Description

  

  Pièce d'horlogerie à remontage     automatique    au moyen     d'une    masse oscillante.    L'objet de la. présente invention est une  pièce d'horlogerie à. remontage automatique  au moyen d'une masse oscillante, suivant la  revendication -du brevet principal. Cette pièce  et caractérisée en ce que le point     d'oscil.la-          lion    de la. masse se trouve hors de la zone       médiane    du mouvement.  



  Le dessin ci-annexé représente, à titre  d'exemple, différentes formes d'exécution de  l'objet -de la. présente invention.  



  La.     fig.    1 est une vue en plan de la. pre  mière forme d'exécution, et la     fig.    2 est une  coupe par     II-II    de     fig.    1. Chacune des       fig.    3 à 6     représente,    en plan et à plus  petite échelle, une forme d'exécution diffé  rente.  



  Dans la forme d'exécution des     fig.    1 et 2,       2()    est une platine débordante, -de forme géné  rale     rectangulaire;    21 représente le bloc des  ponts usuels et 22 est un pont spécial entre       lequel    et la. platine est     montée,        rotativement,     en 23, la masse oscillante 24 dont le pour  tour entoure     complètement    celui du bloc des  ponts.

   On voit que le point. 23 se trouve hors    de la zone médiane du mouvement, cette po  sition permet un remontage rapide. 25     rQpré-          sente    schématiquement le barillet et 26 est  un pont logé dans     une    ouverture 27, prati  quée dans le fond de la masse 2'4 en regard  du point d'oscillation 23. Sur la face interne  du fond de la masse est monté un cliquet mo  teur 28, engrenant dans un rochet 29 monté  sous le pont 26; le pignon     '30    de ce rochet  actionne la roue 31 dont le pignon 32 engrène  avec le rochet     33    du barillet; 34 est un cliquet  de retenue.  



  Dans     @la    forme d'exécution  &  la     fig.    3, la  disposition générale est la     même    que dans la  forme     d'exécution    précédente, mais le cliquet  moteur 35 est monté sur un bloc 36, qui peut       coulisser    dans une rainure 37, pratiquée dans  le fond de la masse et qui est maintenu en  place par un ressort 38; lorsque le     ressort.-          moteur    est remonté à fond, le cliquet 35 n'ac  tionne plus le rochet -et se déplace dans la  rainure 37 à l'encontre du ressort 36.  



  Dans la forme d'exécution de la     fig.    4, on  a prévu une bascule 39 qui     tourna    autour de      l'axe de la     première    roue 40 du train d'engre  nage allant au rochet de     barillet,    cette bas  cule porte un cliquet moteur 41 qui agit sur  la roue 40 et présente, en outre, une fourche  42 entre les bras de laquelle pénètre un  organe d'entraînement porté par la calotte,  organe pouvant     iêtre    soit une cheville rigide,  soit un ressort-lame qui cède et cesse d'en  traîner la     bascule    lorsque le     ressort-moteur     est remonté à fond.  



  Dans la forme     d'exécution    de la     fig.    5,  43 est une bascule montée     rotativement    en  44, sur le mouvement,     portant    le     cliquet    mo  teur 45 et présentant une fourche 46; entre  les bras de cette dernière pénètre un organe       d'entraînement    porté par la masse.  



  Dans la forme d'exécution de la     fig.    6,  47 est une     bascule    présentant     comme    le pré  cédente, une fourche entre les bras  &  laquelle  pénètre un organe     d'entraînement    porté par la  masse, cette bascule     porte    elle-même deux       cliquets    moteurs 48 agissant, alternativement,  sur la roue 49, aux     -deux    extrémités d'un  diamètre de celle-ci; cette roue, portée par le  pont 50, -est la première de l'engrenage allant  au barillet.



  Self-winding timepiece by means of an oscillating weight. The object of the. present invention is a timepiece. automatic winding by means of an oscillating weight, according to claim -du main patent. This piece is characterized in that the point of oscil.la- lion of the. mass is outside the mid-range of motion.



  The accompanying drawing shows, by way of example, different embodiments of the object of the. present invention.



  Fig. 1 is a plan view of the. first embodiment, and FIG. 2 is a section through II-II of FIG. 1. Each of fig. 3 to 6 represent, in plan and on a smaller scale, a different embodiment.



  In the embodiment of FIGS. 1 and 2, 2 () is an overhanging plate, of generally rectangular shape; 21 represents the block of the usual bridges and 22 is a special bridge between which and the. plate is mounted, rotatably, at 23, the oscillating mass 24, the circumference of which completely surrounds that of the bridge block.

   We see that the point. 23 is located outside the median zone of the movement, this position allows rapid winding. 25 shows schematically the barrel and 26 is a bridge housed in an opening 27, made in the bottom of the mass 2'4 facing the point of oscillation 23. On the internal face of the bottom of the mass is mounted a motor pawl 28, meshing with a ratchet 29 mounted under the bridge 26; the pinion 30 of this ratchet actuates the wheel 31, the pinion 32 of which meshes with the ratchet 33 of the barrel; 34 is a retaining pawl.



  In @the embodiment & fig. 3, the general arrangement is the same as in the previous embodiment, but the motor pawl 35 is mounted on a block 36, which can slide in a groove 37, made in the bottom of the mass and which is held in place by a spring 38; when the motor spring is fully wound up, the pawl 35 no longer actuates the ratchet -and moves in the groove 37 against the spring 36.



  In the embodiment of FIG. 4, a rocker 39 is provided which rotates around the axis of the first wheel 40 of the gear train going to the barrel ratchet, this rocker carries a motor pawl 41 which acts on the wheel 40 and has, in In addition, a fork 42 between the arms of which penetrates a drive member carried by the cap, member which can be either a rigid ankle, or a leaf spring which yields and stops dragging the rocker when the motor spring is fully reassembled.



  In the embodiment of FIG. 5, 43 is a rocker mounted rotatably at 44, on the movement, carrying the motor pawl 45 and having a fork 46; between the arms of the latter penetrates a drive member carried by the mass.



  In the embodiment of FIG. 6, 47 is a rocker having, like the preceding one, a fork between the arms & which penetrates a drive member carried by the mass, this rocker itself carries two motor pawls 48 acting, alternately, on the wheel 49, at the -two ends of a diameter thereof; this wheel, carried by the bridge 50, is the first of the gear going to the barrel.
