HENRY O. KRIETE, OF CHICAGO, ILLINOIS.
RAlL-ROLLlNG MILL.
SPECIFICATION forming part of Letters Patent No. 311,588, dated February 3, 1885.
(N0 mod 1.)
To (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, have invented certain new and usefulImprovements in Manufacture of Steel Rails, of which the following is a specitication, reference being had therein to the accompanying drawings.
My invention relates to improved means for treating steel ingots during their conversion into rails.
The object of the invention is to simplify the means and lessen the labor consequent upon the manipulation of the ingots during the several steps of the process to which they are subjected; and to the accomplishment of the above the invention consists of the novel devices and combination of devices, as will be described and claimed.
Reference will be made to the accompanying drawin'gs,in which Figurel is a diagram of part of the mechanism employed, showing the blooming rolls and table and a portion of intermediate rollers for transferring the ingots from the blooming-table to the finishing-rolls; Fig. 2,aviewof said rolls,this being a continuation of Fig. 1; Fig. 3, a diagram showing a continuation of Fig; 2, and illustrating the finishing-rolls; Fig. 4, a continuation of Fig. 3; Fig. 5, a continuation of Fig. 4, representing the cutting-saws; and Figs. 6 and 7 views in detail and on an enlarged scale of certain rolls and their arrangement with respect to one another.
Like letters refer to like parts in each view.
All parts not especially described and only referred to by letters in the course of the following description are of well-known construction, and no claim is made thereto.
In the drawings, A represents the bloom ing-rolls, three in number, one placed above the other, the upper and lower rolls being revolved in opposite directions with respect to the middle roll; 13, the blooming-table, and O rollers mounted therein. As will be well understood, the steel ingots are placed upon back between the middle and upper rolls, this operation being continued until the ingots are in proper condition to be treated by finishingrolls.
Duringtheabovedescribed operation it will be understood that because of the construction of the blooming-rolls the ingots are gradually shifted from one side of table 13' to the other. At the end of the operation they are, thus brought in line with two or more additional rollers, D, mounted in an extension of the blooming-table, said rollers always revolving in a forward direction. As the ingots are passed between the blooming-rolls for the last time, the rollers O are revolving in the same direction as rollers D, and the ingots are carried forward by said last-named rollers to rollers E F, suitably situated to receive them. Rollers F aresuitably mounted and act only as guides, being revolved by friction with the ingot, and are, as shown, placed alternately with respect to rollers E.
Secured to one end of the journal of each roller E is a bevel-gear, G, all of which mesh with bevels H, keyed to shaft I, and upon the opposite end of thejournal of the last of said rollers a bevel, K, is secured to mesh with one of a series of gears, L, secured to a shaft, M, which extends from this point to a point near the finishing-rolls N, Fig. 3. The bevels of shaft M mesh with bevels O, secured to the journals of plain rollers P, and with gears Q, which are keyed to the journals of rollers R, which are constructed, as shown, to accommodate the different thicknesses of the rail during its manipulation by the finishing-rolls.
Power is transmitted to shaft M and through it to the several rollers described from a suitable engine, S. Upon the opposite side of the finishing rolls a line of shafting, T, is mounted, which is drawn from a suitable engine, U, and is provided with a series of bevels, V,'while a shaft, WV, provided with bevels X is driven, through the medium of the intermediate gearing and counter-shafts shown, from pulley Y, Fig. 5.
It is desirable during the manipulation of the ingots by the finishing-rolls to provide rollers which may be reversed to reciprocate said ingots between said rolls, and, further, to have additional rollers always revolving in the same direction to transfer the finished rails to the cutting-saws, the two sets of rollers being so situated with respect to one another that the operation will be continuous, and the rails transferred immediately upon being finished. To accomplish this result, I employ rollers constructed and arranged as shown in Figs. 6 and 7. In these figures, Z are bevels which mesh with the bevels V of shaft T, said bevels being keyed to shafts A, while to the same shafts are keyed rollers B, which are reversible. r
Upon one shaft A is loosely mounted a sleeve, 0, Fig. 6, to which is secured a bevel, D, which meshes with one of the bevels X of shaft IN, thus continuously revolving said sleeve and the roller E mounted thereon in one direction. The next shaft Ais provided with the bevel Z and reversible roller B, but upon its opposite end is loosely mounted a roller, F, which being in line with roller E is revolved in but one direction by the friction I of the rail. I
Asshown in dotted lines in Fig. 3, through the medium of a shaft,G, and suitable gearing, the rollers upon both sides of the finishingin fact, this arrangement I consider desirable,
. although the two engines described should be The ingot in the condition in which it is displacedready for use in case of accident to charged from the blooming-table is fed by the r i l i l l rolls may be driven from the same engine,and, I l l l l I rollers deserihed through the finishing-rolls to taoting with an improved stopper, K,whereby the rails when out will all be of uniform length. No further reference is made to this stopper, for the reason that it is to be made the sub ject of a separate application.
I have not described in detail thedifferent gearings; nor do I wish to confine myself to any particular arrangement, as the same may be varied greatly without departing from the spirit of my invention.
hat I. claim is The combination, with finishing-rolls and a single set of reversible rolls upon each side thereof adapted to reciprocate the rail between such finishing-rolls, of a one-way set of rolls adapted to receive the finished rail and carry it from the finishing-rolls without i nterfering with the finishing process upon the next succeeding rail, as set forth.
In testimony whereof I afliX my signature in presence of two witnesses.
