Definitions

  • the present invention relates to an improved calendar watch and a novel day and date correcting mechanism therefor. More particularly, the instant invention relates to a novel day and date correcting mechanism which is operatively connected to the calendar watch winding stem.
  • Calendar watches of the type with which this invention is concerned typically have a date wheel, a daily star secured to a day disk and a day and date advancing member.
  • the day and date advancing member usually includes day and date advancing wheels and secured thereto, day and date indexing fingers for indexing the date wheel and daily star to next successive calendar display positions.
  • a pair of jumpers are usually provided for contacting the gear portions of the date wheel and daily star.
  • the day and date advancing member is rotated by a wheel train operated by a suitable source of energy such as a cell or mainspring. Rotation of the day and date advancing member causes rotation of the date wheel and daily star by means of respective day and date indexing fingers.
  • the jumpers exert only enough force against the date wheel and daily star, respectively, to cause them to make the desired indexing movement quickly.
  • the instant invention provides a simplified, inexpensive and sturdy mechanism for making day-date corrections to calendar watches.
  • a calendar watch of the type having a rotatable winding stem selectively axially displaceable into plural predetermined positions, a rotatable date wheel and a rotatable daily star is provided having discrete first and second means for independently operatively connecting, respectively, the winding stem with the date wheel and daily star in one predetermined position thereof for selective consecutive rotation of the date wheel in response to the rotation of the winding stem in one direction, and selective intermittent rotation of the daily star in response to a rotation of the winding stem in the other direction.
  • Another object of the invention is to provide a calendar watch for a day-date correcting mechanism having a reduced number of parts.
  • FIG. 1 is a fragmentary top plan view of an embodiment of the calendar watch according to the invention disposed in the first or winding position thereof;
  • FIG. 2 is a fragmentary top plan view of the embodiment shown in FIG. 1 disposed in the second or daydate correcting position thereof;
  • FlGS. 3a and 3b are fragmentary detail views of the day correcting means of the embodiment shown in FIG. 2 disposed, respectively, in operative and inoperative positions thereof;
  • FIG. 4 is a fragmentary top plan view of another embodiment of a day correcting means for a calendar watch constructed in accordance with the invention.
  • FIG. 5 is a fragmentary top plan view of yetanother embodiment of a day correcting means for a calendar watch constructed in accordance with the invention.
  • FIG. 6 is a fragmentary top plan view of the embodiment of FIG. 2 disposed in the third or time-correcting position thereof;
  • FIGS. 7a, 7b and 7c, 7d are respective. sideelevational and cross-sectional views of alternate clutch means that may be employed in the datecorrecting means of the calendar correction mechanism of the invention.
  • the calendar correcting mechanism corrects the day and/or date indication on the calendar indication display from outside of the watch, as by a stem.
  • both the day and date adjusting functions are performed by the pulling or turning of the stem.
  • the stem has three positions. The first of these positions is a free or usual carrying state, usually set aside for performing the winding function.
  • the second position of the winding stem displaced from the first position, is set aside for day and/or date correction.
  • the time indication display is stopped and that display may be manually corrected.
  • the hands may be set.
  • the first position of the calendar correcting mechanism is depicted in FIG. 1.
  • the calendar correcting mechanism includes a stem 1 having a clutch wheel 6 mounted thereon for axial displacement therealong.
  • a setting lever 2 is pivotably mounted on the watch plate (not shown) and has a projection which rides in a groove in stem 1 for pivotal displacement of the setting lever in response to the axial displacement of the stem.
  • a clutch lever 4 is also pivotably mounted on the watch plate and engages in a circumferential groove in clutch wheel 6 for the axial positioning of the clutch wheel along the winding stern.
  • Anotched clutch lever spring 3 is provided for engaging a further projection mounted in setting lever 2 for the precise positioning of the setting lever.
