Specificationof Letters Patent.

Application filed April 12, 1916. Serial No. 90,656.

especially to those in which the heddle-eye or mail is suspended by a loop or between loops of textile cord or twine.

It relates especially to the means for engaging the mail with one or both of the cords of the heddle.

Our object is to provide a heddle having amail, preferably of metal, which can be easily and economically manufactured and secured to the heddle cords by hand or by automatic machinery, which, when so secured, will not permit the cord to slip through, and which has no projecting points or angles in such position that they can chafe and wear out any other parts.

Our invention is suitable for use in a cot ton mail harness or for a Jacquard heddle. It is customary to cement together the two legs of the top loop of the cord by van nish, but to leave the two legs of the bottom loop of the cord separate in order that a lease may be taken. It is necessary withsuch harnesses and heddles to loosen them up for drawing in the warp, by hand or machine, and for other purposes, and when this is done, the mail is likely to slip down on the cord thus chafing it and wearing it out. With our device such slipping of the mail is impossible, and the heddle will therefore wear longer.

We accomplish our object by forming an extension or extensions at one or both ends of the mail and preferably integral therewith, by passing a hecldle cord or twine through an opening adjoining an extension, by crossing the cord, and by so bending the extension or extensions into engagement with the cord as to lock it in position. The parts are then preferably varnished to cement them more firmly in place and to fill the spaces between the adjoining parts of the cordand the mail. All ed es and ends of the mail should be smooth and rounded so that when the parts are rar nished, there are no rough places to wear out the warp threads.

lVhile we describe our device as applied to one end of the mail and in connection with the bottom cord of a heddle, it is evident that by reversing, the bottom becomes the top, and it is evident that we may use it in connection with both ends of the mail if desired.

In the drawings Figure 1 is a front elevation and Fig. 2 a side elevation of our mail strung on harness cords during the process of manufacture. 3 is a front elevation and Fig. a side elevation of our mail with the adjoining parts of the harness cords as it appears when finished. Fig. 5 is a front elevation of a modified form of mail. Fig. 6 is a detail of another modified form before the mail is strung and before the extension is bent into holding position;

' Fig. 7 shows the mail strung and the extension bent in the holding position, while Fig. 8 is a side view of Fig. 7. Fig. 9 is afront detail view of another modification before the extension is bent into holding position. 10 shows the mail strung and the extension bent into holding position, and Fig. 11 is a bottom sectional view on the line X Y of Fig. 10 considerably enlarged.

In the drawings, the sizes are shown as considerably larger than is customary for the sake of clearness.

A represents a top cord, B is the mail and C is the bottom cord. The mail is formed of a Hat piece of metal or other suitable material and has an elongated opening through which the warp thread is adapted to be passed, together with end openings 21 and 22 through which the cords A and C are respectively adapted to be passed. The cord A is of a well known construction and is formed as a loop with legs and 31 which, as shown in Figs. 3 and 4c, are brought together and cemented, ordinarily by varnishing, in such manner that they cannot slip through opening 21.

At one end, we form extensions and 4-1 which are preferably integral with the material of the mail, and, as shown, are parallel fingers 4:0 and 41, the spaces between being sufiicient to permit the passa e of the two legs and 51 of the cord C. I hose fingers 40 and ii, with the adjoining upon the cords A and C by passing them respectively through openings 21 and 22, and after being so strung, the legs 50 and 51 of the cord C are crossed between the fingers a0 and ll, the ends of which are then bent between the crossed part of the cord to lock it in position. After this is done, the whole heddle is ordinarily varnished in such manner that the two legs 30 and 31 oi the cord A are cemented closely together and to the opening 21, while the cord 0, where it passes through opening 22, is crossed between the fingers 40 and 41 and is cemented in position, all spaces between the adjoining parts of the cord and the mail being filled with the varnish V. The rest or" the legs 50 and 51 are not cemented together, however, and it is possible to pass the hand between them in order to take a lease.

The body of the mail 13 is of well known form with the exception of the extensions or fingers l0 and II. In Fig. 5, we show a mail of substantially another well known form. This mail II is substantially oval with a warp opening 60 and an opening 61 for the top heddle cord, and an opening 62 for the bottom heddle cord. The finger 63 before being bent is shown as an elongated extension of one side of the mail and the finger 64 as a short extension of the other side. The bottom cord is passed through opening 62, then crossed between 64: and 63, after which, finger 63 is bent between the legs of the cord as shown by the dotted lines until it touches finger Gl, thus locking the cord in place.

In Figs. 6, 7 and 8, we show a mail F of the general form shown in Figs. 1, 2, 3, 4, with a bottom opening 70 and a single extension or finger 71. As shown in Figs. 7 and S the bottom cord C is passed through opening 70, then crossed, and finger 70 is bent down in such manner as to engage one or both legs 50 and 51.

In Figs. 9, 10 and 11, we show a mail L of the general form shown in Figs. 1,2, 3. 4:, having an end opening 80 and a long, slim extension or finger 81. The bottom cord C is passed through this end opening 80 and is then brought down and crossed adjoining finger 81, which is then bent at a sharp angle as shown in Fig. 11, around both legs 50 and 51, and back upon itself so that its tip 82 will not project beyond the side lines of the mail L. A greater pitch or twist than is shown may be given finger 81 in winding it around the legs of the cord.

We claim 1. In a heddle, a mail having an opening through which a warp thread is adapted to be passed, end openings, and fingers at one end, in combination with a cord which is passed through the end opening adjoining the fingers and is then crossed between them, the fingers being bent between the crossed parts of the cord to lock it in position.

2. In a heddle, a mail having an opening through which a warp thread is adapted to be passed, end openings and fingers atone end, in combination with a'cord which is passed through the end opening adjoining the fingers and is then crossed between them, the fingersbeing bent between the crossed parts of the cord to lock it in position, together with varnish which substantially fills the spaces between the adjoining, parts of the cord and the end of the mail.

3. In a heddle, a mail having an opening through which a warp thread is adapted to be passed, end openings, and a finger at one end, in combination with a cord which is passed through the end opening adjoining the finger and is then crossed the finger being bent between the crossed parts of the cord to lock it in position.

4. In a heddle, a mail having an opening 7 through which a warp thread is adapted to be passed, end openings, and an extension at one end, in combination with a cord which is passed through the end opening adjoining the extension, such'extension be ing so bent into engagement with the cord as to lock it in position.

In testimony whereof we hereto .aifix our signatures.
