MAX ROENSPIESS AND MATTHEW FLYN N, OF ST. JOSEPH, MISSOURI.

MACHINE FOR CURVING AND STRAIGHTENING STEEL RAILS.

SPECIFICATION forming part of Letters Patent No. 418,229, dated December 31, 1889.

Application filed June 24, 1889.

To aZZ whom it may concern.-

Be it known that we, MAX ROENSPIEss and MATTHEW FLYNN, citizens of the United States, residing at St. Joseph, in the county of Buchanan and State of Missouri, have invented certain new and useful Improvements in Machines for Curving and Straightening the Cold Steel Rails ordinarily used by Railways; and we 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, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Figure 1 is a perspective view of the machine. Fig. 2 is an end elevation of the machine. Fig. 3 is a cross-section of Fig. 2. Fig. 4 is a side elevation of the machine. Fig. 5 is an enlarged detail view of the channel-iron with nuts on. Fig. 6 is an enlarged detail view of one of the boxes through which the journal of the main roller passes. Fig. 7 is an enlarged detail view of the lower box of the main roller, and Fig. 8 is an enlarged detail View of one of the boxes for the small rollers.

Similar letters refer to similar parts throughout the several views.

Our invention consists of the following-described two principal parts: first, a frame constructed out of six-by-six-inch oak or other suitable timber, consisting of two sills a a, two uprights b 17, four horizontal posts 0 c c c, and two caps (1 cl; second, two iron rollers e e, turned out at o o o 1;, so as to ad Inita steel rail, and 'one iron roller f, also turned out so as to admit a rail at w 20. Each roller has a journal of suitable dimensions to run in iron. boxes. 1

On the upper end of the journal of roller f is a cog-wheel g, propelled by two cranks h h, Fig. 4, which are fastened to journal 1', and to which is fastened an endless screw 70. Af-

ter a steel rail is placed between the rollers enough pressure to bend the rail to the required curve, or to straighten a rail, is applied by means oftwo jack-screws Z Z, Fig. 2, which work in iron plates m m. These plates are each held in place by two rods an, which go through the plates and frame, and also by channel-irons 0 0, Fig. 3, which are bolted to the horizontal posts 0 c c c, the ends of the channel-irons to be rounded, with thread and nuts. Rods n n n n and channel-irons 0 0 0 0 also serve as truss-rodsto the frame. The endless screw 7c is held in position and gear by two iron rods 00 00, which go through the box p and boxes q q. The boxes q q are held down by two bolts 4" 1', which pass through the lower part of the boxes q q, just outside of the upper horizontal posts 0 0, nuts being on the ends of the bolts '2" r, and a plate of iron 8, which reaches across the bottoms of the upper horizontal posts 0 0. Boxes uuuu are of iron, constructed of suitable size for journals.

25 represents the lower box of the main roller f, and jjj represent the journals of the rollers.

Bolts y y in each box it, as shown in Fig. 8, are for the purpose of holding to in place on sill a. Bolts 2 z, Fig. 2, are for the purpose of holding upper and lower halves of box q together. J ack-screws ZZ bear against thejournal-boxes t and 19, and these journalboxes slide along channel-irons o 0.

The amount of pressure to be applied to secure the degree of curvature of rail desired will be shown by an indicator to be attached to one of the boxes q. After a rail is placed between the rollers at o and w and the neoessary pressure is applied, the rail is drawn through the machine by the revolving of endless screw 16 by cranks h h.

For convenience the machine may be put upon a rubble-car, which should be supplied with a threeinch roller on each end to help carry the Weight of rail.

From the foregoing description it will be seen that our invention does not accomplish the purpose for which it is intended by kinking a rail, but in its operation curves or straightens a rail of any weight truer, faster, and cheaper than any machine constructed for a similar purpose.

What we claim as our invention, and desire to secure by Letters Patent, is-

1. The combination of frame consisting of sills a a, uprights b 1;, horizontal posts a c c 0, caps d d, with rollers e e and f, channel-irons 0 0 0 o, cog-wheel g, endless screw is, jackscrews Z Z, journals '0' and j jj, boxes pt q q u u u u, plates m m and s, rods a: as and n n n n,

bolts r r, y y, and z z, and cranks h h, for the ;a a, uprights b b, and caps d d, substantially 1o purpose specified, substantially as described. as described, for the purpose specified.

2. The combination of rollers e c, turned In testimonywhereof weaffixour signatures out at o '0 v o, and roller f, turned out at w in presence of two Witnesses.
