HEATING s'rovn on. summon.
.7 0 all w ham it may ounce rm." l
Be it known that I, FREDERICK DJ (look, a citizen of the United States, and a resident of Blairsville, in the county of Indiana and State of Pennsylvania. have invented a new and Improved Heating Stove or Furnace, of which the following is a description. i
Sl OVGS and furnaces particularlyhouse stoves and furnaces aremade ordinarily 0:! cast or of sheet metal. The cast metal is more rigid and holds its shape when ln'ought to a red heat but it is more porous than sheet metal, thus not so eflicient in transmitting the heat and the fire pot is liable to crack when unevenly heated. To overcome the tendency to crack, the fire pots are made either heavy or ribbed or they are lined with fire brick at the fire zone and these features when employed diminish heat radiation. Sheet metal on the other hand is more fiexible than the cast metal and this quality rapidly increased as the material is brought to a red heat for which reason it is necessary when sheet metal is used for the lire pot to line the sheet metal at the fire pot with fire brick. The fire brick diminishes radiation and also, if the firing is such as. to produce a high heat there is danger of the shell buckling or bulging just above the fire line. Sheet metal he. an advantage that it may be used much thinner than cast metal. and for this reason together with its greater density it is much more efiicient iii-transmitting heat. i
The prime object of my invention is to so combine the sheet metal and cast'metal as to overcome or minimize the defects of these metals as used in the usual ways and pro-- duce a stove possessing the meritorious attributes oi both metals.
The stated object is attained in the novel:

Fig. 3is a perspectiveview of the fire pot in its preferred form. V
I11 carrying out my invention in accordance with the illustrated example a cast metal base 10 is provided of any suitable shape it having an, ash door 11 and any approved form ot' grate and appurtenances, a rate, 12, being here conventionally shown. pen the topioit' cast base 10 I provide a cast metal fire pot 13 made in one piece and advantageously a separate casting from the base. The upper portion of the body of the stove or heater constituting the "radiating chamber thereof is made in the form oi? a sheet metal shell 1 1 which has a closed top 15 of any approved construction and an open lower end, said shell being provided with a fire door 16 as well as an opening for receiving a stove pipe 17. The shell llfis passed downward over the fire pot 13 and extends about the same with a snug fit. The loWer edge of the shell 14 is supported on the base 10, the shellextending preferably at the inside of an upwardly projecting annular flange 18 of said base to which the shell is fastened by suitable rivets or bolts indicated at 19.
With thedescribed construction the sheet metal shell fitting snugly about the cast is used, radiation being in fact promoted by my arrangement, and also, a much thinner cast metal fire box can be used because closely jacketed with the sheet metal.
Thefire pot 13, it will be observed, is given a shape to be somewhat higher on that side opposite the fire door or charging door 16, the purpose being to guard against the piling of fuel over the top of the fire pot against the thin shell 14:, the tendency in firing being to pile the charge somewhat hi her atthe far side from the fire door.
would state in conclusion that while the illustrated example constitutes a practical. embodiment of my invention, I do not limit Cir myself strictly to the mechanical details herein illustrated, since manifestly the same can'be considerably varied without 'depar. hire from the spirit of the invention as defined in the appended claims.
Having thus described my invention, I claim: v
1. A stove or heater of the class described, including a cast metal base, a cast metal fire pot thereon, and a sheet metal shell forming the upper portion of the structure, said shell being open at its lower end and, fitting snugly about said firepot.
.2. A stove or heater of the class described including a cast metal base, a separate cast metal fire pot above .and resting on said base, and a sheet metal shell forming the upper portion of the structure, said shell being open at its lower end and fitting snugly about said fire pot, the lower end of the shell being fastened to said base.
. 3. A stove or heater of the class described including a cast metalbase, a grate thereon, a separate cast metal fire pot above and resting on said base outward of the grate, said base having an upstanding flange outside of the lower end of said fire pot, and a sheet metal shell forming the upper portion of the structure, said shell being open at its lower end and fitting snugly about said fire pot between the same and said flange and being 'fastened to said flange.
4. A stove or heater including a cast metal fire pot, and a sheet metal shell forming the upper portion of the structure, said shell being open at its lower end and fitting as a jacket snugly about said fire pot.
A stove or heater of the class described, including a base, a cast metal fire pot thereon, and a sheet metal shell extending about said cast metal fire pot and closely fitting the same, to prevent unequal heating and cooling of said cast metal fire pot.
(5. A stove, including a cast metal fire pot, and a sheet metal shell extending about said cast metal fire pot and closely fitting the same.
