Definitions

  • the present invention relates to a fine adjustment device for a balance spring consisting of a particular arrangement of the racket to make the adjustment isochronism easier and more reliable in the long term
  • the invention relates also a fine adjustment process, i.e. a succession of manipulations from the setting to the benchmark to the final adjustment, the initial and final manipulations being carried out by means of a single fine adjustment device thanks to said particular arrangement.
  • a racket is composed of a set of parts mounted on the rooster, namely a piton to fix the end of the outer curve of the hairspring, and an adjusted racket with a greasy friction on the cockerel comprising a extension beyond the cock for the pins and / or the racket key and opposite tail of racket on which a screw generally acts, against the restoring force a spring, to rotate the racket by small angles and thus modify the active hairspring length.
  • the invention therefore aims to overcome the drawbacks of this prior art by providing a device much easier to handle thanks to an arrangement particular clamping / locking devices for adjusting the alignment and walking by means of a single fine adjustment device. This arrangement allows also to save on a mobile pad holder for adjusting the benchmark.
  • the invention relates to a fine adjustment device for a sprung balance.
  • the pendulum which conventionally includes balancing screws screwed in his arms, has its axis pivoted between a plate and a rooster including the cockerel allows the fitting with a bold adjustment of a swivel racket for example by example by means of an adjustment screw pressing the racket tail against the return force of a spring.
  • the hairspring turned by known means on the axis of balance can be set, adjusted for isochronism and have its outside curve fixed thanks to the fine adjustment screw and specific tightening / blocking at the level of the cock and the racket whose characteristics are explained below.
  • the rooster has a first ear extended by a bent stirrup, the feet of which extend to the outer curve of the hairspring and in which is articulated a first clamping device formed of a L-shaped tilting element whose small arm is maneuvered by a screw flange screwed into said ear to rotate the large arm and form with the inner surface of the feet of the stirrup pliers for the end of the balance spring.
  • Racket comprises, on an extension opposite to the tail of the racket, a second device clamp having the same design as the first, namely a stirrup in which a tilting L-shaped element is articulated whose flanged screw allows by screwing form a clamp to fix a chosen location on the curve outside the hairspring so to define the useful length.
  • the rooster finally has a second ear in which is screwed a third screw through an oblong opening of a tongue annular extending on one side the extension of the racket, said screw for block the racket in a position previously determined by the screwing / unscrewing the fine adjustment screw.
  • the three clamping / locking screws all have their axis parallel to the balance axis and are all accessible from the same side of the device, which facilitates adjustment operations.
  • This construction also has the advantage of being able to exercise on the curve outside the hairspring a defined clamping force, substantially perpendicular to the loop, and not causing its deformation in giving to the facing surfaces clamps formed by a stirrup and an element tilting in L the same curvature as that of the curve outside the hairspring.
  • Figures 1 and 2 show in perspective, respectively for above and in view from below, a balance-spring according to a first mode of embodiment of the invention, the assembly to be fixed on a plate with a movement watchmaking mechanics (not shown).
  • the pendulum 1 has two arms 1a, 1b into which are balanced screws 2a, 2b, its axis 3 being pivoted between a plate (not shown) and a rooster 10.
  • the pendulum 1 has a small plate 6a, a large plate 6b with a dowel pin 6c, and that a ferrule 5 makes it possible to fix the curve to the center of a hairspring 4 on the axis 3 of the pendulum 1.
  • the rooster 10 supports a racket 20, mounted with greasy friction on the cockerel 10a and the tail 20a allows to change the orientation thanks to a fine adjustment screw 7 pressing on said racket tail 20a against the return force of a gooseneck spring 8, one end of which, fixed in the cock 10 by means of two screws 8a, is crossed by said fine adjustment screw 7.
  • the rooster 10 has a first ear 11 provided with a first device for clamp forming clamp.
