipped over the end of a rail which, it .is assumed, is in position. The second rail is then placed in position` and secured to its sleepers in the manner previously described, and the sleeve is moved to enable the keys 22 to be inserted under the rail head 1 and on top of the walls 20 of said sleeve, the beadsQS of said keys 22 taking` in the grooves 3 in the underside of the head 1 of the rail. The sleeve aforesaid is then ad- (as shown in `ure 3), whereupon the keys 22 are iirinly dr von in to complete the joint, forcinfr the sleeve downwards so that the walls 20 o1' said sleeve tightly wedge with the wedge-shaped ,webs 2 of the rails.

The j means of a slightly tapered squared plug` 24 which fits in one of the squared holes formed b v one ofthe triangulo r `grooves Qei in said key 22 and one of the triguiar grooves 21 in the walls 2O of the sleeve according to the aligning' position of said triangularvgrooves.

rllhe triangular grooves ir each wall of the sleeve are live in number and half-inch from point to point, giving a total length of twoand-a-half inches, whilst the triangular grooves in each key are four in number, and measure half-inch also in width, but are spaced apart one-eighth-inch, which distance the keys must be moved to enable the plugjr to be inserted into the next square hole presented, the intervening points formed by the triangular grooves being removed to give a suitable clearance.

rllhe kevs 22 are intended to occupy the position in vuneh the second Agroove 21 in a wall 20 of the slee ie alie/,Ins with the first groove 2i in key 22 when first driven, when, for practical purposes and wear and tear, an adjustneert of seven-eighths inch, or seven positions oil the plug, is provided for by the remaining grooves, Y

ln all cases the plugs are dipped in tar be- Y'ore being' nlacefl in position, after which they 1,re inserted and tapped sufficiently to ensure a nfm hold on t ie sides of the hole, the unoccuied grooves in the tapered keys being filled in with grease.

Further, the tapered joint keys may be made concave at the thick end to facilitate their beinei drifted into position, instead of beine' driven, in the event of close joint sleeper spacing being: required.

Although the primary object of the invention is to eliminate bolts, spikes and screws whilst making for extensive use of concrete sleepers, yet the r il section above described and the boltless rail joint can be used to advantage in combination with wooden sleepers and chairs modified to suit said wooden sleepers.

l claim z- 1. i device of the character described including' a sleeve havinfr a base and upwardly extending spaced side walls, a T-shape rail adapted to be supported in :said sleeve, fish plates interposed between said sleeve and rail, said plates and sleeve being formed lwith cooperating locking* grooves, and studs insertable in said grooves for holding said fish plates and rail in adjusted positiony in said sleeve.

2. A device of the character described includinnr a sleeve having a base and upwardly extending; spaced side walls, a -shape rail hai/'ine` a wedge-shape web adapted to be supported in said sleeve, adjustable fish'plates adapter to have Contact with said sleeve and the web and head portions of said rail, the adjacent portions of said sleeve and ish plates kevs are each locked in position by being provided with a plurality of spaced opposed cooperating locking grooves, and locking' lugs receivable in said grooves for holding the leh plates and rail in seid sleeve.

In testimony whereof I have affixed my signature hereto this 3rd day of May, 1927.

ALBERT WILLIAM ROGERS.
