Application led July 8,

This invention relates to cieels for holding cops, cones or packages to deliver yarn, thread and other strand material theiefrom in various processes of the textile art.

A principal object of the invention is to provide a creel adapted to support a plurality of lion-rotatable cops, cones or packages to adapt the yarn to deliver over the end thereof at a high rate of speed and with a uniform tension on all of the ends.

Another important object of the invention is to provide a creel adapted to hold a re-V seive supply of yain or thread connected to the delivering` supply and arranged in such manner that when the latter is exhausted the yarn will be taken from the reserve supply so that the warping or other operation to which the material is delivered may be continuous without arresting it to doff the empty cop-holders and to creel a new set of supplies.

Another object of the invention is to provide a Creel from which the material delivers continuously without the necessity for repeatedly threading up the tension-devices, and on which the supply-cops or cones may be more conveniently and expeditiously creeled while the warping or other operation is undei way.

Another object of the invention is to provide a creel from which the yarn can be delivei'ed down to the last end on the supplycop or package without wastage from yarn left onthe holders or without requiring rewinding of the undelivered ends.

Another object of the invention is to provide means on the creel for preventing the accumulation of lint, specks, motes, or loose bits of yarn on the strand material while the ends are delivering from the supply packin general, topi-Ovide a Creel from which the.l

yarn, thread or other strand material may be r warped or transferred at maximum speed without stoppages for doifing, re-creeling or piecing up while at the same time delivering the strands under a more constant and uniform tension to improve the quality of the finished product.

The present improvements may be embodied in a creel having a form of construction sucli as described in the following specification and villustrated by way of .example in the 1927. Serial No; 204,369.

Fig. 7 isa detailed view of one of the sepa- V.preferred form of portion of the -r rator-rods through which the strands are y guided at the front or apex end of the creel. Referring first to Figs. l` and 2 of the drawings, the preferred form `of construction of the invention as herein described and ilconstituted by vertical rods or uprights 3 and 4 supported in socketed feet 5 whichare screwed or otherwise suitably fastened to the floor. |The framework of the wings 2 is made double with the rods or uprights 3 and 4: arranged in two parallel planes spaced ay The two rows of up-n short distance apart. rights are connected by horizontal tie-rods or longitudinal stringers 6 which pass through "T-shaped bearings or brackets 7 secured to the top of the uprights 3 and'l, see Fig. 2.

The two oppositeparts of thefdouble framework or wings 2are connected at the top by cross-braces 8 having bearings nat the end of their arms embracing the tie-rods 6 and secured thereto by set-screws or other means. Lateral braces 9 of graduated 'length extend between the two wings 2 of the creel to further reinforce the structure and hold the wings in inclined relation. The wings 2 may be braced from the floor by angular struts l0 and l1 which are attached to the forward and rearward endsof the horizontal l 'forward rods 4. being` adaptedztosupport the yarn-supplies C which are preferably in the form ot cross-wound cones.. flhese'coneseot yarn may be wound by any suitable method and preferably they are supported on wooden holders 15 provided with axial bores 16 for receiving the spindles or mandrels20 which mount the eones= on` the creel; lt-

willy be noted from Figs. 31and 41that each: cone-holder or. Wooden carries 15 has a pe` ripheral groove 18 in its larger end? which: is employed 'lor a' purposeas later explained; and.v alsoa circumterentiatl groove 17.y on the interior of: its bore16-by means et which the holder is heid: on the spindlef20..

The improved means i'or supporting; the cops,.cones or pack-ages C on' the creel consists essentially' ot'i a: swinging. arm'i21i carryino` the co -s )indie 2O1and-liavinoar hubor bearing 22 which turnsloosely' onV thc uprightor rod 3i. The spindlef20 projects at substantially. right-angles tothe endoty the arm 21 and is formed with a lip'or abutment 23 adapted tof engageV the internal groove 17 in thebore oii the carrier 15th retain the r cop in placeon itsA support.

