Abstract
A lathe for blowing glass. The lathe includes a lower section and an upper section removably attached to the lower section to form a housing. A motor is operably connected to a gear assembly. At least one roller assembly rotatably supports a blowpipe. An air coupling assembly rotatably attached to the gear assembly allows air to pass from a blowhose to an air tube frictionally engaging the blowpipe. A sprinkler system may be provided for cooling the blowpipe while the article is being formed. The speed and direction of rotation of the blowpipe can be manually or remotely controlled by the glassmaker. Thus, the lathe is capable of rotating the blowpipe while air is being provided to the blowpipe to form the article.
Claims23
An apparatus for rotating a blowpipe while blowing a glass article, comprising:
- a lower section;
- an upper section removably attached to said lower section;
- a motor mounted on said lower section, said motor having an output shaft;
- a gear assembly mounted on said upper section and operably connected to the output shaft of said motor;
- at least one roller assembly mounted on said upper section for rotatably supporting a blowpipe;
- an air coupling assembly having an input and an output, said air coupling assembly rotatably attached to said gear assembly;
- an air tube connected to the output of said air coupling assembly, said air tube frictionally engaging the blowpipe;
- and
- a blowhose connected to the input of said air coupling assembly,
- wherein said apparatus is capable of rotating the blowpipe while blowing the glass article.
A lathe for rotating a blowpipe, comprising:
- a housing;
- a motor disposed within said housing, said motor having an output shaft;
- a gear assembly operably connected to the output shaft of said motor;
- an air coupling assembly rotatably attached to said gear assembly;
- a blowhose connected to an input of said air coupling assembly;
- and
- an air tube connected to an output of said air coupling assembly for frictionally engaging the blowpipe,
- wherein said lathe is capable of rotating the blowpipe while air is being provided to the blowpipe.
A lathe for rotating a blowpipe, comprising:
- means for supporting a blowpipe;
- means for rotating the blowpipe;
- means for providing air to the blowpipe;
- and
- means for cooling the blowpipe.
A portable lathe for blowing glass, comprising:
- a motor having an output shaft;
- a gear assembly operably connected to the output shaft of said motor;
- an air coupling assembly operably connected to said gear assembly;
- a blowhose operably connected to an input of said air coupling assembly;
- and
- a blowpipe operably connected to an output of said air coupling assembly,
- wherein said lathe is capable of rotating said blowpipe while air is being provided to said blowpipe.
