Application fled July as, 1922. Serial ll'o. 571,402.

To all may cmwernr I Be it known'that I, HENRY VAN Nnss, a citizen of the United States, residin at in the county of Chemung and tate of. New York, have invented certain new and useful Improvements in Yarn Cleaners, fully described and representedin the following specification and the accompanying drawings forming a part of the same.

This invention relates to yarn cleaners for eliminating from yarn impurities of all sorts, as well as slubs and knots.

The invention relatesto the type of yarn cleaner described and claimed in my co ending applications, filed March 21, 1922, erial No. 547,596, and filed June 8, 1922, Serial .No. 566,722, (on which United States Pat ents Nos. 1,456,261 and 1,456,262 were issued 'to me on May 22, 1923) in which the cleaning is accomplished by a plurality of yieldably in securing'the end of one of the cover pieces to the frame in such manner that its distance from the other cover justed so as to vary the istance the inner edges of the rigid blades as desired. In order that the invention ma clearly be understood, IIwill describe in etail the specific embodiment of it which is shown in the accompanying drawings, in which Fig. 1 is a top view of the cleaner with a portion of the cover plates broken away;

Fig. 2 is a side view of the rear portion of-the cleaner sectioned on the line 2-2 of Fig. 1; and

Fig. 3 is a rear end view of the cleaner. The cleaner shown in the drawings is adapted to operate upon a traveling yarn which is being drawn from a bobbin or other V supply into a winding or spooling or other machine. The cleaner may conveniently mounted elements which are set into vibrabe secured to a portion of the frame of any tion by the travel of the yarn,and, when vibrating, serve to knock, brush and scrape off impurities adhering to the yarn, and to beat out impurities embedded in the yarn. I have found that when yarn cleaners of this type are used in connection with certain types of yarn, the yieldably mounted elements permit the passage of slubs and of knots of suflicient size to interfere with the operation of knitting or other machines in the yarn is to be used. The present invention aims to eliminate this difficulty.

A yarn cleaner constructed in accordance with the present invention includes yieldably mounted cleaning elements and also a pair of rigid blades having closely spaced inner edges which embrace the yarn. These edges are positioned so that they permit the passage of knots which are so flat and small that they will not cause difliculty in the knitting or other machines in which the yarn is to be used, while at the same time they cause the yarn to break when a slub, or a knot of suflicient size to cause trouble in the knitting machine, is drawn into the yarn cleaner.

A further feature of the invention consists in forming the rigid blades as integral extensions of two cover pieces placed over a frame in which the yieldably mounted elements are supported. In this way the advantages of the invention are obtained without adding additional parts to the yarn cleaner and without causing any additional trouble in threading the cleaner.

A still further feature of the invention lies ,such machine, and for this purpose there may be secured to one side of the frame 10 of the cleaner a stud 11 containing a hole and provided with aset screw 12. It will be understood, however, that the cleaner ma be mounted in any desired manner and wifi operate upon any traveling yarn regardless of the nature of the machine into which the yarn is being drawn.

The frame 10 of the cleaner may be rectangular, as shown, and the ends 13 and 14 of the frame may be made integralwith one side 15 of the frame. It is desirable to form the other side 16 of the frame. of a separate piece of metal, and to attach it to the ends 13, 14 in such manner that the distance between it and the side 15 of the frame may be varied.

The ends 13 and 14 of the frame are provided at their middles with recesses 20, 21 which permit a yarn A to be drawn longitudinally across the frame some distance below the upper edge of the framen-rTothe end 13 of the frame, which I term therfrontend because it is the end from which 'the tpiece ma be ad tween,

traveling yarn enters the cleaner, is atplies a drag to a yarn drawn across the plate under it. As the tension device illustrated forms part of the subject matter of my copending application, filed July 20. 1922, Serial N 0. 576,249, it is not described in detail, or claimed, in the present application.

In the frame 10 are mounted a plurality of cleaning elements. These elements include staggered forwardly inclined cleaning blades 53, and airs of rearwardly and downwardly inclined cleaning and deflecting blades 73. Each of the blades 53, 73 is yieldably mounted by means of a resilient supporting member 52 or 72, the outer end of which is secured in one of the sides 15 or Ii of the frame 10. The resilient members may be formed integral with the blades as shown.

