Definitions

  • the present invention relates to the exhaust regulating members comprising an escapement, a balance and a spiral spring and more particularly to a mechanical device for setting the exhaust system to a reference point so that at neutral position or equilibrium position , the center of the plate anchor is on the anchor-pendulum axis so that the functions of the escapement are symmetrical with respect to the equilibrium position.
  • the mechanical marking device is more particularly intended for regulating members comprising a balance with inertial adjustment and a spiral whose inner end is fixed rigidly to a shell of the axis of the balance while the outer end the spiral spring is fixed rigidly to a pin carried by a bolt carrier movable angularly concentrically to the axis of the balance.
  • the mobile peg carrier is pivoted to hard friction on a part of the cock or balance beam concentric to the balance shaft.
  • This setting is carried out directly manually when the watchmaker manually modifies the angular position of the peg carrier on the rooster to place the outer end of the hairspring in a position such that the shelf pin driven by the pendulum is, in the balance position of the balance, in the anchor-pendulum axis.
  • Such a setting is imprecise and difficult to achieve by a person who is not highly qualified.
  • This setting is carried out indirectly indirectly manually when the watchmaker actuates in rotation an eccentric pivoted in the cock and acting on the bolt carrier.
  • the watchmaker To train this eccentric in rotation, the watchmaker must with a tool, usually a screwdriver, press strongly on the eccentric to prevent any slipping of the tool. This pressure is reflected on the part of the cock with the pivot of the pendulum which is cantilevered and may cause damage to this bearing.
  • the mechanical device for marking the exhaust according to the invention tends to obviate the aforementioned drawbacks and is intended for a fine, mechanical and effortless adjustment, which can therefore be very precise, of the angular position of the bolt carrier on the cock of an inertial balance regulator system and this without risk of damaging the balance bearing.
  • the present invention relates to a mechanical device for setting the reference of the escapement of a regulating member comprising an inertial balance and a hairspring of fixed length.
  • the balance 1 is of the inertial type and comprises adjustable flyweights 2 which make it possible to modify the inertia of the balance 1 according to their angular position in order to finely adjust the oscillation frequency of the balance.
  • This balance 1 is integral with a balance shaft 3 pivoted in bearings of which only one carried by the cock 4 or balance bridge is shown in the drawing.
  • This balance shaft 3 carries a ferrule 5 to which the inner end of the spiral 6 is fixed.
  • the outer end of the hairspring 6 is fixed on a peg 7 fixed by means of a peg plate 8 and screw 9 on a mobile peg carrier 10.
  • This movable bolt carrier 10 is pivoted with hard friction on a boss 12 which includes the lower face of the cock concentrically to the bearing 13 of the cock 4 receiving the upper end of the balance shaft 3.
  • the movable pin holder 10 further comprises an arm 14 on which is screwed a door corrector- 15.
  • This corrector peg holder 15 moves in an opening 16 that includes the cock 4.
  • This corrector 15 has an upper portion located above the upper surface of the cock 4.
  • the free end of the arm 14 of the bolt carrier 10 rests on a rib 17 of the cock 4, rib 17 which extends in a housing that has the free end of the corrector of peg holder 15.
  • the arm 14 of the door -piton 10 is maintained in its plane during its angular oscillations due to the pivoting movement printed at the stud holder 10 concentrically to the balance shaft 3.
  • the mechanical setting device comprises a return spring 18 with a gooseneck whose heel 19 is fixed to the cock 4 to the lug. 20 with the free end 21 bears against a first side face of the stud holder 15 tending to move the latter in the direction of the heel 19 of the return spring 18.
  • the spring 18 is arranged and fixed on the upper face of the cock 4 and its free end is in contact with the upper part of the first lateral face of the corrector 15.
  • the heel 19 of the return spring 18 in gooseneck comprises a thread in which is screwed a micrometer screw 22 whose end 23 constitutes a adjustable stop against which the corrector peg holder 15 is applied by its second side face, opposite to the first, under the action of the return spring 18.
  • the micrometer screw 22 is greasy or hard friction in its tapping to prevent that shocks or vibrations may change its position once the benchmark is made.
  • other locking means of this micrometer screw 22 can be provided such as a matting of the thread, an elastic thread brake or a forced thread (diameter or not slightly different thread and screw), etc.
  • the elastic return action exerted on the corrector 15 of the bolt carrier 10 is made by a different spring or a different elastic action than that of a spring with a gooseneck for example a leaf spring or a coil spring.
  • the heel 19 serves only to screw the screw 22.
  • the mechanical setting device may be envisaged, all of them in common a movable pin holder pivoted on the cock concentrically to the balance shaft and having a substantially radial arm subjected to an elastic action of recall tending to support against an adjustable stop carried by the rooster.
  • the micrometric screw 22, 23 forming the adjustable stop against which the corrector 15 abuts is replaced by a snail cam 24 pivoting about an axis 25 perpendicular to the plane of the cock 4 and whose outer periphery serves as a stop to said corrector.
  • This snail cam 24 is pivoted on the cock 4 and a screw 25 makes it possible to fix the angular position of this cam 24 with respect to the cock 4.
  • the snail cam 24 is integral with a disc 26 provided with pins 27 making it possible to appreciate the position of the cam 24 with respect to the cock 4.
  • the stud holder corrector 15 comprises a probe-shaped end 15a applied against the outer periphery of the snail cam 24 by a spring 18 fixed on cock 4 by his heel 19.
  • the setting of the benchmark is also easy and accurate and can be done by a skilled worker and not necessarily by a trimmer.
  • Another advantage of the mechanical device for setting the exhaust system according to the invention lies in the fact that the bolt carrier is pivoted under the cock, so the rocker and balance side of the cock, which facilitates the fixing of the end outer of the spiral on the peak.
  • the upper face of the cock which is visible once the watch movement is finished, has an original decorative appearance with the opening of the cock, the corrector, its return spring and the adjustable stop, the micrometer screw or snail cam for example, which is still popular for high-end and collectible watches.
