Definitions

  • the present invention relates to the dobbies of the rotary type for training the crowd on the looms.
  • This shaft is driven by an intermittent rotational movement and at each stop, that is to say every half-turn of the aforementioned shaft, the reading device must, at the level of each of the blades of the dobby (that is to say of the actuation assembly associated with each heald frame) and according to the design or weave to be obtained on the fabric being woven, securing the actuating element either with said shaft to control the oscillating part, either with the latter in order to operate its angular immobilization.
  • This selective joining is generally obtained using a movable coupling member in the form of a key or pawl, subjected to the action of two articulated levers arranged on either side of the shaft in order to actuate said movable member at the two stop positions thereof.
  • These two levers are generally coupled to a single rod capable of moving axially in one direction and in the other according to the command received from the reading device of the dobby, elastic return means ensuring the return of the movable member. , levers and the Jbiellette to a rest position.
  • the present invention intends to remedy, and this by arranging the pivoting control levers so that they exert a perfectly symmetrical action both on the movable coupling member for its operation for securing the shaft and the actuating element, only on the latter for its angular immobilization.
  • these levers individually actuated by the reading device at one of their ends, are associated with elastic means which tend to return their opposite end in the form of a beak radially towards the shaft.
  • This spout is intended to cooperate with a notch formed in the periphery of a side plate. ment secured to the actuating element in order to ensure the angular immobilization thereof and the corresponding oscillating part.
  • each lever and the notch of the lateral plate of the actuating element can be given a conical or flared profile which on the one hand ensures the perfectly precise centering of this plate and d 'on the other hand a tendency to eject this spout, the latter effect taking the place of safety in the event of incomplete engagement of the movable coupling member.
  • this member joined to its elastic return in the coupling position makes it possible to give its free end or finger and to each of the notches provided in the shaft or in the drive disc a profile suitable for avoiding any ejection component. Consequently and unlike conventional systems, there is no need to provide any particular means for locking the movable member in the coupling position.
  • the dobby considered comprises a main shaft 1 animated by an intermittent rotational movement with stopping every 180 °.
  • this shaft 1 receives, with the interposition of an intermediate bearing, an eccentric 2 laterally secured to a plate 3; the cylindrical periphery of the eccentric 2 is engaged, still with the interposition of an intermediate bearing, inside the open part 4a with a circular profile of an actuating rod 4.
  • the free end of this rod 4 is coupled, through a pivoting arm 5, to the pull lever 6 connected to the corresponding heald frame of the envisaged blade.
  • a drive disc 7 whose axial opening is provided crenellated so as to cooperate with the periphery, itself crenellated, of the shaft 1.
  • the periphery of this disc 7 is cut out of two radial notches 7a, diametrically opposite one another. These notches 7a are intended to selectively receive the terminal finger 8a of a pawl 8 articulated on an axis 9 secured to the lateral plate 3 of the eccentric 2; a spring 10 tends to permanently recall the finger 8a of the pawl 8 in the direction of the shaft 1.
  • this pawl 8 For the control of this pawl 8 there are provided two levers 11 carried at articulation by fixed axes 12 added in the casing of the dobby parallel to the main shaft 1 thereof. Each lever 11 has a square profile and is biased by a spring 13 so as to bear against a corresponding fixed stop 14. These two stops 14 thus define on each lever 11 an actuating tail lla and it is understood that the two tails, arranged in the same zone A, are capable of being controlled by pushers (shown diagrammatically in the form of arrows 15) of the dobby reading device.
  • This engagement which occurs concomitantly with one of the periodic stops of the shaft 1, operates the subsequent angular immobilization of the eccentric 2, so that the latter is retained at the stop when the shaft 1 is at new set in rotation.
  • the aforementioned engagement caused the pawl 8 to tilt by the action of the spout llb against the heel 8b; the finger 8a of the aforementioned pawl is thus extracted from the notch 7a in which it was engaged. This extraction has the effect of uncoupling the drive disc 7 from the eccentric 2.
  • the invention is capable of being applied with advantage to rotary dobbies in which the actuating elements consist of cams against the periphery of which are held in abutment with follower rollers carried by traction levers coupled to the heald frames.
  • the coupling members can, in the known manner, take the form of keys movable radially in housings made laterally in the eccentrics or the cams so as to be able to be operated by the terminal nozzles llb of the levers 11 when said spouts engage in the notches 3a.
