Description

  

  Mouvement de montre à quantième.    L'objet de l'invention est un mouvement  de montre à quantième qui offre cette parti  cularité que la roue de canon porte un doigt  flexible qui entraîne à chaque tour de la roue  de canon; un renvoi denté engrenant dans la  roue de quantième.  



  Le dessin ci-joint montre, à titre d'exem  ple, une forme d'exécution de l'objet de l'in=  v     ention.     



  La roue de canon 1, entraînée par le pi  gnon 2 du renvoi de minuterie 3, porte un  doigt flexible 4, c'est-à-dire ce doigt fait res  sort dans son plan de rotation. Le doigt 4  entraîne d'une dent le renvoi denté 5, à cha  que tour de la roue de canon 4 qui tourne à  raison d'un tour en douze heures. Le renvoi  5 engrène dans la roue de quantième 6 montée  à frottement gras sur un tenon 7. Le canon  de la roue 6 porte l'aiguille 8 marquant le  quantième sur une graduation appropriée du  cadran de la montre. Le doigt 4 étant flexi  ble, il est possible de mettre à jour l'aiguille  de quantième 8, même si le doigt 4 se trouve    en prise avec le renvoi 5; on évite également  l'inconvénient de l'accotement du     doigt    4.  



  Ce mécanisme de quantième peut être ap  pliqué à des mouvements de montres de cons  truction habituelle, sans qu'il soit nécessaire  d'apporter des modifications au calibre; sa  construction est plus simple que celle des mé  canismes de quantième connus, car il ne com  porte ni étoiles ni sautoirs.



  Calendar watch movement. The object of the invention is a date watch movement which offers this feature that the barrel wheel carries a flexible finger which drives the barrel wheel on each revolution; a toothed transmission meshing with the date wheel.



  The accompanying drawing shows, by way of example, one embodiment of the object of the invention.



  The cannon wheel 1, driven by the pin 2 of the timer 3, carries a flexible finger 4, that is to say this finger made res out in its plane of rotation. The finger 4 drives the toothed gear 5 with one tooth, with each revolution of the barrel wheel 4 which rotates at the rate of one revolution in twelve hours. The reference 5 meshes with the date wheel 6 mounted with heavy friction on a tenon 7. The barrel of the wheel 6 carries the hand 8 marking the date on an appropriate graduation of the watch dial. The finger 4 being flexible, it is possible to update the date hand 8, even if the finger 4 is in engagement with the reference 5; the disadvantage of the shoulder of the finger 4 is also avoided.



  This date mechanism can be applied to watch movements of usual construction, without it being necessary to make changes to the caliber; its construction is simpler than that of known date mechanisms, since it does not include stars or necklaces.
