ABSTRACT:
A drive motor is located with its axis symmetrically between the parallel shafts on which a pair of louvers are rotatable mounted. A crank pin driven by the motor is connected to the two louver blades by drive arms attached to the upstream ends of the louver blades. A complete rotation of the motor shaft results in the louvers being relatively moved to sweep the air from an upward to a downward direction, while, at times, pinching the air to increase the throw thereof.
