LOOM HARNESS J. J. KAUFMANN Filed May 24, 1949 FIG.
Aug. 26, 1952 INVENTOR. JOHN J. KAUFMANN ATTORNEY- Patented Aug. 26, 1952 acotizis FFICE LOOM HARNESS John J. Kaufmann, Elkins Park, Pa., assignor to Steel Heddle Manufacturing Company, Philadelphia, Pa., a corporation of Pennsylvania Application May 24, 1949,- Serial Nb. 94,958
4 Claims. (01. 13992) This invention relates to loom harness and it relates more particularly to the construction and arrangement of frames, and the parts carried thereby, for supporting the heddles which separate the warp ends in successive sheds for the passage of the shuttle therebetween to effect the weaving operation.
Heretofore most of the frames used in looms for supporting the heddles were made with top and bottom rails or shafts of wood connected at their ends by side struts usually made of fiat metal strips secured to the ends of the top and bottom rails or shafts.
By reason of the present availabilty of light metal alloys of aluminum and the like it has Fig. 3 is a. fragmentary perspective view of certain of the parts of the harness frames, the same being shown in separated relationship to more clearly illustrate the invention.
It should, of course, be understood that the description and drawing herein are illustrative been suggested to substitute, for the top and 7 ing the actuating cords or straps thereto, and
alsoin connection with the means for supporting the heddle rods in the frames intermediate the ends thereof.
The principal object of the present invention is to provide a novel and efficient form of heddle framein which the top and bottom rails or shafts may be made of extruded hollow metal shapes, and which frame is so constructed and arranged as to provide improved means for mounting the hooks or other attaching devices to which the cords or straps for actuating the frames may be secured, and also to provide improved means for supporting the heddle rods intermediate the ends thereof. v
A further object of the invention is to provide a loom harness frame, of the character aforesaid, in which the heddles mounted on the supporting rods may have complete freedom to move from one end to the other of the frame, so that the entering of the warp may be done by means of automatic drawing-in machines.
The nature and characteristic features of the invention will be more readily understood from the following description, taken in connection with the accompanying drawing forming part hereof, in which: 1
Figure l is a front elevation of a loom harness frame embodying the main features of the present invention;
Fig. 2 is a transverse vertical section of a portion thereof, enlarged, taken on the line 22 of Fig. 1; and
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 top and bottom rails or shafts E9 of the frame are connected at their ends by means of side struts H. The side struts II may be, and preferably are, made of wood, whereas the top and bottom rails or shafts l 0 are madeof extruded metal shapes, preferably hollow, whereby they are provided with relatively thin sidewalls l2 and inner marginal portions [4, somewhat thicker than the side walls I2.
The outer marginal portion l3 of each of the top and bottom rails I0 is provided with a T-shaped groove l5 extending from end toend of the rail It, so that there is thus provided means for mounting at any required locations in the length thereof, wherever it may be desired to mount the same, two or, more hooks It for connecting the actuating cords or straps (not shown) which are used for raising and lowering the frame in the loom in the usual and customary manner. 7
Through the provision of the T-shaped groove l5 in the outer marginal portion it of each of the top and bottom rails I0, a wide variety of attaching devices may be employed for connecting the actuating cords or straps. As shown, the same may comprise the hooks I5, which are ordinary hooks having threaded shank portions IT, and having nuts l8 and I9 threaded thereon. One of said nuts I8 is located in the groove l5 and. the other of said nuts l9 bears against the outer marginal surface of the rail. This arrangement permits the adjustment of the hooks [6 in the frame for levelling and positioning the frames in the loom.
The threaded shank portion I! of the hook may extend inwardly into the hollow interior of the rail through an aperture 20 drilled in the metal of the rail which. is provided at 2| between the T-slot and the hollow interior of the rail thereby providing for a considerable range of vertical adjustment of the hooks in the rails.
Extending inwardly from the inner marginal portion of each rail or shaft l0 toward the center of the frame is a longitudinal rib or flange 22 to which there is secured, preferably by rivets 23, at suitable locations intermediate the ends of the frame, bracket members 24. Each of said bracket tion for Letters Patent, filed April 17, 1947, Serial No. 741,972, whereby the heddle rods may bezconveniently detached at the ends from the frame for the purpose of adding or removing Jhe'ddles,
either for the replacement of brokenheddles or for increasing or decreasing the count of the warp in the cloth to be woven.
Each of the heddle supporting rods 2-! provided, at the proper locations, with members 30 shaped to pass through the enlarged portions. of the slots 25 in the bracket members, but which, when a particular heddle rod?! is slid longitudinally, serve to lock the rod against lateral movement or flexing at such location. Them'embers '30 are secured to the heddle .rodsby spacers 3|.
The heddles '32 are preferably of the type shown in Figs. 2 and 3 .of my previous Letters Patent No. 2,047,511, whereby the same may have complete freedom of .movement from end to endgof the frame, and thus permitthe frames to be used in installations in which the warp is entered by automatic drawing-in machines.
Iclaim:
l. A loom harness frame comprising hollow metallic top and bottom rails connected attheir ends by .side struts, each rofsaid rails having a longitudinal rib portion projectingiinwardly toward the center of the frame, heddle-rods having their end portions detachably secured .in the side struts, bracket members secured to said ribs at locations intermediate the ends of the frame, means for interlocking portions of the heddle rods with portions of said bracket members, and heddles mountedon the heddle rods.
'2. A loom harness frame comprising hollow metallic .top and bottom rails connected at'their ends by side struts, each of said rails having a longitudinal rib portion projecting inwardly toward the center of the .frame,xbra'cket members secured to said ribs at spaced locations intermediate the ends of the frame, heddle rods having their end portions detachably secured in the side struts, means for interlocking portions of the heddle rods with portions of said bracket members upon longitudinal movement of the heddle rods, and heddles mounted on the heddle rods.
3. A loom harness frame comprising hollow metallic top and bottom rails connected at their ends by side struts, each of said rails having a longitudinal rib portion projecting inwardly toward the center of the frame, bracket members secured to said ribsat locations intermediate the ends of 'theI-rame said bracket members having slotted portions, heddle rods having their end portions detachably secured in the side struts, devices carried by the heddle rods interlockin upon longitudinal movement of the heddle rods with the slotted portions of said bracket members, and heddles mounted on the heddle rods.
4. A -loom harness frame comprising holrow metallic top and bottom rails connected attheir 'en-ds'by-side struts, each of said rails havingn longitudinal .ri'b portion projecting inwardly toward the center of the frame, bracket members fixedly secured 'to said ribs at spaced locations intermediate the ends of the frame, said bracket members having slotted portions, .heddle rods having "their end portions detachablysecuredin the side struts, devices carried by .thc'heddle rods interlocking upon longitudinal .movementsof the heddle rods with the slotted portions of said bracket members, and heddles mounted on the heddle rods.
