To all whom it wtayconcernl- Be it known that I, RAYMOND DEE YORK,

of Portsmouth, Scioto county, Ohio, have invented a new and useful Improvement in Universal Rolling-Mills, of which the following is a specification.

I will describe a millembodying the im-v provement-andthenpoint out the novel fea-.

tures in the claims.

In the accompanying drawings, Figure l is partly a front elevation and partlya vertical section of a universal mill embodying the improvement and especially'constructed for a blooming-mill. Fig. 2 is part-1y a side eleration and partly a vertical section of this mill. Fig. 3 is partly a plan and partly a horizontal sectionof the mill. Fig. 4 is a horizontal section at the plane of the line 4, in Fig. 2, illustrating the lower bearing for an uprightroll comprised in the mill. Fig. 5

is a side elevation of parts shown in Fig. 4:

the plane of this figure being the same as that of Fig. 2. Fig. 6 is an elevation of the parts shown in Fig. 5, this elevation being in a vertical plane which is indicated by the arrow 6 in Fig. 4 and is at right angles to the vertical plane of Fig. 5. Fig. 7 is partly an elevation and partlya vertical section of the upper bearing for-the same upright roll and parts related thereto, which, except'for the fact that this view is partly in section, corresponds in plane of elevation with-Fig. 5.

Fig. 5 is a horizontal section at. the plane of the dotted line 8 in Fig. 7. Fig.9 is an ele vation of certain parts and a transverse section of a shaft which is combined with said parts, all being in a plane indicated by the arrow 9 in Fig. 7. Fig. 10'is partly an elevation and partly a section of another upright roll with bearings therefor and other related parts, the plane of thisview being, parallel with the planes of the front and rearof the machine. Fig. 11 is an elevation of the parts shown in Fig. 10 and is at one of the sides of the mill.

section at the plane of the line 12 in Fig. 10. Figs.,1, 2, and 3 are drawn toone' scale, and Figs. 4, 5, 6, 7, 8, 9, 10, 11, and 12 are all on' another scale, which is considerably larger than the scale of Figs. 1, 2, and 3.

Fig. 12 is a horizontal- B B are horizontal rolls arranged one above the other and provided with a number of passes. Thelower rollB is shown as being journaled'in fixed'bearings, whereas the upper roll B is journaledin bearing-boxes b, whichare capable of moving verticallyin housings a of the side framesa a Each of thebearin-g boxes b .has connected with its lower portion downwardly-extendingrods b,

which at their lower extremities are secured to a yoke 12 This yoke b is connected with an engine 0. Preferably this will be a hydraulic engine, and its plunger cwill be directly connected withihe yoke 12*. Upward adjustments of the upper roll B are effected by the two engines 0, and these engines serve to support this roll. Downward-adjustments of the upper roll cannot, of course, occur until permitted by the engines 0. facilitated by screws D, cooperating With'the bearing-boxes b. There is one of these screws for each of the bearing-boxes b. These screws also prevent the upper roll frombeingmoved upwardly, except when it is -to be. adjusted into a new position. The screws D coact with nuts d, arranged in the upper portions of the side frames a (1 The stems or shanks d of the screws D extend into worm gearwheels (1 supported'by brackets 01, erected upon the tops of 'the side frames a a The engagement of. the stems or shanks d of the screws D, with the worm gear-wheels (Z is of such character as to permit'ofan inde pendent vertical movement of the screws without any independent rotary movement of the worm gear-wheels. The worm-wheels d engage with worms d3, secured to shafts,

d d journaled in the brackets. af These shafts d? d are arranged in line and are connected at adjacentends by means of a coupling 01 which will permit of their disconnection and rotary adjustment into different relations to secure a proper adjustment of the screws D relatively to each other, and consequently of the upper roll B The shafts d d may be d riven by an engine applied to either of these shaftsas, for instance, to the shaft (l -and such engine may advantageously be an electromagnetic engine or motor.

