To all whom it may concern. I

Be it known that I, Gnonon WV. Fosrnn, a citizen of the United States, residing at Providence, in the county of Providence, State of Rhode Island, have invented certain new and useful Improvements in Bobbin-Magazines, of which the following is aspecification.

My invention is an improved creel or sup ply-magazine for use in deliveringyarn, threador the like to winding machines and other textile apparatus. The object of my improvement is to provide means for sup porting a plurality of cops or bobbins in series with their ends tied or spliced together and held under tension so that the yard will unwind continuously from one bobbin to another without interruption in its delivery until the whole supply is exhausted. To this end my invention consists essentially, of a device for mounting the bobbins in series with their delivery-ends arranged in alinement with guiding-means over which the last-delivering end of the yarn from one bobbin draws to the leading end of the nextbobbin, to which it is spliced, and with means for holding the spliced ends under tension to prevent them from becoming en-' provide for an unrestricted,

tangled and to, uninterrupted delivery from one bobbin to another throughout the whole series In .this way my improved magazine furnishes a continuoussupply of yarn from a series of bobbins for delivery to a winding or other machine without requiring stopping the operation of the machine to piece up the ends. My improved device provides for important economies in the operation of the machine to which it is applied, thus increasing its production while also improving the .character of its product as more fully set forth hereinafter.

The manner and means for carrying out these improvements are fully described in the following specification, illustrated by.the accompanying drawings, in which like reference characters designate like parts. In the drawings Figure 1 is an elevation of a usual style of winding machine showing my improved bobbin-magazine applied to use in connection therewith;

nor of connecting their ends and threading them up;

Fig. 3, a side view of the same;

Fig. 4, an end View; and Fig. 5, a view in detail of the tension-device or end-holding-means for the spliced yarns.

Referring first to Fig. 2, my improved bobbin-magazine or creel may be made of any appropriate shape, but as here shown takes the form of a rectangular frame F preferably constructed of wood, sheet-metal For the sake of convenience in describing it, the end f of the frame F may be considered its base, f its top and f-fand f its sides, although in practice the magazine may be set in other positions than that here shown, for instance, with the side 7 serving as its base. Along the inside of the upright f is a series of bobbin-holders H, H, etc., for supporting t-he cops or bobbins B in parallel alinement. The holdersH may be of any preferred form as usually employed for similar purposes, but as here shown consist simply of wooden plugs having pins h fastened in holes in the side f and formed with conical portions h adapted to fit tightly within the tapered bores of the wooden bobbins b on which the yarn is wound. In some instances where a different form of supply-bobbin is to be used, such as a cop Wound on a paper tube, the holder H might take the form of a dead spindle or, if preferred, an expansible spring-catc h, or an outer spring-clip such as used on shuttles could be employed. With the present arrangement the bobbin b is merely forced onto the tapered holder H with a wedging fit to hold it in place with I Referring to Fig. 3, the side f of the frame F is constructed with two parallel strips f, spaced slightly apart and fastened by screws, nails or other means to the ends of the base f and top f. Extending between the strips f, f are the yarn-guides g, 7, etc.,

.- arranged in series and spacedto bring them in alinement with the axes of the bobbins B when the latter are placed on their holders H. The guides g, 9, may conveniently be constructed in the form of round, metal pins having their ends inserted in transverse holes in the strips 7, i Any other suitable guide such as a porcelain rod or looped wire might be used in place of the pins 9, but thisdetail is not important.

Secured to the side of the upright f and spaced between the centers of the bobbinholtlers H are the tension-devices or endholding clips C also arrangedin series and corresponding in number to the number of bobbins used in the magazine. As illustrated in detail in Fig. 5 the clips 0 consist simply of two overlying, flat pieces 0, 0 of spring-metal, held together and fastened in place by the screws 0. The ends of the pieces 0, c are preferably spread apart or curved outwardly-at the top to provide a flaring entrancefor the yarn to facilitate.

the operation of drawing it into place to be clamped between the sides of the clip.

Referring to Fig. 4, the end of the top piece f is cut away at f and a wire pigtail P of usual form is driven into the wood to secure it in place with its eye p in alinement with the yarn-guiding pins 9, 9, etc. Fastened to the side of the upright f see Figs. 1 and 2, is a pair of clamping-fingers D, D preferably constructed of spring-metal and shaped to adapt them to be sprung around a rod or other support on the machine to which the magazine is attached. The method of applying'the device to use is as follows: 3

