ARRANGEMENT oF'srmnLEs'roR 'on ELs."

Application filed-April 11,1927. Serial No. 132,867.

My invention relates to creels or spool stands, such as are employed for supporting a plurality of spools, or yarn packages,-,so

that yarn or thread may be evenly led from i 5 the packages for Winding on a warp beam,

or forany other purpose.

. My type ofcreel in which the yarns,or threads, are the: general direction axes of the packages,- ingfknown'in the art as an end delivery, creel, as"distinguished from that type or creel" in which yarn or thread is drawn 'ofi' tangentially .to the periphery 'of the cylindrical packages; In end delivery creels as heretofore constructed, it has been customaryltoqarrange the spindles in pairs with their longitudinal axes converging'towa-rd a common point equidistant from the ends or thespindles, from hich point the yarn -1S adapted to be drawn from .a package on either spindle or a pair. I WVith this arrangement or spindles in pairs it is possible. to connect the inner end of oneyarnpackage to the outer end of the other yarn package so that yarnmay beremoved from both spindles without interruption; in other words continuous drawing of yarn is pos-, ,sible with this arrangement a v v Byrnyinvention, I provide an improved arrangement of spindles whereby yarn may be drawn continuously from a pair of spindles as heretofore without, however, making it necessary to arrange each pair of spindles in convergent relation; With myimproved arrangement it is possible'to arrange a pair or spindles with their axes inparallel relation and at the same time .to draw yarn equally well from each of the spindles from a drawing point equidistant from the ends of thespindles. *lVith all the" spindles parallel, itis possible to provide more spindles within a given space than hasbeen heretofore possible, with "each pair of spindles having their axes in 'convergent'relation. Inasmuch as theusual creel employsa very large number of'spindles, it is possible by the employment of my'invention, to either materially reduce the .overa ll "dimensions of acreelemployingva given number of spindles, or ifgiven a certain space in which to place a'creel, it is possible, by my invention,

to provide a much greater numberof parinvention relates particularly to that:

Referring lirst to Figs; l and 2, a'portion it like ofa creel stand is illustrated thcrein which generally consists ota base member 1:-having spaced uprights 2, 2 extending-- vertical- 1y therefrom. The uprightsj2'serve to carry a series-or vertically spaced horizontal spinhorizontally spaced spindles 4,. 4, extending in parallel relation-from theflrails 1 The creel alsocompris'es' a plurality'- of vertically spaced horizontal 'bars' 5, "5, each of whichcarries' a-' row of equally spaced? thread eyes6, 6,-the distance between" adjacent thread eyes 6 being twice'the' distance between a-pair of spindles 4. Asbest'shown in Fig. 1, each thread eye 6 is disposed- half idle rails 3, 3,-each' carrying a 'pluralityo't' way between a pair of "spindles l, 4, "so that theiends of a pair of spindles dareequidistant/from the opening in the corresponding threadeye 6.;Asshown in Fig.2, each row or thread-eyes 6 is located in the same horizontal planef bya spindlerail Thecreel also provldes a number or vertically extending supports 7, Twhich are 10- catedbetween the -spindle rails 3 and'the fthread' eye bars 5, the central axes, of the support 7 being in'linewith the openings in the thread eyes 6,-'as clearly shownin Fig. 1. Each support 7 carries a series ot'light weight arms 8 pivotally mounted on pins 9, each pin 9 being located belowthe horizon- 'tal plane A'A Fig.- '2, containing a'thread eye'6 and-1a pair of=spindlesL Each arm, Bca-rriesat its end a thread guide 10 "which is-located at such a distance from the axis s a row-of spindles ecarried ment withfeither, one of thepair of spindles V 4j1ocated' on opposite sides'of the support 7 of the pivot pin 9 that the opening 11 in the thread 13 is drawnthrough the thread eye 6 thread guide may be swung'into exact alineas indicated by the ful'l'line'and dotted line position'of the arm 8 in Fig. 3. vStops 8 and 8 may be provided to limit the positions of each arm 8. v r

Having described the various elements entering into my improved arrangement, there will now. be described the operation of the same, with reference to 1. Referring to the left hand portion of F ig. 1, there is shown a pair of spindles 4 with substantlally full yarn packages 12 and 12 thereon, thev thread or yarn 13 being led from the end of the left hand package 12 through the thread guide 10-to the eye 6 which is adapted to draw. from the pair of spindles in question. 7.

The innerend of the left hand: package 12 is shown M13 as extending from thetbutt of this package 12 to the front of the right hand package 12, so that when the left. hand BaCkagelQ is exhausted the thread 13 will edrawn: continuously from the right hand package 12 without interruption. It is oh:

7 in the position shown.

