BY @M 6 ATTORNEY HEDDLE FRAMES H,- a n H n g m a l y, m, gn to Dan, a corporation of Pennsylvania Application December 9, 1954, Serial No. 474,064

4 Claims; (Cl; 139-92) This invention relates to heddle frames, and it relates more particularly to improved means for securing and supporting the ends of the heddle supporting rods in the frames.

Heretofore, various means for supporting and securing the ends of heddle supporting rods have been suggested, and many of these have been found to be satisfactory under certain conditions, and in connection with certain types of frames.

However, the means heretofore employed for securing and supporting the ends of the heddle supporting rods in the frames were, in most instances, difiicult to manipulate whenever it was desired to release the ends of any of the rods or to entirely remove the heddle assemblies from the frames. I

The principal object of the present invention is to provide, in loom heddle frames, improved means for supporting and securing the ends of the rods upon which the heddles are mounted, whereby wear will be reduced to a minimum.

A further object of the present invention is to provide a heddle frame with means for supporting and securing the ends of the heddle supporting rods whereby any of the ends of said rods may be quickly and easily detached from the frame at the ends thereof for the purpose of adding or removing heddles on the rods.

A further object of the present invention is to provide improved means, of the character aforesaid, whereby the heddle assemblies may be quickly and easily re moved from a heddle frame and replaced therein when desired for any purpose.

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 I having therein means embodying the main features of the present invention for supporting and securing the ends of the heddle supporting rods;

Fig. 2 is an enlarged fragmentary detail view of a portion of one of the corners of the frame;

Fig. 3 is a vertical section taken on the line 3-3 of Fig. 2;

Fig. 4 is a horizontal section taken approximately on the line 4-4 of Fig. 2; and

Fig. 5 is a perspective view of the principal novel portions of a device embodying a preferred form of the invention detached.

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, there is therein shown a preferred form or embodiment of the invention, in which the heddle frame proper comprises top and bottom rails connected at their ends by struts 11. The end struts 11 may each comprise a pair of

metallic strips

12 and 13,

Steel Heddle Manufacturing Company, Philadelphia,

United States Patent 2,722,949 Patented Nov. 8, 1955 2 the ends of which" are bent over as at 1'4 and 15 respectively, and secured by fastening screws 16' to the ends of the rails 1'0.

' The-heddlesupporting rods 17, upon which the heddles 18 are mounted in the usual manner, are made of strips of flat metal, preferably spring steel, or other material havingthe requisite characteristics to operate in the manner to be presently explained.

The end portions of the heddle supporting rods 17 preferably terminate. within the inner faces of the inner strips 1 2 of the end struts 1 1, and each end portion of each heddle rod is slotted as at 19, whereby the ends of the heddle rod 17 are bifurcated to provide

spring legs

20 and 21.

In the form of the invention shown, at each corner of the frame there is also provided a bracket member 22, preferably made from a strip of flat metal similar to that of which the

strips

12 and 13 of the end struts 11 are made.

Each of the bracket members 22 is bent to provide a horizontally extending portion 23 which is secured to an end of the rail 10 by the screws 16 which are used to secure the bent in end portion 14 of the strip 12 of the end strut 11 at each corner of the frame.

Each of the bracket members 22 also has a vertically extending portion 24 preferably located a short distance from the inner face of the inner strip 12 of the end strut 11. In the vertically extending portion 24 of each bracket 22 there is provided a recess 25, open at the side, and having an upwardly extending leg 26 on the open side to provide a pocket for the reception of the tongue 21 of the end of a heddle supporting rod 17, whereas at the upper end of the recess 25, in the vertical portion 24 of the bracket member 22, there is provided a tit 27 which serves to retain the tongue 20 at the end of the heddle supporting rod 17.

The foregoing arrangement is such that the ends of the rod 17 may be readily inserted and removed from the recesses 25 in which they are normally supported by springing the same past the tits 27 at the end of the recesses 25 in which said tits 27 are located.

The innermost end of the vertical portion 24 of each bracket member 22 is bent outwardly as at 28 and is provided with a lug 29 at its end, which is seated in a slot 30 provided in the inner strip 12 of the end strut 11.

It will be noted that by the foregoing arrangement there is provided a novel means for supporting and securing the ends of the heddle supporting rods in heddle frames so constructed and arranged that any of the end portions may be quickly and easily disengaged from the bracket members or if desired all of the ends of the heddle rods may be readily removed from the brackets for the purpose of removing the entire heddle assembly from the frame.

It has been found in practice that, by reason of the resiliency of the ends of the heddle supporting rods, as hereinbefore described, wear will be reduced to a minimum at the places of engagement of the ends of the beddle rods with the supporting structure.

I claim:

1. In a heddle frame having longitudinally extending rods upon which the heddles are mounted, the means for securing and supporting the ends of said heddle rods in the frame which consists in providing, at each corner of the frame, an open side recess, and the end of the heddle rod being slitted to provide spring tongues whereby said end of the heddle rod may be snapped into and out of said recess, and means serving normally to retain the end of the heddle rod in the recess.

2. In a heddle frame having longitudinally extending rods upon which the heddles are mounted, the means for securing and supporting the ends of said heddle rods in the frame which consists in providing a. member at each corner of the frame having an open side recess, said member having a leg extending partway across the open side of the recess, and also having a tit at the other end of the recess, and the end of the heddle rod being slitted to provide spring tongues'whereby said end of the heddle rod may be snapped into and out of said recess, the aforesaid leg and tit serving normally to retain the end of the heddle rod in the recess.

3. In a heddle frame having longitudinally extending rods upon which the heddles are mounted, the means for securing and supporting the ends of said heddle rods in the frame which consists in providing, at each corner of the frame, a bracket member having an open side recess, said bracket member having a leg extending part way across the open side of the recess, and also having a tit at the other end of the recess, and the end of the heddle rod being slitted to provide spring tongues whereby said end of the heddle rod may be snapped into and out of said recess, the aforesaid leg and tit serving normally to retain the end of the heddle rod in the recess.

4. In a heddle frame having longitudinally extending rods upon which the heddles are mounted, the means for securing and supporting the ends of said heddle rods in the frame including parts having recesses in which the ends of the heddle rods are normally positioned, and the ends of the heddle rod being slitted to provide integral spring tongues at said ends of the heddle rod, and means serving normally to retain the ends of the heddle rod in the recesses.
