EBPECIFICATION forming part of Letters Patent No. 330,885, dated November 24, 1885.
Application filed December 29, 1884. Serial No. 151,514. (No model.)
To all whom it may concern:
Be it known that we, CHARLES W. FOWLER and ANTON O. NEPIL, of Des Moines, in the county of Polk and State of Iowa, have in vented an Improved Boiler- Furnace, of which the following is a specification.
Our object is to reduce the cost of constructing, combining, and maintaining in order all the parts of a boiler-furnace; to prevent the annoyances and loss incident to the generation and escape of gas, smoke, and soot; to increase the water-heating surface; to diminish the minimum of fuel required, and to augment the maximum of heat and power produced from any given quantity of fuel.
Heretofore an annular boiler-section having vertical tubes in its upper portion and adapted to be used as a fire chamber has been inclosed in a second annular boiler-section, and athird annular boiler-section placed over the two concentric sections, and a fuel-magazine extended through the top section and into the inner lower section, and the three sections connected by means of tubes to produce a circulation of water and steam, and a grate and wall combined with the three boiler-sections thus constructed and connected to produce a boilerfurnace; but in no instance have two separate and distinct boiler-sections been formed as contemplated by our invention,which consists in the construction and combination of two cylindrical boiler-sections of peculiar shape that are specially adapted to produce, in combination with each other and afuel-magazine, three distinct combustion chambers, within which three chambers the products of combustion will be more efiectually utilized than heretofore, and by means of which chambers an increased area of water-heating surface is pro duced without increasing the size and cost of the complete boiler and furnace.
Figure 1 of our accompanying drawings is a vertical section of our boiler-furnace. Fig. 2 is a transverse section at the point of elevation indicated by dotted line X X in Fig. 1.
Jointly considered these figures clearly illustrate the construction and operation of our complete invention.
A represents the outsidewall of the furnace, which may be made of brick or plate metal, and vary in size as desired.
13 is the lower section of our boiler, supported upon the furnace-wall. It is composed of a cylinder, 13*, made of boiler-iron, and three concentric plates, 13*, B, and 13", that vary in diameter. These concentric plates are con nected by means of ring-shaped plates 0, O, and 0 that have flanged edges that overlap the plates, and can be readily riveted fast in a common way to produce afire-box, No. l, and an ash-box in the lower portion, and a combustion-chamber, No. 2, in its upper portion. A series of open-ended tubes, D, are fixed to the ring shaped plates to extend through the boiler-section and double wall of the firebox thus formed. A second series of open-ended tubes, D extend through the upper portion of the same boiler-section to establish communication between the chambers Nos. 1 and 2 and a chamber, No. 3, at the top of the tubes and the space outside of the boiler.
F is the upper boiler-section, composed of a cylinder-plate, G, a short concentric plate, G, a bottom, H, a top, J, and an open-ended cylinder, K, that is fixed in the center of the top and bottom plates to form an opening for the introduction of a fuel-magazine, L,that extends through the upper portion, F, of the boiler and down into the combustionchamberNo. 2, so that its lower open end will terminate near the fire-chamber No. 1, as shown in Fig. 1. This magazine is fastened to the upper boilersection by means of screw-bolts or in any suitable way, so that it will be detachably connected and suspended within the boiler.
N N are tubes attached to the upper and lower boiler-sections to conduct water from the upper to the lower and to circulate water and steam in the complete boiler.
R represents a grate that may vary in form as desired, supported in the lower end of the complete boiler by means of bars fixed to the boiler or in any suitable way.
S is an ash-box and air-chamber fixedto the lower end of the boiler and under the grate to receive the ash es that fall through the grate and to supply air for the fire above the grate.
T is a soot-chamber on the outside of the plate B and the ash-box, into which ashes, soot, or any solid matter that may be drawn through the tubes D and D will drop, and from whence it can be readily removed through a door on the outside furnace-wall.
In the practical operation of our boiler-furnace thus constructed the fire is started upon the grate, which is accessible through doors in the outside walls and the lower boiler-section, and fuel is then supplied to the fire through the removable top of the suspended'fuel-magazine in a common way. The products of combustion will rise and fill the annular chamber that extends above the fire-chamber, and from thence press downward to pass over the burning fuel to aid combustion, and up through the short inner series of tubes, the annular chamber No. 3 at their top ends, and from thence downward through the outer series of tubes into the annular space that exists between the boiler and the outside wall, in which annular space they will rise to escapethrougha smokeflue or chimney connected with the upper portion of the outside wall. The boiler-surface, consisting of the walls of the chambers Nos. 1 and 2, the series of tubes D and D", and the annular chamber No. 3 at their top ends, the tubes N, and the outside surface of the vertical portion of the entire boiler, is thus constantly enveloped by the products of combustion, and absorbs substantially all the heat that is generated in the furnace, and utilizes the heat in producing steam and power. Cold air is admitted through an automatic register into the ash-box under the grate, where it becomes and 3, and to operate in the manner set forth,
for the purposes specified.
2. The combination of the boiler -'section composed of concentric walls B B B, and E the ring-shaped plates 0 O 0 and the boilersection composed of the concentric plates G and G, a bottom, H, a top, J, and an open- 5 ended cylinder, K, substantially as shown and described, for the purposes stated.
