Definitions

  • ABSTRACT A calendar timepiece provided with a control mechanism comprising a stem arranged in such a way as to be able to occupy at least two different axial positions, the mechanism comprising, a movable member acting as a selector and which is controlled, at least indirectly, by the stem, the selector being arranged in such a way as to be able to occupy one or the other of two positions, according to the direction in which the stem is rotated, when it occupies one of its two axial positions, called of selection, while, when the stem occupies another axial position, called of work, its rotation produces, according to the position previously given to the selector, either the correction of the date indicator alone or the day and date indicators, or the setting of the hands of the timepiece.
  • FIG. 4 y I I PAIENIEDJUL31 I915 3.748.848
  • the present invention has for object a calendar timepiece provided with a control mechanism comprising a stern arranged in such a way as to be able to occupy at least two different axial positions.
  • This timepiece is characterized by the fact that the said mechanism comprises a movable element operating as a selector and which is controlled, at least indirectly, by the said stem, this selector being arranged in such a way as to occupy one or the other of two positions, according the sense of rotation of the said stem when it occupies one of its axial positions, called of selection, while, when the stem occupies another axial position, called of working, its rotation produces, according to the position previously given to the selector, either the correction of the date indicator and/or of the days indicator, or the setting of the hands of the timepiece.
  • FIG. 1 is a plan view of a portion of the first embodiment of a calendar watch.
  • FIG. 2, 3 and 4 are plan views of this first embodiment in three different operating positions.
  • FIG. to 8 are plan views of a portion of four other embodiments of a calendar watch.
  • FIG. 9 to 12 are plan views, in four different operating positions, of a portion of a sixth embodiment of a calendar watch.
  • the calendar watch represented in FIG. 1 to 4 comprises a crown 1, indicating the date, provided with an inner toothing 1a by means of which it is driven intermittently by the gearing of the movement, by means of a mechanism which has not been represented, at the rate of one step per 24 hours.
  • the watch comprises also an indicator 2 of the days, situated in the center of the movement, provided with a toothing 2a by means of which it is driven, once per 24 hours, by the crown l of the date, by the intermediary of a mechanism comprising a star wheel 3 driven by the toothing la of the indicator 1 of the date, and two pawls 4 carried by the wheel 3, cooperating with the toothing 2a.
  • This mechanism constitutes thus a one-way coupling, the indicator 2 of the days being driven by the indicator 1 of the date when this latter is itself driven in its normal sense of rotation by the gearing of the movement or by a manual correcting device which is disclosed hereafter.
  • the indicator of the date is driven in the counter direction by means of the manual correction device, the pawls 4 jump on the toothing 2a of the indicator of the days without driving it.
  • One can thus effect the manual correction either of the two indicators simultaneously, for instance when the date and the days have been lost both following a stopping of the watch, either of the date indicator alone, for instance at the end of the months of 31 days, and this can be obtained according to the sense in which the manual correction mechanism is operated.
  • This mechanism which serves also to the setting of the watch, comprises a stem 5 able to occupy two axial positions, one pushed (FIG. 1 and 2) and the other one pulled (FIG. 3 and 4).
  • This stem 5 carries a sliding pinion 6 the front toothing 6a of which is meshing with a wheel 7 carried by a lever 8 articulated at 9 on the frame of the movement.
  • This lever is submitted to the action of a return spring 10 which tends'to rotate it in the clockwise direction.
  • the lever 8 is provided with a finger 8a engaging the groove, designated by 11, of the sliding pinion 6 so that this latter follows, while sliding on the stem 5, the movements of the lever 8, its toothing 6a thus remaining permanently meshing with the wheel 7.
  • the movement of the lever 8 are controlled by a trigger-piece l2 articulated on the frame of the movement, and which is submitted to the action of a jumper spring 13.
  • This trigger-piece l2 acts on the lever 8 by the intermediary of a lever 14, acting as a selector, articulated at 15 on the frameof the movement.
  • This selector 14 is provided with a beak 14a cooperating with the toothing of the wheel 7.
  • the stem 5 occupying its pushed position, called of selection, represented in FIG. 1 and 2, it can be rotated manually in the sense of the arrow 16 (FIG. 1), that brings the selector 14 into the position of selection represented in FIG. 1, or be rotated in the sense of the arrow 17 (FIG. 2), that brings the selector into the position represented in FIG. 2.
  • the selector 14 when it occupies one or the other of the two above mentioned positions both, called of selection, the selector 14 is returned respectively by the spring 10 of the lever 8 actingthereon by the intermediary of the lever and by a blade spring 18 secured to the trigger-piece 12, so that, in both cases, the extremity of its beak 14a tends to engage the toothing of the wheel 7, so that the selectorbe always submitted to the action of the stem 5 and so that it is sufficient to rotate this stern in one direction or in the other for urging the selector to pass from one of its selection positions into the other.
  • the days indicator 2 being driven only in one sense by means of the one-way mechanism 3-4 as disclosed previously.
  • lever 8 is provided with a finger 8b bearing on one or the other of two pins 22 limiting its displacements.
  • the sliding pinion 6 is prevented from moving axially by two protrusions 23a of the base plate 23 of the frame of the movement. It is however called sliding pinion for the reason that the control stem can slide therein axially.
  • the lever 8 is replaced by a lever 24 articulated at 25 on the frame of the movement, that is to say coaxially to the wheel 7.
  • the wheel 7, in this embodiment does not mesh with the setting wheel, as in the first embodiment, but is meshing with a second wheel, designated by 26, carried by the lever 24, which meshes, when the mechanism occupies its setting position, with the hour wheel 27.
  • This wheel 26 is rigid with the star wheel 21 for the correction of the date, which is meshing, when the mechanism occupies its position of correction, with the inner toothing 1a of the date indicator 1.
