Natural escapement
First Claim
1. An escapement mechanism for a timepiece comprising:
- a stop member between a resonator and a first escape wheel set and a second escape wheel set, each subjected to a torque;
wherein each escape wheel set includes at least one magnetized or ferromagnetic, or respectively, electrically charged or electrostatically conductive track with a period of travel over which the magnetic, or respectively, electrostatic characteristics thereof are repeated, the stop member including at least one magnetized or ferromagnetic, or respectively, electrically charged or electrostatically conductive pole shoe, the pole shoe being movable in a transverse direction relative to a direction of travel of at least one element of a surface of the track, and at least the pole shoe or the track creating a magnetic or electrostatic field in an air-gap between the at least one pole shoe and the at least one surface,wherein the pole shoe is confronted with a magnetic or electrostatic field barrier on the track just before each transverse motion of the stop member actuated by periodic action of the resonator,wherein the first escape wheel set subjected to a first torque and the second escape wheel set subjected to a second torque are each arranged to be configured to cooperate alternately with the stop member, andwherein the first escape wheel set and the second escape wheel set pivot about distinct axes and are connected to each other by a direct kinematic connection.

Abstract
An escapement mechanism including a stop member between a resonator and two escape wheel sets each subjected to a torque, and each including a magnetized or ferromagnetic track over a period. The stop member includes at least one magnetized or ferromagnetic pole shoe, transversely movable with respect to travel of a surface of the track. The pole shoe or the track creates a magnetic field between the pole shoe and the surface, and the pole shoe is confronted by a magnetic field barrier on the track just before each transverse motion of the stop member actuated by the period action of the resonator. The escape wheel sets are each arranged to cooperate alternately with the stop member, and are connected to each other by a direct kinematic connection.
