LOOM HARNESS Filed Sept. 26, 1956 ATTORNEY United States 7 Patent "ice Heddle Manufacturing Company, Philadelphia, Pin, a corporation of Pennsylvania Application September 26, 1956, Serial No. 612,293

Claims. (Cl. 139-92) This invention relates to loom harness, and it relates more particularly to improved means, in a loom harness frame, for supporting and securing the ends of the rods upon which the heddles are mounted in the frame.

Heretofore devices of various forms have been used in loom harness frames for the purpose of supporting and securing the ends of the rods upon which the heddles are mounted.

However, while it was long recognized that it was advisable, principally for safety, as well as for other reasons, to keep the outer faces of the end struts of the frames free from projections and parts which might catch the hands of the weavers, as well as becoming fouled on other objects, it proved to be quite difficult to provide satisfactory supporting and securing devices in which all of the parts were mounted on the inside of the frames.

The principal object of the present invention is to provide, in a loom harness heddle frame, improved means for supporting and securing the ends of the heddle rods, which means are disposed entirely within the interior of the frame.

A further object of the present invention is to provide a device, of the character aforesaid, which is so con structed and arranged that the ends of the heddle rods may be readily disengaged and easily removed from the supporting and securing devices.

A further object of the present invention is to provide a device, of the character aforesaid, which, while inexpensive in construction, will be very eifective in its operation and for its intended 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 heddle frame provided with devices for supporting and securing the ends of the heddle rods, said devices embodying the main features of the present invention;

Fig. 2 is a perspective .view of a corner portion of a heddle frame illustrating more particularly the construction and arrangement of one of the devices of the present invention, the heddle rod being shown in dotted lines;

Fig. 3 is an enlarged detail elevational' view of a corner portion of a heddle frame with a device of the present invention mounted therein;

Fig. 4 is a horizontal section taken on the line 4 -4 of Fig. 3;

Fig. 5 is a front elevation of the member for securing and supporting one end of a heddle rod, detached; and

Fig. 6 is a side elevation thereof.

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 and arrangement shown without departing from the spirit of the invention.

Referring to the drawing, the heddle frame proper may be of any preferred construction, for example, as shown the same may comprise top and bottom rails 1t), con- 2,896,672 Patented July 28, 1959 nected by end struts each of which may consist of two juxtaposed metallic strips 11 and 12, respectively, the ends of which may be bent at right angles, as at 13 and 14, respectively, and secured to the inner and outer edges of the top and bottom rails 10 in the usual manner.

The heddle supporting rods 15 may be of any preferred type, preferably comprising strips of fiat metal which extend from end to end of the frame. The ends of the heddle supporting rods 15 are preferably terminated a short distance from the inner faces of the inner metallic strips 11 of the end struts of the frame.

The heddles 16 are slidably mounted on the heddle rods 15 in the usual manner, and it will. be apparent that the device of the present invention is applicable to various types of heddle frames, and for the securing and supporting of various types of heddles rods in such frames.

Each of the heddle rods 15 is provided near each end with an aperture 17 adapted to be engaged by a portion of the supporting and securing device as will be hereinafter more fully set forth.

The supporting and securing members 18 of the, present invention are each made from a thin flat strip of metal punched and formed as hereinafter set forth, and made of spring metal so as to provide the requisite tension of the heddle rods 15.

The innermost end of each of the supporting and securing members 18 is secured to the strips Hand 12, which form the end struts of the frame, by means of a rivet 19 extending therethrough, and the portion of the member 18 which extends beyond the rivet 19 is provided at its end with a bent over projection or lug 20 which extends into a complemental slot 21 provided in the strip 11 of the end strut, thereby to prevent rotation of the member 18 about the rivet 19.

The free end of each member 18. is also provided with a projecting lug 22 which extends into a complemental slot 23 in the bent over portion 13 of the strip 11 of the end strut, which also serves to prevent sidewise movement of the member 18. The lug 22 has a limited range of movement in the slot 23 in a direction lengthwise of the frame.

Intermediate the ends of the supporting member 18 the same is cut out to provide two recesses 24 and 25 with a projecting portion 26 therebetween. The end of the projecting portion 26 is bent over to provide a lip 27, which lip extends from one side face thereof.

The projecting portion 26 of the member normally extends through the aperture 17 in the end of the heddle rod 15 which is supported by the member 18, and the lip 27 thereof serves to prevent undesired separation of the ends of the heddle rods from the supporting members 18.

as to free the projecting portion 26 from engagement with the end marging of the aperture 17, and to retract the lip portion 27 toward the center of the frame, whereupon the end of the heddle rod 15 may be pushed aside to free the same from the supporting and securing member 18.

When the tension is thus released at one end of the heddle rod 15, the other end of the said rod may be easily removed from its supporting and securing member 18, and when the heddle rods 15 at both the top and bot tom frames are thus released, said heddle rods with the heddles thereon may be removed as a unit from the frame.
