16 Claims.

This invention relates to a yarn cleaner and more particularly to a yarn cleaner which is readily adjusted to clean yarn and like of different sizes, and which may be reset and adjusted to compensate for Wear.

In the textile and other arts employing yarns of various kinds, it is important that the yarn be of substantially uniform size throughout and that it be cleaned and free from lint, and enlarged portions know'ngenerally in the trade as slubs.

Heretofore in practical processing, one common practice has been to provide a separate cleaner plate having the correct size of guiding and cleaning slot or aperture for each size of yarn. After a period of use the guiding or gauging edges become worn and at times become worn to an irregular or somewhat saw tooth form, and no means are provided for resetting the cleaning and guiding edges. It then becomes necessary to remove the worn cleaner plate and replace it. To replace an old cleaner or to change to one of a different size involves a certain amount of trouble and the expenditure of time. In accordance with another practice, where the entire cleaner and guide plate is not replaced, an attempt has been made to obtain a degree of adjustability by providing a guide or cleaning slot or aperture in which one of the guides is fixed in position by screws or the like in such a way that slight movement of the guide may be obtained to vary the size of the slot or aperture. However, such an arrangement is rather crude, inconvenient and uncertain, and does not provide, with convenience and certainty, the adjustability desired.

One of the objects of the present invention is to provide a readily adjustable yarn cleaner and gauging device which will overcome the objections and difficulties above referred to inherent in the devices usually employed in practice, and which will have additional new and distinctive advantages thereover in convenience of application and precision and definiteness in adjustability to different sizes of yarns and to compensate for Wear.

A further object of this invention is to provide a yarn cleaner in which either one or both of the cleaner guides may be conveniently replaced when worn out. p

A further object is to provide in a yarn cleaner, an adjustable means by which a visible index may be afforded in adjusting the yarn aperture to any size or to compensate for wear.

A further object is to provide in a readily adjustable yarn cleaner means for securely fixing or looking the control means in position to prevent accidental displacement and to prevent unauthorized persons from varying the adjustment.

In general the above objects are accomplished by providing a plurality of independently movable guides, a manually controlled means, and motion transmitting means or connection interposed between the manual control and one of the relatively adjustable guides, said manual control preferably having a position fixing means and a graduated index or scale associated therewith for 10 convenience and definiteness in setting the yarn guides to a particular size of yarn.

One selected embodiment is shown and described in the accompanying drawing and following description for purposes of illustration, it be- 15 ing understood that various changes and modifications in detail construction and arrangement of parts may be made without departing from the invention as claimed.

As shown in the illustrated form the yarn cleaner comprises a main body or supporting frame I which may be of any suitableform. One portion of the frame is shown as. a quadrant having a notched or knurled arcuate perimeter 2 which is adapted to cooperate with a position fixing (Fig. '10) or looking (Fig. 13) mechanism, to be hereinafter more fully described, carried in the head 3 of a manually actuated arm 4 which is pivotally mounted in the frame I on a stud 5 having an eccentric cam 6 the purpose and function of which will hereinafter be more fully described. A slotted aperture through which the yarn 8 is passed is formed by the guides 9, It formed integral with the frame. The open end of the yarn aperture or slot preferably terminates in an outwardly tapering mouth or lead H to facilitate the leading of the yarn in the aperture 1. Preferably the other or inner end of the yarn aperture l terminates in an enlarged circular aperture l2 which facilitates freeing and clearing the main aperture 7 of lint or slubs there collected. The actual cleaning and gauging of the yarn passed through the slot 7 is performed not by the fixed integral guides 9, It but by a pair of relatively adjustable cleaning'guides is, M, the edges of which extend beyond the edges of the integral guides 9, l0.

Preferably the yarn cleaner guides l3, id are made relatively adjustable to accommodate yarn of different sizes and to compensate for wear, by having'one of the cleaner guides M, for example, so arranged as to be movable and adjustable relative the other guide 53 which preferably may be detachably fixed in position by screws or other suitable means. Such a construction makes possible the ready replacement of either one or both of the functioning yarn cleaner guides it, Hi. If

the diameter of the cam 5.

desired other arrangements may be employed to effect the relative adjustability between the cleaner guides such for example as where both of the guides are movable. If desired the relatively fixed guide lEl integral with the frame may be used with the adjustable guide Hi to form the yarn cleaning slot.

