1851 Great Exhibition: Official Catalogue: Class VII.: John Henry Clive

41. CLIVE, JOHN HENRY, 12 Stanhope Place, Hyde Park, and Tunstall, Staffordshire — Inventor.

An illustrative model of a bar-trellis suspension bridge, to make a more secure and cheap roadway over rivers, without obstructing the navigation. The greatest part of the weight is laid on the lower parts of the suspension towers, by tapering the construction throughout from the base, beginning with strong suspending bars, and decreasing their strength to the summit, so that the tops of the towers shall have the least possible weight upon them, trussing and bracing together the suspension bars. The shortest suspension bars being made the heaviest, and the longest bars the lightest, without affecting their efficiency, each being constructed so as to be equal to its task, expense is saved by lessening the quantity of material to be used, and undulation and lateral motion as in chain bridges avoided, the bracing and trussing giving rigidity and a united hold.
