Appeal No. 96-3702
Application 08/208,688
21. Apparatus for removing a bearing without removal of an
internal mechanical part comprising:
an elongate bearing driving shaft;
contacting means axially and internally insertable through
said bearing for contacting an annular bearing undersurface, said
contacting means including a bearing-contacting shoulder, said
contacting means being connected to said elongate driving shaft
when operatively assembled for removing a bearing;
a mandrel expansion collar threadedly carried on said
driving shaft for expanding an upper portion of said contacting
means;
a mandrel spreader for adjusting said bearing driving
shoulder, from an undersurface thereof, to a desired dimension to
contact at least a portion of said annular bearing undersurface;
and
thrust means for transmitting thrust from said driving shaft
to said bearing drive shoulder such that rotation of said driving
shaft forces said bearing undersurface upwardly for removal.
In essence, these two claims are amended versions of patent
claim 14 and are identical thereto except that the term “tapered
adjusting means” in patent claim 14 has been changed to
“adjusting means” in appealed claim 14 and to “a mandrel
spreader” in appealed claim 21. The record indicates that the
appellant’s purpose in advancing appealed claims 14 and 21 is to
broaden the scope of coverage afforded by patent claim 14 (see,
for example, the “Second Supplemental Reissue Application
Declaration” submitted on October 11, 1995 as part of Paper
No. 12).
