“locking members” with inwardly-facing “surfaces” of
“recesses” or “undercuts” in the “sidewalls” of the liquid
conduit groove (for example, page 4, line 20 to page 5, line
13). The specification (page 5, lines 10 through 13) clearly
sets forth that “clamping” of the dam in the liquid conduit
groove is “by the use of locking members that extend through
bores in the dam body member into engagement with inwardly-
facing surfaces of the undercuts.” The specification (page 6,
lines 17 through 20) further explains that the leading ends of
the clamping (locking) members tend to “gouge into the
undercut surfaces.” As additionally discussed in the
specification (page 13, line 21 to page 14, line 16), as the
screws are driven, the dam body is “effectively wedged” with
increasing “clamping forces” such that the dam assembly is
“securely locked” in the liquid conduit groove and “will not
slide about or work loose.” As additionally described in the
specification (page 14),
The combined actions of the clamping forces
described above applied to the dam body
member 50 and the frictional forces between
the interengaged locking screws 66 and
undercut surfaces 42 cause the dam assembly
