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.
