removing impurities from traveling yarns,

andaims `toprovide a simple and effective device for detaching specks and other impurities from a traveling yarn which auto-- matically adjusts itself for yarns of differentsizes.

The invention is particularly adapted for use in the scraping type ot' yarn cleaner in which a traveling yarn is drawn between two opposed members, one or both of which exert ka scraping action on it. In accordance with thel present invention, one of the two opposed members is mounted so as to be movable with respect to the other during the operation of the cleaner. The movable'member has a mass such that its inertia prevents it from making other than very slight outward movementsA when urged outwardly by arregularities on the yarn. The movable member is constantly urged inwardly toward the yarn by a torce very much less than its weight. Consequently, after it has been moved slightly outward by irregularities of the yarn, it moves inwardly .against the yarn again, but with a force so slight that it does not exert undue pressure on the yarn which would tend to tear it.

This construction, besides having the important advantage of-making the cleaner selfadjusting for yarns of different sizes, has the additional advantage of increasing the ef- Aiectiveness of the cleaning because of the slight inward and outward vibration of the movable member which occurs when the device is in operation.

The nature of the invention` may be more fully understood from a detailed description of the three embodiments of it which are illustrated in the accompanying drawings, 'in which:

Fig. 7 is aside view of the cleaner shown in Fig. 6 looking in the direction of the arrow 7 in Fi g. 8 and showing the frame of the cleaner sectioned on the line of travel of the Fig. l0 is a transverse section similar tov Fig. 5 showing a third cleaner embodying the invention; and

F ig. ll is a transverse section similar to Fig. 5 showing a fourth cleaner embodying the invention.

The yarn cleaners illustrated are intended to operate upon a traveling yarn which is being drawn from a bobbin or cone ,into a winding, spooling, or other machine. The cleaners may be conveniently secured to a portion of the frame of any such machine.

The yarn cleaners shown in Figs. l to 5 inclusive are provided with a supporting bar 10 having a bracket l1, in the lower edge of which is a vertical slot adapted. to fit over a horizontal bar B forming a part ofthe frame of a winding or other machine. A set screw 12 is provided to hold the supporting bar 10 iirmlyon the bar B.v The mounting is such that the upper surface ofthe supporting bar is in a horizontal plane. One of the side surfaces 13, which, for convenience, -is\ termed its inner side,A is inclined at-an angle of about 15 to the vertical.

To the inclined surface 13 of the supporting bar 10 is attached the fixed side member 20 of the frame of the yarn cleaner. The attachment may be by means of screws 16.

'The frame of the yarn cleaner has also a tangular in' cross section, and studs 17 pro of about to the horizontal.

' with one of the blades 21, and the blades are provided with opposed scraping edges 23, 33..

As, appears most plainly in Fig. 5, the scrap- Y ing edges 23, 33 of each pair of blades have j the table 44 and under the slub catcher and then over the thread guide,

middle `portions 24, 34 which are substantially parallel and have outwardly curved upper portions 25, 35' and outwardly curved lower portions 26, 36. One set of the scraping edges, for example, the set 23, are provided with small aligned notches 27 located at the upper ends of the intermediate portions 24. The lower edges of these notches are aligned with the upper surfaces of the studs 17 and the up er surface of a pin 18 projecting from the Xed side member 20.

In order to guide a. yarn A between the scraping edges 23, 33, thread guides 40, 41

are provided at opposite ends ofthe frame ofA the'cleaner, being supportedon brackets projecting inwardly from the supporting bar 10. A tension device 42 is also provided on the front thread guide 40, and an adjustable slub catcher 43 may be provided between the thread guide 41 in the rear end of the frame of the cleaner. In the form shown, the slub catcher 43consists of a table44 formed ona bracket projecting inwardly from the supporting ar 10 and a blade 45 carried by a bracket 46 rojecting inwardly from the upper art o? the bar I0. The u per portion 47 o the bar 10 to which the racket 46 is attached is separated from the main portion of the bar by a slot 48, so that it may be moved up and down by means of an ad.

]usting screw 49 to varythe distance between' the blade and the table 44.

