3 Claims. (Cl. 242-130) This invention relates to a novel holder for yarn packages, constructed to facilitate fast and easy creeling.

Yarn packages are commonly wound on hollow cones, tubes or cores, hereinafter called tubes, and these tubes are usually made of wood, paper or fiber. The common way to support these tubes so that the yarn or other strand can be drawn from the package in an axial direction is to mount the hollow tube on a projecting post It is imwinding yarn may exert on the package.

Various means have been provided heretofore upon such post or bracket for frictionally engaging the inner walls of the hollow tube, or for piercing such walls so as to hold the tube in place during the yarn unwinding operation. Since in a textile mill large numbers of yarn packages may be used, considerable work is involved in mounting the full packages on the supporting posts or brackets and removing the empty tubes therefrom. It is therefore important to so construct the supporting post or bracket and associated parts that creeling can be quickly and easily performed.

Having in mind the foregoing, the present invention contemplates a simple and inexpensive holder for yarn packages, which will operate when its axis is supported in a horizontal position, or vertical position or at any angle therebetween, and it is so constructed that when the tube is mounted on such holder in its operating position it will be retained in place, so that a strong pull upon the unwinding yarn will not be likely to pull the tube from its supported position.

This object is secured by providing a holder comprising a post adapted to be secured in a fixed position, and which is shaped to fit the bore of the yam-receiving tube, but is long enough to extend only a comparatively short distance within the tube. Furthermore this post has its base and an adjacent sidewall partly cut away to clear an end portion of the tube when the tube is tilted with respect to the post, and the opposite wall of the post from this cut away portion is made short enough to clear the edge of the tube when the latter is tilted with respect to such post. The purpose in forming the tube supporting post in the manner just described is to permit the tube to be placed over the post in tilted relation therewith, and then moved into axial alignment with the post as the tube is pressed onto the post, which is shaped to fit the bore of the tube.

In order firmly to secure the tube to such post so that the tube will not be dislodged by a strong pull upon the yarn as it is removed endwise from the package, the

post is provided, near saidcut away sidewall, with a 2,761,632 Patented Sept." 4, 19 6 ice severe pull upon the yarn package by the yarn as it is "disk" pad 11 adhesively secured to the upright.

delivered endwise from the package.

. The above and other features of the present invention will be further understood from the following description when read in connection with the accompanying drawing, wherein: Y

The single figure of the drawing is a side elevation with parts in section, the post being shown in side view while the package is shown in section in its operating position,

and in do't-and-dash lines inits tilted position.

The yarn package holder contemplated by the present invention may be used to support various types of packages of yarn cord or strand, and such packages may have either conical or cylindrical shaped tubes formed of lightweight tough'material such as paper or fiber that the pin, to be described, can pierce. Such holder maybe mounted so thatits axis extends in a horizontal direc particularly well when rigidly mounted in a horizontal 7 position as shown.

The yarn package holder, contemplated by the present invention, is shown asbolted to an upright 10 shown in side'view, and this upright preferably has a relatively wide flat face to provide a wide supporting base. for the This pad maybe formed of lambs wool the fibers of which serve gently to support the coils of yarn as they unwind from the larger end of the conical package 12. This package is shown as wound upon a conical tube 13 which is supported during the yarn unwinding operation by a short post 14, the base of which is clamped against a face of the upright 10 by the clamping bolt 15. The pad 11, it will be noted, is cut away at its center to provide a central hold that clears this post. The post 14, while relatively short, is conical in shape to fit the bore of the conical tube 13. This post, it will be seen, is cut away at its upper side where the base and upper sidewall meet as indicated by 16. The purpose of so cutting the post away is to provide a clearance space for an edge portion of the tube 13 when this tube is tilted to an incline position, as shown by dot-and-dash lines in the drawing. It will also be noted that the lower side of the post 14 is shorter than the upper side of such post. Such lower side is made relatively short so that it will clear the lower edge portion of the tube 13 when the tube is in the tilted position just mentioned. The upper wallxof the post 14 is long enough to provide ample support for the full package mounted upon the post.

The post has extending from its upper sidewall near the cut away portion 16 the protruding pin 17 which has a sharp point. This pin preferably is externally threaded like a screw and is introduced through the hole 18 to the portion thereof which is of smaller diameter, and is threaded to receive the threaded pin 17. As a result of this construction the amount the point of the pin protrudes from the post can be controlled by using a screw driver to turn the threaded pin.

It will be seen from the construction of the post 14 just described that when a yarn package is to be placed upon this post it can be easily tilted to the dot-and-dash position shown in the drawing, so that the upper edgeof the yarn package will sink into the soft pad 11 as shown. Then as the package is pushed towards the supporting upright 10 and is swung downwardly into 12 passes to a guide eye 19 of usual construction and supported some distance from the package but in axial alignment therewith as shown.

It will be seen from the foregoing that a holder for yarn packages, constructed in accordance with the present invention, is simple and inexpensive to construct and that it makes possible quick and easy mounting of a loaded package on the holder in the desired position for over-end delivery, and that when the cone is empty it canbe quickly and easily removed from the supporting post by merely tilting the tube upwardly, and then pulling it ofi the post 14.

@Having thus described my invention, what I claim and desire to protect by Letters Patent is:

1. A holder for a yarn package, comprising a short post that is rigidly supported and shaped to fit thebore of a yarn-receiving tube, said post having its base and an adjacent sidewall partly cut away-to clear an end portion of the tube when it isplaced over the post at an inclination thereto, and a pointed pin set in a sidewall of the post to project therefrom near said cut away portion of said base and sidewall, whereby the tube can be anchored to said post by slipping it over the post in tilted relation thereto and then moving it into axial alignment with the post so as to cause the pin to pierce the inner wall of the tube.

2. A holder for a yarn package, comprising a short post adapted to be rigidly mounted in a horizontal position to support a yarn package for over-end delivery and shaped to fit the bore of ayarn-receiving tube, said post having an upper and lower sidewall when mounted in a horizontal position, said post having its upper sidewall and adjacent base partly cut away to clear said tube 4 when it is placed in a tilted position over the post and said post having its lower wall short enough to clear the lower portion of the time when it is so tilted, and a pointed pin set in the upper sidewall of the post to project therefrom near said cut away portion and adapted to pierce the inner wall of said tube as the latter is moved to its operative position on said post.

3. A holder for a yarn package, comprising a short post that is rigidly supported and shaped to fit the bore of a yarn-receiving tube, a pointed pin set in a sidewall of the post to project therefrom, said post having a References Cited in the file of this patent UNITED STATES PATENTS 777,780 Easton Dec. 20, 1904 2,055,626 Howell Sept. 29, 1936 2,245,070 Cumfer June 10, 1941 2,461,724 Davidson Feb. 15, 1949 2,534,579 Dennis Dec. 19, 1950 FOREIGN PATENTS Great Britain Oct. 13, 1949
