Machine, n.
Etymology: [F., fr. L. machina machine, engine, device, trick, Gr. 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, 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. Southey. Thackeray.
3. A person who acts mechanically or at will of another.

Shades of meaning
Fernald has no entry of its own for machine; he lists it under tool.
Where he writes about it:
A machine in the most general sense is any mechanical instrument for the conversion of motion; in this sense a lever is a machine; but in more commonly accepted usage a machine is distinguished from a tool by its complexity, and by the combination and coordination of powers and movements for the production of a result. — from tool
A chisel by itself is a tool; when it is set so as to be operated by a crank and pitman, the entire mechanism is called a machine; as, a mortising-machine. — from tool
An apparatus may be a machine, but the word is commonly used for a collection of distinct articles to be used in connection or combination for a certain purpose--a mechanical equipment; as, the apparatus of a gymnasium; especially, for a collection of appliances for some scientific purpose; as, a chemical or surgical apparatus; an apparatus may include many tools, instruments, or implements. — from tool
Implement is for the most part and utensil is altogether restricted to the literal sense; instrument, machine, and tool have figurative use, instrument being used largely in a good, tool always in a bad sense; machine inclines to the unfavorable sense, as implying that human agents are made mechanically subservient to some controlling will; as, an instrument of Providence; the tool of a tyrant; a political machine. — from tool
