0., a corporation of South Carolina Application February 6, 1948, Serial No. 8,598
10 Claims.
This invention relates to improvements in bobbin construction and has more particularly to do with spools or bobbins utilized with synthetic yarn, such as rayon, in which the yarn may be wound on a bobin in a moist condition.
A primary problem in the construction of such a bobbin is due to the fact that as the yarn dries, great radial stress is placed upon the barrel of the bobbin and the axial resultant of this stress frequently loosens the bobbin heads from the barrel or in some cases deforms the bobbin itself so that it is no longer usable.
Other important requisites in such bobbin construction are the provision of a non-corrosive sur-' face for the barrel and'heads which is not subject to rust or other forms 01' metallic oxidation; furthermore, the bobbin must be light in weight and durable. Although many expedient-s have been proposed, none has enabled a satisfactory solution of all the above problems.
The present invention is characterized by a bobbin having Bakelite heads and a hollow Bakelite barrel. The barrel however. is oi laminated construction, the outer layer being a thin wall of Bakelite tubing pressed onto a reinforcing metallic sleeve. The heads are concentrically drilled and counterbored and the metallic sleeve is upset in the counterbore at each end, providing a rigid unitary construction. The metallic sleeve is internally threaded at each end of its bore and a flanged plug of Bakelite, which may be of the laminated cloth base variety, is screwed into each end of the metallic sleeve until the fiange on the plug fills the remaining space in the counterbore of each bobbin head. To provide permanent retention, the plugs are cemented into the sleeve. It will thus be apparent that this construction has no exposed metallic surfaces subject to corrosion, and is extremely light,'strong and durable.
The flanged plugs are axially drilled and one plug is provided with the conventional recess to accommodate a bobbin spindle, whereas the opposite plug has an additional counterbore at its upper end in which is expanded an annular welch washer adapted to engage the spindle top. A sleeve of plastic material connects the bores of the plugs internally of the barrel in order to facilitate insertion of the bobbin on the spindle.
" The term "bobbin is used in its generic sense since it will be apparent that the construction is adapted for spools, reels, pirns or similar devices.
A primary object of the invention therefore, is
to provide a rigid bobbin having a synthetic plastic barrel reinforced by means of an internal metallic sleeve.
i 2 A further object of the invention is to provide a synthetic plastic plug for opposite ends of the barrel of the bobbin, the plug adapted to serve as a spindle guide and also as a shield to conceal the metallic reiniorcingsleeve.
' A still further object of the invention is to pro- ;ide an improved method for fabricating 9. bobn, Further objects will be apparent from the speciflcation and drawings, in which:
Fig. 1 is a side elevation of a bobbin constructed in accordance with the invention;
Fig. 2 is a top view of the structure of Fig. 1; Fig. 3 is a bottom view of the structure of Fig. 1;
l5 and Fig. 4 is a section along the line 4-4 oi Fig. 2.
Referring now more particularly to the drawings, the barrel construction of the bobbin comprises a non-metallic sleeve II) which is preferably formed from a synthetic plastic material such as Bakelite. A metallic sleeve II is pressed into the bore 01 sleeve l0 and is provided with internal threads i 2 and I3 at each end thereof. Inner sleeve II is somewhat longer than outer sleeve ill and is adapted to be inserted through the bores in upper head l4 and lower head l5 which are counterbored at I6, Hi. When the sleeve I I has been inserted in the bores of heads I4 and I5, the sleeveis upset or rolled into counterbores Hi, I 6 to axially compress the heads against the ends of outer sleeve i0.
Upper plug I1 is constructed preferably of a canvas base laminated Bakelite material and has an axial bore l8 of sufficient diameter to provide afree-running fit on the top of a standard spindle (not shown). Plug II! is also provided with concentric counterbores l9 and 20 at its outer end. The shank of the plug is externally threaded to en gage threads l2 and sleeve H and the lower end of the plug is counterbored at 2| to provide a seat for spindle guide sleeve 22. Flange 23 on plug I! has a diameter and thickness which provide a tight sealing fit in the counterbore .IB of head It when plug I1 is turned into sleeve I i.
The lower plug 24 is constructed in a similar fashion to plug ll except that the bore 25 of plug 24 is of somewhat larger diameter than the bore I 8 of plug IT. The bore of bushing 22 is substantially the same diameter as bore 25 of plug 24 and the bore l8 flares outwardly at 26 to provide a funnel-shaped guide for the spindle to enter bore l8. Plug 24 is counterbored at 21 to accommodate the opposite end of bushing 22 in a manner similar to inner counterbore 2| on plug ll. A radially milled slot 28 at the bottom of plug 24 3 is adapted to receive the conventional lugs on the spindle base for turning the bobbins as may be desired. Plug 26. is likewise externally threaded to engage threads 13 on sleeve l2 and flange 29 on the plug completely fills the remainder of counterbore IS in lower head l when the plug is threaded and cemented in place in sleeve 1 I.
An annular welch washer 3| is expandedinto counterbore of head 16 and serves as a bearing contact between plug l1 and the upper end of the spindle. The depth of counterbore 19 provides the necessary relief for the expanding of washer 31 in counterbore 26, assuring retention during steaming of yarn.
It will thus be apparent that I' have provided bobbin construction of light weight which will not come apart in service. The barrel of the bobbin is both non-corrosive and incompressible. The lightweight spindle guide in the barrel permits a hollow construction which will at the same time provide means for readily inserting the bobbin on the spindle. The cemented plugs reinforce the barrel and the heads and completely seal the metallic sleeve within the barrel and heads. Furthermore, the construction enables satisfactory V bobbins to be made which are extremely inexpensive and durable.
