YARN SUPPORT Filed Feb. 24, 19:54 2 Sheets-Sheet 2 INVENTOR CARL EPPS BY I - v AITORNEYJ yarn Patented May 14, 1935 UNITED STATES PATENT OFFICE ion Corporation,

a corporation of Delaware Application February 24, 1934, Serial No. 712,748 3 Claims.' (01. 242-130) This invention relates to yarn supports and has for its object certain improvements in the structure of yarn supports. The invention relates more particularly to improvements in adjustable multiple position brackets for supporting wound yarn.

In the manufacture of yarns from strands and the like the material is customarily wound on a cone, bobbin, cop or similar device. Cone winding, for .example, .is widely employed in the manufacture of artificial silk yarn. The yarn is wound on tapered or conical shaped pasteboard or paper tubes. The cones of yarn are subsequently unwound in the making of textile fabrics. In the manufacture of hosiery, for example, the coned is unwound directly to a knitting machine.

Special devices areemployed to unwind the yarn. The coned yarn must be appropriately supported in order that it may be conveniently and emciently unwound and passed to a knitting machine, or whatever device is employed to receive and fabricate the yarn. A number of difficulties are encountered. The devices employed to support the yarn may not be readily adaptable to the particular knitting machine employed. It

may be inconvenient to place a new cone of yarn,

for example, in position for unwinding. Also, the coned yarn may be unwound under non-uniform conditions of tension, which frequently results in the formation of knots or kinks in the moving yarn, and causes a lack of uniformity in the knitted fabric.

As a result of my investigations I have developed a yarn support that largely avoids the difliculties just mentioned. The support is readily adjustable to a great number of different positions that adapts it to be employed in conjunction with almost any type of knitting machine or other device to receive unwinding yarn. .Means are provided in association with the adjustable support for varying and controlling the tension under which yarn is unwound. 1

The improvement briefly contemplates at least a four-link adjustable position bracket, the first link in the series being a base adapted to support a spindle. At least one of the intermediate links is adapted to be securely fastened to an auxiliary support, such as a knitting machine. The last link is a ballooning link provided with a yarn guide. A tension device is preferably mounted on the ballooning link to steady the unwinding yarn. Means are present for tightening the links or joints to hold the bracket in fixed position.

These and other features of the invention will be more apparent on considering the attached drawings, taken in conjunction with the following description, in which:

Fig. 1 is a side elevation of an adjustable bracket of the invention, showing a cone of yarn mounted in a vertical position for unwinding upwardly; 5

Fig. 2 is a plan view of Fig. l; Figs. 3, 4'and 5 are side elevations of the adjustablebracket, showing cones of yarn mounted in various inclined positions for unwinding.

Fig. 6 is a side elevation of the tension device 10 in .one mode of application.

The adjustable multiple position bracket shown comprises a base link 10, two intermediate links H and I2 and a frame or ballooning link I3 connected in series. thumb screws l4, l5 and I6 are provided at the pivoted joints of the links, respectively.

The base link-is provided with a spindle i'l, attachable at or near the exterior end of the link by means of a threaded nut l8, which is adapted to receive a cone of yarn I! mounted on a tapered paper cone 20. Means are advantageously provided on the spindle for gripping the interior of the paper cone, to prevent it from turning and to hold it securely for the unwinding of the yarn. The cone gripping means employed may, for example, be of the improved type dis-. closed in my copending application Serial No. 712,747, filed February 24, 1934.

In order to.facilltate the unwinding of the yarn, the base link is also advantageously providedwith a frame or yarn supporting device 2|. This device may be cylindrical in contour, an elastic fabric yarn support 22 on which the yarn itself may rest being stretched at least in part across the same. The fabric is drawn taut around the perimeter of the supporting device, and is clamped to the side thereof by means of a ring member 23 made adjustable by means of a tension spring 24. A circular opening 25 is provided by 4 the fabric for the insertion both of the spindle l1 and the lower end of the paper cone 20 extending beyond the base of the coned yarn itself. This pad support may, for example, be of the type disclosed and claimed in my copending application Serial No. 712,746, filed February 24, 1934.

