Definitions

  • the present invention relates to a date-watch, having a winding stem which may be given three distinct axial positions, namely a first position, or innermost position, permitting winding of the watch, a second position, or intermediary position, permitting the correction of the date by rotating the winding stem, and a third position, or outermost position, permitting setting the hands of the watch.
  • This date-watch comprises a clutch-pinion actuated by a yoke which is itself operated by a setting lever one end of which fits into a groove of the winding stem.
  • the date-watch referred to is broadly characterized in that it comprises in addition a lever, disposed in the same plane as the said yoke and controlled by the latter, the said lever carrying at its free end a date corrector consisting of a star-wheel and a toothed wheel rigidly connected with each other and rotatably mounted on the said lever, the whole being arranged in such a way that when the winding stem is in its first position, the clutch-pinion cannot drive the said corrector and that when the winding stem is in its second position, the clutch-pinion can drive the corrector which in turn actuates the date-disc, whereas when the winding stem is in its third position, the clutch-pinion may drive the corrector which is no longer in mesh with the teeth of the date-disc, as well as a setting wheel which is now engaged by the wheel of the corrector.
  • FIG. 1 is a plan view of this embodiment, the winding stem being in its first position.
  • FIGS. 2 and 3 are views similar to FIG. 1, the winding stem being in its second and third positions, respectively.
  • the winding stem 1 is provided with a groove 2 into which fits a pin 3 of a setting lever 4 which is rotatably mounted on a stud 5.
  • a pin 6 fixed to the setting lever 4 cooperates with the one or the other of the notches 7 to 9 of the setting lever spring 10.
  • On a square portion of the winding stem 1 is slidably arranged a clutch-pinion 11 having, on the one hand, a Breguet or saw toothing capable of driving the winding pinion 12 and, on the other hand, a contrate toothing 13 adapted to cooperate with a date corrector described later on.
  • into the groove 14 of the clutch-pinion l1 fits the free end of a yoke 15, rotatably mounted on a stud (not shown) secured to the pillar plate and subjected to the action of a return spring 16.
  • a lever 17, pivoting at the same place as the yoke 15, is arranged in the same plane as the yoke 15 and is controlled by the'latter.
  • the lever 17 is subjected to the action of a return spring 18 and its rotation in the clockwise direction is limited by a stop 19.
  • a date corrector consisting of a star-wheel 20 and a toothed wheel 21 which are rigidly connected with each other.
  • a portion of the date-disc 22 bearing on its upper face the numerals 1 to 31, adapted to successively appear through a window of the dial.
  • the minute wheel 23, rigidly fixed to the minute wheel pinion 24, is also disposed in the vicinity of the corrector 20, 21.
  • the date-disc 22 is subjected to the action of a jumperspring (not shown), which ensures a stable position of the disc 22
  • the date-watch as shown and described operates as follows:
  • the yoke 15 and the lever 17 being disposed at the same level, the described device takes little space in a vertical direction.
  • a date-watch having a winding stem which may be given three distinct axial positions, namely a first position, or innermost position, permitting winding of the watch, a second position, or intermediary position, permitting the correction of a date-disc by rotating the winding stem, and a third position, or outermost position, permitting setting the hands of the watch,
  • a clutch-pinion actuated by a yoke which is itself operated by a setting lever one end of which fits into a groove of the winding stem, characterized in that it comprises in addition a lever, disposed in the same plane as the said yoke and controlled by the latter, the said lever carrying at its free end a date correcting star-wheel and a time correcting wheel rigidly connected coaxially with each other and rotatably mounted on the said lever, the whole being arranged in such a way that when the winding stem is in its first position, the clutch-pinion cannot drive the said date correcting star-wheel and that when the winding stem is in its second position, the clutch-pinion can
  • a date-watch according to claim 1 wherein the said yoke and the said lever are each subjected to the action of a return spring.
