Awards in Section B.
No. 647, p. 247. The Derwent Iron Company, New-castle -upon-Tyne. 1. Rolled iron plates from 17 to 20 feetlong for ship-building purposes and for the sway beamsof engines. 2. Rolled keel iron, a railway bar, measuring66 feet 9 inches in length. A great importance has oflate years been given to the manufacture of wrought ironin large masses by the increased scale, which every formof construction of iron is assuming. The limited dimen-sions of the wrought-iron plates, sway-beams, shafts, bars,&c., with which the engineer has to work, are indeedamong the chief obstacles to construction in iron. Al-though much progress has of late years been made in thescale on which it is wrought, yet these are believed to beamong the largest specimens ever produced in their re-spective departments of manufacture, and the Jury wereunanimous in their recommendation of a Council Medalto the makers of them. They regret that this recom-
mendation, not having been adopted by the Council ofChairmen, they have only the Prize Medal to award tothem.
No. 543, pp. 241, 242. Patent Shaft and AxletreeCompany, Brunswick Iron Works, Weduesbury. 1.' Spe-cimens of iron of their manufacture. 2. Patent railwaycarriage axles and other axles, with illustrations of theirprocess of manufacture. 3. Patent links for suspensionbridges, rolled at a single heat.
To form these axles, plates of iron are placed togetherlike the radii of a circle, and tied with pieces of wire.In this state they are heated to a welding heat and thenplaced under forge-hammers, which have, together withtheir anvils, circular cavities of the dimensions of theaxle to be formed. The fibrous quality of the ironderived from the plates, which are welded together toform it, thus remains unimpaired in the forging. APrize Medal has been awarded for these articles.
No. 641, p. 247. Coalbrook Dale Company, Stafford-
