Description

         

  Clé à tube.    La présente invention concerne une clé à  tube comprenant des mâchoires coopérant  pour le serrage d'un tube, dans laquelle le ser  rage de la mâchoire mobile est assuré par un  levier dont l'extrémité forme poignée, ledit  levier étant articulé sur une cage et agissant  par son extrémité sous ladite mâchoire mo  bile.  



  Sur le     dessin    annexé est représentée, à  titre d'exemple, une forme d'exécution de la  clé objet de l'invention.  



  Les     fig.    1 et 2 montrent une clé en élé  vation, respectivement en position de desser  rage et de serrage.  



  La     fig.    3 représente la cage en perspec  tive.  



  La     fig.        -I    montre, de profil, l'extrémité ar  ticulée du levier.  



  La clé se compose     d'une    mâchoire. 1 ré  glable, munie d'une queue filetée 2 introduite  dans le logement 3 de la cage 4.  



  Un écrou moleté 5, logé dans l'encastre  ment 6 de la cage, se visse sur la queue file  tée 2.  



  Une mâchoire mobile 7 est articulée entre  les flasques de la cage.  



  Le levier 8, dont l'extrémité forme       poignée,    est articulé en 9 entre les flasques  de la cage 1, il s'étend au-delà de cette     arti-          eulation    et son extrémité comporte un ta  lon 10 sur lequel repose la mâchoire mobile.    Pour utiliser la. clé, on règle     approxima          tiv        ement    son ouverture par l'entremise de  l'écrou moleté 5 et on engage le tube entre  les mâchoires de la clé.     3s     En actionnant la poignée dans le sens de  la flèche     F        (fig.    1 et 2), le talon 10 fait pres  sion sous la mâchoire mobile 7 et le serrage  s'effectue.  



  A la. fin de ce serrage, l'arrière du talon go  1.0 vient en contact avec les parties, supé  rieures 11 des flasques de la cage 4 et évite  l'écrasement du tube.



  Pipe wrench. The present invention relates to a pipe wrench comprising jaws cooperating for tightening a tube, in which the clamping of the movable jaw is provided by a lever, the end of which forms a handle, said lever being articulated on a cage and acting by its end under said mo bile jaw.



  The accompanying drawing is shown, by way of example, an embodiment of the key object of the invention.



  Figs. 1 and 2 show a key in elevation, respectively in the loosening and tightening position.



  Fig. 3 shows the cage in perspective.



  Fig. -I shows, in profile, the articulated end of the lever.



  The key consists of a jaw. 1 adjustable, fitted with a threaded shank 2 inserted into the housing 3 of the cage 4.



  A knurled nut 5, housed in the frame 6 of the cage, is screwed onto the threaded shank 2.



  A movable jaw 7 is articulated between the flanges of the cage.



  The lever 8, the end of which forms a handle, is articulated at 9 between the flanges of the cage 1, it extends beyond this articulation and its end comprises a tab 10 on which the movable jaw rests. To use the. key, its opening is approximately adjusted by means of the knurled nut 5 and the tube is engaged between the jaws of the key. 3s By actuating the handle in the direction of arrow F (fig. 1 and 2), the heel 10 presses under the movable jaw 7 and tightening takes place.



  To the. end of this tightening, the back of the heel go 1.0 comes into contact with the upper parts 11 of the flanges of the cage 4 and prevents crushing of the tube.
