Abstract
A bobbin and spool management system includes a bobbin topper having a central disc with upwardly and downwardly extending stanchions projecting therefrom, each being capped with a mushroom bolster and having a medially located chamfered collar. The upwardly projecting stanchion is adapted to mate with an axial bore in the barrel of a bobbin and retain the bobbin while the downwardly projecting stanchion is adapted to penetrate the axial bore in the barrel of a supply spool and be retained on the supply spool.
Claims7
A unitary elastic bobbin topper formed from an elastic material, said unitary elastic bobbin topper comprising:
- a central disc having a first surface and a second surface opposite the first surface;
- a bobbin stanchion extending generally perpendicularly from a central location on the first surface of said central disc, said bobbin stanchion having a first end spaced away from said central disc;
- a widened bobbin collar formed about the bobbin stanchion at a medial location spaced away from said central disc;
- a terminal cap formed closely adjacent the first end;
- a spool stanchion extending generally perpendicularly from a central location on the second surface of said central disc, said spool stanchion having a second end spaced away from said central disc;
- and
- a spool retention collar formed about said spool stanchion at a medial location spaced away from said central disc;
- wherein the central disc is at least twice as wide as the bobbin collar and the spool retention collar.
A unitary elastic bobbin topper formed from an elastic material, said unitary elastic bobbin topper comprising:
- a central disc having a first surface and a second surface opposite the first surface;
- a bobbin stanchion extending generally perpendicularly from a central location on the first surface of said central disc, said bobbin stanchion having a first end spaced away from said central disc;
- a widened bobbin collar formed about the bobbin stanchion at a medial location spaced away from said central disc;
- a spool stanchion extending generally perpendicularly from a central location on the second surface of said central disc, said spool stanchion having a second end spaced away from said central disc;
- and
- a spool retention collar formed about said spool stanchion at a medial location spaced away from said central disc;
- wherein the central disc is at least twice as wide as the bobbin collar and the spool retention collar.
