40 is possible. Owing to the conical layer form The spooler 01' Spoofing machine may be of the Weft wind, however, it, has not been Of any desired type whereby yarn is wound ibl h t f t ithd the yarn upon warp spools to be afterward unwound from the side of theweft-wound bobbin, betherefrom 11 3 the warp beam. In the cause, h th r i d wi f m th spooler here typified, the frame 1 may be of 45 small part of the cone wind near the bobbin a character to support a number of spindles it will be subjected to much greater strain 2 for a series of warp spools 3, which are roand tension than when it isdrawing from tated by suitable means to wind on said the large or base part of the cone, with the spools the yarn 4 drawn from the bobbins in result that the sudden change of tension the bobbin holders; The yarn thus being 50 causes yarn breakage and non-uniformity in drawn from the bobbins by the rotation of the wind on the warp spool. As a consethespools may pass'over guide rolls 5 and quence, when the weft-wound bobbins have through guides 6 to be properly laid uponbeen used in the spooler, the yarn has been the warp spools 3, and as a convenient form drawn from the end -of the bobbin and of means for sustaining thebobbin holders, i

55 special tension devices have been necessary brackets 7 projecting from the machine frame 1, may support asuitable rod 8 to which the holders may be clamped, as will hereinafter more fully appear. In allthese respects the spooler may be of usual character and operate in the usual manner,well understood by those skilled in the art, and further elucidation in these respects is unnecessary.

In unwinding yarn from a warp-wound bobbin, the yarn can be drawn from the side of the bobbin without danger of great variation in tension by reason of this fact, because each layer of yarn extends as a cylinder longitudinally of the bobbin and its radial distance from the bobbin axis remains the same throughout the length of thelayer. In unwinding yarn from the side of a weftwound bobbin, however, the yarn. is subjected to great variation in tension, because at one time the yarn draws from the base of the cone wind and at another time draws from the apex thereof or next to the bobbin; as a consequence, the tension and strain upon the i received within a guideloop 22, Figs. 1 and yarn is constantlyvarying; To meet this condition the present invention contemplates a bobbin holder or support wherein the bobbin is permitted freedom of motion in response to the varyingstrainsupon the yarn and the effects of sudden changes in tension are nullified or reduced to a minimum, all as will more fully appear.

A preferred form of the invention come prises a bobbin holder in which the base portion of the bobbin is loosely retained in a base block and is capable of free movement therein, while the tip or small end of the permits not only rotative movement of the bobbin about its longitudlnal axis, but a bodily movement of the bobbin tip in re sponse to yarn pull to change the direction of the bobbin axis.

In Figs. 1, 2, and 3 the bobbin holder. is shown asfcomprising. a bracket or base 9 having; jaws 10 to embrace the rod8 and be secured in proper inclined position thereon. by suitable means, such as the set screw 11. The base, 9 has extending therefrom the end bearing plate 12 on which the base 13 ofthebobbin may rest, and separated from the bearing plate is a flange 15, between which. and the bearingplate 12, is loosely retained the bearing block 14. The bearing block 14 is preferably formedof fibrous-composition, such as vulcanized fiber, leatheroid, or thelike, though. the invention is obviously not restricted thereto, and saidblock is secured, to thebase 9 by means which wil permit the bearing block to move about: within limits between. the bearing plate 12and the flange. 15.. As one form of means for thus securing the. bearing block to thebase, the bearing plate 12, is provided with perforation 116 through. which passes the screw l'Z, the construction being such that while the screw l panfromfalling down from operative: posig.

holds the bearing block in the space between the bearing plate 12 and flange 15, it yet 1 permits the b'earingblock freedom of motion opening 18 for the reception of a ring 19 to engage the base '13 of the bobbin, said ring being free to rotate in the bearing block but retained thereto by suitable means, such as the flange 20, Figs. 2 and 3. Such rotatable ring may be desirable in some cases and when used gives additional freedom of movement to the base of the bobbin, but in some cases it may be omitted, the essential in this respect being that the base portion of the .bobbin be held in the bobbin holder loosely to permit the base of-the bobbin to. move with the necessary freedom under the call-of var in oull or tension of the varn asitis being unwound,

