Abstract
A flat circular base having a ball bearing, comprising co-planar inner and outer races, the outer race of which is co-axially mounted on said base, the inner race of said bearing supporting a tubular skein holding mast having a circular sheet masonite platform fixed thereon in close spaced relation with said base. A skein of yarn assembled about a given axis is applied axially to said mast so that the skein and mast freely rotate as the yarn is used in crocheting or knitting. The mast is hollow and also provides a storage receptacle for crocheting needles.

A direct-from-the-skein yarn feeder comprising:
- a base comprising a circular flat block of pressed wood or the like, having a central bore and a counterbore;
- a bearing on said base, said bearing comprising a radial ball bearing with co-planar inner and outer races, said outer race fitting in said counterbore;
- a skein mounting mast, said mast comprising a cylindrical tube, the lower end whereof having inserted upwardly therein a wooden plug which also fits downwardly into said inner race and thereby journals in said bearing;
- a skein supporting platform fixed on said mast near the lower end thereof, said mast and platform freely rotating with a skein mounted thereon as yarn is withdrawn from said skein;
- means for securing said inner race to said plug;
- means for securing said outer race rigidly to said base;
- and
- a short tubular collar of approximately the same inside diameter as said tubular mast fitting said plug so as to itself rest on the upper end of said inner bearing race,
- said platform being formed of thin sheet material and having a central hole with the same inside diameter as said tubular mast,
- said platform fitting said plug and being assembled thereon between said mast and said collar so as to be snugly gripped between said mast and said collar and said inner race when said plug is assembled as aforesaid on said inner race.
