(Cl. 242-131) This invention relates to creels for use in the textile art and more particularly to creels for use with winding machines, twisting and doubling frames or other textile apparatus requiring the delivery of yarn from rotatable supply-packages. One object of the present invention is to Dro vide a cree] of compact structure capable of supporting a maximum number of supply-pack ages 1n a minimum space. Another object of the invention is to provide 10 a creel of the type indicated in which the supply packages are mounted on spindles movable to ward and away from the creel frame to facilitate 16 20 donning and dofñng the supplies. Another object of the invention is to provide a creel of the type indicated for rotatably sup porting groups of packages in parallel relation ship with the axes of the packages of each group oiîset from a vertical plane to provide for free delivery of the yarns from all of the sup plies. Another object of the invention is to provide a creel of the type indicated having spaced par allel stanchions between which a group of sup ply-packages are rotatably mounted on spindles 2 carried by one of the stanchions and supported in part by an adjacent stanchion. Another object of the present invention is to provide a creel of the type indicated in which the stanchions form a sectional frame for supporting 3 O the groups of supply-packages in parallel side by-side relationship so that the number of groups of packages may be increased by adding sections to the frame. Further objects of the improvement are set 35 forth in the following speciñcation which de scribes a preferred form of construction of the invention, by way of example, as illustrated by the accompanying drawings. In the drawings: Fig. l is a side elevational View of a section of a creel embodying the novel features of the pres ent invention and showing three groups of sup ply-packages with the packages of each group 45 supported between parallel stanchions in vertical spaced relationship; Fig. 2 is an end elevational view of the creel showing the supply-packages of one group ar ranged in offset relationship with one of the sup porting spindles illustrated in dash lines as hav 50 ing been moved outwardly away from the frame; and Fig. 3 is a detailed plan view of one pair of the spaced stanchions of the frame showing one of the package-supporting sp-indles moved out 65 wardly away from the stanchions. The present improved creel comprises, in gen eral, a sectional frame consisting of a plurality of vertical stanchions adapted to be mounted in spaced parallel relationship. Each stanchion has a series of arms pivotally mounted thereon which carry laterally-extending spindles. The spindles are adapted to rotatably support a group of sup ply-packages with the projecting end of’ each spindle seated in a bearing on the next adja cent stanchion. In this manner a compact ar 10 rangement of the supplies is effected and the capacity of the creel may be increased by the addition of further stanchions. The stanchions are preferably inclined forwardly so that the packages are o?îset one in advance of another t0 15 ward the top of the creel and each spindle is adapted to be moved away from the frame by rocking its supporting arm on its pivot to permit the packages to be placed thereon or doffed there 20 from. Referring now to the drawings, the creel is shown as applied to use on a twisting frame wherein a group of strands supplied from indi vidual package units arranged one above an other are twisted into a single thread. The im 25 proved creel is constructed with a sectional frame comprised of stanchions 5 arranged in spaced parallel relationship. Each of the stan chions 5 is in the form of a bracket having rear wardly-extending webs 6 and l with feet 8 and 30 9 at their ends bolted to horizontally-extending rails Ill and I I of the machine to which the creel is applied. The webs 6 and 'I are of different lengths and so proportioned that the stanchions 5 extend forwardly toward the top at a slight ‘ angle to a vertical plane to provide for support ing the supply-spindles in oi‘r’set relationship. Each stanchion 5 has forwardly-extending ears I2 arranged in vertically spaced relationship and slots I3 intermediate the ears of each pair. The slots I3 are inclined downwardly from the front of the stanchions to form socketed bearing seats for a purpose to be later explained. The for wardly-projecting ears I2 are formed with bosses I4 in which are ñxedly held pins I5 extending at 45 right-angles to the stanchions, as most clearly shown in Figs. i and 3. Arms I6 are pivotally mounted on the projecting portions of the pins I5, being held in place by collars Il' secured to the ends of the pins. Preferably, the arms I6 have laterally-extending hubs I8 bored to receive the pivot-pins I5 and serving to space the arms from the sides of the stanchions 5. Spindles 25 carried at the free ends of the arms I6 extend horizontally across the space between 2 2,120,759 the stanchions 5 of each pair with their outer ends overlying the next laterally adjacent stan chion. The distance along each arm I6 between the axes of the pin I5 and spindle 25 is equal to ì the distance between the centers of the bosses I4 and the slots I3 so that the end of each spindle will enter one of the slots and seat in the closed end thereof. Each arm I5 is thus pivotally mounted, for movement from one side to the 10 other of a vertical plane common