Definitions

  • the stem When the stem is pulled out from the pushed-in position to the intermediate position, it is connected to the date ring which can be set in both directions, and when the stem is pushed in from the pulled-out position to the intermediate position it is connected to the day-star wheel which can also be set in both directions.
  • the invention relates to timepieces of the type including a device for setting the indications of a plurality of indicating members, in particular supplementary in dicating members such as a date ring, a day-star wheel, an hour indicator the angular position of which may be changed by one hour upon passing from one time zone to the next, and an alarm-setting indicator.
  • timepieces including devices of this type are known, generally including an actuating stem, such as the hour-setting and winding stem, which can be placed in three discrete axial positions one of which, usually the intermediate position, is reserved for the setting of supplementary indicating member.
  • the setting of two indicating members in the intermediate position has already been proposed by arranging for the stem to be operatively connected with a first member when the stem is turned is one direction and with a second member when the stem is turned in the other direction.
  • An object of the invention is to provide a timepiece with an indicator-setting device which avoids the stated drawbacks, and which more particularly enables the selective control of a bi-directional setting of two indicating members in a single intermediate axial position of the stem.
  • the invention concerns a timepiece including a plurality of indicating members and a device for setting the indications of said members, said device comprising a manually operable rotatable and axially displaceable actuating stem, and means for defining three discrete axial positions of the stem namely a pushed-in position, an intermediate position in which the stem is operatively connected with at least one indicating member for actuation thereof by rotation of the stem, and a pulled-out position.
  • the invention provides the improvement comprising means for selectively operatively connecting said stem in said intermediate position with a first indicating member in response to pulling out of the stem from the pushed-in position to the intermediate position and with a second indicating member in response to pushing in of the stem from the pulled-out position to the intermediate position.

  • the setting lever 4 also controls the movement of another lever 2t" pivotally mounted about arbor 23"a and carrying a toothed wheel 22" which permanently meshes with pinion 23".

  • the described device enables both positive and negative corrections to the rate of running of the timepiece, i.e., either to speed it up or slow it down. Moreover, it is simple and convenient to manipulate. Also, correction of the date is a relatively more frequent operation, and this can be achieved simply by pulling out the actuating stem to the intermediate position and then turning it. To correct the rate of running, the actuating stem is pulled fully out, then pushed back in to the intermediate position and turned in the appropriate direction,