  • Clutch lever 4 is biased in the counterclockwise direction, as
  • a day correcting lever 12 is pivotably mounted on the watch plate by a pivot pin 13 and is provided with lever arms 12a and 120.
  • Day correcting lever 12 is biased in the clockwise direction, as viewed in FIG. 1, by the force of a day correcting lever spring, so that the day correcting lever engages a stopper and is positioned thereby.
  • the day and date displays may be consecutively corrected by respectively axially displacing the winding stem 1 into the second position and alternately axially rotating stem 1 in the direction of arrow 11 and then in the direction of arrow 10.
  • clutch wheel 6 is rotated in the direction of arrow 10
  • date wheel 8 is thereby rotated for correcting the date display.
  • projection 60 mounted thereon engages the rear plane surface of arm 12a of day correcting lever 12.
  • lever 12 is provided with a prevent member 12b for preventing the rotative displacement of the date wheel during an operational sequence for the rotative displacement of the daily star. While in the usual case, the gear teeth 6a of clutch wheel 6 will frictionally slide over the gear teeth of date wheel 8 without advancing the date wheel as stem 1 is rotated in the direction of arrow 11 because date wheel 8 is usually provided with a date jumper (not shown) for preventing the incremental rotation of the date wheel in the reverse direction if the distance traveled in the reverse direction is less than a first predetermined distance, it is possible for the date jumper to fail.
  • lever 12 is provided with a prevent member 12b and as lever 12 is pivoted to engage daily star 14 for day correction, prevent member 12b is displaced to the position shown in phantom line in FIG. 2 for preventing any rotation of date wheel 8 beyond an incremental distance.
  • projections 60 mounted on clutch wheel 6 may be replaced with projections 600 which are selectively mounted on clutch wheel 6 so that they do not bend lever arm 12a out of the plane of lever 12 during a date correction while they are sufficiently aligned with lever 12 for pivoting lever 12 during a day correction sequence.
  • FIG. 5 shows another embodiment of the invention wherein lever 12 is provided with a different configuration and acts through a second pivotably mounted lever 15 responsive to the pivot of lever 12 for rotatingdaily star 14.
  • FIGS. 70, 7b and 7c, 7d different clutch wheel embodiments maybe employed for effecting day and date corrections in accordance with the invention.
  • FIGS. 7a and 7b are illustrative of one clutch wheel embodiment and FIGS. and 7d are illustrative of a second clutch wheel embodiment.
  • day and date corrections may be effected by pulling the winding stem of the timepiece to the second of three positions and each correction may be performed without disturbing the display in general.
  • the time display on the face of the timepiece may be corrected by pulling the winding stem to its third position. Correction of the time display does not in any way interfere with the day and date displays.
  • a calendar watch having a rotatable winding stem selectively axially displaceable into plural predetermined positions, a rotatable date wheel and a rotatable daily star
  • the improvement comprising discrete first and second means for independently operatively connecting, respectively, said winding stem with said date wheel and said daily star in one of said plural predetermined positions of said winding stem for selective consecutive rotation of said date wheel in response to a rotation of said winding stem in one direction, and selective intermittent rotation of said daily star in response to a rotation of said winding stem in said other direction
  • said second means for operatively connecting said winding stem with said daily star including a lever means mounted for pivoting into operative intermittent engagement with said daily star for rotatively displacing said daily star in response to said rotation of said winding stem in said other direction, pivoting means arranged on said winding stem for fixed rotation therewith, said pivoting means being intermittently engageable to said lever means when said winding stem is displaced at one of said plural predetermined positions, said pivoting means being operatively
  • said first means for operatively connecting said winding stem with said date wheel includes a clutch means coaxially arranged on said winding stem for fixed rotation therewith, said clutch means being connected to said date wheel in said one of said plural predetermined positions of said winding stem, said connection being operative for rotative displacement of said date wheel in response to said rotation of said winding stem in said one direction and said connection being inoperative for rotative displacement of said date wheel in response to said rotation of said winding stem in said other direction.
