TEXTILE spoon AND rennin.

Application filed March 3, 1928. Serial No. 258,878.

This invention relates to spools and bobbins and aims to provide a simplified and improved construction thereof.

The primary object is to produce spools and bobbins of a superior, non-breakable and durable character adapted to withstand the rough usage to which such articles are sub-- jected in various textile-mill operations.

The invention will be best understood by reference to the accompanying drawings illustrating one embodiment thereof.

Referring to the drawings, 10 denotes the barrel or stale of a spool or bobbin. Said barrel is made preferably of wood and is usually trimmed to cylindrical form. In the illustrative embodiment, both ends of the barrel are tenoned or formed with reduced extensions 10 (see Fig. 4-) through which the barrel is axially bored. The ends of the barrel are also formed with norrow recesses 11 of appropriate depth in the plane of and. .50 conforming with the peripheries of the re- In this instance, the reduced extensions and surrounding recesses in the ends of the barrel are annular but mayadvantageously be made polygonal in form.

l-Ieadsfor the ends of the barrel are shown provided by discs 12 which in this instance are of hard vulcanized-fibre or other composition resisting breakage'and rupture. Said heads are cut or punched from slabs of the component material and trimmed to desired form with central apertures 12 of shape and diameter corresponding with the recesses 11 in the barrel ends. The walls surrounding said apertures may be advantageously threaded or serrated as. represented in Fig. 1, or left smooth as shown in Fig. 6. The heads are shown also counter-recessed in one side or face to provide a ledge or shoulder 12* around their central apertures for a purpose here inafter appearing.

Means attaching the spool heads to the barrel ends s shown provided by bushings 13 adapted to fit into said ends in engagement with the heads. In the illustrative embodiment, said bushings comprise metallic sleeve-like members having their body-portions threaded or spirally .serrated as represented at 13 and formed with outwardly extended flanges 13 at one end fitting into the aforesaid counter-recesses in the spool heads. The threads in the body-portions of the bushings are formed preferably on both the inner and outer sides at a pitch sufiicient to permit aquick driving thereof into wood (see Fig.

5). In certain instances, it may also be desirable to serrate the under side of the bushng flanges as represented in said figure, while in certain instances it may also be desirable to serrate orcorrugate the periphery of'said bushing flanges so that the material thereof may impregnate or bite into the material of v the heads when driven therea ainst.

In assembling the spool, t e heads are placed with their fiat sides or faces against the ends of the barrel and with the reduced extensions of the latter projecting through their central apertures. The described bushings are then inserted within said apertures of the heads and applied over said extensions of the barrel at either end by pressure driving them into the recesses 11 with their bodyportions threadably engaging in the wood of the barrel on both sides and with their flanges 13 seated on the ledges 12 of the heads so as to lie flush with the surfaces thereof. The bushings are thus wedged into place between substantial portions of the wooden barrel with their flanges over-engaging and press ing against the outer faces of the heads so as. firmly to attach them to the barrel.

so firmly are the heads thus secured to the barrel that it is almost impossible to remove them without breaking the barrel or cracking the heads by undueforce. Moreover the heads cannot move or slip in relation to the barrel because of their tight and positive engagement therewith, especially if the undersides or peripheries of the bushing flanges are serrated to impress in the material of the heads as hereinbefore suggested. This will be true whether or not the aperture walls of the heads are threaded as represented in Fig. 1 or left smooth as shown in Fig. 6. Still greater assurance against such slippage would result from making the recesses 11. the apertures of the heads and said bushings in polygonal shape. In some instances it may also be desirable to glue-coat the bushings before driving them into the barrel ends, thus further assuring a firm unity between the parts.

A simplified and improved s 001 or bobbin is accordingly produced whic not only is non-breakable under normal conditions of rough usage in textile-mills, but is also virtually impervious to moisture and will therefore last indefinitely. Its advantages over spools of less sturdy construction in prior art developments will be quickly recognized from the economic standpoint both in manufacture and use.

Upon simple modification, the head-attaching bushings 13 may advantageously be made to serve a special work purpose adapting the spools to use as twist'ers. An embodiment thereof is illustrated in Figs. 6 to 9 wherein the modified form of bushing is shown applied to one end of a spool of construction otherwise the same as hereinbefore ,described, except that the reduced vextension of the barrel at that end is of somewhat greater length. I

' In the illustrative modified construction,

the bushing 13 for the lower or work-end of .tion on the opposite side of the the spool is shown formed with a cap-like portion 13 in prolongation of its body-porflange 13". In said cap-like portion, a central aperture 13 and a diametrical slot 13 are formed to provide for connection with a driving'element.

Ihe bushing thus formed is driven into the end of the spool barrel for attaching a head thereto in the manner already described. In

this instance the cap-like portion of said bushing engages over the reduced extension of the barrel which is correspondingly slotted and provides a ferrule-like shield therefor. Accordingly, said bushing serves a dual purpose and may be characterized as combined head-attaching means and twister-shield for the spool.

Aspool with end biishing of the modified form is obviously adaptable to connection with rotary driving means such as a twisterspindle 14 represented in, Fig. I figure, such a spool is shown slipped over the extended shank 14 of the spindle with the slot 13 of its bushing engaging over radial driving lugs 14" of thelatter in a well known manner.

The utility and advantage of the modified form of bushing combined with its value as an improved means of securing heads to a spool barrel will be readily appreciated.

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