15 he tip or small end 21 of the bobbin is I, said loop being elongated to permit the 1' tip or end of the bobbin to movefreely in the direction of yarn pull, and being preferably adjustable toward and from the base 9 ifor the accommodation of bobbins of different sizes. 0 jby Figs. 1, 3, and 5, the guide loop 22 is provided at theend of a rod 23, as shown, 5 said rod having a portion 24L screw-threaded to the base 9 and being provided with a In the form of invention shown set. nut 25, whereby it may be clamped or 1 locked in adjusted position. bobbin is embraced by a guide loop which From the construction described as one good practical form of the invention, itwill be seen thatwhen a bobbin ispl aced in the holder,,its.base portion 13 while retained in the holder is loosely held, and its tip or small end 21v rests loosely. within the guide loop 22,.

'Thus both ends of the bobbin, while securely held from dis-lodgment in the holder, are permittedliberty of movement bothi rotatable and bodily in response to the varying degrees and directionsof yarn pull ,7 the effect being, that all sudden strains or-jerks upon the yarn tending to rupture the same when the yarn is led from the side of the bobbin, asindicated in Figs. 1 and 5', are met by a yielding movement of the bobbin without at the same time dislodging the bobbin and its load from operative; position in the bobbin holder.

Mountedupon the rod 23 is a pan26 having theears 2'5 and 28, Fig. 1, through which the rod 23 passes loosely so that said pan when used may adjust itself to the varying size of'yarn load on; the bobbin. Owing to the inclination of'the: holder, the pan 26, preferably curvedv in cross-section as indicated in Fig.u2,-will rest with its lower ear 28-upon the clamp nut 25, and. to prevent the tion when the bobbin is being changed, stop lugs 29 and 30 are provided at the sides of the ear 28. These stop lugs may be variously formed, but a convenient and practical construction is shown as comprising a plate 31, Figs. 1 and 2, having the lugs 29 and 30 and clamped between the base 9 and the nut 25; or they may be formed as projecting fingers 32, cast with the base 9, as indicated in Fig. 5. In either case, however, it is evident that the pan 26 may be moved upward away from the stop lugs and then turned down into dotted line position, Fig. 1, when its use is not desired, as is the case in wind ing some kinds of yarn. If desired, the pan may be entirely removed from the holder by unscrewing the rod 23, andthe bobbin holder can then be used without the pan, in which case the end or tip of the bobbin will normally rest in the bottom of the loop 22.

In Figs. 5 and 6, the support for the base of the bobbin is shown as modified somewhat. In this case the bearing plate 33is formed with a circular recess 34 and within it may be put, if desired, a ring 35, which that already described the base of the bobbin is received within the ring, so as not to bind frictionally therein and the ring itself, by its loose connection with the bracket 9, permits the desired shifting movement of the bobbin base in response to yarn pull. In Fig. 9, the rotatable ring is shown as omitted, in which case the base of the bobbin may'rest loosely within the circular opening 37, the construction and operation of the bobbin holder being in all respects substantially the same as already described. w

Fig. 6 shows a modified form of guide loop for the end 21 of the bobbin, which comprises a separate piece 38, Figs. 6 and 8, having the arms 39, between which the tip or small end of the bobbin rests, said piece being secured to the rod 40 by a set screw 41. In Fig. 6, also, the pan is dispensed with altogether and in place thereof a yarn guide 42 may be employed, said guide comprising a rod or wire secured to the base portion of rod 40 and extending toward the tip of the bobbin. In this case the guide loop is open, Fig. 8, and the yarn may be led under the guide 42 before passing to the warp spool. In all these constructions, however, it will be noted that both the base and tip portions of the bobbin are loosely supported by their respective parts to permit the bobbin to respond to the varying conditions of yarn pull, and while the several forms of bobbin holder hereinbefore described and illustrated by the drawing serve as good, practical forms of structure for securing these results, it is to be understood that the invention is not restricted thereto, but that the broad invention as defined by the claims may be embodied in other different forms.