The use and operation of the cleaner as described is as follows The cleaner is threaded by passing a yarn A through the thread guide 40 and under the tension device 42 and dropping it into 'the space provided between the curved upper portions 25, 35 of the scraping edges 23, 33 of the blades passing it over time 45,0f the 41. As soon as a pull is applied tothe yarn beyond the thread guide 41, the yarn is drawn down until it strikes the studs 17 and pin 18, and' is thus positioned between the notches 27 of the blades 21 and scraping edges 330i the blades 31. As the yarn is thus drawn down, it, of course, causes a slight outward iyrzaasej movement of the movable side member 30 and its blades 31; for, before the cleaner is threaded. the movable member 30 slides in so that the intermediate portions 34 of the scraping edges are in Contact with the intermediate portions 24 of the fixed scraping edges. j

In the operation of the cleaner, the yarn is drawn from left to right (Figs. 1, 2, As' the yarn is drawn through the cleaner, the specks and other impurities which it contains and a slight amount of fibrous matter, are scraped from it by the blades. The particles removed, which are, of course, traveling rapidly in the same direction as the yarn when they are scraped off, are directed downwardly by the lower portions of the blades. During the travel of the' yarn, specks and other slight irregularities of the yarn cause frequent and irregular forces on the blades 31 carried by the movable member 30, which set this member and its blades into an inward and outward reciprocation of very small amplitude. This reciprocation, or vibration as it may be termed, tends to keep the blades clear of fibrous matter. At not infrequent intervals. the reciprocation is Kmomentarily of sufiicient amplitude to permit the yarn to slip out of the notches 27 and move `downwardly between the blade edges, thus clearing out any fibrous matter or particles which may have been caughtbetween the blade edges belowthe yarn.

' It is apparent from the above description that the cleaner which is described is self- 10u adjusting for yarnsiof4 different sizes, since the distance between the opposed scraping edges is determined by the yarn itself. `It is, however, sometimes desirable to providethe device also with a manual adjustment, limiting the extent to which the opposed scraping edges may approach one another. Such an adjustment is provided in the cleaner illustrated by screws 5() and threaded in tapped holes'in the studs 17 and stops 51 110 formed on brackets 52 attached to the movable member 30 and adapted to limit the inward movement of the yarn by engagement with the heads of the screws 50. The heads Jof' thesescrews .serve to prevent accidental 115 removal `of the side member 30 from the studs 17.

The yarn cleaner shown in Figs. 6 to.9 inclusive is similar to that already described, except that its movable side 30 carries no 120 blades, but instead is provided with a smooth surface 31 opposed to the scraping edges v23 of the blades 21. l Av detailed description of this cleaner is unnecessary as its construction is ap arent from Figs. 6 to 9 of the draw- 125 Y springs 53 reacting between heads 54 at the ends of the studs 172 and the outer surface of the movable side member 302, urging l said member inwardlywith a force which is equal to only a small fraction of its weight.

It is apparent that the operation 'of this cleaner is substantially like that of the lirst cleaner. described.

The cleaner shown in Fig. 11 is similar to that-'shown in Fig. 10 except that both of its side :members 203 and 303 are movable. The two side members are slidably mounted on long studs 173 projecting horizontally from the supporting bar l0. The side members are urged towards each other by long light compression springs 53', 54 each of which exerts the force equal to only7 a small fractlon of the weight of the side member against which 1t re-acts. Y

What I claim is:

1. A yarn cleaner for removing particles from a trad/ cling yarn, comprisingl opposed separable members at opposite sides of the yarn, atleast one of which is provided with transverse scraping edges, and means for yieldably urging one of said membersagainst the yarn by a force materially less than the Weight of the movable parts of the cleaner.

2. A yarn cleaner for removing particles from a traveling yarcn, comprising a frame member at one side of the yarn, a massive movable' member opposed thereto -at the other side of the yarn, at least onef'of said members being provided. with transverse scraping edges,.and the movable member being yieldably urged against the yarn by a force materially less than the weight of the movabley` member. v

3. A yarn cleaner for removing particles from a traveling yarn, comprising a framemember at one side of the yarn, a massive movable member opposed thereto at the other `side of the yarn, bot-h of said members being provided with aligned transverse scraping edges, and the movablemember being yieldably urged against the yarn by a force materially less vthan the weight ofv the movable member.

4. A yarn cleaner for removing particles from a traveling yarn, comprising opposed movable members at opposite sides of the yarn, at least one of which is provided with transverse scraping edges, and means for a force so slight that the travel of the Vyarn between the scraping edges causes inward and outward vibration of the blades.

6. A yarn cleaner for removing particles from a traveling yarn, comprising a plurality of pairs of transverse blades having opposed scraping edges between which the yarn is drawn, the blades of each pair lying in a common plane, and a mounting for said blades permitting a separating movement of the blades of each pair in the common plane of said blades, and means for yieldably urging one blade in eachpair against the yarn.

7. A yarn cleaner for removing particles from`a traveling yarn, comprising avframe having relatively movable side bars, opposed transverse blades projecting from the inner surfaces ofthe side bars, one of said bars being yieldably 'urged toward the other with a force so slight that it and the blades which it carries are set into vibration by the movement of the yarn.

`In testimony whereof I have hereunto set my hand.
