. l 'I Application'med November 28, 1902. Serial No. 133,098.

To all whom'it 'may concern: V n i h, Be it known that I, 'HENRY GRE?, a citizen of the UnitedStates ofgAnierica,a,es1ding at New York, in the county of NewQork and havel invented certain new and useful Improvements', in",Rollmg-zA State of New York,

Mills; and I hereb declare'the following to be a full, clear,andl exact description, of the invention, such as'will enable othersskilled in theart to which' it pertains to make and use the same. A

,This invention relates to improvement in mills or apparatus for rolling metallic beams, girders and structural work" generally. n j

This invention pertains more especially to a mill which is adapted for use in rollingl flanged beams or bars and comprises, first,

ranged one above the other and in the same vertical plane and next above and next below the path of the blank to be operated upon and in position to operate u pon the upper.

respectively, of the web" Yof the blank or work and upon the inner side and lower side,

sides ofthe flanges or heads of the blank or work', with one of the said rolls, Aand prefer ably the top roll, adjustable vertically toward and from the other roll; second, two

y vertical or upright side rolls arranged next to and at opposite sides, respectively, of the path of the blank and in positi 4n to operate upon the entire outer sides ol.I the heads or flanges of the blank or work and Carried -by slides or supports which are adjustable toward or from each other so as to render the said side rolls adjustable apart; third, another pair of supplementary horizontal rolls arranged a suitable distance laterally of and from and parallel with the aforesaid web-reducing rolls and in position to opcrate upon the edges of the. flanges or heads of the blank or Work in the passage of the latter to or from the web-reducing rolls and adjacent side rolls ;l and, fourth, a covered passage-way for conducting and guiding the blank or work in its passa e between the web-reducing rolls and the a oresaid supplementary rolls.

One object oic the present invention is to provide a desirable top bearing as well as a bottom bearing for each vertical side roll employed to operate upon the outer side ot a flangev or head of the blank or work, and

,successfully prevent upward displacement of provlsion,

swhich has rside walls,

strai-n upon the screw. which is employed in retaining .the said top bearing in place and engages""a. correspondingly screw-threaded hole formed in the axle embraced by the said roll. wouldv here remark'that I am aware 'that with necks on, the ends of the said vertical--'rolls the frames or supports holding such necks'would offer resistance to the rising of the said rolls vertically, but in prac# tice when making wide-flanged'bars, ubeams or sections, the construction of these rolls withl necks thereon would have the result of so lncr'easing the diameter-.of the body of rolls, or decreasing the diameter of the neck of the said rolls, that the. millv would be incapable of resisting the forces employed. a pa1r of horizontal web-reducing rolls ar- Another object of this invention is the between the web-'reducingrolls and the rolls employed tooperate-'0nthe V,edges of the flanges or heads ofthe blank vor wor-k, of a work-conducting passage-way top'and bottom walls, all extending approximately from a point in close proximity to the last-mentloned rolls to a point in close proximity to the web-reducing rolls, so that lthe blank or work, in its passage between the pair of web-reducing rolls and the pair of rolls arranged to operate on the edges of the heads or flanges of the blank or work, shall be continuously guided not only in a lateral but also a vertical direction. I would remark, first, that the bottom wall or bottom of the said passage-way prevents downward displacement of the blank or work and is enough narrower than the space between the side walls of the said passage-way to alford a bottom-bearing only for the web of the blank or work; second, that the top or covereforming wall of the said passage-way is preferably made in vertically adjustable sections which form guides arranged to prevent upward displacement of the blank or work and immovable except during a readjustment ofthe same, and means whereby the said sections are simultaneously raised or lowered simultaneously withl the elevation or lowering of the top web-reducing roll is provided, and third, the opposite side walls of the said passage-way are ar-- ranged at opposite sides, respectively, .of the path of the blank or work and form guides arranged to prevent displacement of the 'l-the said roll during the reduction of the l n -blankby `the roll fand to avoid torsional work, and are pivoted vertically near thevertioal side rolls to the dierent slides respectively which carry the said side rolls,

and move toward or from each other simultaneously and equally with the adjustment apart of the said side. rolls according as the aforesaid slides are actuated toward or from each other.

