Abstract

Un garde-temps mécanique du type balancier-spiral, comporte un ressort spiral (10), un balancier (20) et un mécanisme d'échappement (30) relié par un point d'attache (12) au ressort spiral et agencé pour entretenir une oscillation du balancier. Le mécanisme d'échappement (30) est relié au point d'attache (12) du ressort spiral par un châssis (40) pivoté autour de l'axe (A) du balancier. Une extrémité externe (12) du ressort spiral (10) est attachée à cette pièce transversale (40) à un endroit situé d'un côté de l'axe (A) de balancier. Le châssis (40) comporte deux branches s'étendant de part et d'autre de l'axe du balancier (20) et formant un plateau tournant dont l'axe de rotation est confondu avec l'axe d'oscillation du balancier (20). Le mécanisme d'échappement (30) est situé d'un autre côté de l'axe (A) de balancier et agit sur le châssis pivoté pour libérer sa rotation et ainsi faire tourner l'extrémité attachée (12) du ressort spiral.

Figure imgaf001
A mechanical timepiece of the sprung-balance type, comprises a spiral spring (10), a rocker (20) and an escapement mechanism (30) connected by an attachment point (12) to the spiral spring and arranged to maintain an oscillation of the pendulum. The exhaust mechanism (30) is connected to the point of attachment (12) of the spiral spring by a frame (40) pivoted about the axis (A) of the balance. An outer end (12) of the spiral spring (10) is attached to this cross member (40) at a location on one side of the balance shaft (A). The frame (40) comprises two branches extending on either side of the axis of the balance (20) and forming a rotating plate whose axis of rotation coincides with the axis of oscillation of the balance (20). ). The exhaust mechanism (30) is located on another side of the balance shaft (A) and acts on the pivoted frame to release its rotation and thereby rotate the attached end (12) of the spiral spring.
