On this day in 1941 Moritz L. Mueller was granted the Patent for FURNACE. U.S. Patent No. 2,263,098.
This invention relates generally to furnaces and has particular reference to a furnace which is arranged to positively circulate and filter the air being heated.
It is an object of this invention to provide a furnace in which the novel arrangement of the parts of the furnace provide for an efficient and compactly arranged furnace so that the overall dimensions are relatively small.
It is another object of this invention to provide a furnace which may be prefabricated in sections so that very little work is required in the field to assemble the furnace.
It is another object of this invention to provide heat exchange surfaces within a furnace in such a manner as to make use of practically all the heat generated by the burner. It is another object of this invention to provide a furnace in which the draft within the combustion chamber is maintained at a relatively constant figure by means of a suction blower in the exhaust passage to the chimney.
It is another object of this invention to provide a furnace in which power for the process of combustion and power for circulating the air being heated is provided by a single motor.
