Definitions

  • the present invention relates to dobbies and other mechanical devices for training the crowd on weaving machines, and it relates more particularly to the coupling of heald frames on cables or other transmission elements intended for their operation. See for example FR-A-1 346 954.
  • each of the operating cables a is generally moored to one of the oscillating draw levers b of the mechanism c , while the opposite end is connected, through a pivoting sector d , to a register of springs e suitable for bringing the heald frame corresponding f to the rest position after it has been positively displaced by said mechanism c .
  • the cable a returned by a lower detour pulley g , has a strand oriented substantially vertically along the amount of the frame f envisaged.
  • each heald frame f is suspended from its two lateral pivoting sectors by means of articulated links, but in other applications it is the amount of the frame which is fixed to the vetical strand of the cable a , without any articulation, as illustrated in fig. 1. It is to this latter mounting method that the present invention refers.
  • the present invention mainly intends to remedy, which consists, in the concept of an assembly using tenon-shaped and mortise-shaped members which are made integral one with the cable, the other uprights of the frame in order to face each other in the same plane oriented substantially vertically, to have recourse to members which are split parallel to the plane of the frame in order to provide, on either side of the cable, surfaces of contact between the tenons and the mortises for the transmission of forces.
  • reference 1 designates one of the two uprights of a conventional heald frame.
  • a fork 2 has been reported, the opening 2 a of which is oriented horizontally towards the outside of the frame.
  • This opening 2 has defined two superimposed branches, each branch being cut a vertical slot 2 b whose bottom has in section a semi-cylindrical profile.
  • this fork 2 constitutes a female member in the form of a mortise, suitable for accommodating in its opening 2 has a stud formed by the end 3 a of a male member 3, hollowed out of a vertical housing 3 b open to its two ends.
  • a jaw 4 and two pushers 5 connected to each other by a clamping screw 6; as best shown in fig. 4, the jaw 4 has, opposite a vertical support face 4 a with semi-cylindrical section, two opposite oblique facets 4 b which are intended to cooperate with a ramp 5 a provided on the side of each pusher 5.
  • One of the pushers 5 is hollowed out with a vertical bore 5b through which the screw 6 comes to cooperate with a similar vertical tapping 5b of the second pushbutton, so that the operation of this screw 6 ensures the bringing together of said pushers which thus tend to expel the jaw 4 horizontally inside the housing 3 b .
  • This housing 3b is crossed by a vertical rod 7 which, in the manner known per se in systems of the negative type for drawing heald frames, interrupts at the level of the coupling device the cable attached to one of the levers dobby or other similar mechanical, the ends of said rod 7 being crimped at both ends of the envisaged cable. It is understood that if this rod 7 is inserted between the bottom of the housing 3 b and the bearing face 4 a of the jaw 4, the operation of the screw 6 ensures the axial and lateral locking of said rod on the member in the form of pin 3, while allowing the precise adjustment of this member with respect to the opening of the fork 2.
  • this end 3 a engages narrowly inside the opening 2 a , practically without play.
  • the rod 7 is applied perfectly in the bottom of the slots 2 b which it crosses vertically, so that a precise and stable interlocking is obtained, in which the transmitted force passes substantially through the center of the contact surfaces, which contact surfaces, highlighted in FIG. 5 by shaded parts, are arranged on either side of the axis of the rod 7. This avoids any creation of tilting torque, so that one can dispense with a mutual fixing of organs 2 and 3 using screws or other separate parts, regardless of the amount of effort to develop for the vertical operation of the heald frame envisaged.
  • this member is made to have, opposite the end 3 a , a heel 3 c whose tail is engaged with reduced clearance inside the opening 8 has a vertical slide 8 with a U-section, fixed permanently against the structure of the loom on each of the sides of the heald frames thereof.
  • This slide 8 is positioned so as not to interfere with the mounting and dismounting of the heald frames on the rods 7, these operations being carried out by moving the cables which support said rods outwards, in the manner illustrated in FIG. 6 and 7.
  • these operations are simplified by the fact that they do not require any operation of a screw or any other fixing member at the level of each coupling device.
  • the device according to the invention makes it possible to reduce to a considerable extent the overhang existing between each of the uprights 1 of the heald frame and the axis of the cable which ensures the displacement thereof.
  • each transmission element is here formed, no longer by a cable, but by a rod 9 of polygonal section, the lower end of which is coupled by a link 10 to a return lever 11 which is itself connected by a link 12 to the other return lever 11 and by a connecting rod 13 to the corresponding mechanical swing lever.
  • Each rod 9 is therefore comparable to the rod 7 of the previous embodiments; its correct angular orientation is ensured by a vertical guide 14 which is fixed to the structure 15 of the loom by a mechanism which allows the recoil of said guide 14 and of the rod 9 with a view to assembly and separation operations of the male and female organs of the coupling device associated with each upright 1 of the envisaged frame.
