Appeal No. 97-1973
Application No. 08/248,003
example, Figure 6.
Von Bolhar discloses a dredge digging structure having
buckets 81 mounted on a plurality of link bodies 51 of an
endless chain 21. In order to mount the buckets 81 on the
link bodies 51, the side walls of the buckets are provided
with lugs 86 and 87 having reenforcing flanges 88 and 89 and
terminate in bosses 90 and 91. When assembled to the chain,
the bosses 90 and 91 are aligned with bosses 93 and 94 located
on the lateral faces of the link bodies 51. See col. 4, lines
31-43.
Appellants argue, inter alia, that none of the applied
references teach "an upright edge 'engaging and supporting' a
rib as recited" (brief, page 6). In response, the examiner4
argues that
Whisler places upright edges on the lower wheel and Von
Bolhar changes the location of Gray's ribs to be between
the chain and the upright edges, thus allowing the
upright edges to engage and support the ribs. (answer,
page 5)
As indicated above, the examiner asserts that one of ordinary
4Claim 4 actually calls for "upright edges on the lower wheel engaging
and supporting the ribs" (emphasis supplied).
