Abstract

Le dispositif d'entraînement et de réglage d'un compteur instantané comprenant une came escargot (5) entraînée en rotation par un axe (6) qui porte une aiguille (7) coopérant avec une graduation et une roue (11) pour son entraînement; une bascule (3) de compteur, soumise à l'action d'un ressort de rappel, comportant un bec (4) prenant appui sur la périphérie de la came escargot (5) et un cliquet coopérant, sous l'action d'un ressort de cliquet (9), avec la denture en dent de loup d'une roue de compteur (1); se distingue en ce que la came escargot (5) est montée à frottement gras sur une première portée (14) de l'axe (6), que cette came escargot (5) présente une lumière (18) recevant un doigt (19) d'un excentrique (20). Cet excentrique est pivoté sur un support solidaire de l'axe (6); le tout étant agencé de telle manière qu'un déplacement angulaire de l'excentrique (20) provoque un déplacement angulaire de la came escargot (5) par rapport à l'axe (6).The device for driving and adjusting an instantaneous counter comprising a snail cam (5) driven in rotation by an axis (6) which carries a needle (7) cooperating with a graduation and a wheel (11) for its drive; a counter rocker (3), subjected to the action of a return spring, comprising a spout (4) bearing on the periphery of the snail cam (5) and a cooperating pawl, under the action of a ratchet spring (9) with the wolf teeth of a counter wheel (1); is distinguished in that the snail cam (5) is frictionally mounted on a first bearing (14) of the shaft (6), that snail cam (5) has a slot (18) receiving a finger (19) an eccentric (20). This eccentric is pivoted on a support secured to the axis (6); the whole being arranged in such a way that an angular displacement of the eccentric (20) causes an angular displacement of the snail cam (5) with respect to the axis (6).
