Definitions

  • the object of the invention is a watch movement comprising a date indicator provided with thirty-one teeth and a moon phase indicator secured to a wheel with fifty-nine teeth and an intermediate mobile, driven in rotation by the movement of the watch at the rate of one revolution in twenty-four hours and which advances each of these indicators by one step each revolution.
  • An old Swiss patent (CH-A-13243) describes a mechanism comprising an intermediate wheel driven in rotation by the barrel wheel carrying the hour hand at the rate of one revolution in twenty-four hours.
  • This intermediate wheel is provided with two pins which, at each turn, advance by one step, respectively an eccentric wheel with thirty-one teeth, to indicate the successive dates, and a wheel with fifty-nine teeth, also eccentric, for indicate the corresponding moon phases.
  • a Vacheron & Constantin caliber (presented in the book “Modern watches-calendar” by B. Humbert, published in 1953 by the Editions du “Journal suisse horlogerie", pages 96 and 97, Fig. 156) is equipped with a similar mechanism, in which the intermediate wheel is however driven in rotation, not by the hour wheel itself, but by a pinion fixed thereto. At each revolution, this intermediate wheel advances by one step, on the one hand, the wheel with thirty-one teeth, secured to the date indicator, using a pin, and, on the other hand , the wheel with fifty-nine teeth, secured to the moon phase indicator, using a finger. In this caliber, the wheel with thirty-one teeth is mounted in the center of the movement, which allows it to set an indicator of the same diameter as the movement.
  • the invention aims to create a movement of the type indicated at the start, which can be of smaller caliber than those of known movements, the operation of which is nevertheless assured, in particular without reducing the tolerances below the usual limits.
  • Those defined by claim 3 specify the drive members of these indicators, preferably used, which makes the manufacture of the intermediate mobile particularly easy.
  • Claim 4 defines the most advantageous direction of movement of this intermediate mobile.
  • claim 5 allow mounting of the indicators mentioned on the watch movement as simple as effective and advantageous.
  • FIG. 1 a movement with a plate 10, a dial 12, hands 14 and a time-setting crown 16.
  • the dial 12 has windows 18 and 20 through which date indicators 22 appear respectively and moon phases 24.
  • the dial and the moon phase indicator have been removed, so that it is possible to see the mechanism for driving the indicators.
  • an hour wheel 26 which carries the hour hand, as well as a six-tooth wheel 28.
  • This wheel 28 meshes with an intermediate mobile 30 schematically shown and swivels on a stud 32 fixed to the plate 10.
  • the date indicator 22 is integral with a toothing 34 comprising thirty-one teeth which together form a ring 35.
  • the ring 35 is pivotally mounted on the plate 10, at its periphery and coaxially with the hands.
  • Indi moon phase generator 24 is fixed to a wheel 36 comprising fifty-nine teeth and pivotally mounted on the barrel of the hour wheel 26.
  • the toothing 34 and the wheel 36 are driven by the mobile 30, by means which will be specified with reference to FIGS. 3 and 4.
  • the indicators 22 and 24 are positioned by jumper springs 37 and 38 which cooperate respectively with the toothing 34 and the teeth of the wheel 36.
  • the mobile 30 has twelve teeth and therefore performs one revolution in twenty-four hours.
  • This mobile 30 has a cutout, which defines two flat cam surfaces 39, 40 and an elastic arm 42.
  • the arm 42 maintains, in all the angular positions of the mobile 30, the cam surfaces 39, 40 bearing against the cylindrical stud fixed 32, which has a flat 44.
  • This mobile 30 has a first drive member, which is constituted by a tooth 46, longer than the others and of particular profile.
  • the tooth 46 grasps a tooth of the toothing 34, of which only a part is shown in FIG. 3.
  • the tooth 46 advances the toothing 34 in a step as described below.
  • the wheel 30 also carries a pin 48, which constitutes a second drive member. At each revolution of the wheel 30, the pin 48 grasps a tooth of the wheel with fifty-nine teeth 36 and advances it by one step. As the synodic revolution of the moon has a duration of approximately twenty-nine and a half days, that is to say the duration between two successive conjunctions with the sun, the wheel 36 performs one revolution approximately in two lunar months.
  • the tip of the tooth 46 would pass through the arc of a circle 50.
  • the cam surface 39 began to pivot around the edge 52 of the pad 32, until this cam surface 39 is pressed against the flat 44, then it continues its movement by pivoting around the edge 54 of the pad 32.
  • the tip of the tooth 46 thus traverses the curve 56.
  • the tooth 46 plunges more deeply into the teeth of the ring 35 than if the intermediate mobile 30 was fixed on a pivoted axis in fixed bearings, as was the case in known movements. In this way, the drive of the ring 35 is ensured, even if the dimensions of the movement are reduced.
  • tooth 46 came into contact with tooth 58 of ring 35, which then occupied the position of tooth 60, and brought this tooth 58 with it, until the edge of the jumper 37 has passed beyond a tooth of the ring 35.
  • the jumper 37 which abruptly completed the advance of the ring 35 until the moment when it is engaged in the next dent of the toothing of the ring 35.
  • the position shown in the drawing is that in which the pin 48 has precisely come into contact with the tooth 64 of the wheel 36.
  • the mobile 30 will drive the tooth 64, using the pin 48, fairly far so that the jumper 38 cooperating with the wheel 36 passes into the next inter-tooth, abruptly completing the advance of this wheel 36.
  • the pin 48 By actuating the time-setting crown so as to rotate the hands counterclockwise, the pin 48 comes into contact with the tooth of the wheel 36, which occupies the position of the tooth 64. It therefore drives the wheel 36 backwards, but not far enough for the corresponding jumper to engage in the previous inter-tooth, because the pin 48 traverses the arc 62 in the opposite direction, which moves it away from the wheel 36 and does it quickly come out of the teeth of this wheel.
  • This arrangement makes it possible to update the moon phase indicator simply by rotating the hands of the watch successively back and forth so as to pass the pin 48 first behind the tooth which occupies the position of the tooth 64 without ultimately changing the position of this tooth, and then driving this tooth to advance the wheel 36 by one step.
  • the updating of the ring 35 can be carried out in a similar manner.
  • the movement of the watch will however be equipped with a known mechanism, which makes it possible to drive the ring 35 rapidly around the movement, by actuating in rotation the time-setting crown previously drawn in the middle axial position.
