Application No. 08/832654
the now claimed invention would not have been obvious to one
having ordinary skill in the art on the basis of the applied
prior art. The evidence before us simply fails to be
suggestive of the interrelationship between a deformable
single line edge and serrations to hold a nut against rotation
and against unintended axial withdrawal in a connector rod for
a loom, as now claimed.
As to connector rods for looms, the Corain and
Vinciguerra documents reveal the respective use of a washer,
knurling, and elastic flexible flanges to inhibit nut
rotation, notwithstanding the obvious presence in each of
these documents of what would have been understood to be an
edge of a conical wall capable of being deformed. As to the
Winnie reference, we find that it likewise lacks any
suggestion for an interrelationship between a deformable
single line edge and serrations to hold a nut against rotation
and against unintended axial withdrawal.
The patent to Nicholas addresses a sheet metal nut and a
threaded screw member within the bore of a supporting part to