The arm 2L is held on the vertical: rod 3 by means ot collar 25 against. which the end of its hub; 22 bears. adjustable vertically on the rodi 3-to1locate the cone-holder in properA relation withl respect. to its respective tensionfdevice, the

collar being securede in place'by any suitable means such asa set-screw.y 24; 'Ehe collar; 25 also providcsimeans ton holding the arm 21 in pro-per angular relation; with respect. to the rod while adaptingit t'o be swungy backl into the posit-ion illustrated by dotted.y lines inx Fig. 3 to facilitate the placing et the-cone on` thespindle 20 orl the doiiing of.'

the empty` carrier. therefrom.' The. arrange-l ment offthese'parts iszillustrated iin detail inl Figs.4 5; and 65 from which it. willi beI observed that. the collar 25 is providedwith twolugs or fingers 26 and- 27v against which the arm 2li strikes as it swings one' wavy or` the other. aroundtherod 3.-l The collar. 25l

is alsov formed with a il-shaped. groove or depression 28 in its upper face which is adapted tofbe engaged by a taperedl lug or abutment 29 on the under side ot' the hub 22. When the armI 21. is swung;- into the position shown by tull linesin Figs. 3' and 4 it willl bring; up againstl one ot the stop-Y fingers 26 ony the collar 25 and its lug 29 will drop into the \/;-shaped depression 28 The' collar. 25 is on the upper side of the collar. This engagement` ot the lug 29 with the depression 28 provides a detent to hold the arm 21 normally in position with its cop or cone properly located with relation to its respective tension-device in the manner and for the purpose as hereinafter more fully ei:- plained. llVlien the arm 2l is' swung` back into dotling position the lug' 29 will ride upout ot tliedepression 28 and slide along` the top of the collar 25 until the arm strikes the other stop-linger 27. lt will be noted 'from' Figs.. 3 and 4 that the es ot arms 2l spaced. vertically on the roo. 3 are arranged in alternate relation, one arm projectingI tothe lett ot the rod and the next arm. to the right and so on as viewed trom the'baclz. of thecrecl wing. T o conform to this arrangement ofy the arms'2i the collars 25 areeaeh formed with grooves or recesses 28 on their upper and lower surfaces so that they maybe reversed in position as shown in Fig.. 4: when employed with the .alternate rightand lett-hand arrangement ot thel arms 211 rllhe tension-devices 30 .tor applying;y tension to the yarns or threads delireringr the cones C are mounted on the smaller torward rods-4 et' the wings 2. Any suitable form ofi tension-device may be used, but l prefer to'employ a disletension comprising opposed disks 31 mounted on pins or studs 32 projecting upwardly from brackets The brackets 33' have 34 adapted to embrace the rods 4 andset-screws may be employed.y to clainpthem in plarethereon as shown inFigs. 3 and 4. Each bracket 3.2i is provided with a guiding-hook 36 through which the strand of yarn draws trom the nose of the cone C. rlhe strand is then led between the tension-disks 31 and around the pin 32 and thence draws out ai und a second guide-hook 37 on the br.. 33. The ya-rnstrointhe whole series ot cones are led forward toward the apex cad et the Creel. and the ends leading trom each horizo l rowot tension-devices are thi ,aided tluoirenA a separator 40 projecting` horizontally 'ti im the forward uprie'ht 41. These separators 40 are alined with the rows et tension-devices 30, there being' one for each row as shown in Fig. 2, and each separator provided w-ith. a series ot porcelain thread-eyes 42. through which the yarns draw. ln this way the ends from each row oi supplies held in alinement in a single bank so as to render it easy to inspect the multiplicity of strands to detect a missingl or'brolren end; From the separators 40 the ends lead 'forward= to the warping1 or other machine in which they are to be converted7 the creol being adapted for delivering; the vorn to section-beams for beam twisting. s or weaving. orto a ball warper for i the material.

