Definitions

  • the improvements which are the subject of the present invention aim to remedy these drawbacks and to allow the production of a device for opening the step of the type in question, the movable hooks of which are retained by slides.
  • the crowd-forming device is provided with movable hooks having a T-shaped cross section each comprising on the one hand a heel which engages with play in a longitudinal slide constituted by a groove formed in each face of the dividing partitions, on the other hand a core which extends vertically inside each slide to carry at its upper end a stud and which is extended laterally to constitute a drive spout by a knife, and thirdly a pusher suitable for approaching the retaining blade its electromagnet at the end of travel of said hook before the corresponding top dead center.
  • the grooves formed in each face of the dividing partitions comprise an oblique ramp towards the outside, suitable for placing each movable hook corresponding to a determined position on the one hand relative to the end of the elastic blade provided for possibly retaining this hook, and on the other hand to the path of its knife.
  • Each ramp advantageously extends by a slope in the opposite direction so as to determine an edge against which rests each movable hook at its top dead center.
  • FIG. 1 Illustrated in fig. 1 one of the lifting systems of a warp thread of a device for training the crowd of a loom.
  • This system comprises two identical hooks 1 associated with each end of a funicular element such as a cord 2, each hook being raised and lowered alternately by means of two knives 3.
  • the cord 2 passes around a first pulley 4 d 'a lifting beam 5 comprising a second pulley 6 rotating in the same yoke 5a as that 4.
  • Around the pulley 6 passes an arch 7 whose end opposite to that which is connected to the corresponding beam is anchored at a fixed point 8a d 'one of the two vertical separating partitions 8 placed on either side of the hooks 1.
  • the upper part of the partition walls supports an electromagnet 9 on either side of which are arranged two vertical elastic blades 10 whose lower end 10a is bent in order to retain the corresponding hook 1.
  • each separating partition 8 is provided with two grooves 8b, so that after assembly of two separating partitions, these grooves determine two adjacent slides 11 (fig. 2).
  • each hook 1 affects in cross section the shape of a T, that is to say that it comprises a core 1 a and a heel 1 b whose dimensions are such that the core 1a passes between two separating partitions 8 without substantial play, while the heel 1b is engaged in each of the slides 11 of said separating partitions, as is more particularly illustrated in FIG. 2.
  • each hook 1 is guided vertically, this guide retaining the hook with play inside the slides.
  • each hook 1 is extended upwards by a bar 1 c which ends in a stud 1 d.
  • the core 1a also has a side beak 1 e by which it is raised and lowered by the corresponding knife 3.
  • the hook 1 comprises a rigid pusher 1f.
  • each groove 8b is provided with a ramp 8c oblique towards the outside, that is to say towards the knife 3.
  • This ramp is extended upwards by a slope 8d oriented in the opposite direction so that the latter and the ramp form an edge 8e against which the hook 1 rests at its top dead center, and which determines its transverse position relative to the curved end of the blade 10 and the path of its knife 3.
  • each separating partition 8 is provided with an oblong opening 8f intended for guiding the lifter 5.
  • This guiding is more particularly shown in FIG. 7 or it is observed that its yoke 5a is disposed in the opening 8f which constitutes a vertical guide of said lifter and its retention between two dividing partitions 8.
  • the hooks 1 are made of an appropriate plastic material and overmolded at each end of the cord 2.
  • an assembly thus produced or that a group of assemblies or module, can be oriented in any way, for example horizontally, owing to the fact that all the mobile elements are guided longitudinally with respect to the dividing partitions. .
