atoms FOR 'JACQUARD LOOMS.

QPEGiFICA TION forming part of Letters Patent No. 587,472,'da.ted August 3, 1897.

Application filed January 23, 1897. Serial No. 620,346. (No model.)

To (all whom it may concern;

Be it knownthat I, EDWIN BUTCHER, a citi' zen of the United States, residing at \Vorcester, in the county of l-Vorcester and State of 5 Massachusetts, have invented certain new and useful Improvements in Heddles for Jacquard Looms, of which the following is a specification.

My invention relates to heddles for Jacquard i looms, and more particularly to an improved construction of a wire heddle intermediate the cord leadin g to the jacquard and the lingo and to an improved way of attachin g the lingo to the lower end of the heddle. It will be nn;

I derstood that the threadswhich form the fig.- ure in weaving the fabric extend through the heddle-eyes, and that the Jacquard machine controls the raising and lowering of the hed dies and the threads, according to the indi-. 2o cations of the pattern-cards.

x The object of my invention is to provide a two-strand wire heddle with an eye therein intermediate its ends for the thread to pass through, said eye consisting of an oval-shaped metal eyelet secured between the two strands;

and another object of my invention is to attach the lower end of the wire heddle to the lingo by means of a tube without twisting the ends of the wire.

My invention consists in certain novel features of construction of my wire heddle and the manner of attaching the same to the lingo, as will be hereinafter fully described.

Referring to the drawings, Figure l showsa wire heddle embodying myimprovements attached at its upper end to the lower end of the cord leading to the Jacquard machine and at its lower end to the upper end of a lingo. Fig. 2 is a detached view of a heddle- 4c eye: Fig. 3 is a transverse section through the eye on line 3 3, Fig. 2, looking in the direction of arrow a, same figure. Fig. 4 shows the lower end'of the wire heddle with the tube thereon preparatory to attaching the lingo thereto. Fig. 5 shows the next step in attaching the lingo: The ends of the wire have been bent up and passed through the eye in the upper end of the lingo from opposite sides. Fig. 6 shows the next step: The ends of the wire have been bent up again against the main wires and inserted in the lower end of the tube, which is then drawn down on the 'four strands of wire, as shown. Fig. 7 shows the next step: The two free'ends of the wire are bent outwardly-in opposite directions to extend over the top edge of the tube. Fig. 8

the wires are out offclose to the tube, leaving the hooked ends extending over the up.- per edge of the-tube; and Fig. 9 is a trans verse section on line 9 9, Fig. 8, looking inthe shows the next step: The projecting ends of direction of arrow 1), same figure. Figs. 2 to 9, inclusive, are shown on an enlarged scale. In the accompanying drawings, 1 is the lower end of a cord leading to the Jacquard machine, to which is attached the upper end of my wire heddle 2. The lingo 3 (only the upper part of which is shown) is of ordinary shape and construction and has an eye 3 at its upper end, by which it is attached to the lower end of the heddle-wire 2.

The heddle-wire 2 is prcferablyinade from between its upper and lower ends an oval- 1 I shaped eyelet 5, having itsoutcr edge grooved or recessed, is placed between the two strands of the heddlewhich extend in the grooved edge of the'eyelet 5, and thetwo strands are twisted together just above and just below the eyelet 5 to secure it in place. (SeeFig. 2.)

The eyelet portion of the heddle-wire '2 is preferably tinned or coated with metal'\to fill any 0 ening or joint and make a smooth and even. rface which will not catch on'or chafe or rub the worsted threads es the heddle-' wires are raised and lowered.

Upon the lower free ends'2 of the heddlewire 2 is strung a tube 6, (see Fig. 4,) which has an =internal-diameter jus't large enough to receive tour thicknesses of the single wire or strand from which the heddle is made. After the tube 6 is'placedon the lower end of the are bent up and passed through the eye 3 of the lingo from opposite sides, as shown in Fig. 5. The ends 2 are then bent up against wire heddle the free ends 2 of the twowires Y the body or main portion of the heddle-wire 2 and the tube 6 drawn down over the four strands of wire (see Fig. 6) as far as it can be to form the loop 7 in the lower end of the heddle-wire for the lingo 3. i

The ends 2, which preferably extend upon opposite sides of the mainwires of the heddle, are then bent outwardly in opposite directions to extend over the to edge of the tube 0, (see Fig. 7,) and the projecting ends are then cut oil close to the tube, as shown in Fig. 8, leaving hooked ends extending over the top edge of the tube 6, (see Fig. 9,) which pre vents the tube from slipping or moving up on the wires.

It will be seen that the tube 6 must remain in its place on the lower end of the heddlewire and cannot work loose because it cannot move down by reason of the divergence of the wires to form the loop 7, and it cannot move up by reason of the hooks 8 extending over its upper edge, and by means of the tube the free ends of the wire are secured to the body or main part of the heddle to form the loop 7 for the lingo 2 without any twisting of the ends or any soldering, 1X30.

The advantages of my improvements in wire heddles for Jacquard looms will be readily appreciated by those skilled in the art. They are very durable and will not wear out, and the eyelet portion is smooth and even and will not rub and chafe the threads. By means of the tube theiingo can be quickly and readily attached and secured to the lower end of the wire heddle.

It will be understood that some of the de- I claim as new, and desire to secure by Letters Patent, is-

1. A wire heddle for Jacquard looms, having an eye or loop at its upper end, a heddleeye intermediate its ends, and a loop or eye at its lower end, and a tube thereon to secure the lower ends of the wire to the main portion or body of the heddle, substantially as shown and described.

2. The combination with a wire heddle for Jacquard looms, having an eye or loop at its upper end, of a tube on its lower end, through which the free ends of the wire extend, and are bent over the upper edge of the tube, to secure it in place on the wireheddle, and form an eye or loop at the lower end thereof for the lingo, substantially as shown and described.

The combination with a wire heddle for Jacquard looms, having an eye or loop at its upper end, a heddle-eyeintermediate its ends, and a loop or eye at its lower end, of a tube mounted or strung on the wire heddle just above said loop or eye, and secured thereon by bending the free ends of the wire strands over the upper edge of said tube, sub.-;tantially as shown and-.described.
