PATENT HARNESS FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 779,193, dated January 3, 1905. Application filed December 14, 1901. Serial No. 35,976.

To all whmn it may concern:

Be it known that I, PAUL A. WAGNER, a citi- Zen of the United States, and a resident of Carlstadt, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Harness for Looms, of which the following is aspecification.

This invention relates to improvements in loom-harness; and the object of my invention is to provide a new and improved loom-liar ness which is strong, cheap, and durable and simple in construction.

In the accompanying drawings, like letters of reference indicate like parts in all the figures.

Figures 1 to 11 are various constructions of my improved loom-harness.

The harness is of the style in which the heddles are formed of single threads extending from the edges to the central line of the har ness or from edge to edge.

In the drawings, A represents the caudlewarp in all the figures, and theharness is held on the candle warps by permanent eyes formed along the edges of the harness either at the ends of the heddles or between the ends of the heddles. By permanent eye I mean to designate or define an eye made from or out of the thread or strand from which the heddle is made or another thread and having a permanent or unchangeable structure, so as to distinguish it clearly from eye formed by looping the thread around the candle-warp and drawing the thread taut, in which latter case the dimensions of said eye must evidently depend on the larger or smaller diameter of the candle-warp and more or less on the tightness of winding of the latter or the tension in the thread.

The permanent or irreducible quality of the eyes or loops permit the harness to be contracted or expanded easily upon the candlewarps in accommodating the spacing of the heddles to conform-to the number and spacing of the warp-threads in the loom. In the usual knitted or woven thread harness in which the eyes are formed bya bight or loop around the candle-warp, the bights or loops tighten and grasp the candle-warp so firmly as to prevent,

or at least seriously interfere with, the required shifting thereon. My improved harness avoids this difiiculty. The permanent or unchangeable quality of the eyes offers a further advantage in that by refusing to loosen or stretch they insure a definite and unchanging length of heddle on each side of the shaft when in place thereon and subjected to the strains of service. For example, as shownin Fig. 1, the permanent eyes B, through which the candle-warp A is passed, are formed by twisting the thread a one or more times at the bottom of the eye B, and the thread a may extend from one heddle to the next, as shown at 7).

As shown in Fig. 2, the eyes B are formed by crossing the thread a at the bottom of the eye B and applying some adhesive substance (Z at the crossing to hold the crossed parts of the threads together.

Asshown in Fig. 8, the eyes B are formed by knotting the threads (0 directly below the eye, as at g As shown in Fig. 4, the eyes If are formed by uniting the threads 60* directly below the eye by means of a metal or other clip 0*.

Fig. 5 shows the arrangement of a series of heddles upon a pair of shafts M M. This harness is of the form shown in Fig. 1.

As shown in Fig. 6, the eye may be formed by the part c of the heddle-thread extending from one heddle to the other, the eye being formed and held by a cord or thread F, wrapped around the adjacent heddle-threads permanently and, if desired, extending from one heddle to the next.

As shown in Fig. 7, the threads (4 forming the heddles, are carried at the edge of the harness from one heddle to the next, and a strand F of silk, thread, or fine wire is wound around that part of the heddle-thread extending from one heddle to the next, so as to hold the ends of the heddles in place, and part of this strand F of silk, wire, or thread is bent to form permanent loops or eyes B through which the candle-warps can be passed.

As shown in Fig. 8, the strands F can. also be wound around the two threads of the heddles for a greater or less length and need not be wound around the parts connecting the heddles; but the permanent eyes B are also formed by such strands on the ends of the heddles.

As shown in Fig. 9, the heddle-threads extend to a binder-thread J and are secured on the same by winding a fine strand F of silk, wire, or thread around the closed ends of the heddles and the binder J, and the permanent eyes B are formed on the binder J, which is looped to form such eyes, which are made permanent by the strands F, Wound around parts of the heddles and the binder.

As shown in Fig. 10, the strands F are wound around the binder J and the closed ends of the heddles and the eyes B are formed in and by said strands.

As shown in Fig. 11, the eyes B are formed by making a double loop or eye out of the heddle-thread a, and these eyes or loops are then made permanent by applying on them a solution of rubber, glue, or the like, as represented by m.

In all constructions shown and described the eyes by which the harness is held on the caudle-warp A are permanent and cannot be increased or decreased in size by pulling strains, and they are not dependent in their size upon the size of the candle-warps.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A continuous harness of thread having permanently-formed or unchangeable loops or eyes on its outer edges or margins, in combination with caudlewarps received in said loops or eyes.

2. A harness composed of heddles the upper and lower portions formed each of a continuous thread looped at the margin to form a closed permanent eye for each heddle, in

- combination with a candle-warp for each margin received in said eyes.

3. A continuous harness of thread having eyes or loops on its outer margin or margins,

said loops or eyes being permanently held in proximity to the bottoms thereof, in combination with candle-warps received in said loops or eyes. 1
