Appeal No. 1999-1499
Application No. 08/764,736
A lip being absent from the teachings of Borg-Warner, the
examiner again turned to the teachings of Dutkiewicz which
shows retainer 10 which is inserted into yoke 20 between arms
20a. The retainer 10 has a "lip" 10c which, as part of
retainer 10, functions to retain bearing cups 13 on cross 12
primarily during shipping. The examiner concluded that it
would have been obvious to one of ordinary skill in the art at
the time the invention was made to have modified Borg-Warner
by providing a lip extending radially inwardly between the
yoke arms, as taught by lip 10c extending between yoke arms
20a of Dutkiewicz. In support thereof, the examiner refers to
Dutkiewicz at column 5, lines 6-8 which states:
If desired, however, the retainer 10 may be
permanently secured to the bearing cups 13 before
shipment.
In addition, the examiner makes note of column 5, lines 53-57
of Dutkiewicz which states:
If the retainer 10 is permanently secured to the
bearing cups 13, then the retainer 10 additionally
functions to limit the amount by which the bearing
cups 13 may rotate relative to the yoke 20 following
installation therein.
