This invention relates to textile spools and more particularly to those known as warping spools for use in feeding yarn strands onto beam-cylinder or ball warps preparatory to weaving fabrics. It aims to provide spools of a construction adapted to special loading and arrangement for feeding yarn according to the novel method of high-speed warping set forth in my U. S. Patent No. 1,639,927 dated August 23, 1927, for method and means for high-speed warping.

The invention will be best understood upon further description with reference to the accompanying drawings wherein embodiments filthereof are illustrated in loading and-in feeding positions.

In said drawings: Fig. 1 is an elevation of one form of spool embodying the invention represented on a winding-spindle for loading;

Fig. 2 is an end elevation of said spool, showing the manner of securing the end of an innermost winding of yarn to the outside thereof;

Fig. 3 is a view representing a pair of the spools as arranged on a creel-rack for uninterrupted feed of yarn according to a special method of high-speed warping;

Fig. 4 is an elevation'of a modified form of spool likewise represented on a windingspindlefor loading, the said spindle being shown partly in section;

Fig. 5 is an end elevation of the modified form of spool showing the manner of similarly-securing the end ofan innermost winding of yarn to the outside thereof; and

Fig. 6 is an elevation showing a detail of the modified spool construction.

In the illustrative embodiments, spools of conventional type are shown respectively comprising a hollow or axially bored barrel 5 having fiat disc-like heads 6 secured on opposite ends thereof. This barrel is usually made of wood, while the heads are preferably formed from hard vulcanized-fibre or other composition resisting breakage under rough usage conditions. These heads are rigidly secured to'the barrel ends by centrally bored wooden plugs or bushings 7 driven thereinto through central frusto-conical and notched or ribbed openings in the heads, said plugs being formedwith enlarged tapering headportions resultantly compressed within said apertures in the heads and with reduced gluecoated shank-portions fitting into the bore or receptive counter-recesses formed in the barrel ends.

The head on one end of the barrel in both forms of spool is shown cut through on a substantially radial line to provide a narrow slot-opening 8 in this instance extending from the periphery of the barrel to the periphery of the head. The edges of the head along the out are advantageously beveled or rounded smoothly as indicated, so as to obviate possibility of cutting the yarn or thread wound onto the spool. In some cases obviously this opening through the head might extend only partially toward the heads periphery or in other words may be formed as a part-length slot or elongate hole instead of the full-length slot shown, but it should always exten inwardly to a point where the inner face of the head contacts with the barrel. 7

In the form of spool illustrated in Figs. 1 and 2, the plu or bushing 7 at the end holding the slotte head to the barrel is left projecting somewhat beyond the outer face of said head, while the plug at the other end is trimmed ofl' substantially flush with the head at that end. The projecting plug in effect providing an axial extension of the spool barrel is lathed or trimmed to bottle-neck form to provide a groove 7* therein contiguous to the outer face of the head. Said plug is also axially counter-bored to a depth substantially level with the outer face of the head so as to give its projection the form of a ring. In this projection, narrow slits 7 are shown cut on lines of chords thereacross to a de th preferably less than that of the counterore.

Spools of this construction may be loaded and used for general purposes like any ordinary s 001, but are specially adapted to unusual loading and arrangement for magazine or continuous feed 0 yarn in high-speed warping operations according to. the novel method hereinbeforementioned, wherein the yarn is drawn oif the ends of the spools or m loo the spool is placed on the spindle with its slot-- ted head up but this particular form of spool may be applied with either end or head resting on the spindle cup.

A traveller-guide represented by the eye leted member 11 is shown in the upper position of its movement up-and-down or backand-forth in parallel relation to said spindle (or to the barrel of the spool thereon) for evenly guiding a thread a or strand of yarn onto the spool barrel during rotation with the spindle, From a supply bobbin (not shown), a strand of yarn 12 is shown passingthrough said traveller-guide to and partly around the spool barrel, thence through the slot 8 to the outside face of the spool head and then several times around the projecting plug 7 within the groove 7 where its end is finally engaged in one or more of the slits 7 in said plug (see Figs. 1 and, 2). In thus fastening the end of the yarn, it is advantageously extended across the plug as shown in Fig. 2 so that it may be grasped more easily when .desired to disengage or loosen it after the spool is loaded.

As thus extended through and fastened at the outside of one of the spool heads, the end of the yarn is kept from flying around and is also shielded while the spool is rotated for loading through the traveller-guide, and when the spool has been fully loaded by the yarn windings thereon, the trailing end of its innermost winding will be left extending outwardly from the loaded barrel for connection with the strand on another spool after first loosening to hang free.