Another object of this invention consists in connection with the pivoting of the said side guides near the -verticalside rolls to the slides which carry the said rolls, in extending the said guides between and beyond the outer side of the rolls employed to operate upon the edges of the heads or flanges of the blank or work, and providing means, preferably at the outer sideI of the said lastmentioned rolls, whereby is facilitated the swinging of the said guides toward or from each other simultaneously with but a greater distance than the movement of the vertical side rolls toward or from each other so as to enable blooms or blanks, which are not straight, to readily pass between and caught by the rolls employed to operate on lthe edges of the flanges or heads of the blank and to participate in effecting a gradual straightening o the blank during the reduction of. the blank.

Another object of this invention' is to so connect the inner end-portion or member of each slide which carries a side roll with the outer end-portion or member of the said slide, which outer slide-member is provided with thrust-bearing-forming rollers against which the said side roll bears laterally and outwardly in rolling, that the said side roll is yieldingly maintained, by'an elastic pressure, against the said rollers and does not spring from the said rollers when the blank or work passes from between the two side rolls and consequently is not thrown violently against the said rollers when the said rolls engage the work.

With these objects in view, and to the end of realizing other advantages hereinafter appearing, my invention consists in certain features of construction, and combinations of parts, hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a top plan of a rolling mill embodying my invention, and portions are broken away and in section in tlns ligure to more clearly show the construction. Fig. 2 is a side elevation of the mill, largely in central section, and portions are broken -away and in section in this figure to more clearly show the construction. Fig. 3 is a top plan of the mill, largely in section taken between the rolls of the pair of web-reducing rolls B and B2 and between the pairs of flange-ed e-rolling rolls A and A2. Fig. 4 is a side e evation in section and in detail, illustrative of the connection between the members al and e of a slide H.

l tion of the operative connection between the shaft M and the top guides 47 and 48. Figs. 2 and 3 are drawn on t-he same scale and on a somewhat larger scale than Fig. 1. Figs. 4 and 7 are drawn on the same scale and on a scale larger than Figs. 2 and 3. Figs. 5 and 6 are drawn on 'the same scale and on a `scale larger than Figs. 4 and 7.

The mill illustrated in the said drawings comprises an upper horizontal roll B, a lower horizontal roll B2 and two vertical side rolls D and D arranged at opposite ends, respectively, of the said horizontal rolls, and centrally between the axes of the said horizontal rolls. The top and bottom rolls B and B2 form a pair of web-reducing rolls arranged one above the other and in the same vertical plane and next above and next below the path of the blank to be operated upon and in position to operate upon the upper side and lower side respectively of the web of the blank or work and upon the inner sides of the flanges or heads of the blank or work. The two vertical or uprightl side rolls D are arranged next to and at opposite sides, respectively of the path of the Work and in position to operate upon the entire outer sides of the heads or anges of the blank or work, and carried by slides which' are adjustable toward or from each other, as will hereinafter appear, so as to render the said side rolls adjustable apart. The blank or work C' is shown in position in Fig. 4. The top roll B is adjustable vertically relative to the bottom roll B2 which is supported in any ap roved manner from two housings G and (if) y at opposite sides, respectively, of and a suitable distance from the path of the blank or work. The rolls B and B2 are practically of the same diameter and rotated in opposite directions respectively, but means for rotating the said rolls are too well known to require description or illustration in this application. The side rolls D may be driven by the contact of the blank or work therewith or in any other approvedmanner.

The blank or work is given as many passes through the mill as are required to complete the rolling or shaping ofthe Work, and the blank or work is of course suitably heated preparatory to its introduction into the mill, and the work is fed with its web arranged horizontally.

It is obvious," that for work of the character indicated the adjustable top roll B and the adjustable side rolls D are, at the commencement of the operation of the mill, set as required for the first pass of the bloom or heated blank. rolls B and D, relative t ,the path of the blank or work, is effected simultaneously,

and the side rollsD, in adjusting them apart simultaneously with the adjustment of the top roll B, are moved more rapidly than the top roll in order to avoid long crop ends and torn or cracked flange-edges on the finished product..

