    • n cannon An engine, supported on a stationary or movable frame called a gun-carriage, for throwing balls and other missiles by the force of gunpowder; a big gun; a piece of ordnance. Cannons are made of iron, brass, bronze, or steel, and of different sizes, carrying balls from 3 or 4 pounds weight up to 2,000 pounds and more. The caliber or power of cannon may be expressed by the weight of the shot fired: as, a 32-pounder; by the diameter of the bore: as, 8 12-inch gun; or by the weight of the gun itself: as, an 8-hundredweight gun; a 25-ton gun. Before the introduction of armor-plating, the naval guns in use in line-of-battle ships and frigates were 68-pounders (95 hundredweight), 8-inch shell-guns (65 hundredweight), and 32-pounders (42 to 58 hundredweight). Now ships are spoken of as armed with 6½-, 12-, 18-, 25-, 38-, etc., ton guns, the 18-ton gan throwing 400-pound projectiles, and the 25-ton gun 600-pound, and so on, the weight of the ball rising with the weight of the piece. Cannon weighing more than 100 tons have recently been constructed. The 100-ton gun is charged with 340 pounds of powder, and discharges a bolt of steel or chilled iron weighing 2,000 pounds. Cannon of the smaller calibers are mounted on wheeled carriages for service as field-pieces. In the United States army the guns in service are 8-, 10-, 13-, 15-, and 20-inch smooth-bore Rodman guns, and 3-, 3.2-, 4.5-, 8-, and 12-inch rifled guns. The American 8-inch rifled gun is the 10-inch Rodman smooth-bore, lined with a coiled wrought-iron or steel tube. The 3.2-inch gun is a steel field-piece. In the United States navy, 6-, 8-, and 10-inch steel guns have been adopted for the cruisers of recent design. The principal parts of a cannon are: 1st, the breech, which is the mass of solid metal behind the bottom or end of the bore, and extending to the base-ring; 2d, in muzzle-loading cannon, the cascabel, a projection in rear of the base-ring including the knob, the spherical part between the knob and the base-ring being called the base of the breech; 3d, the reinforce, the thickest part of the cylinder, extending from the base-ring forward; 4th, the trunnions, which project on each side, and serve to support the cannon; 5th, the bore or caliber, the interior of the cylinder, wherein the powder and shot are lodged, and which may be smooth or rifled, though rifled cannons have virtually superseded the smooth-bores; 6th, the muzzle or mouth of the bore. Cannon are often made so as to be loaded at the breech, various devices being employed to effect this object. Cannon were formerly classed as whole cannons, demi-cannons, culverins, sakers, etc., but are now classified as guns, howitzers, carronades, and mortars; also as field-, mountain-, coast-, sea-, and siege-guns. See gun.
