Definitions

  • the present invention relates to improvements made to the control of the back-and-forth movement of the frames of a device for training the crowd of a weaving loom, in particular an armor mechanism.
  • the present invention relates to such a control assembly which responds better than so far to the various requirements of the practice and which is among other things simple and robust construction while being able to operate at high speed thanks to its low inertia.
  • the chassis of the device according to the invention which is crossed by a shaft whose ends projecting beyond the chassis are each associated with the heads of two connecting rods by means of an eccentric, is characterized in that the feet of these connecting rods are articulated to the rod of a rocking lever in T whose branches are associated with pivoting one with a short lever and the other with a long lever also attached respectively to the upper frame and the lower frame.
  • Fig. 1 is an elevational view of an armor mechanism comprising application of the improvements according to the invention.
  • Fig. 2 schematically illustrates the various elements of the control assembly according to the invention.
  • FIG. 1 Illustrated in FIG. 1 is the chassis 1 of an armor mechanism resting on two supports 2 and 3 placed above a weaving loom which is not shown.
  • a shaft 4 suitably driven in synchronism with that of the loom passes right through the frame 1 and protrudes on each side thereof.
  • two eccentrics 5, 6 On the parts protruding on either side of the chassis, two eccentrics 5, 6 have been wedged on the shaft 4, each associated with the head of a connecting rod 7, respectively 8.
  • the foot of each connecting rod 7, 8 is respectively associated with the rod of a lever 9, 10, roughly affecting the shape of a T and which are both articulated around a transverse fixed shaft 11.
  • levers 9 and 10 are offset angularly with respect to each other, so that the branches 9 a and 10 a lie substantially in the same horizontal plane, so that levers 12, respectively 13 associated with said branches and which comprise the same length support one of the sides of the upper frame 14 of the chassis 1.
  • the branches 9 b and 10 b of the levers 9 and 10 lie substantially in the same horizontal plane, so that levers 15, 16, of the same length (greater than that of the levers 12, 13) which their are associated by one of their ends, are attached by their other end to the lower frame 17 of the chassis 1.
  • each lever 9, 10 is associated with a short lever 12, 13 and with a long lever 15, 16, respectively.
  • each lever has longitudinal slots not referenced in which are fixed end caps 18, 19, 21, 21 to which the levers 12, 13, 15 and 16 are articulated respectively.
  • the diagram in fig. 2 schematically shows the mounting of the control assembly according to the invention comprising two mechanisms such as that described with reference to FIG. 1 and each located on either side of the chassis.
