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.
