To all whom, IIT? may concern.-

Be it known that I, EDWIN E. SLioK, of Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Method of Rolling Flanged Shapes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figures 1 and 2 show the successive passes arranged in accordance with my invention in two three-high mills, and Fi 3 is a view similar to Fi 2 showing a diflerent arrangement of the flnishin passes.

My invention re ates to the rolling of shapes having wide flanges, and is designed to produce such shapes without the use of universal mills.- v y In the drawing, Figure 1 shows a three-high mill having rolls 2, 3, and 4, and containing five passes. I start with a bloom or billet, which in passing through thefirst ass a isprovided with the longer dia onal y opposite'flanges 5 and 6 and with t e shorter rudimentary flanges 7'and 8. The metal then returns through the pass I), in which the flanges 7 and 8 are elongated and the flanges'5 and 6'. are contained in the dead groove, andhence not elongated. It will be noted that the flanges 5 and 6 which are in the live groove in the first pass are in the dead grooves in the second'pass. It will also be seen that the live grooves are formed by substantially flat faces which taper'or' converge toward each" end of the pass. The live grooves therefore ways closed; and by maki'n the faces of the live grooves substantially fla and outwardly converging, I obtain the very substantial elongating of two of the flanges. In the third pass 0 the flanges 5 and 6 are within the live grooves and are therefore elongated while the flanges 7 and 8 are within the dead grooves and are not elongated. In the next pass d the flanges 7 and 8 are elongated in the fifth pass 6 the flanges 5 and 6 are elongated in the open live grooves, while the flanges 7 'and 8 .are within the dead grooves. In the pass 7 of the second set of rolls 9, 10 and 11,

thinner in the live grooves, while the flanges 5 and 6 are within the dead grooves. In this the sixth pass, the flanged shape, which may be passed through either in this case is a wide flanged I-beam, is brought substantially to its final dimensions, but the flanges are inclined outwardly in opposite directions. The next pass or passes are merely bending passes which bend the flanges into parallel lanes to form the I beam. In the sevent ass 9 the web 12 is substantially horizonta and the upper flanges 6 and 7 are bent into roper position, while the lower flanges 5 an 8 remain bent outwardly. In the final eighth pass h, the web '12 is horizontal, and the lower flanges 5 and 8 are bent into planes at right angles to the web, thereby finishing the beam. In

this second set 0? rolls I have shown supplemental passes g and h, so that the metal 9 or g in the seventh pass and either it or h in the eighth pass.-

It will be noted that in the bending pass or passes the web is supported by the rolls at.

the same time that the flanges are being bent to form. This is an important feature of my invention, since it prevents buckling of the web and insures a good product. It will also be noted that in all of the reducing passes the web is at an-angle to the axis of the rolls, this angle being reversed in successive passes.

In the modified passes of Fig. 3 the sixth pass f X is the same as the pass f of Fig. 2, but in the, first bending pass 9 the web 12 is not horizontal, but is inclined, and none of the flanges are bent into final position in this pass. .All of the flanges are bent toward their final position, and then in the final pass h the web 12 is horizontal and the flanges 5, 6, 7 and 8 are bent to final position. In this'case, as in the first form, the web is supported by the rolls at the same time that the flanges are bein bent into their final position. There is a so no turning of the blank to a position at right angles to' the previous It will be noted that this is the case pass. with all the passes.

The advantages of my invention result from the obtaining of shapes having wide flanges by means of ordinary mills other than universal mills having horizontal and vertical rolls. By arranging the diagonally opposite flanges where such are present, alternately in the dead and live grooves, and by shaping the live grooves in the manner above described, I can obtain much wider and thinner flanges than have heretofore been gotten by the use of ordinary mills; The bending of l the flanged shape in passes which support the IIO 7 ing the blank to an an le at 90 to the previous pass. Instead l passing any flange alternately through a live groove and then through a dead groove at each successive pass, the flan e may be passed through two .live grooves efore entering a dead groove or two dead groovesbefore enteringa live groove. This might be donewhere the mill would not perimt a heavy draft, ,or for other reasons, and I intend tocover such variation in myclaims. v

.Variations may be made in the mill or mills employed, in the contour of the flanged shape being rolled, in the number and width of the flanges, &c.,'without departing from my invention. Y

I claim:

1. The method of rolling wide flanged shapes, consisting in passingmetal through successive separate passes, in which the web is at successively opposite angles to the axes of the rolls, passing the flange portions alternately through an open hve groove, and drawing out the flangebetween tapering sub-' stantially flat opposing faces, and then through a dead groove, and then bending the v scribed. v 2. The method of. rolling, shapesihaving1 eta flanges to final position; substantially as dewide flanges, consisting in feeding the.

through a series of separate passes in which the web is inclined. alternately at opposite angles to the. axes of the rolls, rolling the flanges alternately within open live grooves and deadgrooves, drawing out the flange in the open live groove to any width to which.

,the metalwill flow, and then passing such flange through a dead groove; substantially as described.

The methodofrolling flanged shapes, consistingin passing metal through-success sive passes, in which the web is at an angle to the axes of the rolls, passing the flange portions alternately through an openlive groove, and drawing out the flange therein between tapering opposing faces, and ,then through a dead groove, and then bending the flanges to final position and finishing the shape; substantially as described. 7

4. The' method of rolling flangedshapes of general I-beam form, consisting in passing metal through successive passes in which the web is' at an angle to the axes of the rolls,

passing the flange portions alternately through diagonally opposite'open live grooves and drawing out the flanges therein between tapering opposing faces, and then passingthem through diagonally opposite .dead grooves, and then bending't e. flanges to final position while keeping the same surface of the sha e uppermost in all of the passes; substantia ly as described. f

5. The method of rolling flanged shapes, consisting of forming the shape byrolling it with the flanges out of normal angular rela tion to the web, and then feedingthe shape through a rolling pass or passes with at least, one of the flanges in a dead groove, and bending the flanges to normal position therein, while supporting the web throughout the bending operation, and keeping the same surface of the shae uppermost in all the passes; substantial y as described.

6. The method of rolling a shape having at least two flanges, consisting in passing the flange'portions alternately through an open live groove and drawing out the flangebetween tapering opposing faces, and then through a dead groove, with'the web at an angle to the roll axes, and then bending the flanges'to final position'with the upper sur face of the shape inthe first pass the u per surface in all .of the-passes; substantial y as described.

' 7. The method of rolling shapes havin 1 wide flanges, consisting in feeding the metal through a series of separate passes in which the 'webjis inclined alternately at opposite angles to the axes of the rolls, rolling the pair within open live grooves and dead.- grooves drawing out the flange. in the open live groove to any width'to which the metal will flow and then passing such flange through a dead groove; substantially as described.

8. The method of rollin I-beams, consisting-in rolling the shape wit its diagonally lop posite flanges bent 'outof normal osition to thewe'b, andthen rolling and ben ing the 1 flanges to normatpesitio while supporting the web'by co'nta'ct withthe rolls-in each pass, and keeping thev same surface ofthe "of diagonally opposite flanges alternately sha e uppermost-in all the passes; substan tial y as described.

9. Themethod of rolling flanged shapes,

consisting in forming a blank'having a web with flanges bent out-of proper position rela: tive thereto, rolling said blank with the web at an angle to the horizontal and then passing the blank through. at least one bending pass in which the web-is parallel with the axes .of the, rolls while the flanges are bein bent,

and su porting the Web throughout t e rolling an bendingoperations; substantially, as described.

In testimony whereof, I have hereunto set" my hand. i v
