Hm! E. VAN HESS, OF ELMIRA, NEW YORK.

YARN CLEANER.

Application filed 1mm 2a, 1922. Serial No. 541,596.

To all whom it may concern:

Be it known, that I, HENRY E. VAN-Nnss,

understood, I will describe in detail a yarn cleaner embodying the invention which is a citizen of the United States, residin at illustrated in the accompanying drawings, Elmira, in the county of Chemung and tate in which of New York, have invented certain new and useful Improvements in Yarn Cleaners, fully described and represented in the following specification and the accompanying vdrawingls, forming a. part of the same.

his invention relates to yarn cleaners for eliminating from yarn impurities such as parts of seeds, parts of stems, slubs, specks, grains of sand, and other particles before the yarn is made into cloth, and thus improving the quality of the cloth made from the yarn and avoiding the necessity for excessive bleaching of the cloth.

An object of the invention is to provide a device adapted thoroughly to clean a traveling yarn without retarding the travel of the yarn, so that danger of breaking of the yarn in the cleaner is eliminated.

A further object of the invention is to provide a yarn cleaner adapted to discharge the particles removed from the yarn, without the use of anymechanically-driven parts.

A still further object of the invention is to provide a yarn'cleaner including a plurality of cleaning elements so arranged that the yarn cannot be passed through the cleaner without being brought into operative relation with all the elements, thus insuring a thorough cleaning of the yarn regardless of carelessness on the part 0 the operator. Other objects and advantages of the invention are hereinafter pointed out in connection with a detailed description of a specific embodiment of the invention.

A yarn cleaner embodying the invention and adapted to accomplish the objects above outlined may include a frame provided with a plurality of resiliently sup orted elements which are set into vibration y the travel of the yarn, and which, when vibrating, serve to 4 separate particles from the traveling yarn and to discharge the particles from the cleaner. The vibratory elements are most desirably arranged so that they all operate upon a yarn traveling in a straight line, and

5 the frame may be provided with a cover which insures {bringing the yarn into operative relation with all the elements when the cleaner is threaded.

In order that the invention may clearly be l 1 is a top view of the cleaner;

F1g. 7 is an enlarged perspective view of oneof the vibratory cleaning elements; and

Fig. 8 is a fragmentary perspective view of one of the vibratory cleaning elements looking toward the cleaning edge, one. still larger scale.

The cleaner shown in the drawings is adapted to operate upon a traveling yarn which is being drawn from a bobbin or other sup 1y into a winding or spooling or other mac nne. The cleaner may conveniently be secured to a portion of the frame of any such machine, and for this purpose there may be secured to the frame 10 of the cleaner a stud 11 containin a hole and provided with a set screw 12. t will be understood,'however, that the cleaner may be mounted in any desired manner and will'o crate upon any traveling yarn re ardless oi the nature of the machine into w ich the yarn is being drawn.

The frame 10 of the cleaner may be rectangular and the ends 13 and 14 of the frame may conveniently be made integral with one side 15 of the frame. For a reason hereinafter explained, 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 ma be varied, In the form shown, the side 16 as a dovetail connection with the ends 13 and 14 and is secured thereto by means of screws 17 which have'a threaded connection with the ends of the frame and pass through transverse slots 18 in the side 16, so that by loosening the screws the side 16 may be moved slightly toward or away from the side 15 of the frame.

On the end 13 of the frame, which I term the front end because it is the end from which the traveling yarn enters the cleaner, is mounted a tension device 19 of usual construction. The ends 13 and 14 are provided at their middles with recesses 20, 21 which permit a yarn A, which is passed over the tension device, to be drawn longitudinally across the middle of the frame, as indicated by the dotted lines in Figs. 1 and 2.

At the top of each of the sides 15 and 16 of the frame are long recesses 23. 22 which provide space for the mountings of the vibratory elements which are hereinafter described.

The top of the frame 10 is closed by a cover consisting of two pieces 26, 27 whose inner edges are spaced to provide a slot 28' adapted to permit the arn to be drawn into the position indicate by dotted lines in Figs. 1 and 2. The cover pieces 26 and 27 are secured to the frame by means of screws 25 entering the ends of the frame and projections 29, 30 on the sides 15, 16 of the frame between the recesses 23 and the recesses 22.

A skirt 32 extends downwardly from the frame to confine the particles and any matter removed from the yarn b the cleaner. The

- skirt 32 may convenient y be formed of a single piece of metal and secured to the ends 13, 14 and the side 15 of the frame by screws 33.. The skirt 32 is not attached to the side 16 of the frame and the skirt is of sufficient width to allow for the adjustment of the side 16 which is provided by the slots 18.

