Description

1tlontr e-reveil, ä barillet unique. L'irivention se rapporte ä une montre- i-eveil, ä barillet unique, dans laquelle 1e res- sort inoteur unique commande, par une de ses extremites, 1e premier mobile du finissa.ge et, par son autre extremite, ä laquelle est. fixee une denture de remontage, 1e mecanisme de reveil. Dans les montres de ce genre, la Liaison de rette extremite avee ledit meca- nisme doit etre telle que ce dernier ne soit actionne que lörsque son marteau a ete libere, tandis que 1e remoritage du ressort inoteur peut s'effectuer ä tout instant. Ce resultat est obteriu, selon 1'irivention, par 1e moyen de deux roues dopt Tune, en relation d'en- grenage avec ladite denture de remöntage, est fixee ä un arbre sur lequel est montee (olle 1'autre roue comniandant 1e mecanisme de reveil, la Liaison entre res deux rories etant realisee par un pignon-coulant Porte par 1'arbre, solidaire en rotation de celui-ci, et presentant une denture ä dents de loup maintenue en Prise, par un ressort, av ec une denture portee par la roue folle, les dentures etant disposees de fagon que, Tors du remontage, la roue fixee ä 1'arbre peut tourner librement par rapport ä la rorie folle, mais quelle ne peut tourner, en sens inverse, sans entrainer rette derniere. 1tlontr e-alarm clock, single barrel. The invention relates to an alarm watch, with a single barrel, in which the single driving spring controls, by one of its ends, the first mobile of the finissa.ge and, by its other end, to which is . attached to a winding toothing, the alarm mechanism. In watches of this type, the connection of the end head with said mechanism must be such that the latter is actuated only when its hammer has been released, while the winding of the inner spring can take place at any instant. This result is obtained, according to the invention, by means of two wheels adopted one, in gear relation with said winding toothing, is fixed to a shaft on which is mounted (the other wheel controlling the mechanism clock, the connection between the two wheels being made by a sliding pinion Carried by the shaft, integral in rotation with the latter, and having a wolf-toothed toothing held in engagement, by a spring, with a toothing carried by the idler wheel, the teeth being arranged in such a way that, when winding, the wheel fixed to the shaft can rotate freely with respect to the idler gear, but it cannot rotate, in the opposite direction, without dragging the latter.

Le dessin ci-annexe represente, ä titre d'exemple, une forme d'execution dune montre- r6veil selon la preseiite invention. The attached drawing shows, by way of example, one form of execution of an alarm clock according to the preseiite invention.

La fig. 1 represente un plan de son calibre; la fig. 2 montre un detail ä plus grande erhelle. fig. 1 represents a plan of its caliber; fig. 2 shows a larger scale detail.

Le barillet 1 presente une denture 2 en- grenant sur 1e premier mobile du finissage g. A 1'arbre de barillet est fixee la roue de re- montage 3 sur laquelle agit 1e dernier mobile du mecanisme de remontage 4 engrenant lui- in6rrie avec la roue A. The barrel 1 has a toothing 2 meshing with the first mobile of the finishing g. Fixed to the barrel arbor is the winding wheel 3 on which the last mobile of the winding mechanism 4 acts, meshing itself internally with the wheel A.

Celle-ci est fixee ä Farbre P dispose entre 1e pont P du mecanisme de reveil et la Pla- tine, de facon ä pouvoir tourner sur lui-meme. Cet arbre presente rin carre sur lequel peut coulisser 1e pignon-coulant D presentant une denture ä dents de loup destinee ä cooperer avee une denture correspondante portee par la roue C. Celle-ei est montee folle sur P et This is fixed to the shaft P arranged between the bridge P of the alarm mechanism and the plate, so as to be able to turn on itself. This shaft has a square on which the sliding pinion D can slide, having a toothing with wolf teeth intended to cooperate with a corresponding toothing carried by the wheel C. This one is mounted loose on P and

commande la roue 5 destinee ä actionner 1e marteau 6 du reveil. Un ressort en h61ice H appuie par une extremite contre le Fond dune creusure pratiqrree Jans Je pignon-coularrt et par son autre extremite contre une bague, de Position reglable, E vissee sur Farbre I'. Ce ressort tend ä maintenir en engagement les deux dentures ä dents de loup. controls the wheel 5 intended to actuate the first hammer 6 of the clock. A helix spring H rests at one end against the bottom of a recess made in the pinion-coulart and at its other end against a ring, of adjustable position, screwed onto the shaft I'. This spring tends to keep the two wolf-toothed teeth engaged.

Lorsque 1'on effectue 1e remontage, Je mobile 4 entraine la roue 4 et Farbre I' dass un sens tel que 1e pignon-coulant, solidaire en rotation de cet arbre, glisse sur la den ture de la roue C. Par contre, 1'extr-emit6 du ressort moteur fixee ä la denture 3 tend, une fois ce ressort remonte, ä, faire tourner en sens contraire la roue A et aussi la roue C., ceci par l'intermediaire du pignon-coulant D dopt . la denture perietr-e alors darrs celle de C. Ce mouvement peut s'effectuer librement lorsque 1e marteau du reveil est libere. Il est ä remarquer qu'alors 1e ressort H tourne avec 1'arbre 11' et 1e pignon-coulant D, de faqon qu'il n 'exerce aucun effet de freivage sur ce dernier, ce qui ne serait pas 1e cas si ce ressort etait fixe et Porte sofft par 1e porrt P sofft par la Platine. When the first winding is carried out, the mobile 4 drives the wheel 4 and the shaft I' in a direction such that the first sliding pinion, integral in rotation with this shaft, slides on the toothing of the wheel C. On the other hand, 1 extr-emit6 of the mainspring fixed to the toothing 3 tends, once this spring rises, ä, to rotate the wheel A and also the wheel C in the opposite direction, this by means of the sliding pinion D dopt. the teeth perietr-e then darrs that of C. This movement can be carried out freely when the first hammer of the clock is released. It should be noted that then the spring H rotates with the shaft 11' and the sliding pinion D, so that it does not exert any braking effect. on the latter, which would not be the case if this spring were fixed and Door sofft by the 1st porrt P sofft by the Plate.

Claims

CLAIM Watch-alarm clock, with a single barrel, in which the single mainspring controls, by one of its ends, the first mobile of the finishing and, by its other end, to which is fixed a winding toothing, I winding mechanism, characterized by a wheel in gear relation with said winding teeth and fixed to a shaft on

which is mounted insanely a wheel controlling the 1st alarm mechanism, the connection between these two wheels being made by a sliding pinion Carried by the shaft, integral in rotation with celrri-ei, and prrsserrrt a wolf teeth toothing maintenrre in Engagement, by a spring, with a set of teeth carried by the idler wheel, the teeth being arranged so that, when twisted, the wheel fixed ä, the shaft can rotate freely with respect to ä, the idler wheel, but which cannot rotate, in the direction reverse. without involving the latter. SUB-CLAIMS 1 1V: lontr-e-r, awakening according to claim, characterized in that the first spring now in engagement I sliding pinion is a coil spring. 2 iVIontre-r-awakening according to sub-claim 1, character-isAe in that said spring ii, sausage surrounds the shaft and is supported by one end rrrit6 against the first sliding pinion and, by 1'autre extr-emite, against a part integral with the shaft, so that it rotates with the latter and, consequently, exerts no friction effect on the idler wheel when the latter is driven by the wheel fixed to the shaft. 3 11Tontr,e-alarm according to sub-claim 2, characterized in that the above-irrdic shaft is mounted @ under the 1st bridge of the alarm mechanism.
