  • the invention relates to an improved Swiss lever escapement mechanism, arranged to cooperate with a balance of a regulating member, said balance having a large plate provided with a plateau pin, and a small plate provided with a notch.
  • the invention further relates to a method of manufacturing or processing a Swiss anchor or a Swiss lever escapement.
  • the invention also relates to a timepiece comprising at least one improved Swiss lever escapement according to the invention.
  • the invention relates to the field of watchmaking, and more specifically of portable watchmaking.

  • the Swiss lever escapement is the most widespread because it is the most interesting from the point of view of the movement's operational safety, especially for portable watchmaking.
  • Each pallet is terminated by a pulse surface, generally an inclined plane, which receives the impulse imparted by a tooth of the escape wheel.
  • a draw is called a safety arrangement for holding the fork rod against a limit stop, while the rocker performs an additional oscillation arc, ie an arc traversed outside the functions of the beam. exhaust (before release or after the impulse according to the pallet concerned).
  • the surface of the pallet on which the tooth of the escape wheel rests while the pendulum traverses this additional arc is called rest. Pulling makes it possible to press the rod against the limit stop during the execution of the additional angle, and makes it possible to bring it back quickly during an impact.
  • the draft angle is defined by, on the one hand, this plane of rest, and on the other hand by a perpendicular raised on a radius of the anchor, at the point of contact between the pallet and the tooth of the wheel of exhaust.
  • This angle is designed to resist release, and has been introduced to overcome a defect called overturning, in case of accidental shock, in which the fork rod moves away from the limit stops during the additional oscillation, and the ankle of The balance plate then comes up against the back of the horns of the fork.
  • the exhaust is an energy dispensing member, which periodically transmits to the regulator member a portion of the energy that it receives itself from the engine means, typically barrel or the like. Friction is responsible for energy loss, which affects the performance of the exhaust, since it is estimated that the exhaust transmits only about 30% of the driving force it receives.
