Description
Procédé de fabrication d'un balancier, et balancier fabriqué selon ce procédé. La présente invention a pour objet un procédé de fabrication d'un balancier. Ce procédé est caractérisé par le fait que, en vue du réglage de son rayon de giration, on pra tique sur la serge au moins une incision de manière à délimiter dans son corps au moins une masse rattachée à la serge par une par tie déformable de force, mais non par la force centrifuge.
L'invention a aussi pour objet un balan cier obtenu au moyen de ce procédé.
Le dessin représente, à titre d'exemple, en plan et schématiquement trois formes d'exécution du balancier suivant l'invention, et dont la serge porte des groupes d'incisions pratiquées symétriquement aux extrémités d'un même diamètre.
La fig. 1 est une vue d'ensemble de la première forme d'exécution et les fig. 21 et 3 représentent chacune un détail des deuxième et troisième formes d'exécution. Dans ces figures, 1 désigne un balancier dont 2 est la serge. Perpendiculairement à son plan sont pratiquées des incisions 3 et<B>1</B> (fi-.<B>1), 5</B> et 6 (fig. 2), et 7 et 8 (fig. $), délimitant dans la serge des masses 9, respectivement 10 et 11, rattachées chacune au corps de la serge par une partie rétrécie 12., 13 et 14.
La répartition, sur le pourtour de la serge, de ces incisions peut être quelconque ou, au contraire, équidistante.
Le réglage du rayon de giration du ba lancier de la fig. 1 se fait en agissant radia- lement, avec une brucelle, par exemple, sur les masses 9, disposées symétriquement sur le même diamètre, ce qui, grâce au fait que les parties rétrécies l'2 peuvent être dé formées à volonté, permet de rapprocher ou d'éloigner de l'axe du balancier les masses 9 sans devoir craindre que leur position change à moins d'une nouvelle intervention voulue du régleur.
Le réglage des autres formes d'exécution se fait de la même manière. Ce réglage mo difie le rayon de giration du balancier.
L'expérience montre que le balancier fa briqué selon ce procédé permet de réaliser des réglages de la marche d'une montre avec une précision et une sûreté remarquables.
Method for manufacturing a balance, and balance manufactured according to this process. The present invention relates to a method of manufacturing a balance. This method is characterized by the fact that, with a view to adjusting its radius of gyration, at least one incision is made on the rim so as to delimit in its body at least one mass attached to the rim by a deformable part of the rim. force, but not by centrifugal force.
The invention also relates to a balance obtained by means of this process.
The drawing represents, by way of example, in plan and schematically three embodiments of the balance according to the invention, and the rim of which bears groups of incisions made symmetrically at the ends of the same diameter.
Fig. 1 is an overall view of the first embodiment and FIGS. 21 and 3 each show a detail of the second and third embodiments. In these figures, 1 designates a balance of which 2 is the serge. Perpendicular to its plane are made incisions 3 and <B> 1 </B> (fi. <B> 1), 5 </B> and 6 (fig. 2), and 7 and 8 (fig. $) , delimiting in the rim of masses 9, respectively 10 and 11, each attached to the body of the rim by a narrowed part 12, 13 and 14.
The distribution, on the periphery of the serge, of these incisions can be any or, on the contrary, equidistant.
The adjustment of the radius of gyration of the beam in fig. 1 is done by acting radially, with a tweezer, for example, on the masses 9, arranged symmetrically on the same diameter, which, thanks to the fact that the narrowed parts l'2 can be deformed at will, makes it possible to bring the masses 9 closer to or away from the axis of the balance without having to fear that their position will change unless there is a further desired intervention by the adjuster.
The adjustment of the other embodiments is done in the same way. This adjustment modifies the radius of gyration of the balance.
Experience shows that the balance made according to this process makes it possible to adjust the rate of a watch with remarkable precision and safety.
