SPECIFICATION forming part of Letters Patent N 0. 636,521, dated November '7, 1899.

Application filed June 22 1899. $eria1 No. 721,447. (No model.)

To all whom it may concern.-

Be it known that I, J OSEPH GUEST, a resident of Homestead, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Rolling Metal; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to the making of angle-bars and plates therefrom, its object being to provide for the rapid reduction of the metal from large ingots or billets, so as to produce with few passes two angle-bars at one time, and in addition, if desired, to provide for the formation of two flat plates or bars from each such angle, so providing for the rolling of this class of articles by few passes.

The invention consists, generally stated, in

reducing a square billet first to star shape and then shearing the star-bar into two angle-bars, this being preferably accomplished by forcing the opposite faces of the opposite flanges into line with each other and then shearing in line with such opposite faces of ing the different sections of the metal in course of reduction, and Fig. 10 is a face view of rolls suitable for forming the same.

Like letters and numerals indicate like parts in each of the figures.

In practicing the invention as shown in the drawings the square ingot or billet a is rolled to substantially the form shown in Fig. 2, having its outwardly-extending flanges b, with partially-developed flanges c, midway on each side thereof, and in the next pass the partially-developed flanges care brought into flange shape, producing a star-bar, as shown in Fig. 3, having flanges at right angles to each other, as shown at d d d (1 By one or more passes the flanges on opposite sides of the bar are drawn out of line with each other, as shown in'Fig. 5-that is, say the flange on one side is forced downwardly and the flange on the other side forced upwardly until the upper face e of one flange d is brought into line with the lower face f of the flange d, the flanges d and (1 remaining in line with each other. The next pass of the rolls is constructed so as to sever the starshaped bar so formed along the line of the faces of of the flanges d d and so form the two angle-bars, one being composed of the flange d and the flange d and the other composed of the flange d and the flange (1- It thus requires five or less passes to reduce the metal contained in the square ingot into two separate angle-bars, while in so rolling the same the metal contained within the bars in their different forms is so disposed as to balance each other and prevent the bar from stretching unevenly and so being forced out of straight or proper line. In so reducing the bar it may be desired to employ an intermediate pass, suchas shown in Fig. 4, before bringing the blank to the shape shown in Fig. 5 and ready to be severed into two angle-bars. The angle-bars so produced can be used as angle-bars, being given one or more finishing passes, if necessary, or can be utilized in forming other shapes, such as by spreading out the angle-bars, as shown in Fig. 7, and then forming flat plates or skelp therefrom, as shown in Fig. 8, or, if flat plates or bars of less width are desired, the anglebars, such as shown in Fig. 6, can be severed close to the connecting-angle k and two bars Z m produced therefrom, as shown in Fig. 9, in this way providing for the formation of four or more rectangular bars from the original billet by very few passes.

In Fig. 10 are shown rolls with an arrangement of passes suitable for practicing the method above described, the desired passes for such work being shown at 1, where the billet is rolled to the form shown in Fig. 2, 2 and 3, where-the star-bar is produced, and 4, where the opposite flanges are drawn out of exact line with each other-that is, so that their opposite faces 6 and f will be drawn into line with each other, as shown in Fig. 5-5 showing the pass for severing the star-bar into two angle-bars. The passes 6 and 7 illustrate the flattening of said bar to produce wide plate or skelp, while the pass 8 provides for the severing of the an gle-bar into two narrow bars which can be finished, if desired, in the pass 9.

The ad vantages of the invention should be apparent to thoseskilled in the art, as it provides for the rolling of two angle-bars at one time and overcomes the necessity of so great reduction from the original billet, providing for the production of such angle-bars in five or less passes and providing for the production of two flat bars from each angle by a single extra pass or for the opening out of the angle-bar into flat plate or skelp by one or more single passes. The cost of rollingis therefore very materially reduced.

hat I claim as my invention, and desire to secure by Letters Patent, is-

1. The method of rolling angle-bars, consisting in reducing a square billet to star shape and then shearing the star-bar into two angle-bars, substantially as set forth.

2. The method of rolling angle-bars, consisting in reducing a square billet to star shape and forcing the opposite faces of two opposite flanges into line with each other, and then shearing along the line of said faces through the other flanges of the star-bar, so forming two angle-bars, substantially as set forth.

3. The method of rolling flats, consisting in reducinga square billet to star shape, and then shearing the star-bar into two anglebars, and then shearing the angle-bars so produced along the line of the angle and so forming two flat bars from each angle, substantially as set forth.

4. In the rolling of angle-bars, rolls having passes arranged to form a star-bar, and a pass to shear the same at its meeting angles into two angle-bars, substantially as set forth.

5. In the rolling of angle-bars, rolls having preliminary passes arranged to form a starbar, then a pass arranged to force the opposite faces of two opposite flanges into line with each other and a succeeding pass arranged to shear through the bar in line with said faces, substantially as set forth.

6. In the rolling of angle-bars, rolls having passes arranged to form a star-bar, and a pass arranged to shear through such star-bar at the meeting angles and form two angles, and a pass to shear through such angle-bar close to the angle thereof, substantially as set forth.

'7. In the rolling of angle-bars, rolls having passes arranged to form a star-bar, and then a pass arranged to shear through such starbar along the line at the meeting angles and form two an gle-bars,and then passes arranged to flatten out such angle-bar into flat plate, substantially as set forth.

In testimony whereof I, the said JOSEPH GUEST, have hereunto set my hand.
