GEORGE P. ROSE, OF ELMIRA, NEV YORK.

IMPROVED RAILWAY-RAIL SPLICE.

To @ZZ whom, t may concern.-

Be it known that I, GEORGE I. RosE, of Elmira, in the county of Chemung and State of New York, have invented a new and useful Improvement in Railway-Bar Joints; and I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon and being a part of this specication.

Figure l is a perspective view of a section of track at the point where adjoining rails meet. Fig. 2 is a sectional end View of my fish-plate. Fig. 8 is a plan view of my nut-look. y

Like letters indicate like parts in each iigure.

My invention consists in rails provided with offsets and shoulders upon their ends, so as to t together, and with rectangular holes through the web for the reception of bolts, in combination with a fish-plate and chair combined, and a locking-plate.

In the drawings, A represents the wooden Stringer-s or timbers, which, in practice, will rest upon suitable ties, and upon which the rails B are secured by wood-screws af, with elongated heads, the widths of which are equal to the body of the screw, while the pro- 'ectinOp heads u on o osite sides actin@P J s 7 C,

as ilanges, will allow them to grasp and hold the foot of the rail to the stringer. Vhen it is required to release the rail from the stringer, it may be done by giving the screws a quarter of a turn, thereby disengaging the head from the railfoot. The ends of these rails are halved together, as shown at b-or, in other words, are provided with an offset and shoulder, as shown, the one lapping by and abutting against the other. A chair and fish-plate combined, made in two sections, C and D, re-

ceive the foot of the rail, and are iitted to the flat or concave sides of the web of the rail, in reference to which they are so situated that the overlapping ends of the rail will be about the center of the length of the chair and ishplate.

Equidistant from each other through the ends of the rail, and correspondingly through the fish-plate, are punched as many rectangular holes as it is designed to use bolts to connect the rails and sh-plates together. It is not necessary that these holes should be equidistant from each other, although it is preferable, in order to secure greater uniformity in the work. Itis, however, essential that in their vertical section they should correspond with the size of the bolts, while it is equally essential that in their horizontal section they should be longer than the width ofthe bolts, in order to allow for the contraction and expansion of the rails under varying temperatures. The bolts E, which are shown in a separate figure, are rectangular in shape,

the end, of course, being drawn down and rounded to receive the thread with which the nut o engages. v

The vibration caused by passing trains, concussion, or accident frequently causes the nuts to loosen and fall oit', which are usually employed in securing fish-plates to the rails. To remedy this evil, I employa plate, F, with four holes, d, punched thereon, of suitable size to t the nuts c. This plate is placed against the fish-plate in such a manner that the nuts c will protrude through the holes d, and is held in position by another rectangularshaped bolt, H, passing through corresponding holes of corresponding shape in the plate, fish-plate, and rail. Through the end of this bolt there is drilled a small hole to receive the pin e, which engages with a slot in the outer face of the nut f, and effectually prevents it from turning or becoming loosened.

The holes through which all the bolts E and H pass in the iish-plates and locking-plate should be of a size to tfthe bolts; but the corresponding holes through the rails should be elongated, as and for the purpose herein before described.

Suitable bolts G, which, as they are under ground, should bc galvanized to prevent corrosion, are employed to hold the stringers in their `relative positions and prevent their spreading or drawing together. These bolts should be provided with shoulders g, against which the inner faces of the stringers rest, and nuts h upon the ends, which pass through the stringers.

Proper tubes or openings, K, laterally and downward through the stringers, will allovtr the Water, which would otherwise settle there, E and H, in combination with the fish-plate to pass off from between the two legs of the and chair combined, C and D, and the locktraok. ing-plate F, substantially as :md for the pur- VhzLt I claim as my nventomzmd desire to pose specified.
