Application No. 08/605,212
knife 10 arranged on lower lever 9; a holder 1 on which the
upper and lower levers are coaxially and pivotally mounted;
connecting rods 24 and 25; cranks 26 and 27; gearwheels 29;
and a hydraulic motor 30 connected to one of the gearwheels 29
to impart rotation motion thereto.
The examiner determined (answer, pp. 4-6) that both Ward
and Gurevich clearly teach all the claimed limitations of
claim 16 except for the limitation "a separate powered drive
coupled to each said shear arm to pivotally move said first
and second shear arms in synchronism with each other to sever
the glass gobs." With respect to this limitation the examiner
set forth two alternative approaches. The first approach
being that it would have been obvious at the time the
invention was made to a person having ordinary skill in the
art to replace the single drive motor of Ward or Gurevich with
two drive motors so as to provide for individual control of
each shear arm in view of a lack of any unexpected results or
criticalities. The second approach being that the claimed
limitation was met by Ward's gears 56 and 58 and Gurevich's
cranks 26 and 27 driven by gearwheels 29.
