Specification of lieters'atent.

To cLZZ `whom t may concern lle it known that l, @Anne E. Toi/vsn, a citizen ot the United States. residing at Rockford, in the countyoif Winnebago and State of Illinois, have invented certain new and useful Improvements in Bohhin-Clearers, of which the following is especification.

This invention relates to mechanism for removing the waste yarn lint or thread from a core.

`The forni of mechanism herein shown is designed to reinove Waste yarn lint and threads from a bobbin and carry obi' the reino-ved matter. The bobhins usually retain aportion of the lint and threads when they have become exhausted during the spooling process, or "when they have been used in a loonilv The usual method of removing the Waste is by hand, either by grasping the shank of the hobhin and striking its nose object, or by cutting with a knife. Either of the above enumerated methods is undesirable for many reasons. 'llhe chief reason is that the bohbinis inarred andA therebyv soon rendered unfit for use. `-l- ."usinj a ineelianisin involving the generic features herein shown i ein enabled. to place the bobbins into a hop per or magazine from which they iney be fed to a clearing mechanism and discharge to a proper receptacle and freed `from all extraneous inattcr.'

F 9 is a detail view illustratinnr 'the relation of the pusher tingers to the bobbin.-

The mechanism for selecting a1id""t'e`eding` the bobbins, as well as a clearing mechanism, may be supported upon a base l having,- standards 2. @n the base l are posts 3 and (Fig. 3) havingr bearings 5`and G,- rcspectively` in which is joiirn'aledv a drive shaft 7. The shaft 7 is provided with a pulley 8 loose thereon and a fixed pulley 9. Ad-

I)acent to the pulleys, isa belt shifter l0 operable by a crank arin ll (Fig. 2) on the bracket l2, 'aid crank arni receiving inotion from the rock shaft 13 having a connection with said crank arm 1l through the 1nediuni of the link ist to which is connected, at one end, a contraction spring,T l5, byl a pin lt', the other end of the spring being connected to the underside of the basel l. rock shaft may he rocked -in its bearings 1T and i8 on the standards 2 through the nie-v diuin .et a pedal 19 rigid with said 'rock shaft. The actuation et the rock shaft 'will cause movement to he imparted tothe belt shifter l() so as to shift the belt freni the loose pulley to the drive pulley. lYi/hen 'Dressure is relieved from the pedal 19, the kelt vill be shifted back to 'the loose pulley In account of contraction ot the spring.r 15. Any suitabie inea-ns may be employed 4in lieu of the pedal mechanism for ceusinga continuous operation of the machine. Gn the end of the sh tt 7 opposite that to which the pulleys are secured, is a pinion 20. The pinion 2O is in mesh with the gear 21 on ay shaft 22 in the bearing 23 on the post- 24. A

25 is a pinion on the sha-ft 22 and in mesh with a gear 26 loose on a shaft 27 in hearings on the posts 28 and 2i). The gear 2G-1nay be `frictionally held to theshaft 27l by turning -the hand disk 30 having a sleeve 3l. .lYhen the disk 30 is turned, it will cause the adjacent faces of the gear 26 and the disk 32 to come together to rictionally engage each other, the disk 32 loting` rigidl with the shaft .2 so as te turn therewith. The clutch fea- The ture maybe omitted if desired and the shaft 27 may be positively driven through the gearing from the shaft 7. The shaft 27 drives certain operating mechanism for feeding the threadcontainer elements, to be hereinafter referred to as bobbins, to the positioner and pusher devices. On said shaft 27 (see Figs. 2, 3, 4 and 6), are cams 33 and 34, the cam 34 actuating one of the bobbin positioners or clamps and the cam 33 controlling the cutter bar which receives its rectilinear movement from a crank arm l35i on the end of said shaft 27. i

I shall first describe how the bobbins are fed to clearing position.

By reference to Figs. l and 3 it Will be observed that the bobbins may be received in a hopper or chute 36 supported on the frame of the machine. The discharge end of said hopper vterminates adjacent the positioning mechanism villustrated as two longitiidinally moving clamps, one of which is positively actuated and the other yieldingly supported. The feed mechanism lfor the bobbin comprises a shaft 37 in suitable bearings on the base 1 and running substantially the entire length thereof. The shaft 37 may be actuated by a Geneva stop motion Which is driven (in the machine shown) from the shaft 27 through the bevel gears 38 and 39 (Fig. l), one of Which is on the shaft 27 and the other on the shaft 40 in the bearing 4l on said base l. The shaft 40 carries a crank arm 42 having an anti-friction roller 43 on the end thereof, which is adapted to intermittently enter vsuccessive slots 44 in the star Wheel 45 on The contour of the, notches corresponds to' the arc ofthe periphery of thedisk 46 so that said shaft 40 may rotate Without imparting movement to the'disk 45 unless the roller on the arm 42 engages a slot 44. Alining with the discharge end of the hopper 36 and spaced a suitable distance apart are the feed Wheels 48 and 49 carried on the shaft 37. These Wheels or disks 48 and 49 are provided with' peripheral notches 48 and 49, respectively, the notches on the disk 49 being preferably smaller than those on thedisk 48 because the disk 49 Will engage the smaller end of the bobbin while the disk 48 will engage the larger end. The notches 48a and 49aare preferably of shapes to conform to the contour of the ends of the bobbins so as to better engage them. I't is apparent that the intermittent motion given to the shaft 37 will impart a corresponding motion to the disks 48 and 49 so as to inter-.

