EARL C. RIPLEY, 0F SHERMAN, NEW YORK YARN CLEANER 0R sLUBBER y Application mea December ao, 1930. serial No. 505,594.

This invention relates ,toA yarn cleaners or slubbers, that is,"to devices for removing slubs, thickened portions or load places 1n the yarn While the yarn is being spooled orv 5 wound, such devices acting to prevent any 5 0r slubber illustrated, described 'and claimed in my Pat-ent No. 1,745,505'granted on February 4,1930.' 'InV this patent, I dis closed a construction embodying arplate having a, longitudinally` extending" groovev 2 through which the yarn traveled and having a closing member extending over the plate andracross the groove, the groove being-tapered both in widthand depth from the en-l tering end of the groove to the discharge end thereof and the closer being adjustable ulongitudinally ofthe groove to thus provide for a delicate adjustment of the yarn fcleanerto all diameters of yarn within the range of the device,'this adjustmenty being capable "of 'being madev either while theyarn fis still or while the yarn is running cleaner. I I

The objectof-'the present invention is to provide improved means for supportinga' through the '5 closing elementin operative engagement with' the grooved plate, thisimeans being so formed that it will have a slight eccentric contact with the face of the plate so thatra slub coming incontact with the closing element tends to pull it tighter to the plate'without, however,` decreasing the'yarn'sizing passage. This is particularly important Yin that 'in slubbers knownto me', while two parallel members close together when a slubV is caught and the yarn Vpinched olf, and in doing this, the rwholevyarnlsizing passageuis con-V this groove. The lower end of the base plate tracted and decreased in size.

Av further obj ect is to provied a closing element operating in conjunction with the plate which closes over the tapered groove in the cleaner constructed in direction of the travel of the yarn rather than movingacross or approximately at rightangles to the 'travelof the yarn and'thereby having a shearing effect. This further is important in that in practice when wild or flulfy yarns are beingrun, a fberfis frequently lcaught'and the Ayarn broken down in closing rwhere no Aslubfor other imperfection eX- ists.l In my device, the closing element tends to bunch the wild fibers' as if these wild fibers were passing into a funnel and thus the yarn is I carriedv through without breaking down theyarn. i

A furtherobject is to provide means Vwhich' 1 parts will Y v willv prevent the closing element from being placed under such strain vthatthe become broken.v Y Y Y Other objectshave to do with the details of constructionand arrangement of'parts as' will more fully appear hereinafter; n v VMy invention is illustrated in theaccompanying drawings, wherein :fl. I Figure 1 is a front elevation of a Lyarn accordance with my invention; 1 Figure 2 is a topplan view of the cleaner shown in Figure 1;

Figure 3 is a section on the line 3-3 ofFigure 1, and l l Figure 4 isA a ltopplan view of the grooved plate. f e i Referring `to these drawings, 10 designates f abase plate having atitsoppositeends'the upwardly extending lugs 1l. J ust below 'these lugs, the base Vplate carriesthe'out'- wardly extending pins orV screwsv 13 `supporting the usual- .porcelain elements over which the *yarnl passes. VMounted upon Vthe .face of the base 10 is a plate 14 which is shownvas having. an *angularflange or bracket 1'5 through which the attaching screws 16`pass.

This plate, asshown inFigures 3 and 4, is A provided withv a longitudinally. 'extending' groove 17 which tapers both in fwidth and depth from its entrance end vto its discharge end, the yarn rpassing at all times through by the devicermaybe clamped uponany decross sectional area of the groove 17.

sired portion of the spooling or winding machine.

Extending outward from the rear face of the base plate are the two ears 2O and rotatably mounted in these ears is an adj usting screw 21 having relatively line screw threads. One end of the screw has a. head 22 whereby the screw may be turned and the other end carries the nut 23.

Also disposed agai ust the rear face of the base 10 is a slide 24 which is formed to have sliding engagement with the rear face of the plate 10 and with the upper edge thereof. Through this slide, the screw threaded rod 21 passes and with it this rod has threaded engagement. The upper end of the slide carries a pin 26 extendingover the plate lll and slidably mounted upon this plate is the closing element 27. This has an angularly extending handle 28 and is formed with the upwardly extending ears 29 through which the pin 26 passes. A spring 30 engages the pin 2,6 and the portion 28 and acts to urge the closing member 27 downward toward the plate 14;. The closing member in normal position extends downward and toward the entrance end of thegroove 17 and bears against the upper face of the plate 14, which plate is preferably elevated on each side of the groove 17 as shownin Figure 3. Preferably the lower end of the closing member 27 is upwardly bent, as at 31, so that a rounded edge is provided bearing against the plate 14. The handle 28 extends slightly downward and extends over one of the lugs 11 at the entrance end of the device, this lug 11 constituting astop preventing too great downward movement of the handle 28. The spring 30 is a very light spring so that the closing member 27 is urged only lightly down against the plate.

The use of this device will be obvious from what has gone before. The yarn'is constantly moving through the groove 17 and so long as there is no slub or thickened portion on the yarn, the yarn will move freely and easily but when a slub is carried into engagement with the closing member 27, the Vslub will be broken out in an obvious' manner. There is a tendency when a slub or imperfection strikes the rounded edge of the clos ing element to pull the closing element tighter tothe plate but this is done without in any way decreasing the yarn sizing passage or The coil spring` 30 has no eect in breaking down the yarn but simply acts to provide a quick and positive closing and to hold the closing element in proper position on the shaft. The adjusting screw 21 permits of a very delicate adjustment to practically an iniinite degree of the closing element longitudinally of the groove 17 and thus provides for operating on all sizes of yarn within the range of the groove 17. It will be thus seen that. the groove 17 with the closing element provides a wholly closed aperture which is variable in cross section by adjusting the slide through the instrumentality of the screw 21. If a very heavy yarn is being sized and a slub thereon should catch the closing element, this A yarn would not spring the screw 26 and would not force the eccentric closing element past the center for the reason that the handle 28 extends over the member 11 which constitutes a stop so that this pull of a very heavy yarn which would otherwise have to be taken or supported entirely by the pin 26 will be transmitted also to the handle 28 and the lug 11 thus distributing the strain and preventing the part-s from being damaged.

Preferably, the face of the plate 14 will be provided with graduations 32 by which the position of the slide or different diameters of yarn may be adjusted.

While I have illustrated a particular form of this mechanism I do not wish to be limited thereto as it is obvious that many details might be changed without departing from the spirit of the invention as defined in the appended claims.