Referring to Fig." 2, the frame F is set in any convenient position and the full bobbins B are fitted snugly to their holders H. The leading or delivery end 3/ of the yarn on the first bobbin 1 is then drawn up over the first guiding-pin g in the series and thence led through the eye p of the pigtail P. The opposite or last-delivering end y of the yarn on this bobbin is next tied or spliced to the leading end 3 of the next bobbin 2 after this end has first been drawn up over the second guiding-pin g of the series. After these two ends of the yarn from the'adjacent bobbins 1 and 2 have been tied together as shown at m in Fig. 2 the end 3 is drawn down into the tension-clip O to hold it taut where it leads from the base of the bobbin 1, while the end 7 v leading from the nose of the bobbin 2 is left relatively slack. It will be understood that when the yarn is spun or wound on its wooden support or bobbin 1) the first-wound and last-delivering end y is left free to provide for its subsequent splicing to the leading end 3 of the next bolrun in the series. That is to say, in the proces; of spinning or winding the yarn on its support a free length of yarn y is measured off at the start and this is usually coiled loosely arounu the butt of the bobbin 7) to hold it in reserve and prevent it from being snarled or broken. When the bobbins are placed in the magazine the ends y are simply pulled off or uncoiled to provide the free length for tying up to the delivery-end of the next bobbin. In this manner the last end of the yarn from each bobbin in the series is spliced to the first or i I leading end of the next bobbin as shown in Fig. 2. The connected ends of all the bobbins are then drawn into the tension-clips C and this last provision for holding the ends taut is most important as otherwise the yarn will not deliver freely but is apt to snarl and kink resulting in broken ends which interrupt the delivery. That is to say, it has been found that unless the yarn is held relatively taut where it leads from the base of one bobbin to the nose of the next bobbin the last end will not unwind freely but isliable to I kink and snarl or to catch on the butt of the bobbin causing it to be broken.

Usually the bobbins are. applied to the magazine and their ends spliced together by one or more operators who do this work alone. This tends toward greater care and more expert attention in the tying of the knots and results in better and more uniform work. After the magazines have been supplied with the bobbins and the ends have been properly tied up and positioned as above described the frames F are taken to the machine to which the yarn is to be supplied. In applying the magazines to the machines they maybe arranged in anyconvenient manner by placing them in racks, setting them on the floor or attaching them 'to supports overhead. In Fig. 1, I have illustrated the preferred manner of their use in connection with a well known type of conewinding machine. These machines are usually arranged with a series of heads W end, y of the yarn may be drawn up and.

threaded therethrough, whence it leads to the winding-spindle S. It will be understood that there are a plurality of heads W on the bed K, each with.a separate spindle S overhanging its front. In applying the magazines to the machine it has been found convenient to set a considerable number of them in place under the several spindles S, as many-as can be accommodated in the space between the le s L. In this way the operator of the maciine is always provided with an ample supply of full bobbins so that when one magazine is run out or exhausted an other one may be slid into place. Thebobbin-tender who distributes the magazines has simply to remove the exhausted ones and replace them with full ones and in this way the machine is kept continuously supplied and the operator is relieved of the work of \then merely placing the bobbins and tying up the ends.

In other words, the machine operator has only to operate the machines and to piece up once for each winding as next explained.

\Vit'li a supply of filled magazines in place under the machine the operator sim-. ply slides the nearest one into position be low the appropriate. tension-device T so P will aline therewith.

that the pigtail The yarn y is then drawn upthrough the 'T and its end secured! to the winding-spindle S. The operator has to start the machine and the yarn will be 'tinuously from the whole series of bobbins B in the magazine F. That is to say, the yarn y will first unwind from the upper bobbin 1 and when this is exhausted its last-delivery end y will be drawn out from the tension-clipC and the slack extending between the first bobbin and the second one after whichthe bobbinwill be"'taken up,, 2 will begin to deliver. I is exhausted from bobbin 2, the slack held in the next tension-clip C is again taken up and bobbin 3 commences to deliver and so on down through the last bobbin in the series.

After the yarn It is to be noted that as the yarn deliv-' ers from each bobbin in the series it draws around the-appropriate guiding-pin g and then straight up through the pigtail P. In I this way a constant tension is maintained on the delivering yarn from the first bobbin down to the last one in the magazine. Furthermore, as the yarn lower bobbins it draws of pins gand is thereby prevented fromexcessive ballooning so that no serious, fluctuations in the resistance to its delivery can occur from this cause.- i Usually a sufficient number of bobbins is placed in the magazine F to supply enough yarn for one full cone or package Y wound on the spindle chine from start to finish of the package. After the package" is completed it is removed from the machine, another magazine F is slid into place, the yarn therefrom threaded up to the spindle S as before described and the winding started once more. The machine is'usually arranged to stop automatically when the package attains the required size so that the operator needs only to give his attention atthe commencement of the winding. It will thus be seen that the operator is relieved of all the work of supplying new bobbins each time the yarn is exhausted from the one delivering because the delivery is made continuous from start to finish of each package. In some instances when it is desired to wind packages of a specified weight or containing a certain predetermined yardage of material wound onto the spindle S con rally spirit or-scope of the invention; delivers from the up past the seriesporting a plurality .to adapt-the S, so that the windilng is made continuous without stopping the ma the yarn wound onto the supply-bobbins may be first-weighed or measured accordingly. The winding machine will stop automatically when the supply runs out and in this way all packages may be wound of uniform size or Weight withoutv attention onlthe part of the operator as to this detai It Will be seen from the above that my improved magazine provides a more convenient and economical method of supplying yarn to winding or othertextile machines.

Through its use the operator is relieved of thework of placing the individual bobbins and piecing up the ends and is therefore free to give his whole time to the manipulation of the machine itself. This naturesults in allowing the operator to tend a greater number of machines, thereby increasing the production both p'er spindle and per operator while also improving the quality of the product. Where the operator has only to look after the machine itself it is obvious that better and more expert attention can be given thereto. Furthermore, where the piecing up of the bobbins is performed by one or more operators particularly skilled in this work the knots will be tied more evenly and uniformly resulting in an improved quality of the fabric in which the yarn is ultimately used.
