carriage of a gun

The Sailor's Word-Book

The frame on which it is mounted for firing, constructed either exclusively for this purpose, or also for travelling in the field. Carriages for its transport only, are not included under this term. The first kind only is in general use afloat, where it usually consists of two thick planks (called brackets or cheeks) laid on edge to support the trunnions, and resting, besides other transverse connections, on two axle-trees, which are borne on low solid wooden wheels called trucks, or sometimes, to diminish the recoil, on flat blocks called chocks. The hind axle-tree takes, with the intervention of various elevating arrangements, the preponderance of the breech. The second kind is adapted for field and siege work: the shallow brackets are raised in front on high wheels, but unite behind into a solid beam called the trail, which tapers downwards, and rests on the ground when in action, but for travel is connected to a two-wheeled carriage called a limber (which see). Gun-carriages are chiefly made of elm for ship-board, as less given to splinter from shot, and of oak on shore; wrought-iron, however, is being applied for the carriages of the large guns recently introduced, and even cast-iron is economically used in some fortresses little liable to sudden counter-battery.