Each housing G, near its lower end adjacent to the adjacent trunnion of the bottom web-reducing roll B2, is provided with brackets Gr which form a slideway for and support the outer' end-portion or member d of a slide H whose inner end-portion or member e carries one-of the side rolls I). The two slides H are movable with and in the direction in which the side-rolls D are adjustable. Both slides H are movable, therefore, toward or from each other. Each .slide H is operatively connected, at its central portion, with a screw H2 arranged parallel with the travel ofthe slide, which screw engages a correspondingly threaded nut I (see Fig. 3) rigidly secured within and to the outer end-portion or member d 0f the slide. The said member d is connected .with but has an adjustment toward and from and independently of the roll-bearing inner endportion or member e of the said slide, which member e is suitably supported from the .housing which supports the aforesaid slidemember d. Preferably thel legs-of each housing G are connected together at the bottom by a web g as shown in F igs.2 and 4. The webs g support the bottom-web-reducing roll B2 and the inner end-portions or roll-bearing members e of the slides H.

The outer member d of each slide H carries the thrust-bearing for the side roll D carried by the inner member e of the said slide, and the said thrust-bearing (see Fig. 3) comprises two large vertical rollers J and J arranged a suitable distance apartat the outer side of and engaging the said side roll. Two rods It are attached to the said inner or roll-bearing slide-member e and extend, parallel with the travel of the slide, freely through the outer or roller-bearing slide-member d, as shown more clearly in Fig. 4. The space had between the two slide-members d and e accommodates the adjustment of the outer slide-member al upon the said rods It toward the inner slide-member e. The adjustability of the outer slidemember d accommodates the taking up of any wear between the said side-roll D and the engaging rollers J and the-maintenance of the said rollers in contact with the said roll, andthe said slide-member d is yieldingly retained in the adjustment required to hold its rollers J in contact with the said roll D by springs which are mounted and The adjustment of the conned upon the rods l1, between the outer- 'is recessed, as at e, to receive the said nut h3 with sufficient closeness to prevent .den taclnnent of the said rod from the said slidemember 'during an endwise. and outward pull upon the saidrod. It will be observed therefore, that 'the inner and roll-bearing slide-member e of each slide is hitched to or l connected with the outer and roller-bearing slide-member d of the said slide in such a manner that the said inner slide-member is shifted simultaneously with the said outer slide-member during a readjustment apart of the two slides H.

By the construction hereinbefore described it is obviou's'that the rollers .l of the slide-member d of each slide H are' yieldingly and constantly held lagainst the roll D of the inner member e of the said slide so that the'said roll does not -spring`from the said rollers when the blank or work passes 'from between the two rolls D and consequently is not thrown violently against the said rollers when the said rolls again engage the work.

Each slide-operating screw H2 extends from the connected slide H outwardly through a yoke-forming bar G2 which connects together and is secured to the two legs of the housing whichsupports the said slide.

- Two collars H3 and H3, which are fixed or.

formed upon the said screw at opposite sides respectively of the said yoke, prevent endwise movementof the screw during the ro'- tation of the screw. It is obvious that each slide H, and the side roll D supported thereby, are adjusted toward or from the pair of horizontal rolls B and B2 according as the connected screw Hz'is turned in the one direction or the other.

The means employed for holding each side-roll D down upon its support which, as already indicated, is formed by the inner end-portion or member e of the slide H which carries the said roll, is shown very clearly in Figs. and 6. The said slidemember e is provided, centrally of thesaid roll D, with an upwardly projecting and vertically arranged axle l0, and the said roll is bored vertically and centrally to accommodate the location of the said axle and the means employed in forming a top bearing for the roll. The said roll D is provided, in its lower end, with -an annular recess 12 which extends around thelower endof the axle so as to form, within the lower por- `cess 15 whichisarrangedin the main above and extends around the upper end of the axle 10 so as to form, within the upper portion of the roll, adownwardly facing annular shoulder 16. Thevsaid axle 10`is provided, in its upper end and centrally, with a circular recess 17. A disk or cap 18, which forms the top-bearing of the said roll D, is arranged within the upper recess 15 and overlaps anti-friction devices which are in the form of conical rollers 20 interposed between the shoulder 16 and the said cap. The rollers` 20 are arranged radially and taper inwardly. The cap 18 is provided'centrally with a depending boss 22 which extends into and snugly fits the recess 17, and a screw 23 extends centrally and vertically through the said boss. into engagement with a correspondingly screw-threaded hole 24 formed in the axle, which screw is provided, at its upper end, with a head or member 25 arranged to hold the said cap downwardly. Means which prevents circumferential displacement of the cap 18 is rovided and comprises, preferably, any suitable number of keys 26 which extend from within the boss 22 to within the boss-surrounding wall of the recess 17.

