VILLAM H. TURNER, OF INIHANA'POL'IS, INDIANA.
WARM-AIR FURNACE.
SPECIFICATION forming part of Letters Patent No. 349,825, datei September 28, 1886.
Application flled July l1` 1885. Serial No. 17h-332. (No modi-l.)
To all whom it may concern.:
Be it known that I, XVILLIAM H. TURNER, a citizen of the United States, residing in Indianapolis, in the county of Marion and State of Indiana, have invented cert-ain new and useful Improvements in Varm-Air Furnaces, of
which the following is a specification.
My invention relates to double heaters or furnaces which take up the cold air from the floor of the apartment, or from a cold-air duct and register in said floor, into an air-chamber formed by the fire-pot or furnace proper and an outer casing, and emit the heated air above.
The objects of myimprovements are to provide a warm-ai r furnace more efficient and economical than the ones now in use, one which will. consume nearly all the smoke and soot, and one which easily can be converted into an ordinary local heating-stove. I attain these objects by the device illustrated in the aecompanying drawings, in which- Figure l is a vertical section through my warm-air furnace; Fig. 2, a horizontal section through the same on line a' a' on Fig. l; Fig. S, a horizontal section on line y y, and Fig. 4 a horizontal section on line z z.
Similar letters referto similar parts throughout the several views.
A is a cast or wrought iron conical fire-pot rising from the ash-pit chamber B in a conical shape the entire height ofthe heating apparatus and terminating in the smoke-pipe l?, the fire-pot A having its largest diameter where it rests on the ash-pit B and its smallest where itrcceives the smoke-pipe l?. The ash-pit D contains the ash-pan Z), and is provided with a door to allow of yremoving and emptying said pan, while the bottom of the ash-pit, extending out in shape of a perforated flange from the walls of the ash-pit chamber, forms the base and support of the outer sheet-iron casings, C and D, that inelose the fire-pot A. The ashpit is mounted and lrests on legs of the usual construction. In said bottom flange are openings o o, to allow the cold air from the floor to rise up into the air-chambers formed between the ash-pit B and the fire-pot A and the outer casings, C and D. The grate Gis located at the bottom of the fire-pot A, right over the ash-pit B, and constructed and operated in the usual manner.
(lv is the fuel-inlet to the fire-pot A, closed with an ordinary furnace or stove door.
Around the conical fire-pot A extends up to the top of said fire-pot the conical casing D,
made of sheet-iron, and forming with the firepot A the warm-air chamber N.
The mantle or casing C is made in two or more sheet-iron sections, each upper section being of a smaller diameter than the lower one and resting on the same by means of an. intermediate diminishing iron rim, f, provided with a flange below to fit onto the lower larger section, and with a flange above to receive the upper smaller section. The bottom section of the mantle C rests on the bottom flange of the ash-chamber B. The mantle C encircles the inner casing, D, and forms with the same the warm-air chamber M.
Both air-chambers N and M are covered at the top, where the lire-pot A connects with the smoke-pipe l) by a removable cover, F. cover F consists of two halves resting on the top flange of the mantle C, semieircular openings being eut out of each cover, so that they fit snugly around the top of the fire-pot A, both halves of the cover F being pivoted to the top flange of the mantle C at p in such a manner that they can be swung around in order to let the air pass out of the chambers M and N upward.
In the lower section of the mantle C a door, h, is located. Opposite this door h an opening, d, is left inthe inner casing or mantle, D.
rlhe apparatus operates as follows: The smoke, soot, and gases generated by the process of combustion rise in the fire-pot A. This fire-pot being of a long conical shape the entire height of the apparatus, prevents the smoke, &c., from escaping too fast into the smokepipe l?, so that nearly all of it is consumed and burned before it reaches the outlet to said smoke-pipe, thus producing more heat with the same amount of fuel than in the furnaces heretofore in use. The combustible part-icles in the smoke and soot being burned in the fire-pot, a saving of fuel is obtained, while the smoke pipes and chimneys are kept clean and their passages open. The outer surface of the fire-pot A heats the air in the chamber N, and also the inner mantle, D, which mantle D again heats the air in the outer chamber,
Said c M. By employing this inner mantle, D, and making two warmair chambers, M and N, I obtain more heating or radiating surface, and consequently better results than where only one air-chamber is used. Giving the inner mantle, D, a conical shape, the heat arising from the lire-pot A will strike against the walls of the mantle, and will much more efficiently heat the same than Where a cylindrical form for a mantle is used. By closing the top of the air-chambers M and N by means ofthe covers or lids F, and by opening the door h in the mantle C, the furnace is converted into a local heating apparatus or stove, the heat contained in the chambers M and N around the lire-pot A emanating direct through the openings d and h and radiating from the mantle C.
Having thus fully described my improvements, what I claim, and desire to secure by Letters Patent, is-
1. In a warm-air furnace, the combination, with the conical fire-pot, of the ash-pit supporting the latter, the bottom of said ash-pit being extended and formed with openings 0, the inner conical mantle, D, inclosing the lirepot and resting at its lower end upon the bottom of the ash-pit, over the openings o, and the external casing inclosing the mantle D, substantially as set forth.
2. In a warm-air furnace, the combination, with the conical fire-pot, of the ash-pit supporting the latter, the bottom of said ash-pit being extended and formed with openings o, the conical mantle D, resting on the bottom yof the ash-pit at its lower end, over the openings o, and having the opening d, the outer casing, C, having an opening, and the door h, for closing said opening, substantially as set forth.
In testimony whereof I have signed my name to this specication in the presence of two subscribing witnesses.
