I MAGAZINE HEAT-llQG-STOVE.

T in whom it may concern.-

Be' it known that I, ELLSWORTH DAvrn MARSHALL, a citizen of the United States of America, and a resident of S dney, county of 7 State of Ohio, have invented certain Shelby, new and useful Improvements in Magazine Heating-Stoves, of which the following is a full and clear specification ,reference being had drawings, in which- Figure 1 is a pers ective view of a heatingstove provided wit my improvements, the combustion chamber of the stove being broken away to show the jacket of the air chamber or magazine ;'Fig. 2, a vertical transverse section of the same; vertical sectionflon the line 3 3 and Fig. 4 a horizontal section on the line 4 4.

The object of this invention is to provide a eral views.

[Referring to thedrawings by reference characters, the letter A designates the main wall of the combustion-chamber, provided with a door a and a circumferential flange a, of the usual construction. A removable lid of fits into an o ening in the fuel-chute H,

which chute inc ines backwardly and downwardly and is connected to the upper end of an upward-tapering munication between the chute H and the fuel-magazine being ada ted to be cut ofi by a-substantially gas-tight valve G, which valve is operated by a rod g.

I The cylinder B surrounds the magazine 0 and in connection therewith and the connecting-heads D and E forms an air-chamber which entirely surrounds the magazine. The

" lower head E is flanged at e and the upper head D is flanged at d for the attachment of the ends of the magazine and cylinder B. The heads D and E are suitably su ported within the combustion-chamber, an the air-chamber formed between them isv divided verti- Speeification of Letters Patent.

cally by means of partitions F, which extend from the lower head E to near the upper head D and are located at diametrically opposite sides of the fuel-magazine.

The magazine'and air-chamber are located eccentrically with reference to the cylindrioal stove-body-that is, at or near the rear wallthereof. wAn air-inlet a (controlled by a suitable register a is formed in the fire-pot section a and is in communication with ahole e, formed in the lower head E atthe rear. A series of holes 6 are formed in the lower head in front of'the partitions F for the escape of the air into the combustion-chamber.

It will be observed that while a fire is burning in the stove and the valve of is open the air-supply is drawn in through the inlets e a at Q the bottom of the rear section of the air-chamber and thence is compelled to the upper ends of the partitions through the outlet-openings e In starting the fire the draft may be taken direct, as usual, through the ash-door and up through the grate, andafter the fire is started the draft will'be sufficient to draw the air in F and down through the magazine in the manner set forth. i

It will be observed that the productsof combustion are free to pass up and around the side and top of the air-magazine and out through the outlet at? It will be observed that by taking the air in at the rear lower end of the magazine and compelling it to pass upward and then down- 'ward before it meets the flames not only insures that the air will be heated to a considerable degree, but also that the temperature of the fuel-magazine will be kept down to a minimum, sible the generation of explosive gas in the fuel-chamber and permitting the use of soft coal without danger of explosions. It will be observed also that by reason of the arrangement of the magazine and the air-jacket and outlets e the heated air will be delivered directly over and down into the hottest part of the fire, so that complete combustion-of the generated gases'will ensue and danger of explosions from accumulated gases be thereby avoided. Thus setting back the magazine and the air-chamber has the further advantage that an extended inlet conduit or pipe i s rendered unnecessary, and ample space is provided in front for examining v thereby avoiding as much as pos.

little to the cost of the stove and will render it unnecessary to make any material changes in the construction of the stove.

It will be apparent to those skilled in the art that various mechanical embodiments of the invention are possible, and I therefore do not wish to be limited to the exact arrange ment and construction shown.

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

1. In combination with a heating-stove, a fuel-magazine supported in the combustionchamber thereof near the rear wall of the stove, a downdraft air chamber surrounding said fuel-magazine, partitions extending upward to near the top of the air-chamber so as to divide the air-chamber into a rear and a front section, the lower end of the front section being over the center of the firepot, an air-inlet leading into the lower end of the rear section and an air-outlet leading from the lower end of the front section of the airchamber down into the fire-pot.

2. In combination with a heating-stove provided with a fuel-magazine and means whereby said magazine may be charged from the top, means closing the top of said magazine, an air-chamber surrounding the fuelmagazine substantially its full length and having partitions extending upward to near the top of the air-chamber thereby dividing the air-chamber into a rear and a front section, an air-inlet leading into the lower end of the rear section and an air-outlet leading from the lower end of the front section of the air-chamber down into the fire-pot.
