EQULLING FLANGE]? METAL BEAMS @Itt BARS.

. 'Apfllication filed March 23, 1904. Serial No. 199.639.

To all whom it may concern Be it known that I, HENRY GREY, a e itizen of the United States, residing at New Yorkcity, in the county of New York and State of New York, have invented new and useful Improvements in. Rolling Flanged Metal Beams or Bars, of which the following is a specification.

My invention relates to a. process of r0lling flanged shapes or sections, such, for instance, as metal I-bcarns and bars having a web between flanges,

In another application filed in the United States Patent Office September 29th, 1902,

and bearing Serial Number 125,316, I claim the process of rolling flanged shapes or sections comprising the provision of a special blank in which the mean thickness of each; flangeportion and the thickness of theweb-l portion are in the proportion in which the said thicknesses exist in the finished productto which the blank is to be reduced, and during'the reduction of the blank reducing the said thicknesses in the said proportion.

in the present application I disclose and claim a process of rolling flanged shapes or sections consisting in. a proportionate reduction'ot" the Web-portion and fiangsportio'ns of the blank in area of cross-section by rolling pressures on the sides of the said blankportions and on the edges of the flange-portions, and in providing a special blank in which the area of cross-section of. the web-portion and the area of cross-section of each flange-portion are in the proportion in which the cross-sectional areas of the said portions are to exist in the finished product to which the said blank is to be reduced, and substantially maintaining the said proportion in the cross-sectional areas of the said portions of the blank during the reduction of the blank.

In the accompanying drawings, Figures 1., 2, 3 and 4c are cross-sectional views of a blank, shape or section illustrating the reduction of the blank by rolling pressures on the web-portion'and flange portions of the blank during successive blank T reducing passes of the blank. Fig. 5 is an elevation diagrammatically and in central section, illustrating a universal mill employed in applying rolling pressures to the sides of the Web-portion and flange-portions of the blank, and also showing supplemental rolls arranged a suitable distance from the uni versal mill and employed in applying rolling pressures on the edges of the flange- Spccificati m of Letters Patent;

BEISSUED portions. Fig. (i is. a vertical section on line 6-6, Fig. 5, looking in the direction indicated by the arrow.

The drawings also diagrammatically illustrate the two horizontal rolls 0 and a? and the two Vertical rolls f and j of a universal mill. The'vertical rolls f have their axes a v-er tical plane passing through the axes of liorizon'tal. rolls 0 and (Z. l he horizontal rolls 0 and (Z are arranged to operate upon oppo site sides respectively of the web-p0rtion a. and upon the inner sides of the flange-pen tions Z) and are relatively readjusted between successive passes of theblank through the mill. The vertical rolls are arranged to operate upon the outer sides of the flanges and are relatively readjusted between successivc passes of the blank through the mill.

The manner of supporting the rolls of a universal mill, zontal rolls of the said mill toward and freon each other, and means for adjusting the vertical rolls of the mill. from and toward each other are too well known in the art to require illustration and description in this ap A pair of horizontal rolls 9', arranged apply rolling pressures upon the edges ol the flanges, are illustrated in Figs. 5 6 and, as shown in Fig. 5, are located at one side of and a suit-able distance from and parallelly with the horizontal rolls ()f'iliiii? universal mill. In Fig. 5 ablanllt is shown in posit-ion not only being reduced by auniversal mill but being also operated aptn by rolling pressures upon the edges oft-he flanges by the rolls 7 which are relatively adjusted as required preparatory to their operation.,-

The means of supporting the rolls-grind means for adjusting; the said rolls taincreaseor decrease the space between theta, are too well known in the art to require illus tration and description in this application.

The dimensions of the diiterent portions of the blank are indicated in the first tour figures of the drawings, and upon reference observed that duction in cross-sectional area isgi'ven to both the wehportion and the range-per honsyand 1n the case illustrated an l-lieain IS shown being ma de. By proportionate means for adjusting the hori;

fill" duction of the web-portion and flange-portions. in area of cross-section I mean the same percentage of reduction in area of cross-section; that is,if the web is reduced a given per cent. in area in one pass, the flanges are reduced the same or substantially thesame per cent. of their area in this same' pass. v a

' I employ, preferably a special blank hav 1 ing the cross-sectional area of its web-pow tion and the cross-sectional area of each fiange-portionin the proportion which thei cross-sectional area of the'said flange-portion and the cross-sectional area of the webportion bear to each other in the finished product to which the blank is to be reduced and rolling the said flange-portion and the web-portion and thereby reducing the said portions in area of cross-section in the proportion in which the cross-sectional area of the said portions bear to eachother in the blank and in the finished product. -.2nfother'4 I words, I employ a blank having team-0r cross-section in its web-portionand an areaof cross-section in each flange-portion in the proportion which the'cross-s'ectional areas of the said portions existin the finished product, and proportionately reduce the said portions of the blank in area; ofcrosssection during each and every passage of the- I blank. The successive passes are formed by insure the requisite blank.

Several illustrative passes are shown in the draw- What I claim is i I LThe process of rolling flanged shapes which consists in subjecting a blank having web and flange portions, and the izveb portion of which is substantially of the same width as that of the finished bat to successive rolling operations on the sides of said web portion and on the outer face of the flange portions simultaneously, each of which operations successively reduces the cross-sectional area of the shape in its web and flanges in substantially the same proportion from the blank to the :finished product.

2. The process of rolling flanged shapes which consists in subjecting a blank having web and flanges, the web of which is substantially otthe same widthas that of the finisheld, bar, hi0 successive rolling operatlons, each of said rolling operations simultaneously reducing the thickness of the web and the mean thickness and width of each flange, and "at the same time reducing the cross-sectional area to thesame proportionate extent. l

3. The process of rolling flanged shapes which consists in subjecting a blank having a web and flanges, the areas of the web'and the areas of the flanges having approximately the same relative proportions as they have in the finished product, to successive rolling operations on the sides of the web and the flanges, and simultaneously therewith subjecting eachof the flanges to rollj-ngpressures applied to the edges thereofppach of said rolling operations reducing thethickness'of the web and also reducing the mean thickness and width of each flange while simultaneously reducing the cross-sectional area of the web and the fianges to thev same proportionate extent. i I 4. The processof rolling. flanged shapes which consists in taking ablank, the thick-g ness of the web of which and the n1e'an thickness of each flange of which substan- I tially have the same relative proportions as they are to have in the finished product and theareas of the web and the areas 01% the flanges having approximately the same relative roportions asjthey have in the finished gtoduct, and subjecting said blank to a series of rollingoperations, whereby each'of said operations successively reduces thecross-sectionalarea of the shape to the same predetermined extent. 4
