Definitions

  • ABSTRACT A day and date corrector mechanism mounted for pivotable displacement from outside said watch and having [54] DAY AND DATE CORRECT-0R MECHANISM FOR a quadrilateral aperture therein.
  • a corrector wheel lever A WATCH cooperatively engages said quadrilateral aperture for the 3 Chums 4 Drawing as selective positioning of a day and date corrector wheel mounted on said corrector wheel lever.
  • the setting lever is U.S. CL...
  • said corrector wheel lever pivotably displaceable between three ositions at one of H F- --G04b19/24 which said corrector wheel lever may rock between one 0 Search .l o e aflye engagement of corrector whee] for day core 855 rection and another operative connection of said corrector wheel for date correction.
  • said corrector wheel lever is rest zained with UNITED STATES PATENTS the corrector wheel in a neutral position, while winding and 3.093358 58/58 hand setting functions are respectively performed.
  • a winding stem, 2 is a clutch wheel turning cooperatively with the winding stem 1 and conjoining to be able to slide axially
  • 3 is a winding pinion which-transmits the turning, of winding stem I to a crown wheel notshown in the drawings) through the intermediary of clutch wheel 4- Is a" setting lever conjoining with the groove of winding stem 1 and pivoting at the pin 5.
  • .lhc setting lever 4 is provided with the pin do which connects with access sively one of the three notchesof a setting lever spring 7 for positioning.
  • a quadrilateral aperture 4b interlocks with the pin Ila-which projects downwardly below the end of the corrector wheel lever II.
  • I9 is a minute wheel-which cngagoswith the setting whoel'ti, duringhand setting.
  • FIG. I- shows the mechanism according to the invention during stateol winding the msinspring, thatis to say the watch isin the statc'ol usual running.lnthiutate-, when the winding stem I ll turned, whereof rotationv is transmitted from the clutch wheel: to-the windingtwheclii', thc'crown wheel and the ratchet whccllnot shown in-the drawingslarc turned toallow winding ofthe mainspring to take place.
  • the clutch wheel to-the windingtwheclii', thc'crown wheel and the ratchet whccllnot shown in-the drawingslarc turned toallow winding ofthe mainspring to take place.
  • the quadrilateral aperture. in the setting lever A rcstrains the movement of the factors which makes it expansive. Moreover, as the day and date corrector wheel I3 rests always at the neutral position, except during day and date correction, the. said corrector wheel I3 does not disturb the motion of the date dial, or day star and dioidisk.
  • a calendar watch having a longitudinally displaccablc winding stem disposable in at least three predetermined positions, mainspring winding means, hand setting means, day setting and display means, and date setting and display means,
  • the improvement which comprises a pivotable setting lever coupled to-said winding atom for pivoting in response to the longitudinal displacement of said winding stem and being formed with'a quadrilateral aperture therein; a pivotable corrector wheel lover having a portion thereof projecting into said setting lever aperture for guiding the pivotablc displacement of said corrector wheel lever; and a corrector wheel at a third oi said predetermined positions, saidsctting'lovor aperture and corrector wheel lcvcr being placed to retain said corrector wheel in a neutral position out of-operativc engagemom with said day setting and display means and said datc setting and display means when said winding ste'm'is in said first and third oi'said predetermined positions, and-to permit said corrector wheel lever to selectively rock between'a first placement of said corrector wheel in operative engagement with said day settingand display means for day correction and a second placement of said corrector wheel in operative engagement with said day setting and display means for day correetion and a second placement of said corrector
