IMPROVEMENT IN CONNECTIONS FOR WROUGHT-IRON BEAMS AND COLUMNS.

Specification forming part of Letters Patent No. 140,455, dated July 1, 1873 application filed April 26, 1872.

To all whomt't may concern:

Be it known that I, ADOLPHUS BONZANO, of Phoenixville,Pennsylvania, have invented an Improvement in Wrought-Iron Structures, of which the following is a specification:

My invention relates to a mode (too fully described hereafter to need preliminary descript-ion) of connecting together wrought-iron beams and columns, my invention being applicable to bridges, viaducts, warehouses, and other structures of which columns and girders or beams form a part.

Figure 1 is a sectional plan of a wroughtiron beam and column constructed and arranged in accordance with my invention; Fig. 2, a sectional elevation on the line 1 2 of Fig. 1, looking in the direction of the arrow 1; Fig. 3, a side view of part of the device shown in Fig. 1, looking in the direction of the arrow 2 Fig. 4, a modification of part of the device shown in Fig. 1; Figs. 5 and 6, views showing a modification of my invention.

In Figs. 1, 2, 3, and 4 the column is made of flanged bars a, similar to those described in the patent granted to S. J. REEVES on the 17th of June, 1862, the said flanged bars being arranged a short distance apart from each other for the admission between them of bars 12, according to one modification illustrated and described in the aforesaid patent. These bars I) extend from end to end of the column, excepting where beams have to be connected to the latter, and where the beams occur the bars b are discontinued at opposite sides of the column for the admission of a plate, B, which is riveted or bolted to the flanges of the bars composing the column, and forms an integral part of the latter. This plate B projects beyond the flanges of the column on each side of the latter, one plate meeting and coinciding with the web of a beam, D, and the other coinciding with the web of the opposite beam D, these beams being, in the present instance, of the well-known Phoenix pattern. Each end of the plate B is connected to the adjoining beam by splicing-plates d and d, which fit snugly against and are riveted or bolted directly to the web of the beam and to the plate B.

It will be noticed that the plate B is deeper than the beam to which it is connected. This arrangement may be adopted when the plate is comparatively thin ,-as thin, for instance, as the web of the beam-so that whatever strength may be lost in the plate by making it so thin may be compensated for by its depth. A plate, B, however, thicker than the web of the beam, and of the same depth as the said web, may be passed through and secured to the column, in which case the splicing-plates may be bent to fit both the plate B and the web of the column, as shown in Fig. 4.

In Fig. 5 two splicing-bars, B and B, pass through the column, and are fitted and riveted or bolted to the webs of the beams D and D, the said splicing-bars resting on fillingpieces m arranged at intervals between the flanges of the column-bars, and the splicingbars may be bolted or riveted to the flanges of the column-bars, in which case, however, filling-pieces It should be introduced between the said splicing-bars where the flanges occur, as shown in Fig. 5.

In constructing the column, Figs. 5 and 6, I prefer to use solid fillin g-pieces m m arranged at frequent intervals, each piece being long enough to receive two bolts or rivets, by which they are secured to the flanges of the columnbars. (See Fig. 6.)

My invention may also be carried out in connection with the column for which Letters Patent were issued September 24, 1872, No. 131,502, to T. 0. CLARKE, assignor to CLAR E, REEVES & 00., the said column consisting of flanged bars similar to those described in the aforesaid patent of REEVES, but some of those bars being arranged in short lengths at intervals so as to present a row of openings, through any of which the splicing-bars may be passed;

in fact, my invention may be adopted in connection with any wrought-iron column having openings through which the splicing-plates can be passed.

It-will be evident that wrought-iron beams and columns may be connected together economically, both as regards material and workmanship, according to my invention, which may be adopted with advantage in the con- In testimony \vhereofl have signedinyna-me struction of bridges,vi2tducts, Warehouses, and to this specification 1n the presence of two subother structures of which columns or posts scribing witnesses.

and girders form a part. AD OLPI-I 'S BONZANO.

I claim as my invention- Vitnesses: The combination described of Wrought-iron P. G. CAREY,

columns, beams, and splicing-burs. JOHN GRIFFIN.