to the axis of its pivot-pin I5, being supported in a position inclined rearwardly from this plane by the en gagement of the outer end of its spindle 25 with the end of the slot I3. Movement of the arm 15 I6 to the forward side of the vertical plane and downwardly into the position indicated by the dash lines in Fig. 2 is limited by a stop 26 pro jecting from the hub il of the arm and adapted to engage the under side of the ear I2 projecting 20 forwardly from the stanchion 5. When the pívoted arms I6 are swung forwardly and downwardly to the position illustrated by dash lines in Fig. 2 the supply-packages P may be mounted on the spindles 25 by sliding them over 25 the free ends thereof. The supply-package may be of any suitable form such as a cop, cone, spool, cheese, cake or the like and, as herein illustrated, the supply is in the form of a rayon cake sup ported on an expansible holder 28 of 'the type 30 illustrated and described in a copending appli cation of Royal Little et al., Serial No. 73,730, filed April 10, 1936. In this form of holder coni cal end members 29 and 30, indicated in Fig. l of the present drawings, cooperate with a 35 radially-expansible core or mandrel 3I to sup port the cake or package P. The end members 29 and Sil carry interengaging screw-threaded means for adjusting the diameter of the holder 28 including a hollow stud 32 for rotatably support 40 ing the holder on the spindle 25. In the preferred form of construction of the creel as herein illus trated a spacer-sleeve 34 is provided on each of the spindles 25 to compensate for the hollow ends of the package-holders 2B, whereby to 45 properly position the holders on the spindles. In the present illustrated embodiment of the invention each stanchion 5 of the creel is adapted to support a group of four supply-packages P and a series of three of such groups are shown 50 in the drawings as arranged in parallel relation ship. The stanchions 5, however, may be con structed to mount a greater or less number of supply-packages in a group, and the capacity of the creel may be increased to include any de sired number of groups by adding other stanchions 5 arranged in laterally spaced rela tionship. The improved creel having now been described in detail its mode of operation will next be explained. To load the creel with supply-packages each 60 arm I6 is rocked forwardly o-n its pivot I5 until its stop 26 engages the under side of its respec tive ear I2 on the stanchion 5. A package such as a cake P on its holder 28 is then mounted on 65 the spindle 25 by sliding the hollow stud 32 over the free end of the spindle until the end member 29 engages the spacer-sleeve 34. 'I‘he arm I6 and package-holder 23 are then rocked rear wardly until the free end of the spindle 25 enters 70 the appropriate slot i3 in thev next adjacent stanchion 5 and is seated in the closed end there of. Due to the relative position of the closed end of the slot I3 with respect to the pivot-pin i5 and holder 28 will therefore retain the end of the spindle 25 seated in the slot I3. With each of the spindles 25 of a group mounting a package P in position between a pair of laterally spaced stanchions 5 the packages are located one above YA another in vertically spaced relationship with each package off-set forwardly of the one below, due to the forwardly inclined arrangement of the stanchions. As the yarn or other strand y is drawn on? from the packages P and led down wardly to a common point below, each strand will run clear of the other packages and the inclination of the stanchions is such that should the yarn of an upper package be nearly exhausted it will still clear the periphery of a full package 15 directly below it. With the creel constructed as herein illustrated the four strands of each group are drawn down wardly and brought together to lead through the usual pigtail guide on the twisting frame or other apparatus to which the yarn is to be supplied. It will be understood, however, that the creel of the present invention is adapted for other uses and that any desired number of stanchions 5 may be arranged in parallel relationship with 25 each stanchion adapted to mount any desired number of packages. Due to the construction and arrangement of the individually mounted stanchions 5, which form a sectional frame, the creel may be quickly assembled to any size and 30 its capacity subsequently increased by merely adding further stanchions. Such facility of in stallation and extension is in part due to the arrangement of the pivotally mounted arms I6 carried wholly by one of the stanchions and 35 rockable to engage their spindles 25 with the next adjacent stanchion to support the packages in delivering position. ' It will be observed from the foregoing that the present invention provides a creel of simple and compact structure, adapted to support a maxi mum number of packages in a minimum space and to be expanded to any capacity by adding stanchions to its sectional frame. It will further be observed that the present creel facilitates the placing and cloning of the supplies and so posi tions one with respect to the other in offset relationship that a free delivery of all of the yarnsl is insured. While the invention is` herein shown as em bodied in a preferred form of construction, it is to be understood that variations may be made in the structure and arrangement of its parts without departing from the spirit or scope of the invention.
