LOOM-HARNESS.

l Application led September 15, 1917. Serial No. 191,513.

c To all whom tmay concern:

Be it lniown that I, JACoB KA'UFMANN, a citizen of .the .United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in 'l Loom-Harness, of which the following isa specification.

My invention relates to loom harness and 1t has more particular relation to improved 'means for mounting groups of heddles in the loom harness for spaced andy edge work. It is well known to those skilled in the art of weaving that the heddles which control the Warp ends of the selvage, particularly in ribbon weaving, are worn out much faster than the main heddles, and furthermore in various kinds of weaving lit is frequently desirable to change small groups of heddles to vobtain slight variations in the pattern without necessitating the rearrangement of the entire body of heddles in the several frames. The object of my invention therefore is to provide a simple and eicient heddle holder adapted to support av small group of heddles, which heddle holder is so constructed and arranged as to permit the heddle holder itself to be easily changed as to its position in the harness and which also permits small groups of heddles to be rearranged with a minimum of trouble at desired location as well as also to permit easy replacement of worn or broken heddles.l v Y The nature and characteristic features of my invention will be more readily understood from the following description taken in connection with the accompanying drawin s forming part hereof, in which;

igure 1 is a perspective view of a heddle holder embodying the main features of my invention, the same bein shown supporting a roup of heddles whic .in turn are indivi ually maintained in a normal vertical position vby means of lingos attached to their lower ends;

Fig. 2 is a similar view showing, however, the arrangement of a pair of the heddle holders mounted in a harness frame having to`and bottom bars of the usual type; p ig. 3 is a perspective view of theheddle holder detached; and A Fig. 4 is a fragmentary showing the manner of mounting the heddles in the holder. f

Referring now more particularly to Fig. 1

side elevation of the drawings, 5 is a harness bar upon which the holder 6 of my present invention is mounted. This heddle holder, which is shownin enlarged perspective in Fig. 3, comprises a thin fiat strip of metal, the body portion 7 of which is adapted to surround the harness frame bar and is of complemental shape. Depending from each side of the main body portion 7 is a tongue 8, which is slotted as at 9, the slot of one of the tongues extending open to the one edge of said tongue, andthe slot of the other tongue extending to the opposite edge thereof, whereby there is thus provided central opening 10 which is closed on the one side by the bridge member 11 of the one tongue and on the other side by the bridge member 11 of the swung back to the normal-vertical position engaging yboth projections 12 (see Fig. 4) thus serving to lock the holder in the c sed position so lon as the heddles remain in the normal vertical position shown in Fig. 1, and to prevent any accidental disarrangement each of the heddles 13 may be provided at its lower end with a lingo 14: of the usual yIt will be noted that the upper ed es of the projections 12 are in alinement wit each other, and that the opening 10 is of sulicient width whereby there will be afforded a bearin surface sufficiently loner to accommodate t e requisite' number of heddles required in each group, as well also as to permit the mountng ofthe heddles in the holder as above set forth (see Fi 4). It should also be noted that the holder is preferably made of spring steel or similar material so as not only to permit the placing of -the device upon the harness frame bar at the de sired location but also to provide a slight the saine are mounted in the holder.

Inv Fig. 2 there is shown a pair ofthe heddle holders, mounted on the top and bottom bars respectively of a heddle frame of tension upon the sides of the heddles when f theusual rectangular form, and in this tinst'ance'the eyes of the heddles 13 are suiiiciently long to permit sufficient play whereby after the heddles at one end are mounted in the holder at that end, the heddles may be flexed or temporarily bent at the other end to be swung into engagement with `the holder at that end. t will of course be understood *that while\ this method of mounting the heddles in the frame may not be practical in some instances on account of the particular dimensions of the parts, the arrangement shown in Fig. 2 may however in those cases be employed at the ends of the frame by temporarily removing lthe end bars of the heddle frame and sliding the holders on the top and bottom bars, the group of heddles having and arranged as to permit the heddles to be uickly and easily mounted and dismounted A ori the purpose of renewal when the same are worn.

Having thus described the nature and characteristic features of my invention, what 'I claim as new and desire to secure by Let-l ters Patent is; f

In a' loom harness, a heddle holder comprising a strip of metal adaptedto surround the harness frame bar and having depending tongues, each of said tongues having slots extending respectivelyto opposite sides oftsaid tongues to thereby provide a central opening having suiiicient lateral `extension to accommodate ra group kof heddles and providing a horizontal bearing surface for the eyes of said heddles, and saidholder being made of thin flat s ring metal.
