IMPROVEMENT IN RAILROAD-RAIL JOINTS.

Specification forming part of Letters Patent No. 173,350, dated February 8, 1876; application filed November 19, 1875.

To all whom it may concern:

Beit known that I, JOHN SHINN, ot' Philadelphia and State of Pennsylvania, have invented an Improvementin Railway-Rail Joints, ot' which the following is a specification:

The object o t' my invention is to provide a secure and permanent rail-coupling at the joint of a railway-track, and also to prevent the sliding or slipping ot' the rail out of the coupling or tie;` and consists in the combination of a coupling or tie provided withy two hollow tapering keys having a bolt passing through them, with a brace-bolt that will act as a stop to preventthe tie from sliding on the rail, and, at the same time, act as a brace to strengthen the coupling or tie.

Figure 1 represents a cross-section of my improvements; Fig. 2, a longitudinal View of the tie; Fig. 3, a top view of the tie and improvements 5 Fig. 4, a view of the brace; Fig. 5, a view of the taper keys and bolt.

Similar letters in the drawings refer to like parts.

The tie A is cast in one piece, and with a suitable recess to receive the endsof the rails R, and one side is provided with two tapering hollow keys, B B, which enter at opposite ends of the tie, and are drawn toward the center by the bolt C which passes through them, by which means the ends of the rail are held irmly in the tie. This part of the tie is not new and is fully described in Patent No. 23,390, March 29, 1859, and, therefore, will not require further description here.

D is the brace, and-is made as shown in Fig. 4. One end is cut with a screw-thread for a nut; the other end is turned or bent to tit round the edge of the tie A. In the ends of' the rails are cut a notch, E, (see Fig. l.) When tie, and the opposite end is hooked to the edge of the tie. screwed tight.

The nut is then put on and the ends of the rail in line. Should the keys get loose, the brace C will prevent the tie from sliding 0E from either end of the rail forming the joint, and, at the same time, greatly strengthen that part of the tie for the keys B B.

When it is desirable to take up and remove a rail, the brace D can be removed, which will allow the tie to be slid to one side and break thejoint. vOther rails may be putin and keyed up, as before described.

The tieA may be made eithercastorwrought iron, the keys of cast-iron, the nuts should be lock nuts, to prevent them from shaking loose.` p'

Tie A and taper keys B B, provided with a bolt, C, in combination with the brace D, as described, and for the above purpose.

JOHN SHINN.

The keys B B are then putin. from opposite sides, and a bolt, C, is passed through them, and by screwing the nut the' keys will be drawn together and firmly hold
