Miller, J N

A device is presented for preventing blow back through the fuel loading door in stoves or heaters in which the rate of combustion is controlled by restricting the supply of air to the combustion chamber. When the stove is burning during normal operation the fuel loading door is closed and an air inlet to the combustion chamber is blocked by a pan member of the outer cabinet door. A thermostatic damper controls the rate of combustion in the combustion chamber by restricting the quantity of air supplied via other air intakes. When the outer cabinet door is opened to gain access to the fuel loading door, the pan member on the cabinet door is moved away from the air inlet to the combustion chamber thereby allowing additional air to enter the combustion chamber via the air inlet to the combustion chamber. The additional air supplied via this air inlet increases the rate of combustion prior to the opening of the fuel loading door. This increased combustion rate is unaffected by the opening of the fuel loading door, and the flames, smoke and other products of combustion are not blown back through the fuel loading door when it is opened.
