  MONTRE SE REMONTANT AUTOMATIQUEMENT. 



   L'invention a pour objet une montre se remontant automatique- ment et comportant un organe de commande, monté à rotation et   éqùipé   d'un côté de son axe de rotation avec un contrepoids et de l'autre avec un élé- ment de support en forme de secteur percé d'une fenêtre, et   sur,lequel   sont disposés deux cliquets comportant des axes de rotation excentrés radialement et dirigés en sens inverse d'un mécanisme de commande faisant partie du mé- canisme de remontage de la   montreo   
Les deux cliquets des montres se remontant automatiquement de ce type actuellement connues coopèrent avec une roue à rochet commune.

   Or, étant donné que deux cliquets se trouvent à des distances différentes de l'organe de commande précité, les amplitudes des courses des cliquets fai- sant tourner la roue à rochet pendant le mouvement d'oscillation de va-et- vient de l'organe de commande, sont différentes, de sorte que le mécanisme de remontage n'est pas remonté régulièrement. Il peut même arriver, lorsque l'amplitude de l'organe de commande est faible, que la roue à rochet ne tour- ne que sous l'action du cliquet le plus éloigné de l'axe de rotation et que l'autre cliquet ne fonctionne plus. Mais on désire disposer d'une montre se remontant automatiquement, dont le mécanisme de remontage se remonte régu.- lièrement par les deux cliquets, même en cas de faible amplitude d'oscilla- tion de l'organe de commande. 



   On arrive à ce résultat suivant l'invention dans les montres se remontant automatiquement de ce type, en disposant pour les deux cliquets deux roues à rochet sur le même axe et de diamètres différents, en faisant coopérer le cliquet le plus éloigné de l'axe de rotation de l'organe de com- mande avec la roue de plus grand diamètre et l'autre cliquet avec la roue à rochet de plus petit diamètre. 



   Sur le dessin ci-joint qui représente un exemple de réalisa- 

 <Desc/Clms Page number 2> 

 tion de l'invention ne comportant que les éléments nécessaires à sa compré- hension : 
La figure 1 représente le mécanisme de remontage d'une montre se remontant automatiquement et dont divers éléments ont été omis pour ren- dre la figure plus claire; les figures 2 et 3 représentent en élévation latérale et en coupe verticale un organe oscillant faisant partie de ce mécanisme de remon- tage. 



   Sur la figure 1 le boîtier d'une montre à remontage automati- que est désigné par 10. Le mécanisme de remontage de cette montre comporte un organe de commande 11 monté à rotation au centre de ce boîtier rond et com- portant d'un côté de son axe de rotation un contrepoids 11a en forme d'arc de cercle et de l'autre côté un élément de support llb en forme de secteur, percé d'une fenêtre. Cet élément de support comporte deux cliquets 12 et 13 chargés par des ressorts et dont les axes de rotation sont excentrés radiale- ment. Dans la fenêtre de l'élément de support llb sont disposées sur le même axe deux roues à rochets 14 et 15 de diamètres différents, qui, par l'inter- médiaire d'une transmission dentée non représentée font tourner le barillet du ressort du mécanisme de remontage également non représenté, de façon à re- monter le ressort moteur.

   Ainsi que l'indique la figure 1, le cliquet 12 plus éloigné de l'axe de rotation de l'organe de commande 11 que le cliquet 13 coopère avec la roue de plus grand diamètre 14 et le cliquet 13 coopère avec la roue de plus petit diamètre 15. Il en résulte qu'en admettant que les am- plitudes des oscillations de l'organe de commande 11 soient les mêmes, les deux roues à rochet tournent d'un même angle sous l'action des deux cliquets, en arrivant ainsi au résultat cherché précité. Il est facile de voir qu'étant donné que les deux cliquets sont disposés en sens inverse, les deux roues à rochet tournent toujours dans le même sens. 



