BOlLER-FURNACE.

SPECIFICATION forming part of Letters Patent No. 730,409, dated J une 9, 1903.

Application filed January 7, 1902. Serialll'o. 88,742. (No model.)

T0 ai?, whom, it' may concern.'

Be it known that I, JACOB SMITH, a citizen of the United States, residing at Des Moines, in the county-of Polk and State of Iowa, have invented a new and useful Boiler-Furnace, of which the following is a specification.

My object is to prevent the waste of fuel and annoyances incident to the escape of soot and black smoke from boiler-furnaces by producing an enlarged combustion-chamber to increase the water-heating surface of a boiler by means of boiler-sections adapted to serve as walls of the combustion-chamber and the fuel-chamber.

Further objects are to combine boilersections with a brick Wall to aid in supporting a tubular boiler, to protect boiler-fines froinf being damaged by heat, and to feed fuel through a hopper fixed in a boiler-section in such a manner that the fuel will be. heated on top of the nre-chamber before it is dropped into the nre-chamber.

My invention consists in the construction, arrangement, and combination of parts, as hereinafterset forth,p0inted out in my claims, and illustrated in the accompanying drawings, in whichy Figure 1 is a side elevation of my furnace, partly in section, and shows the forms and relative positions of diiferentparts. Fig. 2 is a vertical transverse sectional view on the line a; m of Fig. l and shows how the main and cylinder portion of the boiler is connected with and supported by the boiler-sections that constitute the side walls of the combus' tion-chamber.

The letter-A designates the foundation upon which parallel side Walls A2 are built with brick. f

A3 is the bridge-wall.

B and B2 are flat metal plates connected by means of angle-plates B3 at their tops and bottoms to produce boiler-sections adapted to serve as side Walls for supporting a cylindrical tubular boiler C of common form to extend beyond the cylindrical boiler to serve as side wallsfor the furnace. The inner plates B2 extend down inside of the brick walls A2 to rest upon the foundation A, as shown in Fig. 2, and in combination with the brick Wall aid in supporting the tubular boiler.

The .rear ends of the plates B and B2 are connected by plates D and D2, as required to produce a boiler-section at the rear end of the combustion-chamber to communicate with the mating parallel walls and boiler-sections Y that communicate with the cylindrical boiler through a plurality of tubes F, fixed in the tops of the boiler-sections andl the sides of the cylindrical boiler, as shown in Fig. 2, or in any suitable way and in sucha manner that lime and other foreign substances in the water will be precipitated in the upright boilersections and prevent fouling the main boiler at their tops.V Angle-bars H, fixed to `the sides of the cylindrical boiler, rest upon the angle-plates B3 and serve as brackets for supporting the boiler C in the top of the large combustion-chamber that extends down to the foundation A.

f- J is the metal plate and front of the fur-v nace fixed to the front ends of the plates B and Bfiand to aboiler-section J 2, fixed to its top to communicate with the parallel upright boiler-sections. The top of the furnace or fuel-chamber is thus prevented from being damaged by intense heat to which it is subjected and also adapted for advantageously combining therewith means for supporting, beating, and feeding fuel to the furnace, as

shown in Fig. l or in any suitable way.

the kboiler-sections that serve as awall for the large combustion-chamber aids in maintain- .ing a high degree of heat in the combustionchamber to materially aid in `promoting the combustion of all valuable products of combustion liberated by fire in the fuel-chamber, as required to prevent the formation and escape of black smoke and soot, the fouling of IOO the boiler tubes, and the annoyances and waste incident to the passage of black smoke and soot through the combustion-chamber.

Having thus described the construction, purpose, and operation of my invention, its practical utility will be obvious to persons familiar with the art 'to which it pertains, and

What I claim as new, and desire to secure by Letters Patent, is-

l. In aboiler-furnace, aboiler-section made of parallel plates and the inner plates extended downward to rest upon a foundation and forward to line a furnace, in combination with a bridge-wall, a grate and a brick wall extended from the foundation to the bottom of the boiler-section, for the purposes stated.

2. In a boilerfurnace, parallel boiler-sections made of plate metal and extensions at their front ends and the extensions connected at their tops by a boiler-section provided with an aperture adapting it for combining means therewith for heating and feeding fuel into the furnace, in combination with the front wall of a fuel-chamber and a bridge-wall and a cylindrical boiler supported upon the tops of the parallel boiler-sections, for the purposes stated.

3. In a boiler-furnace parallel brick walls extended upward from a foundation-bottom, metal plates resting on the foundation and extended up inside of the brick walls, metal plates resting upon the tops of the parallel brick walls and extended parallel with the plates on the inside of said plates and connected therewith at their bottoms and tops by means of angle-plates to produce boiler-sections adapted to serve as upright walls of a combustion-chamber and to support a horizontal boiler, extensions at the front'ends of the parallel walls and a boiler-section fixed on top of said extensions and provided with an aperture and adapted for combinin g means therewith for heating and feeding fuel into the furnace, arranged and combined as shown and described for the purposes stated.

4. In a boiler-furnace parallel brick walls extended upward from a foundation-bottom metal plates resting on the foundation and extended up inside of the brick walls, metal plates resting upon the tops of the parallel brick walls vand extended parallel with the plates on the inside of said plates and connected therewith at their bottoms and tops by means of angle-plates to produce boiler-sections adapted to serve as upright walls of a combustion-chamber and to support a horizontal boiler, a bridge-wall between the front portions of the two upright parallel boiler-sections, a metal front connected with the front ends of said upright boiler-sections and a grate extending from the bridge-wall to the furnace front, arranged and combined as shown and described for the purposes stated.

5. In a boiler-furnace, a bridge-wall, two parallel upright boiler sections connected with the ends of the bridge-wall and the front wall of the furnace, a boiler-section extending horizontally rearward from the furnacefront anda hopper fixed in said horizontal boiler-section, arranged and combined to operate in the manner set forth for the purposes Stated. A

6.v A boiler-furnace comprising parallel brick walls, boiler-sections fixed on top of the parallel'walls and their inner plates extended down on the insides of the walls, a tubular boiler xed on top of the parallel boiler-sections,tubes extending from the parallel boilersections into the tubular boiler, a boiler-section connected with the rear ends of the parallel boiler-sections, extensions of the parallel walls and the parallel boiler-sections,a bridgewall, a grate, a f urnace-front and a boiler-section on top of the said extensions adapted for supporting a hopper for heat-ing and feeding fuel to the furnace, arranged and combined to operate in the manner set forth for the purposes stated.
