Abstract
A flyer assembly including a spindle rotatable about an axis of rotation, an arm coupled to the spindle, a level wind device axially mounted to the arm, a first friction member disposed along a width of the level wind device and shaped into a convex curve defining the width of the level wind device, a second friction member offset from the first friction member, and a fulcrum having an eye or hook.
Claims14
A flyer assembly including a spindle rotatable about an axis of rotation, comprising:
- a bobbin onto which yarn is spooled in operation of a spinning wheel used to spool, twist, and store the yarn, the bobbin comprising a shaft of the spindle, the spindle having a flanged distal end journaled to a flyer head comprising a whorl pulley in conjunction with a drive band to cause the flyer assembly to rotate about the axis, the spindle rotatable about the axis relative to a rate of rotation of the flyer assembly;
- a pair of hollow cylindrical arms radially spaced from the axis and disposed in diametric opposition to one another while extending substantially parallel to the axis, each of the pair of cylindrical arms having a proximal end and a distal end, each distal end removably coupled to the flyer head of the flyer assembly and each proximal end removably coupled to a hook orifice bar of the flyer assembly;
- and
- a level wind device axially mounted to the first cylindrical arm of the pair of cylindrical arms and disposed along a length of the first cylindrical arm of the flyer assembly, the level wind device comprising a traversal rod disposed along a width of the level wind device, the yarn evenly distributed onto the bobbin in a level wind pattern, wherein the traversal rod of the level wind device comprises a convex curve defining the width of the level wind device, the yarn frictionally engages the convex curve of the traversal rod along a length of the convex curve from one end to another, back and forth, in a sweeping fashion in operation of the spinning wheel.

An apparatus including a spindle having an axis of rotation, comprising:
- an arm coupled to the spindle and radially spaced from the axis of rotation extending substantially parallel to the axis, comprising:
- a level wind device axially mounted to the arm;
- a first friction member disposed along a width of the level wind device and shaped into a convex curve defining the width of the level wind device;
- a second friction member offset from the first friction member linearly extending along the width of the level wind device;
- and
- a fulcrum having an eye or hook, the fulcrum pivotally adjustable, wherein a material of length threaded through the eye or the hook of the fulcrum frictionally engages the first friction member followed by the second friction member in an operation of spooling the material around the spindle, the spindle rotatable about the axis to receive the material from the second friction member.
