Patented March 16, 1909. 1907. Serial No. 386,261.

To all whom it may concern:

Be it known that WB,-JAMES R. MAoCoLL and WILLIAM B. MACCOLL, citizens of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Imrovement in Yarn-Cleaners for Spoolers, pinning, or Similar Machines, of which the following is a specification.

This invention has reference to an improvement in spoolers, spinning or similar machines or more particularly to an improvement in yarn cleaners for removing the slubs, knots or similar enlargements liable to occur on yarn or roving.

The object of ourinvention is to improve the construction of a yarn cleaner for spool ers or similar machines, whereby slubs, knot or bunches on the yarn are removed from the yarn more com iletely than has heretofore been done,

there the yarn or cloth.

The invention consists broadly in a yarn cleaner having means for sosup orting slubs or beads during the passage of t e'yarn y improving the quality of beneath the comb teeth that said teeth act 3 ick the slubs or beads from the yarn 'wit out necessarily acting directly on the yarn. g

The invention also consists in the eculiar combination of the yarn guide and s ub support with the comb whereby at the point at which the comb is designed to engage a slub or bead the yarn diverges from such oint of enga ement and, while the slub or ead is he d y the teeth of the comb the yarn-is drawn laterally as well as longitudinally awagfrom the slub so held. v

T e invention also consists in such other novel features of construction and combination of parts as shall hereinafter be more fully described and pointed out in the claims.

Figure 1 is a vertical side view of our improved y'arn cleaner in its operative position on the traverse rod of a spooler and showing the yarn in the position it would assume in passing through the cleaner. Fig. 2 is a top plan view of the cleaner showing the yarn in its normal position in full lines and theposition in which the yarn is placed to thread the cleaner in broken lines, and Fig. 3 is a vertical sectional view taken on line 3 3 of Fig. 1, showing the means of adjusting the central guide rod of the yarn cleaner.

In the drawings, 0 indicates a portion of a traverse rod of a spooler or similar machine,

I) the yarn and 0 our improved yarn cleaner. The yarn cleaner 0 consists of a frame member 4 having a downwardly-extending jawshaped arm 5 in the upper edgeof which is a semi-circular notch 6 for the traverse rod a, a horizontal arm 7 to the side of which is secured an inner guide rod 8 parallel with the traverse rod a and having an upwardlyrounded end 9, an outer guide rod 10 parallel with the inner guide rod and having an upwardly-rounded end 11, and a longer and heavier central uide rod 12 laced intermediate and para el with the 1111181 and outer guide rodsand having a smaller eccentric screw-threaded end 13 which screws through the arm 7, has a transverse slot 14 in its end and is held in the adjusted position by a set screw 15 in the arm 7, as shown in Fig. 3.

An u wardly and outwardly extending curved racket 16 is formed on the upper ed e of the arm 7 and has the arm 17 set at rig t angles to the bracket 16, overrthe cen tral guide rod 12 and arallel with the guide rod. This arm 17 is a so set at an angle relative to a vertical line, and a comb 18 having the needle teeth 19 and the back 20 in which are the vertical slots 21 21 adjacent the ends of the back, is adjustably secured to the inclined face of the arm 17 by the screws 22 22 which extend throughthe slots 21 21 in the comb and screw into the arm 17, as shown in Figs. 1 and 2, and a jaw-shaped member 23 having a semi-circular notch 24 for the traverse rod a is secured to the jaw-shaped arm 5 by a fastening bolt 25 which extends through a hole in the j aw-sha ed member 23, screws into the arm 5 and 0 amps the yarn Fig. 1.

The yam cleaner cis clamped to the traverse. bara by the bolt 25in a position to bring the guide rods 8, 10 and 12 on a horizontal line, as shown in Fig. 1. The yarn b is threaded through the cleaner 0 by placing the yarn over the end of the centra guide bar 12, as shown in broken lines in 'Fig. 2, when the draft on the yarn will pull the same rods 8 and 10 and into its normal central 0- sition, as shown in full lines in Figs. 1 an 2. The comb 18 is adjustable on the arm 17 and held in the adjusted position by the screws 22 22, and the central guide rod 12 is adjusted to raise or lower the yarn by turning cleaner 0 to the traverse bar a, as shown in under the curved ends 9 and Not the guide the guide rod with a screw driver until the yarn just clears the points of the teeth 19 on the comb 18 and he (1 in the adjusted position by the set screw 15, as shownin Fig. 3.

The yarn 7) moving in the direction of the arrow, as shown in Fig. 1, passes over the traverse bar a, under the inner guide rod 8 over the central guide rod 12, just clearing the points of the teeth 19 on the comb 18 and then under the outer guide rod 10. The guide rods act as a slight tension on the yarn, stretching the yarn over the central guide rod, and when a slub, knot or bunch of any kind occurs in the yarn, it is effectively removed by the teeth 19 on the comb 1S.

Attention is called to the positions of the parts, as shown in Fig. 1, in which the comb 18 is inclined to'the path of the am and the comb teeth extend tangentia y with respect to the periphery of the guide 12 where by as the yarn passes over the guide 12 it is dlrected upward toward the points of the comb teeth as a result-of which the slubs or beads carried by the yarn are so supported in their passage over said guide 12 that, approximatelyv as the slubs are engaged by the points of the comb teeth, the thread oryarn diverges from the slubs or beads whereby the slubs or beads are, in efiect, picked up by the comb teeth from the peri hery of the guide 12 and said comb teeth 0 not necessarily effect'a combing engagement with the thread or yarn. By this peculiar cleaning action the thread or yarn is subjected to compai atively little stl ain by the comb teeth, and said teeth are adapted to receive and retain successive slubs, fibers or beads, those first taken by said teeth being forced upward ontlie teeth b the succeeding slubs. The central guide ro 12 forms'a support on which the yarn passing thereover may move laterally as the diameter of .the spool for receiving the yarn increases with the added layers of yarn wound thereon. In this lateral movement of the yarn it is brought constantl beneath a clean portion of the comb 18 an if a bead or slub carried forward b the yarn is engaged by the comb teeth, such lateral movement tends to disengage the yarn from said slub or bead, whereas, if the yarn followed one course, the slub or bead engaged by the comb teeth might act to engage the loose fibers carried forward by the yarn until the accumulated fiber eifectsthe reaking of the yarn. I It is evident that our improved yarn cleaner may be used on spoolers, spinning frames or similar machines and that the comb 18 may ,be set at any angle desired Without materially affecting the spirit of our invention. v

It is obvious thatthis improved cleaner may be used to clean other materials than those known specifically as yarn, roving etc. The extension of the support across the path of the material to be cleaned and the combination therewith of the comb or cleaning element having a series of teeth extending;

at an angle with said support and haying the points of said teeth arranged in a line parallel to said support may be advantageously utilized in cleaning other materials.

Having thus described our invention, we

claim as new and desire to secure by Letters 1 Patent 1. A yarn cleaner comprising a comb fixed with reference to the movement of the material to be cleaned, and means for guiding saidmaterial in a path diverging from the direction in which the comb teeth extend said guiding means extending laterally parallel to a lurality of said comb teeth and transverse y to the path of the yarn whereby the yarn may move laterally with respect to said row of teeth as and for the purpose.

described.
