Description

  

  Dispositif d'assemblage à vis pour platine et pont, employé en horlogerie.    L'objet de la présente invention est un       .dispositif    d'assemblage à     vis    pour     platine     et pont, employé en horlogerie. La partie su  périeure -de la tige -de la vis est cylindrique  et     s'ajuste    à frottement dur dans les trous  rectifiés et     superposés    .du pont et -de la pla  tine, formant ainsi, à part une fixation du  pont sur la platine, un pied pour l'assemblage       exact,de        ces    pièces.  



  Au moyen de ce dispositif, il est possible  d'éviter les pieds généralement employés pour  l'ajustage des pièces en question. Ceci permet  une économie considérable en travail et en  outillage. Cette manière d'assemblage est  donc surtout favorable pour les mouvements  bon marché.  



       Le    dessin annexé montre, à titre d'exem  ple, une forme     d'exécution    -de l'objet de l'in  vention.  



  La figure unique est une vue en coupe  du dispositif     d'assemblage    à vis selon l'in  vention.    La tête     @de    la vis est désignée par a. Sa  tige est ,divisée en deux parties distinctes b  et c. La partie     supérieure    b est cylindrique et  lisse, tandis que la partie c est filetée.  



  Le pont d possède une     noyure    e pour la  tête a de .la vis et un trou rectifié f pour le  passage de sa tige. La platine y est percée  d'un trou dont la partie supérieure h corres  pond au trou f -du pont et dont la partie in  férieure i est taraudée et coopère avec la par  tie filetée c -de la tige.  



  On voit sans autre qu'en vissant ensemble  le pont et la platine au     moyen,de    la vis dé  crite, les     -deux    pièces seront exactement ajus  tées l'une par rapport à l'autre, la partie b  jouant le rôle de pied. Dans le     .dispositif    se  lon l'invention, une vis ordinaire de fixation  est donc combinée avec un pied d'ajustage et  présente les mêmes avantages que     ces    orga  nes séparément.



  Screw assembly device for plate and bridge, used in watchmaking. The object of the present invention is a screw assembly device for plate and bridge, used in watchmaking. The upper part - of the rod - of the screw is cylindrical and fits with hard friction in the rectified and superimposed holes of the bridge and - of the plate, thus forming, apart from a fixing of the bridge on the plate, a foot for the exact assembly of these parts.



  By means of this device, it is possible to avoid the feet generally used for adjusting the parts in question. This allows a considerable saving in labor and tools. This way of assembly is therefore especially favorable for inexpensive movements.



       The accompanying drawing shows, by way of example, an embodiment of the object of the invention.



  The single figure is a sectional view of the screw assembly device according to the invention. The head @of the screw is designated by a. Its stem is, divided into two distinct parts b and c. The upper part b is cylindrical and smooth, while the part c is threaded.



  The bridge d has a core e for the head a of the screw and a ground hole f for the passage of its rod. The plate is pierced there with a hole whose upper part h corresponds to the hole f -du bridge and whose lower part i is threaded and cooperates with the threaded part c -de the rod.



  It can be seen without further that by screwing together the bridge and the plate by means of the screw described, the -two parts will be exactly adjusted to one another, part b playing the role of a foot. In the .dispositif according to the invention, an ordinary fixing screw is therefore combined with an adjusting foot and has the same advantages as these organs separately.
