CHARLES H. LITTLE, OI CHICAGO, ILLINOIS.

RAIL-JOINT.

Y To all whom it may concern:

Be itknown that I, CHARLES H. LITTLE, a citizen of the United States, residing at Chicago,-in the county of Cook and State of Illinois, have invented new and useful Improvements in Rail-Joints, of which the following is a specification.

My present invention has reference to railway construction.

My object is to roduce a means whereby railway rails will e connected in asimple, easy, strong and eifective manner without the employment of fish plates or analogous means.

A further object is to produce a rail joint in which the ends of rails rest on a plate, said rail ends having their base flanges slotted to receive lugs that are integrally formed on the plate, an inlay being arranged in the heads of the rails at the said ends whereby the gap between the rails, incident to the expansion thereof will be overcome and a substantially continuous rail presented, the securing means which pass through the plate for sustaining the same on the supporting ties, contacting the longitudinal edges of the rails and permitting the necessary expansion and contraction of the rails.

The foregoing, and other objects which will appear as the nature of the invention is better understood, may be accomplished by a construction, combination and operative association of parts, such as is disclosed by the drawings which accompany and which form part of this application.

In the drawings a Figure 1 is a side elevation of the improvement.

Fig. 2 is a top plan view thereof.

Fig. 3 is a sectional view on the line 3-3 of F 1g. 2.

Fig. 4 is a fragmentary sectional view on the line 4-4 of Fig. 2.

Fig. 5 is a perspective view of a rail end.

Fig. 6 is a view of the chair plate.

The rails 1 have their body portions of the usual construction to each include a head 2, base flange 3 and a web 4 connecting the head and flange. Each flange at the end of each of the rails is formed with a slot 5. Preferably the longitudinal walls of the slot are flared downwardly so that the said slots are substantially wedge shaped.

The head of each rail, at the end thereof, is formed with a longitudinal slot 6, and the side walls of these slots are also flared.

Specification of Letters Patent. Patented Sept. 13, 1921. Application filed May 28, 1921. Serial No. 473,291.

The rail ends rest on plates 7which are disposedover supporting ties 8. Each plate 7 is provided with apair of spaced longitudina'lly extending lugs 9, the said lugs being wedge shaped in transverse section to engagewith the wedge slots 5 in the confront- The plate 7, in a line with the outer edges of the flanges of the rails is provided with a series of spike openings 11 through which pass spikes 12 that have their body portions contacting with the edges of the rail flanges and their heads disposed over and in con tacting engagement with the upper faces of said flanges.

From the foregoing description, when taken in connection with the drawings, it will be noted that I have provided a simple means for effectively connecting the confronting ends of railway rails, one in which the employment of fish plates or analogous devices which necessitates openings in the webs of the rails is avoided. The plates 7 are comparatively long, and therefore effectively support the rail ends. Thus the rail ends will be held from sinking, and incident to the wedge engagement between the lugs on the plate and the wedgeslots in the base flanges of the rails relative vertical move ment cannot take place. The inlay 10 is in the nature of a steel bar, and incident to the shape thereof cannot work either upwardly or downwardly in the slots that receive the same. As a consequence, the bearing surface of the wheels of the rolling stock will ride over the inlay in passing the joints of the rails and will be prevented from sinking when the rails are separated by contraction.

The ends of the rails are similarly shaped. The lugs are not necessarily wedge shaped so that one rail may be removed from a track without interferring with the remaining rails.

Having described the invention, I claim 1. In a railway construction, the combi nation with rails and supporting ties therefor, of a plate disposed over certain of the ties, said plate having a pair of spaced lonmews- LMA 'gitudinal lugs which are wedge shaped in cross section, the rails having their base flanges, to the opposite sides of their webs formed with wedge slots to receive the lugs, and means passing through the plate, entering the ties, contacting the edges of the base flanges and overlying and contacting with the top of said base flanges.

2. In a railway construction, the combination with ties, of a plate arranged over the ties, said plate having a pair of spaced longitudinal lugs which are wedge shaped in cross section, rail ends designed to be received on the plate having their base flanges, to the opposite sides of their webs slotted CHARLES H.
