Description

Raquetterie de mouvement de montre. L'invention a pour objet une raquetterie de mouvement de montre qui se distingue dune raquetterie habituelle par sa construc- tion simplifiee, Aservant une place relative- ment grande ä la pierre de contrepivot qui peut etre montee de maniere ä ce qu'elle amortisse les chocs qui pourraient lui etre transmis par faxe du balancier. Watch movement racket. The subject of the invention is a watch movement mechanism which differs from a usual mechanism by its simplified construction, reserving a relatively large space for the counterpivot stone which can be mounted in such a way that it dampens the shocks that could be transmitted to it by fax from the pendulum.

Cette raquetterie comprend une raquette et un eldment fixe maintenant cette der niere nur 1e coq. Elle est car,act6risäe en ce que la raquette et 1'el6ment fixe comportent ehacun une Partie arrnulaire presentant un ajustement cylindrique, Parties qui sont em- boit6es l'une dann Pautre de manizre que celle de 1'element fixe recouvre celle de la raquette, la raquette comportant, dune Part, une tete portant les goupilles ou la cle de raquette et, d'autre Part, une flache de com- mande, 1'element fixe etant forme par un collier ä deux branches fixees nur 1e coq. This racket includes a racket and a fixed element holding this last nur 1st cock. It is characterized in that the racket and the fixed element each comprise a ring-shaped part having a cylindrical fit, Parts which are nested one inside the other in such a way that that of the fixed element covers that of the racket. , the racket comprising, on the one hand, a head carrying the pins or the racket key and, on the other hand, a control wedge, the fixed element being formed by a collar with two branches fixed to the cock.

Le dessin ei-joint montre, ä titre d'exem- ple, deux formen d'execution de Pobjet de 1'invention. The attached drawing shows, by way of example, two embodiments of the object of the invention.

La fig. 1 represente une Premiere forme d'execution, en coupe longitudinale, tandis que La fig. 2 en est une vue en plan ; La fig. 3 montre la seconde forme d'exe- cution, ä plus petite echelle et en plan ; La fig. 4 en est une coupe longitudinale. Dann 1e dessin (fig. 1 et 2), an distingue la planche 1 du coq, la raquette 2, 1'616merit 3 et la pierre 4 de eontrepivot. fig. 1 represents a first form of execution, in longitudinal section, while fig. 2 is a plan view; fig. 3 shows the second embodiment, on a smaller scale and in plan; fig. 4 is a longitudinal section. In the 1st drawing (figs. 1 and 2), an distinguishes board 1 from the rooster, racket 2, 1'616merit 3 and stone 4 from the pivot.

La raquette 2 comprend la tete 2', des tink ä porter les goupilles ou la cle de ra- quette, une Partie annulaire 2" formant un ajustement cylindrique et une flache de commande 5. The racket 2 comprises the head 2', tinks to carry the pins or the racket key, an annular part 2" forming a cylindrical adjustment and a control wane 5.

L'element fixe 3 est forme par un collier comprenant une Partie annulaire 3', corres- pondant ä la Partie annulaire V de la ra- quette, et deux branches 3". Les Parties annulaires 2" et 3' sont emboit6es l'une daus lautre par leer ajustement cylindrique, de maniere que 1e --ollier 3 re ,öuvre la Par tie 2", les brarielies 3" de ce dernier etant fixdes sur la plauehe du coq ä, 1'aide de deux vis 6. The fixed element 3 is formed by a collar comprising an annular part 3', corresponding to the annular part V of the racquet, and two branches 3". The annular parts 2" and 3' are fitted together. on the other by the cylindrical adjustment, so that the first --ollier 3 works the Part 2", the braces 3" of the latter being fixed on the plate of the cock ä, with the aid of two screws 6.

La pierre de contrepivot 4 est sertie daus la Partie aiinulair#e 3' et repoye sur la planche dir eoq; cependant, elle pourrait eti#e disposee librement dans 1'oirverture de la partiP 3', sous un rebord de cette derriiere. La raquette 2 est aiusi mairitenue entre la planche du coq et la Partie annulaire 3' du collier 3 et peut tourner ä frottement gras sur 1'ajustement cylindrique de cette der- niere. The counterpivot stone 4 is set in the aiinular part #e 3 'and repoye on the board dir eoq; however, it could be placed freely in the opening of part 3', under a rim of this back. The racket 2 is thus held between the board of the cock and the annular part 3' of the collar 3 and can turn with fatty friction on the cylindrical adjustment of the latter.

Les deux vis de fixation du collier 3 pourraient etre vissees indifferemment soit dans la planche du coq, soit Jans les bran- ches 3". The two fixing screws of the collar 3 could be screwed indifferently either in the board of the cock, or in the 3" branches.

La Partie annulaire 3' permet d'y mon- ter une pierre de contrepivot ' Pxceptionnel- leinent grande et partant fort decorative. The annular part 3' makes it possible to mount therein a counterpivot stone which is exceptionally large and therefore very decorative.

La forme d'execution suivant läs ssg..3 et 4 se distingue de. celle decrite ei-dessus, par un montage particulier de la pierre de contrepivot qui offre 1'avantage d'amortir dans une certaine mesure les chocs qui pourraient lui etre transmis par faxe du ba- lancier. A cet effet, la pierre 4 est logge librement, avec du jeu, dans la Partie annu- laire 3' du collier 3, sous (in rebord intd- rieur 7 de cette derniere. La pierre est main- tenue appuyse sur la planche du coq 1, ä 1'aide d'un ressort 8 en forme dune etoile ä quatre branches flexibles. Les-branches de ce ressort sont engagees ä 1'etat de flegion, sous le rebord 7, tandis qne 1e mi- lieu du ressort, perce d'un trou 9, s'appuie elastiquement sur le sommet de la face exterieure bombee de la pierre 4. De ce fait, la pierre de coritrepivot reagit elastiquement contre les poussees axiales du pivot corres- pondant de laxe du balancier et les amortit. The form of execution according to läs ssg..3 and 4 differs from. that described above, by a particular assembly of the counterpivot stone which offers the advantage of absorbing to a certain extent the shocks which could be transmitted to it by fax of the balance. To this end, the stone 4 is lodged freely, with play, in the annular part 3' of the collar 3, under (in the inner edge 7 of the latter. The stone is kept supported on the board of the cock 1, with the aid of a spring 8 in the form of a star with four flexible branches. pierced with a hole 9, rests elastically on the top of the curved outer face of the stone 4. As a result, the coritrepivot stone reacts elastically against the axial thrusts of the pivot corresponding to the axis of the balance wheel and dampens them. .
