. IMPROVEMENT IN RAILWAY-RAIL JOINTS.

Specification forming part of Letters Patent No. 1 60,916, dated March 16, 1875 application filed January 27, 1875.

To all whom it may concern:

Be it known that I, JOSEPH M. KENNY, of Blairsville, in the county of Indiana and State of Pennsylvania, have invented a new and Improved Combined Fish-Plate and Fastenin g for Railroad-Rails; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing forming a part of this specification, in which- Figure 1 is a side view of the railroad-fastening; Fig. 2, a transverse section through line a: 00.

This invention relates to certain improvements in fish-plates and fastening for railroadrails and consists in the peculiar construction and arrangement of the said plates and the clamping-bolts, as will first be fully described, and then pointed out in the claim.

In the drawing, A represents the two ends 'ofadjoining railroad-rails, which are perforated in the center with longitudinal slots at for the insertion of the clamping-bolt, the said perforations being in the form of a slot instead of a circular hole, to admit of the expansion and contraction of the rails due to variations in temperature. B B are the fish-plates, which are also provided with slots 12 1), plate B having around each slot 1) spaces 0 d. C is the clamping-bolt, which is made with a diamondshaped head, D, and a transverse locking-bit,

E, the end of the bolt being screw-threaded, as usual, to receive a nut, F, which fits in the depression 61 on the outside of fish-plate B. The bits E are passed through the slots at and bin a horizontal position and then turned,

thus locking plate B to the ends of the rails. Plate B is then put on and the nuts F screwed upon the stems of the bolts until they will go no farther. They are then arranged with their sides conforming to the depression 01, and the bolt turned by means of the head D until the devices are tightly locked together, the diamondshaped head enabling the workman to ascertain when the bits E are in a position transverse to the slots, as they ought to be.

By means of this arrangement the devices are tightly locked together, the depression (I preventing the turning of the nut, and the bits E still holding plate B to the rails in the event of the loosening of the nut.

Having thus described my invention, what I claim as new is The combination of the bolt 0, having the locking-bit E, with the plates B and B, the latter having spaces 0 and d, and the nut F,

substantially as and for the purpose described.
