Appeal No. 1998-0106
Application No. 08/377,753
for our review is the propriety of the examiner=s rejection
of claims 15-18, 20-22, 24 and 26.
Appellants= invention relates to A[a] universal joint
coupling, especially for use on a universal joint shaft
(10) of an eccentric worm machine@ (claim 15, lines 1-2).
According to claim 15, the only independent claim on
appeal, the universal joint coupling comprises inner and
outer, torque-transmitting gear ring members (16, 26).
External teeth on the inner gear member mesh with internal
teeth on the outer gear member to provide for the
transmission of torque.
Claim 15 additionally recites that the universal joint
coupling includes a pair of axial force transmitting
members, with each pair comprising a spherical cup (22) and
a ball segment (24) supported in the cup. As disclosed in
appellants= specification (see page 9), the outer gear ring
and the spherical cups are non-rotatably attached to a
housing (20) by feather keys (30a, 30b). Claim 15
specifies that the inner gear ring and the ball segments
are integral parts of a hub (16).
