CARRIAGE of a Cannon, the frame or timber-work on which it is mounted, serving to point it for shooting, or to carry it from one place to another. It is made of two planks of wood, commonly of one-half the length of the gun, called the checks, and joined by three wooden transoms, strengthened with three bolts of iron. It is mounted on two wheels, but on a march has two fore-wheels with limbers added. The principal parts of a carriage are the checks, transom, bolts, plates, trainbands, bridges, bed, hooks, trunnion holes, and capquarre.
