Application fil d September 22,189 9. Serial No. 731,284 (No modeL) 1'0 (ultra/tom it'mctj concern;

Be it known that I, PETER M. \VEBER, a

citizen of the United States of America, residvented certain new and useful'lmprovements in Universal Rolling-Mills, of which the following is a specification, reference being had 1 r vertical sectional view of one of the bearings therein to the accompanying drawings.

This invention relates to certain new and.

useful improvements in rolling-mills for structural iron. I

The herein described invention relates more particularly to universal mills, and in order to clearly illustrate my invention I have shown the apparatus particularly constructed for rolling I-beams. r

The invention broadly consists of three separate and distinct sets of rol1snamely,

cogging-rclls, universal rolls, and finishingrolls.

The invention primarily has for its object the provision of novel means whereby the ingots after passing through the cogging-rolls may be of such size,'thickne se, and form that will admit of art easy and free manipulation in the universal rolls, that will further shape the I-beams to certaindimensions, that when entering the finishing-rolls the beams will be further reduced to the exact dimensions required, the rolls being arranged in such a manner that will allow the feet to extend outwardly and finished to the required thicksmooth, with true and accurate contourlines.

ness and strength, obviating the objection able feature ofa fin forming'upon the feet of the beams, and finishing the latter perfectly The invention also consists of the novel 8 form of mechanism for the adjustment of the universal-rolls and the peculiar construction of the same that will be hereinafter more particularly described, and specifically pointed 11 like numerals of reference indicate correponding parts throughout the several views,

Referring to' the drawings by referencenumerals, 1 indicates the housings of the cogging-rolls.

2 represents the upper and 3 the lower cogging-roll. The said rolls are constructed to receive the ingot at the passes 4:, t, 9, and 9, the rolls being provided with collars 5 5 5 5, having interposed between said collars a pair of collars 6, which are approximately V- shaped in cross-section andone of which being of greater size than the other. Upon the other side of the said collar 5 are interposed similar collars 7, having arranged between said collars enlarged collars 8, having tapering'sides and forming the passes 9 between the upper' and lower rolls for forming the I- Suitable bearings 10 are provided at the ends of the rolls, being journaled in the housings in the well-known manner. The reference-numeral 19 indicates the housings of the universal rolls, in said housings being mounted and suitably journaled horizontal rolls 20, said horizontal rolls 20 having beveled sides 21, extending to a shaft 22. Vertical rolls 23 are arranged to operate upon roller-bearings 24:, said vertical rolls and roller-bearings being secured in slidable bearings 25 25. These slidable bearings are each arranged to operate in thecasings 26 26. 27 indicates ascrew-threaded shaft which is adapted to extend through the casing 26 and connected at its inner end, as at 28", to the slidable bearing 25. At the end of the easing 26 is mounted a miter-gear 28, which is arranged upon the screw-threaded shaft 27,

said miter-gear 28 being set vertically, and is adapted to mesh with a miter-gear 29, car- I rying a shaft 30, which is suitably mounted in brackets 31, which are rigidly secured to the said housings. At the upper end of the said shaft 30iis provided a miter-gear 32. This miter-gear meshes with a miter-gear 33, carrying a horizontal shaft 34. At the end of said shaft a corresponding miter-gear 33 is provided to operate the miter-gear 32, the latter being secured to the shaft 30, which is arranged in brackets 31" and rigidly secured to the side of the housings. .At the lower end of the said shaft 30 is secured a miter-gear 29, said miter-gear 29 meshing with a vertically-mounted miter-gear 28, this miter-gear 28 being mounted upon the screwthreaded shaft 27 and is connected at 27 to the slidable bearings 25 and extends through the casing 26.

The reference-numeral 35 represents vertically-adjustable bearings arranged in the housings, in which are mounted the horizontal rolls, these vertically-adjustable bearings being operated by means of screw-threaded shafts 36, carrying cog-wheels 37, the latter being operated by and through the medium of cog-racks 38, said cog-racks 38 being preferably operated in unison, although they may be independently operated, if desired.

The reference-numeral 39 indicates the housings of the finishing-rolls, in which are mounted the upper finishing-roll 40 and the lower finishing-roll 41. After the I-beam leaves the universal mill it has to be passed between the pass 42,. formed between said rolls, thence through the pass 43, and finally through the pass 44, centrally between the rolls 4L0 and 41, where the beam is finishedto the dimension desired.

Particular attention is directed to the universal rolls, the ordinary rolls in this set operating in unison and operating in opposite directions, either inwardlyor outwardly, as desired. The said vertical rolls engage and operate the lower face of the I-beam, and finish the same, thereby dispensing with the pe culiar-shaped rolls that were heretofore employed for this purpose and in which fins are often formed upon the foot or base portion of the I-bea-m. By the use of my improved rolling-mill this objectionable feature is entirely obviated. I

Further-attention is called to the mounting of the vertical rolls upon the roller-bearings, the ordinary bearings for the vertical rolls being entirely dispensed with, thereby allowing and permitting the said vertical rolls to be adjusted to such a point that will be in close proximity with the beveled sides 21 of the rolls 20, and thereby allowing the vertical rolls to operate in the contracted space-that could otherwise not be obtained.

It will be noted that various shapes of I- beams may be rolled in the manner that I have heretofore described and that other structural iron maybe manufactured in like manner; furthermore, that various changes may be made in the details of construction collar at each side of the first-mentioned colof my improved rolling-mill without depart.-

ing from the general spirit of my invention.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is I journaled in each pair of said bearings and each adjusted toward one another by the said bearings, means for adjusting the said bearings, a casing secured to each side of said housing and arranged between each pair of adjustable bearings, a longitudinally-operating bearing arranged in each of the said casings and provided on their inner face with a semicircular recess in which is mounted a series of roller-bearings, a retaining-plate se cured to the inner end of said longitudinallyoperating bearings and provided with a rectangular opening, a vertical roll mounted in each of the said recesses, frictionally engaging said roller bearings, projecting partly. through the said opening and retained in position by said plate, and means connected to each of said longitudinally-operating bearings .9 5 adapted to operate the same simultaneously, substantially as described.

2. In a universal rolling-mill, the combination with a pair of cogging-rolls, a pair of vertically-adjustable universal rolls and a pair of simultaneously-operating longitudinal bearin gs arranged in relation to said universal rolls, of a pair of finishing-rolls provided between the same with a series of horizontally- 7 arranged passes for finishing I-beams and preventinga fin forming upon the feet thereof, said passes formed by providing each of the said rolls at the first pass with a horizontally alining collar. with tapering sides, an alining .19 lar and provided'with straight sides and so 7 arranged as to form a horizontal portion upon the rolls between the collars, providing the upper of said rolls at the second pass with a V collar having each side thereof tapering and :15 terminating in an annular shoulder and further providing said roll with a horizontal por tion at the side of each shoulder; providing the lower of said rolls at .the second pass with a collar in horizontal alinement with the collar of the upper roll and having its sides tapering and terminating in a horizontal portion in alinement with the annular shoulders of the upper collar, further providing said lower roll at the second pass at the end of I25 each of the horizontal portions with a collar of greater diameter than the alining collar and which operate at the side of each of the annular shoulders of the upper roll; providing the lower of said rolls at the third pass with a collar having each side tapering and terminating in an annular shoulder and further providing said roll with ahorizontal portion at the side of each of the said collars, l
