Potter's wheelhead assembly with relocatable axis of rotation

A wheelhead assembly for use upon a vertical rotary drive shaft of a potter's wheel, said wheelhead assembly comprising:

• (a) a top plate having an upper surface for mounting a mass of clay to be molded into an article of pottery;
• (b) a drive shaft coupler having a fixed axis of rotation and supporting said top plate upon the rotary drive shaft of the potter's wheel for rotation with said coupler about said axis of rotation;
• and
• (c) means for releasably securing said top plate to said drive shaft coupler and for adjustably relocating said top plate relative to said drive shaft coupler to a selected one of a multitude of different positions along orthogonal X-Y coordinates defined by said securing and relocating means to thereby relocate said axis of rotation of said top plate relative to said drive shaft coupler to said selected one position along said orthogonal X-Y coordinates;
• (d) said securing and relocating means including a bottom plate having a central opening and being attached, and disposed adjacent, to said top plate, said drive shaft coupler extending through said central opening of said bottom plate.

A wheelhead assembly for use upon a vertical rotary drive shaft of a potter's wheel, said wheelhead assembly comprising:

• (a) means defining an upper surface for mounting a mass of clay to be molded into an article of pottery;
• (b) a drive shaft coupler having an upper mounting base supporting said upper surface defining means and a hollow coupling sleeve attached to said base and extending downwardly therefrom, said sleeve being capable of insertion over and releasably attachment to an upper end of the drive shaft of the potter's wheel, said coupler having a fixed axis of rotation and supporting said upper surface defining means on said top base of said coupler and thereby upon the rotary drive shaft of the potter's wheel for rotation with said coupler about said axis of rotation;
• and
• (c) means for releasably securing said upper surface defining means to said drive shaft coupler and for adjustably relocating said upper surface defining means relative to said drive shaft coupler to a selected one of a multitude of different positions along orthogonal X-Y coordinates defined by said securing and relocating means to thereby relocate said axis of rotation of said upper surface defining means relative to said drive shaft coupler to said selected one position along said orthogonal X-Y coordinates;
• (d) said upper surface defining means being a top plate and having a lower surface with a centrally-located circular bottom cavity recessed therein, said mounting base of said coupler being disposed in said cavity;
• (e) said securing and relocating means including a bottom plate having a central opening and being attached, and disposed adjacent, to said top plate, said coupling sleeve of said drive shaft coupler extending through said central opening of said bottom plate.