The movement of the adjustable guide I4 is effected by the motion transmitting connection which is actuated by the manual controlled member or arm 4. guide I4 is provided with a projecting portion which is shown as a portion integral with the guide H4. The two portions l4 and 15 form a flat plate of generally L. shape, it being understood however other arrangements and forms may be used. A cam receiving aperture i6 is formed in the portion [5 of the movable guide M, and is of such form and size'as to receive the eccentric came which is eccentrically mounted on the stud 5. The cam ii and the plate [5 are preferably of substantially the same thickness (see Fig. 6) which forms a neat compact feature of construction. Preferably the width of the aperture l 6 in the portion l5 of the guide is'such. that sides I! and is contact with opposite sides of theeccentrically mounted cam 55. In this way a positive movement of the guides l4, i5 is effected in either direction. The other two sides i9, 28 of the aperture are preferably spaced a greater distance' apart to accommodate the enlarged eccentric portion ofthe cam 65, as the arm 4 is moved to rotate the stud 5 through a portion of a revolution. r

If desired a spring 2! may be suitably disposed so as to cooperate with the portion l 5 of the guide M. to take up any lost motion, or wear of parts, and thus maintain constant contact between the cam ii and the side ll of the aperture. The spring 2! is particularly useful if the distance between the sides H, 98 of the aperture i6 is greater than As shown, the end of the spring 2| is fixed in a slot in the frame I In the illustrated form shown the but other desired arrangement may be used for locating the spring.

The movement of the stud 5 for actuating the cam 6 is effected through the bifurcated arm 4 having its ends mounted upon the opposite ends of the stud 5. Preferably the stud 5 is fiattened in one or more planes and the apertures in the arm 4, 4 and the indicator 22 correspond in shape thereto so as to move with the stud. The arms 4, 4 straddle the frame I and are connected at their outer ends by the bridging handle or knob 3] The arm 4 located on the front face of the frame is preferably provided with an aperture 23 through which the pointer or indicator hand 22 may be observed in its relation to the graduated dial 24 which is preferably provided on the front face'of the frame. The indicator hand 22 is'mounted on the stud 5 so as to rotate therewith andindicate in cooperation with the dial 24 the extent or size of the yarn cleaning aperture between the cleaner guides 13, I4.

A transparent covering 25 (Fig. 6) for the front face of the frame is preferably disposed between the arm 4 and the indicator hand 22. The covering 25 is provided with a bearing aperture to receive the stud 5.

The functioning parts of the cleaner are pro tected and enclosed by a removable back or cover 26 which may be removably fixed in position on the back of the frame by screws 27, 21 (Fig. 2). The rear cover is preferably provided with a bearing aperture to receive the end of the stud which extends therethrough and on which the arm 4 is mounted.

As a means of maintaining the manually controlled guide adjusting arm in relatively fixed adjusted position, a detent Zdis pressed by a spring 29 against the notched or knurled edge 2 of the frame, (Fig. 10). parts are carried in the cap or handle portion 3 of the arm 4, 4 In certain instances in the yarn cleaning operation it is desirable to have the manual actuating control arm more securely locked in position so that the operator of the machine is not tempted to enlarge the yarn cleaning slot or aperture to pass a slub or other enlarged obstruction on the yarn, instead of removing or cutting out the slub and re-tying the yarn. In such instance an arm lock such as that shown in Fig. 13 may be employed in which a plug 3% is shown threaded in the cap portion 3 and a head 3! of special form is provided for the plug, said head 3| being recessed or countersunk below the rim of the cap 3 so as to be inaccessible except to an authorized person having the necessary tool or wrench. The stem 32 engages the notched edge 2 of the frame and securely locks the arm 4, 4 and the guide l4 controlled thereby in a fixed position.

While one preferred form has been shown and described it is understood that various changes and modifications in arrangement and details of construction may be made without departing from the spirit and scope of the invention as defined in the appended claims.
