`Patented Jan. 7, 1936 PATENT oFFicE v LOOM HARNESS Y' John Jacob Kaufmann, Elkins Park, Pa., assignor` f to ASteel Heddle Manufacturing Company, Philadelphia, Pa., a corporation of Pennsylvania Application February 16, 1934, Serial No. '711,483

1.0 Claims. (C1. 139-91) lVIy invention relates to loom harness, and it relates more particularly to improved means for mounting in a loom, groups of heddles for controlling the Warp ends of the selvage, although it will of course be understood that the harness may be used for other purposes, such for instance as Weaving stripes in a fabric, in which the warp ends thereof are manipulated independently of the ends controlled by the main harness frames.

Heretofore in the mountingof small groups of heddles in a loom for the purposes aforesaid,

the arrangement most commonly used comprised the provision oi relatively short supporting bars upon which the heddles were mounted, .which in turn were connected to the actuating straps by means of unitary hook members. One of the principal diflicultiesencountered With this arrangement Was that the relatively shortsupporting bars, upon which the heddles were mounted, would become tilted irom their proper horizontal positions, causing the heddles to be crowded toward one side, and thus causing inequalities in the Weave.

The principal object of my present invention is to -provide loom harness for controlling :relativelysmall groups of heddlesior selvagevvorkand the like, Which vvill be simple, durable and eiiicient, which Will be inexpensive in construction, and in which the heddle supporting bars will at all times be maintained horizontal, so that the heddles mounted thereon will be properly supported and improper crowding of the warp thereby prevented.

'I'he nature and characteristic features of my invention will be more readily understood from the following description, taken in connection with the accompanying drawing forming part hereof, in which: I

Figure 1 isa front elevational view of a heddle supportingdevice embodying the main features of my present invention; Y

Fig. 2 is an enlarged fragmentary elevationalv view of the upper portion of the structure shown in Fig. l; Y

Fig. 3 is a side elevational view of the portion of the structure shown in Fig. 2; y

Fig. 4 is a vertical section taken approximately on the line 4--4 of Fig. 2; andv Fig. 5 is a perspective view illustrating, in detached relationship, certain of the parts of the I structure.

It will, of course, be understood that the description and drawing herein contained are illustrative merely, and that various modifications and changes may be made in the structure diS closed Without departing from the spirit of my invention.

`Referring to the drawing, in the particularV embodiment of my invention therein shown, Ill are the heddles, Which may be of any preferred type but which are shown as made of a thin flat strip of metal or wire in which a central Warp eye II of the ordinary type is provided. Each of the heddles Ill is also provided at its ends with mortises I2, for mounting the same on the heddie supporting bars.

The heddle supporting bars consist of relative-` ly short members I3, punched andformed from metallic strips, and provided with perforations I4 near the ends thereof for a purpose to be presently explained. The end portions ofthe heddle supporting bars are reduced in Width, thereby providing shoulders I5 for a purpose to be presently explained.

One heddle supporting bar is provided at the top, and another at the bottom of the structure, and connecting said bars are side members I6, also made of thin flat strips of metal or Wire preierably somewhat stiffer and heavier, however, than the Wire from which the heddles I are formed. Near each end of each of the side members I6 there is provided a slot I'I complemental to the reduced end portion of the bar I3, upon which it is mounted. The arrangement is such that when the side members IB are mounted with the slots Il thereof engaging the reduced end portions of the bars I3, the inner faces of said side members I6 adjacent the slots -I1 Will abut against the shoulders I of said bars.

'I'he side members I6 are maintained on the bars by means of the looped end portions I8 of a bail member I9, which extend through the apertures I4 in the reduced end portions of the bars I3, and when so mounted serve to 'hold the side members I6 in proper position against the shoulders I5 of the Ybars I3, so that skevving of said bars will be prevented When the various parts are assembled.

The central portion of the bail member IQ is V-shaped, terminating in a central apex 20, at which point said bail member is engaged by the looped end portion 2| of a hook member 22. The other end of the hook member 22 is shaped in the usual hook formation, as at 23, for engagement in the apertures provided in the actuating strap (not shown).

`It Will benoted that the portion of the hook member 22 which engages the actuating strap comprises a single piece of wire, so that the apertures in the actuating strap may be made as small as possible, instead of being abnormally large with respect to the Width of the strap, as they are when hook members of the present type are used, which are made in unitary form with a double thnckness of Wire at the point Where the strap is engaged.

Furthermore, the provision of the bail member I9 and the hook member 22 in looped engagement therewith, permits the maintenance of the supporting bars I3 and side members it in proper relationship, as any tendency toward distortion will be eliminated by the free pivotal connection between the hook member and the bail member.

I claim:

1. In a loom harness for supporting small groups of heddles, heddle supporting bars at the top and bottom thereof, a one piece bail member at the top and another one piece bail member at the bottom, each of said bail members having end portions engaging the end portions of the respective supporting bars and means in free pivotal engagement with the bail members for connecting said bail members to the actuating straps.

2. Ina loom harness for supporting small groups of heddles, heddle supporting bars at the top and bottom thereof, bail members having looped end portions extending through apertures in the end portions of the supporting bars, and means in free pivotal engagement with the bail members for connecting the said bail members to the actuating straps.
