Description

  

  Montre à seconde au centre.    La présente invention a pour objet une  montre à seconde au centre.  



  Le dessin annexé représente, à titre  d'exemple, une forme d'exécution de l'objet  (le l'invention.  



  lia     fi,ure    unique en est une vue en plan,  seuls les ,éléments nécessaires à la compréhen  sion de l'invention étant représentés.  



  Le rochet. de barillet est désigné par le  chiffre 1 et tourne dans le sens de la flèche A  quand on remonte le mouvement. Le cliquet 2  du rochet de barillet porte une goupille 3  agissant, loris du remontage du mouvement,  contre une came 4 solidaire d'un marteau 5  de remise à zéro. Le marteau 5 pivote en 6.  



  Dans la position de repos du mécanisme,  représentée en traits pleins, le     coeur    7, por  tant l'aiguille de seconde, peut tourner libre  ment, entraîné par le rouage de la montre.  



  Si l'on remonte le mouvement, le cliquet 2  prend la position montrée en traits mixtes;    la. goupille 3 actionne la came 4 et, par suite,  le marteau 5 vient s'appliquer sur le     coeur    7  et ramène à zéro l'aiguille de seconde. L'ai  guille de seconde est montée sur son mobile  de façon qu'elle puisse se mouvoir par rapport        < iii    rouage (le la. montre.  



  Dès qu'on cesse d'agir sur la. tige de remon  toir, le     cliquet    2 reprend sa position de repos;  le marteau 5 est soulevé sous l'action d'un  ressort. (non représenté), et l'aiguille de  seconde se remet. en marche.



  Center seconds watch. The present invention relates to a central seconds watch.



  The appended drawing represents, by way of example, one embodiment of the object (the invention.



  The single fi, ure is a plan view, only the elements necessary for understanding the invention being shown.



  The ratchet. barrel is designated by the number 1 and rotates in the direction of arrow A when winding the movement. The pawl 2 of the barrel ratchet carries a pin 3 acting, loris of the winding of the movement, against a cam 4 integral with a hammer 5 for resetting. Hammer 5 swivels at 6.



  In the rest position of the mechanism, shown in solid lines, the heart 7, carrying the second hand, can rotate freely, driven by the watch wheel.



  If the movement is wound up, the pawl 2 assumes the position shown in phantom lines; the. pin 3 actuates the cam 4 and, consequently, the hammer 5 comes to rest on the heart 7 and brings the second hand back to zero. The second hand is mounted on its mobile so that it can move in relation to the cog (the watch.



  As soon as we stop acting on the. winding rod, the pawl 2 returns to its rest position; the hammer 5 is lifted under the action of a spring. (not shown), and the second hand returns. working.

Claims (1)

REVENDICATION: Montre à seconde au centre, caractérisée en ce que le cliquet du rochet de barillet porte une goupille agissant, lors du remontage du mouvement, contre une came solidaire d'un marteau de remise à zéro, de sorte que l'aiguille de seconde peut être ramenée à zéro par rotation de la tige de remontoir. CLAIM: Central seconds watch, characterized in that the pawl of the barrel ratchet carries a pin acting, when the movement is being wound up, against a cam integral with a reset hammer, so that the second hand can be reset to zero by rotating the winding stem.
