INIPROVED' RAILWAYQRAIL.

To all whom it may cmtcern:

Be it known that I, Denison OHAUNCY PIERCE, of Clayton, in the county of Jefferson, and State of New York, have` invented new and useful Improvements in Railroad-Rails; and I do hereby declare the following to be a full, clear, and exact description of the nature, construction, and' operation of the same, suflicieut to enable others skilled in the art to which my invention appertains, to make and use the same, reference being had to the accompanying drawings, forming part of this specification, and in which- Figure 1 represents a transverse vertical section of my improved railroad-rail; and

Figures 2 to 12, inclusive, are modiications of the same.

This invention relates to improvements in the com-l pound railroad-rail, for which Letters Patent were granted to me, bearing date March 27 1866, and numbered 53,479. In this patent, the rail is constructed in two part-s, one of which constitutes the body, or main rail, and the other forms the cap, or head thereof, and serves as the table of the rail. Strips of prepared wood, or other suitable material, are placed -between the cap and main rail, and all fastened together. By this arrangement the blows of the'wheels of the passing trains are delivered upon the adjustable cap of the new rail, while it does not oppose a rigid resistance thereto, but yields to the extent of the material between it and the main rail.

The present invention has for its object to so construct the main rail as to utilize the material of which it is composed, and at the same time .to so dispose the same as to aford the greatest possible lateral and vertical resistance to the strain incident to the passage over it of heavy-laden trains.

Similar letters of reference indicate corresponding part-s in' the several figures.

A represents the cap, composed of steel or iron, as shown in the patent hereinbeforereferred to; and

B is the main rail.

` In g. 1, this rail is shown, formed with a downward-projecting flange, C, adapted to be let into the tio, for the purpose of holding it securely in place, at the same time permitting the lateralilanges D D, upon each side of the rail, to rest upon the ties, and aiibrd a firm support for the tread, or cap.

The upper or vertical parts, E, of the main rail, are made hollow, having two ilanges upon each side, vin older to dispense with a large quantity of metal.

It is not-necessary that this portion of the rail should be made solid, as the additional strength gained would be insuflicient to compensate for the cost of the material.

I design to roll the main rail B in one piece, but,-

if found preferable, it may be rolled in two pieces, as' indicated by the dotted lines in the flange C.

b b b are strips of wood, or other elastic and suitable material, interposed between the cap and main rail, as before mentioned.

The portionof main rail between the ilanges E E may also be lled with wood, but I prefer it to be of cement, being more economical.

Fig. 2, the main rail is composed of two pieces, B, with their upper sides lapped over each other, s shown at c. By this construction the rail is made hollow.

The main rail may also be made in two parts, with their upper and lower sides overlapping each other, as atc, fig. 3. In this figure the downward-projecting portion c is also made hollow. l

. Fig. 4 shows the rail made in two parts, `ioined together in the horizontal line x x.

In fig. 5, rail is made in one piece, open at the topv b, and filled with wood or cement.

Fig. 6 is the converse of iig. 5, having the lower portion C open, and its top E closed.-

Fig. 7 is the same as fig. 1, with the flange O removed.

In iig. 8, the parts C E are hollow, and open at the top and bottom, respectively. These parts are in the form of parallel iianges, crossing the lateral flanges D D at right angles, and extending equal distances from each side of the rail. Y

In the foregoing description, it will be seen that the form of rail, in all cases, embraces similar disposition of metal, and, furthermore, the greatest possible strength. The whole rail may he fastened to the tie Aby bolts or screws, extendingthrough the'ilanges of the cap and main rail, or by headed spikes upon each side-of the langes, inthe usual manner.

Having thus described my invention, v

I claim as new, and desire to secure by Letters Patent-l As an improvement upon my patent, granted March 27,1S66,No. 53,47 9, the construction of the mainor base rail, when the same is provided with broad lateral flanges and a lower vertical flange, and'when the central upper portion of the rail and lower'vertic-al flange, either or both, are made hollow, and the rail is combined with a suitable cap and interposed strips,-

substantially as and for purposes set. forth.
