J-, J. KAUFMANN HEDDLE Filed July 22. 1951 vent'ion, the same Patented Jan. 3, 1933 PATENT orrics JOHN JACOB KAUFMANN, OF ELKINS PARK, PENNSYLVANIA, ASSIGNOR TO STEEL H'EDDLE MANUFACTURING COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A- COR- roaar-ron or PENNSYLVANIA HEDDLE Application filed July 22,1931. Serial No. 552,402.

My invention relates to heddles' for loom harness, and} it relates more particularly to that type of heddle which is so constructed and arrangedthat one or more or the same may be mounted at any desired place in the frame, either for the purposeof replacing a broken or damaged heddle, or for increasing th number of heddles in the harness frame, without removing the heddle supporting rods from the frame.

My invention contemplates the construction of heddles of the type aforesaid, in which the portion of the heddle is made from a thin fiat strip of metal or wire, having improved means at t 'e ends thereof for mounting the same on the supporting rods.

The nature and characteristic feature of' my invention will be more readily under stood from the follow ng description, taken-- in connection with the accompanying drawing forming part hereof, in which: I

Figure 1 is an edge View of a heddle embodying the main, features of my present inbeing shown mounted on the heddle supporting rods of the harness m 1 Fig. 2 is a face view of the heddle shown in Fig. 1, he supporting rods being shown in section; V v E Fig, 3 is a perspective view of the endportion of the heddle, mounted on the supporting Fig. 4: is a development the endmembers of the heddle; and

Fig. 5 is a perspective View showing the end portion of the heddle in the process of assembly.

It will, of course,

rod;

be understood that the drawing and description herein contained are illustrative merely, and that various changes and modifications may be made in the structure disclosed without departing from the spirit'ofmyinvention.

In the particular emb diment of the invention which is shown in the drawing, 10 is the mainor body portion. of the heddle, which is made of a thin flat strip of metal or wire, and in which the warpeye 11 is formed by slitting and expanding in any preferred manner,

showing the same I view of one of At each end of the heddle there is carried a member 12, for engaging the supporting rod, which member 12 is also preferably made from a thin flat strip of metal. In Fig; 4 of the drawing, the member 12 is shown in its initial form, beforeit is] attached to the body portion of the he'ddle. It will be noted that the same is somewhat Wider than the body portion of the heddle, and is pro- Vided with an aperture 13 through which, the end ofthe body portion of the heddle extends. The member 12 is bent, as at 14, so that a portionthereof embraces the end of the body portion of the heddle onv each face thereof, and is permanentlysecured thereto in any" preferred manner, such for example as by spot welding,- as at 15'. r

The member 12, when secured to the end. of the body portion of the heddle, comprises two parallel legs, each of which is provided with a cut out recess 16, theopening. extendmg to opposite edges of thetwo legs, so that the same-provides, in effect, a slot 17 through wvhich the supporting rod 18 extends when the heddle is mounted in the harness frame- Contiguous to the recess 16, on each leg of the member 12, is a lip portion 19. The lip portions 19 serve to preventthe endsof the leg portions from spreading andbecoming disengaged from the supporting rods 18.

is bent outwardly from the main plane thereof, as at 20, to facilitate the mounting of the he'ddle on the supporting rod.

When it is desired to mount the heddle atthe desired place upon the supporting rods 18, the heddl-e is turned upon its longitudinal axis, at right angles to the positionitnorinal-ly occupies: when mounted on the supporting rods. The member 12 at one end of the heddle is then pushed over its rod with one of the, legiportions on each side thereof, to the extreme inner end of the recess 16, so that the lip portions 19 will be brought beyond the outer edge of the rod 18, after which the heddleis turnedto its proper position.

The end of the heddle will now be. retained.

The end of at least one of the leg portions which the recess leg portions of the member 12 from spreading when the strain is imparted to the heddle;

After one end of the heddle is thus mounted upon its supporting rod, the other end is in like manner caused to engage its supporting rod, it being noted that the heddle may be twisted sufficiently to permit this engagement. I

It will be seen that there is thus provided a heddle which may be inexpensively made, which Will be durable and eiiicient, and which may be readily mounted at any desired place on the supporting rods, either for the purpose of replacing a broken heddle or for increasing the number of heddles in the harness frame.

I claim:

1. A heddle having members at the ends thereof for mounting the heddle on the supporting rods, said members comprising leg portions disposed in separate parallel planes, each of said leg portions having a recess therein open to the side, the recess of one leg portion opening to the side opposite that to opens. I

' 2. A heddle having its body portion made of a thin flat strip of metal or wire, members permanently secured to the side faces of the body portion at the ends thereof for mounting the heddle on the supporting rods, said members comprising leg portions disposed in separate planes, each of said leg portions having a recess therein open to the side, the

recess of one leg portion opening to the side opposite'that to which the leg portion opens.

3. A heddle having its body portion made of a thin fiat strip of metal or wire, members permanently secured to the side faces of the body porticnat the ends thereof for mounting the heddle on the supporting rods, said members comprising substantially parallel leg portions each having a recess therein open recess of the other to the side, the recess of one leg portion opening to the side opposite that to which the recess of the other leg portion opens, and lip portions contiguous to said recesses adapted to overlap the sides of the supporting rod.

l. A heddle having its body portion made of a thin fiat-strip of metal or wire, members secured to said body portion at the ends thereof for mounting the heddl on the supporting rods, said members being made of thin fiat metal and comprising leg portions disposed in separate parallel planes, each of said leg portions having a recess therein open to the side, the recess of one leg portion opening to the side opposite that towhioh the recess of the other leg portion opens. 5. A heddle having its body portion mad of a thin fiat strip of metal or wire', members secured to said body portion at the ends thereof for mounting the heddle on the supporting of the other leg portion' rods, said members being made of thin flat metal and comprising leg portions disposed in separate parallel planes, each of said leg portions having a recess therein open to the side, the recess of one leg portion opening to the side opposite that'to which the recess of the other leg portion opens, and lip portions contiguous to said recesses adapted to overlap the sides of the supporting rod. I
