Definitions

  • the present invention refers to the mechanical double armor armor in which the hooks taken by one of the two claw frames which move vertically in opposite directions to each other, are angularly offset around the axis of their rod so as to escape from the other frame without having to extend for this purpose the duration of what is called the press, that is to say of the phase during which said hooks are selectively pushed back by the corresponding needles.
  • the present invention aims to remedy this drawback.
  • a guide board is provided pierced with individual slots for the passage of said strips, the orientation of these slots being such that the strips are not subjected to any torque when the hook is in its lowered position rest.
  • the stopper 4 escapes the action of the stopper 8 so that the hook is not pushed by the needle 2.
  • fig. 2 and 3 we referenced 9 the rod of a hook. It carries at its upper end a first main spout 10 (fig. 2), then a little lower a second main spout 11, oriented in plan (fig. 3) at 90 ° from the previous one, then much lower still a retaining spout 12 disposed in plan along the bisector of the angle of the preceding spouts.
  • the lower end of the rod 9 is finally bent over itself in the form of an eyelet 13, which is incompletely closed in the embodiment shown, this eyelet being intended to be connected to the corresponding heald 14 (fig 1) in the way that will be explained later.
  • the main spouts 10 and 11 are intended to cooperate with the respective blades 15 of the upper claw frame 16, and 17 of the lower claw frame 18, these two frames coming and going vertically in opposite directions to each other.
  • the retaining spout it cooperates on its side with one of the blades 19 of the fixed frame of open pitch 20.
  • the bottom of the depression 22 is perforated with a circular opening 23 whose profile is inscribed inside that 22a of the inlet of the depression 22.
  • each hook On the eyelet 13 of each hook is also hung an elastic strip 24 (fig. 4) which passes through the opening 22 and at the lower end of which the corresponding beam 14 is fixed.
  • a guide board 25 (fig. 4) pierced with narrow slots 26 for the passage of said strips 24.
  • the slots 26 are oriented so that when a hook rests on the bottom of the depression 22 corresponding to the bottom plate 21, its strip 24 has no torsion.
  • the elastic strip 24 exerts on the eyelet 13 a return torque which tends to precisely bring the hook back to the angular position of FIG. 3 and which therefore contributes to ensuring this correct orientation of the latter at rest.
  • this lamella the reaction torque of which increases rapidly with the angle of torsion, opposes any exaggerated rotation of the rod 9 which could result in one of the main spouts being able to meet a blade intended for another hook (for example the blade located above the rod 9 in fig. 3).
  • the invention has therefore made it possible to produce a mechanism with orientable hooks in which the correct orientation of the hooks in the low or rest position is ensured in a certain manner despite vibrations, inertia effects and other parasitic actions, which allows to operate it at higher speeds than those reached so far, without the risk of seeing selection faults appear.
