EAELRUAB TRACK.

SPECIFICATION forming part of Letters Patent No. 38,620, dated June 19, 1888..

Serial No. 367,662. 2T0 model.)

Be it known that I, .inoon HAISH, a citizen of the United States, residing at lie Kalb, in the county oflJ-e Kalb and State oflllinoishave invented certain new and useful Improvements in Railroad-Tracks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will onable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

lily invention has reference to improvements in railroadtracks; and it pertains more especially to an improved mode of effecting the junction of the ends of the rails therein, and to secure the permanency ol' the conformation of the crown of the rail at each end, so as to prevent the battering down of the extreme ends of the rails, so common in the present construction, and which produces an objectionable unevenness in the crown oi. the track, and. also to provide against the displacement of the rail in case of its fracture.

In the drawings, Figure l is a side elevation of a portion of a railroadtracl; provided with my invention. Fig. 2 is a cross-section thereof in the line a oi' 1. Fig. 3 represents details of bolts 4-. and fish-plates 9 and section of the rail. 1.

l. is a rail, which has formed, centrally in the base thereof a vertical slot or recess, 2, extending throughout the entire length of the rail. A bar 01' iron, 3, cl suitable size to substantially fill laterally the lower end of the recess 2, placed edgewise therein, and extends any desired distance within the rail from the end thereof, and is held in position by one or more transverse bolts, 4:, passed through the adjacent sides of the rails 1. and through the bar 3, and seated and held in position as hereinafter described.

The plat-i ol' the bar 3 within the recess 2 prevents the displacement of said bar from any casual loosening of the bolts 4, it being obvious that such bar 3 will remain in place and perform its function reasonably well so long as even one of the bolts i remains in po sition, and will not fall away from the track 1., as is the case with the ordinary fish-plates when their bolts become loose.

The recess 2 is formed somewhat deeper vertically than the! vertical diameter of the bar 3, and as the base of the bar 3 rests upon the same plane as does the track 1 an unoccupied space is provided at the top of recess 2. In the extreme upper end of the recess 2 is firmly forced, and thereby seated, the wire rope 5,0f a suitable diameter to be solidly em bedded within the upper end of the said recess 2.

The rope can be extended entirelythrough the rail 1 and through thejunction of the rails 1, if desired, whereby said rope ail'ords further seeurityin retaining the several rails l in line in case of any defect in or accident to the other devices for effecting the junction of said rails; and said rope 5 will have the further nnction of holding the parts of the individual rails in proper line in case of casual fracture of the latter between their extremities. The derailing of the train in case of broken rails is occasioned by the ends of the broken parts being pressed out of alignment with each other. Even in case of a fracture of the rail 1 between its extremities the rope 5 will hold the parts in alignment long enough for the detection of the fracture, and meanwhile prevent the broken parts from getting out of alignment, and thereby save the train from. leaving the track.

To provide against the battering down of the crown of the rails 1 at their extremities, I interpose between the adjacent ends of said rails a short piece, 6, of hardenedsteel rail, having the same conformation as the rail 1, and provided also with a like recess 2. The bar 3 and rope 5 are projected longitudinally through the interposed block 6, in the same manner and for the same purpose as hereinbefore described in reference to the rails 1.

It is impracticable to utilize rails 1 of the same degree of hardness as that which inheres in the block 6, for the reason that the lateral rigidity of the rails 1 would occasion the breakage of the latter were they hardened to the above degree; but inasmuch as the block 6 is short, and can therefore yield slightly to lateral pressure, said block maybe made of any desired degree of hardness without exposure to fracture.

As by the interposition of the blocl:

tween the adjacent ends of the rails there are two spaces in lieu of the usual one, each of said end spaces may be narrower than that usually employed, and yet leave room for the necessary contraction and expansion of the rails 1, and there is thereby avoided the usual width of space which permits a slight drop of the wheels, resulting in battering down the adjacent ends of the rails. The block 6' is held in its relative position withthe adjacent rails l 1 by the bar 3 and rope 5, aforesaid.

7 is the usual tie, placed transversely of the track, under and extending each way from the point of junction of the block 6 and rails 1.

Sufficient space is reserved in the recess 2, and the same can be utilized for the reception and seating of properly-insulated telegraph.

and telephone wires. This would not only avoid the expense and delay caused by storms beating down the present poles and wires thereon, but would be extremely convenient for telegraphing to and from the passing trains.

To yet further strengthen and secure the point of junction of the rails 1, I provide the sides of said rails for a short distance inwardly from the ends thereof with the longitudinal corrugations 8. Lateral and external fishplates 9 are also provided on each side of the rails 1, extending over the point of junction of the latter and held in place by the aforesaid transverse bolts 4.

On the inner impinging sides of the plates 9 are formed cross-corrugations 10, and when the plates 9 are laid in a horizonal position parallel with and on each side, respectively, of the rails 1, the corrugations 10 ot' the plates 9 will rest at right angles upon the corrugations 8 of the rails 1 and afiord a certain degree of elasticity as against the tension effected through the bolts 4. The fish-plates 9 are formed with an outwardly-extending base or flange, 11, which latter, when the plates 9 are in position, rest upon the usual lateral outwardly-extending flange of the rails 1. The under side of the flange 11 of said plates is also provided with crosscorrugations corresponding with the vertical corrugations 10.

In each end of the vertical portions of the plates 9 is formed a horizontal longitudinal slot, 12, having open ends externally. The slots 12 are designed as the seats of the end bolts, 4, and are of such length and relation that the plates 9 can be passed in behind the heads of the bolts 4 or removed therefrom for the purpose of repairs, in the case of substitution of rails, or otherwise. One or more bolts 4, intermediate the slots 12, hold the plates 9 from displacement by horizonal shifting when said plates are in use, and to remove and re place the plates 9 it is necessary only to withdraw these intermediate bolts, 4.

The bolts 4 are formed with the head 13 extending obliquely downward, and are provided with external flanges, 14, which, when the bolt-head 13 rests upon the lateral flange of the rail 1 or upon the ties 7, is adapted to be held firmly down by the usual laterally-exon the bolt 4 just within its head, which in p the tightening of said bolt abuts against the outer side of the adjacent fish-plate 9, and affords means for the requisite tightening by means of the thread and nut on the opposite end of said bolt.

One half of the bolts 4 are inserted from the outside of the rails 1 and the other half to the inside thereof, and it is obvious that the spike 15 will hold the bolts 4 in position, even should the nut upon the latter be shaken off, and thereby the position of the central bar, 3, and fish-plates 9 will be secured, notwithstanding the loosening or displacing of all of the nuts on said bolts.
