Description

  

  Calotte de chronomètre de     marine.       Dans les chronomètres de marine, le re  montage s'opère en général en introduisant  à l'intérieur de l'instrument une clé indépen  dante de celui-ci après avoir découvert un  orifice contenant le carré de l'arbre du ba  rillet sur lequel la clé s'adapte. Le couvercle  qui ferme l'orifice en question ne peut pas  être qualifié d'étanche et son ouverture fré  quente permet aux buées, vapeurs et pous  sières, de pénétrer jusqu'aux rouages,     c    e qui  finit par avoir une     influence    néfaste sur la  marche du chronomètre.

   Le but que pour  suit la     présente    invention est de remédier       à,    ces inconvénients et, en outre, d'éviter en  core les chocs et fatigues illicites que l'opé  rateur pouvait faire subir aux organes de la  pièce d'horlogerie lorsqu'il introduisait,     la.     clé dans son     intérieur.     



  Il est montré au dessin ci-annexé une ca  lotte de chronomètre de marine, selon l'in  vention, et donnée à     titre    d'exemple.  



  a est la calotte; elle porte à son extrémité  supérieure un pas de vis sur lequel s'adapte  la lunette et, sur ses     parois,    à son extérieur,  deux supports b,     diamétralement    opposés, qui  lui     permettent    de tourner dans son cercle de    suspension. Le fond de la. calotte possède  un renfoncement c clans lequel sont logés la  plupart (les organes de remontage.

   Ceux-ci  comportent une douille     d    qui est ajustée,  d'une manière étanche, dans le fond de la       calotte,    douille sur laquelle est vissé l'an  neau     (Il    et, qui présente, du côté     du        mouve-          rnent.,        mie    entrée carrée pour     l'arlue    r du  barillet. Cette     douille    porte une denture     e     qui engrène avec une roue f tournant sur  un bossage     g    du fond.

   Contre cette roue est  disposé un couvercle     h.    excavé dont le     bord     prend dans une battue de la périphérie du  fond et qui est     maintenu    sur le bossage     g     par une plaque     1)    fixée à celui-ci par une vis.  La,     manette   <I>in</I> est. fixée au couvercle et à la.  roue f par des vis traversant sa face de base.

    Le mouvement     s'introduit    par le haut dans  la. calotte et vient reposer par sa platine sur  la, battue     h    (le ladite calotte; l'arbre du ba  rillet s'introduit sans autre dans la, douille d  et, lors (lu remontage, il est entraîné par la       manette    m, qui est placée dans le prolonge  ment de l'axe des aiguilles. La construction  décrite ne gène en rien le brisement com  plet de la fabrication de la pièce d'horlogerie.      Le mouvement peut. être fabriqué complète  ment pour lui et la calotte avec les organes  Cie remontage qui lui sont adaptés forment  également un tout bien distinct dont la fabri  cation est complètement indépendante de  celle des autres parties de la montre.  



  Gomme la. douille<I>cl</I> est ajustée de façon  étanche dans le fond du chronomètre, ni les  poussières ni les buées ne peuvent pénétrer  à l'intérieur de la calotte. En outre, dans la  forme d'exécution représentée, l'engrenage       qui    est constitué par la partie dentée de d et       par    la roue f est protégé d'une façon suf  fisamment efficace par le couvercle la.  Toutes les     irrégùlarités    de fonctionnement       qui    avaient leur source dans l'introduction  de la clé dans la pièce sont complètement       évitées    par l'emploi de la construction repré  sentée à titre d'exemple.



  Marine chronometer cap. In marine chronometers, re-assembly is generally carried out by inserting inside the instrument a key independent from it after having discovered an orifice containing the square of the shaft of the ball on which the key fits. The cover which closes the orifice in question cannot be qualified as airtight and its frequent opening allows mist, vapors and dust to penetrate to the cogs, which ends up having a harmful influence on the operation of the stopwatch.

   The aim of the present invention is to remedy these drawbacks and, in addition, to further avoid the illicit shocks and fatigue that the operator could subject to the components of the timepiece when he was inserting. ,     the. key in its interior.



  There is shown in the accompanying drawing a marine chronometer ca lotte, according to the invention, and given by way of example.



  a is the crown; it carries at its upper end a screw thread on which the telescope fits and, on its walls, on its exterior, two supports b, diametrically opposed, which allow it to rotate in its suspension circle. The bottom of the. cap has a recess c clans which are housed most (the winding components.

   These include a sleeve d which is fitted, in a sealed manner, in the bottom of the cap, the sleeve onto which the ring is screwed (II and, which presents, on the movement side, mie entry square for the arlue r of the barrel This bush carries a toothing e which meshes with a wheel f rotating on a boss g at the bottom.

   Against this wheel is placed a cover h. excavated whose edge takes in a battue of the periphery of the bottom and which is held on the boss g by a plate 1) fixed to it by a screw. The <I> in </I> controller is. attached to the cover and to the. wheel f by screws passing through its base face.

    The movement is introduced from above into the. cap and comes to rest by its plate on the, beaten h (the said cap; the shaft of the ball is introduced without further into the, sleeve d and, when (re-assembly, it is driven by the lever m, which is placed in the prolongation of the axis of the hands. The construction described in no way hinders the complete breaking of the manufacture of the timepiece. The movement can be manufactured completely for itself and the cap with Cie components. windings which are adapted to it also form a distinct whole, the manufacture of which is completely independent from that of the other parts of the watch.



  Erase it. <I> cl </I> socket is tightly fitted to the back of the chronometer, neither dust nor mist can penetrate inside the shell. In addition, in the embodiment shown, the gear which is constituted by the toothed part of d and by the wheel f is protected in a sufficiently effective manner by the cover la. All the operating irregularities which had their source in the introduction of the key into the room are completely avoided by the use of the construction shown by way of example.
