Abstract
A disk, having a larger diameter than the diameter of a roof vent aperture to be closed, supports an annular resilient member in contact with the inner surface of the roof around the aperture. The disk is held in place by a resilient member extending between the disk and a structural portion of a ventilating apparatus.
Claims1
In combination with a wind driven turbine attic ventilator overlying a roof having an inner surface and having a ventilating aperture, the improvement comprising:
- a generally flat disk underlying the roof in surrounding relation with respect to the aperture therein for closing said aperture,
- said disk having a pair of concentric flanges adjacent its periphery forming a substantially U-shaped groove open toward the inner surface of said roof;
- a seal formed from resilient material coextensive with the groove and projecting beyond said flanges for sealing with the inner surface of said roof;
- and,
- a resilient member extending between and connecting said disk with a peripheral portion of said attic ventilator in a manner to prevent the normal angular rotation of said turbine.
