Claims 14 and 16, the independent claims subject to this ground of rejection, read
as follows:
14. A Iathe assembly comprising:
a base unit having first and second Iongitudinal ends,
a headstock assembly provided adjacent said first longitudinal end of said
base unit, said headstock assembly including a spindle housing having a spindle
shaft extending therethrough,
a first Iathe bed assembly provided on said base unit and including a
bedway extending longitudinally in a direction parallel to said Iongitudinal axis of
said spindle for slidably receiving at Ieast one of a tool rest and a tailstock;
a second Iathe bed assembly detachably coupled to at Ieast one of said
first and second Iongitudinal ends of said base unit, said second bed assembly
including a second bedway for selectively receiving at Ieast one of a tailstock and
a tool rest assembly; and
a first tailstock assembly selectively slidably disposed in said first bedway,
said first tailstock assembly including a quill housing portion having a quill
assembly rotatably disposed therein and axially aligned with said spindle shaft of
said headstock assembly, and
wherein at Ieast one of the quill housing portion of the first tailstock
assembly and the spindle housing of the headstock assembly is generally
elliptically shaped in Iongitudinal section and generally circularly shaped in
transverse cross section so as to define a generally continuously curved outer
peripheral surface.
16. A lathe assembly comprising:
a first base unit having first and second Iongitudinal ends and including a
first lathe bed assembly having first and second Iongitudinal ends and a first
bedway defined therein for slidably receiving at least one of a tool rest assembly
and a tailstock assembly;
a headstock assembly mounted to said base unit, said headstock assembly
including a spindle housing portion having a spindle shaft rotatably disposed
therein;
a first tailstock assembly selectively slidably disposed in said first bedway,
said first tailstock assembly including a quill housing portion having a quill
assembly rotatably disposed therein and axially aligned with said spindle shaft of
said headstock assembly;
