v To all whom it may concern.'

Be it known that I, VICTOR H. JENNINGS, a subject of the King of Great Britain, residing at lVorcester, in the county of Worcester and State of Massachusetts, h'ave 1nvented a new and useful Attachment for Looms, of which the following is a specification. This invention relates to looms, and while m capable of gene. al use, is particularly adapted for, and useful in, looms for weaving narrow fabrics.

It has beenfound 'in practice that as the warp spreads backwardly from the heddles 1g, and is under considerable tension itv constantly has. a tendency to force the heddles not only outwardly, but forwardly,l particularly at the two edges of the fabric. is not a seriousmatter ordinarily, with wide cloth, but with narrow fabrics and especially those which are tightly woven, the tension is so great and the resultant forces act on such a relatively large proportion of the warp threads that it constitutes a serious handicap in the manufacture of the goods. The results of this difhculty are that the heddles as they move back and forth come into engagement with eachother and restrict their proper operation, at the same time, practically grinding the contacting surfaces so that the warp has a great tendenc'y to b reak. The wastage from this v'cause amounts to a very large percentage, particularly in certain classes of goods. This has been a serious loss and has greatly increased the cost of narrow fabric goods, particularly that which is tightlyl woven and has a high tension on the warp.

The principalfobject of this invention is 4c to provide a simple, inexpensive, and convenient construction which shall efliciently guard against this interference of the hed-` olles, and at'the same time reducevery materially the breakage, and consequently the t5 Waste due thereto.

Further objects and advantages of the invention will ap ear hereinafter.

Reference is to4 e had to the accompanying drawings, in whichne Figure l is a transverse-vertical Sectional view of a loom showing a preferred embodiment of this invention, and Fig. 2 is a plan of the Same. l

The invention is-shown as applied to a es loom having a frame i0 provided with har- .to the space between nesses 11 and heddles 12 for guiding. the warp 13 as is well understood. A, member or frame lll is pivoted at points l5 on a stan tionary part of the frame l0 and extends to a point beyond the forward heddle. This frame is shown as comprising two Varms @ich extend from the opposite sides of the ame 10 and in this case are turned in- Wardly atl, because the invention is shown as applied to the weaving of narrow fabrics. It will be understood, however, that when used for a fabric the full width of thelooin the inner arms 17 of these memberswill be farther apart than is shown in' Fig. 2. These arms 17 are 'shown as parallel and as 70 supporting a plurality of parallel rods 18. Each of these rods extends from @ne edge of the warp to the other and extends between two Sets of parallelv heddles, consequently, these rods are spaced apart a distance e ual the sets of hedles. This member 14 can he made stationary if desired, but it is preferred to have it'pivoted on the frame l() so that it will be freefto have a slight motion. ln Vthis case it is so always supported by the lower harnesses, and its slight motion-does not interfere with the operation of the heddles. Its weight-is so small that it does not interpose any api preciable obstacle in the way of the opera--35 tion of the various parts of the machine.

On account of having the rods located as set fort-h they keep the heddles from heing forced forward, and at the same time .the

in proper alinement transversely of the loom. An important feature of advantage, how-- ever, is .that all the heddles of each set arey kept in proper position, and no heddles can e come into Contact with the heddle of the nent e5- set. It has been found in practice that by keeping the heddles separate in this way the amount of breakage is reduced by a very large percentage, and Consequently the wast` age is also greatly reduced. This has proven 10o a very important feature in certain classes l of narrow fabrics and is applicable-to Weavlng in general.y

While I have illustrated andv described a preferred embodiment of the invention, I am v awarethat many modications can be made therein by any person sllled in the art"with out departing from the Scopeofgthe invention as expressed in the claimi"f`herefore I do not wish to beflimited to all the details llc arms-17 tend also to keep the outer heddles eo gf 'construction herein shownand described, 1 l Y I 4What I do claim is Ina loom, the combination with the frame,

5 harnesses', and heddles, of apair'of movable parallel arms pivoted on the frame and extending to a point beyond the forward heddle, and a series Oparallel'bars supported by and between said arms just be- 10 low and transverse to the warp, each bar extending between two sets of heddles for keeping them separated.
