Appeal No. 2002-1603
Application 09/320,853
projections (un-numbered) at each axial end thereof and with a
groove between the axial projections formed in the central
section of the inner circumferential surface of the roller for
holding a series of cylindrical rolling elements (8) in position
for rolling directly on the outer circumferential surface of the
trunnion.
Although conceding (reply brief, page 5) that Otsuka
arguably shows the claimed structural features of a groove and
projections on the inner circumferential surface of the roller
(5) in Figure 4, appellants contend that “the written description
of Otsuka is totally lacking any explanation or description of
each roller having an annular radial projection on a cylindrical
inner circumferential surface of the roller at each axial end
thereof” and that Otsuka does not disclose that the annular
projections of the roller and a series of rolling elements being
retained along a groove in the central section of the inner
circumferential surface of the roller form an independent
assembly that prevents the rolling elements from dispersing prior
to mounting the assembly on a trunnion.
