Abstract

La présente invention a pour objet un mécanisme de chronographe comprenant une première roue solidaire d'un premier coeur, ainsi qu'un premier marteau coopérant avec ledit premier coeur. Ce mécanisme se distingue par le fait que le premier marteau est chassé sur un axe de pivotement pivoté librement entre deux ponts ou entre un pont et la platine du mouvement et dont chaque extrémité constitue un pivot qui est pivoté librement dans une pierre chassée dans un logement desdits ponts ou de la platine ; et par le fait que le premier marteau ainsi que les pierres dans lesquelles sont pivotés librement les pivots de l'axe de pivotement sont chassés respectivement sur l'axe de pivotement et dans les logements correspondants de manière à ce que l'horloger, au montage du mécanisme, puisse ajuster in situ la hauteur du premier marteau par rapport à son coeur respectif uniquement en modifiant la position axiale du premier marteau sur son axe de pivotement et en enfonçant desdites pierres dans leur logement.

Figure imgaf001
The present invention relates to a chronograph mechanism comprising a first integral wheel of a first core, and a first hammer cooperating with said first core. This mechanism is distinguished by the fact that the first hammer is driven on a pivot axis pivoted freely between two bridges or between a bridge and the plate of movement and each end of which constitutes a pivot which is pivoted freely in a stone driven into a housing said bridges or platinum; and in that the first hammer as well as the stones in which the pivots of the pivot axis are pivoted freely are driven respectively on the pivot axis and in the corresponding housings so that the watchmaker, on assembly of the mechanism, can adjust in situ the height of the first hammer relative to its respective core only by changing the axial position of the first hammer on its pivot axis and pushing said stones in their housing.
