RICHARD P. MORGAN, JR, .0]? DVIGHT, ILLINOIS.

RAILWAY-RAIL JOINT.

SPECIFICATION forming part of Letters Patent No. 280,654, dated July 3, 1883.

Application filed December 6, 1882. (N0 model.)

To all whom it may concern Be it known that I,,RIGHARD P. MORGAN, Jr., a citizen of the United States, residing at Dwight, in the county of Livingston and State of Illinois, have invented certain new and useful. Improvements in Railway-Rail J oints; 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, referencebeing had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form apart of this specification.

My invention consists in placing underneath the joints of the rails of railway-tracks what, by way of designation, I call a sub-rail, and securing the same to the track-rai1s by a series of clamps and keys or nuts, so that the trackrails and the sub-rail may be firmly held or clamped together, and both may be supported by the cross-ties, as hereinafter described.

The accompanying drawings are referred to as a part of this specification.

Figure 1 shows a longitudinal view'of the track-rails, the sub-rail, and the ends of the ties supporting the same, and also the fasten ings which hold together the track-rails and the sub-rail. Fig. 2 is a cross-section of the track-rail, sub-rail, and clamp, and exhibits the rabbet in the end of the cross-tie, where the base of the sub-rail rests. Fig. 3 represents a perspective view of the key which may be used to fasten the clamps in place.

The letters on the different figures refer to the same parts.

(t represents the ordinary rails of a railway, which I have designated as the track-rails.

I) represents the sub rail, the middle of which is placed under the joint of the trackrails.

0 represents the clamps which are used to fasten together the track-rails and the sub-rail.

(2 represents the cross-ties, with the rabbet in the end of each of such depth that the ties support both the sub-rail and the track-rails.

6 represents a lip rolled on the outer edge of the top of the sub-rail, so that the foot of the track-rails may be held in alignment and the track prevented from spreading.

f represents the key-holes in the ends of the clamps c, in case the clamps are secured by keys instead of nuts.

9- represents the wedge-shaped key which is used to secure the clamps in place.

i shows the form of the interior of the clamp, so made that its inner surfaces correspond to and rest fairly in contact with the foot of the track-rail and the head of the sub-rail.

Zin Fig. 2 shows the rabbet in the cross-ties.

Two or more holes or openings should be made in the sub-rail, corresponding with simi lar holes or openings in the trackiails, for the reception of the ends of the clamps, as shown. The clamps should be formed approximately like a capital U in their exterior figure. The interior of the clamps should conform with the track-rails and sub-rail, so that when drawn to place they will hold those rails firmly together. The clamps may be inserted in oppo site directions, as indicated in Fig. 1, or they may all be placed on either side. WVhen the key 9 is inserted in the key-hole f and driven home, it draws the clamp c and holds it in contact with the track-rails and the sub-rail and binds them firmly together. The subrail should be of such length as to extend from the middle of one crosstie to the middle of the next, and of such depth that when it rests on the bottom of the rabbet the track-rails should rest upon the top of the sub-rail, and also on the top of the cross-tie beyond the rabbet. This difference in distance is to provide against the effect of the expansion and contraction of the track-rails, so that with each change in temperature a change in the position of each clamp will take place and maintain a uniform compressive strain binding the trackrails and sub-rail together, and is computed to be applied to track-rails of thirty feet in length. If longer or shorter track-rails are used, these distances should be varied accordingly.

The material of which the sub-rail, clamps, and keys are made may be either iron or steel.
