Not illustrated. 1865 Excerpt: ...aqueduct with a double stirrup of 1 in. round iron, mounted on a small saddle of cast iron, which rests on the cable. Into these beams, wooden posts 7 x 7 in. at top, and 7 x by 14 in. at bottom, are mortised. These posts are the side supports of the water-trunk, which is of wood, 1140 ft. in length, 14 ft. wide at bottom, and 16 ft. wide at top, and 8 ft. deep. The sides and bottom are composed of a double course of 2g in. white pine, placed so that each course crosses the other diagonally at a right angle. The extremities of the cables do not extend below the ground, but are connected with anchor-chains which, in curved lines, pass through the masonry of the abutments. The bars of these chains average 1 x 4 in., and from 4 to 12 ft. in length. They are formed of boiler scrap iron, and forged in single pieces without welds. The extreme links are anchored to cast-iron plates 6 ft. square. The total length of each cable and its chains is 1283 ft., and the weight of both cables.110 tons. The weight of water in each span (4 ft. deep in the trough) is 295 tons. The total solid section of anchor chains is 72 superficial inches. Deflection of chains, 14 ft. 6 in. Elevation of pyramids above piers, 16 ft. 6 in. The tension of each wire is 206 lbs., while its ultimate strength will be 1100 lbs. 381. Cast-iron pipes are now universally employed for the conveyance of water. They are formed with socket ends, so that all necessary motion is permitted according to the expansion and contraction of the metal, caused by variations of temperature. Until the commencement of the present century all the water supplied by companies to London was conveyed in pipes bored out of elm, and at that time the New Kiver Company had 400 miles of these wooden pipes in use. The general use...
