Definitions

  • This invention relates to a windingand setting device for timepieces and particularly to a device of. this class which is adapted for use with the so-called liuid tight watches.
  • the winding crown is normally held in intimate contact with the watchcase to prevent entrance of any moisture into the clockwork.
  • the object of the invention is the provision of a device of the above mentioned class inwhich an axially movable winding and set ting stem, which as usual operates the main spring of the watch andth-e minute wheel work, will bedisconnected' from both main spring and minute wheel work when the stem is in its innermost position relative to the watch in order to allow the winding crown to be brought int'o' intimate contact with the watch case.
  • Figures 1, 2 and 3 are three tron-t elevations of a winding and setting device according to the invention and showing the same in three different working positions.
  • Fi nre 4 is a partial view of the winding and getting stem.
  • t a 7 Figures 5, 6 and 7 are front elevations of a modified arrangement of winding and setting means showing the parts also in three dif ferent working positions.
  • H1 is the winding stem hav ng agroove '2in which engages a hook 3 of a locking lever 1,
  • This latter is pivoted at 5and is provided with an abutting pin 6 with which is adapted to co-operate one of the three springnotches 7, 8 or 9, of the spring arm 10.
  • 11 is a slid- 0 ing pinion sliding upon a squared portion 12 of the winding rod or stem and adapted to engage either with a winding pinion 13 acting on the main spring or with the setting gear 14 of the minute wheel work;
  • the sliding pinion is, in the usual manner, under the action of an oscillatable lever 15 under the influence of the spring 16.
  • Fig. 1 shows the neutral position or the innermost position of the winding stem or rod.
  • the notch is in engagcment with the pin 6. 1 Supposing thatthe winding crown show-n ⁇ fined on the rod or stem 1, is screwed on to the pendant 0n unscrewing the crown, it can be turned freely and the winding stem and the sliding pinionwillinove with the crown, but the winding stern being separated both from the driving barrel as well as from the time setting wheels will turn freely.
  • the invention is of course not limited to the winding of watches with a sliding pinion and a lever, it may also be applied to watches wound by a push mechanism or by a rocking lover or to other types of watches.
  • the lever 27 is provided with a spur 39 intended to co-operate with a supporting surface 40, constituted as an arc of a circle which is formed by the oscillating lever 30, the center of this circular arc being on the pivotal axis 28 of the lever 27.
  • the extremity of the surface 40 on the oscillatable lever 30 is provided with a recess 41 followed by a nose 42.
  • the operation is as follows.
  • Fig. '5 shows the normal position in which the crown 23 is completely screwed to the pendant.
  • the spur 39 of the lever 27 is thenin contact with the supporting surface 40 of the oscillatable lever 30 and maintains this lever in opposition to its spring 32 in a position in which the sliding pinion 11 is not in engagement either with the winding pinion. or with the setting mechanism 14.
