  • Combustion air intake system for wood-burning stove
    Patent number: 4316445
    Abstract: Hinged doors are provided on the front of a stove for sealably closing across a large opening through which logs can be loaded into a firebox within the stove. A cylindrical draft chamber is formed on an exterior surface of one or each of the doors. A draft cap is rotatable on a threaded stud which is coaxially secured in the cylindrical draft chamber. The draft cap includes an annular flange forming a sliding close-tolerance fit with an interior cylindrical wall of the draft chamber so that the cap can be rotated to vary the size of the draft chamber to selectively restrict the flow of air from a source through the draft chamber to the firebox whenever the doors are closed.
