2. Maintaining power - Wikipedia

   en.wikipedia.org/wiki/Maintaining_power

   Huygens' maintaining power in use. The weight drive used by Christiaan Huygens in his early clocks acts as a maintaining power. In this layout, the weight which drives the clock is carried on a pulley and the cord (or chain) supporting the weight is wrapped around the main driving wheel on one side and the rewinding wheel on the other.

3. Mainspring - Wikipedia

   en.wikipedia.org/wiki/Mainspring

   After winding, the arbor is stationary and the pull of the mainspring turns the barrel, which has a ring of gear teeth around it. This meshes with one of the clock's gears, usually the center wheel pinion and drives the wheel train. The barrel usually rotates once every 8 hours, so the common 40-hour spring requires 5 turns to unwind completely.

6. Clockwork - Wikipedia

   en.wikipedia.org/wiki/Clockwork

   [1] [2] [3] A clockwork mechanism is often powered by a clockwork motor [4] consisting of a mainspring, a spiral torsion spring of metal ribbon. Energy is stored in the mainspring manually by winding it up, turning a key attached to a ratchet which twists the mainspring tighter. Then the force of the mainspring turns the clockwork gears, until ...

7. Coil winding technology - Wikipedia

   en.wikipedia.org/wiki/Coil_winding_technology

   Orthocyclic winding Orthocyclic wound coil Orthocyclic winding of a round coil Orthocyclic winding of a rectangular motor coil. This type of winding structure creates an optimal fill factor (90.7%) for round wires. The windings of the upper layer need to be placed into the grooves provided by the lower layer.

9. Atmos clock - Wikipedia

   en.wikipedia.org/wiki/Atmos_clock

   The first Atmos clock was designed by Jean-Léon Reutter, an engineer in Neuchâtel, Switzerland, in 1928. [5] [6] [7] This noncommercial prototype, which predated the Atmos name but is now known unofficially as Atmos 0, was driven by a mercury-in-glass expansion device. The mechanism operated on temperature changes alone. [8] [5] [6]
