  • Patent number: 5957373
    Abstract: A ventilator is selectively configured so that it can automatically open and close its louvers according to the temperature in its environment or have its louvers manually positioned in either the open or closed orientation. The louvers are disposed in an air passageway that is defined by a housing. A bimetallic coil acts through a drive element and a linkage element to automatically open and close the louvers of the ventilator. A pair of override members have respective handles accessible to the user. Manipulation of the override members enables the user to override the automatic drive element to manually open and close the louvers.

  • Patent number: 5294049
    Abstract: An adaptable, temperature-responsive, powered-fan, foundation ventilator apparatus includes a louver housing defining an air passageway, construction for selectively opening and closing the louver housing air passageway depending upon the temperature, a fan housing defining an air passageway communicating with the louver housing, structure for mounting a fan at the rear edge of the fan housing, a fan carried by the fan mounting structure, a fan orifice plate disposed across the air passageway of the fan housing and defining an orifice through the orifice plate, and a fan that includes a fan blade operatively disposed in the orifice of the orifice plate. The apparatus further includes a flexible elongated duct that connects the fan housing to locations which are obstructed from direct flow to the fan housing. The apparatus further includes a flexible adaptor hood which adjustably connects to the fan housing and to the flexible duct and is configured for easy storage in inventory.

  • Patent number: 4699045
    Abstract: The housing of a foundation ventilator has the usual front screen to protect the louvres within the housing, but the screen is part of a support frame used to mount the ventilator in an opening in a foundation wall. The support frame is frictionally retained in the opening by threaded bolts which can be easily loosened to gain access to the interior of the housing for cleaning or repair. It is not necessary to remove the ventilator from the wall. Similarly, if the support frame is damaged, it can be replaced without the expense of replacing the entire ventilator. The support frame has a connecting flange which seats within an extension of the housing to prevent relative lateral movement. Interlocking tabs and detents releasably attach the housing to the support frame with the screen in the support frame covering the front of the housing.