lOfl

In handling and converting yarn, thread or the like at high speed considerable trouble is experienced fromthe accumulation of lint, fluff, fly7 dust, specks and motes on the running` yarn. There is necessarily a certain amount of lint generated in all processes of handling or treating yarns and where a very large number of ends are being treated, such as in a Creel, a considerable amount adheres to the jarn, forming slubs and bunches thereon, and running through the beam causes defects in the finished product. lith the present improved Creel the tension-device acts to clear the yarn of much loose fluff, lint, specks and otherl adhering matter, and this is eventually thrown off into the air and taken up again by the yarn as it passes through the creel to the warper. Such conditions are present with practically allforms of creels, but in my present improved device means are provided for eliminating this source of trouble.

I have found that by setting up an air current around the yarn-supplies and their delivering ends I may hold the lint, fluff and fly in suspension in the atmosphere to prevent it from collecting on the yarn or thread. For this purpose I make use of fans or blowers, Vlneferably electric fans which are mounted on both wings-ofthe Creel in front and above the tension-devices. Conveniently I may employ oscillating fans 43 mounted on arms or brackets 4:4: whichV are fastened to the top of the vertical uprights or rods 4. The fans 43 are suitably connected to light sockets or outlets to supply current through plug-Cords or wiring, not herein shown, and as they oscillate in the manner indicated in Fig. 2 a current of air will be blown down across the yarns leading forwardfrom the various tension-devices at the forward side of each creel-wing. I have found that three fans on each side of thecree] are usually sufcient to produce overlapping crurents of air which will completely maintain the lint and flufl' in suspension and prevent it from being deposited on and adhering to the yarns traveling through the creol to the nf'arping machine. The method of operation of my complete device is as follows: y

The cones C or other yarn packages are applied to the Creel from the back of the wings 2, there being suliicient space therebetween to permit the operator to travel from one end to the other. The cones'are taken from the winding machines, placed on suitable racks and carried in trucks to the creel and there mounted on the spindles 20, the arms 2l being` swung back into the position illustrated by dotted lines in Fig. 3 to facilitate this operation. Each cone-carrier l5 is simply slipped on over its spindle 20 and when released will drop down in position to cause the lip 23 at the end of thek exhausted the yarn will continueto deliver i from the reserve cone to avoid the necessity of stopping the warping operation to re-l plenish the supply. cones are creeled for each end to be delivered to the warper so that the whole number of cones on the Creel is twice the number of ends being warped. It will be noted by reference to Fig. 3 of the drawings that two adjacent cones in each horizontal row point toward a. single tension-device 30, and the ends of the yarn in these two cones are tied or spliced together to provide for the continuous delivery therefrom. It has been noted that the wooden cone-holders or carriers 15 are formed with peripheral grooves at their base ends and these are used to contain a short length of yarn for splicing to the end of the reserve cones. When the winding is started theend of the yarn is wrapped or coiled a few times around the carrier 15 in the groove 18 and after the cones have been creeled this length of yarn is drawn off or unwound from the groove and tied to the end leading from the next cone in the series, or, in other words, the reserve supply. The ends from the associated cones are thus spliced together along the whole creel and the ends from the first cones are then threaded through the tensiondevices 30 in the manner `as previously explained. After all of the ends have been spliced and the leading ends led through the tension-devices they are drawn forward toward the apex end of the creel and threaded through the eyes 42 in the separators 40. As illustrated'in Fig. l, the yarns from each horizontal row ofdelivering cones will lead forward in a mat or bank and, drawing through the separator 40, are thence led to the warping or other machine located in position in advance of the apex end of the creel. The large number of ends delivering from the creel will thus be separated into distinct rows or banks arranged one above another and converging at the back of the warping machine to be wound thereby on to the section-beam. This separation of the multiple ends in banks facilitates inspection so that the operator may more readily discover a broken yarn and stop the warping operation to piece up.

lith the apparatus threaded up in the warping operation proceeds the yarn from` Stated brieiiy, twolou loi?.

l'A end trom the delivering cone to the lea 20 set in place ot'. the first-exhausted ones.

