I Renewed April 28,193! I 3 Claims. (0!. 112451) My invention relates to bobbins for sewing machine shuttles and to a method of producing thesame, and'has for itshbj'ectthe production ota, novel and improved bobbin of this character.
, 6- I {Iheiollowing is a description of my invention,
7 reference being had to the accompanying drawing, in which: 1
bobbin in its preferred form;
Figure 1 is a view in perspective of my improved 1o Pig. 2 is a longitudinal sectional view on an 7 20 1,481,243, dated January 15, 1924.
As shown, the bobbin is provided with a tubular core on which is a cross-wound mass of thread l. Fitted on the ends of the core in close contact with the ends 01' the thread mass, are annular In accordance with the present invention, core is preferably made of sheet metal, such as aluminum, and may beiormed either as a split Htubeoraseamlesstube. 3o Inthe iorm shown in the drawing, after the g disks 8 of resilientpaper.
disks 0 are placed on the ends of the core against, disk. 7 V i 3. The method of forminga filled bobbin which comprises winding thread into a mass on a tubular the ends of the mass, the ends 01' the core are upset or swaged so as to hold the disks in place.
'A series of projections I spaced' circumierentially about the core. are then struck outwardlyso as to-cause them to dent into theinner edge of the inner periphery of the disks.
- With this construction'it will be apparent that the disks are securely gripped between the swaged 0 ads of the core and the projections I so as to hold the disksin position axially or the core and prevent them from moving inwardly or getting out of place as the thread .is unwound tions into thedisks securely hold the disks from turning with relation to the core.
As will be evidentto 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: v 1. In a fllled'bobbin having a tubular-core having thread cross-wound thereon in a mass, and
; disks-of resilient material on the ends of said core, the improvement which comprises said core 7 being provided at each end with a series of out wardly struck projections. indented into-the inner edge of the inner periphery of the associated disk,
.i'rom the core. Also the indenting er the projecand the endsofthe core being swaged so as to secure thedisks against the ends of the thread mass.
2. The method of forming a filled bobbin which 1 comprises cross-winding thread into a mass on I a tubular core of, sheet metal, placing 'annual disks .on the ends or the core against the ends or the mass, swa'ging the ends of the core to hold the disks against the mass, and forming a plurality of spaced outward projections in the sheet metal coreagainst the inner edge oi" the] inner periphery of each of the disks, so as to cause said projections to be indented into the core of sheet metal, placing annular disks on the ends of the core against the ends of they mass, swaging the ends of the core to'hold the disks against the ends of the mass, and thereafter forming outward projections on the core so" as to cause the disks to be held between said projec- CERTIFICATE foF comczuon. 7
