Description

  

  Procédé pour la fabrication de boîtes de     montres    de forme et boîte fabriquée  selon ce procédé.    L'invention comprend un procédé pour la  fabrication de boîtes de montres de forme en  trois parties (carrure, fond, lunette) et une  boîte fabriquée selon ce procédé.  



  D'après ce dernier on prépare une ébauche  de carrure massive d'une seule pièce de forme,  on y pratique deux battues de forme, on  donne à la lunette et au fond une portée de  forme correspondant à celle des battues.  



  La boîte est     cai,actérisée    par le fait que  sa carrure massive, d'une seule pièce de  forme, présente deux battues de forme et sa  lunette et son fond deux portées de forme  logées dans ces battues.  



  Le dessin annexé représente, à titre  d'exemple, une boîte de forme de     montre-          bracelet,    à différentes phases de sa fabrication.  



  Les     fig.    1 et 2 sont un plan et une coupe  transversale (par la ligne     II-II    de la     fig.    1)  de la carrure de la boîte à une première  phase;  Les     fig.    3 et 4 sont un plan et une coupe  transversale (selon la ligne IV-IV de la       fig.    3) de la carrure     à,    une seconde phase;    La     fig.    5 est une vue intérieure du fond;  La     fig.    6 est une coupe axiale de la boîte    terminée.

    L'exemple d'exécution représenté à la  forme d'un octogone comportant quatre grands  côtés, rectilignes et curvilignes, ainsi que  quatre petits côtés curvilignes, intercalés entre  les premiers; elle se compose de-trois parties:  la carrure massive a, le fond b, la lunette c,  qui sera munie de la glace d; la carrure est  munie de deux côtés d'une paire de cornes e  portant des barrettes f sur lesquelles sera  disposé le bracelet non représenté.  



  Pour fabriquer la boite en question on  commence par sortir à l'étampe dans une  pièce de métal une ébauche de carrure mas  sive g     (fig.    1 et 2) qui a la forme octogonale  voulue et avec laquelle les     quatre    cornes e  sont venues de fabrication. On fraise ensuite  dans chacune des faces de cette ébauche une  battue     lt    ou<I>i</I>     (fig.    3 et 4) quia une section  transversale en demi-queue d'aronde et la  disposition voulue de forme, au lieu d'être  circulaire; un talon de carrure demeure entre      les deux battues.

   De leur côté la lunette c  et le fond présentent chacun une portée     j     ou     k    qui a la disposition correspondante de  forme, c'est-à-dire non circulaire, et qui est  destinée à se loger dans la battue     h.    ou i de  la carrure     cs.    Le fait, que les battues et les  portées sont de forme, présente des avantages  technique et décoratif.  



  La boîte peut aussi présenter des char  nières. Il va sans dire qu'elle peut être faite  en tinte matière or, argent, métal, etc., et  peut avoir les formes les plus variées; elle  peut ne pas être une boîte de montre-bracelet,  auquel cas les cornes e peuvent être sup  primées.



  Process for the manufacture of shaped watch cases and boxes manufactured according to this process. The invention comprises a method for the manufacture of three-part shaped watch cases (caseband, back, bezel) and a case manufactured according to this method.



  According to this last one prepares a blank of massive middle part of only one piece of form, one practices two beatings of form there, one gives to the bezel and to the bottom a bearing of form corresponding to that of the beatings.



  The case is cai, actérisé by the fact that its massive middle part, of a single shaped piece, has two shaped battues and its bezel and its back two shaped staves housed in these battues.



  The appended drawing represents, by way of example, a case in the form of a wristwatch, at different stages of its manufacture.



  Figs. 1 and 2 are a plane and a transverse section (by the line II-II of FIG. 1) of the caseband of the case in a first phase; Figs. 3 and 4 are a plane and a cross section (along line IV-IV of Fig. 3) of the middle part in a second phase; Fig. 5 is an interior view of the bottom; Fig. 6 is an axial section of the finished box.

    The example of execution represented in the form of an octagon comprising four long sides, rectilinear and curvilinear, as well as four short curvilinear sides, inserted between the first; it is made up of three parts: the solid case a, the back b, the bezel c, which will be fitted with the crystal d; the middle part is provided on two sides with a pair of lugs e carrying bars f on which the bracelet, not shown, will be placed.



  To manufacture the box in question, we start by stamping in a piece of metal a blank of solid middle case g (fig. 1 and 2) which has the desired octagonal shape and with which the four lugs e have been manufactured. . We then mill in each side of this blank a battue lt or <I> i </I> (fig. 3 and 4) which has a cross section in the form of a half dovetail and the desired shape, instead of 'be circular; a middle heel remains between the two battues.

   For their part, the bezel c and the back each have a bearing j or k which has the corresponding arrangement of shape, that is to say not circular, and which is intended to be housed in the battue h. or i of the middle cs. The fact that the battues and the staves are shaped has technical and decorative advantages.



  The box may also have hinges. It goes without saying that it can be made of gold, silver, metal, etc., and can have the most varied forms; it may not be a wristwatch case, in which case the lugs e may be deleted.
