RAILWAY-RAIL COUPLING.

Specification of Letters Patent.

Patented Aug. 8, 1905.

Application filed May 10, 1905. Serial No. 259,802.

To all whom it may concern: 7

Be it known that I, FRANK N. MARSTON, a citizen of the United States, residing at J ackson, in the county of Jackson and State of Michigan, have invented certain new and useful Improvements in Railway-Rail Couplings; and I do 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, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in rail-couplings; and the object of the invention is to produce a simple and efficient means for holding the ends of rails and preventing the same from creeping; and it consists in various details of construction and in combinations and arrangements of parts, as will be hereinafter fully described and then specifically definedin the appended claims.

My invention is illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this application, and in which Figure 1 is a central longitudinal view through my improved rail-joint and through the rails. Fig. 2 is a cross-sectional view, and Fig. 3 isa detail view of the locking-key.

Reference now being had to the details of the drawings by letter, A and A designate tworails, the meeting ends of which are cut away, forming shouldered portions 13.

C designates a plate having a channel or groove 0' for the reception of the meeting ends of the rails, the walls of said channeled portion conforming to the contour of the opposite web portions of the rail, as shown in the cross-sectional view of the drawings. It will be observed that one of the marginal walls of the channel of the plate is extended to form a bearing to brace the entire web portion of the rail. A portion of the bottom of the channel is recessed away, as at D, the walls of which recessed portion D being inclined to retain the locking-key E, the edges of whichbeing inclined and forming dovetailed connections with the recess. A projection E extends from the key E at one end, and on the opposite face of the key is a projection F, which is adapted to contact with the end of said plate adjacent to the end of the recess in the latter. The projection E is designed to engage the shouldered portions at the meeting ends of the rails and form a stop for the movement of the rail A in one direction.

In adjusting the parts of my invention one of the rails is inserted in the channeled portion of the plate, after which the key E may be slid in the recess formed therefor, and when thus in place the upper surface of the key is'practically flush with the upper surface of the bottom of the channel in the plate 0, after which the second rail is pushed over the plate and in contact with the end of the rail which has been first inserted in the plate, and as the two rails come together the projection IE will form a stop to limit the further movement of the rail in one direction.

From the foregoing it will be observed that by the provision of a rail-joint embodying the features of my invention simple and eflicient means is provided for securely holding rails and preventing the same from creeping.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In combination with a plate which is channeled to receive the meeting ends of rails, a key fitted in a recessed portion of the channel of said plate and having a projection upon one side which is adapted to form a stop against which the shouldered portions of the rail are adapted to contact, as set forth.

2. In combination with a plate which is channeled to receive the meeting ends of rails, a key fitted in a recessed portion of the channel of said plate and having a projection upon one side which is adapted to form a stop against which the shouldered portions of the rail are adapted to contact, and a second pro jection upon the opposite face of said key adapted to contact with one end of said plate, as set forth.

3. In combination with a plate having a channeled portion to receive the meeting ends of rails, one of the marginal sides of said channel being extended to form a brace for the web of a rail, the meeting ends of the rails being cut away to form shoulders, a key having its opposite edges beveled and designed to engage a recess in the bottom of the channel of said plate and have a sliding movement therein, projections upon opposite faces of said key near the ends thereof, one of said projections adapted to contact with said shouldered portions at the meeting ends of the rails and the other to engage said plate, as set forth.

In testimony whereof I hereunto aflix my signature in presence of two wltnesses.

FRANK N. MARSTON.
