ABSTRACT:
An air register for mounting in a duct outlet of a forced air heating or ventilation system includes a frame carrying a plurality of pivotally movable horizontal and vertical louvers disposed in the stream of air from the duct. A generally cylindrical reel-type windmill is mounted on the frame for rotation by the stream of air about an axis disposed substantially perpendicular to the direction of the stream of air, and is coupled by a speed reducing gear train and a crank mechanism to a connecting rod interconnecting the vertical louvers for effecting continuous oscillatory movement thereof in response to rotation of the windmill by the stream of air for continuously varying the direction of the stream of air from the register. The entire apparatus is dimensioned and arranged to fit within the 23/4-inch depth of a standard room wall air duct outlet.
