  • the first escape wheel and the first coupling wheel can be mounted without problem. one at a distance from the other, in particular from so as to house the anchor 4 in a plane intermediate to these two wheels.
  • the shank 27 must have a certain length so that the guiding of the first exhaust mobile is sufficiently precise.
  • the first exhaust mobile also has a direct mechanical connection intended to receive the energy transmitted by a motor train.
  • This direct mechanical connection comprises, for example, an exhaust pinion 26 intended to mesh with a toothed wheel of a second mobile.
  • the first escape wheel like the first coupling wheel, is fixedly mounted on the tigeron. At the very least, the first escape wheel, the first coupling wheel and the escape pinion are integral in rotation.
  • the first escape wheel, the first coupling wheel and the escape pinion can be mounted by means of splines on the shank. Furthermore, the first escape wheel and the first coupling are indexed in position relative to each other.

  • the second escape wheel comprises escape teeth 32 intended to cooperate with the vanes.
  • the second escapement wheel and the second coupling wheel are mounted coaxially on the same rod 37.
  • the structure of the second escape wheel assembly is identical to the structure of the first escape wheel assembly, unlike that the second mobile exhaust does not have a direct mechanical connection to the engine train.

  • the anchor is mounted on a tigeron 47. It is articulated around an axis 41.
  • the anchor mainly carries 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 other end of the stick, a fork 45 and a dart 46.
  • the fork is intended to cooperate with a pin 55 of the plate.
  • the dart is intended to cooperate with a small plate 54 of the plate and a notch 56 made in this small plate.
  • the plate is mounted on a tigeron 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 integral with the large rotating plate.
  • a pin 55 is planted in the large plate and is intended to cooperate with the fork 45.
  • a third impulse vane 52 cooperating with the teeth 22 of the first escape wheel, is mounted on the large plate. .
  • a fourth impulse vane 53 cooperating with the teeth 32 of the second escape wheel, is mounted on the large plate.

  • the plate is intended to be mechanically coupled to the regulating member of the timepiece.
  • the plate is fixed integral in rotation with the regulator member, in particular fixed integral in rotation with a balance of a sprung balance system.
  • the axis 58 around which the plate is articulated and / or the axis 41 around which the anchor is articulated is contained in a plane median to the axes of rotation 23, 33 of the first and second mobile exhaust.
  • the two mobile exhaust are therefore in a stop position: the second mobile exhaust being in a stop position because it is in contact with the stop pallet 43 and the first mobile exhaust being in a position of 'stop because it is linked or coupled in rotation to the second mobile exhaust.
  • the plate has just received an impulse that it has transferred to the regulating organ, in particular to the balance of the regulating organ.
  • the plate secured to the balance therefore continues its angular travel in the direction indicated by arrow 103 to travel an additional ascending arc, then in the direction indicated by arrow 104 to travel an additional descending arc until returning to the configuration of the figure 2 .
  • the pin returns to a position of cooperation with the fork of the anchor and drives the latter in clockwise rotation until it comes to the configuration of the anchor. figure 3 .
  • no exhaust tooth interferes with a stop vane.
  • the two exhaust wheels therefore rotate simultaneously in the directions represented by arrows 101 and 102.
  • This rotation of the exhaust wheels continues until the tooth of the second exhaust wheel set, referenced 32 on the figure 3 , comes to rest against the impulse paddle 53.
  • the second exhaust mobile 3 gives the plate 5 an impulse via the exhaust tooth referenced 32 and the impulse vane 53.
  • the second exhaust mobile therefore continues to rotate in the direction indicated by the arrow 102 and the first exhaust mobile therefore continues to rotate in the direction indicated by the arrow 101.
  • the anchor driven by the plate 5 via the pin 55 pivots clockwise and brings the stop pallet 42 into a position of 'interference with the tooth of the first exhaust mobile referenced 22 on the figures 3 and 4 .
  • the two exhaust wheels are therefore in a stop position: the first exhaust mobile being in a stop position because it is in contact with the stop pallet 42 and the second exhaust mobile being in a position stop because it is linked in rotation to the first exhaust mobile.
  • the plate has just received an impulse that it has transferred to the regulating organ, in particular to the balance of the regulating organ.
  • the plate secured to the balance therefore continues its angular travel in the direction indicated by arrow 104 to travel an additional ascending arc, then in the direction indicated by arrow 103 to travel an additional descending arc until returning to the configuration of the figure 4 .
  • the pin returns to a position of cooperation with the fork of the anchor and drives the latter in anti-clockwise rotation until it comes into a configuration similar to that of the anchor.
  • figure 3 this configuration differing only from that of the figure 3 by a rotation of the two exhaust wheels of ⁇ / n radians, with n the number of exhaust teeth of each exhaust mobile.
  • no exhaust tooth interferes with a stop vane.
  • the two mobiles exhaust therefore rotate simultaneously in the directions represented by arrows 101 and 102. This rotation of the exhaust wheelsets continues until a tooth of the first exhaust mobile device comes into contact with the impulse paddle 52 From this contact, the first exhaust mobile 3 gives the plate 5 an impulse via the exhaust tooth and the impulse vane 52.
  • the first exhaust mobile therefore continues to rotate in the direction. indicated by the arrow 101 and the second mobile escape therefore 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 anti-clockwise direction and brings the pallet to. stop 43 in a position of interference with a tooth of the second exhaust mobile.
  • 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.
  • the structure of the escapement according to the invention is very simple. Likewise, each of its constituent parts, in particular the anchor, is very simple. It is also noted that the structure of the escapement is symmetrical, the only elements of asymmetry being summed up in the presence of an escapement pinion on only one of the escapement wheels and an offset by an angle of ⁇ / n of the two escape wheels.
  • each of the escape wheels transmits a single impulse to the regulating member during an oscillation.
  • the first escape wheel transmits an impulse to the regulating member during the first half-wave of the oscillation and the second escape wheel transmits an impulse to the regulating member during the second half-wave of the oscillation.
  • This direct transmission of energy from an escape wheel to the chainring at each alternation improves precision.
  • the regulating organ receives impulses while it is in symmetrical positions.
  • the escapement allows automatic starting of the movement when the barrel is cocked. Indeed, we see that, in the configuration of the figure 3 corresponding to the rest position of the regulating member, none of the stop vanes is in the configuration of interference with a tooth of the escape wheels. It follows that when the barrel is armed, the escapement wheels will naturally turn and transmit to the regulating member a first impulse making it possible to initiate the movement.
  • the angle ⁇ formed between the planes of the pulse vanes 52 and 53 may for example be between 55 ° and 66 °.
  • the retraction of the escape wheel when the stop vane leaves an interference position can be 0.5 °.
  • the pivoting amplitude of the anchor (2 ⁇ ⁇ ) can be equal to 14 °.
  • the escape wheels or even other elements of the escape wheels, can be made of a material with a high density, for example of gold.
  • An exhaust according to the invention does not require lubrication.
