UNIVERSAL ROLLING-MILL.

SECIFIOATION forming part of Letters Patent No. 684,658, dated October 15, 1901,

Application tiled November 21, 1900. Seria] No. 37,255. (No model.)

To all whom it may concern:

Bc it known that I, PETER M. IVEBER, a citizen of the United States of America, residing at Homestead, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Im provements in Universal Rollingdtlills, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in rolling-mills, and is an improvement upon my Patent No. 645,409, bearing date of March 13, 1900.

The present invention has for its object to construct a universal mill wherein the horizontal and vertical rolls are adjustable and provide means whereby the horizontal will impart or communicate a rotary movement to the vertical rolls; furthermore,provide means whereby the horizontal rolls will be connected at all times to the vertical rolls irrespective to any adjustment of said rolls.

In my former patent I have shown a pair of horizontal and vertical rolls; but the vertical rolls were driven by the f rictional engagement of the blank to be rolled, and I find that a great advantage is obtained by connecting means to the horizontal rolls that will impart a constant rotary movement to the vertical rolls.

Another object of my present invention is to provide means whereby a perfectly smooth beam or the like may be rolled with less friction than heretofore and preventing any liability of the vertical rolls stopping in case a great pressure is bearing against them when the same are driven by frictional engagement.

Ihave found by the use of myimprovements there will be less wear and tear of the working parts of the machine. Consequently the lifetime of the same will beprolonged in this manner.

W'ith the above and other objects in view the invention consists in the novel combination and arrangement of parts to be hereinafter more fully described, and specifically pointed out in the claims.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, and wherefin like numerals of reference indicate correspending parts throughout the several views, in which- Figure l is a side elevation of my improved universal mill. Fig. 2 is a front view thereof. Fig. 3 is a side elevation of thc vertical and horizontal rolls, lthe latter being partially broken away. Fig 4 is an underneath plan view of the vertical roll.

In the drawings, the reference-nunieral l represents the housings, 2 the upper horizontal roll, and 3 the lower horizontal roll, the latter roll being provided with cog-wheels 4 on each side thereof, said cog-wheels being adapted to mesh with the cogs 5 of the vertical rolls 6, said cogs 5 being arranged on the under face of said rolls 6 and extending radially around the periphery of said rolls, said horizontal and vertical rolls being adjustable for the purpose of rolling different thicknesses of beams.

The operation of my improved rolling-mill is as follows: The horizontal rolls 2 and 3 being driven in the usual and well-known manner, the lower roll 3, carrying with it the c0g wheels 4, will communicate a direct rotary movement to the vertical roll 6, the latter being driven in unison with the rolls 2 and 3 as the blank is formed between the horizontal and vertical rolls.

The many advantages obtained by the use of my improvements willbe readily apparent from the foregoing description and by referring to the accompanying drawings.

Particular attention is directed to the fact that the arrangement as herein described may be attached to the upper roll instead of the lower one and may be operated in the same manner; furthermore, that other means may be employed carried by one or both of the horizontal rolls to communicate a direct rotary movement to the vertical rolls and that other changes may be made in the details of construction without departing from the general spirit of my invention, and the vertical rolls are adjusted inwardly and outwardly, as shown in the drawings.

In the drawings of my prior patent, as well as the present invention, I have shown the vertical rolls constructed in a plain cylin- IOO drieal form; but I do not wish to limit myself to this construction, as the same may be mountedV upon bearings or shafts when desired. It Will also be noted that the horizontal rolls maybe adjusted upwardly and downwardly, either one roll or the other roll, as may be found most expedient.

Having thus fully described. my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a universal rolling-mill, the combination of horizontal adjustable rolls, vertical adjustable rolls, oog-wheels arranged to one of said horizontal adjustable rolls, cogs arranged upon one end of each of the said vertical adjustable rolls to comm unieate a rotary
