Description

  

  Montre étanche.    L'objet de la présente invention est une  montre étanche qui possède une bague filetée  vissée dans la carrure et au moyen de la  quelle une glace en matière incassable est  serrée contre la lunette.  



  Le dessin annexé représente, à titre  d'exemple, une forme d'exécution de la montre  selon l'invention. La figure est une coupe  partielle suivant un diamètre de la montre.  



  La carrure est désignée par a; elle est  venue de fabrication avec une lunette     al,     munie de nervures circulaires     a2    contre les  quelles vient s'appliquer le bord de la glace  incassable     b.    Dans un taraudage     a3    de la  carrure est vissée une bague filetée c au  moyen de laquelle on peut presser fortement  la glace contre la lunette.  



  Le mouvement â est monté dans un cercle       d'encageage    e ajusté lui-même dans un tour  nage cylindrique a4 de la carrure. Un ressort  circulaire f, en forme d'assiette sans fond  entaillée sur son pourtour, maintient le cercle       d'encageage    du     mouvement        d    contre la portée         a5.    Ce ressort prend appui contre le fond g  de la boite qui est vissé dans un taraudage       a'    de la carrure. Le fond g est muni d'une  fraisure circulaire contenant une bague h de  métal malléable qui rend le joint étanche.  



  Le montage du mouvement dans la boite  s'opère en introduisant     successivement,    dans  la carrure, les pièces dans l'ordre suivant  lequel elles ont été décrites. La glace b,  placée la     première,    sera pressée contre la  lunette     al    par la bague filetée c; la pression  exercée fera pénétrer la matière malléable  de la glace entre les nervures     a5    de la  lunette     a1,    assurant ainsi par un joint à  labyrinthe une parfaite étanchéité. On in  troduira ensuite le mouvement avec son  cercle     d'encageage,    puis le ressort f et  finalement le fond g de la boite.

   Celui-ci  ne pressant pas directement sur le cercle       d'encageage,    mais indirectement au moyen  du ressort f, son serrage jusqu'à étanchéité  parfaite ne sera pas influencé par des varia  tions dans l'épaisseur du cercle     d'encageage.  



  Waterproof watch. The object of the present invention is a waterproof watch which has a threaded ring screwed into the middle part and by means of which an unbreakable material crystal is clamped against the bezel.



  The appended drawing represents, by way of example, an embodiment of the watch according to the invention. The figure is a partial section along a diameter of the watch.



  The middle is designated by a; it comes from manufacture with a telescope al, provided with circular ribs a2 against which the edge of the unbreakable glass is applied b. A threaded ring c is screwed into a tapping a3 of the middle part by means of which the crystal can be strongly pressed against the bezel.



  The movement â is mounted in a casing circle e itself adjusted in a cylindrical turn a4 of the caseband. A circular spring f, in the form of a bottomless plate notched on its periphery, maintains the caging circle of the movement d against the bearing a5. This spring bears against the bottom g of the case which is screwed into a thread a 'of the middle part. The bottom g is provided with a circular countersink containing a ring h of malleable metal which seals the seal.



  The movement is assembled in the case by successively inserting the parts in the middle part in the order in which they have been described. The glass b, placed first, will be pressed against the bezel al by the threaded ring c; the pressure exerted will cause the malleable material of the glass to penetrate between the ribs a5 of the bezel a1, thus ensuring a perfect seal by a labyrinth seal. We then introduce the movement with its casing ring, then the spring f and finally the bottom g of the box.

   As the latter does not press directly on the casing ring, but indirectly by means of the spring f, its tightening to a perfect seal will not be influenced by variations in the thickness of the casing ring.
