Abstract
A thread winder having a hollow sphere divided into two halves with a spool inside concentric with the sphere. The sphere is carried on a yoke so that it can be swung about one of its axis and one-half of the sphere is rotated about the axis perpendicular to the equator line where the two halves join. The spool is rotated inside the sphere and yarn is fed through an opening in the rotatable half of the sphere. Thus, as the sphere swings and the spool rotates, the thread is wound on the spool and distributed by the swinging movement of the sphere relative to the spool.
Claims5
A yarn winder comprising,
- a support,
- a stem rotatably fixed to said support,
- a ring gear and pinion adapted to rotate the stem relative to said support,
- a yoke adapted to support a sphere,
- a sphere having a fixed hemisphere and a rotatable hemisphere,
- said fixed hemisphere being fixed to said yoke and said rotatable hemisphere being rotatable about an equator line of said fixed hemisphere,
- said stem extending through a slot in said fixed hemisphere and a slot in said yoke,
- a spool on said stem inside said sphere,
- a connecting rod,
- pivot means connecting a first end of said connecting rod to said yoke and a second end of said connecting rod connected to said ring gear adjacent the periphery thereof,
- rotating means on said yoke driving said rotatable hemisphere along said equator line,
- a hole in said rotatable hemisphere disposed on a radius displaced approxmately five (5) degrees from a radius perpendicular to said equator,
- said hole being adapted to receive a thread to be wound on said spool,
- said equator of said sphere being adapted to rock relative to said stem as said pinion rotates said spool whereby said thread is distributed over said spool.
