FASTENING FOR RAILWAY-RAILS.

SPECIFICATION forming part of Letters Patent No. 549,616, dated November 12, 1895.

' Application filed March 4, 1895. sum No. 540,493. No model.)

-Railway-Rails; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to fastenings for railroad-rails, street-car rails,-T-rails, and in fact for all rails and beams used for any purpose for traffic and in the construction of buildings, bridges, and wherever it is required to use iron beams and couple the ends together. It is particularly well adapted for rails designed to support rolling-stock, as it practically makes a continuous rail and obviates independent vibration of the opposing ends of two rails on the approach and passage of the wheels of a loaded car, thus preserving the road-bed at the j oints'of the rails by preventing the usual vibration and jarring of the rail ends, this preservation of the roadbed at the rail-j oints being an important prac tical advantage of my invention, as it has heretofore required more labor to keep up the roadbed at rail-joints than at any other points of the road. The jolt orj ar incident to the wheels of a train passing over the joints between the rails is too well known by the traveling publie to require an extended description of the same, and the inconvenience and annoyance caused by such jolting has frequently been complained of and deterred persons in ill health from traveling by rail.

The present invention aims to provide a splice or coupling between the ends of rails or beams which will make them practically continuous and when applied to railroad and street-car rails will wholly obviate any jolt or vibration of the ends of the rails when the wheels of the car are passing thereover. This independent vibration of. the rails is the chief cause of the loosening of the fastenings at the joints or fish-plates, thereby necessitating the employment of men to Walk the tracks and tighten the nuts of the fastening-bolts.

By my inventionthe vibration is reduced to a minimum and the fastenings are not so quickly loosened. Hence the track-walker can cover at least twice the amount of ground as heretofore. Suppose the distance previously covered by one track-walker by the old method of laying the rails to be about two miles. By my invention the same person in the same time-say one daywill cover about four miles or twice the distance heretofore covered; hence the advantage of the invention, viewed from an economical point of View, not to say anything of the ease and convenience to the traveler by the absence of the jolt and jar, now so common.

The preferred form of coupling is T-shaped, or approximately so, and is adapted to enter or be fitted into notches in the ends of the rails, said notches being provided in the web portion of the rail ends.

The improvement also consists of side pieces or segments to overlap the joint between the rails and hold the coupling in place, said segments being secured to or forming an integral part of the coupling, as found most convenient, the latter construction being preferable. These segments have depending lugs at their ends to interlock with slot-openings formed in the foot of each contiguous end of the rails, thereby forming a firm and efficient joint to effect the desired result, while the said slots permit of the expansion and contraction of the rails.

The improvement further consists of splicebars to be used in connection with the coupling to strengthen the joint and brace the same firmly and securely. These splice-bars are arranged one on each side of the web porshowing the manner of placing the coupling in place. Fig. at is a perspective view of the coupling. Fig. 5 is a top plan view of the same. Fig. 6 is a detail View of one of the splice-bars. Fig. 7 is a bottom plan view of the adjacent rail ends.

The invention is shown in its more general application in the annexed drawings, in which A and B represent railroad-rails of ordinary construction, the ends being provided with notches G to receive the coupling 1) and having elongated openings or slots E in the foot or base flange a short distance from the ends to receive lugs f, pendent from the loweredge of the side pieces or segments F. This coupling may have various forms and shapes so long as it will interlock with the ends of the rails and cause them. to move together as one piece, but is preferably formed, as shown, of a substantially T shape, the head of the coupling being formed with a perfectly-flat horizontal top 1), and the notches C in the ends of the rail'webs are of corresponding shape to receive and form a close joint with the said coupling, having the horizontal top shoulders C, which rest upon the horizontal top D of the coupling-block. It will be seen that by this construction, when the rails contract the straight horizontal shoulders C will always keep in the plane with and rest upon the flat horizontal top I)- of the couplingblock, thus giving a solid bearing to the rail ends, both when expanded and contracted, so that it will be impossible for the rail ends to give down at any time under the pressure of the wheels passing over them, which might, during contraction of the rails, occur were this bearing a curved instead of a perfectlyhorizontal one.

The parallel side pieces or segments F F. overlap the joint between the ends of the rails, fitting snugly on each side of the railwebs, and have lugs. f, pendent from their lower edges to enter the slot-openin gs E, and are provided one for each side of the rail, and are formed preferably integral with the coup.- ling-block D. The segments ma y,however,be formed separate, when desired, and secured to the coupling-block by bolts, rivets, or inany desired manner. The lower edgesof the segments rest upon the foot-flange of the rails and their upper edges curve from the middle toward each end, the segment onthe inner side of the rails being formed with two lugsat each end. extending down from its lower edge and. passing through two corresponding slot-open-.

ings E in the base-flange 011. the inner side of the rail, while the outer segment has-one lug depending from each end and entering a corresponding opening in the outer base-flange, or two lugs at each end, whendesired. this arrangement the openings in the railflanges are not directly opposite-each other,

thereby preventing any weakening of the rails at that point. The number of lugsemployed may, of course, be varied. according to the length which the segments are made,

as the nature of the rails, the purpose for which they are intended, may direct. The lower horizontal edges of the segments rest upon the base-flanges of the rails and their upper edges curve from the middle toward each end, the lower outer part of each segment being rabbeted at F to receive the inner edge of the horizontal lower portion of the splice-bar G.

The coupling is placed in position by elevating the ends of the rails to be coupled, as shown in Fig. 8, sufficient to admit of the T- head of the coupling entering the deepest portion of the notches formed in the ends of the rails. After the coupling is properly positioned the elevated ends of the rails are lowered, when the coupling will enter the notches in the ends of the rails and the parallel segments will come one on each side of the web of the rail. This operation also admits of the proper entry of the lugs f into the elongated openings E. The coupling 1), fitting in the notched ends of the rails and the parallel segments extending on each side of the web of the meeting rail ends, with their horizontal lower edges resting upon the base-flanges and their bottom lugs f seated in the openings in said flanges, form a coupling device which of itself will secure the ends of the rails together firmly and securely, while additional strength and solidity are secured by the splice-bars G, which will be now described; also, the bottom lugs f are inclined or beveled on their outer sides, so that when the weight of the car-wheels is passing over them tending to press them down farther in the openings E, these inclined faces will operate to bring the twoparallel segments F closer together as they are pressed down, aswill be readily understood.

The splice-bars G, one for each side of the rails, have their middle portion cut away to exactly receive the segments and have each a horizontal base portion G, which rests upon the raihflange and is spiked to the ties at g in the usual manner. The bodies of the splice-bars are rectangular, their upper edges fitting. against the under side at the head of the rail, filling the. space between the head and foot of the rails and bracing the joint against vertical stress, and in this respect supplements the action of the couplin \Vhen the coupling D F F has been seated in position and thesplice-bars G G secured in position, their openings G2 exactly receiving the segments F, the outer faces of which lie flush with the outer faces of the splice-bars, ajoint is thus formed at the ends of the rails which is absolutely firm and solid, preventingallivibration of the rail ends and making the rails practically continuous, while the rails are actually stron ger and will resist more strain at these joints than at any intermediate points of their lengths.