I carries a full package 12".

' vious that a draft on the thread 13 willcause the yarn to be unwound endwise from the package 12, as indicated by the'dotted lines,

and that the unwinding will proeeed'prop-" erly as long as the thread guidelO remains v 'Referring now to the middle pair of spindles4 shown in Fig. 1, the thread 13 is shown as having been nearly unwound from the left,

hand spindle, while the right hand spindle 4 As the last :bit of thread unwinds from the left hand spindle 4-. the thread portion 13 extending from the j butt of the exhausted spindle 'to'thefront of thefull package 12' will be drawn outwardly i forcejon the thread guide 10 tending to swing the arm 8 in a clockwise direction aboutits pivot pin 9. As previously pointed out, the arm 8 is light in weight, and as the pull on the thread 13 acts through a rela- 'tively long lever arm, the pull is sufiicient to sw'in'g the arm 8 from the full line position v of Fig. 3 to the dotted line position. In this "new position the opening ll of the'thread guide 10 is in alinement with theaxis of the spindle with the fullpackage 12 as indicated indotted lines with regard to the intermedi-ate pair of spindles in Fig. 1. "Referring now to theright hand is shown ashaving been exhausted and the arm Sis shown as having been thrown over, as prevlously descr bed to bring its thread guide flO into axial alinement with the full righthand spindle 4. In this position the pair of spindles in Fig. 1, the lefthand spindle 4 in precisely the same manner as it was drawn from the left hand spindle before the latter was exhausted.

the operator to dofi" the exhausted spindle and place a new package thereon. I When the exhausted spindle has been re- 'plenished the operator fastens the inner end hausted, the thread 13willbe drawn from the replenished spindle andthe arm Swill throw over from the right hand position to When thishas occurred there obviously remains plenty of time for the left hand positiorn as previously de scribed. 7

From the foregoing, it is apparent that by my invention 1 have provided an improved arrangement of spindles for a creel or spool stand in which the spindles may bearranged, 'With their axes parallel and thread, drawn continuously from any pair of spindlesendw the drawing o eration l/Vith improved arrangement it is possible to placethe spin I dles quite close together,jthereby per'mitting more spindles to be mounted within a given space than has been heretofore possible when arranging the spindles in pairs with their axesconvergin'gtoward th for a given pair ofspindles. v a I s In order to make more clear the particu lar advantage of myimprovedarrangement over the arrangement of converging spindles, reference is made tomy copending application, Serial No. 182,923, "filed jointly with e drawing point e Arthur L. Remington, on April 11, 1927; The above'mentioned-copending application shows an arrangement of spindles in pairs with their axes converging toward the draw.-

ing point, and the saving in space obtained by. the-use of the presentlnventlonls apparent from a comparison of the drawings of the present application andthe drawings in my copending application. ,The above mentioned copending application. also shows an improved mounting for spindles, whereby an exhausted spindle may bewithdrawn from the rowof active spindles and reversed I forthe purpose of dotting, anditfis obvious that this particular mounting of spindles may be employed in connection with the present invention without departing from the nature and the scope thereof,

Ielaim, inf, p 1. An improved arrangement of spindles forcreels, comp-rising a pair of horizontally extending spindles supported in parallel relat1on,with yarn packages thereon, a stationary thread eyelocated between said spindles and in the same 'horizontalplane therewith, and a pi-votally mounted thread guide located between the endsof saidspindlesand said thread eye, said thread guide being adapted to move under the influence of gravity into alinement witheither of said spindles.

2. In a device of the-class described, a supporting member carrying a pair of parallel horizontal spindles each having a yarn packa e thereon, a stationary thread eye located etween said spindles, through which yarn is adapted to be drawn endwise from said spindles, and a threadguide pivotally mounted on a horizontal axis between the ends of said spindles and said thread eye,

said thread guide in one position being adapted under the influence of gravity to aline itself with one of said spindles, and in its other position to aline itself with the other of said spindles.

3. In a device of the class described, a supporting member carrying a pair of parallel 3 horizontal spindles each having a yarn package thereon, a stationary thread eye located betweensaid spindles, through which yarn is adapted to be drawn endwise' from said spindles, and a thread guide pivotally mounted on a horizontal axis between the ends of said spindles and said thread eye, said thread guide in one positionbeing adapted to aline itself with one of said spindles: until the yarn thereon i-s-exhausted, whereupon thetraction of the yarn on the thread guide serves to lift said guide to a pointwhere the force of gravity drops it into alinement'with the other of said spindles.
