Appeal No. 99-0201
Application No. 08/696,283
cam contacting surface including a central
cylindrical portion and curved edge surfaces at said
axial ends of said cam contacting surface, said
curved edge surfaces having a constant radius of
curvature, said curved edges [sic, edge surfaces]
extending over an axial distance that is a
substantial portion of the axial length of said cam
contacting surface.
Similar language appears in claim 9, the other independent
claim.
The examiner finds in Majewski all of the structure
recited in claim 1 except for the curved edge surfaces. It is
the examiner’s position that this feature is taught by
Guilford, and that it would have been obvious to one of
ordinary skill in the art to curve the edges of the Majewski
roller in view of the teachings of Guilford.
Majewski discloses a roller for a brake actuating cam,
although the focus of the patent is on retaining the roller
rather than the problem attacked by the appellant, which is
not even mentioned in Majewski. As shown in Figure 3, each
Majewski roller comprises a cylindrical roller surface 21,
which is flanked by tapered portions (unnumbered), ends 52,
and cylindrical trunnions 22. The edges of the roller
surfaces clearly are not curved.
