HOLDER FOR YARN PACKAGES.

Application led February 11, 1922. Serial No. 535,950.

To all whom t may concern:

Be it known that I,4W1LLIAM D. HARTS- HoRNE, a citizen of the United States, residing at Methuen, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements vin Holders for Yarn Packages, of which the followin is a specification.

his invention is for use 'in the spinning, setting and weaving of yarn, more particularly of worsted or cotton yarn used for filling.

In the process of spinning of yarn for weaving purposes, whether it is to be used for warp or filling, it is necessa I to give it a certain amount of twist in or er to assure evenness, roundness and strength. The amount of twist required depends largely upon the quality or character of the cloth o which the yarn is toh become a part. In order to hold the fibres in their position and retain this twist, it is necessary to subject the yarnto some setting process which consists of introducing a proper amount of moisture, either hot or cold.

To accomplish this, the yarn on bobbins was formerly stored away and kept in a cool damp room, usually in a cellar, for a long period or until it had lost its tendency to kink or loo and had absorbed the re uired amount o moisture. This plan, alt ough effective was, nevertheless, slow and expensive because it kept tied up in the process a large amount of yarn and a great many bobbins.

The general practice at the present time consists of thoroughly steaming the yarn by allowing it to remain in or to pass through rooms or chests filled with hot steam or vapor which gives it the required moisture v and accomplishes the desired setting effect in a relatively short time.

As is to be expected, however, it is found that these conditions of heat and moisture to which the yarn is subjected have a damaging effect on paper tubes or wooden bobbins on which the yarn is wound, whether originally spun thereon or subsequently wound by some so-called quilling operation. The paper tubes are made practically worthless for further use, while the wooden bobbins are softened and swelled, or twisted out of shape, and their life is materially shortened. Further than this, the tubes or bobbins in general use are solid, and for this reason the moisture has to penetrate the lentire mass of yarn from the outside.

I am aware that perforated metal cops and bobbins have been used for dyeing and for other purposes, and I do not claim broadly the idea of such a perforated metal cop or bobbin. I do claim, however, to be the first to provide a light, inexpensive barrel or tube, preferably, rolled from perforated sheet metal, having a member by which it can be firmly attached to and detached from a suitable head for the purpose of making it available for use in a loom shuttle.

The principal feature of my present idea is the provision in a holder for a yarn package of a barrel preferably of moistureresisting metal upon which, without its head, the yarn can be spun or twisted and which can then, with others of a similar kind, be treated in a steam chest or box or any suitable steamin or boiling arran ement to set the yarn, in combination with a readily attachable and detachable head to be thereafter attached, for weaving or other purposes.

As it is necessary that this barrel should be capable of being held on a spindle or other device in a spinning or twisting frame, I prefer to make it of more or less elastic sheet metal so rolled up as to leave a longitudinal split. This allows enough spring to hold the barrel im place. Besldes this, not only to permit the steam to get inside the yarn package but to prei vent theyarn from slipping, I perforate it with a plurality of holes.

Various types of catches between the barrel and the head can be used, but it is desirable that the whole structure should be light in weight and should have no projecting parts which might catch the yarn or injure the operators hands.

I claim to be the first to conceive the idea of a straight barrel of perforated metal or other suitable material without a head to be used in the process of spinning, twisting, or quilling and steaming, combined with a head which may be attached only before, during, and after the time when the bobbin is being used for weaving filling in a loom or other particular process.

I claim the use of a metal barrel with a head which may be of wood or any material which is readily attachable to and detachable from the barrel,

l also claim to be the first to provide a barrel with a member by which it can be attached to and detached from a head.

Figs. 15, 16 and 17 are other elevations partly in section showing still other modifications.

lf show my preferred type of yarn holder in Figs. 1, 2, 3, 4, 5, 8, 9. The barrel B is formedof a sheet of metal, preferably, such as duralumin, which is not affected by steam or boiling water and will not stain the yarn. Such sheet is perforated with the holes 31 and may have the bead 13 proximate what is to be its tip expanded therefrom, and the bead 15 expanded therefrom near what is to be its base, either before or after it is rolled up into a tube or barrel with its opposite edges 10, 1() substantially brought together. Preferably, a flat sheet of metal is punched with the holes 31 and at the same time the beads 13 and 15 are expressed, after which it is rolled up on a mandrel with its edges touching.

Beads 13 and 15 may be expanded before or after rolling. Bead 13 is proximate the tip and serves to guide the yarn from the yarn package, such as L, smoothly over the tip 12. rFhis tip 12 is likely to become more or less roughened in the rough usage of the factory, but bead 13 keeps the yarn away therefrom and also protects the hands of the operator.

The bead 15 is a sufficient distance away from the base 14 of the barrel so that when assembled with the head it will form therewith one of two firm holding lines of contact, from without or within the barrel.

After the barrel B is made, it may for the purpose of spinning be placed upon a steel spindle for ring spinning or twisting or forced over the wooden shank 8 of a wooden bobbin M carried by the tube and whirl 7 in the case of cap spinning or twisting. rlhe barrels split formation allows it to be forced over bobbin M or over a guide button on the steel spindle whereby it is held firmly in position during. the spinning or twisting.

'llhe yarn 6 is spun or twisted thereon forming the yarn package L which may either be what is known as a warp wind or a simple cop like filling wind.

