We will not sustain the rejection of claim 12 under 35 U.S.C. § 103 as being
unpatentable over McCormack in view of Gray.
Claim 12 reads as follows:
A Iathe assembly comprising:
a base unit having first and second Iongitudinal ends,
a headstock assembly provided adjacent said first Iongitudinal 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 Iongitudinally in a direction parallel to said Iongitudinal axis of
said spindle for slidably receiving at least 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 second base unit mounted to and supporting a longitudinal end of said
second Iathe bed assembly remote from said first base unit.
