Machine \Ma*chine"\ (m[.a]*sh[=e]n"), n. [F., fr. L. machina
machine, engine, device, trick, Gr. mhchanh`, from mh^chos
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.
[1913 Webster]
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.
[1913 Webster]
2. Any mechanical contrivance, as the wooden horse with which
the Greeks entered Troy; a coach; a bicycle. --Dryden.
--Southey. --Thackeray.
[1913 Webster]
3. A person who acts mechanically or at the will of another.
[1913 Webster]
4. A combination of persons acting together for a common
purpose, with the agencies which they use; as, the social
machine.
[1913 Webster]
The whole machine of government ought not to bear
upon the people with a weight so heavy and
oppressive. --Landor.
[1913 Webster]
5. A political organization arranged and controlled by one or
more leaders for selfish, private or partisan ends; the
Tammany machine. [Political Cant]
[1913 Webster]
6. Supernatural agency in a poem, or a superhuman being
introduced to perform some exploit. --Addison.