1n Fig. 2, lf show this yarn package, including barrel B and yarn L, removed from the spinning frame and placed in a steam chest or other moistening device, which may be even a damp cellar. The arrows indicate how the moisture or steam passes in through the holes 31 to the inside of the package.

Figs. 3, 4 and 5 show details of the preferred form of head H. rllhis may be made of sheet metal, which may be of moisture resisting material or otherwise, as ordinarily this head does not come in contact with hot steam. 1t is formed with a round base 20 through which is, preferably, a passage 2l for a spindle in case it is desired to usethis in a shuttle having a spindle. necessary, however, in a shuttle for an automatic loom which has jaws, such as those shown at N in Fig. 9, with grooves 27..

For this type of shuttle, l prefer to use elastic clamp members 22, 22, 22, 22, separated by spaces 24, 24, 24, 24, each having expanded therefrom the three beads 23, 23. 23 adapted to engage grooves 27, 27, 27- of the jaws N.

Preferably, the upper edge of each clamp 22 at 25 is rolled over in position so that it will permit bead 15 of barrel B to just pass inside and will engage it firmly.

'll'he base bead 15serves as an attaching member for the barrel, and the clamp members 22, 22, 22, 22 serve as elastic attaching means for the head, cooperating therewith. The distance from barrel base 14 to base bead 15 should be such that when base 14 rests on head base 20, the rolled-over edges 25 of clamps 22, 22 pressing against the outer edge of bead 15 will hold bases 14 and 2O firmly together.

1s the head H need not be used in spinning nor in setting, it can be attached to the barrel by unskilled labor just before beingput in the magazine of the loom, and after it is forced into the shuttle between the jaws N these jaws force the clamp members 22 against the barrel and against bead 15 so that Utl rFhis is not the two parts are irmlyand elastically held in position with no danger of rattling out during Weaving.

In Figs. 6, 7 and 14, I show a barrel A which is split at- 30, perforated at 31,- has the tip 32 and bead 33 proximate thereto, but at the other end has a series of wings 35 adapted to engage the interior threads 42 on a solid head C. This head C has an end throu h which there may be-a spindle hole 41 and t e exterior steel rlngs 43, 43, 43 for use in an vautomatic loom. The pad P is shown between an end of the barrel and the interior of the head to prevent rattling and to hold the parts irmly in position. The split construction of the barrel also helps in this respect.

Pad P may be of washer form with a hole corresponding to 41, preferably of more or less elastic material such as felt or rubber and of a thickness so that when the barrel A is in position the parts will all be firmly held together. A pad such as P can be used with the type of barrel B and head H if necessary, but ordinarily the elasticity of the l clamps is suiicient.

In Figs. 11 and 12, I show still another modification. in which the barrel G is per- Jorated at 61 but is not made of sheet metal and is not split, while the bead 63 is at the tip 62 instead of a short distance therefrom. There may be another bead 65 to prevent the yarn slipping down, but this is not necessary 1n all cases.

The head F is shown as having a spindle hole 51 and interior threads 52 which engage exterior threads 66 on the barrel. The pad P is omitted in the drawing but can be used.

In Fig. 14, I show a barrel A similar` to that shown in Figs. 6 and 7, which is perforated and split and has a bead 33 near the l tip together with wings 35 near the other end, in combination with a head T.

Head T is shown as made of solid metal with an outer end 70 through which is a hole 76 and about which are themetal rings 73, 73, 73 to fit in the jaws of the shuttle. On the inside, it is threaded at 72 to engage the wings 35 on barrel A. It also has a guiding and supporting tube 74 which is fixed in the hole 76 and extends u to a point inside barrel A, its end bein en arged at 75 to form an annular support or the interior of the bar- A pad P is shown outside tube 74 resting upon the barrel recess in head T between the end of barrel A and the end of head T. This pad forms part of the elastic attaching means including threads 72 and vwings 35 between the barrel and head.

While I prefer the various types hereinbefore described, I may use a compound bobbin, such as shown in Fig. 15, in which the barrel R is neither perforated nor split-and is not made of sheet metal but is madeof heavier stock which can be rounded at the tip 66 instead of having a bead thereat. I do not conne myself to the use of a metal barrel, however.

This barrel R of tubular form made of moisture-resisting material is shown as combined with a head S tmade of wood or similar material having a butt 67 and a shank 68 which is slightly tapered so that the barrel R can be driven on to it and will be thereby held in place. In this case, the attaching member of the barrel may be regarded as the inner bore 69, and the attaching means from the head cooperating therewith as the shank 68.

In Fig. 16, I-show a barrel B and a head H similar to those shown in Fig. 8, and instead of a washer such as P which goes under the end 14 of barrel B, I show a washer V, which may be of any material, set in on the bottom 20 of head H in such position that the end 14 of barrel B will slip inside of it thereby assisting the rim 25 to hold the parts more firmly together.

In Fig'. 17, I show a similar barrel B and a head 'I similar in all respects to I-I except that instead of the washer B I press inward an annular bead 70 in such position as to engage the end 14 of barrel B and to hold it rigidly in position together with rim 25.

I claim: l

The combination in a holder for a yarn package of a barrel of tubular form made of moisture resisting sheet metal split long-itudinally and having perforations, together with an expanded annular bead proximate its tip and an expanded annular bead near its base; with a head having an end which' engages the base of the barrel and elastic clamp members extending therefrom, each having a rim extending over said annular base bead, and expressed annular beads for engagement with the jaws of a shuttle.
