Description

  

  Mouvement de montre à remontage     automatique.       L'objet. de la présente invention est un  mouvement de montre à remontage automati  que dans lequel l'arbre du barillet est. pivoté  dans un pont. indépendant sous lequel est  situé le rochet de barillet, aucun point de  fixation des autres organes du mécanisme de       remontage    automatique n'étant situé sur ledit  pont. indépendant.    Le dessin annexé représente un mouve  ment de montre constituant une     forme        d'exé-          eution    de l'objet de l'invention et décrit ci  après à titre d'exemple.    ment de la montre au moyen de pieds 7 et  d'une vis unique 8.

   Ces derniers éléments sont  les seuls éléments de fixation de la masse au  mouvement et. ont .leur point de fixation.  comme du reste les autres organes du méca  nisme de remontage automatique (vis 9 et  axes 10 de la bascule et du rochet. 4), en  dehors .du pont de barillet 11. Celui-ci est  donc indépendant et     maintient,    par ses deux  vis de fixation 12, seulement le barillet 13 et  son rochet 14 situé sous ledit pont     (fig.    2)  ainsi qu'une lame 15 formant le ressort du  cliquet de rochet.    La     fig.    1     est    une vue en plan de ce mou  vement.    La     fig.    2 en est une coupe partielle selon  la ligne brisée     II-II    de la     fig.    1.  



  La masse de remontage 1 du mouvement  représenté est pivotée sur un tourillon 2 et  entraîne avec elle la came 3 par l'intermé  diaire de laquelle se fait le remontage. Les  mouvements de rotation de la came 3 sont.  transmis à un rochet auxiliaire 4 du méca  nisme de remontage automatique     par    l'inter  médiaire d'une bascule portant deux cliquets  en prise avec le rochet. auxiliaire et l'entraî  nant toujours dans le même sens.  



  Le tourillon 2     est    assujetti à l'extrémité  libre d'une languette recourbée 5 solidaire  d'un talon massif 6 fixé au bâti du mouve-    Comme le rochet 14 est placé sous le pont  11, la vis de fixation du rochet est inutile  et le pivot 16 de l'arbre de barillet     dans    le  pont 11 peut être d'un diamètre notablement  plus petit. que si cet arbre .devait supporter  le rochet sur le pont. 11 et être taraudé pour  recevoir la vis de fixation.  



  Pour faciliter l'enlèvement du pont de  barillet 11, celui-ci est échancré en 17, confor  mément au profil de la languette recourbée 5.



  Self-winding watch movement. The object. of the present invention is a self-winding watch movement in which the barrel shaft is. rotated into a bridge. independent under which the barrel ratchet is located, no attachment point for the other members of the automatic winding mechanism being located on said bridge. independent. The accompanying drawing represents a watch movement constituting one embodiment of the object of the invention and described below by way of example. the watch by means of feet 7 and a single screw 8.

   These last elements are the only elements of attachment of the mass to the movement and. have .their point of attachment. like the rest of the other parts of the automatic winding mechanism (screws 9 and pins 10 of the lever and the ratchet. 4), apart from the barrel bridge 11. The latter is therefore independent and maintains, by its two screws fixing 12, only the barrel 13 and its ratchet 14 located under said bridge (Fig. 2) and a blade 15 forming the spring of the ratchet pawl. Fig. 1 is a plan view of this movement. Fig. 2 is a partial section along the broken line II-II of FIG. 1.



  The winding mass 1 of the movement shown is pivoted on a journal 2 and drives with it the cam 3 through which the winding takes place. The rotational movements of cam 3 are. transmitted to an auxiliary ratchet 4 of the automatic winding mechanism via a lever carrying two pawls engaged with the ratchet. auxiliary and always pulling it in the same direction.



  The journal 2 is secured to the free end of a curved tongue 5 integral with a solid heel 6 fixed to the frame of the movement. As the ratchet 14 is placed under the bridge 11, the fixing screw of the ratchet is unnecessary and the pivot 16 of the barrel shaft in bridge 11 may be of a significantly smaller diameter. only if this tree had to support the ratchet on the bridge. 11 and be tapped to receive the fixing screw.



  To facilitate removal of the barrel bridge 11, the latter is indented at 17, conforming to the profile of the curved tongue 5.