The vibratory cleaning elements 50, 50 extend inwardly from the sides 15, 16 of the frame. Each cleaning element may conveniently be formed from a single piece of sheet metal as shown. The thickness of the sheet metal is somewhat exaggerated in the drawin s for the sake of clearness.

ach vibratory cleaning element 50 comprises a cleaning blade 53 and a resilient support 52. The outer end portion 54 of the support 52 is set in a transverse slot 51 extending downwardly from the bottom of one of the recesses 23 in the side of the frame. The support 52 extends inwardly from the side 15 of the frame and it is inclined toward the back end 14 of the frame. The blade 53 extends inwardly from the inner end of the support 52 and is inclined toward the front end 13 of the frame. The inclinations of the support 52 and the blade 53 are such that the inner end of the blade 53 is substantially in line with the outer end portion 54 of the support 52.

The outer end portion 54 of the support 52 is held in its slot 51 by means of a washer 55 which is forced down by a screw 56 (see Fig. 5). The recesses 23 1n the side 15 of the frame provide space for the washers and the heads of the screws 56 below the lower surface of the cover piece 26. The outer end portion 54 is off-set from the remainder of the support 52, so that the top of the element lies close to the lower surface of the cover piece 26. A slight clearance is, however, allowed between the cleaning elements and the cover so as to leave them free to vibrate.

In the end of the cleaning blade 53 of each element 50 is a semi-circular notch 57 extending parallel to the sides of the frame. For convenience in threading, the upper portion 58 of the end above the groove 57 is also made parallel to the sides of the frame and is rounded off at its upper corner 59. In the form illustrated the lower portion 60 of the end below the groove 57 is also made parallel to the sides of the frame. The surface of the notch 57 and the front surface 61 of the blade 53 intersect in an acute edge 62, which I term the cleaning edge.

The cleaning elements 50 which are mounted on the side 16 of the frame are similar in form to the cleaning elements 50, and in the drawings the parts of the elements 50 are designated by the same numerals as the corresponding parts of the elements 50, a prime being added to each numeral.

The cleaning elements 50, 50' are arranged in the frame in staggered relation as illustrated. The inner ends of the elements 50 he in a common plane and the notches 57 are aligned. The inner ends of the elements 50 lie in a common plane and the notches 57' are aligned. When the cleaner is adjusted for cleaning yarns of diameters substantially equal to that of the notches 57, 57, the distance between the sides 15 and 16 of the frame 10 is adjusted so that the planes in which the inner ends of the cleaning elements 50 and 50 lie are coincident and the centers of the notches 57, 57 lie on a straight line, which is the line of travel of the yarn A through the cleaner.

The notches 57 and the cleaning edges 62 of the elements 50 surround. one-half of the circumference of the yarn A, while the notches 57 and the cleaning edges 62' of the elements 50' surround the other half of the circumference of the yarn. Each cleaning element is free to vibrate through the bending of its resilient portion. hen the elements are in vibration, the center point of the cleaning edge of each element moves in a plane including the line of travel of the yarn and in a curve tangential to the yarn. Consequently, the movement of each cleaning edge is substantially longitudinal of the yarn, although in the normal position of each element its cleaning edge is means:

slightly closer to the yarn than in the other positions which the element occupies durin its vibration. Thus, in the form illustrated the movement of each cleaning edge has, in addition to the relatively large component longitudinal of the yarn, the re atively small component transverse to the line of travel of the yarn.

I have found that the vibratory cleaning elements arranged in the manner described are efiective to detach from the yarn, particles adhering to it, and that the front surfaces 61, 61' of blades 53 of the elements tend to deflect these particles away from the line of travel of the yarn. I have found also, however, that a certain amount of fibrous material is necessarily removed from the yarn with the particles and that this fibrous material has a tendency to become re-entwined in the yarn after the particle has been detached from the yarn unless some means are provided for moving it to some distance from the yarn. Various means may be used for this purpose in cooperation with the cleaning elements, such as have been described. Thus, for example, air suction may be used for this purpose.

Vibratory deflecting elements 70, are, however, the most satisfactory and economical means which I have found for moving the particles and any adhering fibrous matter to a safe distance from the yarn. These deflecting elements constitute a part of my invention. Each deflecting element may conveniently be formed from a sin le piece of sheet metal as shown. The thic ass of the sheet material is somewhat exaggerated in the drawings for the sake of clearness.

Each deflectin element 70 comprises a blade 73 in a resi lent sup rt 7 2. The outer end portion 74 of the resllient support 72 is set in a transverse slot 71 in the side 15 of the frame inthe same manner that the supports of the cleaning element 50 are set in the slots 51. tends straight inward from the side 15 of the frame, while the blade 73 extends transversely to the line of travel of the yarn and is inclined rearwardly and downwardly. The blade 73 may be curved as shown, or to a greater or less degree, or may be flat. The blade 7 3 has an inner edge which is transverse to the resilient support 72 and is inclined to the line of travel of the yarn by reason of the inclination of the blade. The outer end portion 7% of the support 72 is off-set downward from the remainder of the support, so that the top of the element lies close to the lower surface of the cover piece 26. A slight clearance is, however, allowed so as to leave theelement free to vibrate. To facilitate threading, the upper corner of the inner edge 75 of the element is rounded 05 at 79.

