Definitions

  • the present invention relates to a natural escapement for a clock movement also known by its name tangential impulse escapement.
  • the present invention relates more particularly to a natural escapement protected against the damage that may be caused by premature triggering of the escapement pulse.
  • Breguet's natural escapement has the particular advantage of being a free escapement insofar as the balance is only disturbed by the operation of the escapement over a small fraction of its oscillation. Breguet's natural escapement also has the advantage of giving each alternation a direct and tangential impulse to the balance wheel. In other words, the energy is transferred directly from the escape wheel to the balance wheel, without passing through an anchor. Furthermore, the transmission of energy takes place only tangentially, so that the friction generated by the operation of this escapement is limited.
  • the natural escapement is arranged to be driven by a wheel set of the gear train of the clockwork movement, for example the second wheel set 2, which meshes with a pinion 4 mounted fixed on an axis 6 of a first escape wheel set which, in the example shown in figure 1 , consists of a first escapement wheel 8.
  • This first escapement wheel 8 in turn meshes via a toothing 10 with a second escapement mobile which, in the example shown in the drawing, consists of a second escape wheel 12 which pivots around an axis 14.
  • the second mobile 2 which supplies the natural escapement 1 with the energy necessary for its operation rotates counterclockwise. .
  • the second mobile 2 therefore tends to rotate the pinion 4 and the first escapement wheel 8 on the axis 6 of which the pinion 4 is fixed in the clockwise direction, and the second escapement wheel 12 in the clockwise direction. counterclockwise.
  • the clockwise pivoting of the anchor 30 has the effect of releasing the second escapement wheel 12 from its grip with the output pallet 34, which allows the second mobile 2 to drive, via the first escapement wheel escapement 8, the second escapement wheel 12 counterclockwise (see Fig. 2C ).
