Abstract

Le mécanisme de commande des dispositifs d'affichage d'heures et de minutes comprend une bascule (15) prenant appui, sous l'effet d'un ressort de rappel, par l'intermédiaire d'un cliquet (18), sur une came en colimaçon (12) située au centre du mouvement, et qui fait un tour par heure. La bascule (15) se soulève donc progressivement sous l'effet de la came (12) pour retomber, en une chute instantanée, une fois par heure. Lors de ces chutes instantanées de la bascule (15), un secteur denté (23) que présente celle-ci entraíne, par l'intermédiaire d'un train d'engrenage (24, 25, 26), un pignon central (27) portant l'aiguille des minutes. Ainsi, une fois par heure, celle-ci retourne instantanément dans sa position initiale, en un mouvement rétrograde. La bascule (15) porte un cliquet (30) coopérant, à chacune des chutes instantanées de la bascule, avec une roue en étoile à douze branches, pivotée au centre du mouvement, et qui porte un disque indicateur des heures, dont l'affichage est ainsi du type dit "sautant".

Figure 00000001
The control mechanism for the hour and minute display devices comprises a rocker (15) bearing, under the effect of a return spring, by means of a pawl (18), on a cam spiral staircase (12) located in the center of the movement, and which makes one revolution per hour. The rocker (15) therefore lifts gradually under the effect of the cam (12) to fall back, in an instant fall, once per hour. During these instantaneous falls of the rocker (15), a toothed sector (23) that presents it drives, by means of a gear train (24, 25, 26), a central pinion (27) carrying the minute hand. Thus, once an hour, it instantly returns to its initial position, in a retrograde movement. The rocker (15) carries a pawl (30) cooperating, at each instantaneous fall of the rocker, with a star wheel with twelve branches, pivoted in the center of the movement, and which carries an hour indicator disc, the display of which is thus of the type known as "jumping".
