NETHERCUT, OF EVANSTON, ILIINOIS. WIXDER. Application filed September Thi-@ invention relates to means for silpporting a 37arn n-lass for rewinding The invention lias special, although not exclusive, reference to meaiis for supportin- a bobbin tliat is.to be re-w ound in an automatic ivinder. For a disclosure of one type of automatic wiiider to which the present invention ',S applicable, reference may be had to the Colman Patent No. 1,267,977 d:ited lo Miy 28, 1918. The patent just mentioned discloses means for stipportin- bobbins which rot,,tte to deliver the yarn. It has been found that if the.bobbins are supported so that the yarn may be unwound from 15 the end of the bobbin, a grea,tly increased speed of windirig is attainable. A particular object of the present invention is to provide means for supporting the bol)bin for tb6 drawing off of the y,,trn froni 20 the end of the bobbin, together with autoniati6ally-operable means for dischargino, the spent bobbin and for. placing a rpserve bol)l)iii in riinning position. In the accoinpanying drawings, Figure 1 25 is ,t fragmentary sectional view t@lien transver.,;ely of a, winder embodying the features of this invention. Fig. 2 is a front view of the bobbin-holder. Fi-. 3 is a view of the .devices on the traveling mechanism for ,i o t)peratiTi,- tbc-- bobbin-bol - d---r. Fig. 4 is a ])I,in view taken in the plane of line 4-4 of Fig. 2.

Fig. 7 is a, tragmental -view illiistratiing the thread guide. In the 4ra-wings A is an- active or runninop bobbin. B is a. reserve bobbin. C is f@ 40 clamp for the end of the tliread of the reerve bobbin. 1) is L bridge across whi ch thp- reserve thread extends, and B is a, portion of a mechanism arranged to trave.1 .tloi-l- the winder. In Fi,-,. 1, the traveliiir 4;-) iiiechanism ma-v be assximed to be movillg ,iwav frorn the obser-ver. Tile embodiinent herein shown of the invention comprises a, casin- I which is rigel 11, 1919. Serial No. 323,074. prises two vertical side walls 2 and 3 rigidly secured to,etlier. In ordet' r to reduce the resi,@tance of tlle air to the tinwinding of yarn f'rom the bobbiii A, said bobbin is enclosed within a tube or 5,5 cyl.in.drical casing 4 coiiiprising two approxim@ately semi-cyliiid@ical sections. The section I@) is ri--idly inounted in tlfe inner or i-ear portioii of the casiii- 1. The section 6 is i@icridlv secured to a rock sliaft 7 whicli ro is mot@uteci in siiitable beai,in(ys in the casinFig. 6 the Iiiilged se@-' 4 may be swuil- aside bobbin to drop'@out of allow a reserve bobbin 65 casing. The rear poris enlar-ed at one side as sliown at 8 to accommodate the section 6. A toi-sion spi-iiig 9 iaoriiially holds the section-6 in closed position. 70 Wlicn yai-n is bein(y drawn off from the ciid of a bobbin in unwinding, the resistance of the air to the ballooiiin(v strand of yar'n is considerable. By enclosing the bobbin ill a casirig the air in the c,,tsing is 'caused to 75 circulate in the direction of i,otary movement of the ballooning strand of yti-n so that the resistance to said stran(I is i-naterially reduced. This resiilts in t lower an(I rnote uniform teiisioii upon the yarn bein(y 80 unwound and conseqiieiitly a Iiigher sl)eed of unwiiiding can be @ittaiiie(l- witli less danger of breakage of, the yai,n. Any suitable n-ieans iiiay be provided to -Uide the running thread as it leaves the 85 casin- 4. Herein the casing section 5 is provided with an upper end wall 10. Iii said eiid wall is a thread giiide opening 11 located axially of the casin,- 4, said opening bein- pai,tially defined by a fin,)-er 12. go The opening 11 cominunicates with a flaring throatway 13. On the end wall 10 is secured a plate 14 (Fig. 4) havin.- a fin,-er 15 which ove@laps and extends oppositely to the finger 12. The fingers 12 and 15 are 95 spaced apart as sliown in Fi--' 5 to permit the thread to pass laterally betiveen said fin(yers and enter the opening 11. After the 2n 1. As indicated in tion 6 of the casino, to -permit the sper;tthe casing 4 and to to be placed in said tion of the casing I idlv secured to the framework of the winder thread has entered said openin- it is i-e50 in a stiitable manner. The casing 1 com- tained therein by the fingers 12 and 15.- The 100

