ATTACHMENT FOR OREELS.

Application filed March 26, 1923. Serial No. 627,755.

To all whom it may concern:

Be it known that I, ARTHUR L. REMING- TON, a citizen of the United States, residing at lVorcester, in the county of Worcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in an Attachment for Creels, of which the following, together with the accompanying drawings, is as specification.

My invention relates to creels or spool stands, such as are employed for supporting a plurality of spools so that the yarn may be convenient-1y led therefrom to a winding machine of any desired type, or directly to a loom.

The object of my invention is to provide an improved attachment for a creel or spool stand, whereby the amount of friction to which the individual warp threads or strands of yarn are subjected to, as they leave the creel, can be readily controlled in accordance with the nature of' the yarn and the manner in which it is to be handled after leaving the creel. By my invention it is possible to substantially eliminate the friction to which the yarn is subjected, or to so regulate it that each thread is subjected to the same amount of friction. The above and other advantageous features of my invention will hereinafter more fully appear, reference being had to the accompanying drawings in which Figure 1 is a View in side elevation of a portion of a creel'showing my invention applied thereto so as to eliminate friction on the yarn.

Figure 2 is an enlarged, perspective view of one of the cross bars of Fig. 1.

Figure 3 is a view in side elevation of a.

portion of a creel with my invention applied thereto so as to provide for a uniform amount of tension on the yarn.

Figure 4 is an enlarged perspective view of one of the cross bars of Fig. 3.

Figure is an enlarged detailview of o a roll support embodying my invention.

Figure 6 is a sectional view along the line 66 of Fig. 5.

Like reference characters refer to like parts in the different figures.

Referring to Fig. 1, a portion of a creel is shown, which consists of a number of spindles 1 arranged in rows, each of which carriesa spool or package 2 of yarn. An

upright 3 is provided at the front of the creel, upon which is mounted a plurality of cross bars 4, each extending across the front of the creel, the number of cross'bars 4 corresponding to the number of rows of spools or packages 2. As best shown in vFig. 2, each cross bar 4 is provided with-a plurality of eyes 5 corresponding in number to the number of spools or packages 2Ain a given row, and each eye 5 is'provided with a central opening 6 for the passage of the yarn therethrough.

With creels as previously constructed, it has been customary to lead the separate strands of yarn directly from the eyes 5 to a suitable winding machine, or loom, which provides a roll 7 on a support 8 over the surface of which all of the strands pass. As the roll 7 is located between the lowermost and uppermost cross bars 4, it is apparent that the several layers of threads will make difi'erent angles with the horizontal as they converge upon the roll 7. Consequently the layer of threads passing through the eyes 5 in one cross bar 4 will be subjected to a certain amount of friction as each bends over the lip 6 of the opening 6, and it'is apparent that the amount'of friction will Vary with the different angles which the Various layers of threads make with the horizontal. hen handling very fine yarn possessing but little tensile strength, it has been found that the variations in the amount of friction to which the different layers of threads are subjected, give rise to very undesirable results when the yarn is Wound, for the reason that difierent layers of yarn have been stretched unequally. Y It is the object of the present invention to provide an attachment for creels, whereby the above described unequal stretching is avoided by the substantial elimination of friction at the point where tllQtllIQitClS leave the creel.

rolls 9, each extending across the creel in front of a cross bar 4. As best shown in Fig. 2, each roll'9 is so supported with respect to across bar 4 that a thread passing through the opening 6 of any one of the eyes 5 will engage the periphery of the roll 9 without touching the sides of the opening 6. In other words, each roll 9' is so support- To this end I have provided a plurality of l ed with respect to the corresponding-cross bar 4. thatthe' 'threads passing through the eyes 5 of a crossbar are'all tangent to the surface of a roll 9, from which the'threads pass to the roll 7 of the Windinganachine' respective axes of rotation below the-"c one" sponding series of eyes 5, while the rolls 9 below the top of the roll? are mounted with their respective axes of vrotation above the corresponding-eyes- 5, the above statementho ldingftrue' regardless of 5 the locationof the 011-7 with respect-tothe cross bars 4.

