Appeal No. 98-0584
Application 08/238,948
provided an ample suggestion to one of ordinary skill in this
art to substitute in Hewitt for his contact-type detector a
magnetic proximity-type detector as taught by Lieber.
Claims 2 and 33 are rejected under 35 U.S.C. § 103 are
rejected as being unpatentable over Hewitt in view of Lieber
as applied in claims 1, 6, 7, 32, 37 and 38 above and in
further view of the Delta instruction manual. Hewitt does not
teach an insert for the blade aperture; however, the Delta
instruction manual clearly teaches that the provision of an
enlarged blade aperture and insert are well known expedients
in the art of table saws (see, e.g., Fig. 46). In our view,
one of ordinary skill in this art would have found it obvious
to provide the table saw of Hewitt, as modified by Lieber,
with an enlarged aperture and insert as taught by the Delta
instruction manual in order to achieve the self-evident
advantage of easy access to the saw blade.
In summary:
The examiner's rejections are all reversed.
