Description

  

  Dispositif de mise au point     polir    instruments de précision, tels que       trusquin,        comparateur,        ete.       L'opération consistant, par exemple, à  tracer ou à contrôler un traçage de pré  cision au moyen du trusquin, exige de la  part de l'opérateur une grande délicatesse  dans le maniement du levier comportant la  pointe à tracer.  



  La présente invention facilite cette opé  ration, en ce sens qu'elle permet d'opérer  plus rapidement, tout en augmentant la pré  cision du travail, et consiste en un dispositif  de mise au point, caractérisé par un poussoir  que renferme le tube formant support de  l'instrument, l'une des extrémités dudit pous  soir comportant un dispositif de commande,  l'autre extrémité venant appuyer en un point  sur un levier comportant la pointe à tracer  ou l'amplificateur.  



  Le dessin ci-annexé, donné à titre d'exem  ple, représente une forme d'exécution de  l'objet de l'invention.  



  La     fig.    1 est une vue en coupe du tube  renfermant le dispositif de mise au point,  lequel comporte un amplificateur;    La     fig.    2 est une vue en élévation d'un       trusquin,    dont la tige transversale     renferme     le dispositif, objet de l'invention.  



  Dans un tube ou support 1 se trouve  guidé     axialement    un poussoir 2 au moyen  des douilles 3 et 4; cette dernière filetée in  térieurement est traversée par la vis 5 du  poussoir, laquelle est munie à son extrémité  d'un poulet 6. L'autre extrémité du poussoir  comporte une pointe 7, sur laquelle s'appuie,  sous l'action du ressort 8, le plan incliné 9  du levier 10 pivoté en 11, lequel comporte  le comparateur 12 ou la pointe sèche 13.  



  On comprendra, suivant cette disposition,  qu'en vissant ou en dévissant le poulet 6,  on provoquera le déplacement infinitésimal  du levier 10 autour de son axe, et cela avec  la plus grande aisance.



  Focusing device polishing precision instruments, such as gauge, dial gauge, ete. The operation consisting, for example, in tracing or controlling a precise tracing by means of the gauge, requires from the operator great delicacy in the handling of the lever comprising the scribing point.



  The present invention facilitates this operation, in that it allows to operate more quickly, while increasing the precision of the work, and consists of a focusing device, characterized by a pusher contained in the tube forming a support. of the instrument, one end of said pous evening comprising a control device, the other end pressing at a point on a lever comprising the scribe or the amplifier.



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



  Fig. 1 is a sectional view of the tube enclosing the focusing device, which includes an amplifier; Fig. 2 is an elevational view of a gauge, the transverse rod of which contains the device, object of the invention.



  In a tube or support 1 there is axially guided a pusher 2 by means of the sleeves 3 and 4; this last internally threaded is crossed by the screw 5 of the pusher, which is provided at its end with a chicken 6. The other end of the pusher has a point 7, on which rests, under the action of the spring 8 , the inclined plane 9 of the lever 10 pivoted at 11, which comprises the comparator 12 or the dry point 13.



  It will be understood, according to this arrangement, that by screwing or unscrewing the chicken 6, it will cause the infinitesimal displacement of the lever 10 around its axis, and that with the greatest ease.