In Fig. 3, a pair of the spools loaded as described are represented on a creel-rack in arrangement for magazine or continuous feed of the yarn in higheed warping operations wherein the yarn is drawn off the ends of the spools according to the method described and claimed in my aforesaid Patent No. 1,639,927 dated August 23, 1927. In said figure, the spools (with projecting plug down) 5 own engaged'over axis-pins 13 inclined to a common take-off eyelet 14 equi spaced fromthe spool ends, through whichvthe feeding yarn strand is passed to and through a tensioning-device 15 between guide-eyelets 16 and from there to the back comb-member of i a warper machine (not shown).

In this arrangement, the trailing end of the yarn on the feeding spool is shownconnected to the leading endof the yarnon the other or next supply spool, while-the trailingend of of the yarn-on the latter is s'ho'wnhanging for like connection ;with the. leading end of the are yarn on still another spool to replace the first one. As soon as the yarn on the feeding spool is exhausted, the feed is uninterrupted ly transferred to the other spool, and the emptied spool is then replacedby another loaded s pool which is similarly connected to the continuing feed spool. A plurahty of the spools may be arranged and successively connected in this manner, so that a continuous and uninterrupted supply of yarn will be assured during the entire warping operation.

The described magazine feed arrangement of the spools is possible only when the innermost or trailing ends of the yarn thereon extend outwardly for free connection with the leading end of yarn on other spools, but it' is not customary to .load spools in this manner. Moreover, the ordinary warping spools are not adapted for loading in this way, and if attempt to do so were made, the necessarily loose end of the yarn would simply slip off the barrel with rotating pull or fly wild until it became entangled with the am feeding onto the spool, which would 02 course result in I breakage of the yarn.

The invention therefore provides a special kind or form of spool ermitting the innermost end of yarn 10a ed thereon to be extended and fastened to an outside part for holding it taut and shielded from the winder mechanism during the loading operation and leavin after t e spool is loaded. Such spools have this particular and important advantage over the ordinary warping spools for the stated'purpose, and the added advantage that they will not easily break nor cause injury to the hands in common usage, so that the invention supplies a distinct need in the art.

In the modified form of spool illustrated in Figs. 4 and 5, the plugs 7 at both ends are trimmed ofi substantially flush with the heads, and in lace of the projecting plug of the spool first escribed, two slip-catches 9 are fixed on the outside face of the slotted head. These catches are in this instance provided by it accessible like the outermost end,

small 'metal washers held close against the ever, it is advisable to .apply them to-the winding-spindles with 7 their slotted heads down or resting on the spindle cups to preventpossible injury to the hand in rasping to remove from the spindle while still rotatmg. v

The manner of loading the modified form of spool is illustrated in Fig. 4 wherein the slotted head is shown resting on the spindle cup with the slip-catches 9 encompassed by slip-catches may be placed near t the latter. In this instance the travellerguide 11 is in the lower position of its movement and theloading strand of yarn 12 is shown passing therethrough to and partly around the spool barrel, thence through the slot 8 to the outside face of the spool head and then over the latter to the two slipcatches around which its end is looped several times against slippage (see Fig. 5). Otherwise, the special loading of the spool is the same as the other, and these spools when loaded are arranged for magazine feed of the yarn. in exactly the same way as hereinbefore described with reference to said other form of spool.

In spools of the modified form having heads of a diameter substantially greater than the supporting cup of the winding s indle, the

e peripheral edge of the head beyond the edge of said cup, rather than close to the plug so as to be encompassed by the cup"as herein shown.

Obviously, spools adapted for loading with the innermost end of the yarn thereon ex tending outwardly from thebarrel may be made in various forms without departing from the spirit and scope of this invention, the essential purpose of which is to provide for fastening the yarn end to the outside of the spool without extending it across the inner face of either head and b means which will not allow entanglement uring loading nor cause breakage of the yarn or other spools when put in use and thrown about. Accordingly, while certain restrictions are necessarily imposed, it is, not intended that the invention shall be limited by the appended claims to the specific construction shown and described.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

In a spool embodying a barrel having disc-like heads of a diameter substantially greater thanitsbarrel, means adapting the end of-the innermost winding of yarn strand thereon to be extended outwardly to and fastened at the outer side'of one of its heads without passing such end across the inside face of such head; said means including a point of said groove on narrow'radial slot through said one of the heads from a oint in the latters periphery to a point of 1ts juncture with the barrel, a short axial extension of the barrel beyond the face of said head, a peripheral groove in said extension close to the outer surface of said head, and parallel slits across the end of said extension extending to the deepest spool axis.

2. In a warping spool embodying a barrel I having flat disk-like headsof a diameter substantially greater than the barrel, means pro- .viding for the end of the innermost winding of yarn on the barrel to be extended outwarddeepest point of said groove on opposite sides I of the spool axis.

In testimony whereof I afiix m signature.
