TO ALL WHOMIT MAY-CONCERN:

Be it known that I, WYATT W. MILLER, of Safe Harbor, in the county of Lancaster,.and State of Pennsylvania, have invented anew and improved Pile for Rolling Beams; and I do hereby declare that the following is a full, clear, and'exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification. I

This invention relates to a new method for forming piles from which to roll large or small double-flange beams, such as are used in fire-proof buildings, roofs, bridges, Kic- Piles are made in'thc ordinary way, used only for the smaller sizes of beams, up to about nine inches in height. The largersizes are rolled from special piles, and my invention is intended to represent the simplest form for a pile for such double-flanged beams. In order toroll large sizes of beams it is necessary to approximate in the pile to the form of beam to he rolled, and it' isalso necessary to so-construct the pile that it may be readily handled in charging in the heating-furnace, and drawing therefrom, and unless it is firmly put together it will not bear handlingv In the annexed drawing my invention is illustrated-.-

Figure 1 being a side view of my improved pile, and

Figure 2 a vertical cross-section of the same, the line .1: ng, fig. 1, indicating the plane of section.

Similar letters of reference indicate likepar ts. I

On rolling an iron her through the last groove of the rollers, I produce the same in the shape shown at a a in figs. 1 and 2, which .is u flat bar, providedwitha' flange, I), projecting from the centre of one face, as shown. These bars a a are thcn, hy any suitable device orimchanism, provided with holes, which are punched through the some at the required distances, and the liars are cut to the required length. 'The bars a a form the top and bottom of the pile; The web is formed of one or more flat bars 0 c, which are arranged vertically between the bars a a, as shown, their thickness nearly corresponding with that of the flange b, as shown in the drawings. On each side of the bars a c are arranged upright plates (Z d, which are rolled so as to have small flanges d" d along their upper and lower edges, as shown. The bars c and cl are'also out to the proper length, and arranged in their respective places, and tho whole pileis then held together by means of' hook-headcd bolts or rivets e e, which are passed through the holes in the bars a a, which are mentioned above For making a beam, a bar, a, is laid down flat, the bars (Z11 are then placed upon it, and between the latter are placed the bars 0 c, and then the top bar a is laid on top, and the two bars a a are then secured to the flanges of the bars IJZ cl by means of the hook-headed bolts or rivets. The whole pile is thus rendered solid and easily handled, and is then charged in a heating-furnace and brought to a welding he'at preparatory to being rolled into a beam between "ollers, the construction and operation of which may vary, and is not part of my invention.

What I claim as new, and desire to secure by Letters Patent, is-- The pile, constructed asdescribed and shown, consisting of the bars a having flanges b, bars-d having flanges (Z, hooked bolts 0, and the tint lHtlS a, as and for the purpose pecified;
