Abstract
An automatic stove damper having a temperature responsive element which activates a damper plate, the temperature responsive element being oriented by a movable adjustment means. The device allows for easy adjustment of the relative amount of damping provided by the device by shifting the adjustment means, but if the damper plate reaches and is stopped at a fully closed position the adjustment means is allowed to shift, preventing further temperature increases from permanently deforming the temperature responsive element. The adjustment means can release the temperature responsive element to quickly shift the damper plate to a fully damped position. In other aspects of the application a metal ring is attached to a stove pipe, with a magnet being positioned thereupon for orienting the temperature responsive element to provide the desired amount of relative damping. A counterweight urges the damper plate to a fully closed position when the magnet releases the temperature responsive element.
