IMPROVED PILE IOR WROUGHT-IRON BEAMS OR GIRDERS.

TO ALL WHOM IT hIAY CONCERN:

Be it known that we, GEORGE WAL'rnns and Titou/lsv Sunrrnr., both of Phcenixville, Chester county, Penn- Sylvania, have invented certain improvements in Piles or Fagots for llrought-Ironl Beams or Girders; and we' do hereby declare the following to be a full, clear, and exact description of the same.

Our invention consists of a pile or fagot, Afor wrought-iron beams -or girdcrs, composed of one or more bars for the web, and any appropriate number of bars for the flange or flanges,l the said bars being arranged and permanently secured by bolts or rivets in the manner'and for the purpose of effecting the advantageous results described hereafter.

In order to enable others skilled in the art to practise oui invention, we will n'ow'proceed to describe theA mode of carrying the same-into effect, reference being had to the accompanying drawing, which forms a p'art of this specification, and in which- Figure 1 is .a transverse section of our improved pilcior fagot for wrought-iron beams or gil-ders.

Figure 2, a'side view partly in section, and

Figures 3, 4, 5, 6, 7, and 8 illustrate our improvement as arlied to fat-gots for forming bars of dilerent transverse forms.

Similar letters refer to similar parts throughout the several views.

On reference to figs 1 and 2, a ct represent two bars placed side by side,` and cut to the desired length of the'pile or fagot, these two b ars forming the web, on cach side and near the upperl edges of'which are arranged the bars b, c, and d, permanently secured together by bolts or rivets c. The middle bar c is made in sections or lengths arranged at such a distance; apart fromeach other as to permit the passage between them of bolts or rivetsf, which also pass through holes in the web, and serve to secure the latter permanently to the bars b, c, and d, which form the flanges. The pile, which approximates in shape to an H-beam, is now placed ina furnace and reduced to a welding heat, to be subsequently converted into a beam of the desire action of the usual rolls. I A pile or fagot, constructed as above described, will retain its shape while it is in the furnace, and the bars being firmly bound together no cinder or other `1`mpuritics can be lodged between them, and, being all plain, whatever impurities there may be in the iron-are easily worl-:ed out.

Alhe beam rolled from apile or fagot composed of bars arranged and secured together as described, is more uniform, solid, and of better finish than bea-ms rolled from ordinary agots` i It will bc understood that the web of the pile maybe composed of a single bar, or of more than two bars; three bars or more than three bars, however, being necessary for each flange, so that one ofthe inside bars may be arrangedin sections apart from etch other to azlmit the` transverse rivets or bolts It will also be understood that ourI invention may be applied' to the construction of piles for T-beams or girders, as shown in tig. 3, or to piles for angle-beams, as seen in fig. d, or to piles of the character illustrated in figs. 5, 6, 7, and S.

We claim as our invention, and desire to secure by Lettcrs'P-atcnt- A pile or fagot, for wrought-iron beams or git-ders, the., composed oi' one or more bars for the web, and three or more bars for each flange, when the said bars are arranged and permanently secured together by bolts or rivets, as and for the purpose described- In testimony whereof` wehave signedour names to this specification in the presence of two-subscribing witnesses.

GEORGE WALTERS, THOMAS SHAFFER.
