Truesdell truss

Lucius E. Truesdell patented a cast iron and wrought iron truss design in 1859. The main point of his patent was in how the diagonals in a lattice-type are fastened together. Truesdell felt the holes through the truss members necessary for fastening them together caused an unacceptable weakness. His solution was to have the overlapping diagonals bent at the intersection so the two pieces would interlock. A cast iron clamp holds the diagonal together. His design was awarded patent number 24068. In appearance, the Truesdell truss looks like a triple-intersecting warren with verticals.
