Laird, J. 1869 (Patent <strong>No</strong>. 94,321): Radial verticals. Diagonal cross-bracing. Trussed arch-chord.<br />
Laird, J. 1869 (Patent <strong>No</strong>. 94,322): Radial verticals. Diagonal cross-bracing.<br />
Parker, C. 1869: Suspension truss superimposed on bowstring.<br />
Hammond & Abbott 1870 (Patent <strong>No</strong>. 102,392): Tubular arch top-chord. Web diagonals and radiating<br />
verticals attach to flanges of top-chord sections.<br />
Hammond & Abbott 1870 (Patent <strong>No</strong>. 102,393): Tubular arch top-chord. Web diagonals and radiating<br />
verticals penetrate the top chord.<br />
# McCurdy 1870 (Patent <strong>No</strong>. 104,867): Bottom tie is a wire cable. Web contains only verticals.<br />
McCurdy 1870 (Patent <strong>No</strong>. 104,868): Web has a single vertical at mid-span, no diagonals. Also could be<br />
considered a curved-king-post truss.<br />
# Miller, M. 1870: Multi-plate arch-chord. Web of radiating pipe sections.<br />
Moseley 1870 (Patent <strong>No</strong>. 103,765): Vertical suspenders. Use of diagonals “when necessary” would make it<br />
a truss.<br />
Moseley 1870 (Patent <strong>No</strong>. 106, 855): Diagonal tie from mid-point of bottom chord to quarter-span on arch<br />
chord. Vertical ties. Use of cross bracing option between ties would make it a truss.<br />
