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.
[1913 Webster]

cannon.
[1913 Webster]

3. pl. (Naut.) Violent blasts of wind.

Note: Guns are classified, according to their construction or
manner of loading as {rifled} or {smoothbore},
{breech-loading} or {muzzle-loading}, {cast} or
{built-up guns}; or according to their use, as {field},
{mountain}, {prairie}, {seacoast}, and {siege guns}.
[1913 Webster]

{Armstrong gun}, a wrought iron breech-loading cannon named
after its English inventor, Sir William Armstrong.

{Big gun} or {Great gun}, a piece of heavy ordnance; hence
(Fig.), a person superior in any way; as, bring in the big
guns to tackle the problem.

{Gun barrel}, the barrel or tube of a gun.

{Gun carriage}, the carriage on which a gun is mounted or
moved.

{Gun cotton} (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.

the gun port.

{Gun tackle purchase} (Naut.), a tackle composed of two
single blocks and a fall. --Totten.

{Krupp gun}, a wrought steel breech-loading cannon, named
after its German inventor, Herr Krupp.

{Machine gun}, 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.

{To blow great guns} (Naut.), to blow a gale. See {Gun}, n.,
3.
[1913 Webster PJC]


Nitrocellulose \Ni`tro*cel"lu*lose`\, n. [Nitro- cellulose.]
(Chem.)
See {Gun cotton}, under {Gun}.
[1913 Webster]
