Appeal No. 96-3745
Application 08/269,916
Sells teaches baffles 22 (perforated with air flow holes 24)
interposed between a cover plate 20 and a roof, and defining
compartments therewith as depicted.
The Garries patent discloses a ventilator system for a
building attic. While the patentee in the preferred form of
the invention provides a ventilator system at one or both ends
of a roof gable, it is expressly indicated (column 4, lines 58
through 60) that
the same principles are equally applicable
to cupolas and ridge vent type ventilator
systems used to vent the ridgeline of a
roof.
In particular, Garries teaches (column 2, lines 20 through 31,
and column 7, lines 20 through 35) those having ordinary skill
in the ventilator art to include a flapper valve 55 in an air
passage to prevent water blow-through under higher than normal
wind conditions or when the ventilator is subjected to high
wind gusts.
