The machine shown in Fig. 1 is of the cap adapted for as worsted and. any the us- ..s may be emspinning I'lnfi'y yarn. such the like, although, of course ual forms of spinning dev' ployed.

Mounted upon the roclt shaft 19 supportby the cross-supporting bar 21 is'a rail supporting arm 22. Of course the number of pivotelly mounted supporting'arms22-inay be varied in accordance with the size of the machine, and on the ends of the'arins 22 there is rigidly secured a supporting'bar 23 provided at intervals with clips 24 to receivebetween them and the bar 23, the liexiblemetal strip 25 carrying a series of bobbin supports 26, the construction being such that the flexible strip 25 with the bobbin supports 26 secured supported upon the rail or bar 23 to. receive full bobbins onwhi h the yarn has been spun and wound.

When the full bobbins have been dolled or removed from the spinning spindles, they are transferred from to the spindle supports 26 carried by the strips 25'and a trailing end of the yarn on one of the full bobbins is connected to the leading end from an adjacent bobbin, as indicated in Fig. l. In order that the trailingend of the yarn on each bobbin, as the {yarn is spun; and wound thereon, may be available for connection with the leading end of the yarn on the adjacent bobbin when the fullbobbins are transferred from the spinning position to the spindle supports 6 of the flexible strip, the present invention contemplates that when the empty bobbins placed upon the spinning spindles 27 in the spinning machine, the end of the yarn as at a shall be given a turn about the base portion of the bobbin and be turned outthe and the bobbins have been filled connected together.

such spinning p'indles messes spinning is started, the end a of the yarn of each bobbin still prqe'cting outwardly from bobbin, the spinning operation has been completed yarn, as indicated in Fig. 1, the full bobbins are removed from the spinning spindles 27 and placed uponthe spindles 26 of the flex ible strip 25, and the trailing end a of the yarn on one bobbin is connected or tied to the leading end 5 of an adjiicent bobbin, as indicated in Fig. 4. This connection between the ends of the yarn'is conveniently made by tying the two ends together, as indicated at c,'Fig. 4:

When the bobbins have been filled by the spinning machine, as indicated inFig. 1, and nave been placed upon the s indies 26 secured to the flexible strip 25, t e'flexible strip and spindles may be removed" bodily from the spinning machine by disengage ment from the clips 24, and thereupon the trailing ends of the yarn on the adjacent bobbins may be tied to the adjacent ends of the yarn upon other bobbins and the entire flexible strip 25 with its load or series of bobbins may then be taken bodily-from spinning position and transferred as a whole to Winding position.

As indicated willthen support a series of filled bobbins d in alinement with the trailing and leading ends of the yarn of the adjacent bobbins Since it is the purpose of the present invention that the yarn from the entire series of filled bobbins shall be wound in a continuous length uponja receiver and be drawn from the ends of the bobbins, it is desirable that the strip 25 on which the bobbin supports 26 are secured may be sufliciently flexible to permit bending of the stri to direct the ends of the bobbins and the spindles on which they are supported towards winding position or preferably towards aguide from which the yarn may be delivered to winding position.

This circuniistance is indicated in Fig. 6,

wherein is shown a winding machine for winding 2. continuous length of yarn on to a receiver. In the machine of Fig. 6, the receiver or spool 28 is supported in bearings 29 extending ulm'ardly from the frame 30 of the machine, and its cylindrical surface bears upon a driven roll 31 which may be rotated from any suitable source of power.

The winding machine is provided with a support 32' which is herein shown as a trouglulilte structure. so curved that when one. of the flexible strips 25 is laid upon the support 25, the spindles and bobbins thereon as indicated at a, Fig. 1. Whenwith spun in Fig. 4, the flexible strip 25 I of the bobbins connected together, as here-- ceivei' 28,

will have their ends directed towards windmg position, so that the yarn may be withdrawn from the ends of the series of spools 1n succession and wound upon the receiver.

5 The support 32 "is preferably provided with a. strip 33 against which the end 34 of the flexible strip 25 may abut, or under which it may project when the flexible strip with its load of bobbins having the yarn inbefore described, is placed 'uponthe support 32. .If it be desired to notonly wind "the yarn from a series of bobbins on each metal strip continuously on to a single rethe trailing end of the yarn on one strip at'the terminal thereof may be connected to the leading end of the yarn on an adjacent strip when the strips are laid that any desired length of yarn in continuous lengths may be wound upon a single receiver, and in case; the receiver is a Warp beam, it will be apparent at once that the "entire length of warp may be directly delivthe flexible strips in curved position for winding the yarn, as in Fig.

Above the series of inclined spindles and bobbins held upon the support 32 is a guiderail 38 over which the yarn passes to a. guide 39, and from this guide it is led to an upper guide-roll lo supported. by an overhead support 41 from which project arms 42. From the overhead guide the yarn is then delivered in a downward direction through a traverse 4-3 for laying the yarn on a single receiver 28, as shown in. the present instance of the invention. 1 The flexible strip 25 carrying spindles 26 i is preferably formed of thin sheet metal. with the requisite flexibility for supporting the strip and its spindles in a straight position and detachable in the spinning ma chine, as indicated in Fig. 1, and thereafter to readily flex in the direction of its length,

5 as indicated in Fig. 6, so that all of the bob bins supported by tho bobbin supports 26 may have their delivery ends directed towards the overhead guide or towards Winding position.

The bobbin supports 26 may be secured to the flexible strip 25 in various ways, but a cheap and convenient way of 'lormiug such connection is to provide each of the bobbin. supports 26 with ahead or l'lalurc 44-. spotwelding the flange 44 as at -15 to the flexible metal strip 25. By spotwclding the flange upon the curved support 32, with the result,

or head 44 to the flexible strip 25 at separated points,

Fig. 5, the various stresses to. which the preferably four, as indicated in bobbin supports 26 are-subjected will'be met and counteracted by the spot-welding points 45, as indicated in Fig. 5.

' 'By the process or methodand apparatus hereinbefore described, a continuous length of yarn, determined by the number of filled bobbins carried by the'flexible strips, may be wound directly upon areceivcr from, the spinning bobbins, and theyarn itself retains its elasticity, which is sometimes impaired or destroyed in spooling the yarn at high speed and in starting warp spools in warping. This characteristic oi the invention and its advantages ,may be manifested in warping the yarn direct from thespinning bobbins, or, if desired, the yarn from the spinning bobbins may be wound upon" smaller receivers, as indicated in the present instance, and thesc receivers themselves with the load of yarn thereon in continuous and desired length maybe employed in the warpingcreel.

While the invention has been herein described in connection with spinning and Winding yarn in continuous length, the method or process and apparatus will work equally well on two-ply or multiple-ply yarns that are twisted together on a twist frame. That is, instead of spinning the yarn and placing the spun bobbins on the carrier, the advantages of the invention may be secured by twisting s on yarn, into one. or more ply-yarn, transferring the bobbins with the twisted ply yarn 'onto' the carrier, 7

and then tying the trailing end of the twisted yarn on one bobbin to the leading end of the twisted yarn on another bobbin and winding the twisted or ply yarn from the several bobbins in a continuous length onto a receiver. The term spinning as herein used is intended to make clear that the invention may be employed in connection with yarn spun direct from the roving or sliver. but does not restrict the invention in this respect, as manifestly the invention may be advantageously employed in connection with a twister-frame,\vhero two or more of the previously spun yarns are twisted together into ply yarn and wound upon a bobbin.v