The rolls B B are shown as having three

passes

1, 2, and 3. The pass 1 is of ordinary configuration and is adapted to produce a reduced slab or ingot having parallel top and bottom and sides bulging outwardly to points about midway of the top and bottom. The pass 2 comprises a central cylindric portion 11 Atthe sides of this centralcylindric portion I) are two adjacent collar or flange-like portions 1)", having adjacent sides which are inclined so as to diverge toward their peripheries. At the other sides of the collars or flange-like portions are cylindric portions b which may be of approximately the same diameter as the central cylindric portion b although this is not essential. Beyond the cylindric portions 17 are collar or flange-like portions 19 The adjacent sides of each pair of collar or flange-like portions 1)" b are inclined so as to diverge toward their peripheries. The collar or flange-like portions Z) of the two rolls B B are shown as of such diametrical size that when the rolls are properly adjusted those of each roll contact with those of the other; but this is not an essential feature. The collar or flangelike portions Z) are diametrically smaller.

Hence a space is left between those portions of the two rolls. It will be seen that this pass 2 is adapted to transform the reduced ingot or slab resulting from the operation of pass 1 into a blank or partly-formed I-beam or girder having, as usual, flange-like portions, but having in addition to these flangelike portions a web which is thickened longitudinally along its middle portion on both sides. The pass 3 has a central cylindric portion b which is quite large diametrically. On each side of this cylindric portion are cyliudric portions 5 which are diametrically smaller. Beyond one of the cylindric portions 12 is one of the collar or flange-like portions b already mentioned, and beyond the other cylindrie portion b is a collar or flangelike portion b which not only forms part of pass 3, but also part of pass 1. The collar or flange-like portion h is shown as of the same diametrical size as the collar or flange-like portion 12 The sides of the cylindric portion b and adjacent sides of the collar or flange-like portion 19 are inclined so as to diverge toward their peripheries. The blank produced by pass 2 facilitates the subsequent shaping by pass 3. In the latteroperation the central thickened portion of the blank produced by pass 2 is thinned down to the proper dimension, and this results in widening the web and forcing the flanges of the I-beam or girder apart to the proper distance for a finished I-beam or girder blank. In Fig. 2 the shape of this blank and its position in pass 3 is indicated. The strain exerted on the metal in passes 2 and 3 is materially less, especially at the flanges of the I-beam or girder blank, by reason of the fact that in pass 2 there is left in the blank a thickened central portion, which is the principal part operated upon in pass 3.

E E E E designate upright rolls which for convenience may hereinafter be designated as long upright rolls. F E (see Fig.

are other upright rolls which for conveniencemay hereinafter be referred to asshort upright rolls, which are located in proximity to the rolls E E and coact with the rolls E E upon the blank when the blank is being worked on pass 2. The long upright rolls are journaled in lower bearings, which are illustrated in detail by Figs 4, 5, and 6, and in upper bearings,which are illustrated in detail by Figs. 7, 8, and 9. The lower bearing of each of the rolls E E 13 E consists of a block 6, having a recess 6 in which is fitted a bearing-box c madeslightly shorter, so as to provide for horizontal adjustment by means ofa screw 6, engaging with a nut 6 secured in a recess in the block 6, a check-nut being fitted to the screw c to secure it in position. Any suitable antifriction metal e may be used to advantage in the bearingbox c Opposite the bearing-box e a cap a is fitted to the lower journal and is secured by bolts and nuts 6" to the block 6. In the block e are two nuts e c, with which engage screws E These nuts are secured in recesses 6 Opposite the interiors of these nuts the cap a is provided with holes 6 for the passage of the screws E The nuts 6 e are restrained from rotary movement by having spur-teeth 6 formed upon their exteriors and combined with toothed segments a, which are bolted to the blocks 6. Thus facility is afforded for releasing either nut and adjusting it rotarily to secure a proper operation of the screws E The object of adjusting the rolls horizontally is to enable their axes to be alined or broughtinto the same horizontal plane. One pair of screws E coacts with the lower bearings of the two long rolls E E and another pair of these screws coacts with the lower bearings of the long rolls E E. To enable the screws E to thus operate for adjusting opposite long rolls, they must be reversely threaded where they engage with the lower bearings for the opposite rolls.

