To all whom it may concern Be it known that I, GEORGE H. BARBOUR, a citizen of the UnitedStates, anda resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have i invented a new and useful Im rovement in Methods of Bending Flange 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 Figure 1 is' a front view of a portion of a three-high mill showing one method of bending flanged sections from a blank. Fig. 2 is a similar view for bending flanged sections from a differently shaped blank. Fig. 3 is a similar View for bending a differently shaped section from the blank shown in Fig. 1. Fig. l is a similar View for bending a section similar to that shown in Fig.3 from a blank similar to that shown in Fig. 2. Fig. 5 is a similar view of an apparatus for bending still a differently shaped section from a blank similar to that shown in Fig. 1. Fig. 6 is a similar view of an apparatus for bending still another former section from a blank Figs. 7 8', 9, 10 and 11 are sectional views of a plurality of blanks and sections formed therefrom by my method.

My invention relates to an improved method for roll-bending flanged sections having a web and a plurality of flanges, and is designed to provide a cheap and efficient method of bending theflanges or a portion thereof with relation to the web.

The precise. nature of my invention will be best understood by reference to the accompanying drawings, which will now be described, it being premised, however, that various changes may bemade in the details of construction of the apparatus and general arrangement of the parts, as well as the various steps of the method, without departing from the spirit andscope of my invention, as defined in the appended claims. In Figs. 1 to 6, A, B,'and C designate the rolls of a three-high mill, between which is formed a plurality of passes for bending the various sections from the blank.

In Fig. 1, I have shown an apparatus for bending a section such as is shown at a which consists of a web and a plurality of flanges at each end of the web, a portion of each of the flanges being at substantially right angles to the web, while the extremities thereof are at substantially right angles to the other portions of the flanges and substantially parallel with the web. In forming this section, I take ablank, as indicated at a, and run it through a pass a in which both sides of the web are engaged by the rolls, while the web extends at an angle of approximately 455 degrees to the axes of the rolls, and in which pass, I bend a portion of two of the flanges at an angle of approximately 90 degrees to the web, and maintain the other two flanges at approximately an angle of 45 degrees to the web. I then run the section through a second pass, as indicated at a and maintain the web at an angle of approximately 45 degrees to the axes of the rolls, and bend a portion of each of these flanges at anangle' of 90 degrees to the web, without changingthe angular relation of the other portions thereof. After the blank has been run through this last mentioned pass, a portion of each of the flanges will extend at substantially right angles to the web, while the outer extremities thereof will extend at an angle of substantially 45 degrees to the other portions of the flanges and the web. I then run the blank through a pass, such as in dicated at a and bend the extremities of one of the flanges at each end of the web at about right angles to the other portion of each flange and parallel with the web. The blank is then run through another pass, as indicated at a to bend the extremities of the other two flanges to form a section hav-' ing a web and a plurality of flanges at each end of the web, the outer extremities of the flanges being substantially parallel with the web and at about right angles to the other portions of the flanges.

In Fig. 2, I have shown another form of apparatus for rollingthe same section from a section or blank such as shown at m and n in Figs. 5 and 6, respectively. In this case, I bend the outer extremities of two of theflanges at an angle of about 45 degrees without disturbing that portion of the flanges adjacent to the web as indicated at 6 The blank is then run through a pass, as indicated at Z2 to shape the blank similar to the blank shown at a in Fig. 1. This I blank is then run through passes Z) and b which are similar to passes a. and a of Fig. 1. I

In Figs. 3 and 4:, I have shown rolls for forming a section similar to those shown in Fig. 1, with the exception that in these sec- 15 or substantially 90 degrees to the web. The

blank is thensuccessively run through passes c andc to bend the outer extremities of theflanges at substantially right angles to the other portions thereof. Itis then run ;Z through passes 0 and 0 to bendthe flanges 451 degreeswith relation to the-web,=so that portion ofeach flangeextends at substantially right anglesto the web, and another portion substantially parallel therewith.

In Fig. 4, I have shown an apparatus for bending a. similar section to that shown at (1 in 3 from an I-beam shown at. 0 In this-method, I run the section through ,thepass a to bendthe outer extremities of 2.3 (two ofthe flanges at-an angle of about 45 degrees, with relation to the web and ,tlanges, and then run the section through .the passe to bendthe extremitiesof the .other flanges in a similar -m-anner. The

315 blankis then runthrough passes 0" and 0 to bend the outer extremities of e the flanges another 4&5 degrees, so that the outer extremities of theflanges on opposite-ends of "the blankextend toward each other sub- 9 stantiallyparallel with the web andat an angle-of about 90 degrees to; the flanges.

In Figs'5- andfl, I haveshown other forms of apparatus for forming I-beamsections m ..and n it'rom a blank such as shown at ;.t5 .m,.by running itthrough passes m and .m or through passes a and n lnll g. 7 I haveshown at Ea blanksimilar to that shown R1166 1n F g. lg and e e 151M615: 7 3 2 5 e12.

;e 'e- -e 6 e e 6 e ands designate a number of other sections-wh ch may be formed from said blank, which difl'er f rom those shown n the variousiroll passes ,5 shown in Figs. l-to 6.

,InFig. 8, F designat-es a blank similar ;to .thatshown in Fig. 7.,with tl1e exceptiontha-t it only has; three flanges. These three flanges may be bent manner similar to three 9 ofthe flanges inthe section shown in Figs.

'lhetwo flanges of each of these stood that; the sections formed by any of the intermediate passes are adaptablefor -:use- {or 1various purposes. It will also be un derstood by those 'familiar with the art,'that various other sectionsthanthose shown in the drawings may be formed by this method.

In the above mentioned figures, I have; shown a plurality of sections which may be afOlFlllQd from the various blanks by means of thevarious steps set forth in the method of .roll bending sections, while running .the .sections through roll passes in which the webs a are maintained at .an angle of approximately 4-5 degrees to the axes of the rolls, so that'the rolls willoengage both sides of the web and both sides of the flanges which are being bent.

The advantages of my invention result from theprovision of itlllQllhOfl for bonding sections having a web and .a plurality .ott' flangesat each end of tl eweb, the flanges having one portion atan angle toanother portion thereof. Further, from the ,provision ofn'olls which are arrangedto engage both sides of the Web while. bending the flangesto form an Ivbeam from a rolled section,or section havin a--web and a plui wralityzofflanges ateachend thereof, each having t-wo portions at an anglezto each .other, and thereby avoid distorting the section.
