Description

Monvement de montre ancre ä seconde. Second anchor watch movement.

L'invention a pour objet un mouvement de montre ancre ä second.e, dopt 1e barillet conduit 1e pignon de la roue d'echappement par 1'intermediaire de trois, mobiles de finis sage comprenant chacun un pignon et une roue. The subject of the invention is a second-hand anchor watch movement, in which the barrel drives the pinion of the escapement wheel by means of three moving wheels of wise finish, each comprising a pinion and a wheel.

Ce mouvement est caracterise en ce que sa roue moyenne engrene, dune Part, avec 1e pignon .de la roue dite des secondes et, d'autre pari, avec un pignorn de seconde augi liaire portant 1'aiguille de secondes, et dont 1e centre de rotation est situe sur Vage de symetrie midi-6 heures, lesdits mobiles etant disposes de maniere que la. roue moyenne passe sous 1'un des deug bras de 1'ancre. Ce bras peut etre, par egemple, sous 1e bras de sortie. This movement is characterized in that its middle wheel meshes, on the one hand, with the pinion of the so-called seconds wheel and, on the other hand, with an auxiliary second pinion carrying the seconds hand, and the center of which of rotation is located on Vage symmetry from noon to 6 o'clock, said mobiles being arranged so that the. middle wheel passes under one of the two arms of the anchor. This arm can be, for example, under the output arm.

Toutefois, cette roue moyenne pourrait passer ä la fois saus 1'un des brass de 1'ancre et sous la roue d'echappement. However, this middle wheel could pass both under one of the pallet arms and under the escapement wheel.

Cette derniere forme d'egecution du mou vement .suivant 1'invention est representee, ä titre d'exemple, au dessin annexe. This last form of execution of the movement according to the invention is shown, by way of example, in the appended drawing.

La fig. 1 en est une vue en plan, .cöte des ponts, tandis que la fig. 2, montre en elevation une partie caract6ristique des mobiles. fig. 1 is a plan view, side of the bridges, while FIG. 2, shows in elevation a characteristic part of the mobiles.

Le barillet 3- dun mouvement de muntre de forme :conduit 1e pignon 4 de 1a roue d'ancre 5, par 1'interm@ediaire d'un rouage habituel comportaut trois mobiles de finis sage comprenant 1e pignon 6 et 1a roue 7 des minutes, 1e pignon 8 et 1a roue moyenne 9, 1e pignon 10, et la roue 11 dite des! secondes-. Barrel 3- of a shaped movement: drives first pinion 4 of anchor wheel 5, via a usual gear train, comprises three mobiles of wise finish comprising first pinion 6 and minute wheel 7 , the first pinion 8 and the middle wheel 9, the first pinion 10, and the so-called wheel 11! seconds-.

Dans, 1e .dess in, an distingue 1e rochet de barillet 12, 1e rochet de couronne 13, 1e ba lancier 14 et 1e bras de sortie 15 de 1'ancre cooperant avec 1a roue d'echappement 5. In the first drawing, one distinguishes the first barrel ratchet 12, the first crown ratchet 13, the first balance 14 and the first output arm 15 of the anchor cooperating with the escape wheel 5.

Le barillet 3 et 1e mobile des minutes 6, placs au milieu du bäti, :sont pivotes dans la platine 16, dune pari, et dans: le pont de barillet 17, d'autre pari. The barrel 3 and the first mobile of the minutes 6, placed in the middle of the frame, are pivoted in the plate 16, dune bet, and in: the barrel bridge 17, the other bet.

Le mobile moyen 8, 9, 1e mobile 10, 11 dit des secondes et 1a roue d'ancre 5 avec son pignon 4 sont pivotes dians la platine 16, dune Part, et un pont de finissage 18, d'autre Part. La raue moyenne 9 engrene aussi dans un pignon de seconde auxiliaire 19 dont 1e centre de rotation est situe sur 1e Brand axe de symetrie midi-6 heures du bäti. Ce pignon est pivote, dune Part, dans la Pla tine 16 et, d'autre Part, dans un pont 20; il tourne ä raison d'un tour en 60 secondes et Porte, sur son tigeron 21 une aiguille trotteuse 22. The middle mobile 8, 9, the first mobile 10, 11 said seconds and the escape wheel 5 with its pinion 4 are pivoted in the plate 16, on the one hand, and a finishing bridge 18, on the other hand. The middle wheel 9 also meshes in an auxiliary seconds pinion 19 whose first center of rotation is located on the first axis of symmetry 12 o'clock-6 o'clock of the frame. This pinion is pivoted, on the one hand, in the plate 16 and, on the other hand, in a bridge 20; it rotates at the rate of one revolution in 60 seconds and carries, on its shank 21, a second hand 22.

Les mobiles sont dispos,es de maniere que la. raue moyen.ne 9 passe saus 1e bras de sor- tie 15 de 1'ancre et saus la raue d'echappe- ment 5, disposition qui permet de concentrer 1e plus possible 1e rouage et les organes de 1'echappement sur 1a Partie Bauche du bäti, ä proximite du balancier 14, la raue des mi- nutes etant dispos6e au milieu du bäti. The mobiles are arranged, are so that the. middle wheel 9 passes under the exit arm 15 of the anchor and under the escapement wheel 5, an arrangement which makes it possible to concentrate the gear train and the escapement components as much as possible on the left part. of the frame, close to the balance wheel 14, the minute track being arranged in the middle of the frame.

Il est bien entendu que, Jans certains mouvements, la raue moyenne pa-ssera. saus 1e bras d'entree de 1'ancre au Heu de passer saus. 1e bras de sortie. Le bras de 1'ancre comprend egalement la levee, meme au ca.s öü celle-ci serait rapportee au bras. It is understood that, in certain movements, the average line will pass. save the entry arm of the anchor instead of passing. 1st output arm. The arm of the anchor also includes the lifting, even in the case where it would be reported to the arm.

L'invention offne ainsi la p@ossibilite de realiser un mouvement de muntre 'a seconde, de taut Petit formest, de n'importe quelle forme et de hauteur normale, possedant un barillet relativement Brand et haut, et par- tant relativement puissant. The invention thus offers the possibility of producing a second-to-second movement, of small form, of any shape and of normal height, having a relatively large and high barrel, and therefore relatively powerful.

Pour limiter ä 1'extreme la hauteur du mouvement, les pignons 10 et 19, de meme que la raue 9 pourraient etre disposes en Par tie dans des creusures de la Platine 16. To limit the height of the movement to the extreme, the pinions 10 and 19, as well as the wheel 9, could be arranged partly in the recesses of the Plate 16.
