LOOM.

Application filed April 29, 17927. SeralNo. 187,452.

This invention relates to a method of manufacturing pile fabric-s of the Axminster type andA to improvements in Axminster looms. latesrto the .tubing fra-mes used with such looms and a method of setting the tuft yarns on the loom spools of such tubing frames.

ln the weaving 'of Axminster rugs and carpets the yarns rer each row of tufts across the breadth of the rug' or carpety are set or wound upon one or more loom spools in accordance with a master pattern, the said spool or spools being carried with a tubing frame adapted to feed the yarns in proper arrangement to the loom.

vOne object of this invention is the provision of a tubing frame whichfwhile intended for use with a. loom designed to weaverugs or carpets of a predeterminedy width7 is equally applic-able for use with the same loom in the weaving of a rug or carpet of a narrowerl width. j

Tubing frames for Axminster type looms adapted to weme relatively wide rugsor carpets have heretofore carried. three loom spools of equal length anda false head has been provided for one end spool whereby the effective length of. that spool has been shortened so that the overall width of the rug woven therefrom is decreased by an lamount equal 'to the amount the effective length of the one spool has been shortened. f y

According tothe present invention the effective length of the end spools is unchanged but the end or Iniddle'spool is reduced in length andthe Itubing frame is made adjustable to accommodate either disposition of spools.

The invention also relates to a method of setting a plurality of spools of differing lengths as just described for .use in connection with a single tubing` vframe whereby the labor involved in the preparation of the patterns and in the step of setting the spools is materially reduced.

These and other objects of the invention More particularly the invention re-V Figure 2 shows a tubing` `frame similar to those usually provided but modiied in accordance with this invention tor receive spools set in accordance with the patterns of Figure l. l

Figure 3 is taken onthe line 3- 3 in Figure 2 looking inthe direction of the arrows and showingthe adjustment of onev of the loom spool supports on my tubing. frame.

AXminster type looms for the weaving say l of nine foot wide rugsfhave heretofore been furnished with a tubing frame such as shown in Figure Q comprising a wooden tube supporting vmember 10- to which the [metallic tubes 1l are attached. Each end of thesupporting member 10 carries a vbracket l2 formed with an ear 1.3 and catch 14 for engagement with the endless chains (not shown) which carry the seriesofftubing frames to the loom. "lhe bracket also is formed with a bearing l5 for the end Vloom spools. At-equal distances from the end` brackets l2 are usually disposed brackets, such as 18 formedwith bearings 19 wherein three loom spools of equal length, say three feet each, may be removably journalled. Then a narrower rug, say eight feet three inches iniwidth, is to be woven on the nine foot loom, the manufacturers have heretofore providedA a false head whereby the effective length of that loom spool hasy been reduced. i i y For the nine foot Axminster looms each frame carries three loom spools set with coils of tuft yarns adapted to formone row of tufts alongthe breadthof a rug.

The loom spools, are wound with spiral coils of. variouslyr colored yarn to form one row of tufts according to the master patterns along the breadth of the rug. y

The operation of transferring the yarns from the reel spools to the loom spools is called setting, Yarns from ythe reel spools, one reel spool for each-coitor tuft yarn, are led throughA a.A comb v,in the prescribed order according to the pattern and wound on the loom spool in accordance therewith. The pattern from which the spools are set represent, in substantially the samev proportions, the rug in question andy hence Figure 1 maybe considered as .a .representation of the master pattern aswell. The pattern has heretofore been sub-divided into three sections, one for each spool,V soV as to form what is7 in effect, three patte'rns,'twogv adjacentl patterns of the same width and one end pattern of a shorter width. On the other hand the design of rugs or carpets is generally symmetrical, that is, the borders of the rug at each side are similar but obviously the reverse of one another. As previously proposed the central pattern has been oil' center with respect to the central spool while a portion of what may be considered. the border and which is identical with the other side o'l' the rug has frequently had to be included on the central spool because obviously fewer tuft yarns could be set on the foreshortened end spool carrying the 'false head.