By the construction hereinbefore described it will be observed that the provision of necks on the side-rolls D is avoided; that a rising of the side-rolls D upon the axles 10 toward the necks of the top horizontal roll B is prevented, and consequently a top roll B having diametrically large necks or trunnions is accommodated; that the said side rolls are adequately supported at the bottom; that vertical displacement of the said side-rolls is efl'ectually prevented and conse-v quently the said side rolls will at all times be in position to completely cover the flanges or heads of the blank or work upon which the l said side rolls operate during the operation of the mill. Also, by the construction hereinbefore described the frictionv between the caps or top-bearings for the side rolls D is reduced to a minimum and circumferential displacement of the said top bearings is effectually prevented, and torsional action upon the screws 23 is avoided.

Two vertical screws L (see Fig. 1) are arranged above the different necks or trunnions respectively of the top horizontal roll B. Each screw L, as shown in Fig. 2, engages a correspondingly screw-threaded nut lL3 fixed or formed in the top of the adjacent housing G. Between the lower end of each screw L and the adjacent'trunnion or neck of the top roll B is interposed a saddle Z (see Fig. 2), and-the said neck or trunnion has bearing in a half-box Z which rests upon a vertically movable frame or structure Z2 engaged and held in the desired adjustment by the piston Z3 of a hydraulic cylinder Z* and obviously instrumental in supporting the said roll at the desired elevatlon controlled by the screwsL. v

The 'mechanism employed for rotating the screwszf/L and H2 is shown to be as follows Upon the upper end or portion of each screw L (see Fig. 1) is operatively mounted a worm-wheel L which meshes with a worm M formed -upon a suitably supported horizontally-arranged shaft M which is arranged at the top of and above the housings G. The upper ends of screws L'are angular in crosssection and extend through corresponding holes in the central portions of the engaging wheels L without interrupting operative connection between the said wheels and screws. Theshaft M is suitably driven in the one direction or the other according as the screws L, and consequently the top roll B', are to be elevated or lowered. The shaft M is operatively provided, at one end, with a driving-wheel M2 to which power is applied in any approved manner. Upon the outer end of eachscrew H2 (see Fig. 3) is operativel'y mounted a worm-wheel H5 which meshes with a worm 71,5 formed upon a suitably supported upright shaft h4. Each shaft it* is operatively provided, at its upper end, (see Figs. 1 and 2) with a bevel-gearh6 which meshes with a bevel-gear NG operatively mounted upon a shaft N which is suitably driven in the one or the other direction according as the slides H, and consequently the side rolls D, are to beshiftedtoward or from each other. The shaft N is operatively provided, at one end, with a driving-wheel N to which poweris applied in any approved manner.

It is obvious that, as already indicated, the top web-reducing roll B and with it the ange-reducing side rolls D are set, preparatory to the first pass of a heated blank that requires reducing, the distance apart required for the first pass, which distance forms the largest work-receiving passage between the said rolls during the reducing operation upon the blank, and said passage is rendered smaller preparatory to each successive pass of the work, and the rolls after therwork has had its finishing pass are readjusted to enlarge the .work-receiving passage between them as required for another blank.

At one side and a suitable distance laterally of the horizontal web-reducing rolls B and B2 (see Figs. 1, 2 and 3) are arranged two horizontal rolls A and A2 which are other at their adjacent ends.

eaaeee parallel with the rolls B and AB2 and arranged one above the other and. respectively next above and next below the path of the blank or Work to be operated upon and shaped and placed to operate u .on the edges of the heads or flanges of the b ank or work. The rolls A and A2 are supportedin a manner substantially the salne as the manner of supporting the rolls B and B2. The upper roll A is adjustable vertically from the lower roll A2, adjusting the top roll A saine as the means for adjusting the webreducing roll B and does not constitute any portion of the claimed subject-matter of this application. The rolls A and A2 are operated in any approved manner.