The upper bearing of each of the rolls E E E E is constructed, as shown in the drawings, like the lower bearing, and each upper bearing consists of a block 3, having a recess .9 made slightly shorter, so as to provide for the horizontal adjustment by means of a screw .9 engaging with a nut 5 secured in a recess in the block 8 a check-nut 3 being fitted to the screw 8 to secure it in position. Any suitable antifriction metal 3 may be used to advantage in the bearing-box s frames a a As the bevel gear-wheels e Opposite the bearing-box s a cap 8 is fitted to the lower journal and is secured by bolts and nuts 8 to the block 8. In the block 8 ago two nuts 3 3 with which engage screws S Opposite the interiors of these nutsa cap 5 is provided with holes sfor the passage of screws S The nuts 5 s are restrained from rotary movement by having spur-teeth 5 formed upon their exteriors and combined with toothed segments 5, which are bolted to theblock s. Thus, as in'the lower bearing, facility is afforded for releasing either nut and adjusting it to secure a proper operation of the screws S The screws E S are journaled in bearings provided in the side frames a o The screws,

E haveaffixed to them worm gear-wheels 6 These worm gear-wheels for each pair of the screws E engage with a worm G, affixed to an upright shaft G, which is journaled in brackets fastened to one of the side frames of the mill. The screws S have affixed to them worm gear-wheels 5 These worm gear-wheels for each pair of screws S engage with a worm G affixed to the shaft G. The

upper ends of the shafts Gr have affixed to' them bevel gear-wheels g, which engage with other bevel gear-wheels g affixed to horizontal shafts 9 Both the shafts g are intended to be driven in unison. Advantageously they may be driven by a single electromagnetic engine or motor. If desired, they can of course be driven separately.

By means of the screws E S and their con-' comitant parts, already described, provision is afforded for adjusting the long upright rolls into position for operating upon the sides of a girder-blank while it is under treatment in pass 3 of the rolls B B as shown in Figs. 2 and 3. Provision is also afforded for adjusting the left-hand long upright rolls E E into a position to cooperate with pass 2 of the rolls B B Incident-ally'there will at this time be an adjustment-of the long upright rolls E E, but not for any purpose.v It maybe here remarked that when these long upright rolls are cooperating with pass 2 the short upright.

rolls F F will also be cooperating with pass 2.

For rotating the long upright rolls'E E E E theirupper journals have aflixed to them bevel gear-wheels e ,-which engage with other bevel gear-wheels e mounted upon horizontal shafts c. There are two of these-horizontal shafts, one for the front long upright rolls and the other for the rear long upright rolls. The bevel gear-wheels e have hubs e which are journaled in brackets e rising from the blocks 8 of the upper bearings for the long upright rolls.

These nuts are secured in recesses 5 These bevel gear slide lengthwise upon the shaft e when the long upright rolls are adjusted toward and I from each other, they are connected. with said shafts by splines or equivalent devices, so as to be incapable of independent rotary movement. The two shafts e may be driven in unison or separately, and preferablya reversantifriction metal f cap f and bolts and nuts P, which correspond in construction, relative arrangement, and function to the parts designated in connection with the upper and lower bearings for the long rolls, except that the bolts and nuts f have to be slackened or tightened in connection with the turning of the screws f in order to eifect, adjustments of the bearing-boxesf These short upright rolls F F are not shown as being capable of any other adjustment than that afforded by the bolts and nuts f in conjunction with the screws f nor are they shown as being positively driven.

It will thus be seen that according to my invention means are provided in a rolling- With these boxes are com mill for rolling and forming at least partially one or more flanges and the web of the blank, leaving one or more thickened portions on the web,which, it will be observed, are not adseparatelyfrom the flange portions and with decreased resistance. The rolling means provided leave the thickened portion of the web of the blank separated by channels'from the flange portions, and according to my invention the rolling-mill is constructed to roll down the said thickened portions of the web and expand or widen out the web, whereby the lateral flowing of the metal of the web is facilitated independently of the metal in the flanges.

It will be seen that the main rolls in rolling-mill are provided with reduced portions for forming thicken-ed portions on each side of the web of a blank and parallel to the flanges thereof. Collars are provided at each side of the central reduced portions of the rolls, and there are grooves outside of'said whereby the longitudinal strains on the flanges in rolling and forming the blank are reduced. The main rolls are constructed to produce a blank for an I-beam or girder, having'thickened portions on the web, disposed longitudinally thereof and parallel to the flanges of the blank, the said rolls also being provided with means for rolling down the &

said thickened web portion of the blank, or, in other words, the rolls are constructed to first produce a blank for an I-beam or girder having thickened portions on the web of the same disposed longitudinally thereof and parallel to the flanges of the blank, and the rolls are so constructed that the blank thus produced may be rolled down to the finished form.

Obviously some features of my invention may be used without others, and my invention may be embodied in widely-varying forms, and I therefore do not limit myself to the construction shown and described.
