Description

  

      Palier    pour l'arbre de barillet d'une montre.    Dans le rhabillage des montres il a fallu,  jusqu'ici, dévisser le pont de barillet si on  voulait extraire le barillet, par exemple pour       remplacer    un ressort cassé. A     cette    occasion,  tout le     mécanisme    que porte ce pont a de  même dû     être    démonté. Cela amenait une       perte    de temps et des frais sérieux, surtout  lors du     rhabillage    de montres avec seconde au  centre et roue de     transmission        supplémen-          taire.     



  Cet inconvénient est éliminé par le palier  de l'arbre de barillet selon     l'invention,    palier       caractérisé    en -ce     qu'il    comporte un     coussinet     solidaire d'un     support    élastique     maintenant          ledit        coussinet    au fond d'une encoche du  pont du barillet     permettant    le passage de  l'axe du barillet et     l'extraction    de     ce        barillet.     



  Le dessin représente, à     titre    d'exemple,  une forme d'exécution de l'objet de l'inven  tion..  



  La     fig.1    est une vue de dessus, le rochet  de barillet et sa     vis    étant enlevés, et  la     fig.2    est une coupe     suivant    la ligne       II-II    de la     fig.1.     



  L'arbre 1 du     barillet    2 tourne dans un       coussinet    3 de la     platine    4 du mouvement de  la montre et dans un     coussinet    5. Ce dernier  est une bague chassée     dans    une     lame-ressort    6  faisant support     élastique.    La     lame-ressort    a  une     tension    initiale telle que, placée sur le  fond d'un évidement 7     dans    le pont de ba  rillet 8, la lame est légèrement cintrée vers  le haut dans sa. partie médiane. Pourtant, une  vis de pont 9 la fait reposer     @de    tout son long    sur le fond de l'évidement 7.

   Il est prévu un  faible jeu latéral de la lame 6 dans son évide  nient. Le centrage du coussinet 5 et de  l'arbre de barillet 1 est assuré par son emboîte  ment dans un alésage 10 du pont 8. Un  évidement 11 est prévu dans la     platine    4 et  le pont 8. La     distance    entre ses côtés laté  raux 12 est légèrement supérieure au     @dia-          mètre        maximum    du     barillet.    Le pont du ba  rillet présente une encoche dont le fond est       constitué    par l'alésage 10 et dont les côtés 14  ont un     écartement    qui dépasse faiblement le  diamètre maximum de l'arbre du barillet.

   La,  hauteur de     l'encoche    11 est telle     qu'il    y ait  un jeu 15 entre le barillet et le pont légère  ment plus grand que -la longueur du bout de  l'arbre     tournant        dans    le     coussinet    3.  



  A l'état assemblé du mouvement, le palier  décrit maintient l'arbre de barillet en le te  nant dans le     coussinet    3 de la platine et son  propre     coussinet    5.  



  Pour extraire le     barillet,    on     enlève    la     vis        cle          rochet    16, le rochet 17 et on desserre la     vis    de       pont   <B>9.</B> Maintenant, on peut hausser et     extraire     le barillet avec son arbre sans     qu'il    faille dé  monter son pont et tout le mécanisme que  porte ce dernier, en le passant par l'encoche 11.  Le montage est tout     aussi    simple et se fait en       sens    inverse.



      Bearing for the barrel shaft of a watch. In the refurbishment of watches, it has been necessary, until now, to unscrew the barrel bridge if we wanted to extract the barrel, for example to replace a broken spring. On this occasion, the entire mechanism carried by this bridge also had to be dismantled. This was a waste of time and serious expense, especially when re-dressing watches with a central seconds hand and an additional transmission wheel.



  This drawback is eliminated by the bearing of the barrel shaft according to the invention, a bearing characterized in that it comprises a bearing secured to an elastic support holding said bearing to the bottom of a notch of the barrel bridge allowing the passage of the barrel axis and the extraction of this barrel.



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



  Fig.1 is a top view with the barrel ratchet and its screw removed, and Fig.2 is a section taken along line II-II of Fig.1.



  The shaft 1 of the barrel 2 rotates in a bearing 3 of the plate 4 of the watch movement and in a bearing 5. The latter is a ring driven into a leaf spring 6 forming an elastic support. The leaf spring has an initial tension such that, placed on the bottom of a recess 7 in the bay bridge 8, the leaf is slightly bent upwards in its. middle part. However, a bridge screw 9 rests it full length on the bottom of recess 7.

   A slight lateral play of the blade 6 is provided in its recess. The centering of the bearing 5 and of the barrel shaft 1 is ensured by its engagement in a bore 10 of the bridge 8. A recess 11 is provided in the plate 4 and the bridge 8. The distance between its lateral sides 12 is slightly greater than the maximum diameter of the barrel. The bay bridge has a notch whose bottom is formed by the bore 10 and whose sides 14 have a spacing which slightly exceeds the maximum diameter of the barrel shaft.

   The height of the notch 11 is such that there is a clearance 15 between the barrel and the bridge slightly greater than the length of the end of the rotating shaft in the bearing 3.



  In the assembled state of the movement, the bearing described maintains the barrel shaft by holding it in the bearing 3 of the plate and its own bearing 5.



  To extract the barrel, we remove the ratchet screw 16, the ratchet 17 and we loosen the bridge screw <B> 9. </B> Now, we can raise and extract the barrel with its shaft without having to assemble its bridge and all the mechanism carried by the latter, passing it through notch 11. Assembly is just as simple and is done in reverse order.
