FISH-PLATE JOINT FOR RAILWAY-RAILS.

SPECIFICATION forming part of Letters Patent N 0. 723,439, dated March 24, 1903. Application filed January 12, 1903. Serial No. 138,648. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM F. Bossnnr, residing at Utica, in the county of Oneida and State of New York, have invented certain Improvements in Fish-Plate Join ts for Railway- Rails, of which the followingis a specification.

The invention about to be described relates to fish-plate joints to support and hold the ends of railway-rails to one another, and provides a new and novel device for the purpose by means of which the rails are held firmly and rigidly.

The joint when in position upon the'ends of two abutting rails consists of two similar independent plates, one on each side of the rail, of about two feet long, preferably of steel plate, each having an extension from near the center of the rail outward beyond the edge of its foot, where it returns upon itself for a short distance, then rises and conforms to the upper side of the foot and the face of the web and makes a bend outward at the curve on the under side of the railtread and returns parallel with, at a distance from, or spaced from the part near the web and terminating in contact with a portion on the upper side of the foot, leaving a hollow narrow space between the parallel parts of the plate near the said web the entire length of the plate, which is filled with a strip of hard wood or other suitable comparatively elastic material. to each other and the rail by bolts which extend through the parallel walls of the plates and the web of the rail, which are provided and secured with nuts. By the wood or other filling in the said spaces the vibrations of the traffic on the rails are taken up, and the boltheads and nuts are provided with cushioned seats and are not readily jarred loose. I provide independent clamps upon each side of the base of the plates, which are connected by bolts and nuts, by means of which the lower parts of the plates are held to the foot of the rail, and notches are made in the sides of the base for the reception of tie bolts or spikes.

The two plates are secured Fig. 2 is an end view of the fish-plate joint, the rail being in section.

Referring to the drawings, ot (1 represent the ends of two rails, and b b are the fishplates, one on each side of the rails, and are referred to by the same reference letters and The ends of the plates under the foot of the rails are separated by a space It and each extends, as a fiat part 1, to beyond the outer edge of the foot, and the plate is there returned upon itself, as at .2, to the edge of the foot, where it rises at the point 3 and conforms to the inclined surface of the foot, and its curve 4 to the web and therealong, as 5, to the curve 16 under the rail-tread, where it forms the curve or half-circle 6, and returns, as 7, parallel with and spaced from the part 5 and the web and abuts at 8 against the portion covering the upper part of the rail. An open space g is thus formed the entire length of the plates b and b which is filled by the insertion of a strip of some hard and elastic material f, as wood, making a very stiff and rigid bar on each side of the rail. The bolts 01 d extend through holes made in the parts 7 and 5, the fillingf, and the web of the rail, which are held together when the nuts 6 are screwed on. The wooden stripf tends to absorb the vibrations produced by the wheels of trains, and thereby remove the jar upon the-bolts, and at the same time it has a cushion effect upon the same, which also prevents-jarring and loosening the nuts. The clamps c o are provided to hold the lower parts of the plates 19 5 together and consist of the plates 10 10 on the under side of the plates 1 1, whose outer ends curve over the ends 2 of the plates, as 11, to grasp the same. Lugs or ears 12 depend from the plates 10, and a bolt 13 extends through them and has upon its end the nut 14, by means of which the clamps are drawn toward each other and also the extremities 2 2 of the fishplates.

Two or more of these clamps are provided for each fish-plate, as may be needed, two usually being sufficient, and are placed at the same distance from each end, leaving a space near the center for the insertion of a wood crosstie t. Notches g are cut in the edges of the plates, into which the tie-bolts or spikes are guided to secure the same to the tie-beams in underside of the rail-foot, the upper sidethereof, the web, and the under side of the rail-tread, then returned parallel with and spaced from the part near the web, and terminating at the portion on the upper side of the foot, the space filled with a strip of hard material possessing comparative elasticity, bolts extending through the plates and web secured by nuts,with clamps extending across the under side of rail-foot and adapted to hold the plates thereto. v

2. The combination of the ends of two railway-rails, with a fish-plate device consisting of two similar plates of steel or iron one end of each separated under the rail by a space and each extending outward and theninward, conforming to the upper side of the rail-foot, its web, and the under sideof the rail-tread, and returning parallel to the part near the web and a distance therefrom to the portionon the upper side of the foot, providinga stiff hollow bar on each side of the rail filled with wood or other suitable'material, bolts extending through the plates and web secured by nuts, with independent clamps extending across the under side of the rail-foot adapted to grasp and hold the plates together.

3. In a railway-rail fish-plate device, two similar metal plates each extending from the under side of the rail-foot to an edge thereof and bent back or returned to the upper side of said foot and continued up the same and along the web to the under side of the railtread and conforming to the same, then returning parallel with and spaced from the part near the web and abutting upon the foot part, the said space filled with a strip of wood or other suitable material, bolts and nuts extending through the plates and web, and two or more independent clamps under the plates provided with bolts, adapted to hold the same together.

4. In a railway-rail fish-plate device, two similar metal plates conformed to theunder side of the rail-foot, the upper side thereof,

the web, and the under side of the rail-tread, then returned parallel with and spaced from the part near the web to the portion on the upper side of the foot, the said space filled with a strip of wood or other suitable material, bolts and nuts for holding the plates and rail together, with independent clamps at the bottom of the plates provided with bolts, adapted to hold the plates together.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 8th day of January, 1903.

WILLIAM F. BOSSERT.
