CONED YARN SUPPORT Filed Feb. 24, 1934 2 Sheets-Sheet 2 INVENTOR CARL EFFJ ATTORNEYS Patented Dem '18, 1934 llarl iEpps, home, Ga... assignor to 'llubine @hatillon Corporation, a corporation oi? idola- This invention relates to yarn support devices, particularly devices employed. to support cones,

bobbins or cops of yarn undergoing unwinding.-

Manufacturers of yarn, strands, thread and the like ordinarily wind the same on cones, bobbins, cops oi similar holders. In the case of so= called coned yarn, the yarn is generally wound on a paper or pasteboard'cone; reallya frustum of a cone. During the making oi textile fabrics, for example, hosiery, the coned yarn is unwound, usually directly to the knitting machine itself. Various devices are employed to support the coned yarn. It is customarily supported on a spindle, the spindle sometimes being provided with a special core for gripping the interior of the paper cone. A base support against which to push the bottom of the paper cone may he provided at the foot of the spindle.

During the unwinding of the yarn from its paper cone, some troublesome dimculties are from the cone, the remaining yarn tends to sink.

toward the base of the cone and frequently to..- comes entangled. It may, for example, become tightened around the base of the cone, as well as catch underneath a portion of the yarn neat to the base of the cone. In any case, the previous orderly winding of the yarn on the cone is disturbed, and this in turn materially aflects the ease and rate at". which the yarn is being unwound to, for example, the knitting machine.

In the course of my investigations to solve this problem, I have discovered a construction for a yam base support that for the most part overcomes the dimculties just enumerated. The base of the paper cone as well as the base of the coned yarn, which are on difierent levels, may be appropriately supported so that in the unwinding of the yarn there is no tendency for the last lengths of yarn on the cone to sink to a lower level and thus become entangled at the base of the cone.

My invention accordingly contemplates a yarn support comprising a base member located at the foot of a spindle, the base member being provided with means for supporting the body of yarn independent of the protruding base of the paper cone which is on a diilerent level. in a present preferred practice of the invention the body of yarn rests on a piece of fabric stretched across the frame, the fabric being provided with an opening through which the lower protruding end of the paper cone may freely extend while the bottom oi the body of coned yarn rests against the fabric. The fabric support is sufficiently elastic and at a high enough level to accommodate cones of yarn having protruding base paper cone ends of varying lengths.

The various features oi the invention will be more clearly understood it reference is made to the accompanying drawings, taken in coniunc tion with the following description, in which:

Fig. l is a side elevation of an entire yarn support construction, showing a specific base support member illustrative of the invention in crcss-section; I

Fig. 2 is a section on the line 2 2 oi Fig. i;

Fig. 3 is an enlarged detail of the base sup port member of Fig. i; and

Fig. 4 is a perspective view of the various elements going into the base support, shown in their unassembled -forin.

The apparatus shown comprises a base sup port 10 mounted around a spindle 11 over which rests a paper cone 1?. wound with coned yarn it. These elements are in turn supported by a multiple adjustable bracket comprising a base link .14, two intermediate links 15 and i6, and a ballooning link 17 connected in series. The links are pivoted and movable at their adjacent ends, thumb screws l8, l9 and Zobeing provided, respectively, to tighten the links in any desired position. This bracket is disclosed and claimed in my copending applicationSerial No. name filed February 24, 1934. it will, however, be understood that so far as the present invention is concerned, adifierent bracket may be employed: In fact in some cases no bracket whatever is required.

Both intermediate links l5 and 16 are provided .with threaded holes 21 and 22, respectively, to

aflord a means of attachment. According to the construction shown, a pipe member 23 may be screwed into one of these holes at one end, and

' be attached at its other end to an ultimate supit comprises an extension member 28 fastened to the ballooning link by means of a screw 29. A lateral movable arm 30 is attached to the other end of the extension member by means of a screw 31, the arm being provided with a yarn guide 32, such as a porcelain eyelet, preferably smaller than the eyelet in the ballooning link. The eyelets 25 and 32 may be placed in co-axial alignment or they may be moved out of alignment to place the unwinding yarn under appropriate tension.

Referring now more particularly to Figs. 3 and d, it will be seen that the base support 10 consists of a pan-like frame 33 with a vertical side of adequate depth. An external lining of cork 34; is advantageously placed completely around the side wall. The frame is provided with a bottom 35 through the center of which extends a hole 36 sufiiciently large readily to accommodate the lower end of the spindle 11. From a considera-' tion of Fig. 3, as well as Fig. i, it will be seen that the frame may be fastened against the base link 14 by means of upper nut Lit-and lower nut 38 on the lower end of the spindle. It is desirable to depress a portion of the bottom of the frame surrounding the hole 36 to provide a protruding shoulder 39, so that a free space so is in turn provided between the bottom 35 and the top of the base link 14. l

An appropriate length of circular knit fabric li extends through the center-hole d2 of a washer-like pasteboard disk l3. 'The center hole is sumciently large to accommodate not only the spindle 11 but also the base end of the paper cone 12. The exterior diameter of the disk is suihciently small easily to fit into the interior of the frame 33. Referring to Fig. i, the tubular knit fabric ilis sufficiently long so that its lower end dd may be stretched completely over the frame 33 and downwardly over the cork lining 34. With the paper disk as in position as shown, the upper end 45 of the tubular knit'fabric is likewise stretched over the frame and downward ly across the cork lining '34.. An extensible band member i6 equipped with a coiled tension spring at fits over the frame member 33, and securely presses the double thickness of tubular knit fabric against the cork lining 34. The free ends of fabric are advantageously tucked into the free space so below the frame.

While any suitable spindle may be employedon which to mount the coned yarn, Fig. 3 likewise illustrates a core member 48 adapted to be screwed up and down the spindle. Adjustable cone gripping fingers 49 fit in longitudinal slots in the core, and are pivotally secured to the core by means of a circular coil spring 50 extending completely around the core. This practice is more particularly disclosed and claimed in mycopending application Serial No. 712,747, filed February 24, 1934.

From the foregoing discussion it will be seen that the tubular knitted fabric isstretched across the top of the frame 33, the washer-like paper disk 43 being suspended between the two layers of fabric. The layers of fabric may be drawn tightly across the frame, and thus provide a free space above the bottom of theframe which is adapted to receive the protruding base end of a paper cone mounted on the spindle. The taut fabric is at a sufflciently high level to meet the base of the body of coned yarn, as seen in Fig. 1. The pad support thus provided is sufliciently adjustable to accommodate itself to varying levels of coned yarn with respect to the foot of its paper cone.

Since the yarn itself rests on the taut fabric support, there is little opportunity for the unwinding yarn to become entangled. As indicated, the lower protruding end of the paper cone is protected so that the unwinding yarn cannot catch and tighten In this way the last lengths of yarn may be safely and readily unwound.