The passage-way for the blank or work between the web-reducing rolls B and B2 and the lange-edge-rolling rolls A and A2 is practically closed at the top as well as at the sides and bottom from-end to end of the said passage-way. The bottom wall or bottom of the said passage-way is preferably a bar or plate 34 which is supported in any approved manner and extendsfrom a point in close proximity to the bottom web-reducing roll B2 to a point in close proximity to the bottom roll A2 as shown in Fig. 2. The top wall or cover of the said passage-way is formed by two plates 47 and 48 arranged next adjacent to the top roll A and top roll B respectively. The plates 47 and 48 form top guides which prevent upward displaceand the means for is substantially the nient of the blank or work. The guide 48 extends from a point in close proximity to the roll B a suitable distance toward the roll A'. The guide 47 extends from a p'oint in close proximity to the roll A a suitable distance toward the roll B. The guides 47 and 48 extend into close proximity to each The guides 47 and 48 are simultaneously raised or lowered according as the top web-reducing roll B is elevated or lowered during a readjustment of vthe said roll, as will hereinafter more clearly appear. As shown in Figs. 1 and 2, the guide 47 is carried, at its end which is adjacentto the roll A, by a slide 51 mounted ona box 49 which is pivoted horizontally and transversely of the path of the blank or work by rotatably mounting it upon a shaft or rod 50 which is correspondingly arranged transversely of the said path and at the top of the said guide and supported in any approved manner, as, for instance, by the housings 30' in which the rolls A and A2 are i mounted. The slide 5l extends longitudinally of the guide 48 a suitable distance beyond opposite sides of the box 49 so that the guide 48 is capable of sliding longitudinally.

Adjacent ends of the guides 47 and 48 (see Figs. 2 and 7) have interlocking ears 46 easily embracing a shaft or pin 52 which is arranged horizontally and' transversely of toward and endwise independently the path ort the blank or work. A vertically shittable slideforming bar 45' is arranged parallel with and longitudinally of the pin 52 above the ears 46 and is rovided, at its under side, with depending boxes 44 which afford bearing to the said pin. The bar or slide 45 engages correspondingly vertically arranged slideways 43 formed in the housings G. Two vertically arranged screwthreaded spindles 57 are arranged a suitable distance apart between the housings Gr and engage with correspondin ly vertically arranged and corresponding y threaded nuts 58 which are secured to the said housings; The screws 57 extend loosely through the slide 45 and have collars 42 at the top and bottom of the said slide so that the screws are turnably attached to the said slide. Each spindle 57 extends upwardly through and a suitable distance above the engaging nut 58, and on each spindle, above the engaging nut, is operatively mounted a worm-wheel 60 which rests upon a bracket 40 secured to the adjacent housing G. The worm-wheels 60 mesh with worms 61 which are formed upon a shaft 62 arranged horizontally and extending between and supported from the housings G. The operative connection between each spindle 57 and the engaging wormwheel 6() is such that the spindle can move of the worm-wheel, and in the mill illustrated the upper portions of the said spindles are angular and extend easily through correspondingly angular axial bores in the said wheels. A sprocket-wheel 63 is operatively mounted upon the shaft 62 between the two worms 6l and is operatively connected by a chain 64 with a sprocket-wheel 65 which is operatively mounted upon the worm-shaft M. The arrangement of the parts is such that both guides 47 and 48, by the operative connection between them and the worm-shaft M, are simultaneously lowered or elevated according as the top web-reducing roll B is lowered or elevated by power transmitted to the said roll from the shaft M. A counterbalance for the guide 48 is provided and consists of a weight or poise 55 arranged above the central portion of the guide 47 and mounted on a lever 53 which is fulcrumed, as at 54, to the slide 45 and, between the said slide and the top roll B', is operatively connected, by a link 56, to the guide 48. The under sides of adjacent ends of the guides 47 and 48, below their interlocking ears 46, preferably slope or curve upwardly toward the extremities of the said ends, and the guide 47 turns or curves upwardly toward the roll A between the said roll and the pivot 50.

