METHOD'OF UTILIZJNG OLD RAILS.

SPECIFICATION forming part of Letters Patent No. SOOAOQ, dated June 17, 3,884.

Application filed February 7, 1884. {No model.)

To all whom it may concern.-

Be it known that I, GorrLinn A. Srnrnnn, of Allegheny City, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Methods of Utilizing @ld Rails; and I do hereby declare the following to be a full, clear, and exact de scription thereof.

My invention consists of an improved methodof utilizing old railroad-rails and rail ends, and particularly old steel rails.

The special object I have in view is the pro duction ofnail-plates; but the invention is also applicable to theproduction of other forms of sheet and plate manufacture. Old steel rails have been made into nail. plates by cutting off the flange, so as to leave the head and web in. one piece, then cutting up the two pieces thus made into short lengths, and, lastly, rolling the lengths down into plates by passing them through rolls in a line parallel with the axes of the rolls. This method produces only a narrow plate.

lvIy invention consists in cutting oft one side of the flange, and then passing the mutilated rail longitudinally through suitable rolls, for the purpose of laying down the remaining half of the flange until its plane coincides with that of the web, and at the same time breaking the head down ilat and elongating the bar. \Vhen the rail thus treated is drawn out to a uniform and required gage, itis out up into nail-plates.

To enable others skilled in the art to make and use my invention, I will now describe it by reference to the accompanying drawings, in which Figure l is a view of a rail or rail-section, indicatin where it is cut. Figs. 2 and 3 are the parts of the rail after being out. Fig. 4t is a diagram of a pair of rolls. Figs. 5, 6, and 7 are views of the rail after several passes through the rolls.

Like letlersof reference indicate like parts in each.

I take an old steel rail or section of rail or rail end, a, and cut off one flange on one side, as indicated by the line a. The separate piece I) thus made can be rolled out for various uses.

The mutilated rail 0 is passed lon gitudinally through the rolls d, as indicated in Fig. 4. The effect of the pass is to flatten down the llange part c more nearly into line with the web 0", and to break down thehead 6 partially, as well as to elongatethe rail. At each subsequent pass the rail is gradually reduced until it is finally brought to a uniform gage of the required thickness. It may then be out up into naitplates or otherwise utilized. Steel rails require to be so rolled that no part shall overlap and be laid down on any other part, for the reason that the plieated surfaces cannot be welded at the heat which may safely be given them. If two parts or edges of the bar overlap, a seam 0r crease is formed, which ruins that part of the finished plate or bar. To enable me to widen out the plate or sheet made from the rail, I use as much of the flange as is possible to lay down without plieation on some other part of the rail. If both sides of the flange were used, it is evident that one of them would be laid against the web, or that they would be laid together, that depending on the direction in which they were turned.

It will be noticed by the vertical plane lines shown in Fig. I that the reducing pressure of the rolls is only on single parts of the rail, and that no vertical plane bisects any two parts. The result is that the action of the rolls causes simply flattening and drawing of the rail, and no overlapping or plication of its parts.

\Vhere it is desired to obtain a plate or sheet of greater width than can be had from a simple longitudinal drawing, the short rail-section is, after the flattening of the flange, given one or more passes in a transverse direction, as is customary in sheet rolling.

The advantage of my invention consists in preserving a portion of the flange, which has heretofore been out off when old rails were used for similar purposes, to contribute to giving width and weight to the finished plate. This is very important, because the amount of stock in the cross section of rails is very small, and it is desirable to preserve as much of it as possible, especially in rolling out sheets which are subsequently to be cut transversely into nail-plates and similar articles.

of the desiredgage, substantially as and for to secure by Letters Patent, isthe purposes described. 10
