BALLOON RETAINING DEVICE Filed July 18, 1960 INVENTOR. DON E. FISHER ATTORN United States Patent 3,076,304 BALLOON RETAINING DEVICE Don E. Fisher, Pensacola, Fla., assignor, by mesne assignments, to Monsanto Chemical Company, a corporation of Delaware Filed July 18, 1960, Ser. No. 43,439 3 Claims. (Cl. 57106) This invention relates to balloon retaining devices and more particularly to rings for retaining thread balloons in spinning operations.

One of the disadvantages of balloon retaining rings used in the past has been that the thread balloon sometimes extends longitudinally outward past the ring. This causes the loop or balloon to snag on machine parts or to become tangled on itself. With this problem in mind, one of the objects of this invention is to provide a novel and improved device for retaining a thread balloon.

Another object of this invention is to provide a balloon retaining ring wherein the thread balloon is prevented from extending longitudinally past the ring.

Still another object of this invention is to provide a device for retaining a yarn balloon in a creel can.

A further object of this invention is to provide a balloon retaining ring mounted on a creel can in such a manner that the yarn balloon is free to move between the ring and the creel can until the balloon is shortened and the excess yarn is drawn out of the space between the ring and the can.

One of the embodiments of this invention contemplates a balloon retaining device wherein a ring is secured inside a creel can by a plurality of fingers which extend longitudinally out of the can and then radially outward to the can in such a manner that there is a spacebetween the ring and the can through which the yarn balloon is free to slide. This construction retains the yarn balloon inside the can until it is shortened.

Other objects and advantages of the invention will become apparent when the following detailed description is read in conjunction with the appended drawing, in which:

FIGURE 1 is a cross-sectional view of a creel can showing the manner in which the balloon retaining ring is mounted on the can, and

FIGURE 2 is a front view of the structure shown in FIGURE 1.

Referring now in detail to the drawing, there is shown a creel can 11 having a center post 12 upon which is mounted a package 13 of yarn which is to be withdrawn from the package. The yarn 14 is withdrawn from the package 13 through a guide 15 in a well-known manner.

A balloon retaining ring 16 has secured thereto a plurality of resilient or flexible fingers 17, the curved ends of which snap over the rim of the can 11 for holding the ring in the can. The fingers 17 extend from the rim of the can radially inward and then extend longitudinally Patented Feb. 5., 1963 into the can in such a manner that the ring 16 is held concentric within the can at a distance from the rim of the can. The positioning of the ring 16 in the can 11 provides a space 18 between the ring and the can into which the yarn may balloon as shown at 19. This holds the balloon within the can to prevent snagging.

In operation of the device, the yarn package 13 is placed on the post 12 and the yarn 14 is withdrawn through the guide 15 in a well-known manner. As the yarn balloons, the balloon will extend into the space 18 between the ring 16 and the can 11 and slide around this space until the excess length of yarn is taken up. This retains the balloon inside the can 11.

It is to be understood that the embodiment of the invention disclosed herein may be modified and that many other embodiments may be contemplated which will fall within the spirit and scope of the invention.

What is claimed is:

1. A device for retaining a yarn balloon in a creel can, comprising a ring adapted to be positioned in said creel can, and a plurality of elements attached to the ring and extending longitudinally therefrom parallel to and spaced from the sides of the can, said elements having curved ends extending radially and adapted to be secured to said can to support said elements and said ring, said elements being parallel to and spaced from the side of the can to provide a space for the yarn balloon.

2. A device for retaining a yarn balloon in a creel or can, comprising a balloon retaining ring adapted to be positioned in the can, and a plurality of elements attached to the ring and extending longitudinally therefrom parallel to and spaced from the sides of the can, said elements having curved flexible ends extending radially and adapted to snap over the rim of the can for supporting the ring, said elements being parallel to and spaced from the sides of the can to provide a space for the yarn balloon.

3. A device for retaining a yarn balloon in a creel can, comprising a balloon retaining ring adapted to be positioned in the can, and a plurality of flexible elements secured to the ring and extending parallel to and spaced from the side of the can, said elements having radially extending portions which are curved at the ends thereof for snapping over the rim of the can to hold the ring therein, said elements being parallel to and spaced from the sides of the can to provide a space for the yarn bfll') loon.