The side walls i of the passage-way extending between the two pairs of rolls B B2 and A A2 form guides which are instrumental in preventing displacement of the blank or work laterally of the said passageway in opposite directions respectively when the blank or work is being passed from one to the other of the said airs of rolls. The uides 9' are pivoted vertically, as at 1", (see 4`inf. 3) to the roll-bearing member c of the different slides Il respectively so that the said -guides are adjusted apart simultaneously with the adjustment apart of the siderolls D and while they are adjusted apart are capable of being swung horizontally on their pivotal bearings toward or from each other forthe purpose more especiallybf enabling the said guides to recede from or approach each other morel rapidly than the said rolls D recede from or approach each other duringa readjustment of the slides H. The guides I1' extend from their pivotal bearings r (see Figs. 2 and 3) to and between the lange-edge-rolling rolls A and A2 and beyond the outer sides of the said rolls where the said guides are operatively connected with the mechanism employed to actuate the said guides toward or from each other simultaneously with and in addition to the actuation of the said guides toward or from each other by the operation of the slides H, which mechanism (see Figs. l and 2) comprises preferably a horizontally arranged shaft t which extends transversely of and below the Works path through the lower portions of the guides 7'. A righthanded screw t is formed upon the shaft t at the outer side of one of the said guides r, and a left-handed screw t2 is formed upon the shaft at the outer side of the other guide r. Screws t and t3 are operatively engaged by two nuts t2' and tt, respectively. Said nuts t2 and t* have bearing in and are arranged to slide endwise of lugs g* formed upon the housings Gr, and each. guide 7' is operatively connected with one of the said nuts, and in the mill illustrated the lower portion of each guide 7 slidably embraces the shaft t and engages a recess t5 formed in the inner end of the connected nut. Shaft t is operatively provided, at one end, with a bevel gear t which meshes with a bevelgear t7 operatively mounted upon a suitably supported shaft t8 which is arranged horizontally and at right angles to the shaft t. Shaft t2 extends from adjacent the shaft t toward and into suitable vproximity to a shaft-T which is arranged parallel with the shaft t. The shaft adjacent the shaft T is operatively provided with a bevel-gear t9 which meshes with a bevel-gear T9 fixed to the shaft T.

As already indicated, the side-guides rare arranged at that side of the airs of rolls B and B2 which faces the we -reducing-rolls A and A2, but at the opposite side of: the said pairs of rolls B and B2 are arranged two side guides and work-straightening bars R which are arranged at opposite sides respectively of the path of the blank or work. 'lhe bars R are plvoted vertically, as at. R', to the. roll-bearing member c of the dili'erent slides .il respectively so that the said bars areI adjusted apart simultaneously with the adjustment. apart of the side-rolls l) and while they are adjusted apart are capable of being swung horizontally on their pivotal bearings toward or from each other for the purpose more especially of enabling the said bars to recede from or approach each other more rapidly than the said rolls I) recede froln or ap roach each other during a readjustment o the slides H. The bars R extend from their pivotal bearings r (see Figs. l, 2 and 8) a suitable distance longitudinally of the path of the blank or work and are operatively connected,' near their outer or free ends, with the mechanism employed to actnate the said bars toward or from each other simultaneously with and in addition to the actuation of the said bars toward or from each other by the operation of the slides H, which mechanism comprises preferably the shaft T which, as already indicated, is arranged horizontally and extends transversely of and below the path of the blank or'work through the lower portions of the bars R. A right-handed screw T is formed upon the shaft T at the outer side of one of the bars R, and a left-handed screw T3 is formed upon the said shaft at the outer side of the other bar R. Screws Tv and T3 are operatively engaged by two nuts T2 and T4, respectively. The said nuts have bearing in and are arranged to slide endwise of lugs G4 formed upon the housings G, and each bar R is operatively connected, with one of the aforesaid nuts, and in the mill illustrated the lower portion of each bar R'slidably'embraces the shaft and engages a recess T formed in the inner end of the connected nut. The shaft T is operatively provided with a worm-wheel T which meshes with a worm T'I formed upon a diagonally-arranged shaft T8 which extends into close proximity to the shaft N (see Figs. l and 2) and is operatively provided with a bevel-gear T20 which meshes with a bevelgear N10 operatively mounted upon the said shaft- N.

