Definitions

  • the present invention relates to a mechanism for controlling the reciprocating movement of the claw frames of a device for forming the crowd of a loom.
  • the invention relates more particularly, although not exclusively, to a device of the type in question produced in the form of an armor mechanism having a great length in the direction of the chain.
  • Armor mechanics of this kind are generally actuated by means of a set of connecting rods and levers from a rotating shaft in synchronism with the loom.
  • This shaft which is arranged transversely, that is to say in the direction of the weft of the fabric, is located outside the chassis of the machine.
  • eccentrics or cams actuating levers intended to control rockers or similar devices from which the usual control levers for the two claw frames leave.
  • control shaft is located in the middle part of its chassis so that the rods controlled by this shaft are short and light, therefore economical, although very resistant to buckling.
  • the mechanism according to the invention comprises a shaft arranged in the middle part of the chassis of the device, while the V-shaped lever wedged on this shaft comprises two articulations for the ends of two short connecting rods whose opposite ends are respectively articulated in opposition to the two usual pendulums which control the actuation levers of the two claw frames.
  • the attached drawing given as an example, will allow a better understanding the invention, the characteristics which it presents and the advantages which it is capable of providing:
  • the single figure of the drawing is a schematic elevation view of the mechanism according to the invention.
  • the chassis 1 of an armor mechanism has been shown diagrammatically in broken lines, essentially comprising two claw frames 2, 3 which are moved vertically back and forth by means of a control mechanism according to the invention.
  • the frame 1 is placed on two beams 4, 5 located above a not shown weaving loom whose warp threads must be raised and / or lowered by means of the weaving mechanics illustrated.
  • the control shaft of the mechanism according to the invention is arranged in the middle part of the chassis 1 and it has been assigned the reference 6. This shaft is controlled in rotation by the loom and we will not return to this well known drive .
  • the lever 11 has an extension 11c in duquels angles are mounted two axes 13, 14 around which are articulated respectively at one end of a connecting rod 15, 16.
  • the frames 2 and 3 are driven in a vertical back and forth movement thanks to the presence of two long levers 17, 18 associated with the upper frame and by two short levers 19, 20 articulated to the lower frame 3.
  • the levers 17, 19 and 18, 20 are mounted oscillating in pairs on a balance 21, 22 which pivots around a shaft 23, 24. These two shafts are arranged symmetrically with respect to the transverse plane of the chassis 1 containing the geometric axis of the shaft 6.
  • each cheek 21 has , 22 a comprises a fixed axis 25, 26 around which the second end of the levers 15, 16 pivots.
  • the connecting rods 15 and 16 are relatively short, so that they do not interfere with rapid operation of the mechanics because they do not cause any difficulty in terms of of their inertia, even if the length of the chassis 1 in the direction of the chain is very large.
  • the ends of the levers 17, 18, 19, 20 which cooperate with the pendulums 21 and 22 can be placed in different positions in lights 21 b , 21 c of the pendulum 21 and 22 b , 22 c of that 22 in order to adjust the stroke of frames 2 and 3.
