Stove construction for achieving complete fuel combustion

Claim 1

A heating stove for the efficient burning of a suitable fuel such as coal or wood comprising, a stove housing defining a combustion chamber wherein combustion gases from said burning pass upwardly through a primary flue opening positioned through said housing at an upper rear portion of said chamber, a baffle disposed in said chamber at a position forward and below said primary flue opening so as to downwardly deflect said combustion gases from upper parts of said chamber into an exit zone adjacent said baffle and located within said chamber, primary draft means for introducing primary combustion air into said chamber and means for introducing secondary combustion air directly into said exit zone so as to more completely burn combustible material in said combustion gases to as to in turn reduce creosote therein and to raise the combustion efficiency of said stove, said housing including top, bottom, front, rear and connecting walls which define said combustion chamber, said primary flue opening disposed in said top wall at a position adjacent said rear wall, said primary draft means including a plurality of separate draft tubes downwardly extending from the forward portion of said top wall into said combustion chamber for directing primary combustion air downwardly towards the housing bottom wall and the base of the burning fuel supported thereby, including a swivable plate mounted on said top wall and movable to progressively cover the tops of one or more of said tubes so as to regulate the amount of primary combustion air passing into said combustion chamber.