By the construction hereinbefore described it will be observed that if the screws H2, and the shafts t and T are rotated at the same speed, a pitch of the threads of the 'shaft t, greater than the pitch of thethreads of the screws H2 will result in the adjustmentapart of the guides r by the operation of the shaft t more rapidly than the adjustment apart of the said guides by the adjustment apart of the slides H, and that a pitch of the threads of the shaft T greater than the pitch of the threads of the shaft t will result in the adjustment apart of the workstraightening bars R by the operation of the Maese shaft 'l not only nore rapidly than the adjustment apart of tbe. said-bars by the adjustment apart of the slides H ut more rapidly than the adjustment apart of the said Guides -2 by the operation of the shaft t.

Albottoin-guide or support u arranged next below the ath of the` blank or Work between the wor t-straightening bars R is of course provided.

I would here remark that the pivotal connection of the side guides directly with the slides in suitable proximity to the vertical side rolls whereby the said guides are adjusted simultaneously with the adjustment of the said slides, and the means for swinging the said guides toward or from each other during their adjustment by the shifting of the slides, constitutes a meritorious and notunimportant combination when the necessity of having the mill readily capable of receiving and operating upon crooked blanks is considered. A variety of curves are found in blanks bron ht to the mill, and when the front end of a lanlg-that is, the end of the blank which iirst enters the mill,-is crooked the side guides must be far enough apart' at Vtheir outer ends to enable the blank to reach the rolls'. The pivoting of the side guides to the slides which carry the vertical side rolls accommodates the maintenance of the required close relationship between the inner ends of the. said guides and the said rolls and at the same time accommodates the swinging of the said guides far enough. apart at their outer ends to permit a curved or crooked blank to readily pass between them to the rolls.

The bottom wall or bottom of the passageway for the blank or work between the webredncing rolls B, B2 and the {hinge-edgerolling rolls A', A2, and the top Wall or cover over the said passage-way and formed by the bars or plates 47 and 48, are, as shown in Figs. 2 and 3, arranged respectively next above and next below the path of the web of the blank and between the side' guides r. The said bottom and the said cover are a little less in width than the web-reducing surfaces of the web-reducing rolls B', B2 and perform the functions of lateral or side guides between the paths of the heads or v{ianges of the blank as well as bottom and top guides for the web. Hence the top wall or cover and bottom wall of the said passageway prevent displacement of the blank laterallyof the pat-h of the blank as well as vertically, and the said passage-way is practically closed at the top, bottom and sides from a point in close proximity tothe flangeedge-rolling rolls to a point in close proximity to the web-reducing rolls.

Referring again to the application and operation of the guides r I would remark that my invention embraces broadly the provision, in connection with the horizontal rolls and vertical rolls and the slides carrying the different vertical rolls respectively and adjustable toward and from each other, of two guides arranged at one side of the horizontal rolls but at opposite sides respectively of the path of the blank, which guides are pivoted or fulcrumed vertically at one end to the different slides respectively and independently adjustable at the other end so that the said guides are capable of being swung toward or from each. other while they are adjusted by the shifting of the slides, and means for swinging the said guides toward or from each other at a reater speed than the mechanism which adjusts t-he aforesaid slides so that the space between the outer ends of the guides is enlarged or decreased during the adjustment of the guides by the shifting of the slides and so that, as already hereinbefore indicated, the maintenance of the required close relationship between the inner ends of the said guides and the vertical rolls is accommodated as well as the swinging of the said guides far enough apart at their outer' ends to permit a crooked or curved blank to readily pass between the guides. In other words, by the construction and arrangement of parts described and shown the inner ends of the guides r are kept in approximately the same position relative to the vertical rolls which move inwardly at every adjustment, and the ends of the guides which protrude beyond the flange-edge-rolling rolls are moved faster than the ends carried by the slides. A close relationship is kept between the inner ends of the said guides and the vertical rolls, and at the same time the guides can be swung, at their outer ends where they irst receive the blank, far enough apart to pel'- mit the various and indefinite variety of crooked shaped bars or blanks coming to the mill.
