-9 Claims.

This invention relates to means for stripping unused rovings from skewers such as used in spinning frames and indisintegrating the rovings into a mass 01' disconnected fibers so that such fibers can be immediately transferred to the picking room and passed through the pickers along with other fibers coming from the opening room.

It is a well-known fact that in spinning rooms,

that when nearly all of the roving has been withdrawn from the tube disposed on the skewers in the spinning frame, that these are cast aside, and it is necessary to remove these unused rovings from the tubes before the tubes can be used again. Furthermore, it is desired to recover the fibers i'rom these unused portions, and heretofore the practice has been to pass a sharp knife longitudinally of the tubes to sever the various convolutions oi! rovings to quickly remove them from the tubes. This has resulted not only in injury to the tubes, but also in a shortening of the fibers because long fibers are cut in this operation, and when the cut fibers are passed back to the opening room and the rovings reprocessed to pass them through a picker to prepare webs of fibers, there is much loss on account of the short fibers being lost during the processing operation.

It is an object of the present invention to provide means for withdrawing the unused portions of rovings from the tubes on skewers and the like and disintegrating the fibers as they are withdrawn and thus preserving the fibers in their original staple length without any injury whatever to the same. Some of the objects of the invention having been stated, other objects will appear as the description proceeds, when taken in connection with the accompanying drawings, in which 2 container has screens l3 and H at each end thereof, and has a preferably circular opening l5 over which a suitable lid, not shown, may be placed and over which a bag can be placed for receiving the fibers within the box or container Ill. The container Ill has a lid i6 hingedly secured as at I! to one of the side walls of the box Ill. The lid l6 has a tubular member in penetrating the central top portion thereof near one end and has a plurality 01 supporting stands 22 and 23 in which is mounted a pipe 24 having a cut-off valve 25 therein and the pipe 24 is adapted to be secured by means of a clamp 26 to a flexible air hose 2! connected to a suitable source of compressed air, not-shown. The pipe 24 has a downwardly projecting restricted elbow 3.0 on its free end which projects down into the tubular member 23.

Figure 1 is a top plan view of the apparatus I with a portion broken away;

Figure 2 is a side elevation looking from the lower side of Figure 1 with portions broken away;

Figure 3 is an end view looking from the righthand side 01' Figures 1 and 2;

Figure 4 is a vertical sectional view taken along the line 4-4 in Figure 3;

Figure 5'is a view similar to the right-hand end of Figure 2, but showing a modified form of the invention Figure 6 is an enlarged sectional along the line 6-8 in Figure 2;

Figure 7 is an enlarged vertical sectional view of the top center portion of Figure 2.

Referring more specifically to the drawings, the numeral ill indicates a container, preferably of rectangular shape and having wheels I I. The

plan view taken Mounted in the top of lid portion It: and near' one end thereof is a plurality of spaced porcelain supports 33, each adapted to receive the lower pointed end 34 of a skewer 35. c The skewers 35 are vertically arranged and the upper ends of these skewers are restricted as at 36 and these restricted portions are adapted to penetrate suitable holes 31 in a horizontally disposed board 38 which is supported near each end thereof by means of vertical supports 40 and 4|. These skewers each have a tube 43 fitted thereon, and

said tubes 43 before being fitted or slipped onto the skewers 35 have wound thereon a plurality of Y convolutions of rovings 44. These rovings are wound onto a cross-sectional diameter of several inches and these rovings are led from the skewers and tubes through a spinning frame apparatus.

When nearly all of the rovings are exhausted from a skewer or tube thereon, the same is removed. In the present embodiment of this invention, these skewers 35 with the tubes 43 thereon are arranged in the plurality of supports 3.3 as shown in the drawings, and one at a time, an end is withdrawn from the skewers and is passed down around the restricted tube 3| where a blast Y of compressed air not only withdraws the roving 44 from the tube 43 but also disintegrates the flbersof the roving and converts these fibers into a fiuffy mass. When it is desired to remove the fibers from the container in, the lid Hi may be raised upwardly and the operator may guide the fibers out through the opening I5 into a bag secured around the annular rim l5.

Or if desired, instead of letting the disintegrated rovings fall into the container l0, there may be provided an arcuate tube 50 which will be secured to the lower surface of the lid I8 and surround the tube 20, and. the rovings as they are withdrawn from the tubes 43 will be disintegrated by the let of air and will be iorced loosely by the blasts of air along tube I and out the lower end thereof where a suitable bag can be disposed over the right-hand end of the tube 50 in Figure 5, or if desired. a suitable pipe can be connected to this tube 00, and the fibers can be carried by suction or otherwise to any desired art of the mill such as the opening room or the icker room where they will be reprocessed.

The rate of feed of the roving N from a skewer 48 is regulatedby the sharpness of the pointed lower end or the skewer. If the roving ieeds too fast, the lower pointed end of the skewer can be flattened to thus cause the skewer to present more friction or drag to its rotation. I

The suction of air around the compressed air nozzle 30 does not take any appreciable twist out of the roving, but when the roving comes in contact with the blast of air from the nozzle, the roving is disintegrated.

The jet of compressed air from the nozzle 30 creates inwardly moving air currents around the nozzle and serves to feed the roving past the nozzle 30.

ployed, they are used in a generic and descriptive sense only, and not for purposes of limitation, the scope of the invention being defined 'in the claims. a

I claim:

1. Apparatus for stripping an unused roving from a skewer and disintegrating the fibers, comprising apparatus for holding for rotation a plurality of skewers each having a roving thereon, a tube through which the end of a roving is led, a pipe having an open end extending into the tube and having its other end connected to a uitable source of compressed air, whereby the stream of compressed air passing through the tube will unwind the roving from the skewer and disintegrate the same.

2. Apparatus for removing unused rovings from a yarn package comprising a container, means for rotatably supporting a plurality of yarn packages on the container, said container having a tube penetrating the cover of the same, a pipe for conducting compressed air and having an open end extending into the tube, the free end of a roving from a package being adapted to be insex-ted into the tube beside the nozzle, and the compressed air issuing from the nozzle serving-to unwind the roving from the package and to dis-' integrate the fibersthereof and to project them into the container.
