  • the anchor is mounted on a beam 47. It is articulated about an axis 41.
  • the anchor carries mainly at one end of a rod 44, on a first arm, a first stop pallet 42 cooperating with the teeth 22 of the first escape wheel and, on a second arm, a second stop pallet 43 cooperating with the teeth 32 of the second escape wheel.
  • the anchor also includes, at a another end of the rod, a fork 45 and a dart 46.
  • the fork is intended to cooperate with an ankle 55 of the plate.
  • the dart is intended to cooperate with a small plate 54 of the tray and a notch 56 made in this small tray.
  • the plate is mounted on a rod 57. It is articulated around an axis 58.
  • the plate 5 is of the double plate type. It therefore comprises a large plate 51 and a small plate 54.
  • the small plate is secured to the large plate in rotation.
  • a pin 55 is planted in the large plate and is intended to cooperate with the fork 45.
  • a third pulse pallet 52 cooperating with the teeth 22 of the first escape wheel, is mounted on the large plate .
  • a fourth impulse pallet 53 cooperating with the teeth 32 of the second escape wheel, is mounted on the large plate.
  • the small plate 54 and its notch 56 cooperate with the dart 46 of the anchor.
  • the tray is intended to be mechanically coupled to the regulating member of the timepiece. For example, the plate is fastened in rotation with the regulating member, in particular fixed to rotate with a balance of a balance spring system.
  • the axis 58 around which the plate is hinged and / or the axis 41 around which the anchor is hinged is contained in a median plane to the axes of rotation 23, 33 of the first and second mobile exhaust.
  • the first escapement mobile 2 has just given the plate 5 a pulse via the exhaust tooth referenced 22 on the figure 2 and the impulse pallet 52.
  • the first mobile exhaust has therefore rotated in the direction indicated by the arrow 101 and the second mobile exhaust has just turned in the direction indicated by the arrow 102.
  • the anchor driven by the plate 5 via the pin 55 has just pivoted in the anticlockwise direction and bring the stop pallet 43 into an interference position with the exhaust tooth of the second mobile exhaust referenced 32 on the figure 2 .
  • the two exhaust movers are therefore in a stopping position: the second exhaust movable being in a stop position because it is in contact with the stopping pallet 43 and the first escapement mobile being in a position d stop because it is linked or coupled in rotation to the second mobile exhaust.
  • the plate has just received an impulse which it has transferred to the regulating member, in particular to the balance of the regulating member.
  • the platform secured to the balance therefore continues its angular travel in the direction indicated by the arrow 103 to travel an additional upward arc, then in the direction indicated by the arrow 104 to travel an additional arc down to return to the configuration of the figure 2 .
  • the peg returns to a position of cooperation with the fork of the anchor and drives the latter in rotation clockwise until coming into the configuration of the figure 3 .
  • no exhaust teeth interferes with a stop pallet.
  • the two escape wheels thus rotate simultaneously in the directions represented by the arrows 101 and 102.
  • This rotation of the escape mobiles continues until the tooth of the second mobile exhaust, referenced 32 on the figure 3 , comes to bear against the impulse pallet 53.
  • the second mobile exhaust 3 gives the plate 5 a pulse through the exhaust tooth referenced 32 and the pulse pallet 53.
  • the second mobile exhaust continues to rotate in the direction indicated by the arrow 102 and the first escapement mobile continues to rotate in the direction indicated by the arrow 101.
  • the anchor driven by the plate 5 via the pin 55 rotates clockwise and brings the stop pallet 42 into a position d interference with the tooth of the first exhaust mobile referenced 22 on the Figures 3 and 4 .
  • the two exhaust mounts are thus in a stopping position: the first mover is in a stop position because it is in contact with the stopping pallet 42 and the second mover is in a position stop because it is connected in rotation to the first mobile exhaust.
  • the plate has just received an impulse which it has transferred to the regulating member, in particular to the balance of the regulating member.
  • the plate secured to the balance therefore continues its angular stroke in the direction indicated by the arrow 104 to travel an additional upward arc, then in the direction indicated by the arrow 103 to travel an additional arc down to return to the configuration of the figure 4 .
  • the ankle returns to a position of cooperation with the fork of the anchor and drives the latter in rotation in the counterclockwise direction until coming in a configuration similar to that of the figure 3 , this configuration differing only from that of the figure 3 by a rotation of the two exhaust mobiles ⁇ / n radians, with n the number of exhaust teeth of each mobile escape.
  • no exhaust teeth interferes with a stop pallet. Both mobiles exhaust thus rotate simultaneously in the directions represented by the arrows 101 and 102. This rotation of the escape mobile continues until a tooth of the first movable exhaust comes into contact against the pulse pallet 52 From this contact, the first escapement mobile 3 gives the plate 5 a pulse via the exhaust tooth and the pulse pallet 52.
  • the first exhaust mobile therefore continues to rotate in the direction indicated by the arrow 101 and the second mobile exhaust continues to rotate in the direction indicated by the arrow 102.
  • the anchor driven by the plate 5 via the pin 55 pivots in the counterclockwise direction and brings the pallet stop 43 in an interference position with a tooth of the second mobile exhaust. We find our again in the configuration of the figure 2 .
  • the escapement is of the free type, that is to say that the balance can travel an additional arc after the pin of the plate has left the fork of the anchor.
  • each component, including the anchor, is very simple.
  • the structure of the escapement is symmetrical, the only elements of dissymmetry being summed up in the presence of an exhaust pinion on only one of the exhaust mobiles and at an offset of an angle of ⁇ / n two exhaust wheels.
  • each of the escape wheels transmits a single pulse to the regulating member during an oscillation.
  • the first escape wheel transmits a pulse to the regulating member during the first oscillation cycle and the second escape wheel transmits a pulse to the regulating member during the second oscillation cycle.
  • This direct transmission of energy from an escape wheel to the plate at each alternation makes it possible to improve the accuracy.
  • the regulating organ receives pulses while it is in symmetrical positions.
  • the angle ⁇ formed between the planes of the impulse pallets 52 and 53 may for example be between 55 ° and 66 °.
  • the retreat of the escape wheel when the stopping pallet leaves an interference position may be 0.5 °.
  • the pivoting amplitude of the anchor (2 ⁇ ⁇ ) can be 14 °.
  • the escape wheels or even other elements of the escape mobiles, can be made of a high density material, for example gold.
  • An exhaust according to the invention does not require lubrication.
