Appeal No. 97-1703
Application 08/382,432
Claims 9 through 12 stand rejected under 35 U.S.C. § 103 as
being unpatentable over Douglass in view of Korsch.2
Reference is made to the appellants’ main and reply briefs
(Paper Nos. 14 and 16) and to the examiner’s answer (Paper No.
15) for the respective positions of the appellants and the
examiner with regard to the merits of this rejection.
Douglass discloses a method and apparatus for machining
nonaxisymmetric surfaces on a workpiece mounted on a rotating
spindle. As described by Douglass,
the machine tool comprises a generally T-shaped base 18
upon which an X slide 20 and a Y slide 22 are mounted
in a suitable conventional manner for displacement in
any desired manner along planes disposed perpendicular
to one another as conventionally practiced. The Y
slide 22 is provided with a conventional spindle
mechanism generally shown at 24 and which is rotated by
a suitable drive motor shown at 26.
A third slide or auxiliary slide referred to
herein as the Z slide is shown at 28 and is movably
mounted on the X slide 20. The Z slide 28 is shown
supporting a conventional tool holder 30 and metal-
working tool 32 for machining the surface 12 of the
workpiece 10 upon contact therewith.
2In the final rejection (Paper No. 6), claims 9 through 12
also were rejected under 35 U.S.C. § 112, second paragraph. Upon
reconsideration, the examiner has withdrawn this rejection (see
the advisory action dated July 30, 1996, Paper No. 10).
