Appeal No. 1999-0050
Application 08/499,111
the Jeschke gripper cylinder does not meet the limitations in
claim 1 requiring each gripper base to be configured as a
roller having a periphery formed of a plurality of surfaces at
different distances from a center of the roller. Jeschke’s
gripper bases 8 are beam-like structures which are adjustably
supported for
movement generally along their longitudinal axes. The
examiner’s reliance on Kirn to cure this deficiency in Jeschke
is not well founded.
Kirn discloses a variable speed percussion drilling
machine having an eccentrically-mounted prismatic portion 139
which can be turned to adjust the axial position and operation
of a tool holder shaft 127 (see column 6, lines 8 through 61).
According to the examiner,
Kirn et al. disclose the old and well known concept
of providing a roller with planar surfaces (139)
that is eccentrically mounted to allow for linear
adjustment of machine elements (see col. 6, lines
13-21).
It would have been obvious to one of ordinary skill
