Definitions

  • This invention relates to calendar-featuring timepieces, such as calendar watches. It relates more particularly to control systems for such devices.
  • the calendar-indicating system is immobilised by a jumper spring and may, under the effect of a shock, undergo a spontaneous displacement of up to several days.
  • the locking means comprises a spring-loaded pivoting lever which is provided with a locking finger engaging the teeth of the calendar-indicating ring and a projection co-operating with a wheel driven by the movement of the watch, said projection being adapted to cause the locking lever to pivot, thereby releasing the indicator only at the instant when it is actually driven and to liberate the lever again, at least partially, immediately following the advance of the indicator.
  • such a time-piece is provided with kinematically interconnected driving and locking means and is characterised in that the driving means is rotatively intercoupled with a beak adapted to engage a projection on the lever.
  • FIG. 1 is a plan view of the device.
  • FIG. 2 is a sectional view taken along the line X- XY.
  • FIG. 3 is a sectional view taken along the line Y-Y.
  • a calendarindicating ring 1 which is provided along its internal periphery with teeth 2 and is driven by a pin 3 which is integral with a beak 4.
  • the beak 4 is rotatively supported at 5a by a screw 5 mounted on a plate I6.
  • a driving wheel 7 driven by the calendar wheel pinion.
  • the pin 3 is formed with an upwardly extending shoulder 3a which serves as the actual driving element for the calendar ring 1 and a projection 3b extending downward and engaging an arcuately shaped slot 8 formed in the driving wheel 7.
  • the locking of the calendar ring is achieved by means of a projection 11 formed on a locking lever 12.
  • the latter is pivotably mounted at 13 and is loaded by means of spring 15.
  • the locking lever 12 has a projectiony 16 defined by the curved portion 17. This projection terminates in a shoulder 18 against which abuts the beak ⁇ 4. On the other hand, projection 11 is formed with an arcuately shaped clearance 19 to provide free passage for beak ⁇ 4. The latter also passes freely under the teeth of the indicator ring.
  • the pin 3 follows the movement of wheel 7 through the intermediary of the portion 3b.
  • lever 12 may be of any different configuration, provided its configuration meets the necessary conditions for a correct mutual co-operation with the beak 4.
  • the elements 3 and 4 may be fabricated as a single piece, as shown in the drawing, or also in two pieces, the portion 3a and 3b being formed by the ends of a vertical pin.
  • a timepiece with date-indicating mechanism the combination of a rotatable date-indicator ring having teeth on its inner periphery, date-indicator ring advancing means comprising a driving pin engageable with a tooth of said ring to advance said ring, driving means for actuating said advancing means to advance said ring one date unit, a pivoted locking lever having a locking projection engageable with the teeth of said ring, said locking lever being movable between a locking position in which said locking projection engages a tooth of said ring to hold said ring stationary and a released position in which said locking projection is withdrawn to clear said ring, spring means biasing said locking lever to hold said locking lever normally in locked position, said advancing means further comprising ⁇ a beak engaging a shoulder n said locking lever to pivot said locking lever to released position only when said advancing means is actuated to advance said date-indicating ring.
  • a time-piece according to claim 1, wherein said advancing means comprises a unit-ary rotatable member having a portion comprising said driving pin and a second portion comprising said beak.
  • said driving means comprises a driving wheel coaxial with 4 said rotatable mem-ber and having an arcuate slot in ywhich said driving pin engages.
  • said driving means further comprises a pivoted lever having an inclined cam edge engageable with said driving pin and spring means biasing said pivoted lever toward said driving pin to advance said pin in said slot when said pin reaches said inclined cam edge during rotation of said driving wheel.
