Appeal No. 96-3702
Application 08/208,688
This appeal is from the final rejection of claims 1 through
21, all of the claims pending in this application for the reissue
of U.S. Patent No. 5,255,435.
The invention relates to “a method and apparatus for
removing bearings, such as automatic transmission bearing cones
or bearing cups wherein the apparatus is adjustable to
accommodate bearings of any size or diameter for removal by
contacting the cup or cone on inner or outer surfaces thereof”
(specification, column 1, lines 6 through 11). Claims 14 and 21
are of particular concern in this appeal and read as follows:
14. 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;
[tapered] adjusting means 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.
