'YARN CLEANER.

f Application fat-(1v october 30, 192e.

To all whom t may concern:

Be it known that I, Lotus B. HAsnnoUoK, a citizen of the United States, residing at Elmira, in the county of Chemung and State of New York, have invented certain new and useful Improvements in Yarn Cleaners, fully described and represented in the following` specification and the accompanying drawing, forming a part of the same.

This invention relates to yarn cleaners for removing impurities from traveling yarns, and aims to provide a simple and effective device for detaching specls and other impurities from a traveling yarn and continuously discharging such impurities from the cleaner.

Yarn cleaners heretofore made have been provided with transverse blades having operating edges adjacent to the yarn and designed to detach impurities from the yarn by a scraping action, or by a scraping and brushing action. It has been found that when such edges are set in close contact to the yarn so as to have the most effective scraping action, the fibrous matter which is inevitably scraped from the yarn With the impurities tends to Wind about the yarn in front of the scraping edges. This results in forming rings of fiber about the yarn which increase in size until they become reattached to the yarn, forming bunches or slubs on the yarn which detract from its usefulness. y

I have discovered that this difficulty may be altogether eliminated by placing a smooth surface opposite the edges of the transverse blades and positioning this surface so that it is in contact. with one side of the yarn while the edges of the blades contact with the other side of the yarn. The distance between the edges ofthe blades and the smooth surface may be made less than the normal diameter of the yarn so that the blades contact firmly with the yarn and have an effective scraping action; While, at the same time, the smooth surface lies in close contact with one side of the yarn and thus positively prevents any fiber which may be loosened from the yarn from passing around the yarn to form rings and bunches. As the result, the impurities With any fiber which may be attached to them are effectively discharged from the cleaner.

by the travel of the yarn across their edges.

In order that the various features and advantages of the invention may clearly be understood, I will describe in detail a speci fic yarn cleaner embodying the invention in a form which I have found effective. Such a cleaner is shown in the accompanying drawings; in which Fig. 1 is a plan view of the cleaner;

Fig. 2 is a sidey vieiv of the cleaner sectioned on the line 2 2 of Fig. 1;

Fig. 3 is an enlarged transverse section of the cleaner taken on the line 3 8 of Fig. 1;

Fig. 4 is a fragmentary horizontal section of the line 4 4 of Fig. 3; and

Fig. 5 is a perspective view of one of the blades of the cleaner.

The yarn cleaner illustrated has a rectangular frame 1() which may be provided With a bracket 11 for supporting the frame from a horizontal rod 12. The frame has a fixed side 13 and a movable or adjustable side 14. The ends 15, 16 of the frame may be made integral With the fixed side 13 of the frame. A tension device 17 is secured to the front end 15 of the frame, that is, the end at which the traveling yarn enters the cleaner. The inside of the side 13 provides a smooth flat vertical surface 2O and the ends 15 and 16 have recesses 21, 22 in their upper surfaces positioned to permit a yarn A, which has been passed through the tension device, to be drawn longitudinally across the frame and in contact with the surface 20.

Cleaning and deflecting elements 30 are mounted on the movable side 14 of the frame, extend inwardly therefrom, and are provided With operative edges 31 lying in a common vertical plane parallel to the surface 20. In order that these edges may be brought into firm contact with the yarn A Which is drawn along the surface Q0 regardless of the size of the particular yarn to be cleaned, the side 14 is mounted so that its distance from the fixed side 13 of the frame .may be nicely adjusted. The means by which this adjustment is secured constitute a part of the present invention.

The front and rear ends 15, 1G of the 'trame 10 are provided at their outer ends with vertical surfaces 40, 41 which are inclined at the same small angle to the fixed side 13 ot the frame. The movable side 14 is provided with end portions 42, 43 which have inner surfaces 44, 45 which are inclined to the side 14 at the same angle as that at which the surfaces 40, 41 are inclined to the side 13. r1`he side 14 is secured to the ends 15, 1G with its surfaces 44, 45 in contact with their surtaces 40, 41, by means ot screws 4G which pass through longitudinal slots 47 in end portions oit the side 14. By loosening the screws 4G the side 14 may be adjusted endwise in either direction. llt/*hen it is moved toward the trout end ot the cleaner it is brought slightly further from the tixed side 13, and when moved rearwardly it is brought slightly nearer to the side 13. The inclination ot' the inclined surt'aces is so slight that tightening ol' the screws 46, after the proper adjustment has been obtained, does not cause longitudinal movement of the side 14. Furthermore, because ot the tact that the inclined surfaces are all inclined at the same angle, adjustment ot the side 14 does not change the angle between the side 14 and the side 13. Inail adjustments ot the side 14, theretore, the edges 31 of the elements 30 are all at a unit'orm distance troni the surface Q0.

