ROLLER FOR RAILWAY-BARS.

Specification of Letters Patent No. 20,452, dated June 1, 1858.

T 0 all whom it may concern:

Be it known that we, Eow. W. STEPHENS and RICHARD JENKINS, of the city of Covington, in the county of Kenton and State of Kentucky, have invented a new and useful Combined Arrangement of Rollers for Making tailroad-Rails; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, and made to form part of this specification.

Similar letters and figures refer to like parts of the improvement.

The object of our improvement is to construct an opened railroad T rail, as represented in its transverse sectional view in Figure 3, and employ such means as will enable us to close the walls (f, f,) any distance apart for making the space (9,) between the walls, any required width without springing, or crooking the rail in the process of making it, and the nature of our improvement consists in the combined arrangement of a pair of vertical rollers with the horizontal rollers and furnished with grooves to suit the required external form of the rail, which vertical rollers will be employed to close the walls of the rail any required distance apart, as the rail passes the last time through and from the horizontal rollers. The object in thus combining and arranging the rollers is to keep the rail in a vertical position or its top or bot tom up or down when being finished to prevent it from springing, which itwould, if it was passed from the horizontal rollers on its side, as the rail with the shape given to it, will more readily spring when being worked on its side, than when in a vertical position with its top or bottom uppermost.

To enable others skilled in the art to make and use our improvement we will proceed to describe its construction and operation by referring direct to the accompanying dravings of which- Fig. 1, is a side elevation of the horizontal rollers. Fig. 2 is an end view, and Fig. 3, is a transverse sectional view of an opened T-rail, made with the combined arrangement of the rollers as represented.

We use three horizontal rollers (A, B,

and C,) (though but two could be used if desired) which will be placed in suitable housing or frame work, and operated with gearing as usual combined with the vertical finishing rollers (d, (L) which will likewise receive their motion with a system of gearing taken from the horizontal rollers or otherwise and the motion at the surface of both horizontal and vertical rollers will be geared to run the same speed.

The horizontal rollers are furnished with grooves 10, 11, 12, 13, and 1%, and tongues 15, 16, 17, 18, and 19, which form the openings or grooves 1, 2. 3, 4-, and 5, between the lower top and middle rollers as represented in Fig. 1.

The bar from which the rail is made, is first passed into the groove 1, then back through the groove 2-, then through the groove .3, then back through the groove 4, then through the groove 5, which last groove makes the rail in its transverse section in the form of an ordinary U rail and as it passes through the groove 5 the rail is made to pass between the vertical rollers (Z, (Z, and into the groves 2020, which are more fully represented, in Fig. 1, with dotted lines, and by passing the rail between the vertical rollers a, (Z, it gives it the form represented in Fig. 3, and by adjusting the vertical rollers together or apart, the space 9, between the walls (f, f,) of the rail, can be made any required width, and if ever desired to make the rail with its walls (f, f,) pressed or welded together, the vertical rollers d (I, are removed, and the rail is passed through the finishing grooves (3, and '7, in the horizontal rollers which will form a hollow T rail.

hat we claim as our improvement and desire to secure by Letters Patent is The combined arrangement substantially as represented, of the horizontal and vertical rollers (A, B, C,) and (cl, 4,) when furnished with grooves as represented substantially for the purpose mentioned, in the foregoing specification, and represented in the accompanying d awings.