Both intermediate links II and I2 are provided with threaded holes 26 and '21, respectively, which are adapted to receive a complementary support member 28. This support member may in turn be secured to the ultimate support 29 for the entire bracket structure; for example, a knitting ma chine. Means other than threaded

holes

26 and 21 may of course be associated with the intermediate links H and I2 for fastening purposes.

Tightening means, such as 15,

' position, inclined upwardly, the unwinding yarn It will be clear from the construction shown that either or both of the intermediate links may be employed to support the entire bracket.

The ballooning link I3 is provided with a 'yarn guide 30 of conventional design, such as a porcelain eyelet. The ballooning link is also preferably provided with a tension device 3| of suitable construction. Figs. 1, 2 and 3 illustrate a tension device in combination with the bracket in accordance with the invention. It comprises an.

extension member 32 securable to the ballooning link by means of a screw 33 extending therethrough. The upper end of the extension member is provided with a. lateral arm 34 securable by means of a threaded screw 35. The lateral arm is in turn provided with a yarn guide 36; such as a porcelain eyelet, preferably smaller than the porcelain eyelet 30. It will be seen from the conruction illustrated that the porcelain eyelets an and 36 may be placed in co-axial alignment, or deviated from such an alignment to any extent desired simply by rotating the extension member 32 on the ballooning link l3; or by shifting the position of the lateral arm 34. In this manner any desired operating tension may be placed on yarn 31 as it is unwound from the cone l9 to, for example, the knitting machine. If reference is made to Fig. 2, it will be seen that the lateral link 34 has been movedsidewise so that the

porcelain guide eyes

30 and 36 are offcenter, which places the unwinding yarn under tension.

The yarn may be placed under additional tension by winding it around the member 32, as shown in Fig. 6, with the guide 36 in the position illustrated or in any other desired position with respect to the guide 30. p

The cone of yarn I9 shown in Fig. 1 is in a vertical position for unwinding. Inspection of Figs. 3, 4 and 5 shows the coned yarn in various inclined positions for unwinding. In the caseof Fig. 3, the coned yarn is supported in a lateral being passed through the tension device. Fig. 4 likewise shows the coned yarn in a lateral position. inclined upwardly. but the tension device is not employed. the unwinding yarn merely being assed through the porcelain eyelet 30' in the ballooning link l3. In the case of Fig. 5, the coned yarn is supported in a lateral and down wardly inclined position, the unwinding yarn being passed merely through the yarn guide in the ballooning link.

A comparison of Figs. 1. 3, 4 and 5 will show the adjustable bracket placed in various positions, both with respect to ultimate support as well as unwinding. In the case of Fig. 1 the bracket is supported through intermediate link I I to.an inclined support 29 adjacent the bracket. Fig. 3 shows the bracket supported through intermediate link H onto ultimate support 29 in a horizontal position below the bracket. Fig. 4 shows the bracket depending through intermediate link l2 to the ultimate support 29 above the bracket. In the case of Fig. 5, the bracket is supported through intermediate link .I 2 to ultimate support 29 placed below the bracket.

In operation the bracket is fastened at some convenient place on or in close proximity to the looning link, move it out of the way, and insert a new cone on the spindle; the base link thus always remaining rigidly locked to intermediate link II. The ballooning link is then returned to its operating position and fastened by means of thumb screw I6. After threading the guide porcelain eyelet 3|), the cone of yarn is ready for unwinding. In case use is to be made of the tension device 3|, the yarn is likewise threaded through porcelain eyelet 36. The unwinding yarn may then be placed under appropriate tension by moving the lateral arm 34. It will be seen that the device of the invention offers a number of desirable improvements in the operation of unwinding yarn.
