Mainspring

mainspring barrelsspringspring motor
A clockwork mechanism is often powered by a clockwork motor consisting of a mainspring, a spiral torsion spring of metal ribbon. Often power for the device is stored within it, via a winding device that applies mechanical stress to an energy-storage mechanism such as a mainspring, thus involving some form of escapement; in other cases, hand power may be utilized.
A mainspring is a spiral torsion spring of metal ribbon—commonly spring steel—used as a power source in mechanical watches, some clocks, and other clockwork mechanisms.

Movement (clockwork)

Clockwork refers to the inner workings of either mechanical machines called clocks (where it is also called the movement) or other mechanisms that work similarly, using a complex series of gears.
The term originated with mechanical timepieces, whose clockwork movements are made of many moving parts.

Antikythera mechanism

Antikythera Mechanism Research ProjectOrrery
The earliest known example of a clockwork mechanism is the Antikythera mechanism, a first-century BC geared analogue computer, somewhat astrolabe-like, for calculating astronomical positions and eclipses, recovered from a Greek shipwreck.
It is a complex clockwork mechanism composed of at least 30 meshing bronze gears.

Escapement

Often power for the device is stored within it, via a winding device that applies mechanical stress to an energy-storage mechanism such as a mainspring, thus involving some form of escapement; in other cases, hand power may be utilized.
Historically, a liquid-driven escapement was used for a washstand design in ancient Greece and the Hellenistic world, particularly Ptolemaic Egypt, while liquid-driven escapements were applied to clockworks beginning in Tang dynasty China and culminating during the Song dynasty.

Friedrich von Knauss

Friedrich von Knaus(s) (February 7 or April 7, 1724 - August 14, 1789), was a German watchmaker and inventor who built clockwork mechanisms which could, in a simple way, play musical instruments, write short phrases, or conduct other individual, specialized tasks.
