(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
. 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

, 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

machine, engine, device, trick, Gr. ?, from ? means,
expedient. Cf. Mechanic
1. In general, any combination of bodies so connected that
their relative motions are constrained, and by means of
which force and motion may be transmitted and modified, as
a screw and its nut, or a lever arranged to turn about a
fulcrum or a pulley about its pivot, etc.; especially, a
construction, more or less complex, consisting of a
combination of moving parts, or simple mechanical
elements, as wheels, levers, cams, etc., with their
supports and connecting framework, calculated to
constitute a prime mover, or to receive force and motion
from a prime mover or from another machine, and transmit,
modify, and apply them to the production of some desired
mechanical effect or work, as weaving by a loom, or the
excitation of electricity by an electrical machine.
Note: The term machine is most commonly applied to such
pieces of mechanism as are used in the industrial arts,
for mechanically shaping, dressing, and combining
materials for various purposes, as in the manufacture
of cloth, etc. Where the effect is chemical, or other
than mechanical, the contrivance is usually denominated
an apparatus or device, not a machine; as, a bleaching
apparatus. Many large, powerful, or specially important
pieces of mechanism are called engines; as, a steam
engine, fire engine, graduating engine, etc. Although
there is no well-settled distinction between the terms
engine and machine among practical men, there is a
tendency to restrict the application of the former to
contrivances in which the operating part is not
distinct from the motor.
2. Any mechanical contrivance, as the wooden horse with which
the Greeks entered Troy; a coach; a bicycle. --Dryden.
3. A person who acts mechanically or at the will of another.

metal, in distinction from one which is designed

, a workshop where machines are made, or where
metal is shaped by cutting, filing, turning, etc.
, a machine for cutting or shaping wood, metal,
etc., by means of a tool; especially, a machine, as a
lathe, planer, drilling machine, etc., designed for a more
or less general use in a machine shop, in distinction from
a machine for producing a special article as in
, silken thread especially adapted for use in
a sewing machine.
, work done by a machine, in contradistinction
to that done by hand labor.
