Definitions

  • the present invention relates to a calendar timepiece, and more particularly to a calendar timepiece with a socalled instantaneous advance of the date indicator.
  • the control members of the date indicator may be put out of order if a manual adjustment of the date is effected while the so-called instantaneous mechanism is being prepared to operate, a preparation which lasts a certain time.
  • the timepiece comprises, in combination, a movement, a date-indicator and a mechanism comprising a control member arranged to drive said date indicator intermittently, a driving wheel making one turn in 24 hours, elastic connecting means intermediate said driving wheel and said control member, displaceable stop means against which said control member comes into abutment before coming into engagement with said date indicator, the displacements of said stop means being controlled by the timepiece movement in such a way that when said stop releases the control member, the latter, under the action of the elastic connecting means which is cocked during arrest of the control member, eflFects an abrupt displacement thereby driving the date indicator one step, in one so-called instantaneous jump.
  • FIGURE 1 is a plan view of a part of a timepiece, showing only the members necessary for the comprehension of the invention, and
  • FIGURE 2 is a cross-section along the line II--II of FIGURE 1.
  • the timepiece shown comprises a date crown wheel 1 for indicating the date mounted rotatably on the frame of the movement, on which are borne the indications 2 of the dates, of which only a part has been shown.
  • the positioning of the crown wheel 1 is ensured by a jumper 3 pivoted at 4 on the frame of the movement and subjected to the action of a return spring 5 which tends to apply it against an internal tooth 6 of the crown wheel 1.
  • the disc 7 carries a pin 13 traversing an opening arranged as a circular are 14 in the wheel 9 which carries a pin 15.
  • the two pins 13 and 15 serve as support points for the ends of a spring 16 rolled around a swivel pin 17 borne by the support plate, designated by 18, of the movement, and on the terminal part 17a on which is engaged the sleeve 8.
  • the mechanism includes a rocker 19 pivoted at 20 on the frame of the movement, having a fork between the branches 19a and 19b with which is engaged an eccentric So on the sleeve 8. This eccentric thus turns with the wheel 9 to which it is rigidly attached.
  • the branch 19a of the fork of the rocker 19 has a projection 19c carrying a pin 21, with a flat end, constituting a stop for the control finger 7a, in certain positions of the rocker 19.
  • the disc 7 In normal operation, the disc 7 is driven by the wheel 9, in the direction of the arrow 22 (FIGURE 1), through the spring 16, which is not cocked. In the course of this rotation, the control finger 7a of the disc 7 meets the pin 21 and comes into abutment against it. The wheel 9 continues then to turn alone, cocking the spring 16.
  • the eccentric 8a causes the rocker 19 to rock around its axis 20, in the contrary direction to that of the hands of a watch, so that the pin 21 is displaced, to tree passage for the finger 7a.
  • the members have been shown in FIGURE 1 in a position a little prior to this operation.
  • the control finger 7a is then freed and, under the action of the spring 16, effects an abrupt displacement in the direction of the arrow 22, in the course of which it acts on the teeth 6 of the date crown wheel 1 to advance it by one step.
  • a calendar timepiece movement having an instantaneous advance date indicator
  • the mechanism for producing the instantaneous advance comprises: a control member adjacent and intermittently driving the date indicator, a driving wheel coaxial and on a common shaft with the control member and making one rotation each 24 hours, elastic connecting means intermediate and supported by the driving wheel and control member, displaceable stop means disposed adjacent for abutment by the control member preliminary to engagement with the date indicator, a rocker pivoted on the movement and carrying the stop means, and an eccentric driven by the movement for controlling displacements of the rocker with the stop means releasing the control member and with the connecting means cocking during arrest of the control member enabling the control member under the action of the connecting means to effect an abrupt displacement for driving the date indicator one step in an instantaneous jump.
  • the elastic connecting means comprising a spring circumscribing the shaft of the driving wheel and control member and having one end bearing against a pin carried by the control member and the other end bearing against a pin carried by the driving wheel, with an arcuate opening in the control member traversed by one of the pins.
  • a timepiece mechanism including jumper means for ensuring the stability of the date indicator in its stationary positions with the control member acting on the jumper means for disengaging the jumper means from the date indicator as the latter is actuated.
  • the rocker including a fork between the branches of which the eccentric is engaged with at least one of the branches being elastic so as to yield when resetting the time of the movement is effected in a reverse direction and the rocker is displaced by the control member of the date indicator being urged against the stop means.
  • control member includes a ramp-shaped cam surface which engages a rounded rear surface of the stop means in the course of the resetting in reverse direction thereby displacing the rocker.
