THOMAS C. CLARKE AND ADOLPHUS BONZANO, OF PHILADELPHIA7 PA.
IMPROVEMENT IN `BRIDGE-(50NN ECTIONS.
Specification forming part of Letters Patent No. 130,479, dated August 13, 1872.
and ADoLrHUs BoNzANo, of the city of Philadelphia, in the State or Pennsylvania, have invented certain new and useful Improvements in Connections or Fastenings for Bridges of Iron or Steel; and we do hereby declare the following to be a full, clear, and exact description of the same.
Our invention consists of a block or connecting-piece having a projection for the passage of tie-rods,and a socket foi` the reception of the end of a transverse strut, so arranged that the saidstrut shall resist the strains imparted through the tie-rods.
In the accompanying drawing, Figure lisa plan view, showing our connecting-piece applied to the upper chord system of an iron bridge; Fig. 2, a side view; and Fig. 3, an elevation, partly 'in section.
The connecting-piece A consists of a cast- Y projection D extends into and is riveted tothe upper end of a hollow post, E; the adjacent ends of two hollow sections, C C, of the top chord in like manner receive and are riveted to the projections B B; and one end of the transverse strut G rests in the socket F. In order to insure a firm and positive bearing of the connecting-piece against the strut G, the projection M is perforated for the passage of two diagonal tie-rods, L L, each of which extends across the-vertical axis of the projection, one being above the other, as shown in the drawing, and both being very nearly on the saine horizontal plane as the axis of the strut. Owing to this arrangement the strains, applied through the tie-rods to the projection M, are sustained by the strut G. rIhe said proj ection can, therefore, be much less in dimension than it would be if the strut were dierently situated and the entire strain had to be resisted by the projection. In the connectingpiece is a transverse opening, H, for the recep-n tion (in the present instance) of the throughpin K, to which the main and counter diagonals I J are attached.
The projections DB, instead of being annular may be octagonal or of other form, to coincide with chord-pieces or posts of corresponding sectional form.
