Description

  

  Mouvement de     montre    comprenant deux     barrillets-moteurs       La présente invention a pour objet un mou  vement de montre comprenant deux     barillets-          moteurs,    par exemple un mouvement de mon  tres à réveil dans lequel un barillet commande  le mouvement de montre proprement dit, tan  dis que l'autre actionne la sonnerie du réveil.  



  On a déjà proposé un mouvement de mon  tre muni d'un mécanisme de remontage ac  tionnant en même temps les deux rochets des  barillets-moteurs, ces rochets étant montés fous,  chacun sur l'arbre de barillet correspondant, et  entraînant cet arbre     rotativement    par friction.  Ce mécanisme donne satisfaction, mais prend  beaucoup de place en hauteur.  



  Le mouvement de montre suivant l'inven  tion remédie à cet inconvénient. Il est caracté  risé par un mécanisme de remontage présen  tant une roue qui engrène simultanément et en  permanence avec le rochet de chacun des     ba-          rillets-moteurs,    ces rochets étant calés chacun  sur l'arbre de barillet correspondant, et par  une bride     glissante    fixée à chaque ressort en  vue de permettre de remonter ceux-ci en  même temps par l'intermédiaire de ladite roue,  tout en évitant de provoquer leur rupture au  moment où l'un ou les deux ressorts sont armés  à fond.    Le dessin annexé représente, à titre  d'exemple, une forme d'exécution de l'objet de  l'invention.    La     fig.    1 en est une vue en plan schéma  tique.  



  La     fig.    2 est une coupe suivant la ligne  <I>11-1l</I> de la     fig.    1.  



  Le dessin représente partiellement un mou  vement de montre à réveil comprenant deux  barillets 1 et 2 dont les ressorts respectifs 3  et 4 sont remontés simultanément en action  nant un remontoir à main à l'aide d'une cou  ronne de remontoir non représentée dont la  tige 5 commande un pignon de remontoir 6  engrenant dans une roue de couronne 7 mon  tée sur la platine 8 au moyen d'une vis à por  tée 9.  



  La roue de couronne 7 engrène en même  temps dans deux rochets de barillets 10 et 11  ajustés à carré sur les arbres de barillets res  pectifs 12 et 13 et maintenus     axialement    par  des vis 14 et 15. Les arbres 12 et 13 pivotent  dans la platine 8 et dans un pont 16.  



  Une bride glissante 17, respectivement 18,  de type usuel, est fixée à chacun des ressorts  3, 4 et coopère de façon connue avec la paroi  intérieure du tambour des     barillets    1, 2.  



  Un cliquet de retenue, non représenté, co  opère avec la denture de l'un des mobiles 7,  10 ou 11.  



  Si l'on fait tourner la tige de remontoir 5  suivant le sens de remontage des ressorts de  barillets 3, 4, la roue de couronne 7     entraîne         les deux rochets 10, 11 et, par suite, les arbres  de barillets 12, 13, ce qui arme simultanément  les deux ressorts 3, 4. Si l'un de ces ressorts  est armé à fond, sa bride se met à glisser à  l'intérieur du tambour de barillet correspon  dant. Quant à l'autre barillet, l'action de re  montage pourra continuer jusqu'à ce que le  ressort-moteur soit à son tour armé à fond.

    Au moment où l'un ou les deux     ressorts-          moteurs    sont armés à fond, il est possible de  continuer indéfiniment de tourner la tige de  remontoir, sans risquer de forcer ces ressorts  ni de provoquer le rebattement du balancier ou  des dégâts dans le rouage.  



  On voit que le mécanisme décrit et repré  senté ne prend pas plus de place en hauteur  qu'un mécanisme de remontoir ordinaire.  



  Au lieu d'être un remontoir à main, le mé  canisme de remontage pourrait aussi être un  remontoir automatique.



  Watch movement comprising two motor barrels The present invention relates to a watch movement comprising two motor barrels, for example a watch movement in which a barrel controls the actual watch movement, tan say that the watch movement other activates the alarm clock.



  A movement of my own has already been proposed which is provided with a winding mechanism actuating at the same time the two ratchets of the motor barrels, these ratchets being mounted idle, each on the corresponding barrel shaft, and driving this shaft rotatably by friction. This mechanism is satisfactory, but takes up a lot of space in height.



  The watch movement according to the invention overcomes this drawback. It is characterized by a winding mechanism having a wheel which engages simultaneously and permanently with the ratchet of each of the motor pistons, these ratchets each being wedged on the corresponding barrel shaft, and by a sliding flange fixed. to each spring in order to allow them to be raised at the same time by means of said wheel, while avoiding causing them to break when one or both springs are fully loaded. The appended drawing represents, by way of example, an embodiment of the object of the invention. Fig. 1 is a tick diagram plan view.



  Fig. 2 is a section taken along the line <I> 11-1l </I> of FIG. 1.



  The drawing partially represents an alarm watch movement comprising two barrels 1 and 2, the respective springs 3 and 4 of which are wound up simultaneously in action, creating a hand winding using a winding crown, not shown, the stem of which 5 controls a winding pinion 6 meshing with a crown wheel 7 mounted on plate 8 by means of a screw with bearing 9.



  The crown wheel 7 engages at the same time in two ratchets of barrels 10 and 11 adjusted squarely on the respective barrel shafts 12 and 13 and held axially by screws 14 and 15. The shafts 12 and 13 pivot in the plate 8 and in a bridge 16.



  A sliding flange 17, respectively 18, of the usual type, is fixed to each of the springs 3, 4 and cooperates in a known manner with the inner wall of the drum of the barrels 1, 2.



  A retaining pawl, not shown, co-operates with the teeth of one of the wheels 7, 10 or 11.



  If the winding stem 5 is rotated in the winding direction of the barrel springs 3, 4, the crown wheel 7 drives the two ratchets 10, 11 and, consequently, the barrel shafts 12, 13, this which simultaneously arms the two springs 3, 4. If one of these springs is fully loaded, its flange begins to slide inside the corresponding barrel drum. As for the other barrel, the reassembly action can continue until the mainspring is in turn fully charged.

    When one or both mainsprings are fully charged, it is possible to continue turning the winding stem indefinitely, without running the risk of forcing these springs or causing the balance rebound or damage to the gear train.



  It can be seen that the mechanism described and represented does not take up more space in height than an ordinary winding mechanism.



  Instead of being a hand winder, the winding mechanism could also be an automatic winder.