ln the form shown, each cleaning and dellectiug element consists ot a single piece oitl sheet metal Forming a blade Sli! and a resilient support S3. The outer end portion ot the resilient support 3S is set in a transverse slot 34 in a movable side 1lot" the trame. It is held in this slot by means o't a washer 35 which forced down by a screw lti. The resilient support 33 extends straight inward 'trom the side 14 ot' the frame, while the blade 32 extends transversely to the line et travel ot' the yarn and is inclined rearwardlyv from the vertical at an angle ot about 35. The operative edge 31 ot the blade 5l?, is straight and perpendicular to the resilient support 33. and is inclined to the line ot travel of the yarn by reason ot the inclination o't the blade. The operative edge 31 is made acute by forming a` beveled surface 3T on the rear side of the blade. To tacilitate threading, the upper corner ot the edge 3l ot the blade 32 is rounded ott' at 38.

Each of the cleaning` and det'lecting elements 30 is free to vibrate through the bending ot its resilient support rlhe bending of each resilient support occurs principally at the part o1: the support just inside the side 14 of the frame. Consequently' when the edge 31 et one of the blades 32 is struck by .a particle projecting from the ever, each ot' the blades is inclined to the vertical axis about which it turns, the lower end of its edge 31 moves outwardly from the surface 2O to a greater extent than the upper portion of its inner edge. As a result when one ot the resilient supports 3S is bent rearwardly, the operative edge 31 ot the blade instead ot lying parallel to the surte/e Q0, as in its normal position, diverges trom the surface 2O toward its lower end.

A plurality of pins extend inwardly trom the side 13 of the trame. The upper surfaces ot these pins lie in the same hori- Zontal plane as the lower ends of the recesses 21, so that the pins prevent the yarn trom dropping below the blades 4Q when the cleaner is threaded, or in case the yarn is slacliened in the course ot the operation oli the cleaner.

'ln using the device which has been described, the position ot the side 14 is nrst adjusted to' make the distance between the edges S1 and the sur't'ace Q0 slightly less than the. normal diameter ot the yarn to be cleaned. so that both the edges 31 and the surface Q0 will be in tirm contact with the yarn when it is drawn through the cleaner. rlhe edges are, however, not set close enough to the surface Q0 to pinch the yarn or to e-Lert a material drag or tension on it'.

Vlin the operation ol the device the yarn is drawn through the cleaner in the direction ot the arrow in Figs. l and by means ot' a spooling, winding, or other machine not shown in the drawings. The travel ot the yarn across the edgeso't the blades sets the blades into vibration, and the edges ot the blades detach specls and other impurities lrom the yarn by a scraping and brushing` action. Since the surface 20 is in tirm contact with the yarn, it positively prevents any fiber removed trom the yarn by the edges trom winding around the yarn and becoming reattached to it. Consequently, the dirt removed trom the yarn, together with all librous matter removed with it, is deflected downwardly by the blades and con t'inuously discharged at the bottom olf theI cleaner. The slight outward turning;` ot the blades which occurs in their vibration prevents any tiber from beconiing caught between the edges of the blades and the snrace 20.

Since, owing to the presence of the sur- Jface 20, the edges of the blades may be placed in tirm cont-act with the yarn withfit) ltlfl llO out danger' of causing loose fibers to entwine about the yarn in front of the edges, the scraping action of the edges is very effectiveL-so effective, indeed, that in some cases the brushing action of the edges is not needed, and, in consequence, the supports of the blades may be made rigid instead of resilient. Thus, While the vibration of the blades possesses advantages, I have found that certain types of yarn may be efficiently cleaned when rigidly mounted blades are used in combinationV with the surface 20. I Wish it understood, therefore, that my invention in its broadest aspect includes the use of blades so mounted; and, in other respects, also, is by no means limited to the specific form and arrangement of the parts of the illustrative embodiment Whichlhas been described.

Certain features of the device illustrated and described in this application form a part of the subject matter of my co-pending applications Serial No. 582,384, filed August 17, 1922, and Serial No. 671,745 filed Oct. se, 1923.
