SMOKE-BURNING FIRE-BOX FOR STOVES, FURNACES, AND BOILERS- Specification of Letters Patent.
Patented Jan. 22, 1907.
Applicauion filed November 14, 1905. Serial No. 287,337.
To aZZ whom it may concern.-
Be it known that I, JAMES J. DOGKERY, a citizen of the United States, and a resident of St. Louis, Missouri, have invented certain new and, useful Improvements in Smoke- Burning Fire-Boxes for Stoves, Furnaces, and Boilers, of which the following is a specification.
This invention relates to improvements in a smoke-burning fire-box for stoves, furnaces, and boilers; and it consists in the novel arrangement, construction, and combination of parts, as will be fully hereinafter described and claimed.
The object of my invention is to construct a fire-box located .in either a furnace, stove, or boiler provided with hollow blocks providing a passage from the fire-box to the chimney.
A further object of my invention is to provide a fire-box composed of a plurality of hollow blocks and arranged to be fitted to the inner circumference of the casing, the said blocks providing passages through which the heat passes, and suitable draftopenings located at the top to permit air to pass downwardly upon the fire-bed and cause the smoke to be superheated and burned before passing out through the passages formed in the hollow blocks.
In the drawings, Figure 1 is a vertical sectional view of a furnace, showing my improved fire-box and taken on the line 1 1 of Fig. 3. Fig. 2 is a vertical sectional View taken on the line 2 2 of Fig. 4. Fig. 3 is a horizontal sectional view taken on line 3 3 of Fig. 1. Fig. 4 is a horizontal sectional view taken on the line 4 4 of Fig. 1. Fig. 5 is a horizontal sectional view taken on the line 5 .5 of Fig. 1. Fig. 6 is 'a detail perspective rying out my invention. Fig. 7 is a perspective view of the same block in different position.
Referring to the drawings in detail, 8 indicates the casing of an ordinary furnace provided with a top 9 and the usual grate-bars 10 and ash-pit 11. Around the grate-bars and secured to the casing is abracket 12, on which is built the fire-box 13. The fire-box 13 is composed of a plurality of blocks 14, composed of fire-clay and of a height sufficient to accommodate the usual amount of fuel placed in a furnace, stove, or boiler. The upper edge of each block 14 is provided with an inclined surface 15, which establishes communication between the interior of the fire-box and the passages 16, through which the heat circulates to the upper portion of the furnace.
The passages 16 referred to are formed in the blocks 17, whichare composed of fire clay and constructed of two sides 18 and 19 and an edge wall 20. The upper surface of the edge wall 20 is provided with an integrallug 21, and the lower end of the edge wall 20 is provided with a recess 22. The sides 18 and 19 are provided with grooves 23, running longitudinally with the block, and are for the purpose of adjusting the width of the said block when placing the same into various sizes of casings in building up a fire-box. This adjustment is accomplished by chipping off the edges of said blocks in alinement with the grooves 23. The blocks are also provided with similar grooves 24, running horizontally and in the center of the block, and. are also for the purpose of adjusting the height of the blocks by breaking the same in alinement with the grooves and chipping off sufficient to shorten the same. The blocks 17 are made, as shown in Figs. 6 and 7, of two parts. the free ends contacting together, forming the passage-way 16, the formation of which will be seen in Fig. 3. The walls of the blocks are of sufficient thickness to prevent the excessive heat passing from the fireboX up through the passages from overheating the shell or casing of the furnace.
In building up the fire-box with the blocks 17 the lower blocks are placed upon the upper surface of the blocks 14, the passageways formed by said blocks, together with the inclined surface 15 of the blocks 14, providing a free passage for the draft and heat to pass upwardly. The second series of blocks are built upon the blocks just described, their passage-ways communicating with the lower, and so on. The blocks are set one upon the other to any height desired, depending upon the location of the fuel-door in the casing. The blocks when set are interlocked by means of the recesses 22 fitting over the lugs 21, except within the lower series of blocks, where the recess 22 will provide a horizontal passage around the entire circumference and permit the heat to circulate from one passage into the other. The lugs 21 on the uppermost series of blocks act as supports for the top 25, which is preferably constructed of slabs of fire-clay, the meeting edges of said slabs so constructed to interlock to provide a seal-joint. From the outer surface of the casing and leading through the top of the slabs 25 are pipes 26, which provide a draft-passage into the top of the fire-box, and the draft through said passage being regulated by ordinary rotary dampers 27.
28 represents the fuel-door, which is located immediately below the slabs 25 and through which the fuel is admitted into the fire-box. The door 28 is also provided with an air-damper 29, through which air is admitted into the fire-box, and the ash-pit 11 is also provided with an air-damper 30, through which air is admitted and only used when building the first fire.
The operation of my invention is as follows: After the shell of an ordinary furnace,
stove, or boiler has been suitably lined with the blocks of fire-clay, as formerly described, the fire is first kindled upon the grates, the damper in the smoke-pipes opened, and the air-passage 30 in the ash-pit opened, the draft from the smoke-pipe having direct access upon the fire through the passages 16. Then the material in the fire-box is properly ignited, fuel is admitted or placed within the fire-box through the fuel-door 28. The damper 30 in the ash-pit is then closed. Air is admitted through the pipes 26 and also through the fuel-door 28, which will cause the smoke and materials of combustion to pass downwardly over the top of the fire and pass upwardly through the passages 16, whichaction has a tendency to burn or consume all particles of combustion, and thus dispense with the greater portion of the smoke.
In placing my invention into a stove or furnace with a conicalshaped casing I construct my blocks in the form of a keystone, so that the entire body when properly connected will retain its position by its own sup )ort.
1 Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is
1. A smoke-burning fire-box composed of blocks having a tapered upper edge forming the base of the fire-box, a plurality of hollow blocks built upon the blocks forming the base and arranged together forming direct passage-ways from the top to the bottom the tapered upper edge establishing communication between the passage-ways and the interior of the fire-box, and a cover located upon the top of the fireboX, substantially as specified.
2. A device of the class described, comprising a casing, a plurality of fireproof blocks located within said casing, said blocks so constructed that when joined together passageways are formed, establishing communication between the fire-box and the upper portion of the casing, an interlocking device formed on the blocks to support one block upon the cover, and a cover inclosing the space between the blocks forming the fire-box, substantially as specified.
3. A smoke-burning firebox comprising a plurality of fireproof blocks arranged together to form the fire-box, the upper ends being beveled, a plurality of blocks provided with channels built upon the blocks forming the fire-box, said blocks composed of two sections adapted to form a passage when joined together, the beveled ends establishing communication between the passages and interior of the firebox, lugs formed on the upper ends of the blocks, and recesses formed on the lower ends of said blocks, said lugs and recesses acting as a locking means to support said blocks in position, a slab located upon the top of said blocks and. held inposition by the lugs on the upper blocks, pipes passing downwardly through the slab acting as air-passages from theatmosphere to the fire-box, substantially as specified.
4. A device of the class described comprising a fire-box composed of solid and hollow fireproof blocks, a cover formed upon the top of the fire-box, the hollow blocks when joined together form passages through which the heat and draft passes to the smoke-stack, suitable draft-passages leading to the top of the fire-box supplying air to mix with the particles of combustion, substantially as specified.
In testimony whereof I have signed my name to this specification in presence of two subscribing witnesses.
JAMES J. DOCKERY.
