described what I now consider to represent its best embodi
ment. However, I desire to have it understood that within
the scope of the appended claims, the invention may be
practiced otherwise than as speci?cally illustrated and
described.
I claim:
1. In a ventilator having a base including side walls
ments one each disposed between a pair of said support ele
ments and each including opposed ends pivotally secured
to said pair of support elements for rotation about an axis
substantially parallel to said side walls, the axis of each
said damper element being in substantial alignment with
the axes of the remaining damper elements, said ends in
55 cluding a face disposed substantially normal to the axis
Since the support elements 53 are inclined (see FIG
URE 7), the gutter means 20 is likewise inclined with
its lowermost end extending beyond the side wall 46.
Thus when the damper elements 54a, 54b are in the
closed position (see FIGURE 7), any water that enters
the ventilator 44 and deposits on the gutter means 2%}
will be directed along the gutter means 20 for dis
charge therefrom onto the roof 49.
FIGURE 8 illustrates the position which the wiper
?anges 28 assume when the gutter means 20 is installed.
However, in FIGURES 9 and 10 the wiper ?anges 28
are illustrated in their normal positions, i.e., once the
damper elements 54 have been pivoted to their open posi
tion 54’ (see FIGURE 7) and closed again.
70
FIGURES 9 and 10 are cross-section views taken along
opposed sides of the axis 56. As the damper element
54 pivots in an opening direction it moves upwardly
with respect to one side of the axis 56 (FIGURE 10)
and downwardly with respect to the other side of the 75
of said damper, means connected to a group of said damper
elements for pivoting the said group as a unit about their
respective axes, and stationary gutter means extending be
tween adjacent faces of adjacent damper elements for
light-proo?ng the said ventilator, the improvement in said
stationary gutter means comprising:
a unitary strip of resilient rubber-like material including
opposed laterally displaceable L-shaped portions each
having a vertical leg and a horizontal leg,
a bendable central portion having terminal side edges
contiguous with said horizontal legs, and
at least one wiper ?ange on each said vertical leg dis
posed in outboard relation to said horizontal leg,
said opposed L-shaped portions having said horizontal
legs secured to one of said support elements,
said wiper ?anges being in wiping contact with said ad
jacent faces when said adjacent faces are pivoted into
engagement therewith.
2. The improvement of claim 1 wherein the thickness

of said bendable central portion is less than the thickness

of said opposed L-shaped portions.
said gutter means.
3. The improvement of claim 2 wherein the said bend
able central portion is arcuately shaped whereby the said
wiper ?anges are biased away from each other.
4. The improvement of claim 1 including a plurality
of wiper ?anges on each said vertical leg disposed in out
board relation to the said horizontal leg.
5. The improvement of claim 4 wherein the outer edges
of the said wiper ?anges lie in a plane, said plane being 10
inclined with respect to said vertical leg.
6. The improvement of claim 1 including fastening
means extending through said horizontal legs into said
