Description
Barillet de mouvement de montre Roskopf. L'une des particularités du mouvement de montre Roshopf consiste en ce que le ren voi de minuterie, qui actionne la chaussée. est ajusté sur le barillet et petit tourner à frottement gras sur un canon de ce dernier. En vue de l'obtention d'an tel ajustement du renvoi, les surfaces de rotation du renvoi ou du canon comportent généralement des par ties élastiques qui produisent le frottement requis.
L'objet de l'invention est un barillet de ce genre. Cependant il se distingue par la. manière particulière et avantageuse dont le renvoi de minuterie est ajusté sur le canon du tambour de barillet. Il cet effet le renvoi présente, en sa partie centrale; une collerette sectionnée à deux endroits diamétralement opposés et dont les segments épousent la sur face cylindrique du canon du tambour de barillet.
Le dessin ci-joint montre, à titre d'exem ple, une forme d'exécution de 1'objet de l'in vention.
La fig. 1- en est (tue vue en plan, tandis que la fig. 2 en est une section suivant la ligne :1-B de la fig. 1. Dans le dessin, a désigne le tambour de barillet: b en est le couvercle qui est serti dans le tambour et comporte le canon c et une goutte d concentrique par rapport à ce dernier. Les alésages e du tambour a et du canon c sont destinés à, recevoir l'arbre du barillet. Le renvoi de minuterie f est ajusté à frottement gras sur le canon c, légèrement conique, et s'appuie sur la goutte d.
Le ren voi est ajouré en g de manière qu'il présente, en sa partie centrale, une collerette h. section née en i < < deux endroits diamétralement opposés.
Les segments de la. collerette ainsi formés sont élastiques et extensibles, en sorte qu'ils sont écartés lorsqu'on ajuste le renvoi sur le canon et épousent. ensuite la surface de rota tion de ce dernier en produisant l'effet (le frottement voulu.
Roskopf watch movement barrel. One of the peculiarities of the Roshopf watch movement is that the timer transmission, which activates the roadway. is adjusted on the barrel and small turn with greasy friction on a barrel of the latter. In order to achieve such an adjustment of the return, the rotating surfaces of the return or the barrel generally have elastic parts which produce the required friction.
The object of the invention is a barrel of this kind. However it is distinguished by the. a particular and advantageous manner in which the timer return is adjusted on the barrel of the barrel drum. This effect the reference presents, in its central part; a flange cut at two diametrically opposed locations and the segments of which match the cylindrical surface of the barrel of the barrel drum.
The accompanying drawing shows, by way of example, one embodiment of the object of the invention.
Fig. 1- is (seen in plan, while fig. 2 is a section along the line: 1-B of fig. 1. In the drawing, a designates the barrel drum: b is the cover which is crimped in the drum and comprises the barrel c and a drop d concentric with the latter. The bores e of the drum a and of the barrel c are intended to, receive the shaft of the barrel. The timer return f is adjusted to greasy friction on the barrel c, slightly conical, and based on the drop d.
The return is perforated in g so that it has, in its central part, a collar h. section born in i <<two diametrically opposed places.
The segments of the. flange thus formed are elastic and stretchable, so that they are spread when the return is adjusted on the barrel and hug. then the surface of rotation of the latter producing the effect (the desired friction.
