  • This invention relates to a bobbin hanger, More particularly, this invention relates to a bobbin hanger for a spinning machine, adapted to rotatably hang onto a hanging rail and permitting easy attachment and detachment of a bobbin.
  • bobbin hangers In response to such requirements, many kinds of bobbin hangers have been devised so far, among which the most popular type is provided with paws rotatably pivoted in the lower part of a hanger body, which paws rest on the shoulder of a bobbin to hook it. More specifically, a cylindrical shell of shell of a hanger body is of split construction, each mate being provided with like cam grooves inside, along which a camshaft moves up and dow with a pair of paws coupled in the lower end, which camshaft is movable in association with a handoperated slider fitted around the shell, thereby causing the paws to spread and contract to engage and disengage the shoulder of a bobbin.
  • a bobbin hanger having a pair of legs inserted inside a cylindrical shell of the body, said legs being provided with a paw at the top portion, which legs is slidable in association with the movement of a slider fitted around the shell, thereby causing the pair of legs to forcibly spread when the lowering-legs finally comes in contact with an appropriate inverse V'shaped means installed in the lower end of the shell, wherein the paws extending outside theshell engage the shoulders of a bobbin to hang on it.
  • This invention is similar to those conventional devices in that the paws are pivotally mounted in the lower end of a hanger body in conjunction with the movement of a slider fitted around the body of a anger, so as to engage and disengage the shoulder of a bobbin. But this invention has quite new constructual and operational features in respect to the paws.
  • An object of this invention is to provide a bobbin hanger which can easily and securely support bobbins of various diameters without any special skill.
  • Another object of this invention is to provide a bobbin hanger which protects the thread from tangles and breakage as it is withdrawn from the individual bobbin.
  • a further object of this invention is to provide a bobbin hanger which automatically controls a blind rotation of a hanger unsynchronous with a drawing speed of thread, so as to prevent possible tangles and breakages of thread.
  • a still further object of this invention is to provide a bobbin hanger of simple internal construction, resulting in a simplified process of assembly which leads tomass production with reduced unit costs.
  • a still further object of this invention is to provide a bobbin hanger requiring no special working skill, making it easily handled by anyone.
  • a bobbin hanger of this invention consists essentially of a cup-shaped cover having a hanging rod adjustably screwed thereto, a cap body rotatably supported by said hanging rod extending inside the cover, a hanger body received in the cap body, which hanger body has a fixed clutch and a movable clutch installed in a bore of the body, a vertical bar extending in a bore of the fixed clutch with a spring interposed therebetween, said movable clutch being raised up in association with the movement of a slider fitted around the body when the latter is pushed upwardly by hand.
