BUILT-UP GUNS. Recently invented guns of great strength, specially adapted to meet the requirements of rifled artillery and of the attack of iron plating. They are usually composed of an inner core or barrel (which may be of coiled and welded iron, but is now generally preferred of tough steel), with a breech-piece, trunnion-piece, and various outer strengthening hoops or coils of wrought iron, shrunk or otherwise forced on; having their parts put together at such predetermined relative tensions, as to support one another under the shock of explosion, and thereby avoiding the faults of solid cast or forged guns, whereof the inner parts are liable to be destroyed before the outer can take their share of the strain. The first practical example of the method was afforded by the Armstrong gun, the "building up" which obtained in ancient days, before the casting of solid guns, having been apparently resorted to as an easy means of producing large masses of metal, without realizing the principle of the mutual support of the various parts.
