ro ALL wHoM Ir MAY coN'cnRN:

Be it known that we, Geenen WALrnns and Tuonns Sunrrnn, of Phoenixville, Chester county, Pennsyl Vania, have invented an improved Iile or Fagot for Wrought-Iron Beams or Girdcrs; and we do hereby declare the following to be a full, clear, and exact description of the same.

i Our invention consists of a pile or fagot (for wrought-iron beams or gil-ders) composed of one or more bars -for the web, and one'or more bars for the flange or flanges, the said bars being arranged and permanently secured together byvbolts or rivets, in the manner and for the purpose of effecting the advantageous results described hereafter. i

In order to enable others skilled in the-art to apply to practice our invention, we will now proceed to describe thev mode of carrying the same into eifect, reference being had to the accompanying drawing, which forms a part of this specification, and in which- Figure 1 represents a transverse section of an improved pile or fagot forwrought-iron beams or girders.

Figure 2, a side view 0f the same.

' Figures 3 and 4, modifications; and

Figures 6, 7, 8, 9, 10, and 11 illustrate our improvement as applied to the construction of fagots for beams of different transverse shape.

Similar letters refer to" similar parts throughout the several views.

On reference to figs. 1 and 2, a, b, and c represent three bars placed side by side, and cut to the desired length ofthe pile` or fagot, these bars forming the vertical web, against the upper and lower edges of which are placed two bars, d and e, the latter being punched to receive bolts or rivets ff, arranged on cach side of and close to the web, and serving to secure the said bars d and e to the web, the bars of the latter being secured together by the transverse bolts it L. The pile, which approximates in shape to an H beam, is now placed in the furnace, there reduced to a welding heat, and then converted into a beam of the desired form and size by the action of rolls. v l

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 impurity can be lodged between them, and, being all plain, whatever impurities there may be in the iron arc easily worked out. The beam rolled from a pile or fagct composed of bars arranged and secured together as'described, is more uniform, solid, and of better finish than beams rolled from ordinary fagots. When three bars, a, b, and c, are used for the web, the middle bar, (i, may be made insections, arranged so far apart as to permit a vertical bolt, f, iig. 3, to pass between them, the bolt or rivet in this case taking the place ofthe two bolts or rivctsfg in fig. Vv1. The bolts or rivets on the outside of thc web are indispensable when 'the latter is composed of one or two bars only, bolts between vthe bars being available only when the web is composed of three or more bars, but the result as regards the binding ot' the transverse to the vertical bars is the same in both eases. Vertical belts or rivets,f, may be arranged to pass, some through and lseine on each side of the web. In some instances we make the web in thcmnnner .shown in tig. 1', that is, of' three vertical ba'rs, a, b, and e, and a longitudinal solid bar, a', placed on the top of the vertical bars. boltsfpassing through this bar x and between the sections of the middle bar I). The remaining figures, G, 7, S, 9, 10, and 11, explaining the application of our improvements to girders of different transverse forms, will be readily understood without explanation.

We claim as our inventiom and desire tofsecure by Letters Patent- A pile or fagot, v(for wrought-iron beams, girders, &c.,) composed of cnc or more bars for the web, and any desired number of'bars-fory the flange'or flanges, when t'hc said bars arc arranged and permanently secured together by boltsor rivets, as and for the purpose herein set forth.
