Claims
- 1. In a motor/fan damper assembly, said damper comprising a frame with a plurality of blades pivotally mounted therein to move between an open and closed position, the improvement comprising:
actuating means connected to said blades move said blades to an open and to a closed position; motor/fan means pivotal mounted to said frame; means to actuate said motor/fan means to turn the motor/fan means ON or OFF; linkage means connected to the motor/fan means and to the actuating means to cause said actuating means to move said blades to an open or a closed position depending upon whether the motor/fan means is ON or OFF.
- 2. The apparatus of claim 1 wherein the linkage means is constructed and arranged to move said blades to the open position when the motor is turned ON and force air therethrough in a direction away from the motor/fan means; and
said motor/fan means is pivoted in said frame in a direction to move it away from said blades when said motor/fan means is turned ON.
- 3. The apparatus of claim 2 wherein said motor/fan means moves towards said blades, and said blades are actuated to move to a closed position when said motor/fan means is turned OFF.
- 4. The apparatus of claim 1 wherein the linkage means is constructed and arranged to move said blades to the open position when the motor is turned ON and draw air therethrough in a direction toward the motor/fan means; and
said motor/fan means is pivoted in said frame in a direction to move it toward said blades when said motor/fan means is turned ON.
- 5. The apparatus of claim 4 wherein said motor/fan means moves away from said blades, and said blades are actuated to move to a closed position when said motor/fan means is turned OFF.
- 6. The apparatus of claim 1 wherein said motor/fan means comprises a motor attached to a fan by a pulley/belt drive.
- 7. The apparatus of claim 6 wherein said motor is mounted to a hinge connected to a spring which is connected to a frame and is arranged to pivot said motor away from said fan, such that tension is maintained on said belt.
