Definitions

  • the present invention concerns improvements in adjustable devices of mechanisms transmitting the controls from a shedding machine to the heald frames of a loom.
  • a shedding machine (or weave machine) is apt to control the heald frames of a loom by way of linkages, the articulated head of which allows two adjustments: an adjustment of the head position along the control lever - fixed stroke rocking lever - of the shedding machine (to adjust the heald frame stroke), and an adjustment of the head length (to adjust the starting position of the heald frame stroke).
  • the object of the present invention is to supply an articulated head of the linkage for the control of the loom heald frames by a shedding machine, allowing to carry out independently the adjustment both of the heald frame stroke and of the starting position of said stroke, thereby evidently simplifying the operations involved and allowing the operators to save considerable time.
  • the present invention concerns an articulated head of the control linkage for the heald frames of looms, operating on the control lever of a shedding machine to carry out the adjustment both of the heald frame stroke and of the starting position of said stroke, characterized in that it essentially consists of a stiff long guide and of a drawer longitudinally sliding therein with precision, the guide and the drawer being provided with a recess and with wide slots to house transversally said control lever, and in that, to the drawer there are associated first wedge-shaped locking means cooperating with first wedge surfaces of the drawer to block the drawer itself on the control lever and second wedge-shaped locking means distinct from said first locking means, cooperating with second wedge surfaces of the drawers to block the drawer itself to the guide, screw means being interposed between the guide and the drawer to adjust the longitudinal position of this latter into said guide, said first and second wedge-shaped locking means being operated and released by distinct screw means one independently from the other, so as to carry out said two adjustments independently.
  • the first wedge-shaped locking means suitably comprise a pair of opposed wedges, partially inserted into the slots of the guide and of the drawer and connected by adjustable screw means, in engagement with inclined transversal surfaces of a solid part of the drawer and with the side of the control lever of the shedding machine.
  • the second wedge-shaped locking means in turn suitably comprise a wedge interposed between said guide and said drawer, in engagement with an inclined longitudinal surface of a solid part of the drawer, and screw means to move said wedge along said inclined surface.
  • said screw means interposed between the guide and the drawer, to adjust the longitudinal position of this latter into the guide suitably comprise a screw which screws into a block fixed to said guide and into a solid part of said drawer.
  • the shedding machine 1 causes a control lever 2 to oscillate by a fixed angle ⁇ .
  • a linkage 3 transmits to the heald frame 4 the controls of the lever 2, to which it is connected by an adjustable head 5, the eye 6 of which is hinged to the connecting rod 7 of the linkage 3.
  • the adjustable head 5 (see figs. 2 to 7) consists of a stiff long guide 8, ending into the eye 6, and of a drawer 9 longitudinally sliding with precision into the guide 8.
  • the guide 8 and the drawer 9 are both provided with an inner transversal wide recess, opening on the sides into two longitudinal opposite slots, 10 and 11 respectively, to house transversally the control lever 2.
  • the drawer 9 comprises a wide solid part 12, with two inclined transversal surfaces 13 in correspondence of its inner end and an inclined longitudinal surface 14 on one side.
  • the outer end of said solid part 12 carries two threaded holes 15 and 16.
  • the adjustable head 5 is completed by first wedge-shaped locking means to block the drawer 9 on the control lever 2, by second wedge-shaped locking means to block the drawer 9 to the guide 8, and by screw means 23, interposed between said guide and said drawer, to adjust the longitudinal position of this latter into the guide.
  • the first wedge-shaped locking means comprise a pair of opposed transversal wedges 19, which are partially inserted into the slots 10 and 11 of the guide 8 and of the drawer 9 so that their inclined side engages with the inclined transversal surfaces 13, and one of their non-inclined sides is apt to engage with the side of the control lever 2.
  • the wedges 19 are connected together - and thus apt to be drawn close and apart - by a screw 20, which can be operated externally of the head 5, on its side.
  • the second wedge-shaped locking means comprise a longitudinal wedge 21 interposed between the guide 8 and the drawer 9, an inclined side of which engages with the inclined longitudinal surface 14 of the solid part 12 of the drawer 9, and a non-inclined side of which engages with one of the inner sides of the guide 8.
  • a screw 22, inserted into the threaded hole 15 of the solid part 12 of the drawer 9 - and apt to be operated externally of the head 5, at its end opposite to the eye 6 - allows to move the wedge 21 longitudinally along said inclined surface 14.
  • the screw means interposed between the guide 8 and the drawer 9 - to adjust the longitudinal position of the drawer, allowing it to be inserted into said guide and be blocked therein - finally comprise a screw 23, which screws into the hole 18 of the block 17 fixed to the guide 8 and into the hole 16 of the solid part 12 of the drawer 9, and which can be operated externally of the head 5 at its end opposite to the eye 6, said screw 23 being close and to the side of the screw 22.
  • the two adjustments - of the heald frame stroke and of the starting position of said stroke - can be carried out in an easy and practical way, one independently from the other.
  • the blocking of the head 5 on the control lever 2 of the shedding machine is obtained by tightening the screw 20 which draws close the wedges 19 so as to force them between the side of the control lever 2 and the solid part 12 of the drawer 9, along the inclined surfaces 13 of said solid part 12.
  • the lever 2 is blocked to the drawer 9, onto whose bottom 9A said lever 2 bears with its side opposite to that engaged by the wedges 19. Since the drawer 9 is blocked to the guide 8 by the second wedge-shaped locking means, the head 5 remains blocked on the control lever 2 in the selected position.
  • the blocking of the drawer 9 into the guide 8 is obtained by tightening the screw 22: this in fact forces the wedge 21 between the inclined surface 14 of the solid part 12 of the drawer 9 and the inner side of the guide 8, blocking said drawer to said guide in the reciprocal position set by the degree of tightening of the screw 23 into the hole 16 of the solid part 12 and into the hole 18 of the block 17 fixed at the end of the guide 8.
