LOOM HARNESS Filed Nov. 29, 1965 uwzwr'on FRANK h. m U/MA IVA/ ATTORNEY United States Patent 3,362,437 LOOM HARNESS Frank H. Kaufmann, Huntingdon Valley, Pa., assignor to Steel Heddle Manufacturing Company, Philadelphia, Pa., a corporation of Pennsylvania Filed Nov. 29, 1965, Ser. No. 510,345 6 Claims. (Cl. 139-92) ABSTRACT OF THE DISCLOSURE Heddle frame for looms having the heddle supporting rods extending at their ends into the side struts of the frame, the heddle rods being slidably mounted intermediate their ends for sidewise insertion and removal with locking pins preventing sidewise displacement, the heddles being freely movable on the heddle rods to the side struts.
This invention relates to heddle frames for looms and it relates more particularly to improved means for securing and supporting the ends of the heddle supporting rods in the frames.
Various means for supporting and securing the ends of heddle supporting rods have heretofore been suggested, and many of these have been found to be satisfactory under certain conditions, and in connection with certain types of frames.
The means heretofore employed for securing and supporting the ends of the heddle supporting rods in the frames, in many instances, reduced the available space between the side struts for the reception of the heddles so that full utilization of the width of the heddle frame was not possible. In other instances difliculties were encountered in manipulating the securing and supporting structure for insertion and removal of the heddle supporting rods while still retaining freedom of movement of the heddles from one side to the other of the heddle frame.
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 and with which the full width of the harness frame can be effectively utilized.
It is a further object of the present invention to provide a heddle frame with meansfor supporting the ends of the heddle supporting rods whereby the ends of said rods may be quickly and easily detached at the ends thereof for the purpose of adding or removing heddles on the rods, and which requires only a simple manipulation of the heddle supporting rod for locking or unlocking It is a further object of the present invention to provide a heddle frame with the heddle supporting bars free rom obstructions at the ends thereof so that free movement of the heddles along the heddle bars can be effected over the entire lengths of the heddle bars, and which can be utilized in heddle frames having pairs of heddle supporting rods at their upper and at their lower ends.
It is a further object of the present invention to provide a heddle frame with the heddle supporting bars free from obstructions at the ends thereof and with additional space for freedom of movement of the Warp carrying eyes of the heddles on the heddle bars while providing ease of insertion and removal of the heddle supporting bars.
It is a further object of the present invention to provide a heddle frame in which each of the heddle supporting bars has an improved resilient lock utilizing the resilience of the heddle supporting bars for this purpose.
Other objects and advantageous features of the invention will be apparent from the description and claims.
The nature and characteristic feature 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:
FIG. 1 is a front elevation of a loom harness frame 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 a fragmentary vertical sectional view, enlarged, taken approximately on the line 2-2 of FIG. 1;
FIG. 3 is an exploded perspective view as taken from the opposite side from that of FIG. 2;
FIG. 4 shows in an enlarged fragmentary vertical sectional view one embodiment of the invention as applied to a pair of heddle supporting rods; and
FIG. 5 is a view similar to FIG. 4 showing another embodiment of the invention as applied to a pair of heddle supporting rods.
It should, of course, be understood that the description and drawings herein are illustrative merely, and that various modifications and changes can be made in the structure disclosed without departing from the spirit of the invention.
Referring to the drawings, there is therein shown a preferred form of embodiment of the invention, in which the heddle frame proper comprises top and bottom rails 10 connected at their ends by struts 11. The top and bottom rails 10 are preferably made of hollow extruded shapes of aluminum or magnesium alloys, with an inwardly extending longitudinally disposed flange portion 12.
The struts 11 can be of any desired construction and of any preferred material but as shown are preferably of compressed wood, with cut outs 13 at each end to provide extended central lengths 14 of the struts 11 of lesser width than the ends, thereby to add to the available interior space therebetween.
The struts 11 can be secured to the top and bottom rails 10 in any desired manner, such as by screws 15.
The struts 11 at spaced locations and at predetermined locations above and below the lower margins of the flange portions 12 have aligned openings 16 for the reception of the ends of heddle supporting rods 17. The rods 17 preferably each has a longitudinal groove 18 along one face thereof and are capable of being resiliently bent or sprung, as hereinafter pointed out, without permanent distortion.
The rods 17 have slidably mounted thereon heddles 19 of any desired type, but preferably like those shown in FIGS. 2 and 3 of Patent No. 2,047,511, and with warp eyes 20 intermediate their ends.
The flange portion 12 inwardly of one end of the top and bottom rails 10 have at one or more predetermined locations therealong key blocks 21 preferably T-shaped in vertical cross section secured by rivets 22 to the flange portion 12 and with head portions 23 and reduced shank portions 24. The thickness of the head portions 23 is preferably the same as or slightly less than the depth of the grooves 18 so that the head portions 23 do not obstruct the free movement of the heddles 19 from end to end on the heddle rods 17.
The heddle rods 17, at predetermined spaced locations, have horizontal key hole slots 25 with enlarged portions 26 to permit of the passage of the head portions 23 and portions 27 for the reception of the shank portions 24 with the head portions 23 preventing displacement of the rods 17 out of the main plane of the heddle frame.
In order to retain the heddle rods 17 from longitudinal movement while their ends are in the openings 16 in the struts 11 each heddle rod 17 has at a predetermined distance from one end a locking aperture 28 with which a pin 29 carried by the flange portion 12 is in engagement. The pin 29 preferably has an enlargement or collar 30 providing a shoulder which holds the rod 17 in spaced 3 relation from the flange portion 12 thereby obviating any binding of the heddles 19.
When it is desired to remove a heddle rod 17 for mounting of heddles 19 thereon or for removing heddles 19 therefrom, the heddle rod 17 at the pin 29 is flexed or sprung so as to be clear of the pin 29. The heddle rod 17 can then be initially moved longitudinally to bring the enlarged portions 26 to the head portions 27, thus permitting separation of the heddle rod 17 from its retention by the key blocks 21 and complete removal, the heddle rods 17 being slidable in the openings 16 for this purpose. The heddle rod 17 can be inserted by a reversal of the operation just described.
In FIG. 4 the invention is shown applied to a heddle frame similar to that described above but having a longitudinally disposed flange portion 12 with heddle rods 17 along both sides thereof each with a locking aperture '28. The pin 29a is mounted on the flange portion 12 and has an enlargement or collar portion 30a providing shoulders on both sides of the flange portion 12 to hold the heddle rods 17 as before.
In FIG. 5, the pin 29b is shown as of substantially uniform diameter and accordingly does not limit the inward horizontal movement of the heddle rods 17 with respect to the flanged portions 12 in the same manner as do the pins 29 and 29a.
It will be noted that the heddle rods 17 are held against longitudinal movement with their ends in the openings 16 and with free movement permitted of the ends of the heddles 19 along the heddle rods 17. The warp eyes 20 by reason of the formation of the side struts 11 have even greater freedom of sidewise movement.
By the foregoing arrangement there is provided a simple but effective mounting for the heddle rods 17 with freedom of movement of the heddles 19 and increased capacity both at the ends and at the warp eyes. The insertion and removal of the heddle rods 17 may be readily effected, by a simple manipulation while during use the heddle rods 17 are adequately supported and held against displacement.
I claim: 1. In a heddle frame having horizontal top and bottom rails connected by vertical side struts with horizontal openings in the side struts for the reception of the ends of longitudinally extending heddle rods upon which the heddles are mounted,
