Description

  

  Procédé de fabrication d'une boite de montre-bracelet à cornes.    L'objet de la     présente    invention est un  procédé de fabrication d'une boîte -de     montre-          bracelet    à cornes. Ce procédé est caractérisé  en ce qu'on transforme, par étampage, deux       plaque.    en deux gouttières, ferme chaque        < -xtrémité    de chacune de ces     gouttière    par       une    plaque de recouvrement, puis fixe les  parsies médianes des gouttières dans deux       !évidements    opposés pratiqués dans une car  rure, les parties extrêmes de ces gouttières  formant cornes.  



       Les        fig.    1 à 6 (lu dessin représentent, à  divers états de leur fabrication, les pièces       d'unr-    boite -de montre obtenue au moyen du  procédé suivant l'invention.  



  Ce procédé peut être     mio    en     oeuvre    par       exemple    de la façon     suivante:     On part de deux plaques métalliques de  forme oblongue et on les transforme par  étampage en deux gouttières cintrées 1 dont  l'une est montrée en plan en     fig.    1, en élé  vation en     fig.    2, et en     perspective    en     fig.    3.  Puis,     aur        chaque    extrémité de chaque gout-         tière,    on soude une plaque de recouvrement       ?,    comme montré en perspective en     fig.    4.

    



  D'autre     part,    sur la périphérie d'une car  rure 3, ronde par exemple     (fig.    5), on pra  tique, par exemple par étampage,     -deux    évi  dements 4 ,diamétralement     opposés    et s'éten  dant sur toute la     hauteur    de la carrure.  



  Après quoi, on place les     parties        médianes     des deux gouttières 1 dans les évidements 4,  comme montré en     fig.    6, et on soude ces  parties médianes à la carrure; il suffit,     après,     de fixer à celle-ci le fond et la lunette usuels  pour avoir la     boîte    complète.



  Method of manufacturing a wristwatch case with horns. The object of the present invention is a method of manufacturing a wristwatch case with horns. This process is characterized in that two plates are transformed by stamping. in two gutters, closes each <-extreme of each of these gutters by a cover plate, then fixes the median parsies of the gutters in two opposed recesses made in a car rure, the end parts of these gutters forming horns.



       Figs. 1 to 6 (the drawing represent, in various states of their manufacture, the parts of a watch box obtained by means of the process according to the invention.



  This process can be implemented for example in the following way: One starts from two metal plates of oblong shape and they are transformed by stamping into two curved gutters 1, one of which is shown in plan in FIG. 1, in elevation in fig. 2, and in perspective in FIG. 3. Then, at each end of each gutter, a cover plate is welded ?, as shown in perspective in fig. 4.

    



  On the other hand, on the periphery of a car rure 3, round for example (fig. 5), is practiced, for example by stamping, -two recesses 4, diametrically opposed and extending over the entire height of the middle.



  After which, the middle parts of the two gutters 1 are placed in the recesses 4, as shown in FIG. 6, and these middle parts are welded to the middle; it suffices, afterwards, to fix the usual case back and bezel to it to have the complete case.
