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.