1,727,534 se I-etion 6 o@ the casing 4 has an up@er end wall 16 which, when in operatii,e position also serves to retain the running thread iii the opening 11. 5 The butt of the active bobbin is centeredbetween two concave jaws 17 and 18 fixed to the sections 5 and 6, respectively, of the casing 4. The active bobbin - is niounted upoia a skewer 19 adapted to enter the lo-,ver io portion of the bore of the @bobbin. Said sk-ewer is fixed to an arm 20 rigidly secured to a spindle 21 Nvliieh is mounted in beai-ings 22 on the casing 1. Attached to the ;lower portion of the, spindle 21 is a stud 15 23 which lies @within a caii-i slot 24 formed in a plate 25 fixe.d to the casing 1. A coiled spring 26 (Fig. 5) normally holds the spindle 21 in' the position sbown in said view. An-@arm 27 is pivoted to the casing 20 1 at 28 and has its rear end portion overlyin- the upper end 6f the spindle 21. Yigid witli the aim 27 is an ariii 29 whicli is arranued to be engaged by a cam baiF forming @art of t-he traveling 'nieclianism E. .2@ The cam slot 24 is of such form that whe;i the cam bar F acts upofi the arni 29 the spindle 21 is fii-st moved downward to Nvithdranv the skewer 19 from the bobbin A and the casin I g 4, and is then turned to swin.-I the 30 arm 20 and skewer 19 aside so as to be out of the -%vay of the bobbin A wlien the latter is allowed to fall from the casing 4. The reserve bobbin B lies witliin a pocket 30 which is mounted upon a pivot 31. The 35 pocket 30 is provided with -a bottom or support 32 and a concave seat or jaw 32a for the butt of t-lie reserve bobbin. Salid bobbin pocket 30 is notched or cut away, as shown at 33 in Figs. 4 and 6, to provide 40 clearance for the skewer 19. The pocket 30 has an upper end wall 34 ser-vin(@r as an abutment against whicii the bobbin- is pushed diiriiig the skewering of the bobbin. Vi7hen the poelret 30 is swtiii45 to transfer the reserve bobbin to tlie, casin'4 the edge of the end wall 34 carries the reserve thread into the flaring throatway 13, the winding tension serving to coinplet,e the movement of the thread into the guide 50 opening 11. . Normally the reserve bobbin pocket. 30 stands in the position shown in Fig. 5 with the upper purtion of the pocket resting against the cross-piece 35 of the casin(r 1, the 55, pocket beinc, sufficiently inclined to t, retainthe bobbili placed therein by the operator. The means herein shown for swingin the pocket 30 to carry the bobbin to the riiiinin(y posit-ion comprises a cam bar G iiiounted on 60 the traveliiig mechanism E, said cam bar being arranged to act upon a craiak arm 36 wh h is pivoted upon the axis 28 and is ic rlg id with a crank'arm 37. The arin 36' is connected- by means of a link 38 witli a 65 crank arm 39 hxed to the bobbin pocket 30. 40 's -,i contrictile sprin- acting oii the ari-n 37 to return the reserve bobbin pocket to Dorinal position after the pas,,-,,i(-e of the caiii bar G.

Wlien the operator drops a bobbin into the I)ocliet 30, the flan(ye 42 prevents the bobbin from enterin said space. If the butt of the bobbin 80 9 slioiild i-est ii[I)on said flan-e, the section 6 will push. the bobbin onto the bottom 32 when the sectioii 6 is swuing ppen. Assumino, the part8 to be in the position n F 5 the operation is as follows:, 85 g. tic traveling meelianism E s"O " B the tjme I re@ Iches the bobbin holder, the bobbin A will have beon completely unwound or the thread will have I)roke'n, @ut if the tliread is still running, the meelianism E will break the'Do thread. lii the travel of the niechanism E the cam bar F engages the arm29 and causes the skewer 19 to be withdrawn from the bobbin A and swting aside-." If the slcewer slioiild tend to stick in the bobbin, the latter 95 is lield by the jdws 17, and IS during the withdrawal of the skeiver. 'The dwell portion F' o@ the cam bar F holds the skewer in the withdrawn position@ for the necessary length of time. The cain bar or flalicre H 100 then engages the crank arm 41 and causes the'section 6 of the casino, 4 to be swung into the position shown i@ Fig. 6, whereupon the spent bobbin drops out of the casin(r.4, the bobbin being received upon a con- 105 ve-yor I (Fi-. 1) or otherwise disposed of.
