On this day in 1900 Amos C. Steere was granted the patent for HEATER. U.S. Patent No. 641,805.
The object of this invention is to provide an economical and efficient air-heater, and while this invention is particularly adapted for a heater in which gas is employed as a fuel it can with proper modifications be used with coal, wood, or other fuel.
In the ordinary forms of stove there is a great waste of fuel, due to the rapid flow of the products of combustion to the chimney and to the fact that the products of combustion are not made to heat large areas of heating-surfaces. These faults are remedied by making the products of combustion take a sinuous course to the outlet and providing in the path of their flow large areas to be heated. Further, these air-heating surfaces are inclined so that the flow of air over or through the surfaces is facilitated.
