'WOUND BOBBIN AND METHOD OF PBODUOING THE SAME.
Application sied February is, i926. seriai iro. 89,299.
My invention relates to ar new and imcompressible tubular core 2 a universally proved woundbobbin and method of prowound mass 4.- (Fig. 1) and then compress diicing the same, and has for its object to the same so that the mass is somewhat comprovide a wound bobbin in which one or pressed and the core is compressed so that both heads are secured to the core by meits ends are thickened and substantially flush chanical means after the core and mass have with the adjacent portions of the end of the been axially compressed and the method for mass, as shown in Fig. 2. I then ap ly to roducing such a product. The following one or both ends of the massa cuppe head is a description of a bobbin embodying my comprising a cupped disk 8 and prongs 12. invention and the method of producing the This cupped disk 8 may be made of card- 05 same, reference being had to the accompanyboard or similar material, and the prongs ing drawings, in which 12 can be separately carried by a clip meni- Figure 1 shows in section an uncompressed ber 10 having an annular portion engaging mass-oft thread universally wound upon a the inner periphery of the disk, or the end compressible tubular core; piece and prongs may be made of one in- 70' Fig. 2`shows the same compressed, with tegral piece of metal, as shown in Figs. 6 end pieces about to be applied thereto; and 7. After the end piece has been applied, Fig. 3 shows the arts in section of a comit is subjected to pressure which brings its plete bobbin embo ying my. invention and inner surface into close contact with the produced by my method; v outer surface of the corresponding end of Fig. 4 shows the modified form of the the wound mass, the pressure slightly excomplete bobbin in which theend piece, at panding tlie cup-shaped end piece so `that one end only, is secured in accordance with it exerts a spring pressure upon the outer my invention; periphery of the ends of the mass. I then 25 Fig. 5 is a plan view of a clip employed in force the prongs outward so that the barbs 90 roduoin the bobbins of Figs. 3 and 4; 14 enter the inner surface of the core and Fig. 6 is a plan view of a modified form hold the end piece to the core and to the of head; and mass, as shown in Fig. 3.
Fig. 7 is a sectional view of the same on The end pieces at both ends of the mass so the line 7-7 of Fig.' 6 may be similarly applied and secured, as 85 Referring more particularly to the drawshown in Fig. 3, or if desired the prongs of ings, 2 is a tubular core of pasteboard or one of the. end pieces may be omitted and similar compressible material, usually used that end piece secured to the core by swagin sewing machine bobbins. l4: is a mass o ing over the ends of the core, as shown at 35 thread cross-wound thereon, the wind being 16 in Fig. 4, the end piece at the other end 0 usually known as the universal wind.

s will be evident to those skilled in' the art,'my invention permits various modifications without .departing from the spirit thereof or the scope of the appended claims.
What I claim is:
1. In the method of producing Wound bobbins, the improvement which consists in cross-Winding a mass of thread upon a compressible core, compressing said mass and core axially so as to bring one end pf said core Hush with the adjacent portion of the corresponding end of said mass, applying under pressure a cupped disk-like head having metal prongs extendin from one side thereof to said end of sai mass with the prongs Within said core, and forcin saidv prongs outward so as to embed them 1n the inner surface of said core.
In the' method of producing Wound bobbins, the improvement which consists in cross-Winding a mass of thread upon a compressible core, compressing said mass and core axially so as to bring one end of said core flush with the adjacent portion of the corresponding end of said mass, applying under pressure a cupped disk-like iead having metal prongs extendin from one side thereof to said end of sai mass with the prongs within said core so as to 'expand said cupshaped disk and cause it to exert a sprin tension on the periphery of the end ofvsai mass, and forcing said prongs outward so as to embed them in the inner surface of said core.
3. A wound bobbin comprising a compressible core, a mass of thread cross-wound thereon, the core and mass being axially compressed and each end of the core being flush with the adjacent portion of the end of said mass, a cupped head having barbed prongs extending Within said tubular core, said barbed prongs being embedded in the inner surface of said core and holding said head to said mass in Aexpanded position.
4. A wound bobbin comprising a compressible core, a mass of thread cross-wound thereon, the core andpmass being axially compressed and each end of the coreI being flush with the adjacent ortion of the end of said mass, a cupped ead having barbed prongs extending Within said 'tubular core', said barbed prongs being embedded in the inner surface of said core and holding said head in expanded position to said mass, said head comprisin a. cupped pasteboard disk and a clip memer engaging the outer surface of said disk and carrymg said prongs.
In'testimony whereof, I have signed my name to this specification this 16th day of February, 1926.
