Specification of Letters Patent.

Application filed June 30,

1905. Serial No. 267,833.

To all whom it may concern:

, Be it lmown that I, JAMES E. YORK, a citizen of the United States, residing in the borough 'of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in the Process of Making Shapes for Columns and the Like, of which the following is a specification.

This invention aims to provide a simple and convenient method of forming steel shapes for columns and the like, which process lends itself readily to the formation of shapes now. in use, and by which also certain shapes may be made which have been hitherto impossible.

The special advantage of the process'is in the facility with which the desired shapes {nil-y'- be rolled from old rails, beams or the Other advantages are referred toin detail hereinafter.

The accompanying drawings illustrate embodiments of the invention. 1

Figures 1, 2, 3 and 4 illustrate the successive steps of transforming a part of an old rail into a substantially semi-circular flanged shape by a combined rolling and stamping operation; Figs. 5 and 6 illustrate the method of forming another shape by a combined rolling and bending operation; Figs. 7 to 15 inclusive illustrate various shapes which may be rolled bythe new rocess. -Figs1 16 and 17 are elevations o the columns showing the particular constructions.

An important feature of the invention is in the rolling of the flange or head of a rail, or ofany other elongated, flanged shape laterally, so as to spread such flange into a wide thin plate, with a stiffening flange (originally the web) at an intermediate point. In making more complicated shapes it is proposed in addition to press or stamp or otherwise bendthe central portion or the edge of sucha plate to bring it to the desired shape, and

to form the flanges thereon for stifl'ening the edge ,or fastening it to an adjacent section.

In connection with the rolling orthe stamping operation, the plate may be embossed by r suitably shaping the die so as to give it any Patented Aug. 27, 1912. I

ornamental or useful configuration desired.

Referring now to the drawings, the oldrail shown in Fig. 1 and composed of a web A, a base or flange B, a head C which is in effect a thick flange Worn to a rather irr egular top face, may be divided, preferablyby a rolling operation, into the member shown in Fig. 2 comprising a head C intact, and a flange D originally constituting a part of the web of-therail. The shape shown in Fig. 2 may then be transferred to a machine such as is illustrated in my applications Numbers 177,989 and 236,354 'filed respectively October 21, 1903 and December 10, 1904, and laterally rolled to spread the head G into a wide thin plate E. The spreading is accomplished by laying the member on a bed F of suitable configuration, and rolling laterally over the member a pressure roller G back and forth a sufficient number of times to secure the desired spreading, the portion of rail being first heated to the desired extent. The plateE with the flange D may thereafter be transferred to a bending or stamping machine comprising a lower die H and an upper die J of suitable config' this being a' shape which is very useful, and

also very difficult orimpossible to obtain by the usual rolling processes. In addition, the extra rolling of the metal increases its quality, especially the lateral rolling of one portion, while another portion, the flange D,

has been rolled longitudinally.

By slight variations of the operations described a great number of final shapes may be obtained,,some of which are diflicultand others impossible to obtain in any other way. For example .it would be impossible to longitudinally roll wide thin flanges such as constitute the plate E or the plate N hereinafter referred to. Such wide flanges I ducing an ideal section for columns made of a single piece, and having a very excellent distribution of the material toresist column strains. In fact in 'a single integral member there are obtained all the advantages of proper distribution of the metal and com enien'c'e of making joints, which have made a similar built-up section 'perhaps the most popular among engineers. This built-up section is formed ordinarily of four Z-bars riveted to a'central late. This figure illustrates in a most strililing way the advantages of the present process. r

Fig. 7 illustrates a section of the complete column made up of two of the members indicated at Fig. 4, with the flanges L riveted to 851611 other, thus providing a section simi-' lar to the well-known Phenix' section consisting of a ring with radial flanges. The

ordinary Phenix section is made up of four or six separate arcs, while according to the present invention it may be made up of only two such arcs.

Fig. 8 illustrates a slight modification of the shape of Fig. 7, the plates K being angular instead of circular so as to form an octagonal column.

Fig. 9 illustratesa column section built upof members of two different styles. In one style the web A is intact and the plate N is formed from the head. or the base, while the thicker plate N at the opposite side is formed from the base orthe head as the case may be. In the other style the plate N is formed of either the head or base of the rail,

and a thin flange A is formed by rolling out the web of the rail, or by the use of a deeper rail or 'I-beam or the like.

Fi 10 indicates a shape similar to that of Flg. 7, but in which the plate K is of.

such shape as to constitute a square column instead of a circular one; It-is understood that the embossing indicated at M in Fig. 7 may be added or not at will.

Fig. 11 indicates. a variation of the shape of Fig. 10 in which the flangeD extends into the interior of the column instead of outward, thus economizing space without losing very much in the strength of the sec-. tion.

Fig. 12 is a variation of Fig. 7 in which the complete column will 'be hexagonal instead of circular. A

Fig. 13 is avariation of Fig. 7 which the flange D is on the inside to economize space.

Fig. 14 illustrates a very exbellentsection which maybe made of two identical members having central wide flanges A, and: plates N with flanges O" bent downward, that is to say, at the same side of the web A;

the two menibers being riveted to each other back to back.

Fig. 15 lllustrates a direct variation of Fig. 6 in which the flanges 0 instead of being bent outward are bentinward toward each other, the proportions of the parts being such as to maintain a substantially square plane. L

The operation of spreading the flanges to form the plates N in Fig. 5 may be stopped at any suitable point so as to obtain, an I- beam, or more accurately an H-beam with very wide thin flanges of uniform thickness throughout their width, such as could not possibly be rolled by any other process. Such a shape would be extremely useful either as an integral simple column'section, or as a beam.

By suitably ribbing or grooving the roll and bed or the dies of Figs; 3- and 4., Sockets not to be understood as thereby waivlngmy right to claim the same in a separate application.

ticularity of detail certain specific embodiments of the invention, yet it is not to be understood therefrom that the invention is limitedto the particular embodiments disclosed, various modifications of the process, I and of the several products, may be made by those skilled in the art,.w ithout departure from the invention.

What I claim is tion having a longitudinal rib and longitu dinal flanges which consists in taking a rail head with part of the web thereon and spreading, fianging and concaving the metal of said head;

2. The process of forming a column section having a. longitudinal rib and longitu dinal flanges which consists in an Though I have described with great par.-

- 1'15 1. The process of forming a column secelongated shape having a head and a rib and spreading, flanging and concaving the metal of said head. 7

3. The process of forming an elongated structural shape having a longitudinal projection intermediate of its edges and having longitudinal flanges along its edges, which consists in taking an elongated shape having a head and a longitudinal projection and In Witness whereof, I have hereunto signed my name in the presence of two subsoriblng Witnesses.
