CLOCK DRIVE Russian patent published in 2020 - IPC G04B1/00 

FIELD: watches and other time measuring instruments.

SUBSTANCE: clock drive mechanism (100), comprising base (110), on which rotary lever (1) is installed, subjected to action of return torque of first energy source (12), wherein this lever (1) supports satellite (10), comprising wheel (11), second power source (22), which acts by return torque on third wheel (3) in assembly, on which wheel (11) is driven by first energy source (12), wherein base (110) supports thrust means (120) interacting with mating thrust means (123) of third wheel (3) in assembly to hold the latter in required position and capable of leaving connection under action of disengagement means (13) contained in lever (1), when lever (1) reaches end of angular forward movement, providing rotation of third wheel (3) in assembly in single direction (F) under action of second energy source (22), causing rotation in reverse direction of lever (1) to beginning of its angular movement.

EFFECT: clock drive mechanism is proposed.