This foregoing method has necessitated the separate setting of three spools according to three separate and distinct patterns.

The present invention seeks 'to obviate the foregoing di'l'liculties and reduce the labor involved in preparing the patterns and setting the spools. As shown in liigure l, when considered as a rug, the border sections 29 and 80 at each side are similar and equal, only the reverse of one another, and hence only a single master pattern, say/W29, necessary and a single setting or the reel spools required. Then a'l'ter say the end spool. 31 is set, the other end spool 52 may be wound with the tutt yarns from the same arrangement ot reel spools by merely' rotating` the second spool 32 in a direction opposite to that in which the iirst spool was rotated to wind the tutt yarns thereon and then revers ing said loom spool 32 when it is placed in the tubing frame.

The design of the rug .is thus symmetrical with respect to the mid-section oii'the pattern 33 and as that pattern 33 is of less width than the identical. sections 29 and 30, a shorter loom spool 84C is thus necessary.v It will be readily appreciated that since the patterns for the borders are similar only one pattern need be made for both designs while the actual laying out oi the central pattern, since the design is 'centrally disposed with respect thereto, takes considerably less time.

To accommodate the shorter central spool Slon a tubing iframe of standard length, the bracket 35 is moved nearer the similar bracket 18 so as to support therebetween the loom spool 34, which is, say, 27 inches in length, and a supplemental bracket 36 is removably attached atV a distance, say of three teet, trom the displaced bracket to supporta loom spool of standard length, say three ieet, therebetween. The friction spring 3T is also moved from its position adjacent the right hand bracket l2, as seen in Figure 2. To permit adjustability the bracket 35 and, it desired, the bracket 18 may be formed with a base 39 having holes 40 tapped therein to receive screws or bolts l-l passing through suitable passages l2 drilled in the supporting member 10. Thus a pair of holes 26 may be drilled in the supporting member at a point three feet from the right hand end bracket 12, for fastening the bracket when three tootspools are used. An additional pair of holes may be drilled at a distance three feet, nineinches from the right hand end of the supporting member to receive the bracket 35 when a central spool only two teet three inches in length is used. Similarly an additional pair ot' holes 4.4 may be drilled near an end in order to permit the mounting of the supplemental bracket 3G and an additional hole 45 to permit theffastening of the friction spring 37 in the adjusted position.

lt will thus be seen that a method of setting loom spools has been provided which requires only two patterns and permits the setting of two spools from a single disposition ot reel spools and this method is rendered possible by a provision of a tubing frame which is readily adjustable to receive three spools, the central one of which is shorter than the two end spools.

Various modifications may be made in th character el the brackets serving to support the spools ou the tubing frame as well as in their method of adjust-ment and no limitation is intended by the illustrations in the accompanying drawings or phraseology in` the foregoing description except as set forth in the appended claims.

TWhat l claim is:

il. The method of weaving relatively narrow rugs and carpets on Axminster looms comprisingsetting two end loom spools from a single pattern and a-shorter central spool from a pattern of relatively narrow width.

2. The method of weaving` relatively narrow rugs and carpets on Axininster looms comprising setting two end loom spools from a single pattern anda shorter central spool from apattern of relatively narrow width, mounting the spools on a tubing- -trame ol: standard length and weaving the rug or carpet by means of a series oli such tubing frames in the usual manner.

A tubing iframev lor Amninster type looms comprising a tubing support adapted to support three loom spools of equallength, loom spool bearings carried at the ends thereof, two intermediate spool bearings also carried thereby, means to adjust one of said intermediate bearings nearer-"the other, to support a spool of shorter length, a supplemental end bearing and means to secure said supplemental bearing to the tubing support. v y

4e A. tubing frame for Axminster type looms comprising a tubing support adapted to support three loom spools of equal length, two loom spools oit equal length, a shorter central loom spool, and means. to'support said loom spools from the tubing iframe.
