COMBINATION COAL AND WOOD HEATING-STOVE To all whom-it may concern:
'Be it known that I, 'LmconnTEwARo, a citizen of the United States, residing at Ralston, in the county of DouglasanrLState of Nebraska, have invented-certain new and useful Improvements in a Combination Coal and lVood Heating-Stove, of Which the following is a specification. r v
The object sought by me in the invention of the improved stove hereinafter described is to provide a stove from which increased heat is obtained from a decreased quantity of fuel and in which either wood orcoal can be used as a fuel.
I accomplish my object by the construction shown in the accompanying drawings, in which' Figure l is a longitudinal sectional elevaf tion of the stove, the base, fire pot and drum 1 broken away to show the interior arrange 'mcnt; Fig. 2 is a top view of the fire pot,
rear of the base of the stove,
grates, and. a flange or projection at the rear of the fire pot with openings therein, and Fig. 3 is a sectional view of the fire pot, the a casting seated therein and a segmental opening for the passage of hot air. 1
Similar letters referto similar parts in the several views.
A'is a fire pot cast in an inverted conical 4 shape to assist in radiating heat to the floor.
B shows a flange, projecting rearward from the fire pot, the same being provided with openings 6 b Said fire pot flange is also provided underneath its edge with a groove 6.
C is a casting spaced from the rear of the fire pot. D is the base of the stove, D D are the grates therein and d is a segmental opening into said base. Said casting C is seated in the top edge of said base, as shown in Fig. 1, its top edge being held in said groove I). Said casting formsa passage at the rear of said fire pot through which preheated air draws through openings 6 b passes downward and thence through said segmental opening ti into the base of the stove from which base it is drawn up through the rates into the fuel. The sheet iron body of the stove is, preferably, joined to the top of the fire pot, as shown in Fig. 1 at e. F is a casting which forms an inner wall of a draft passage through which cold air entering the stove at draft F Specification of Iletters Patent. Application filed June 17, 1910. Serial No. 567,440.
Patented May 23, .1911.
passes to the rear of the stove, part through ports f f into the combustion chamber above the fire pot, the balance through said openings Z2 Z2. into the pre-heated air passage formed by casting G and thence down through said segmental opening d into the base of the stove. The (sIp of casting F is to carry the col air entering the stove at said draft F around the stove the longest possible circuit so that it will be heated to the highest degree possible before it is admitted into the combustion chamber. Said casting F is seated in the upper edge of the fire pot and is usually coinposed of two or more sections; it is preferably corrugated, except at the edges where it joins the sheet iron bod and the fire pot of the stove. The upper edge of said casting lies fiat against said sheet iron body. The purpose in casting it corrugated is to secure greater strength and heating surface.
H is an incurve extending horizontally around casting F. The rear section of said casting is provided with a seat J in said inciirve H to support a bathe plate K; The air admitted through draft F passes through said incurved draft passage and becomes highly heated in passing to the rear of the stove, the larger part passing thence through a plurality of ports 7* f in the lower part of castin F into the combustion chamber under batle plate K where it is forced to mingle'with and burn the gases and smoke coked out of the fuel, while the smaller part passes. down through openings Z) L as shown in Figs. 1 and 2, into and through the hot air passage formed by casting O and through segmental opening d,
as shown in Figs. 1 and 3, into base D, much of it passing thence up through grates D D to start and keep up the coking and gas making process. Casting F is kept at'a high temperature by means of a hot blast from the rear of the stove, and the temperature of the air while passin through it continues to increase. The v0 ume of air passing through said draft passage is j greatly expanded by its rise in temperature and I rushes into the combustion chamber with great force. Bymeans of the bafiie plate K this pre-heated air is deflected toward the fire and forced to mingle with the combustible smoke and gases arising from the fuel. That part of the pie-heated ail:
passing downward through the base is only 'suflicient to keep the fire al ve ahd keep up the coking and gas making prode'ss.
What I claim and desire to ,setnre by Letters Patent, is,-
The combination in a wood an 'cosl h ing stove, of a base having segmenta o ening in the rear part of'the' too, a fire pot of inverted frusto conial shape; dup icate grates therein, e horizontal hangs on the top edge of the rear o the fire pot provided with a plurality of n ngs a d w th a curved groove nndernea? the edge t of; a curved casting seated, in the side of the fire pot and on sald base ou -si e sa d segmental opening its top end engaging with said groove, the central art of sa d casti g being spaced from se-i. fire pot fo therewith a hot air passe e, in sheet ir body, a corrugated inonrve; oastin seated onthe fire pot and admit door to r'eior;
said ineurve in said casting and the stove I body formin a passage for'theair entering said dra t door the ports above the fire pot through the rear part of the incurved "casting forming outlets from said passage intoxthe combustion chamber through which a part the pre heated air from said incurved passage ss e s' into the combustion while t e balance is drawn down the rear hot air passage formed by said ed xcast ng into aid be P p into the uel, and? Plate to force the P heated air from ports to-mingle with and burn the gases and smoke coked out of the fuel, substantially as shown and described.
. In testimony whereof-I aflix my signature in presence of two witnesses.
