This invention relates to yarn cleaners for removing impurities from traveling yarns and aims to provide a simple and effective device for detachingispecks and other particles from'atraveling yarn and continuously discharging and collecting such impurities.

The invention relates particularly to; the type of yarn cleaner, invented byine, in

Which'the traveling. yarn is drawn between;

a pluralityof scraping edges andthe smooth surface opposite to these edges. The invention involves improvements in the yarncleaners of this typeshown in S. Patents: Nos. 1,5e5,s50,1-,5c5,s51, 1,565,852, allissuedonDecember 15, 1925. y The improvements'eifected by the present invention include facilitating the dischargingof the impuritiesbyincline ing thesmoothsurface and the scrapingedges away from each other below the yarn, provide;

ing a collector for theimpurities, and provide ing an improved form of scraping blade;

This andother features of the lnvention may best be understood from a detailed Idescrip I tion of the specific yarn cleaner. embodying panying drawings in which I.

,The frame 10 of the cleaner is, rectangular,

and the ends 13 and 14 ofthe frame, may

convenientlyfbeintegral with the one side 15 of .the frame. To provide for adjustment,

as hereina'fter-explained, the other side 16 of the frame isfs'lidably mounted, by means of recesses l7 in itsends, on studs 18 pro-' jecting' from the ends13,114 of the frame; The $151516 is attached to theends 13,14 by means of screws 19 which pass through outwardly projecting brackets 20 secured to-the side 16, and are threaded'in the ends 13,14. Compression springs 21; surrounding these screfwsyandreacting betweentheends of the studs 18' and thebrackets 2O hold'theside 16fir1n1y' in fixedfrelation to-the heads 22 of the screws 19. These springs also preventturning of the screws under any, vibrationto: whichthe device'may be subjected."

It is apparent that the distance between the two sides of the framemay be nicely adjusted turning the screws 19.

The side 16" of the fram'e ,is set at a sufficient distance from'theend pieces 13 and 1a of the frame, to provide recesses 23'aloflojve the inner portionsof the studs 18, through which Ya yarn A may" be drawn. longitudinally across the frame in contact with the smooth-inner surface of the side 16.

Scraping elements 3O are mountedv onthe side 15 of the frame. Since the arrangement of the-scraping elementsis dependent upon the direction in which the yarn is drawn through the cleaner, '1 shall use the word front to define the surfaces of the scraping elements which face toward the front end 13 of the cleaner, from which the yarn is intended to enter the cleaner. Each scraping element 30 consists of a single piece of sheet metal providing a supporting bar 31 and a blade 32 which includes a rearwardly inclined supporting part 33 and a forwardly bent operative part 34. One end of the sup porting bar 31 is set in a transverse slot 35 in the fixed side of the frame. It is held in this slot by means of the washer 36, which is forced down by screw 37. The supportingbar 31 extends perpendicularly'from the side 15 of the frame; the supporting part 33 of a the blade 32 extends downward from the lower edge ofthe end part of the supporting bar, and is bent rearwardly so that this part of the blade is rearwardly inclined, butris perpendicular to the sides of the'cleaner; and the operative part 34 of the blade extends outwardlyfrom the outer edge of the supporting part 33 and is bent forwardly, so that while this part of the blade is rearwardly inclined from the vertical like the a supporting part of the blade, it is oblique intersect in an acute edge 41, which is the scraping edge of the blade. For convenience in threading, the upper corner 42 of the operative portion 34 of the blade is rounded The scraping elements are arranged in the cleaner with their operative edges 39 111 a common vertical plane, parallel to the sides of the cleaner and with their notches 40 aligned and just above the upper surfaces of the studs 18.

The smooth inner surfaces of the side 16 of the frame has a flat vertical portion which is directly opposite the notches of the blades, and flat portions 26, 27 above and below the portion 25 and inclined slightly away from the plane of the edges 39. of the blades. The outward inclination of the upperportion 26 facilitates drawing the yarn down into the notches in threading the cleaner, while the outward inclination of the lower portion 27 facilitates discharging of the matter removed from the yarn as hereinafter explained.

A plurality of pins extend inwardly from the side 16 of the frame, with their upper surfaces in the same horizontal plane as the upper surfaces of the studs18, to prevent the yarn from dropping below the notches 40 and the vertical portion 25 of the surface 24 when the cleaner is threaded.

A box 50, is provided to collect the impurities removed from the yarn. The box is secured around the frame of the cleaner. The top of the box is open, except for a flange 51, which provides a cover for the cleaner. The edge of this cover 51 has inclined portion 52, which co-operates with a guide 53 on the side 16 of the frame, in directing the yarn into operative position in the-"cleaner. The front and rear ends 54, 55 of the box 50 are both inclined rearwardly, but'for different purposes as hereinafter explained. To facilitate removing'the material collected in the box, the back and bottom of the box are preferably made as a continuously curved wall 56.

The cleaner is provided with the usual auxiliary devicesa tension device 57 mounted on abracket 58 secured to the front 13 of the frame 10, and a' slub catcher 59 mounted behind the rear end 14 in the frame.

The use and operation of the cleaner described are as follows: To secure the best operation of the device, the position of the side 16 is adjusted by turning the screws 19 to make the distance bet-ween the inner ends of the notches 40 and the flat surface 25 slightly less than the diameter of the yarn to be cleaned, so that both the scraping edges and the flat surface may be in firm contact withthe yarn. e

The cleaner is threaded by passing the yarn under the tension device 57 and dropping it into the space provided between the inclined portion 52 of the cover 51 and the side 16 of the frame. Itis drawn down, being guided by the curved corners 42 of the operative portions 34 of the blades and by the inclined surface 26, until it strikes the pins 45 and is thus positioned between the notches 40 and the vertical surface 25.

In theoperation of the device, the yarn is drawn in the direction of the arrow in Fig. 4. When, asis usually the case, the yarn is drawn to the-tension device from a cone or bobbin located directly below it, the yarn tends to balloon out below the tension device, as indicated by dot and dash lines in Fig. 1. The rearward inclination of the front wall 54 of the box 50 permits such ballooning, and thus allows free travel of the yarn to the tension device and the cleaner. As the yarn travels through the cleaner, the specks or other impurities which it contains and a slight amount of fibrous matter are scraped from it by the scraping edges 41. The contact of the flat surface 25 with the yarn prevents the fibrous matter from entwining about the yarn. Consequently the particles which are, of course, moving rapidly in the same direction as the yarn when they are scraped off, are directed downwardly and rearwardly between the lower portions of the blades and the inclined surface 27 The fact that this Hil space increases in width towards its bottom permits the particles to fall freely. The forward motion of the particles is such that a considerable part of them strikes the back wall 55 of the box 50. The inclination of this wall throws such particles downward, so

that all the particles and fibrous matter tend V to collect at the bottom of the box, where they are well out of the way of the yarn. The matter which collects in the box is periodically removed by passing the hand through the open top of the box and drawing the collected matter outwardly along the curved bottom of the box.

In the cleaner which is illustrated in the drawings, the supporting bars 31 of the blades are resilient so that the blades are set into vibration by the travel of the yarn. This increases their cleaning action by giving their scraping edges 41 a brushing action'as well as a scraping action on the yarn.
