FRANK H. PULSIFER, OF AUBURN, NEW YORK.
STEAM-BOILER FOR HEATING PURPOSES.
SPECIFICATION forming part of Letters Patent No. 302,210, dated July 15, 1884.
Application filed April 15, 1884. (No model.)
fo ai?, wiz/om it may concern,.-
Beit known that I, FRANK H. PULsIFnR, a citizen of the United States, residing at Auburn, inthe county of Cayuga and State of New York, have invented certain new and useful Improvements in Steam-Boilers for Heating Purposes, of which the following is a specification, reference being had therein to the accom panying drawings, in which- Figure l represents a vertical sectional boiler constructed in accordance with my invention, showing the passage for the products of coinbustion cut through line :c x of Fig. 3. Fig.
l 2 represents a vertical section cut thro ugh line y y of Fig. 4, showing the passage for water circulation therethrough. Fig. 3 is a top view of the second section of the boiler. Fig. 4 is a bottom View of the first section above the lire-pot. Fig. 5 is a bottom view ofthe uppermost section. Fig. 6 is a top View of the lowest or tire-pot section above the grate.
My invention relates to improvements in cast-iron sectional boilers forheatingpurposes; and the objects of 'my improvement are, rst,
-to provide a simple and inexpensive boiler,
formed of sections constructed with an inner and an outer ring connected by radial hollow arms, through which-a thorough circulation of water is effected second, to produce a magazine for coal from the walls ofthe inner ring; third, to provide the upper portion of the magazine formed by the sections of the boiler with an annular passage for the escape of gases that may be formed within the magazine. I accomplish these objects bythe construction illustrated in the accompanying drawings, iny
which similar letters refer to similar parts throughout the several views.
The boiler may have alarger or smaller number of horizontal ,sections than shown in the drawings, but I prefer to have it constructed of the following sections: a bottom section, A, forming the iire-pot of the furnace. This section rest upon a cast-iron base, B, used as the ash-pit. The latter carries the grate B', and is provided with a door, B2, for the vremoval of the ashes passing through the grate. Upon the bottom sections, A, the sections C D E are placed, one above the other. 'Ihe latter sections are each composed of an inner hollow ring, c, d, or e, and
an 'outenhollow ring, c2 d2 e?, and the rings of each section are connected by a series of hollow arms, c, cl,or c3, through which water circulates when the boiler is in operation. r:Phe inner rings, c d e, resting upon each other, form a central magazine for the reception of coal, and the outer rings, c2 d2 c2, are provided with flattened vertical tubes f, for the downward passage of the products of combustion, and intermediate openings,g, in their top and bottom walls, for the circulation of water from one section to the other. Upon the sectionE is placed the upper section or top, H, of the boiler. This section has formed in its under surface arches 7L, `to direct the products of combustion either to the hue I, leading directly into the uptake iiue K, or (according to the dampers positionjinto the descending passage f, and thence, through the lower end ofthe flue K, into said 4uptake flue, the outer 'shell of the bottom sections, A, having for this purpose four recesses, f', in its walls, to prevent any interference with the down lues, and at the same time insures the water circulation within the boiler. In the upper section, H, are formed also a series of pockets, L,to hold condensed steam or water that is returned by gravity through the steamfpipeswhile the upper sur- .face ofthe arches 7L acts as a superheater at the same time. The sections C D E are placed one upon the otherin such a manner that thehollow arms of one do not coincideycrtically with the arms of the sections immediately above it, to
cause theproducts of combustion to follow a zigzag path among said arms (dotted in Fig. 3) and have the caloric thereof thoroughly absorbed by the arms and surfaces of said sections. The central or magazine portion of the upper section, H, does not rest upon the corresponding portions of the sections E, but a small annular passage, h2, is kept between` IOO To increase the heating-surface of the boiler,
its section C is provided with a series of droptubes, IWI, screwed or cast into a boss projecting at an angle of about forty-iive degrees from the inner surface of the outer ring of said section, and within each tube is placed a lat plate, m, of iron, terminating within an inch or two of the lower end of said tube, to promote the circulation of water therein.
-The inner wall of the fire-pot section A is made vertical, but the outer Wallis made wider at the upper part, in order to increase the waterspace at the point where the heat is higher, allow the free escape of steam upward into the sections above, and thus produce a good circulation ofthe water within the boiler. The surfaces ofthe sections surrounding the waterpassage g are slightly raised, prepared and coated with cement, as usual, and all the sectioiis are united by four bolts, R, passing through lugs in the upper and lower sections, and the whole is inclosed by a jacket, N, having sliding doors I), to clean the drop-lines, when required. An opening, Q, in the side of the fire-pot is provided with a pipe extending to the outside of the jacket, through which the condition of the fire can be observed and the amount of combustion be regulated by admitting more or less air above the coal in the repot.
Having new fully described my invention, I claiml. In a cast-iron heating-furnace, the combination of the horizontal sections C D E, each section formed of concentric rings connected by hollow arms, and the inner rings located one above the other, to form a central magazine for coal, substantially as shown and described.
2. The combination of the horizontal section A, forming the fire-pot of afurnace,with horizontal section C, formed of concentric rings connected by hollow arms, and drop-tubes M, projecting inwardly over the fire-pot from the outer ring of said section C, substantially as and for'the purpose described.
8. The combination of the horizontal sections C D E with the upper section, H, provided with' pockets L and arched flues 7L, substantially as and for the purpose described.
4. The combination of horizontal sections D E, forming a portion of a central magazine for coal,with top section, H, constructed to form the upper portion ofthe magazine, and located above the section Ein such a manner as to form a horizontalpassage, h2, in the upper portion of the magazine, substantially as and for the purpose described.
5. The combination of a series of horizontal sections composed of concentric hollow rings united by hollow arms, with the fire-pot section A, having itsA upper portion wider than its lower portion, and provided with recesses f in the walls thereof, corresponding with the ues f of the upper sections` substantially as and for the purposes set forth.
In testimony whereof I affix my signature in presence cf two witnesses.