The deflecting elements 70' are similar in The resilient support 72 ex-' form to the elements 7 0, and in the drawings the arts of the elements 70' are designa by t e same numerals as the corresponding parts of the elements 70, a prime being added to each numeral.

The deflecting elements 70, 70' are ar-' ranged in the rame in airs, each of the elements 70' being directly opposite one of the elements 70. The inner edges 75, 75' of each pair of deflectin elements are spaced apart by a distance'su tantially ual to the diameter of the yarn A so that t ey lie ad acent to the yarn on op osite'sides thereof. The inner edges 75, 5 may, in their normal posltion, be parallel, asmhown, or may, 1n certain cases, recede from one another, below the line of travel of the yarn, to assist in the clear-i1 of accumulated matter from the opening tween them. Each deflectin element is free to vibrate thr the hen ng of its resilient portion. en the elements are in vibration the points of their inner edges which are normally immedlately adjacent to the yarn-move in a plane including the line of travel of the yarn and in curves tangential to the yarn. Consequently the movement of each inner ed e is substantially longitudinal of the yarn, a though in the-normal position of each 1 air of deflecting elements their cleaning -1 1' are slightly closer together than in the ot er positions which the elements occupy during their vibration.

In the vibration of the deflecting elements 70, 70' the blades 73, 73' of each pair of elements turn outwardly from each other through the bending of the resilient supports 72, 72' of the elements. This turne mg movement is horizontal. Since the blades 73, 73' are oblique, that is, not perpendicular, to the direction of the turnin movement, the inner edges 75, 75' of eac pair of the blades 73, 7 3' are separated from each other to a greater extent at their lower ends than at their upper ends when the blades are turned outwardly from each other.

Behind each pair ofdeflecting elements is a pin 80 having one of its ends fi'xed in the side 15 of the frame. The upper surfaces of these pins lie in a plane tangential to the notches 57, 57 at their lower corners, so that the pins aid in placing the yarn in operative relation tothe cleaning edges 62, 62 when the cleaner is threaded, and serve to prevent the yarn from dropping below the notches 57, 57' in case the yarn is slackened. The use of the cleaner is as follows: The cleaner is first adjusted in accordance with the diameter of the yarn in connection with which it is to be used. The adjustment is effected by loosening the screws 17 and moving the side 16 of the frame slightly inwardly or outwardly. If the diameter of the yarn is substantially &

equal to that of the notches 57, 57', the side 16 is positioned as shown in the drawing so as to bring the centers of the notches 57 on a line with the centers of the notches 57. Owing to the compressibility of the yarn, yarns whose diameters vary somewhat from that of the notches 57, 57' may be successfully cleaned in the device adjusted as illustrated. If, however, the diameter of-the yarn is materially different from that of the notches, the cleaner should be adjusted so that the cleaning edges 62, 62' surround the yarn as closely as possible. This is done by moving the side 16 of the frame sli htly inwardly if a smaller yarn is to be c eaned, or slightly outwardly if a larger yarn is to be cleaned.

The cleaner is threaded by drawing the yarn through the tension device 19, extending it across the top of the cleaner and then drawing it down into the slot 28 be tween the two cover pieces 26, 27. As the yarn is drawn down it is guided to the center of the frame by the rounded corners 59 of the cleanin elements and the rounded corners 7 9 of the deflecting elements. The yarn is pulled forward while it is drawn downwardly, and the forward movement of the warn pulls each of the vibratory clean,- ing elements backward, thus causing the upper portions 58, 58 of the ends of these elements to move outwardly from their normal position, permitting the yarn to be drawn by them and into the notches 57, 57 The pins 80 prevent it from being drawn below the notches. The yarn then extends throu h the cleaner in a straight line and may be drawn forward by a winding or other machine not shown in the drawings.

In the operation of the cleaner, the vibratory cleaning and deflecting elements are set into vibration by the passage of the yarn across their edges and more particularly by the impingement against their'edges of particles projecting from the yarn. As the cleaning elements 50, 50 vibrate, the cleaning edges 62, 62' of these elements strike particles projecting from the yarn and brush them from the yarn. If a particle is firmly entwined in the yarn it is usually not removed from the yarn by the first cleaning element which strikes it, but is merely loosened so that it may be detached by a subsequent cleaning element. The particles which have been detached from the yarn and any fibrous matter which may adhere to them tend to be drawn along in the direction of travel of the yarn by the suction produced by the movement of the yarn. These particles and this fibrous matter strike the deflecting elements 70, and are directed downwardly inside the skirt 32, so that they do not become again entwined in the yarn. The portions of the inner edges of the deflecting elements which The particles 7 ins because the deflecting here to the elements positioned in front of each of the pins protect the pins. As a result all the particles and any fibrous matter removed from the yarn is directed downwardly within the skirt 32 and maybe collected in any desired manner at the bottom of the skirt.

I wish it clearly understood that my invention is by no means limited to the particular form and arrangement of parts which I have described.
