Description

Patented March 1, 1904.
PATENT OEEICE.
EPHRAIEM OHAQUETTE, OF NEW ROCHELLE, NEW YORK.
SMOKELESS BO|LER.
SPECIFICATION forming part of Letters Patent No. 753,360, dated March l, 1904. Application lell .Tune 4, 1903. Serial No. 160,010. (No model.)
To a/ZZ whom it Wha/'y concern: Be it known thatI, EPBRAIEM CHAQUETTE, a citizen of the United States, anda resident of New Rochelle, Westchester county, State of powerful as a steam-producer and which also by reason of its construction consumes practically all the smoke generated in the furnaces,l
letting little, if any, visible products of combustion escape. To this end I construct my improved boiler with two fire-pots so arranged that the smoke from each passes over the fire contained in the other, thus completing the combustion of the fuel, and I arrange the water tubes and chambers over the two lire-pots or furnaces in such a way that the heated air arising from both the furnaces mingles at the entrance to the boiler-section and after passing under and through said secr tion escapes by a common flue. In my improved boiler the two fire-pots are intended to be used alternately in the sense that after the furnaceis once started the fresh fire of one {ire-pot passes over the old fire in the other fire-pot until the old fire needs freshening, when the conditions VVare reversed.
As the exterior of the furnace will be readily understood from the description of the interior, I have shown in the accompanying .drawings only sectional views to illustrate the path o'f the heat, smoke, and other products of combustion through the furnace.
Figure I is a cross-section taken just behind the front wall of the apparatus. Fig. Q'is a longitudinal section.
Same letters indicate similar parts in the dierent drawings.
`A B are two fire-pots arranged side' by side and extending practically the full length lof the furnace, provided with the usual grates C over the ash-pits D E. The 'two lire-pots are separated by a'water-.leg H, which serves as a dividing-wall between them and which, eX- tends from the front nearly to the rear. This water-leg communicates with a horizontal boiler-sections, which serves as a roof for the fire-pots. At the forward end of each furnace is an upturned passage or flue F G. each of .which iiues communicates with its fire-pot by an opening f g, which is closed when required by a damper it. l These iiues are closed at the top by a horizontal-partition I, which stretches across the front of the boiler and from which there is communication with the left half of the' boiler-section through the opening I', but not with the right half, the boiler-section being divided longitudinally by the partition j. The object of this construction is to compel the hot air which enters by either of the flues F Gr to follow the same course in seeking exit from the furnace.
The boiler-section consists of a hollow ioor K, lled with water, and hollow side walls LL, also lled with water and connected with each other by the tubes Z Z, reaching horizontally across the boiler-section and passing through the partition j. The rear wall of the boilersection O is also hollow and filled with water and in communication with the sides and floor.
M is the chimney or iiue through which the hot air goes oifafter passing through the boiler-section from front to rear through theV left-hand section, around the partition j, which is spaced from the rear wall for that purpose, and thence forward through the righthand half of the boiler. y N is the dome, through which steam enters by suitable pipes from the side walls L L.
By reason of the fact that the left half of the boiler section is constantly open to the flues F Gr, but closed to the iiue M, while the other half is open to"theflue M while closed to the iiues F G, the circulation of air through the boiler-section is always in the same direction, whereas by means of a damper fr the circulation through the re-pots may be turned lfrom one direction to the other as occasion requires. It will thus be seen that the products of combustion always travel four times the length of the structure before passing off into the Hue M and that the water in the boiler receives heat from an enormous surfacenamely, looth sides of the water-leg, both surfaces of the iioor, the side walls, the end walls,
IOO
and the horizontal pipes connecting the side walls.
I claim- A combined boiler and furnace comprising two lire-pots arranged side by side, a waterleg serving as the dividing-wall between said {ire-pots and spaced from the rear wall of the furnace so as to afford communication between the lire-pots, a boiler-section communicating with the water -leg and forming the roof of the fire-pots, water tubes located above said section, a longitudinal partition extending from the front wall midway of the water-tubes
