Pa., a corporation of Pennsylvania Fiied June 5, 1967, Set. N0. 643,510
U.S. Cl. 139-91 Iut. C]. D03c 9/06; D02h 13/16;D01h 11/04 4 Claims ABSTRACT OF THE DISCLOSURE Heddles for the harness of weaving looms with separating provisions at the warp controlling eyes of the heddles preventing nesting of the heddles.
BACKGROUND OF THE INVENTION Field f the inventz'on This invention relates to loom harness and more partieularly to the heddles in harness of the type used in water jet looms.
Description 0 the pri0r art SUMMARY OF THE INVENTION It is the principal object of the present invention to provide an improved heddle construction at the warp eyes for providing a separation of the heddles at the warp eyes thereby eliminating nesting of the heddles It is a further object of the present invention to provide an improved heddle construction Which is simple laut eflective for preventing nesting of heddles at their warp eyes, and particularly in water jet looms.
It is a further object of the present invention to provide an improved heddle construction in which, in a preferred embodiment, alternate heddles, at their warp eyes are shaped to prevent nesting.
Other objects and advantageous features of the inven tion will be apparent from the description and claims.
BRIEF DESCRIPTION OF THE DRAWING The nature and characteristic features of the invention Will be more readily understood from the following description taken in connection with the accompanying drawings forming part thereof, in which:
FIGURE 1 is a view in elevation of One of a pair of related heddles in accordance with the invention, the rods upon which the heddle is mounted being shown in section;
FIG. 2 is a view similar to FIG. 1 showing in elevation another of a pair of related heddles in accordance with the invention;
FIG. 3 is a front elevation of a pair of heddles of the type shown in FIGS. 1 and 2, and illustrating the separating action at the warp eyes, parts of the heddles being omitted; and
FIG. 4 is a fragmentary perspective view of the mid portions of a pair of related heddles.
It should, of course, be understood that the description and drawings herein are illustrative merely, and that various modifications and changes can be made in the structure disclosed without departing from the spirit of the invention.
Like numerals refer to like parts throughout the several views.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring W more particularly to the drawings heddle rods 10 and 11 of well known type are shown, these being mounted as is well known in harness frames (not shown).
A multiplicity of heddles 12 and 13 are mounted on the heddle rods 10 and 11, in a well known manner.
The heddles 12 and 13 are preferably made of thin flat strips of metal, initially of a uniform width corresponding to the widest portion of the heddle. The central ortion 14 of each heddle 12 or 13, and the end portions 15 are preferably the full Width of the strip and the parts 16 of the heddles 12 and 13 are sheared down to a narrower width to provide greater flexibility in the heddles and to reduce the total Weight of the harness.
The end portions 15 of each heddle 12 and 13 are each provided with a slot 18 for mountin-g on the rods 10 and 11 and the slots 18 may have central portions cut away on one side, as at 19, to permit free end to end movement of the heddles 12 and 13 on the heddle rods 10 and 11 and past any center braces and intermediate heddle rod supports, in a well known manner.
Alternate heddles of the heddles 12 and 13 may have spacing projections 20, of well known type, engaging straight portions of contiguous heddles to insure greater freedom of movement of the warp during shedding as well as to facilitate drawing in of the warp.
The central portions 14 cf each of the heddles 12 and 13 may be provided with oppositely downwardly and up- Wardly pointing keyhole slots 21 and 22 for engagement by the drawing-in machine employed -for entering the warp in the warp eyes.
The central portions 14 of each cf the heddles 12 and 13 are provided with punched warp eyes 23 and 24 to receive and control the warp during the weaving operation.
One of the warp eyes of a related pair of heddles 12 and 13, such as the warp eye 23, has the shanks 25 thereof formed in bowed conformation and to a predetermined distance from and on opposite sides of the main plane of the central portion 14.
The other of the warp eyes of a related pair of heddles 12 and 13, such as the warp eye 24, has the shanks 26 thereof also in bowed conformation and to a different predetermined distance, in this instance less than the deformation of the shanks 25 from and also 0n opposite sides of the main plane of the central portion 14. The shanks 25 and 26 are preferably respectively olfset in the same directions rather than in respectively opposite directions so that in successive heddles the engagement of One of the shanks 26 with a contiguous shank 25 is obviated by reason of the diiferent shaping or curvature of the shanks, spacing of the remainder of the central portions 14 of the heddles 12 and 13 is eflected and adherence of heddles 12 and 13 at the warp eyes 23 and 24 is prevented. At the same time relatively close spacing of the heddles 12 and 13 can be effected and the space within the harness frame utilized.
It will thus l: e seen that provisions have been made f01' attaining the objects of the invention.
I claim:
1. Loom harness comprising a plurality of heddles of thin flat strips top and bottom mountings,
each of said heddles having a central portion intermediate the top and bottom mountings provided With a warp eye,
of metal having each of said warp eyes having its shanks Offset in opposite directions from the main plane of the cantral portion,
the shanks of the warp eye of one heddle being Offset to a greater extent in a predetermined direction than the corresponding shanks of the warp eye of an adjoining hedd1e thereby to space the heddles at their warp eyes.
2. Loom harness as defined in claim 1 in which said heddles have the corresponding s'hanks of successive heddles offset in the same direction.
3. Loom harness as defined in claim 1 in which successive heddles at the central portions have oppositely pointing keyhole slots.
4. Loom harness as defined in claim 1 in which said heddles contiguous to the top and bottom mountings 11ave additional spacer members.
