Appeal No. 2006-2116
Application No. 08/879,517
(b) transmission means through which said motor shaft is
connected to said saw shaft so that an axis of said motor
shaft is shifted from an axis of said saw shaft by a distance
which is greater than or equal to the radius of said circular
saw blade, wherein when said holder is tilted in either of
said opposite directions by an angle greater than or equal
to 45 degrees with respect to the zero-tilt angle position,
said housing does not contact said top surface of said base.
10 The motor shaft and saw shaft of the desk-top cutting machine
labeled prior art and depicted in appellant’s Figures 6 and 7 are
extensions of the same shaft. Thus, the motor and saw blade
shafts lie in a single plane. It would have been apparent to a
person having ordinary skill in the art therefrom that the housing
for the motor driving the motor shaft, depending on the sizes of
the motor and its housing, likely would deny saw blade cuts 45
degrees to either side of zero-tilt unless the workpiece was
turned around. The housing for the motor driving the motor shaft
would abut the top surface of the workpiece base when the saw
20 blade attempts one of the two 45 degree cuts to either side of
zero-tilt.
The motor shafts and the distinct saw blade shafts of the
desk-top cutting machines encompassed by appellant’s Claim 1 and
described by Ito both were positioned to prevent the housing for
the motor driving the motor shaft from ever abutting the top
