This invention relates to a new and improved bobbin.

In the manufacture of thread such as silli, cotton, rayon, etc. and at subsequent times 1t 6 is usual for-convenience in handling, storing, knitting, etc. to wind the thread upon a bobbin from which it is thereafter unwound or rewound into skeins or other forms for future processing and repeated winding and rewinding of the thread, is not only undesirable from the standpoint of breaking or injuring the thread, but it is also expensive, and the main object of this invention is the provision of a bobbin of such form and construction that thread can be efficiently and uniformly processed upon the bobbin itself for any purpose such as washing, de-sulphurizlng, bleaching, 1 etc.

Other objects and advantages relate to the details of construction of the bobbin and the form and disposition of parts thereof, all as will more fully appear from the following description taken in connection with the accompanying drawings, in which:

Figure 1 is a perspective'view of the preferred form of my device.

Figure 2 is a section on line 2 -2 of Figure 1.

Figure 3 is a section similar to Figure 2 of a modified form of bobbin with a plug in the end thereof.

Figure 4 is a section on. line 4-4, Figure 1. Figure 5 is a view partially broken away of a modified form of the invention. 5 Figure 6 is a section on line 6-6, Figure 5. igure 7 is a section on line 77, Figure 6. The bobbin 1, as shown, is cylindrical in shape although certain objects of the invention may be obtained with variously shaped bobbins. Further, as shown in Figures 1 and 2, the bobbin may be formed with a closed end --2-, although that is not essential, as the bobbin may be open at both ends and during p1 ocessing of thread thereon, one end of the bobbin may be closed by a removable plug 14. As shown in Figure 3, the bobbin may be formed of any suitable material, but at present I prefer one made of fibre.

The wall of the bobbin 1 is formed, as

shown, with a plurality of perforations 4 in circumferential s aced relation and also spaced, as shown, f i'om the end 2 of the bobbin. Another plurality or row of perforations 5 is provided in the bobbin in circumferential spaced relation and spaced from the end 3 of the bobbin substantially as shown. The intermediate portion of the wall of the bobbin between the rows, 4. and 5, of perforations is provided with a multiplicity of uniformly spaced perforations. These perforations 6 may, as shown, be arranged in rows extending around the bobbin, or may be staggered, or otherwise arranged so long as they are substantially uniformly spaced to provide uniform capacity for transmission of fluid from the interior of the bobbin to yarn or thread wound thereon.

The usual method of winding thread upon a bobbin involves a traversing movement of the thread guide combined with a relative longitudinal movement of either the thread guide or the article or bobbin upon which the thread is to be wound, with the result that the material or thread wound on the central portion of the bobbin is of substantially uniform desired depth and tapers off at opposite ends of the central, unlformly thick, portion toward the opposite ends of the bobbin, as for instance, illustrated in dotted lines in Fig. 2. It will be apparent that if thread so wound upon a bobbin is to be treated by fluid passing through the perforations in the bobbin that a gradually decreasing quantity of such fluid is required to effect treatment of the thread at the o positely tapered end portions of the b0 y of the thread wound upon the bobbin. For

that reason, the opposite end portions of the bobbin including a space underlying at least a considerable portion of the tapered ends of the cop of thread are unperforated and in order to supply the desired quantity of fluid to the overlying portion of the thread or yarn, these opposite end portions of the bobbin are provided with a plurality of grooves 7 leading from perforations in the opposite end rows 4 and 5 and extendin toward the ends 2 and 3 respectively, suc

grooves-or channels gradually diminishing in depth as they approach the ends 2 and 3 respectively until they become flush with and blend into the outside surface of the bobbin at the points where the layer of yarn or thread upon the bobbin terminates. In this manner, fluid is distributed in gradually decreasing amounts to the opposite tapered end portions of the body of thread or cop wound upon the bobbin, in other words, the amount of fluid supplied to the intermediate, uniformly thick, portion of the cop is greater than the amount supplied to the trated in Figure 3, this permanently closed wall may be omitted and the bobbin may be formed with both ends open, but adapted to be closed in any suitable manner during processing as by a movable plug 14.

