Description

Procede de fabrication dtun eine horaire dit "a 1i ue" pour cadran d'horlogerie, et eigne appligue obtenu par ce procede. La presente invention a pour objets un procede de fabrication d'un eigne horaire dit "applique" pour cadran d'horlogerie et un eigne applique obtenu par ce procede. Process for the manufacture of an eine timepiece called "a 1i ue" for a watch dial, and applied sign obtained by this process. The present invention has for objects a process for the manufacture of a timepiece gem called an "applique" for a dial. watchmaking and an applied sign obtained by this process.

Parmi les differente modes de fixation de ei- gnes appliques sur une plaque d'un cadran d'horlogerie, la fixation au moyen de pieds est l'une des plus usuel- les. Ltobtention de ces pieds pose un probleme souvent delicat t Ils peuvent etre par exemple formes de tiges rapportees dans 1e eigne ou etre venus dtune piece avec celui-ci. Dans ce cas, an a propose d'obtenir ces pieds par decolletage. Neanmoins, du fait que 1e diam4tre de ces pieds est de Vordre de 5/10 de mm., les procedes susmentionnes presentent certaines difficultes et neces- sitent un soin tout particulier qui les rend relative- ment coüteux. Among the different methods of fixing ei- gnes applied to a plate of a watch dial, the attachment to the middle of feet is one of the most common them. > Obtaining de these feet poses an often delicate problem t eigne or have come from a room with this one. In this case, an a offers to get these feet by decolletage. Nevertheless, du causes the diameter of these feet to be about 5/10 of a mm., the above-mentioned methods present certain difficulties and require special care which makes them relatively- expensive.

Le but de la presente Invention est de fournir un procede pour 1'obtention des pieds de fixation de ei- gnes qui permet de realiser des pieds aux dimensions re- quises sans toutefois presenter de ce fait des difficul- tes particuli@res. The object of the present Invention is to provide a method for obtaining the feet of fixing of ei- gnes which allows to produce legs of the required dimensions without presenting de this causes particular difficulties.

Le procede suivant 1'invention est caracterise par 1e fait qu'on menage une saillie ä la base du eigne, pratique au moins une creusure dans cette saillie de fa- gon ä la rendre annulaire, puis supprime, par usinage, une partie de la mati@re de ladite saillie annulaire de fagon ä former des elements de cette saillie separes les uns des autres, constituant les pieds de fixation du eigne. The process according to the invention is characterized by the fact that a projection is provided at the base of the crown, practical at minus a hollow in this protrusion so that to make it annular, then remove, by machining, a part of the material of the said annular projection of the way ä to form of elements of this protrusion separated from each other, constituting the feet of fixing of shank.

Le dessin represente, ä titre dtexemple, une forme d'execution d'un eigne horaire applique obtenu par la mise en oeuvre du present procede et illustre diffe- rentes phases de sa fabrication. The drawing represents, ä as an example, a form of execution of a sign applied schedule obtained by the implementation of the present process and illustrates different annuities phases of its manufacture.

La fig. 1 est une vue en elevation dune ebau- ehe de eigne horaire en forme de parallelepipede ä base cärree. La fig. 2 en est une vue en plan, de dessous. La fig. 3 est une vue analogue ä celle de la fig. 2, dans laquelle ltoperation finale de fraisage destinee ä produire les pieds de fixation du signe a ete schematiquement representee. The fig. 1 is a en elevation dune sketch eigne hourly shaped > parallelepiped ä square base. The fig. 2 in is a plan view, from below. The fig. 3 is a view similar ä to that of fig. 2, in which the final milling operation to ä produce the legs of the attachment of > sign a has been represented schematically.

La fig. 4 est une vue en plan de dessous du signe termine, et La fig. 5 est une vue en elevation du signe, avec coupe partielle suivant la ligne V-V de la fig. 4. Le signe horaire represente au dessin est desi- gne par 1. I1 a la forme generale dlun parallelepip@de ä base carree, dont la plus grande dimension est en bau- teure En vue de ltobtention des pieds de fixation du signe an menage, ä la base de celui-ci, par tournage ou decolletage, une saillie circulaire la, puis an perce dans celle-ci un trou central 2. La saillie la a alors la forme dtune couronne (fig. 2). The fig. 4 is a bottom plan view of the sign ends, and The fig . 5 is an elevation view of the sign, with partial section along the line V-V of fig. 4. The time sign represented in the drawing is designated by 1. It has the general form of a parallelepip@of ä square base, of which the largest dimension is in ba- tore In view of obtaining the feet of fixing the sign an household, at > base of this one, by turning or turning, a circular projection la, then an pierces in that here a central hole 2. The protrusion la has then the shape of a crown (fig. 2).

Les operations suivantes consistent ä fraiser une partie de la matiere de la couronne lagen deux pas- see paralleles representees schematiquement par les deux zones hachurees 3 de la fig. 3. Ces deux fraisages mordent chacun sur 1e trou central 2 de la saillie annulaire la et sont appliques sur deux parties diametralement oppo- Sees de celle-ci. Les parties de la saillie la hachurees dans la fig. 3 sont detruites par ces operations de frai- sage, de sorte qutil ne subsiste de cette saillie que les parties designees par 1b aux fig. 3 ä5, separees Rune de 1'autre. The following operations consist of milling part of the material of the crown lagin two passes parallel represented schematically by the two hatched areas 3 of fig. 3. These two millings each bite on the 1st central hole 2 of the annular projection the and are applied to two diametrically opposite parts of this one. The parts of the projection la hatched in la fig. 3 are destroyed by these milling operations, de so that it not remains of this projection that the parts designated by 1b in figs. 3 ä5, separated Rune from the other.

Ces deux parties 1b constituent les pieds de fixation du eigne applique 1 sur la plaque du cadran. Hien que ces pieds 1b aient la forme de segments de couronne, il sera possible de les engager dans des trous circulaires de la plaque de cadran, circonscrits ä ces segments de couronne, et de les y maintenir sofft par un forgage, sofft par un matage ou un rivage. These two parts 1b constitute the feet for fixing the applique 1 on the dial plate. Although these feet 1b have the shape of segments of crown, it will be possible to engage them in the circular holes of the dial plate, circumscribed ä these segments of the crown, and the y to maintain sofft by a forging, sofft by a matting or a shore.

Eri variante, la forme de 1a saillie pourra Betre autre que circulaire, de meme que son trou central dans 1e cas oü, par exemple, cette saillie serait obtenue par etampage. Alternatively, the shape of the projection may be other than circular, of even its central hole in the first case where, for example, this protrusion would be obtained by stamping.

Enfin, il est ä remarquer que 1e present proce- de peut s'appliquer ädes eignes de toutes formes et di- mensions. Finally, it should be ä noted that the present process can be applied to signs of all shapes and > dimensions.
