This invention relates to an arrangement for guiding push rods for the control of healds in weaving looms and in particular multiple-shuttle weaving looms.
In a normal weaving loom, the various operations for the depositing of the weft threads, the movement of the shed and the compacting of the weft thread take place successively over the entire width of the fabric. To increase productivity, some looms efiect these operations simultaneously. These include, for example, circular multi-shuttle looms in which each of these operations reaches a predetermined point of its cycle at each instant. In such apparatus, whether circular or fiat, it is mostly necessary to control the healds by means of a number of push rods. These push rods slide with either a parallel or a radial motion in bearings under the effect of an internal mechanism, such as a cam. To ensure that the opening movements of the shed are sufficiently progressive and to facilitate construction, it is desirable on the one hand to increase the number of such push rods and on the other hand to form them with a circular section. It is then necessary to prevent the push rods from turning about their own axes when in their bearmgs.
The object of the present invention is to obviate the above disadvantage.
According to the present invention, an arrangement for guiding push rods for the control of healds in weaving looms, more particularly multiple shuttle weaving looms, is characterised in that it comprises a fork fixed on each push rod and bearing against an adjacent push rod so as to prevent the first from turning.
For a better understanding of the invention, and to show how it'may be carried into eifect, the same will now be described with reference to the accompanying drawings, in which:
Figure 1 is a plan view of one constructional form;
Figure 2 is a sectional elevation of the arrangement shown in Figure 1;
Figure 3 is a plan view of another constructional form;
Figure 4 is a sectional elevation of the arrangement shown in Figure 3, and
tion.
Referring to Figures 1 and 2, it will be seen that the push rod A fast with the fork B is guided by the sliding of the said fork on the push rod C, whereby it is prevented from turning. Similarly, the push rod C fast with the fork D is guided by the sliding of the said fork on the push rod A.
In Figures 3, 4 and 5, there is shown a method of guiding in which the push rods hear one against the other by stepped formation.
The fork may be secured to the push rods either by keys (Figures 2 and 5), which may then serve as abutments to limit the movement of the push rods, or by means of threaded heads and nuts inside a bore formed in the stems of the push rods so that the push rods can be freely lowered with respect to one another.
It will be apparent that the position of the forks must permit the longitudinal motion necessary in the operation of the push rods.
I claim:
1. In a weaving loom having a plurality of push rods arranged in adjacent spaced-apart relationship for controlling the healds of said loom, means for guiding said push rods, said means comprising a forked member having a shank portion secured to each push rod and having prongs extending across and bearing against opposite sides of an adjacent push rod, whereby the push rod to which the forked member is attached is prevented from turning.
2. In a weaving loom having a plurality of push rods arranged in adjacent spaced-apart relationship for controlling the healds of said loom, means for guiding said push rods, said means comprising a forked member having a shank portion secured to each push rod and having prongs extending across and bearing against opposite sides of an adjacent push rod, the forked member on each push rod being axially spacedapart from the forked member on the adjacent push rods and the forked members on all of said push rods being in stepped formation relatively to one another in passing across the push rods, whereby the push rod to which each forked member is attached is prevented from turning.
3. In a weaving loom having a plurality of push rods arranged in adjacent spaced-apart relationship for controlling the healds of said loom, means for guiding said push rods, said means comprising a forked member having a shank portion secured to each push rod and having prongs extending across and bearing against opposite sides of an adjacent push rod, said forked members being arranged in pairs with the prongs of the forked member of one push rod bearing against the adjacent push rod and the prongs of the forked member on said adjacent push rod bearing against said first-named push rod, whereby the push rod to which each forked member is attached is prevented from turning.
4. A weaving loom as defined in claim 1, wherein each push rod passes through a bore formed 4 in its associated forked member and is secured therein by removable securing means.
5. A weaving loom as defined in claim 1, wherein each push rod is formed with a transverse bore and the shank portion of each forked member is received in said bore and is secured therein.