mittently feed the bobbins B to the clamp'- y preparatory to the removal thread and lint therefrom.

a longitudinally movable clamp rod 50'(Fig.- 6) supported in bearings in the posts 5l and 52. The rod 50 is provided With a collar 53 interposed between which and the post 5l is an expansion spring 54 which tends to f move t-he rod 50 into .engagement With a bobbin brought by the disks 48 49 into aline- .ment with said rod. The rod 50 is moved out of engagement With the bobbin and `permitted to move into engagement therewith, by the cam 34 Which'acts upon an antifric'- tion roller carried by a lever 58, said lever vbeing pivoted upon a shaft55 mounted in vbearings 56. rhe lower end of. the lever 58 -is .connected With one end of the rod 50 through the medium of a link 74. Hung from the shaft 55 is a lever 57 which is provided With an anti-friction roller 59 to bear against the periphery of the cam 33 on the shaft 27. Said .lever 571is connected to av I rocking elbowr lever 6l on the post 62 (see F ig. 6) by a link 63. The lever 6l is provided With an anti-friction roller 64 which bears against the nether side of the cutter bar so as to support it when it is raised. The lever 61 is also provided With a tooth or dog 65 to move into and out of engagement with a shoulder of the notch 66in the rod 50. A contraction 'spring 67 connected 69 has a tendency to move the lever I 57 against the action of its cam 33 so that said roller 59 on the lever 57 Will, at all times, be' in position to be engaged by said cam. The end of the rod 50 is provided with a bobbin i to the lever 57 at 68 and to the post 51 at',

engaging socket comprising a flared portion 70 within which is a' spring pressed ejector 7l, the spring 72 of which is sufficient to. cause the eyector 7l to prevent the bobbins being stuck in the flared portion A70. The

rod 50 is given a rectilinear `movement through the medium of its rocking lever 58 and the cam 34 which actuates it.

The

cutter bar is driven from the shaft 27,` through the medium of the crank arm 35;, 5'

.(see F igs. 3, 4 and 6). The cutter bar 75 fr.' provided with an elongated slot 76 'i y edges of which are adapted to engage til/1; roller 77 on the post 5l, whereby saai?. bar 75 may be supported at one end. The roller 64 also assists in temporarily sup porting said bar preparatory to bringing the cutter i'nto contact with the material to be .removed from the bobbin. The crank 35 is connected to the bar 75 through a ."uk 78. The forward end of the bar 75 is pre vided with an idler pulley 79 on a stud 80.

.In bearings secured on the bracket.v 82 carsaid cutter having a. shaft 84 on Which is a pulley 85, whereby said rotatory 'cutter may be driven from a belt. The bracket- 82 is rigidly fastened to the cutter bar 75 and is practically a part of it. Guard lingers 121 are adjustably secured to the cutter har 7 5 hy means of a pivot 121* and screwsl 86 and 87, the screw 86 passing .loosely through a finger 88 on the cutter bar and having ascrew-thread engagement with an arm 81a rigid with said guard fingers. The screw 87 has a screw-thread engagement with the finger 88 and hears against the arm S1, These screws are for the purpose "of adjusting the guard lingers 121 with relation to the bobbins on which they slide.

That part of the bobbin-positioning mechanism which clamps the base or butt end of the bobbin comprises an ejector sleeve 117 (Figs. 4 and 5) on the rod 118 fixed in the recess 119111 the post 90. The rod 118 has a head or enlargement 118a which engages the hollow portion of the butt end of the bobbin B. The other part of the position` ing mechanism includes the reciprocatory rod 50 with itskcj'ector 71 and its spring 72. In the post is a spring-pressed rack bar 91, the spring 92Isurrounding the bar 91 and being held withinthc barrel v93. One end of the spring 92 presses against the bushing 94 and the other end against a collar 95 on said bar. The teeth 96 of the rack 91 engage the pinion 97 on the shaft 98 in the post 90,

the teeth of the pinion 97 being in engage` ment with the 'longitudinally movable and vertically rockablc rack 99 having anelongated slot 100 engaged by a roller 101 in post 90, one end of said rack terminating in the arm 102 to which is connected a pivoted guide rod 103 having one end passing` through an opening 104 in-a. n arm 105 carried by the post 90. Interpos/ed between the arm 105 and the larm 102 is air expansion' spring 10G, the'natural tendency of which is vto force the arm 102 upward and the opposite. end of the rack downward. The opposite end ofthe rack 99 carries a pusher comprising a pair of, pusher fingers 107 to engage the threads, yarn or other substance at the hase of the liohhins and'forcc that part of it adjacent its uppermost point toward the nose of the bobbin (see Figs. 7 and 8) and into. engagement with the rotatory knife or cutter 83. When 1n retracted position. the pusher fingers are held elcvated by theshoulde'r 10T resting upon a blot-lt IUT". The lateral projection 108` on the rack 9S) is adapted to be. engaged by the roller 89 as the cutter. bar is lifted b v the roller 64 after the forward movement of said cutter bar is completed. (See Fig -1}.

