Description

  

  Pièce d'horlogerie.    La présente invention a pour objet une  pièce d'horlogerie dont le bâti comprend au  moins deux plaques maintenues à distance  l'une de l'autre par des piliers.  



  Cette pièce d'horlogerie est caractérisée  par le fait que l'un au moins desdits piliers  présente des     moyens    permettant de modifier,  à cet endroit, l'écartement des plaques, en       vue    de régler l'ébat en hauteur d'un mobile  pivotant dans le bâti, dans le voisinage de ce  pilier.  



  Le dessin annexé représente, à titre  d'exemple, une forme d'exécution de l'objet  de l'invention.  



  La     fig.    1 est une vue en plan d'un mouve  ment de pendulette.  



  La     fig.    2 est. une coupe suivant     II-II    de  la     fig.    1, à échelle agrandie, et  la     fig.    3 est une coupe, analogue à celle  de la     fig.    2, d'une variante.  



  La pièce d'horlogerie représentée com  prend une platine 1 à laquelle est fixée, au  moyen de     vis    2, une     trois    quarts platine 3. Les  vis 2 prennent dans des trous axiaux de pi  liers rivés sur     la    platine 1. Le coq 4 est fixé  sur la trois quarts platine 3 au moyen d'une  des vis 2 se vissant dans un pilier 5. Ce der  nier présente une portée amincie     5a    sur la  quelle s'ajuste la trois     quarts        platine    3 et le  coq 4, et au-dessous de laquelle est pratiqué  un filetage 6. Un écrou 7 se visse sur ce file  tage. Le coq 4 et la trois quarts platine 3 sont  pincés entre cet écrou 7 et la tête de la vis 2.

      En vissant plus ou moins l'écrou 7, on peut  ainsi modifier l'écartement entre la platine 1  et la trois quarts platine 3 et, partant, modi  fier l'écartement entre la platine 1 et le coq 4,  ce qui permet de régler l'ébat en hauteur du  balancier S.  



  La variante de la     fig.    3 permet d'atteindre  le même but. L'épaulement 9a du pilier 9 sert  de point d'appui à une rondelle élastique con  cave 10 pressant la trois quarts platine 3 et le  coq 4 contre-la tête de la vis 2.



  Timepiece. The present invention relates to a timepiece the frame of which comprises at least two plates held at a distance from one another by pillars.



  This timepiece is characterized by the fact that at least one of said pillars has means making it possible to modify, at this location, the spacing of the plates, with a view to adjusting the height of a mobile pivoting in the frame, in the vicinity of this pillar.



  The appended drawing represents, by way of example, an embodiment of the object of the invention.



  Fig. 1 is a plan view of a pendulum movement.



  Fig. 2 is. a section along II-II of FIG. 1, on an enlarged scale, and FIG. 3 is a section, similar to that of FIG. 2, of a variant.



  The timepiece shown com takes a plate 1 to which is fixed, by means of screws 2, a three-quarter plate 3. The screws 2 take in axial holes of pins riveted to the plate 1. The cock 4 is fixed on the three-quarter plate 3 by means of one of the screws 2 screwing into a pillar 5. This last has a thinned bearing 5a on which fits the three-quarter plate 3 and the cock 4, and below which is made a thread 6. A nut 7 is screwed on this thread tage. Cock 4 and three-quarter plate 3 are clamped between this nut 7 and the head of screw 2.

      By screwing the nut 7 more or less, it is thus possible to modify the distance between the plate 1 and the three-quarter plate 3 and, consequently, to modify the distance between the plate 1 and the cock 4, which makes it possible to adjust the swing in height of the balance S.



  The variant of FIG. 3 achieves the same goal. The shoulder 9a of the pillar 9 serves as a fulcrum for an elastic con cave washer 10 pressing the three-quarter plate 3 and the cock 4 against the head of the screw 2.

Claims

CLAIM: Timepiece, the frame of which comprises at least two plates kept at a distance from each other by pillars, characterized in that at least one of said pillars has means making it possible to modify this place,. the spacing of the plates, in order to adjust the height of a "pivot mobile in the frame, in the vicinity of this pillar. SUB-CLAIMS 1. Timepiece according to claim, characterized by the that said pillar is threaded over part of its length to receive an adjusting nut against which one of the frame plates is clamped by a screw taking in the axial hole of the pillar.

Timepiece according to claim, characterized in that the said pillar has a shoulder on which bears an elastic washer and in the fact that one of the plates of the frame is clamped against this washer by a screw taking in the axial hole of the pillar. 3. Timepiece according to claim, characterized by a bridge which is fixed to one of the plates of the frame by a screw taking clans the axial hole of said pillar, the mobile, whose height is adjustable, being rotated in this bridge. 4. Timepiece according to claim and sub-claim 3, characterized in that said bridge is. the rooster, the mobile being. the pendulum.
