FURNACE.
SPECIFICATION forming part of Letters Patent No. 752,068, dated February 16, 1904.
Application filed May 15, 1903.
To all whom it may concern.-
Be it known that I, VVnLLEsLny R. HAMP- DEN, a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Furnaces; andI do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to furnaces; and it is the object thereof to provide a furnace in which the products formed by imperfect combustion are mixed with air and burned before leaving the furnace.
A further object of my invention is to provide a furnace of comparatively simple construction which shall present a large heat-absorbing surface.
In the accompanying drawings, Figure 1 is a transverse section of a furnace embodying my invention, the section being taken on the line at w of Fig. 2. Fig. 2 is a longitudinal section, same being taken on the line y y of Fig. 1.
In the construction shown I employ a firepot comprising the side walls 1, which are curved toward each other at the lower edges, forming a contracted opening in which is placed the grate 2. From the sides of the grate the partition-walls 3 extend downward to the bottom of the furnace and form the ash-pit 4:.
At the upper edges of the walls 1 of thefire-pot are placed the longitudinally-extending pipes 5, which pass through the end walls of the furnace 6 and open into the air. Along the sides of said pipes are small holes 7, through which air is drawn from the pipes for the purposes hereinafter set forth.
A curved baifle-plate 8 is placed above the fire-pot and extends downward outside the walls 1 and pipes 5, as shown, thereby directing the gases from the fire-pot downward into the combustion-chamber 9. From the combustion-chamber the gases pass upward between the baffle-plate and the wall 10 and pass out at the stack-pipe 11.
A casing 12 is placed around the furnace, and in one side thereof is the coldair opening Serial No. 157,329. (No model-2 13. The air-pipes 14 pass transversely across the furnace, extending-through the furnacewalls 10, baffle-plate S, and the side walls 1 of the fire-pot, as shown.
The partition-plate 20 between the casing 12 and furnace-wall 10 directs air entering the opening 13 through the pipes 14 to the other side of the furnace into the radiatingchamber 15, from which it maybe directed through the pipes 16. to any desired point.
The operation of the furnace is as follows: A fire is started on the grate in the ordinary manner, the air-opening in the ash-pit door being left open. After the fire has started burning the air-opening in the ash-pit door is closed, and the gases distilled from the fuel, mixing with air entering through the holes '7 in the air-pipes 5, burns at this point, and the flame is swept downward into the combustionchamber 9, thence upward outside the baffleplate toward the stack-pipe. Theheat of combustion in the chamber 9 is sufficient to continue the distillation of fuel in the fire-pot, a merely sufiicient quantity of air being admitted through the ash-pit door to complete the combustion of the carbonaceous residue.
Now having described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-
1. In a furnace, a fuel-receptacle, acombustion-chamber immediately surrounding said receptacle, means for supplying a limited quantity of air to the fuel-receptacle, means for supplying air to and mixing the same with the gaseous products distilled from the fuel whereby said gaseous products will be burned in the combustion-chamber and continue the distillation of fuel in the receptacle therefor, and air-pipes traversing the fuel-receptacle and combustion-chamberand lying in the path of the heated gases and combustion products, substantially as shown and described.
2. In a furnace, a fuel-receptacle, a curved baflie-plate above the said receptacle and extending downward around the same, said baffleplate being adapted to direct gaseous products into thespace immediately surrounding the fuel-receptacle, means for supplying a limited quantity of air to the fuel-receptacle, and tubes along the upper edges of the said receptacle for supplying air to the gaseous products distilled from the fuel therein, whereby said gaseous products will be burned in the space immediately surrounding the receptacle and furnish heat to continue the distillation of fuel, substantially as described.
3. In a furnace, a fuel-receptacle, a combus' tion-chamber immediately surrounding the same, a bafile-plate over the fuel-receptacle and extending downward around the same for directing gaseous products therefrom into the combustion-chamber, means for supplying a limited quantity of air to the fuel-receptacle,
pipes for supplying air to the products dis tilled from the fuel whereby said products will be burned in the combustion-chamber around the fuel-receptacle and continue the distillation of fuel therein, a radiating-chamber surrounding the combustion-chamber and passages for combustion products, and pipes connecting with the radiating-chamber and traversing the path of the heated gases and combustion products, substantially as described.
In testimony whereof I hereunto aflix my signature in presence of two witnesses.
