Philadelphia, Pa., a. vania Application July 22,

8 Claims.

This invention relates to Jacquard loom harness, and it relates more particularly to improved means for attaching a lingo to the lower end of a jacquard heddle.

Heretofore various means have been devised or suggested for attaching lingoes to the lower ends of the heddles in Jacquard loom harness. None of these have been entirely satisfactory, principally by reason of the wear which occurs at the eye of the lingo on account of the lingo swinging with respect to the lower end of the heddle during the operation of the loom, and also by reason of the fouling of the harness at the point of connection of the lingo to the heddle which frequently occurs and which causes imperfections in the woven pattern.

The principal object of the present invention is to provide a simple, efficient, yet inexpensive, means for attaching a lingo to the lower end of the heddle.

A further object of the invention is to provide a device by means of which lingoes with worn eyes may be readily and expeditiously replaced.

A further object of the invention is to provide improved means for attaching lingoes to heddles in such manner that wear will be reduced to a minimum.

With the foregoing objects in view, this invention contemplates the provision of a novel form of lingo attaching member and a suitable formation of the lower end of the heddle, whereby said attaching member may be quickly and conveniently mounted on the heddle and which when so mounted will be fixedly and rigidly attached thereto.

The nature end characteristic features of the invention will be more readily understood from the following description, taken in connection with the accompanying drawing forming part hereof, in which:

Figure 1 is a front elevation of a Jacquard loom heddle having a lingo attached thereto by means embodying the main features of the present invention;

Fig. 2 is a side elevation thereof;

Fig. 3 is an enlarged fragmentary detail view illustrating the structure at the point of connection of the upper end of the lingo to the lower end of the heddle;

Fig. 4 is a perspective view of the portion of the structure illustrated in Fig. 3;

Fig. 5 is a perspective View of the lower end of the heddle, suitably perforated for the reception of the connecting device;

Fig. 6 is a perspective view of one of the concorporation of Pennsyl- 1936, Serial No. 91,814

necting devices detached, in the form assumed before the same is mounted onthe lower end of the heddle for the purpose of attaching the lingo thereto; and

Fig. '7 is a perspective view of the upper end of a lingo of an ordinary type adapted to be attached to the lower end of the heddle.

It should of course be understood that the drawing and description herein are illustrative merely and that various changes and modifications may be made in the structure disclosed without departingfrom the spirit of the invention.

Referring to the drawing, in the particular embodiment of the invention therein shown, in is a jacquard heddle preferably made of a strip of thin flat metal. This strip is provided at its upper end with an eye H for the attachment of the usual control cord (not shown) of the jacquard mechanism. The heddle is also provided with the usual warp eye l2 intermediate the ends thereof.

The lower end of the heddle is provided with a plurality of openings I3, I4 and I5 punched therein. The opening l3 nearest the lower end of the strip is preferably somewhat longer than the openings 14 and I5 for a purpose to be presently explained.

The lingo may be of the ordinary form comprising a rod i6 having its upper end flattened as at IT, and provided in said flattened portion with an eye l8 for the attachment of the lingo to the heddle.

The device for attaching the lingo to the heddle comprises a peculiarly shaped clip 20 shown in detached perspective in Fig. 6, and preferably made from a thin, narrow strip of metal; the strip being substantially equal in width to the width of the openings l3, I4 and [5 in the lower end of the heddle. The strip is bent and formed to provide an eye portion 2| approximately circular in conformation from which two legs 22 and 23 extend upwardly.

One of these legs, 22, which is substantially shorter than the other, extends, in the operative condition of the device, upwardly as at 24 along one face of the lower end of the heddle, and thence passes through the opening l3 nearest the lower end of the heddle, thence extending as at 25 along the other face of the heddle to the next opening 14 through which it passes, having its end 26 bent over upon the face of the heddle along which it first extends.

The other leg 23 of the clip 20 extends upwardly from the eye portion 2|, along the opposite face of the lower end of the heddle as at 21 until it reaches the point where the portion 25 of the leg 22 is disposed on that face of the lower end of the heddle. At this point, the leg 23 is offset as at 28 so as to clear the portion 25 of the leg 22. The upper end of the leg 23 bears as at 29 against the face of the lower end of the heddle, and thence extends through the opening I5 therein, having an end portion 30 bent downwardly on the other face thereof (see Fig. 3).

The clip 20 is initially formed in the condition shown in Fig. 6 of the drawing, having the leg portions 22 and 23 flaring with respect to each other. When it is desired to use the same for connecting a. lingo to the lower end of the heddle, the eye portion of the lingo is first passed over one of the legs of the fastening device until it is positioned within the eye portion I1 thereof. The shorter leg 22 of the clip 20 is then inserted through the elongated opening [3 of the lower end of the heddle, then turned over to permit the end portion 26 thereof to be passed through the opening It, simultaneously passing the bent over end portion 30 at the upper end of the longer leg 23 through the aperture IS in the lower portion of the heddle. The end portions 26 and 30 of the legs of the clip 20 are then bent down to the positions shown in Figs. 1 to 4 of the drawing.

It will be noted that in the foregoing arrangement, the fastening device is so mounted that there will be no movement thereof with respect to the lower end of the heddle, and further that by reason of the foregoing, there will be little likelihood of the heddles and lingoes fouling on each other when the shedding takes place.

By reason of the rigid connection of the attaching device to the lower end of the heddle, wear on the eye of the lingo will be considerably reduced, yet, on the other hand, in the event of excessive wear on the eye portion of the lingo, or even excessive wear on the eye portion of the attaching device, renewal of these parts may be readily effected by merely bending up the bentover end portions 26 and 30 of the legs of the attaching device, whereupon the attaching device may be readily removed from the lower end of the heddle to permit unworn parts to be substituted.
