' HEDDLES Filed Sept. 7. 1966 /NVE/VTO? FRAN/f H. KAUFMA/VN ATTO/PNE)l United States Patent O 3,349,811 HEDDLES Frank H. Kaufmann, Huntingdon Valley, Pa., assiguor to Steel Heddle Manufacturing Company, Philadelphia, Pa., a corporation of Pennsylvania Filed Sept. 7, 1966, Ser. No. 579,454 6 Claims. (Cl. 139-96) ABSTRACT OF THE DISCLOSURE Heddles for use with automatic drawing-in machines and other purposes in which each heddle has at the central portion thereof upper and lower warp eyes for reversibility end for end in the event of wear.

This application is a continuation in part of my prior application filed Sept. 13, 1965, Ser. No. 486,932, now abandoned.

This invention relates to heddles used in weaving looms for the purpose of separating the warp ends into sheds for the passage of the shuttle therethrough to effect the weaving operation.

This invention further relates to heddles of the type which are made from a thin flat strip of metal or other suitable material, suitably punched, and formed to the desired shape and which can also be used in installations in which automatic drawing-in machines are used for entering the warp in the harness, and for other purposes.

Heddles heretofore available for this purpose had a limited life since upon the occurrence of wear of the warp carrying eye the heddle was discarded.

It has heretofore been proposed to provide heddles having a plurality of vertically spaced warp carrying eyes but these were provided all facing in the same direction. This would involve serious problems of entering if one warp eye was worn and it was desired to use another. Reversibility end for end cannot be achieved with warp carrying eyes all facing in the same direction.

The principal object of the present invention is to provide a novel form of heddle made from a thin iiat strip of metal, or other suitable material, which will have a longer useful life than heddles heretofore employed, and which, in one aspect, is also suitable for use with drawingin machines of well known type.

A further object of the present invention is to provide a heddle suitable for use with drawing-in machines and for other purposes and which has a plurality of warp receiving eyes, either of which can be employed upon turning of the heddle end for end, and which will in either position present an open or left handed eye for the entering of the warp.

A further object of the present invention is to provide a heddle suitable for use with drawing-in machines and for other purposes, which has a plurality of warp receiving eyes and which can be readily constructed without presenting any manufacturing problems.

A further object of the present invention is to provide a heddle suitable for use with drawing-in machines and which has a plurality of warp receiving eyes for selective use and in which the eye selected for use will not provide a tortuous path for the warp.

A further object of the present invention is to provide a heddle, and whether or not for use with drawing-machines, which will upon turning on the heddle rods present a warp receiving eye of proper hand for access by the weaver.

Other objects and advantageous features will be apparent from the description and claims.

The nature and characteristic features of the invention will be more readily understood from the following description, taken in connection with the accompanying drawing forming part hereof, in which:

FIGURE 1 is a front elevation of a group of heddles in accordance with the invention;

FIG. 2 is a vertical sectional view taken approximately on the line 2-2 of FIG. 1, and showing one of the heddles in side elevation;

FIG. 3 is a vertical sectional view taken approximately on the line 3-3 of FIG. 1, and showing another of the heddles in side elevation, and

FIG. 4 is a view of another heddle in accordance with the invention with a plurality of warp receiving eyes presenting an upper open eye for one position of the heddle and the same eye open if the heddle is turned end for end.

It should, of course, be understood that the description and drawing herein are illustrative merely and that various changes and modifications may be made in the structure disclosed without departing from the spirit of the invention.

Like numerals refer to like parts throughout the several views.

In accordance with the present invention an improved heddle is provided with a plurality of -warp receiving eyes, preferably one above and one below the center of the heddle, and respectively facing in different directions i.e., one an open or left handed eye and the other a less accessible or right handed eye, so that upon turning the heddle end for end the upper eye is always the same. The warp receiving eyes may have disposed therebetween a keyhole slot oriented as desired for engagement lby the selector mechanism of the drawing-in machine.

Referring now more particularly to the drawings each of the heddles 10 there shown is made from a thin flat strip of metal or wire, or other suitable material, the stock preferably being of the full width of the finished heddle. 4

The heddle 10 preferably has opposite end portions 11 of the full width of the strip, a central portion 12 of the full width of the strip, and conne-cting portions 13 of reduced width to reduce the weight of the heddle 10.

The connecting portions 13 can, if desired, be provided with heddle separating offsets or spacers 14 to space the heddles 10.

The end portions 11 of the heddles 10 can each be provided with a mortise or slot 15 serving as a rod eye for mounting the heddles 10 on upper and lower heddle supporting rods 16.

One of the side Shanks 17 at each of the mortises is preferably cut away at the side, as at 18, so as to permit the heddles to pass freely from end to end on the heddle supporting rods 16 when said heddle rods 16 are supported in the heddle frame. Suitable heddle frames are shown in Patents Nos. 2,047,511 and 2,386,690 which will permit freedom of movement of the heddles 10 on the Supporting rods 16.

If desired, and as shown in FIGS. 2 `and 3 the central portion 12 of the heddle 10 can be provided, intermediate its extremities, with at least one keyhole slot 20 of known type and oriented as desired for engagement by the selector mechanism of the warp drawing-in machine.

Above the center of the heddle 10, a warp eye 21 is provided with its

margins

22 and 23 offset respectively in opposite directions from the main plane of the strip to provide a large effective eye for the size of the strip material, the warp eyes 21 all having their

margins

22 and 23 offset in the same manner so that they face in the same direction. A

Below the center of the heddle 10, a warp eye 24 is provided with its

margins

25 and 26 offset respectively in opposite directions from the main plane of the strip, and oppositely from the

margins

22 and 23, providing large effective eyes, the warp eyes 24 all having their

margins

25 and 26 offset in the same manner so that they face in the same direction but oppositely from the warp eyes 21.

Heddles of the character herein described may be readi ly and inexpensively made without problems as to their formation. The Weight is reduced by shearing out portions on each side thereof along the connecting portions 13.

The warp eyes 21, above the centers of the heddles are at suitable locations and properly faced to conform to standards in Europe.

The warp eyes 24 are in the normal direction for entering by the drawing-in machine commonly used in the United States while the eyes 21 are not suited for easy entering in the conventional manner.

Upon the occurrence of wear either at the warp eyes 21 or at the warp eyes 24, the heddles can be turned end for end and the other warp eyes employed. No difficulties will then be encountered for above center warp thread control by the eyes 21 or for drawing-in of the warp threads through the lower eyes since they will all face in the same direction, and in the direction for which the drawing-in machine was previously operated.

It will accordingly be seen that heddles have been provided with which the objects of the invention are accomplished.
