United States Patent O LOOM HARNESS John J. Kaufmann, Jenkintowm'Pa., assignor to Steel Application July 23, 1954, Serial No. 445,389

Claims. (Cl. 139-92) This invention relates to loom harness, and it relates more particularly to the construction and arrangement of the loom harness frames in which are mounted the heddles used for shedding the warp.

Heretofore, in those loom harnes frames in which the heddles were mounted on rods extending from end to end in the frames, various means were employed for supporting and securing the ends of the heddle rods. In the form most commonly used, the ends of the rods were passed through slots in the end struts of the frame and spring hooks were provided on the outside of the end struts, which spring hooks had bent over end hook portions engaging apertures Vin the projecting ends of the heddle rods.

In the construction and arrangement above described there were objectionable parts projecting on the outside of the end struts of the heddleframes which were a constant source of danger to the loom operators.

Various attempts have been made to provide means for supporting and securing the ends of the heddle rods, disposed on the inner faces of the end struts, but such arrangements involved new and diiferent complications and such devices were not entirely satisfactory.

The principal object of the present invention is to provide improved means for mounting, in a loom harness frame, the heddle rods with the heddles thereon, all the parts of which will be disposed inside the end struts of the harness frame. Y

A further` object of the invention is to provide improved means, of the character aforesaid, for supporting and securing the ends of the heddle rods in the frame which will permit the expeditious mounting in the frame of the heddle rods with the heddles thereon, and which will permit the ready removal of the rods, or the displacement of the end portions thereof, for the purpose of rearrangement of the heddles on the rods, or for the addition of heddles on the rods, or for the removal of heddles therefrom, whenever the same becomes necessary by reason of a change in the character of the cloth to be woven, or for replacement or repair.

A further object of the invention is to provide means of the character aforesaid, which will permit the frames to be made rugged in` construction, and in which the parts will be resistant to wear.

The nature and characteristic features of the present 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 loom harness frame having novel means, embodying the main features of the present invention, for supporting and securing the ends of the heddle rods therein;

Fig. 2 is a fragmentary elevational view of a corner portion of said frame on an enlarged scale;

Fig. 3 is a vertical section taken on the line 3-3 of Fig. 2; and y Fig. 4 is a similar section taken on the line 4-4 of Fig. 2.

2,827,079 Patented Mar. 18, 1958 It should, of course, be understood that the description and drawing herein are illustrative merely, and that various modifications and changes may be made in the structure disclosed without departing from the spirit of the invention.

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

Referring to the drawing, the heddle frame therein shown may comprise top and bottom rails or shafts 10, connected at their ends by end struts 11, each comprising primarily an outer strip 12 and an inner strip 13. The end portions 14 of each outer strip 12 are bent over and secured to the outer marginal edges of the rails 10 by screws 15, whereas, the end portions of the inner strips 13 are bent inwardly as at 16 and are secured to the inner edges of the rail 10 by screws 17.

A portion of each inner strip 13 adjacent each bent in portion 16 thereof is spaced from the outer strip 12, and into the space thus provided, there projects one end 18 of an angular member, a portion 19 of which extends across the end of the, rail 10, and another portion 20 of which is bent over and is disposed between the bent over portion 14 of the outer strip 12 so as to be held in place by the screws 15 which secure the bent over portions 14 to the outer edges of the rails 10.

In the portion 18 of the angular member and in a corresponding registering location in the inner strip 13 of each end strut there is provided a recess 21 open to one side for the reception of one end of one of the heddle rods 22 upon which the heddles 23 are mounted.

There is also provided in connection with each of the end struts 11 and on the inside thereof, a strip 24, the ends of which are spaced inwardly from the end portions of the inner strip 13 of the end struts 11, to provide spring tongues 25 the ends of which are provided at the proper location with recesses 26, also open to the same side as the recesses 21 hereinbefore referred to.

Each of the spring tongues 25 may also be provided, within the recess 26 with a T-shaped portion, the head part 27 of which is adapted to pass through an aperture 28 in the end of the heddle rod 22, which aperture has a wide portion 29 through which the head part 27 may pass, and a narrow portion 30 in which the narrow portion 31 of the T-shaped portion of the spring member is normally positioned to hold the end of the heddle rod 22 in the recesses hereinbefore referred to. (See Figs. 2 and 3.)

The end of each spring tongue 25 is preferably provided with a bent over portion 32 to facilitate the manipulation of the spring tongue 25 when it is desired to place the end of a heddle rod 22 in position in one of the recesses 21.

The portion 19 of the angular reinforcing member is secured to the outer strip 11 of the end strut by rivets 33. Likewise, the portion 18 of each angular member is secured by a rivet 34 where the same extends between the outer strip 12 and the inner strip 13. Also, the inner and

outer strips

12 and 13, and the central portion of the strip 24, which provides the spring tongues 25, are secured to each other by rivets 35. By means of the foregoing the end struts are greatly stitened against bending and ilexure.

The spring tongues 25 are normally tensioned so as to stress the heddle rods 22 from end to end, and also to insure the securing of the ends thereof in the recesses 21.

The manipulation of the parts in the mounting of the heddle rods in the frame, or the removal of the same therefrom, is relatively simple, it being only necessary to ex the spring tongue 25 at a particular corner where the heddle rod is to be'removed, whereupon the head 27 of ICE the T-shaped portion of the spring member may be passed through the wide portion 29 of the aperture 28 and the end ofghe heddle rod.may then berernovedfrorn the recess 21'1'nliwhenlitisdsiredlto replace 'particular'endof a heddle rod, the 'reverse'procednre will," off'cours'e', be fcuwd... t
