DOUP-HEDDLE FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 228,580, dated June 8, 1880.

Application filed J annary 16, 1880.

To all whom it may concern Be it known that I, GEORGE ZIEGLER, of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Doup-Heddles for Looms, of which the following description, in connection with the accom panying drawings, is a specification.

This invention relates to looms, and has for its object a construction, such as hereinafter described, of the warp-controlling mechanism, whereby the warp may be shed as for cross or for plain weaving, as may be desired or indicated, by a pattern-surface or Jacquard card.

My invention consists, chiefly, in a compound or duplex heddle for controlling the warp, as hereinafter described.

One part of my compound heddle,'callcd by me the eye part, contains an eye which receives the warp-thread, and the other part, called the guide part, receives, guides, The eye part is carried by one and the guide part by another harnesstrame, and cooperating with the said eye and guide parts and their carrying-frames are other harness-frames having heddlesof ordinary construction,one of which harness-frames, as hereinafter describedviz., the one which operates upon the same warpthreads that are extended through the eye partshas imparted to it a greater movement than is imparted to the other adjacent harnessframes, this greater movement of the said harness-frame causing its warp-eyes to so lift the eye parts of my compound heddle as to cause the eyes of the said eye parts to rise sufficiently above the encircling portion of the guide part to hold an adjacent warp-thread between it and the guide part.

Figure 1 represents, in vertical section, four harness-frames, two of which contain heddles of usual construction, while the other two carry my compound or duplex heddles; Fig. 2, a similar section, showing the parts in a different position; Fig. 3, a front View of Fig. 1, one of the encircling portions being shown in vertical section; Fig. 4, a modified form of guide part adapted for a jacquard; Fig. 4, a section on, the dotted line :0 :0, Fig. 4; Fig. 5, a modified form of parts, and Fig. 6 a modified eye part.

In the drawings I have shown four harness frames, 1 2 3 4. The frame 4 is most remote from the breast-beam or front of the loom. The frames 4 3 have warp-eyes 5, of usual construction, attached in the usual manner, by threads 6, with the top and bottom bars of the said harness-frames. The harness-frame 1 has connected with its lower cross-bar the eye parts a of my compound heddles, such parts being composed of fine wire, (shown in Figs. 1 to 3 and 5 as twisted together to form at their upper ends eyes 7;) butinstead of forming the eyes 7 as parts of the wire I may, if desired, employ separable eyes of glass or other material, as shown at 00, Fig. 6. The harnessframe 2 has heddle-rods 8, upon which are placed the guide parts I) of my compound heddles, they being herein represented as composed of sheet metal, so bent, folded, or constructed as to form encircling, guiding, or directing portions 0, into which the eye portions a are inserted and guided. The encircling portion 0 is formed at one side of the guide part b, and, as clearly shown in Figs. 3 and 4, is located substantially opposite the opening in the part I), through which the eye part a works.

The guide portions 1) maybe of metal or of india-rubber or other equivalent compound. Instead of making the encircling portion 0 short, as in Figs. 1 to 3, it may be made as a long tube, as in Fig. 5.

In Fig.4I have shown the guide part adapted at its upper end to be connected with a Jacquard cord and weighted or provided with lingoes l.

I will suppose that I am about to weave a fabric with, say, a blue warp, (shown by the single line 01,) and with a white warp, (shown by the double line 6.) The Warp e is extended through the eyes 7 of the eye parts a, and then through the heddle-eyes of, the frame 4, and the warp d is threaded through the heddle-eyes of the frame 3. The eye parts a, connected with frame 1, are extended up through the encircling portions 0 of the guide parts I) of the frame 2.

The frames 1 2 3 will, in practice, he raised and lowered equal distances by any usual devices, not necessary to be herein shown as such devices form no part of my invention; but the frame 4 will have its lifting strap or cord f connected with a collar, g, of sufficient diameter, located on a shaft, h, to lift the said frame higher than are lifted any of the adja cent harness-fram es, to thereby permit the said harness-frame 4, as illustrated in Fig. 1, to be raised high enough to cause the warp 0, held by it and extended through the eyes 7 of the eye parts, to lift the said eye parts, as shown in Fig. 1, and cause the warp cl in the warpeyes 5 of the harness-frame 3 to beheld between the eye part a and the side of the guide part b above the encircling part c, in which the eye part moves, the warp (1 being then thrown to the right of the warp 0.

To throw the warp d to the left of warp 0 it is only necessary to lift the harness- frames 1 and 2, when the eye part 7,then holding the warp 0 at or just within the encircling part 0, acts upon and lifts the warp e at the righthand side of warp d, the latter warp passing down over the inclined part 10 of the said on circling part c, the eye 7 being then drawn below the upper surface of the said encircling portion 0, as in Fig. 2.

Instead of wire, I may use a small strand or strip of sheet metal, or a fibrous thread made very stiff by the application of glue and shellac, the thread being twisted and pressed to stiffen it.

By changing the positions of the heddleframes, as described, it is evident that crossweaving may be done.

I am aware that cross-weaving is now commonly done by drawing one thread-like hed dle through the eye of another heddle; but in such plan the threads are rapidly worn, which causes delay in weaving as well as expense in substitutingnew threads.

My compound cross-weaving heddle is very simple, efficient, and durable, and is more economical than the old form of thread-heddles.

Each guide part b, as shown in Figs. 3 and 4, has in it an opening, 12, communicating with the interior of the encircling portion 0, and when the eye part is composed of wire, as I have herein shown it, the eye part enters the encircling portion through the opening 12. The eye part, by passing diagonally through the said encircling portion, has given to its upper end an outward direction away from the guide part, so that it, to a limited extent, according to the distance of the interior wall of the encircling part c from the contiguous side of the part I), passes the warp d and leaves it between the said eye part and guide part, as in Fig. 3; but to always insure that the rising eye part'shall pass the warp d, carried by the harness-frame 3, at the proper side, I have provided each guide part b with an offset, 14, against which the eyes 7 strike if they are moving too near the sides of the parts I), the said offsets directing the eyes 7 away from the said guide parts, so as to pass outside of the warps 01.

Instead of wire forthe eye part, I might employ a wire made as a needle with an eye at its upper end.

I claim- 1. The compound heddle composed of the eye part a and the guide part I), havingthe encircling portion c,in which the eye part moves and by which it is guided, the said encircling portion being located at one side of the guide part I), opposite the opening 12, substantially as shown and described.

2. The independent harness-frame 1 and its connected metallic eye parts a, combined with the harness-frame 2 and the guide parts 1), provided with the encircling portions 0 at one side of the guide parts I), the said encircling portions being provided with inclined surfaces 10, over which the warps cl pass when the eyes of the eye part a are drawn below the part 10, as shown and described.

3. The eye part a, combined with the guide part I), provided with the encircling portion 0 and with the opening 12 and offset 14, the said opening being located below the said offset, substantially as and for the purpose described.

4. The eye part a, combined with the guide part I), provided with an encircling portion, 0, and the offset 14, to prevent the eye of the eye part, in its upward movement above the encircling portion 0, from passing too close to the guide part, as and for the purpose described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE ZIEGLER.
