Definitions

  • the present invention concerns an improved joint for connecting the uprights and the cross members of heald frames for weaving looms, and its object is to guarantee easy removel, while using the loom, of the lateral uprights of said frames so as to insert the stitches, both manually and with automatic selvedge thread drafting machines.
  • the present invention provides this improved solution and concerns, more exactly, an improved joint for connecting uprights and cross members of heald frames for looms, of the type in which the cross members are applied to shaped plates projecting from the uprights by means of a U-shaped frame, characterized in that an arm of said U-shaped frame is pivoted on the remaining part of the frame and is allowed to oscillate only so as to move away from the other arm.
  • said first arm is a square arm mounted by way of a cylindrical hinge onto a square plate forming said remaining part of the frame, and said cylindrical hinge is formed on the external part of said square plate, more or less at the centre of the base of the U-shaped frame.
  • elastic means can be provided in said U-shaped frame to oppose the oscillation of said first arm in respect of the other arm.
  • Said elastic means suitably comprise a rubber pad interposed between the portion of the first arm close to the hinge and an extension of the square plate external to said arm.
  • the upright 1 of a heald frame (not shown in full) comprises, near its upper end, a shaped plate 2 projecting towards the inside of the heald frame.
  • Said plate - made, like the upright, of light metallic material, as aluminium or a suitable alloy - is formed at the top with a bulge 3, on the upper part of which there is a round space for housing a barrel-shaped insert 4 of hard material, as steel or like.
  • the cross member 5 of the heald frame carries in turn, riveted onto its end, a U-shaped frame 6 meant to be connected to the plate 2, as shown in figure 3 of the drawing.
  • the U-shaped frame 6 is formed (fig. 1) in two parts - obtained by die-casting - which comprise a stout stiff square plate 7 and a square arm 8, more slender than the plate 7 but equally stiff, an end of which is pivoted by means of a cylindrical hinge joint 9 onto the external part of the square plate 7, more or less at the centre of the base of the U-shaped frame 6.
  • the other end of the arm 8 has a thickening 10, shaped so as to house the bulge 3 of the plate 2 - as shown in figure 3 - when the U-shaped frame 6 engages with said plate to form the joint of the invention.
  • the cylindrical hinge 9 is obtained by forming a seat 11 on the square plate 7 and a transversal cylindrical body 12 into the arm 8.
  • said arm 8 can freely oscilla­te in 9 so as to move away from the opposite arm of the square plate 7, while it cannot move towards said arm beyond the position of parallelism shown in figures 2 and 3, as its central square portion meets with the suitably shaped end of the square plate 7.
  • the oscillation of the arm 8 away from the other arm is instead opposed by elastic means, consisting of a rubber pad 13 interposed between the portion of said arm 8 close to the hinge 9 and an extension 14 of the square plate 7, formed externally to the hinge 9 and to the arm 8 as a prolongation of the element delimiting the seat 11.
  • the joint is then locked by using, in a manner known per se, a fastening screw 15 which forces the thickening 10 of the arm 8 onto the plate 2.
