entran -stare Ar I titers JOHN JACOB KAUFMANN, F ELKINS PARK, PENNSYLVANIA, ASSIGNOR T0 STEEL HEDDLE MANUFACTURING COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A COB- IPORATION or rnNNsYLvANLe' COMBINED HEDDLE AND LrNeo ANnr/rr'rnon or MAKING THE SAME Application filed June 24,

My invention. relatesto combined heddles and lingoes and the method of making the same, and it relates more particularly to the.

manner of connecting the lingo to the heddle whereby thereis produced a composite article particularly adaptable for use in Jacquard looms and the like.

Heretofore, in the use of Jacquard loom harness, diificulties have been encountered at the point of attachment of the lingo to the heddle.v By reason of the relative movement between the lingo and the eye usually provided at the lower end of the heddle, wear occurs at this point, andin course of time either the eye of. the heddle or the corresponding, portion of the lingo will be worn through, and the lingo thereby become detached. In other instances, the lingoes be-- come ,unhooked from the heddles during the manipulation of the same, and in other instances the free actuation of the heddles is interfered with by reason of enlargements at the point. of attachment of the lingo to the heddle.

The object, therefore, of the present invent-ion is to provide a' combined heddle and lingo in which possibility of the lingo becomingdetached from the heddle,either by wear or by becoming unhooked during themanipulation of the harness," will be eliminated. A further object of the invention is to provide such a device in which projections at the point of attachment of the lingo to the heddle will be reduced to a minimum. A further object of the invention is to provide an improved process of making a combinedheddie and lingo whereby the samew'ill-be relatively inexpensive and easy to. assemble.

WVith the foregoing objects inview, my inventioncontemplates the provision offa jacquard heddle made-of thin, flat metal or wire, at the lower end of which a lingo, is permanently attachedin a simple, efficient and inexpensive manner. I I

The nature and characteristic features of my invention will be more readily understood from the following description, taken in con- Figure l is a front elevation ofa combined 1927. Serial No; 201,054.-

Fig. 3 is a perspective view of the end portions of the heddle and lingobefore being attached to each other; I,

Fig. 4 is a similar view with the parts engaging each other at an intermediate stage 'of the method; and

Fig. 5 is a similar View with said parts at the finished or completed stage of the method.

Referring to the drawings, in the particular embodiment of my invention therein shown, 6 is a jacquard heddle, preferably made of thin, flat metal or wire, having an eye 7 at the upper end for the attachment of the control cord of the jacquard mechanism; a warp eye 8 intermediate the ends thereof; and an eye 9 at the lower end thereof'for theattachment of thelingo 10, V

In the fabrication of the device, the end of the lingo 10 is first flattened as at 11, and in the flattened portion 11 there is provided a slot 12. There is also provided a slit 13 ere tending from the middle portion of the slot 12 through one of the side walls of the flattened portion 11. The lower end of the heddle 6, beyond the eye portion 9, is provided with an extension 14 of such length as to fill the eye portion 9 of the heddleto be inserted through said slit 13.

- .Theparts being initially shaped as aforesaid, the eye portion 9 of the heddle 6 is now brought into engagement with the flattened portion 11 of the lingo .10, by inserting one of the side shanks of the eye portion 9 of the heddle through the slit 13, the heddle be- "ing disposed at right angles to the lingo while being so inserted, after which the bed die is brought into alinement with the lingo 10, the parts then being in the position shown in Fi g. of the drawings. The flattened portion 11 of the lingo is now subjected to a pressing or swaging operation portion it of the heddle l6 and hold the same lingo in the operation of the loom.

to cause thesame to be shaped as shown in Figs. 1, 2 and 5 of the drawings, wherebythe sidewise extensions of the flattened portion 11 are reduced to the initial dimensions of the cross section of the, lingo, and at the same time the slot li in the flattened portion wiil be reduced, thereby to grip firmly the end against movement therein. At the same time, the slit 13 in one of the side walls of the flattened portion 11 of the lingo 10 will be closed as shown in Figs. 2 and 5 of the drawings.

In this manner, there will be produced a; combined heddle and lingo in which relative movement between the lingo and theheddle will be eliminated, thus obviating wear at this point, as well as efiectlvely prevent ng the accidental disconnection of the lingo from the heddle.

lt will also be noted that the sidewise "projections in the lingo, usually found at the point of attachmentto the heddle, will be eliininated,'thus permitting great or ease of movement of the heddle and the bed the nature and char- Having thus deseri acteristic features of my invention, what I.

claim as new and desire to secure by Letters Patent, is:

1. A heddle having an eye near the lower end thereof, and a lingo comprising a rod having a slot at its upper end within which the lower end of theheddle is fixedly positioned, the slotted portion of the lingohaving rigid side walls closely. engaging and gripping the lower portion of the heddle.

2. A heddle made of thin fiat metal or wire having an eye near the lower end thereof, and a lingo comprislng a rod having a slot at its upper end within which the lower end oi the heddle is fixedly positioned, and the slotted portion of the lingo having rigid side walls closely engaging and grippingthe lower portion ofthe heddle.

3. A heddlev made of thin flat metal or wirc having an eye near the lower end there:

of and a portion projecting below said eye, and a lingo comprising a rod having a slot at its upper end within which thelower end g, of the heddle is fixedly positioned, and'the slotted portion of the lingo having rigid side walls closely engaging and gripping the portion of the heddle below the eye.

at. A heddle made of thin fiatmetal or wire having an eye near the lower end thereofand a portion projecting below said eye, and a lingo comprising a rod-having a flat portion at its upper end, said flat portion having a slot within which tlielower end of "having an eye near the lower end thereof the heddle is fixedly positioned, and the side '1 walls of the slotted portion of the lingo'engaging and gripping the portion of the bed dle below the eye.
