Description
Balancier de montre. L'objet de la présente invention est un ba lancier de montre.
Ce balancier est caractérisé par le fait qu'il comporte au moins une paire de masse- lottes diamétralement opposées et. distinctes de la serge, à laquelle elles sont reliées par des moyens permettant de les déplacer ra- dialement, dans .le but,de modifier le moment d'inertie du balancier.
L'unique figure @du -dessin annexé montre une forme d'exécution de l'objet de l'inven tion, donnée à titre d'exemple.
Elle représente un balancier, dont 1 est le pivot et 2 la serge.
Celle@ci :porte deux vis radiales 3 et 4, .dia métralement opposées, et dont l'extrémité tournée vers le pivot est cylindrique et tra verse une masselotte 5, respectivement 6.
Dans l'axe de la vis, chaque masselotte est emprisonnée sans ébat entre l'épaulement de la vis en délimitant la partie filetée, et une bague 7, respectivement 8, chassée sur l'ex trémité cylindrique faisant suite au filetage.
Des paires de goupilles 9, 10, respective ment 11, 12, chassées dans la serge, guident. les masselottes dans le déplacement radial que le vissage ou le .dévissage -des vis 3 et. 4 peut leur faire effectuer, ces goupilles s'op posant à toute rotation des masselottes autour de l'axe des vis.
Il est clair que selon le sens de rotation iiiiprimé aux vis, on rapprochera ou éloignera ces dernières du pivot, simultanément avec les masselottes, faisant ainsi varier le mo ment d'inertie du balancier.
Les masselottes représentées sont. cour bées en ares de cercles de rayon tel qu'elles sont susceptibles de venir s'appliquer contre la face interne d e la serge à l'intérieur de la quelle elles sont disposées.
On pourrait également., au lieu de visser les vis dans la serge et de les laisser tourner folles dans les masselottes, procéder de ma nière inverse en les vissant .dans les masse- lottes, tandis qu'elles tourneraient folles dans . la serge.
Le guidage .des masselottes pourrait aussi être obtenu par d'autres moyens que deux goupilles pour chacune d'elles, par exemple par une rainure.
Il est enfin évident que les masselottes pourraient, de manière analogue, se trouver à l'extérieur -de la serge.
Watch balance. The object of the present invention is a watch maker.
This balance is characterized by the fact that it comprises at least one pair of diametrically opposed mass-burbot and. separate from the rim, to which they are connected by means allowing them to be moved radically, with the aim of modifying the moment of inertia of the balance.
The single figure of the appended drawing shows an embodiment of the subject of the invention, given by way of example.
It represents a pendulum, of which 1 is the pivot and 2 the serge.
This one: carries two radial screws 3 and 4, diametrically opposed, and whose end facing the pivot is cylindrical and passes through a weight 5, respectively 6.
In the axis of the screw, each weight is trapped without beating between the shoulder of the screw delimiting the threaded part, and a ring 7, respectively 8, driven on the cylindrical end following the thread.
Pairs of pins 9, 10, respectively 11, 12, driven into the rim, guide. the weights in the radial movement that the screwing or unscrewing -screws 3 and. 4 can make them perform, these pins opposing any rotation of the weights around the axis of the screws.
It is clear that depending on the direction of rotation iiiiprimé to the screws, the latter will be brought closer to or away from the pivot, simultaneously with the weights, thus varying the moment of inertia of the balance.
The weights shown are. curved in ares of circles of radius such that they are likely to come to rest against the internal face of the serge within which they are arranged.
It is also possible, instead of screwing the screws into the rim and letting them turn crazy in the weights, proceed in the reverse way by screwing them in the mass-burts, while they would turn crazy in. the serge.
The guiding .des weights could also be obtained by means other than two pins for each of them, for example by a groove.
Finally, it is obvious that the weights could, in a similar manner, be located outside the serge.
