i SPECIFATIN forming part of Letters Patent No. 224,797, dated February` 24, 1880. i Application filed September 10, 1879. Patented in Germany, October 2, 1877.

y 5 in Heddles for Looms, of which the following f isa specification. I

In the accompanying drawings, Figure l represents a front elevationof my improved heddle; Fig. 2, a vertical transverse section of tail front view of the heddle-eye, and Fig. 4 a

sectional front and side view of the metallic cords or threads, in which the heddle-eyes are formed either directly by the intermeshing of zo the loops or by the employment of small oval and perforated steel plates. These heddle constructions have the following disadvantages First, a lack of durability. The heddles, especially in power'looms, wear out very rapidly, and require, therefore, frequent repairs.

Second, they can only be used for the special fabrics for which they are made up, each fabi ric or material requiring a separate heddle.

Third, the heddle-cords, even when carefully varnished, are not smooth enough for the nny `impeded passage of the warp-threads, and

cause the entangling of the loops, by which l faults are produced in the fabrics. y y

` To overcome these objections the heddlecords have `been made of twisted wire with an eye formed at the center by an interruption ofthe twist. Experience, however, has shown that these `Wire leaves lare not better. than the common cords, buteven less effective,as the eye is imperfect and cuts the Warp-threads, andas the cords are too rigid and become un.- even by bending. Heddle-loops with metallic eyes bent of wire y or stamped out of `1netal have also been used heretofore, saidloops being made of a continy nous piece of wire that passed through the eyes.

i and over the hangers `or bars of the heddles. This construction, however, cannot easily be repaired, owing to the continuity of the wire.

i i 1, 5o y My invention is designed to remove entirely the same on line .fr Fig. 1. Fig. 3 is a de the objectionable features described; and it consists of loops of dat steel wire which are passed through central steel eyes or mails. The flat-Wire loops are clasped at the ends by sheet-metal rings or eyes, which are placed loosely on detachable transverse rails, of which the lower is adjustable, so as to impart a greater or less tension to the heddle-loops.

By reference to the drawings, A A are the heddleloops, which are made of thin flat and 6o smooth steel or other Wire that is lightly rounded off at the edges. The Wire loops A are passed through holes of the central steel eyes, B, the elongated holes of which serve to guide the Warp-threads. The ends of the wire loops A are clasped and iirmly held by sheet. metal eyes or rings C, which are shown clearly in Fig. 4.

The required number of heddle-loops are strung up by their end rings on transverse 7o steel rods or rails D, which are supported by the wooden heddle-frame D. The upper rail,

D, is supported on screw-hooks D2, and passed through holes of' the frame, while the lower rail is guided in slots a of the frame and drawn 7 5 down or let up again by lower screw-hooks, D2.

The wire loops B are made by machinery, so that they are all of the same size. They can therefore be all stretched to the proper tension at the same time, leaving no loose loops, 8o which, in the common heddles, can never be altogether avoided, and which exert an injurious influence on the even texture of the fabric.

The Wire loops, as well as the steel eyes, are

of perfect smoothness, so that the passage of the warp-threads-is not in the least obstructed. The loopsv cannot get entangled, as the metal eyes embrace closely the guide-rails. As the proper tension is given to the loops by the ad- 9o justment of the lower rail there is but little wear of the same.

My improved heddle can, furthermore, be used for weavin g different fabrics, as the number of loops can be increased or decreased at 9 5` pleasure. The rails are for this purpose made removable from the frame by being threaded at the ends and secured by nuts b. The loops slide on the rails and adapt themselves readily to the division of the reeds.

IOO

The steel eyes can also be made of larger or smaller size, with round or oval holes, as they are manufactured independently of the cords.

Injured or worn-out loops can be readily replaced by new oneson removing the rails from the heddle-frame.

When the heddles are exposed to moist air, as is frequently the oase when the weaver works at home, the steel wire has to be galvanized to prevent corrosion.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The combination of the wire leaves or loops A and of veonneoting steel heddle-eyes with sheet-metal eyes or rings, which clasp the ends of the loops, substantially as and for the purpose described.