With the improved arrangement shownin Fig'rl," it is apparent that each individual threa'c'l passes throughthe opening-'6 i of 1 its eye fi withouttouching=theeye, so that frieti o'nal engagement between the threads and the eyes *is *eliminated; As the threads pass over'or under the seve'ral rollers 9 at difi'erent'angles from the horizontal, whatever frictional engagement there may be between the' yar'n" and the roll's*9 is substantiallythe same for each individual; thread; because "of the factthatthe rolls 9 are free to turn on their respective "aic'es. From the foregoing then 'it follo ws that very fine yarn may be taken I frein the creel with the arrangement showman Fig. 1, Without subjecting the individual threads to difi"erent' degress of tension. 7

' When hand'lingcertain kinds of heavy yarn or cold, it is sometimesdesir-able that *the threads be subjectedto' a certain'ainount of tension" as they pass from the creel, a specific instance being "in" the" manufacture of fabrieifor cord tires." In the" production of cord-fabric it has been proposed to-we'ave the relativelystron'g'andfh'eavy cords which com'prises" the warp, directly from the spoolsor packages of a" creel, so that the necessity for beaniin'g the warp is eliminated; When" warpthreads are taken directly' from a creel to a lo'on'r it is desirable thatthe threads be'su bj'ected to a certain amou t of tension, although in i this case it is" very essential that the tension in" each thread be? the same; Thepresent invention also contemplates a modification erthearrangement shown- F ig: 1, whereby the threads taken from the creel=- are 'eac1r subjected" to an equal amount of 'tension, which may" be regulatedlteferring nowto Fig. 3, there is shown a portion of a' creel comprlsing the usual 'spindlesliO,'spools or packages' 11', and cross bars 12 ealieh having a row of eye's13i As best'shown in Fig. 4,41 roll 14 is'rotatably supported in front-of, and below each'cross bar 12', so that a thread passingthrough the opening-150i an eye 13 to the-roll 14- will bedrawn'over the lip1'5 at a-definite. angle,

' which" is" the same for-eachofthe rolls 14.

' After passing-under the rolls- 14* the threads passftoa rolll6 on a stand 17 which'may be placed in front of a'loom, to "which the threads pass directly for forming the warp of a fabric; It is apparent from an-inspectionof- Fig: 8, that- -each thread will be subjected to a certainnmou-nt of friction as it is drawn downwardly over the lip 15 and thatithis friction will be the same for each individual thread. Consequently all of the threads-will pass to' the loom with a certain amount of tension which will be uniform. The fact that the several-layersof threads converge upon the roll '16' at' ditferen'tangles to the horizontal, does not :m'ateria-lly affect the degree of tension in' the threads because of the fact that each of the rollslt isfree to rotate on its 'axis,"ther'eby substantially eliminatingfriction between the threadsand the rolls 14.-

Referring now'to Figs, -5 and 6,";ther'e is shown a cross bar 18 having a fixture 19 attached theretd for rotatably"supporting one end of aroll 20' insuch a -mann'er that it may be employed in connection withxeither of the arrangements shown in" Figs. lrand '3. The fixture 19 provides an annular portion 21 within which is received a 'di'sk122 tu'rnable therein, and" ad'apted' to" be' 'se'curedin any desired angular position-by aset screw 23. A pin 24 is carried? by the disltf221eece'n trio to the axis of'the" annular portion 921,-

and theroll 20 is rotatably' supported at one end by'the pin- 24 A fixture'ssimilar'to the-fixture 19 is provided at theioth'er end of the crossibar 18 forsuppnrtingthe other end of the roll 20. I1r=the full: line position,- the roll 20 is sov supportedthat a-rthread passing" through the opening; 25 0f an eye 26-is tangent to its periphery. Byturning the" disk 22, the roll 20; maybe brought into the dotted linepositionsothat a thread pass- 1 ing through the openingz25' is drawn downwardly over the lip 2 5 inwpassing to the roll 20.

my invention I 'haVe provided an improved attachment for use in connection witlrcree'ls or spool stands, whereby the: amount. offriction to which the threads aresubjected in passingthrough. the cross bars of the" creel is: always maintained substantially iinidferm 1 and may be varied from'substantially: zero to a definite amount, asmaybe desired.-
