Definitions

  • the present invention relates to heald frames associated with dobbies and other mechanics which on the looms ensure the formation of the crowd, and it relates more particularly to the connecting devices interposed between these frames and the control levers of said dobby or mechanical .
  • connection devices have been proposed arranged to ensure, in a practically automatic manner (that is to say using a single operation), hooking and unhooking of all the frames and levers.
  • Devices of this kind in particular that described in Swiss patent N ° 545871 filed on December 14, 1971 in the name of StaubIiAG, generally include a hook with lateral opening provided at the end of each of the levers and clean, by angular displacement of the latter , coming to engage on a locking rod fixed on the cross member of the frame in question, a retaining loaded member opposing any untimely release, while being liable to be eclipsed momentarily for the stall of the parts.
  • the invention mainly intends to remedy, which consists essentially in replacing the fixed locking rod with a rotating ring established with a regular polygonal profile with six or eight sides, and in providing in the opening of each hook of the seats arranged to cooperate with the polygonal profile of the ring which is thus held without play in said opening.
  • Fig. 1 is a cutaway side view showing the arrangement of one of the elements of a hanging device established in accordance with the invention, the parts being shown before hanging.
  • Fig. 2 is a vertical section of detail on a larger scale, substantially along the plane indicated in II-II in FIG. 1.
  • Fig. 3 reproduces fig. 1 after hanging.
  • the reference 1 designates the lower cross member of a conventional heald frame, cross member against which is fixed a horizontal bar 2 integral with two flanges 3 which extend vertically downwards. These two flanges 3 are joined in the vicinity of their lower part by a transverse axis 4 on which freely pivots a locking ring 5 whose periphery is established in a hexagonal profile.
  • FIG. 6 shows the upper end of one of the levers for the vertical control of heald frames.
  • the top of this lever 6 is in the form of a hook 7 open laterally in the direction of the ring 5; it should however be observed that the edge of the hook 7 which defines the opening 7 'thereof has four flat surfaces 7a, oriented at 60 ° from one another so as to correspond to the hexagonal profile of the ring 5.
  • the hook 7 is integral with a lateral heel 8 disposed in front of the opening 7 'and established at a reduced thickness compared to that of the hook; the upper edge of this taton 8 is arranged in the extension of the lower surface 7s of the opening 7 'of the hook 7, so as to constitute a ramp Sa, as will be better understood below.
  • the heel 8 carries a transverse axis 9 on the protruding ends of which the two flanges of an overlapping pawl 10 are associated with a return spring 11.
  • This spring permanently tends to tilt the pawl 10 in a senstel as its beak 1 Oa protrudes in front of the opening 7 'of the hook 7, and it will be noted that this spout 10a has an oblique bearing 10b.
  • the angular displacement of the loaded pawl 10 under the effect of the spring 11 is limited by an internal stop 10c.
  • each hook 7 comes to embrace the ring 5 which corresponds to it, the flat surfaces 7a coming to bear against four sides of the profile of said ring. This therefore fits perfectly into the opening 7 '.
  • each hook 7 between the two corresponding flanges 3 are advantageously cut from chamfers referenced 3b in FIG. 2, at the same time as the end of said hook is tapered at 7b.
  • This arrangement combined with the precise positioning of the hooks 7 ensured by the permanent engagement of the thinned heels 8 between the flanges 3, avoids any risk of untimely blocking of the arms 6 under the effect of a transverse offset.
  • the release of the levers 6 simply involves the operation of the pawls 10 by momentary lifting of their end opposite to the spout 1 Oa. As shown in broken lines in fig. 3, this lifting ensures the release of the rings 5, so that the hooks 7 can then slip off laterally by tilting, thus returning to the off-hook position illustrated in FIG. 1.
