IMPROVEMENT INAMAHINES FOR SLITTING RAILROAD-RAILS.

Specification forming part of Letters Patent No. 180,373, dated July 25, 1876; application filed May 26, 1876.

To all whom it may concern Y Be it known that I, JACOB REESE, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Machines for Slitting Railroad-Rails; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompaying drawing, forming part of this` specification, in which- Figure l is an elevation of a machine em- Fig. 2 is a Ilongitudinal vertical section. Fig. 3 is a horizontal section 011 the line x fr, Fig. l; Figs. 4, 5, 6, and '7, diagrams showing the manner in which rails may be cut for various purposes.

Like-letters refer to like parts wherever they occur. i

My invention relates to machinery for slithousingscrews (not shown) may be used for adjusting the bearings. C representsv the shafts or rolls, which carry the cutters. The

shafts are turned up with the journals c c', and

with one or more collars, d, to form a shoulder or bearing for one of the detachable cutters, the distance of d from the nearest journal being determined by the length of the shaft, and the amount of adjustment required for the cutters. c e are annular cutting-disks or cutters slipped upon shaft (l, andseparated by a detachable collar, f, the whole being secured by a nut or threaded collar, g, which engages with a thread formed on the shaft C. The annular cutting-disks c e are beveled upon their peripheries, and are so arranged upon the shaft C that when the rolls are placed in the housings the cutting-edges of the disks upon the upper roll, andthe cutting-edges of the corresponding disks upon the lower roll, will be in the same vertical plane, so that the rail will be divided by a chisel-cutvfrom two sides. Howover the cutting-disks are adjusted, the relative arrangement of the corresponding cutters of the two rolls must be preserved,as before 'specietu In order to preserve the relations of the journal, and to steady the roll, a loose .journal-collar, h, is slipped upon the journal,

and bears against the shoulderof shaft G. The widthof detachablecollar f may besuch as to adjust thecutting-disks for a small or low rail, and when high rails or wider webs are to be cut annular washers may be interposed, or, if preferred, collars ot' different widths may be used. The fixed collar or collars d may be cast or turned up with the roll, or may be shrunk on the shaft, as preferred.

In slitting rails the tendency of the ilange and head-pieces, so cut, is to curve outward from the web. (See diagram.) To prevent this I make use ofthe adjustable guide-bars, so as to cause the pieces when cut to pass out of the rolls in a straight condition ready for'subsequent use. Supported upon crossbars E, secured to the housings, is the above-mentioned rail-guide, composed of two adjustable plates, k Z, the one, k, grooved to receive the head of the rail, and the other, l, plain to accord with the base or flange. Either or both of the plates may be adjusted at pleasure, or according to the size of the rail, by means of the bolts m, which pass through slots in the cross-bars E. The several parts composing the roll being constructed substantially as specified, one cutter, c, is slipped upon shaft C, and passed 11p to collar d. A loose collar, corresponding to the width of the web of the rail to be slit, or if a collar of such width is not at hand, then acollar of less width, together with' a sufficient number of washers to make up the difference,

is next put on the shaft, after which the other. cutting-disk is added, and the whole secured by the threaded collar g.

Two' such cutting-rolls having-been adjusted in the housings the position of the rail-guide with relation to the cutters is regulated by sliding the plates on the cross-bars E, after which the guide is fixed by the bolts m and nuts. Power being applied to 'the rolls, land the rail properly heated and placed in the guides, the collar f will bite upon the web and cause the rail to travel through the rolls between the cutters, when, if the several adj ustment-s specified have been carefully made,

the lines of cut will be continuations of the outline ot'eaeh section ofthe rail, (see diagram, Fig. 5,) thus leaving no projections, as shown in diagram, Fig. 5, and avoiding laps or seams in the nished bars.

The adjustment ofthe cutters so as to slit the rail into three sections, head, web, and flange, as shown in diagram, Fig. 5, is that I usually employ in producing bars, hoops, baleties, &c.; but it' it is desired to cut off the head ofthe rail only, so as to leave the web and ange in one piece, (see diagram, Fig. 7,) to be thereafter rolled into T-iron, this may be done by loosening collar g, and removing the cutter nearest the plain guide-plate; orif the flange of the rail only is to be cutoff, (see diagram, Fig. 6,) so as to leave the Web and head connected, in which condition it Will be found adapted to be rolled into plow-beams and similar articles, this can be done by removing the cutter nearest the grooved guide-plate.

From the foregoingvdescription it is evident that, in addition to the advantages specified over those machines wherein the cutter and roll are formed in one, by my improved construction the cutters may be adjusted to cut portions only of the rail, leaving itin various forms adapted to utilization in Well-known manufactures. While this may not seem of special advantage in using up rails made ot' weldable metal, its great advantage is apparent in the utilization of-old Bessemer steel rails, rail-ends, Snc., which are accumulating at the works and elsewhere, which it is very difficult, if not impossible, to weld, and which,

it' reworked to advantage, must be reworked JACOB REESE.
