ILWAV-RAIL JOINTS.

Specification forming part of Letters Patent No. 194,755, dated August 28, 187-7 application filed July 14, 1877.

To all whom it may concern.-

Be it known that I, HORACE W. WOOD- RUFF, of Cincinnati, Hamilton county, Ohio, have invented an Improvement in Railway- Rail Joints, of which the following is a specification My invention relates to a new and improved method of uniting rails on railway-tracks.

Where the rails are simply united bythe ordinary fish-plate, and spaces are allowed suflicient for the expansion and contraction of the rail, a heavy locomotive-wheel striking the end of the rail as it passes over it presses it down somewhat, and occasions a jar as it strikes the. end of the contiguous rail.

My invention is designed to obviate this difficulty, and unite the rails in such a manner as to form a continuous rail, over which the train passes without jar. I

In my drawings, Figure 1 represents aside view of the device, showing the rails united. Fig. 2 represents a longitudinal section of the same taken horizontally. Fig. 3 represents the rails disunited, and shows the peculiar construction of the contiguous ends,

A and B represent, respectively, the contiguous ends of the rails that are to be united. C Crepresent the ordinary fish-plates. D D

fish-plates and rails, making the ordinary joints. E represents ahorizontal projection or tenon, formed atthe end of the rail, and made with shoulders 42 e e, and which fits into a corresponding horizontal recess, f f f,

in theend of rail B. This tenon is made horizontal, so that the part F overlapping onto the projectionsE of therail A, fills the space the rail A.

It has been attempted to unite rails by tongue and recess arranged vertically at the end of the rail, but the details were difi'erent from this here described, and the device was not a success, as it presented a narrow surface on the top of the rail that was liable to become broken or wedged together, and it did not prevent one rail from sinking lower than the other.

By my invention the top of the rail remains whole and firm, and in the expansion and contraction there is no interval made between the rails, but there is a continuous even rail, the tongue preventing one from sinking below the other.

The enlargements H H may be omitted, if desired, and the device can be used either with or without the fish-plates.

I intend to make this tongue and recess upon the respective ends of the rails bycutting out the parts with a die after the rail is finished.

I claim as my invention- 1. The horizontal tongue E and corresponding recess F in the webs of the contiguous ends of the railway-rails, the heads and bases of which are of the usual form, with squarely abutting ends, substantially asv and for the purpose Specified.

2. The combination of horizontal tongue E and corresponding recess F with the fishplates C C, as and for the purposes described.