  • This device consists of a bent bracket 12 coming from material with the first ear 11 and whose feet 12a, 12b extend to hairspring 4, and in which an L-shaped tilting element 13 is articulated maneuverable by a clamping screw 19 with flange to form a clamp used to immobilize the end of the curve outside 4a of the hairspring 4.
  • the racket 20 comprises a second clamping device forming gripper constituted, opposite the racket tail 20a, by an extension 21 extended by a bent stirrup 22 in which is articulated a tilting element 23 in L used to pinch a portion of the curve outside 4a and thus define the useful length of hairspring 4 by acting on a second clamping screw 29 with flange.
  • the extension 21 further comprises, on one of its sides, an annular tongue 31 extending over a second ear 30 of the rooster 10.
  • the tongue 31 comprises an oblong opening 32 into which is screwed a screw 9 making it possible to block the racket 20 in a determined position after adjusting its orientation at using the fine adjustment screw 7.
  • the three screws 9, 19 and 29 and the two balancing screws 2a, 2b are all accessible from the same side, according to a direction parallel to the pendulum axis.
  • the clamps used to fix the curve outside 4a of the hairspring 4 are described with reference also to the partial bottom view of FIG. 3 and to the 4A showing in section, along a line passing through the axis of the pendulum, the clamp formed at the cock 10 by the rocking element 13, said clamp being in open position.
  • the tilting element 13 in L has a small arm 14, a large arm 15 and a hinge 13a constituted, for example, by two tenons engaged in corresponding openings of the stirrup 12 of the cock 10.
  • the small arm 14 has a notch 14a delimited by an upper lip 16 and a lower lip 18.
  • the upper lip 16 has an inclined plane 16a directed towards the inside of the notch 14a, said inclined plane 16a coming to cooperate with a inclined plane 16b of the clamping screw 19 for pivoting by unscrewing the element tilting 13 by opening the clamp.
  • the lower lip 18 is longer and extends under the collar of the clamping screw 19, so that by screwing the clamp is closed, as shown in Figure 4B.
  • the large arm 15 has at its base a shoe 17, the ends of which extend on each side opposite the inner surface of the feet 12a, 12b of the stirrup 12.
  • the shoe 17 and the feet 12a, 12b have the same curvature as the curve at the outside 4a of the hairspring 4 so that the tightening of the clamp does not cause any deformation of the strip.
  • the tilting element 23 operated by the clamping screw 29 with flange has a small arm 24 with a notch 24a delimited by an upper lip 26 with inclined plane 26a cooperating with an inclined plane 26b of the flange of the screw 29, a lower lip 28, and a large arm 25 terminated at its base by a shoe 27 opposite the feet 22a, 22b of the stirrup 22.
  • the running adjustment is carried out by means of the balancing screws 2a, 2b which allow to modify the moment of inertia of the pendulum.
  • Racket 20 has the simplified form of a ring open no longer having a racket tail and therefore not the regulating device which was constituted by the screw 7 and the gooseneck spring 8. It will be observed that such simplification would also be applicable to the first embodiment.
  • Racket 20 has an annular tongue 31 provided with an oblong opening 32 in which is engaged a screw 9 intended to be screwed into an ear 30 of the cock 10 to immobilize the racket 10 in a given position as we can see on Figure 9.
  • the racket 20 also has an extension 21 on which is mounted a clamping device no longer comprising a tilting element, but acting at the like a vice with two jaws 33, 35.
  • a fixed jaw 35 in the form of L has a small arm 34 fixed to the extension 21 by driving or riveting two studs 34a, 34b, and a large arm 36 crossed by a conical screw 39 allowing to operate a movable jaw 33 having a guide notch 33a on the small arm 34.
  • a second clamping device forming a vice 45 is mounted on a plate 47 fixed on the rooster 10 by means of a screw 48a and a tenon 48b. So we find, as previously a fixed jaw 45, and a movable jaw 43 assembled by a conical head screw 49, to allow easy adjustment of the balance spring.
