ROD-MILL.

SPECIFICATION forming part of Letters Patent No. 451,673, dated May 5, 1891.

Application filed December 26, 1890. Serial No. 375,840. (No model.) v

To all whom, it may concern."

Be it known that I, IRVING A. KILMEE, a citizen of the United States, residing at Newburg, in the county of Orange, State of New York, have invented certain new and useful Improvements in RodsMills, of which the follow-' ing is a specification, reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in rod-mills; and it has for its objects, among others, to so arrange the parts or elements comprising the plant that the necessity of providing a floor over one or more of the shafts of the rolls for the accommodation of the workmen is avoided.

It has for a further object the provision of improved means for imparting power to the several shafts.

A further object is the economy of space by bringing the dilferent shafts and trains into as close proximity to each otheras consistent with good results. I so arrange the parts that all of the repeaters orguides will be upon one side of the shaft, so that the said shaft need not be protected or covered. The power is imparted to the different shafts from an engine or engines with pulleys and belts compactly arranged.

Other objects and advantages of the invention will hereinafter appear, and the novel feaures thereof will be specifically defined by the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, forms a part of this specification, and in which is shown a plan of my invention.

Referring now to the details of the drawings by letter, A designates the main operating shaft, which is journaled in suitable bearings and arranged to be driven from any suit able motor, either a single or double engine beingshown as provided with one crank a,

although there may be another upon the other end of the said shaft. The plant comprises four series or trains of rolls consisting of a billet-train B, a side train 0, and two finishing-trains D and E. The finishing-trains are arranged with one shaft extended beyond the other and the two located relatively between the billet and side train. The rolls of theseveral trains are preferably, though not necessarily, located outside of the rolls of the adjacent trains, so as to avoid tangling of the rod by'reason of slack or surplus and to provide for the overfeeding of the rod without danger of stopping of the mill or injury to the rolls or rod. The finishing-trains are arranged within the limit of the billet. and side trains, but beyond the ends of the shafts thereof, so that all of tlie curved guides or repeaters F shall be upon one side of the mill, thus avoiding the necessity of a flooring or other protector for the shafts, which would be necessary if the trains were so arranged that the repeaters were upon the other side of the shaft. These curved guides or repeaters may be of any of the well-known forms of construction and avoid the necessity of catchers at these points.

It may sometimes be found desirable to so arrange the trains that the workmen may be arranged with catchers where the rod emerges from the rolls in a rectangular cross-section and where the flooring over the shaft is not objectionable, in which case I arrange the final finishing-train as indicated in dotted lines in the drawings; but the former arrangement is much preferred.

On the main shaft I arrange the four pulleys G, H, I, and J, the three former of sub-' stantially the same size, while the latter is much smaller. On the shafts of the several trains I arrange the pulleys M,N, O, andP, that on the shaft of the billet-train being the larger and that on the side train smaller, and those on the shafts of the two sections of the finishing-train being still smaller than that of the side train, at. (1 preferably of varying size, as shown, so that the different trains will be run with different velocities, the shaft of the billet-train revolving the slowest and that of the finishing-train the fastest, so as to prevent slack between the trains.

Suitable belts K are provided for communicating power from the main shaft to the various train-shafts, as indicated by dotted lines.

The initial roll of the side train being arranged outside the final roll of the billet-trainpermits me to use a straight guide L from the billet-train, and a catcher is employed at this point to guide the rod to the initial roll of the sidetrain.

\Vhat I claim as new is- 1. A plant for rolling billets to rods, comprising a hillettrain, a side train, and a finishing-train in sections, arranged between the side and billet trains,with the rolls of both sections beyond the final roll of the side train, as set forth.

2. A plant for rolling billets to rods, comprising a billet-train, aside train in proximity thereto, with its initial roll beyond the final roll of the billettrain, and an intermediate finishing-train in sections, with the rolls of each section beyond those of the adjaeentsection and the initial roll of the first section be yond the final roll of the side train, as set forth.

A plant for rolling billets to rods, comprising; a billet-train, a side train, and a fin ishing-train with the repeaters all upon one side of the train, as set forth.

4. In a rod-mill plant, a side train, abillettrain, and an intermediate finishing-train in sections, with the rolls of the several trains beyond the limit of those of their next adjacent train, pulleys on the several shafts, and con neotions with the main actuating-shaft, whereby different speeds are given the shafts of the several trains, as set forth.

5. In a rod-mill plant, a billet-train, a side train in close proximity thereto, and an intermediate finishing-train in sections, the shafts of the sections extended one past the other and the rolls of the several trains arranged with their initial and final rolls beyond the limits of those upon either side thereof, substantially as specified.

(5. In a rod-mill plant, the series of rolls arranged with repeaters, all extending in one direction from the initial roll of the billettrain to the final roll of the finishing-train, whereby a protector over the shaft extending from the final roll of the billettrain to the initial roll of the finishing-train is obviated. as set forth.

In testimony whereof I atfix my signatu re in presence of two witnesses.

IRVING A. KILMER.
