ABSTRACT:
A device designed to extract heat from a fire or flames, and by the principle of conduction and convection channel this same heat into the desired or required area or system. The principle used is to immerse the structural members which are formed from materials which are good conductors of heat and resistant to deterioration or destruction by the temperatures found in fire, heat, or flames and have the structural members provide the heat where so desired. The structural members may be of solid construction throughout or they may be fashioned from hollow members with a gaseous or liquid type conductor or convector of heat of the heat pipe type within the same structural members. As the portion of the structural members contained in the fire absorb heat, this heat will be conducted to where it is desired by the aforementioned principle of conduction or convection.
There is an air deflection system composed of two parts, one of which is the cooking plate and the other the curved deflector surface. The cooking plate which is capable of being latched in an angular position serves as an air deflector when in that position, but when the latch is released and the cooking plate laid flat on the structural members, enough heat may be obtained for the purpose of cooking or other use. The air deflector plate may be curved or flat, metallic or glasseous in nature and may be selectively positioned from tightly against the fireplace opening to a multitudinous number of positions to effectively act as an air shield or barrier thereby preventing the selective portion of warmed or unwarmed room air from entering the fireplace.