Although it is not essential, under some conditions, it may be desirable to connect series of openings or perforations through the bobbin wall. I have illustrated in Figure 1 two such channels 13 extending lengthwise of the bobbin and connecting a multiplicity of perforations to assist in uniform distribution of fluid. These channels, however, may extend either circumferentially or longitudinally, or in both or other directions with respect to the bobbin.

In Figs. 5, 6 and 7 a modified form of struc-' ture is illustrated, but which by reason of its formation is adapted for the supply of substantially uniform quantities of treating fluid to thread wound upon the bobbin, as

for instance in the form shown in Figure 2. This modified form of the invention includes theend rows of perforations 4 and. -5 respectively and the multiplicity of intermediate perforations 6-, but instead of the grooves or channels -7- the opposite end portions of the bobbin are formed with ribs 20 which taper outwardly toward the opposite ends of the bobbin from a pointadj acent the opposite end rows of perforatlons 4:- and --5 respectively, i. e. at the end rows of perforations the ribs are of a height suflicient to space the yarn wound thereon a short distance from the periphery of the bobbin, and from that point the ribs gradually decrease in height until they merge into the surface of the bobbin at substantially the point where thewound yarn terminates so that the spacing of the yarn from the bobbin gradually decreases in extent as the layer of yarn wound upon the bobbin gradually decreases in thickness.

Except as to the substitution of ribs -20 for channels 7 the construction shown in the several figures is the same.

It will be understood that the size, number and position of the perforationsin the central portion of bobbin, 1 may bevaried, depending upon the thicknessof the cop and the material of which it is formed. This is also true of the grooves 7 and -8. 01'.

the ribs 20 which may be varied in mun: her, size and depth, depending upon the thickness and character of the material to which fluid is to be supplied.

It will also be understood that the size and shape of the bobbin itself may be varied, as may be the material of which it is made, for although I have shown and described a specific structure and form of parts, as an exemplification or embodiment of my invention, I do not desire to restrict myself to the exact size, shape or relation of parts thereof, as various changes may be made within the scope of the appended claims.

I claim:

1. In a device of the class described, a hollow body having a plurality of perforations in the periphery of the central portion thereof and a plurality of grooves in each end portion of the body, each groove extending from a point adjacent an end of the body towards and into communication with a perforation and gradually increasing in depth as it approaches such perforation.

2. In a device of the class described, a hollow body having a plurality of perforations in the body in spaced relation extending circumferentially and longitudinally of the central portion and having .a' plurality of grooves extending from certain of said perforations towards one end of the body and having a plurality of grooves extending from certain others of the said perforations towards the other end of the body, said grooves gradually decreasing in depth as they approach an end of the body.

3. In a device of the class described, a hollow body having a plurality of apertures in the periphery of the central portionthereof and having a plurality of grooves connecting adjacent perforations and a plurality of grooves in each end portion of the body, each groove extending from a point adjacent an end of the body towards and into communication with a' perforation and gradually increasing in depth as it approaches such perforation.

4. In a device of the class described, a bobbin body having a plurality of apertures in the periphery of the central portion thereof, and a plurality of grooves in each end portion thereof, each groove extending from a point adjacent an end of the body toward and into communication with a perforation and gradually increasing in cross-sectional area as it approaches such perforation.

5. In a bobbin adapted to have wound thereon thread in a layer of non-uniform thickness, a hollow body adapted to receive a treating fluid therein, said bod having means for 5 conveying treating fluid rom the interior of the body to the outside surface thereof in varying quantities including grooves varying in capacity from end to end, such quantitles being proportional to the thickness of the layer of thread at the point of supply thereof.

In witness whereof I' have hereunto set my hand this 7th day of December, 1928..