The cleaning elements 53, 73 are enclosed by a casing which includes a skirt 25 secured to the outside of the frame 10 and depending therefrom, and a cover secured to the top of the frame 10 and consisting of two pieces 26, 27, whose inner edges are spaced some distance apart to provide a wide slot 28 extending from the recess 20 in the end 13 tothe recess 21 in the end 14. Blades 30, 31 extend rearwardly and downwardly from the rear edges of the cover pieces 26, 27, respectively. These blades are preferably formed as integral extensions of the cover pieces. So far as the operation of.

the cleaner is concerned, these blades may be re arded as rigid.

he blades 30, 31 are located outside the skirt 25, and the inner edges 32, 33 of the blades include between them a narrow slot 34 which is located behind the recess 21 of the rear end member 14 and substantially in alignment with the slots included between the pairs of yieldably mounted blades 7i. The inner edges of the blades 30, 31 include diverging portions 35, 36 providing an outwardly tapering space 37 at the inner end of the slot 34 connecting the slot 34 with the wider slot 28 between the cover pieces. These inner edges include also divergent portions 38, 39 providing an outwardly tapering space 40 at the outer end. of the slot 34.

The cover pieces 26, 27 are secured to the frame 10 in such manner that the width of the slot 34 between the blades 30, 31 may be adjusted as desired. In the form illustrated, the cover piece 27 is secured in fixed position upon the frame 10 by screws 45, 46 entering tapped holes in the ends 14, 13 of the frame and passing through round holes in the cover piece. The front end of the cover piece 26 is secured to the front end member 13 of the frame by a screw 47,

similar to the screws 45, 46. The rear end of the cover piece 26 is adjustably secured to the rear end member 14 of the frame 10 by means of a screw 48 which passes through a transverse slot 49 in the cover piece 26. It is apparent that if the screw 49 is loosened, the cover piece 26 may be turned about the screw 47 so as to vary the distance between the inner edges of the rigid blades 30 31.

In threading the cleaner which has described, the yarn A is dropped or drawn into the slot 28 between the inner edges of the cover pieces 26, 27, and pulled downwardly. As the yarn is pulled down, it is guided by the portions 35, 36 of the inner edges of the blades 30, 31 into the slot 34. It is drawn down until it occupies the position shown in the drawings, in which it extends longitudinally across the frame 10 at the level of the bottoms of the recesses 20, 21 and between the inner edges 32, 33 of the rigid blades 30, 31f The yarn is then drawn through the cleaner by a winding or other machine not shown in the drawings.

In the operation of the cleaner the yieldably mounted blades 53, 73 are set into vibration by the impingement of particles projecting from the yarn, and, when vibrating, serve to knock and scrape off particles adhering to the yarn, and to beat out particles embedded in the yarn. The blades 73 serve to direct the particles which have been removed downwardly into the space within the skirt 25. In cleaning certain kinds of yarn, the yielding of the plates 53 and 73 permits the passage of slubs and of knots of suflicient size to interfere with the operation of a knitting or other machine in which the yarn is to be used after it has been cleaned. Such slubs and knots are, however, caught against the inner edges of the rigid blades 30, 31 causing the yarn to break. The operator thus receives notice of the presence ofa slub or large knot and may break out the slub or large knot and retie the yarn with a flat knot which will not have a detrimental effect in a knitting or other machine. As the blades 31, 32 are located to the rear of the frame 10 and outside the skirt 25, it is not necessary to rc-thread the frame after the yarn has been re-tied. It is merely necessary to insert the pieced yarn in the slot 34 from the bottom. The diverging portions 38, 39 of the inner edges of the blades facilitate this operation.

The distance between the inner edges of the rigid blades 30, 31 is adjusted so that the blades permit the passage of flat knots which will not be injurious in knitting, but break the yarn when a large knot or slub is drawn against them. The blades are usually adjusted so that the distance between them is about equal to the diameter of the yarn.

' It should be clearly understood that the inventlon is by no means limited to the Ben specific mechanical features of the embodiment which has been illustrated, except in so far as these features are specified in the claims which follow.

What is claimed is:

1. A -yarn cleaner, comprising the combination of a-plurality of transverse blades yieldably mounted for movement having a component in the direction of travel of the yarn and a component away from the yarn so that they permit the passa e of knots and slubs, and a pair of rlgid lades embracing the yarn and adapted to catch knots or slubs upon the yarn.

2. A yarn cleaner, comprising the combination of a plurality of transverse blades yieldably mounted for movement having a component in the direction of travel of the yarn and a component away from the yarn so that they permit the passage of knots and slubs, a pair of rigid blades embracing the yarn, and means for adjusting the distance between the inner edges of said rigid blades so as to cause them to break the yarn when a knot or slub exceeding a predetermined size is drawn against them.
