  • noun A weapon which throws or propels a missile to a distance; any firearm or instrument for throwing projectiles, consisting of a tube or barrel closed at one end, in which the projectile is placed, with an explosive charge (such as guncotton or gunpowder) behind, which is ignited by various means. Pistols, rifles, carbines, muskets, and fowling pieces are smaller guns, for hand use, and are called small arms. Larger guns are called cannon, ordnance, fieldpieces, carronades, howitzers, etc. See these terms in the Vocabulary.

  • noun (Chem.) a general name for a series of explosive nitric ethers of cellulose, obtained by steeping cotton in nitric and sulphuric acids. Although there are formed substances containing nitric acid radicals, yet the results exactly resemble ordinary cotton in appearance. It burns without ash, with explosion if confined, but quietly and harmlessly if free and open, and in small quantity. Specifically, the lower nitrates of cellulose which are insoluble in ether and alcohol in distinction from the highest (pyroxylin) which is soluble. See Pyroxylin, and cf. Xyloidin. The gun cottons are used for blasting and somewhat in gunnery: for making celluloid when compounded with camphor; and the soluble variety (pyroxylin) for making collodion. See Celluloid, and Collodion. Gun cotton is frequenty but improperly called nitrocellulose. It is not a nitro compound, but an ester of nitric acid.

  • noun a breech-loading gun or a group of such guns, mounted on a carriage or other holder, and having a reservoir containing cartridges which are loaded into the gun or guns and fired in rapid succession. In earlier models, such as the Gatling gun, the cartridges were loaded by machinery operated by turning a crank. In modern versions the loading of cartidges is accomplished by levers operated by the recoil of the explosion driving the bullet, or by the pressure of gas within the barrel. Several hundred shots can be fired in a minute by such weapons, with accurate aim. The Gatling gun, Gardner gun, Hotchkiss gun, and Nordenfelt gun, named for their inventors, and the French mitrailleuse, are machine guns.
  • noun (Naut.) to blow a gale. See Gun, n., 3.
