Description
Procédé de fixation d'un mouvement de montre à remontage automatique. L'objet de la présente invention est un procédé de fixation d'un mouvement de mon tre à remontage automatique dans sa boîte, caractérisé en ce qu'on pratique sur le pour tour de l'entrée de cage de la carrure au moins deux trous cylindriques et qu'on place dans chacun (le ceux-ci une vis dont la tête fixe le filet de la platine du mouvement contre le bord de la carrure.
Quand la carrure est en métal dur, on peut chasser dans chacun desdits trous cylindri ques un canon taraudé de métal tendre et placer une desdites vis dans chacun de ces canons.
La difficulté de fixer un mouvement à remontage automatique sur la carrure pro vient de ce que le filet. de la platine est extrê mement mince; en effet, la. masse oscillante doit avoir le plus grand moment d'inertie pos sible pour un poids donné et s'étend par con séquent sur une grande hauteur par rapport au mouvement, ce qui laisse peu de place pour le filet de la platine.
Le dessin annexé représente, à titre d'exemple, un mouvement fixé au moyen du procédé selon l'invention. II n'est montré que ce que la compréhension de l'invention exige.
La fig. 1 est. une coupe montrant le mou- vement fixé dans la. carrure.
La -Fig. 2 est. une vue en plan d'une partie de la carrure, avant la. fixation du mouve ment.
1 représente le mouvement d'une montre à remontage automatique à. fixer, 2 la carrure de la boîte, supposée en métal dur. Sur le pourtour de l'entrée de eage se trouvent deux trous cylindriques dans lesquels sont chassés des canons .1 de métal tendre, tel que du lai ton. Au centre de ces canons 4 sont pratiqués des taraudages 5 dans lesquels pénètrent des vis 3. Ainsi, la platine 6 du mouvement se trouve solidement fixée à la carrure 2.
Method of fixing a self-winding watch movement. The object of the present invention is a method for fixing a self-winding watch movement in its case, characterized in that at least two holes are made on the circumference of the cage entry of the middle part. cylindrical and that we place in each (the latter a screw whose head fixes the thread of the movement plate against the edge of the caseband.
When the middle part is made of hard metal, it is possible to drive a threaded barrel of soft metal into each of said cylindrical holes and place one of said screws in each of these barrels.
The difficulty in fixing a self-winding movement on the pro caseband comes from the net. platinum is extremely thin; indeed, the. oscillating mass must have the greatest possible moment of inertia for a given weight and consequently extends over a great height in relation to the movement, which leaves little room for the thread of the plate.
The accompanying drawing represents, by way of example, a movement fixed by means of the method according to the invention. It is shown only what the understanding of the invention requires.
Fig. 1 is. a section showing the movement fixed in the. build.
The -Fig. 2 is. a plan view of part of the caseband, before the. fixation of the movement.
1 represents the movement of a self-winding watch at. fix, 2 the caseband, supposed to be in hard metal. Around the perimeter of the eage entrance are two cylindrical holes into which are driven .1 guns of soft metal, such as brass. In the center of these barrels 4 are formed threads 5 in which screws 3 penetrate. Thus, the plate 6 of the movement is securely fixed to the middle part 2.
