  -1 - This utility certificate concerns a connecting rod for the control of heald frames in

textile machines.

  In the continuous and intense search for improvement and simplification of

  textile machinery which the applicant is seeking

  it has been found that the connecting rods for the control of heald frames already known in various forms and

  achievements could have been advantageously simplified

  and improved by adopting a new type of recessed engagement between the ends of the

  soles of the same rods bearing the pivot for the

  appearance with the frames of the smooth. This commitment is

  carried out, according to this certificate, by training

  inside the pivot itself, protruding from one of the

  the, a slot groove and associating cor-

  corresponding to the other sole a rib projection

  to freely fit into that dwelling, a commitment

  between the projection and the pivot housing being real-

  readable during the correspondence of said groove and the rib by relative displacement, in the direction of the length of the connecting rod, of the bars which form it and which carry the soles, with a possibility of blocking

  between the two bars when matching the den-

  between the two mutually engaged rack-and-pinion

res.

  The invention is represented by the drawing

  attached, which gives a practical embodiment and o

  FIG. 1 is a disassembled view of the end

  mitt of the connecting rod according to the certificate, ready to be associated with a heald frame; - Figure 2 illustrates the connecting rod of Figure 1, the parts being mounted in a first position of mutual engagement between the housing and the projection of two-two end plates of the same rod;

  - Figure 3 is a side view of the biel-

  in the mounting position corresponding to the figure

  re 2; and Figures 4 and 5 are views corresponding to those of Figures 2 and 3 which illustrate the connecting rod of Figure 1, the parts being mounted in a second position of mutual engagement between the housing and the projection of the two end insoles. of the connecting rod

even.

  If we refer to the drawings, we see that the

  connecting rod according to the certificate has two sole plates

  tremité 1 and 2 carried by two bars 3 and 4 intended to engage one next to the other during the

  correspondence of the toothed racks 3 ', 4' which are

  present them on one side, in relative positions

  variables that can be made stable by

  the application of clamping brackets such as 5.

  The sole 1 carries, fixed at its end, the pivot 6 for attachment to the frames of the rails, by

  example via the element 7 shown schematically

  Figure 1. As can be seen, this pivot

  6 has an internal housing 8 o is hollowed a groove

peripheral age 9.

  The sole 2 carries meanwhile, fixed at its end and in correspondence with the pivot 6, a

  protrusion 10 which comprises a rib 11 of complementary shape

of the throat 9.

  When you want to mount the connecting rod according to

  certificate, the soles 1 and 2 are juxtaposed and

  seems the bars 3 and 4 as it is shown in the

  Figures 2 to 5, making the various elements

  these by the application of the clamp caliper 5. In the

  mounting the projection 10 is freely inserted into the

  8, a sufficient space being provided for this purpose, but is then engaged by its own rib 11 in the groove 9 of the housing 8, by the external part (FIGS. 2 and 3) or by the internal part (FIGS. and 5) according to the relative position chosen for the engagement between the teeth of the rack 3 'and the rack 4' of the

bars 3 and 4.

  With this arrangement, we obtain a very fast assembly of the joint that achieves the rod, and whose displacement can be obtained with great simplicity by releasing the interlocking made between the

  racks of the bars via vice 5.

  At the same time, the construction of the connecting rod is simple

  and economic, as it is required for this type of

posing.

Claims (1)

  Connecting rod for the control of heald frames   in textile machinery, of the type in which a cou-   full of soles (1, 2) being made by their ex-   tremities carries a connecting pin (6) for said frames, characterized in that, inside said pi-vot, projecting from one of the soles, is formed a   housing (8) with a peripheral groove (9), and in that the   gate sole in correspondence with said pivot and said housing hollowed therein a projection (10) with a peripheral rib which can fit freely into   said housing, an engagement between the projection and the   of the pivot being made during the correspondence of said rib and groove, relative displacement, in the direction of the length of the connecting rod, the bars which form it and which carry the soles, with possibility   between the two bars, when   of the rack toothings of these, by means of clamps.
