Description
<Desc/Clms Page number 1>
Montre à remontage par masse oscillante Le brevet principal a pour objet une montre à remontage par masse oscillante, comprenant un mécanisme commandé différentiellement par le barillet et par le rochet de remontage et actionnant un élément qui peut arrêter ou libérer le rouage du remontoir automatique, cet élément étant une pièce découpée dans une plaque en matière élastique et affectant la forme générale d'un U, le mécanisme susmentionné étant disposé entre les deux branches de ce U et l'une de celles-ci au moins, sous l'effet de ce mécanisme, pouvant être appliquée contre un élément du rouage susmentionné ou éloignée de celui-ci pour permettre le remontage ou l'arrêter.
La présente invention concerne un perfectionnement, caractérisé par une portée périphérique que présente ledit mécanisme et par un bras monté rota- tivement sur le rochet, bras qui est relié élastique- ment à celle des branches de la pièce en contact avec la roue de remontage et qui est terminé par un patin destiné à travailler avec la portée susmentionnée.
Son but est de permettre une liaison meilleure entre la roue de remontage et le rochet.
Le dessin ci-annexé montre, à titre d'exemple, une variante des formes d'exécution représentées au brevet principal ; l'unique figure du dessin en est une vue en plan.
Dans cette figure, 5 représente la roue dentée actionnée par la masse et 12 .le rochet die remontage sur lequel est fixé l'axe 13. 7 est l'arbre du tambour de barillet. 20 désigne la pièce d'accouplement qui remplace la pièce 15 des formes d'exécution du brevet principal ; son extrémité inférieure est fixée par les tenons 20a au rochet 12 et son extrémité supérieure se termine par deux branches élastiques 20b et 20c dont la première est reliée à la roue 5 par la saillie 20d alors que la seconde appuie sur le bras 21 monté rotativement en 2la sur le rochet 12.
Autour de l'axe 13 peut tourner librement la roue 22 équivalente à la roue 17 des formes d'exécution du brevet principal. Cette roue est munie de deux portées périphériques en arc de cercle 22a et 22b et de dents 22c dans lesquelles est engagé le doigt 23 fixé à l'arbre 7. La portée 22a est de plus grand rayon que celle de 22b.
Le bras rotatif 21 présente à son extrémité libre un patin 21 b.
Lors du remontage, ce patin appuie élastiquement sur la portée 22a et solidarise entre eux la roue 5 et le rochet 12. Lorsque le remontage est terminé, la roue 22 a été déplacée par le doigt 23 de façon que sa portée 22b vient en regard du patin 21b, ce qui rompt la liaison entre la roue et le rochet.

Watch with winding by oscillating weight The main patent relates to a watch with winding by oscillating weight, comprising a mechanism controlled differentially by the barrel and by the winding ratchet and actuating an element which can stop or release the cogwheel of the automatic winder, this element being a piece cut from a plate of elastic material and having the general shape of a U, the aforementioned mechanism being arranged between the two branches of this U and at least one of them, under the effect of this mechanism, which can be applied against an element of the aforementioned cog or moved away from it to allow winding or to stop it.
The present invention relates to an improvement, characterized by a peripheral bearing surface that the said mechanism has and by an arm mounted rotatably on the ratchet, which arm is elastically connected to that of the arms of the part in contact with the winding wheel and which is terminated by a pad intended to work with the aforementioned scope.
Its purpose is to allow a better connection between the winding wheel and the ratchet.
The accompanying drawing shows, by way of example, a variant of the embodiments shown in the main patent; the only figure in the drawing is a plan view.
In this figure, 5 represents the toothed wheel actuated by the mass and 12 .the ratchet die reassembly on which the axis 13 is fixed. 7 is the shaft of the barrel drum. 20 denotes the coupling part which replaces part 15 of the embodiments of the main patent; its lower end is fixed by the tenons 20a to the ratchet 12 and its upper end ends with two elastic branches 20b and 20c, the first of which is connected to the wheel 5 by the projection 20d while the second presses on the arm 21 mounted to rotate in 2la on the ratchet 12.
Around the axis 13 can freely rotate the wheel 22 equivalent to the wheel 17 of the embodiments of the main patent. This wheel is provided with two peripheral surfaces in an arc 22a and 22b and with teeth 22c in which the finger 23 fixed to the shaft 7 is engaged. The bearing 22a has a greater radius than that of 22b.
The rotary arm 21 has at its free end a pad 21 b.
During reassembly, this pad resiliently presses on the bearing 22a and secures the wheel 5 and the ratchet 12 between them. When the reassembly is completed, the wheel 22 has been moved by the finger 23 so that its bearing 22b comes opposite the pad 21b, which breaks the connection between the wheel and the ratchet.