   Le contrepoids lla de l'organe de commande lui-même consiste en un arc de cercle creux, fermé aux deux extrémités et contenant un métal de poids spécifique plus élevé, tel que le mercure, le plomb, etc..., que ce- lui du métal qui constitue l'arc de cercle tubulaire, figures 2 et 3. Pendant les mouvements d'oscillation de va-et-vient de l'organe de commande 11, dont l'amplitude est limitée du fait que les roues à rochet sont disposées dans la fenêtre de l'élément de support llb des cliquets, le contrepoids vient rencontrer deux ressorts de tampons 16, qui l'arrêtent élastiquement et le font rebondir.

  WATCH AUTOMATICALLY WINDING.



   The object of the invention is an automatically winding watch comprising a control member mounted for rotation and fitted on one side of its axis of rotation with a counterweight and on the other with a support element in the form of a counterweight. form of sector pierced with a window, and on which are arranged two pawls comprising radially eccentric axes of rotation and directed in the opposite direction of a control mechanism forming part of the watch winding mechanism
The two pawls of currently known self-winding watches of this type cooperate with a common ratchet wheel.

   Now, given that two pawls are located at different distances from the aforementioned control member, the amplitudes of the strokes of the pawls causing the ratchet wheel to turn during the back and forth oscillation movement of the pawl. control member, are different, so that the winding mechanism is not reassembled regularly. It may even happen, when the amplitude of the control member is small, that the ratchet wheel turns only under the action of the pawl furthest from the axis of rotation and that the other pawl does not. does not work anymore. However, it is desired to have an automatically winding watch, the winding mechanism of which is wound up regularly by the two pawls, even in the event of a low amplitude of oscillation of the control member.



   This result is achieved according to the invention in automatically winding watches of this type, by arranging for the two pawls two ratchet wheels on the same axis and of different diameters, by making the pawl furthest from the axis cooperate. rotation of the control unit with the larger diameter wheel and the other pawl with the smaller diameter ratchet wheel.



   On the attached drawing which represents an example of

 <Desc / Clms Page number 2>

 tion of the invention comprising only the elements necessary for its understanding:
FIG. 1 represents the winding mechanism of a watch winding automatically and various elements of which have been omitted to make the figure clearer; FIGS. 2 and 3 represent in side elevation and in vertical section an oscillating member forming part of this winding mechanism.



   In FIG. 1, the case of a self-winding watch is designated by 10. The winding mechanism of this watch comprises a control member 11 mounted for rotation in the center of this round case and comprising on one side of its axis of rotation a counterweight 11a in the form of an arc of a circle and on the other side a support element 11b in the form of a sector, pierced with a window. This support element comprises two pawls 12 and 13 loaded by springs and the axes of rotation of which are radially eccentric. In the window of the support element 11b are arranged on the same axis two ratchet wheels 14 and 15 of different diameters which, by means of a toothed transmission, not shown, rotate the barrel of the spring of the mechanism. winding mechanism also not shown, so as to reassemble the mainspring.

   As shown in Figure 1, the pawl 12 further from the axis of rotation of the control member 11 that the pawl 13 cooperates with the wheel of larger diameter 14 and the pawl 13 cooperates with the wheel more small diameter 15. It follows that, assuming that the amplitudes of the oscillations of the control member 11 are the same, the two ratchet wheels turn at the same angle under the action of the two pawls, on reaching thus to the aforementioned sought result. It is easy to see that since the two pawls are arranged in opposite directions, the two ratchet wheels always turn in the same direction.



   The counterweight 11a of the controller itself consists of a hollow circular arc, closed at both ends and containing a metal of higher specific weight, such as mercury, lead, etc., than this- it of the metal which constitutes the tubular arc of a circle, FIGS. 2 and 3. During the back-and-forth oscillation movements of the control member 11, the amplitude of which is limited because the ratchet wheels are arranged in the window of the support element llb of the pawls, the counterweight comes to meet two buffer springs 16, which stop it elastically and make it rebound.