35' without material fluctuation from 40 creel;

50 the elongation tests are most exac 60 case when rotating spools the first-delivering cone is eventually` exhausted, but when thispoint is reached the endleading from the first cone to the reserve cone willV be taken up, and thereafter 'the yarnA will deliver from the reserve cone until its supply is exhausted.

As the yarn from the lirst set ot cones is exhausted the attendant simply creeis a new set of cones in its place and splices the last end ot this newly ereeled supply. vr i allot the cones will not run out at the time stilltheir exhaustion tales place within a con'iparatively short p riod, but, on the k other hand, it is not required to innnediately creel a whole set of new supplies. rfhat is to say., sutlicient time will elapse betere the exhaustion ot. the reserve cones already creeledv to allow the operator to creel anotherl lt will. thus be seen that the warping-operation may be maintained continuously for as long as desired, dependent only upon the capacity of the section-beams in the warping machine.. in other words, no time is lost tor clotting the exhausted.cone-holders and recreeling new supplies and hence the whole processmay be carried on at a `maximum speed with none of. the machinery or appliances idle during the normal period ot oping operation results in a corresponding improvement in the ultimate 'fabric in which the yarn is incorporated. the yarns elasticity is of particular importance in making tire cords or Ylfabris where uniformity of tension on the ei et yarn is also important as preventing raining or breaking the yarn, thus-permitting warping at muclrhigher speedwith consequent economies in the cost ot the final pii'oduct. 'lne high speed of the warping is due in great measure to the tact that the yarn is drawn off from the supplies without rotating them, there being no inertia to overcome is the are Ve'-npleyed. This improved feature also obvz Y. the necessity of slow starting and stopping ot the warper. ln spool creels the warp/er rist be Started slowly to overcome the inertia of the spools, and likewise it must be stopped The retention of y rllhe Leeonea gradually to prevent the spools trom overrui'ming'and delivering an excess supply ot yarn. rlhe quick stopping ot the warper is important-in order that the broken ends may not be lost or run into the beam. The usual troubles from drop plies and drawbacks en slashers is thus eliminated with a resultant saving in time and improvement in the inished product.

lt has been noted that as another Jfeature ot in'iprovement means are provided on the present creel tor obviating the trouble and defects caused by lint, tlutf, iy and foreign substances collecting on the yarns. l/Jhile the warping operation is being carried on the fans i3 operate to blow a current ot air downwardly across the yarns, and being oscillated baci: and 'tort-h these currents are caused to overlap to cover the whole space through which the ends draw. rlhrough this means lint, Huil', specks, metes and loose bits of yarn are blown olil from the running ends and maintained in suspension so that they cannot be carried Ythrough the warper to the section-beam. The result is that the yarn wound on the beam is much cleaner and clearer t'rom lint and fluff or other foreign matter.

ltA will be observed that in addition to the advantages above pointed out the present improved ereel provides a most compact and etlicient device for the purpose specilied. ylhe improved apparatus permits warping yarns at a maximum rate of speed, it having been demonstrated that ay speed ot approximately 350 yards per minute can be maintained continuously as compared with a customary warper speed of 50 to 60 yards per minute with previous methods. rlhe improved ereel also provides for high speed winding on cross-wound cones, which gives an enormous saving over the slow spooling process. It has been demonstrated that including the preparation ot the yarn from the winding to the warpingthere is a saving in labor of from one-halt to two-thirds, due principally to the tact that the warping operation may be carried on continuously. ln addition to this there is a material saving in floor space, costv ot equipment and overe head, -due to the greater capacity ot the warper and creel, and therefore the requirement for a less number of units ot' machinery.

`While l have herein illustrated and described al preferred form ot construction ot the creel and a preferred method ot putting it into use, various modifications may be made in the structure and arrangement ot' its parts and its method of application to various processes oi" the textile art.
