Description
E. FROEHLJCH HEDDLE FOR HARNESS FRAMES Jan. 16, 1962 Filed Oct. 6, 1958 I71 van *0 r Ernst FraekZLcl United States Fatent Ufifiee 3,016,926 HEDDLE FUR HARNESS FRAMES Ernst Froehiich, Aibisweg 5, Rueschlilron, Zurich, Switzerland Filed Get. 6, 1958, Ser. No. 765,439 Claims priority, application Austria Oct. 7, 1957 2 Qlaims. (Q1. i39-93) The present invention relates to heddles for harness frames and refers in particular to a heddle having hookshaped ends for loom harness frames. Heddles of this type in stacks may he readily removed from the harness frames and mounted thereon with comparative ease, whereby, however, is experienced a serious drawback in that the stacks of heddles when detached fall apart, as the heddles are not interconnected.
The present invention aims to eliminate the abovementioned drawback and is essentially characterized in that the heddles at each of their two ends and in the direction of the plane formed by the filed or strung heddles, comprise at least one aperture by means of which the heddles are strung on an independent filing or stringing element, such aperture being in addition to the normal openings for the heddle guidnig rails and the warp threads.
Various forms of the invention are shown by way of example in the drawing, in which- FIGS. 1 to 4 show in elevation heddles having hookshaped ends.
In the drawing, the heddles only are shown with one of the hook ends and with part of the heddle shaft.
In FIG. 1, the heddle 1a at one end comprises a hook 2a which is engageable in a corresponding U-shaped groove of a guide rail 3 which, for example, is rigidly connected to the shaft-supporting bar or is integral therewith. At 4, hook 2a is welded or brazed to heddle shaft 1a.
At the end of hook 2;; adjacent the heddle shaft there is provided an aperture in the form of an oval hole 5. A similar hole is provided in the lower hook (not shown). The heddle is filed or strung through the two holes 5 on two wires or bars 5a.
In FIG. 2, a rectangular or square opening 6 is provided in the heddle end adjacent the heddle shaft 1b. The heddle is strung through the two holes 6 on two wires or bars 6a.
Patented Jan. 16, 1.962
In FIG. 3, a keyhole-shaped perforation 7 is provided on the end of hook 20 adjacent heddle shaft 10. The latter consists of a circular wire which is rigidly connected to hook 2c such as by brazing. Here also, heddle 1c is strung on two wires or bars 7;; through the upper and the lower (not shown) perforations 7.
In FIG. 4, the heddle M is similar to that shown in FIGS. 1 and 2, and the aperture in the outer end of hook 2a, i.e. the end adjacent the heddle shaft, is disposed in the form of a keyhole 8, a similar hole being provided also on the lower hook. The filing wire or bar is designated by 8a.
The holes 5 to 8 serve in principle for stacking and holding together the heddle with other heddles which also are provided with similar holes in the hook end, on filing elements such as wires, bars, profiled laths 5a to 10a, when bundles or packs of heddles are removed from the harness frame or supplied thereto as to a frontal plane assembly. In this way, entire heddle packs filed on the wires may be supplied to or removed from the harness frame in units as a frontal plane assembly without any risk of falling apart.
I claim:
1. A weaving heddle comprising a heddle shaft with a U-shaped hook end and a perforation in the hook end adapted to be filed on a wire so that a plurality of heddles may be removed as a frontal plane assembly from or inserted in a harness frame as a unit, said U-shaped hook end cooperating with a similarly-shaped guide rail when the heddles are mounted in the harness frame.
2. A weaving heddle according to claim 1, in which the perforation is disposed entirely on the end of the heddles.
