MACHINE, n. [L. machina.] An artificial work, simple or complicated, that serves to apply or regulate moving power, or to produce motion, so as to save time or force. The simple machines are the six mechanical powers, viz.; the lever, the pulley, the axis and wheel,the wedge, the screw, and the inclined plane. Complicated machines are such as combine two or more of these powers for the production of motion or force.

1. An artificial work, simple or complicated, that serves to apply or regulate moving power, or to produce motion, so as to save time or force. The simple machines are the six mechanical powers, viz. the lever, the pulley, the axis and wheel, the wedge, the screw, and the inclined plane. Complicated machines are such as combine two or more of these powers for the production of motion or force. Encyc.
2. An engine; an instrument of force. With inward arms the dire machine they load. Dryden.
3. Supernatural agency in a poem, or a superhuman being introduced into a poem to perform some exploit. Pope.

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.
   
   

   * 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, 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. To subject to the action of machinery] to effect by aid of machinery; to print with a printing machine.
3. Any mechanical contrivance, as the wooden horse with which the Greeks entered Troy; a coach; a bicycle.

4. A person who acts mechanically or at the will of another.
5. A combination of persons acting together for a common purpose, with the agencies which they use; as, the social machine.

6. A political organization arranged and controlled by one or more leaders for selfish, private or partisan ends.
