HENRY SIEBEN, OF CHICAGO, ILLINOIS.
STEAM-BOILER FURNACE.
SPECIFICATION forming part of Letters Patent No. 507,938, dated October 31, 1893. Application filed March 6, 1893. Serial No. 464,756. (No model.)
To all whom it may concern.-
Be it known that I, HENRY SIEBEN, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Steam-Boiler Furnaces; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.
My invention relates to improvements in steam boiler furnaces, the object being to provide a novel construction of the same, whereby the fuel will be completely consumed and the feed water of the boiler heated before being forced into the boiler.
The invention consists in the novel construction and combination of parts hereinafter fully described andclaimed.
- In the accompanying drawings; Figure 1 is a longitudinal sectional elevation of a steam boiler furnace constructed according to my invention. Fig. 2 is a horizontal section of the same on the line as, m, Fig.1. Fig. 3 is a cross section on the line yy Fig, 1. Fig. 4 is a detail sectional view of a modified construction of bridge wall. Fig. 5 is a detail perspective view of one of the perforated heads connected with the flues in the bridge wall.
In the said drawings the reference numeral 1 designates an ordinary steam boiler provided with a steam dome 2.
The numeral 3 denotes the furnace walls, constructed of brick work in the usual manner being provided with a grate 4, ash pit 5, fire chamber 6, and door 7. At the rear of the tire chamber is a bridge wall 8, provided with a number of fiues 9, having openings 10 at their lower ends leading to the ash pit. There are also similar flues in the sides of the furnace just in rear of the bridge wall. These fines at their upper ends communicate with heads or hoods 12, provided with a number of perforations 13.1
Located in the combustion chamber 14:, at each end thereof are two transverse pipes 15, 15, connected together at their ends by longitudinal pipes 16, 16. These cross pipes 15 are provided with pipes 17 leading toapump or other device connected with the feed water supply, and the rear pipe 15 is connected with the boiler by pipe 18, The pipes 16 are supported upon the walls 19, while the cross pipes serve to support the brick work upon which the boiler rests. A piece of tiling 20 having a groove on its under side and flat upon its upper side fits over the pipes 15, and upon these pieces of tiling the brick work is built.
The reference numeral 21 denotes a steam pipe leading from the steam dome to the fire chamber and is provided with a nozzle 23.
The operation will be readily understood. When a fire is made in the fire chamber the air in the ash pit will become highly heated and will escape through the flues in the bridge wall and will mingle with and pass to the combustion chamber with theunconsumed products of combustion and becoming ignited in said chamber will give forth an intense.
heat, not only heating the water in the boiler, but also heating the feed water in the pipes 15 and 16.
The steam jet pipe 21, may or may not be employed as desired.
Having thus described my invention, what I claim is' r In 'a steam boiler furnace having a fire chamber, a grate, an ash pit and 'a'combustion chamber, the combination with the bridge wall having a series of vertical fines communicating with the ash pit below the grate and with the combustion chamber and-provided with perforated hoods at the upper ends, of the side walls having horizontal and vertical fines communicating with the ash pit and with'the combustion chamber in rear of the bridge wall and provided with perforated -hoods so located as to discharge or force heated air from the ash pit, across the path of the products of combustion as they pass to,
the combustion chamber, substantially as described.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
HENRY SIEBEN.
Witnesses:
R. BARNITT, MATTHEW WAGNER.