By reference to Figs. 4 apd 6 it will be observed that the post 52 carries a verti cally movable spring-pressed block 109 which rests aga-inst the upper edge of the lriphe'ry of the-pulley 79 carried by the'f" bracket on 4the cutter bar and pulley 85 on the shaft 84 en which the cutterdislt is car# ried. This band also passes over a pulley 113 on a shaft 116- (Fig. 2)'iluthe,post 90."

The pulleys 111 and 113 are on fixed axes,

while the pulleys 79 and 85 are on v'constantly changing axes, the latter-being due to the fact that the supports for thepulleys 7-1 and 85 will be constantly moving toward or awayfroni the post 90. In order to take u slack from the band 112 the shaft 116 may'iie adjusted along the elongated slot 115 in said post 90 and held in its adjustnient through 114.

Motion is imparted to the drive 'shaft either by the -operator placing his foot upon the pedal 19 s'o as to shift the belt from the loose pulley to the drive pulley orthrough any other manner of starting the machine. Motion will be imparted to the shaft 27 9 through the pinion and gears 20, 21, 25 and 26 and said shaft 27 will cause the shaft 237. to receive movement through its Geneva stop motion. The rotation of-theshaft 37 will cause the disks 48 and l0 to carry `the hobbins around to the positioning devices shown as comprising the rod {JO-and the spring-pressed, alining clamp including the the medium of the hand nut sleeve 117 on the rod 118 in therecess 119 in the post 90. The sleeve 117 is resiliently projected through-'thc medium of la spring 120 (Fig.` .5). then the rod 50 is pushed* against the smallend of` thebohhin, the larger end of'the bobbin is -pushed against. the sleeve 117, which sleeve in turn is pushed back to permit the larger end of'thc hohhinto seat itself on the polnt 118*x1 of the rod 118.

s By reference to l `igs. 1 and 6, i't will be ob- .spring 54 pushes the rod 50 against the bobbin andV the-latter onto the point.118. At the same time that the rod 50'is moging forward, to clamping position, the cutter bar is moving backward out of cutting position. The pusher lingers are held out'ofpushlng the arm y c that the lbarf() vhas moved into bobbin.-v

clainpingposition, the cam 33` vhas rotated out of contact with the-roller 59 on the leverl whereupon the spring 67 places the dog e7 857m the notch 66, thuslocking the bar 50. .'.ihe descent of the roller 64 at the same time ailows the end of the bar 75 to be lowered, and vthus brings the knife (which has previously moved back to a position to begin cutting) into cutting position, but notso that the knife will rest upon the bobbin. The cutter 83, by means of t e guard ngers 121, may be so adjusted by screws 86 and 87 (as heretofore explained as to permit the knife to almost touch t e bobbin yet not come in contact therewith so as to score it. At about the time the knife begins its cluttine' movement the yfinger 88 engages the race. bar 91, as seen in F ig. to impart a longitudinal movement thereof from left to right'. This movement will impart a rotary movementto the pinion 97 in the direction of the arrowv in Fig. '5 and impart a rearward movement to the rack bar 99 from the right to the left as seen in Fig. 5, so that any material adhering to the base of the-bobbin will be yforced by the pusher fingers 107 toward the knife so thatit may be severed. may pass between the pusherfingers 107; A liingage-A ment between thefinger 88 and the rack 91 imparts only alongitudinal movement to the rack99,tbut"the spring 106 on the rod 103 will havea'tendency to yforce the end 102 of theprack 189 .upward so vastoguideA the `pusherl fingers 107 over.v the surfacefof the As soon i as stroke,

VWhen the finger 88 begins its rearward movement, it will be raised because the whole bal.' 75 willbe raised on its pivot 7 7 roller 64, thus the roller 89 while engaging the nger 108 will raise the stripper fingers 197y and the spring 92 will project the rack 91 toward the cutter bar so as to impart motion to the pinion 97 in a direction reversed to that indicated by the arrow (Fig. 5) soas to impart a retracting movement to Vthe rack 99 and thus retract the pusher finger, so that all of the parts will be in position to time that a new bobbin is positioned or alined with the rod and the sleeve 117 As soon as the waste arn has been removed from the bobbin andy the bar 50 retracted, the sleeve 117 will push the bobbin ofl' the end of the point 118*1 of the rod 118 and the carrier'comprising the disks 48 and 49 will move the cleared bobbin along to a point where it may be released by gravity into a suitable receptacle and at the same time 1- present another, bobbin to the positioner clamps comprising the rod 50 and sleeve 117.

immediately below the cutting and clearing mechanism is a suction tube 122 in communication with a suction fan casing (notshown) so that the waste lint and other extraneous matter may be removed and conveyed to a` suitable receptacle.
