ABSTRACT:
A shaft extends across an air discharge opening and is rotatably mounted therein. A drive means is operatively connected to the shaft for rotating the shaft on its axis. A plurality of planar discs, are eccentrically mounted on the shaft. A pair of adjacent louver blades extending across the air discharge opening are pivotally mounted at their one edge in the air discharge opening. A spring is connected to the louver blades for biasing then into an engaging relationship with the discs such that, as the discs rotate, the louver blades are caused to rotate on their axes to cause a change in the direction of airflow emanating from the discharge opening.
