HENRY C. KRIETE, OF CHICAGO, ILLINOIS.

RAIL-CUTTING DEVICE.

SPECIFICATION forming part. of Letters Patent No. 311,589, dated February 3. 1885.

Application filed March 25. 1884.

T0 all whom, it may concern:

Be it known that I, HENRY C. KRIETE, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Rail-Cutting Devices, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improved mechanism to be used in connection with steel ingots duriiigtheir conversion into steel rails. After passing through the blooming and iinishing rolls the ingot is formed iiito oiie long rail, usually of about one hundred and twenty feet inlengt-h, and it becomes necessary to cut such rail into several shorter ones, generallyT into four of thirty feet each, and it is esseii tial that all the sections should be of a uniform length.

The object of this invention is to provide suitable mechanism by the use ot' which all the sections of rail will be of uniform length, provision being made for the contraction of the metal. It will be understood that the hotter the rail the more the contraction thereof, and it consequently follows that the first section cut from the long rail will contract more than those subsequently out, and that such first cut section would be shorter than the subsequent ones if some means were not employed to avoid such difficulty.

For the accomplishment of this end the invention consists of a stopper against which the end of the rail is forced and rests during the operation of the saw, said stopper being provided with a suitable number ot' projec tions each of a different thickness. When the first section is to be cut the thinnest or leastiprominent projection is presented and the rail out at such a length that upon coiitraction it will be the proper length-say thirty feet. The stopper being thus turned the next projection is presented and a slightly shorter rail cut, Ste.

Reference will be made to the accoinpanying drawings, in which Figure l is a plan view ofthe stopper, showing part ofthe rolling mechanism; Fig. 2, a side view thereof, and Fig. 3 an end view of the saine.

(No model.)

Like letters refer to like parts in each view.

A represents the stopper, which is mounted upon a shaft, B, in line with feed-rollers C, upon which the rail to be operated upon is moved. The stopper, as herein shown, is constructed for use where it is desired to divide the rail into four sections, and it consists of a hub from which radiate three arms, a, b, and c, each provided with a projection, ab c. Projection c is of such a thickness and so placed in relation to the cutting mechanism y that the section formed when the rail contacts therewith will be exactly thirty feet after contraction, while as the rail grows cooler, it being necessary to cut a shorter sect-ion, the contraction being less, the projections b c are successively presented, the projection b being` ot' a slightly greater thickness than a, and c being thicker than Z1.

Keyed to shaft B is a cog, d, which meshes with a cog, e, mounted on a stud, and which in its turn meshes with a cog, f. Cogfis keyed to a shalt, g, to the opposite end of which is keyed a bevelgeai, lt, which meshes with a similar gear, t', keyed to one end of a shaft, 7c, upon the opposite end of which is mounted aliandewheel, l. By this connection it will be seen that the stopper may be revolved to present the different projections in line with the rail by any one operating said hand-wheel. Vheu the rail has been cut it will be understood that the stopper may be turned to allow it to pass between the arms thereof.

\Vhat I claim isl. In a device for cutting rails, the combination, with suitable cutting mechanism, of a stopper provided with a series of projections ot' different thicknesses, as and for the purpose set forth.

2. The stopper A, constructed as described, in combination with means foi' operating it, as and for the purpose set forth.

In testimony whereof l affix my signature in presence of two witnesses.

HENRY C. KRIETE.
