T a/ZZ whom/it may conserve.'

Be itvknown that I, JACOB M. U'rz, a citizen 'of the United States, residing at Duff, in f the county of Dubois and State of Indiana,

tion is better understood, the same consists t in certain novel features of construction, as

hereinafter fully described and claimed.

`In vthe accompanying drawings, forming a part lof this specification, and in which correspondingr parts are denoted by like designating characters, is illustrated the preferred form of embodiment of the invention capabley of carryingfthe same into practical operation.

In thedrawings, Figure 1 is a longitudinal vertical section. Fig. 2 is a horizontal section on the line 2 2 of Fig. 1. Fig. 3 is a vertical Asection on the line 3 3 of Fig. 2.

The improved device comprises an outer I y shell or drum 10, preferably of sheet metal of V requisite quality and strength and closed'at the upperk end by' a top member 11, prefer4 ably ofv cast-iron, and closed at the lower end by a bottom,member' 12, also of cast-iron,

the bottom member having an ash-pit 13 disposed below its central portion.

Within the outer shell .10 an inner shell 14 is arranged' and spaced from the outer shell and extendingbetween the top member 11 and bottom member 12, with the ash-pit 13 with a smoke discharge or outlet 17.

Connecting the outer and inner shells adj a- "cent to the smoke-outlet 17 is a artition 18,

extending' the whole distance etween the vtop member 11 and bottom member 12.

A smoke-aperture 19 is formed in the inner shell'14 adjacent to the partition 18 and at the opposite side of the same from the dischargevmember 17. A

shells 10 and J14 area lurality of .partitions 21 of less length than t Ae shells and arranged with the ends alternately spaced from the top and bottom members so that the 'smoke fand `other products of the 'combustion are caused to follow a zigzag course from the aperture 19 to the final ldisch-arge t17 Any required number of the partitions 21- may be employed, and for the vpurp'ose of illustration three are shown, two with the passages beneath them yand one with the passage above it, so that the ysmoke and 'other products vof the combustion will pass downward from the aperture 19, beneath thejfirst partition 21, thence over the next partition, thence beneath the third partition, 'and thence out through the discharge .19. By this means the smoke and 'other matter is 'caused to traverse upwardly and downwardly between the shells in its passage around them or in a zigzag course-,'the nu'mber of the lcourses depending on the number `of the partitions 21. y l

A direct-draft damper 22 will'preferably be arranged in the inner shell 14 adjacent to the main outlet 17 for use in iirst starting the l forming closures to the inner ends of the chambers which come above the linings 41 of one thickness only of the sheet metal of which the shells are constructed. By this arrangement the area within the chamber is subjected to heat radiated into the same from the fire within the inner shell through the comparatively thin end closures formed by the wall of the inner shell and also from the smoke-flame and other products of the combustion passing through the space between the shell. The air in the chamber is thus very ra idly and highly heated and eX- pelled therefiom and re laced by the cooler air from the outside, anni) thus creates a rapid and continuous circulation of the air through 'the chamber and rapidly warming the air in employed, and they will be arranged where the greatest heat occurs, or where lof IIC

they will be subjected most directly to the currents of hot smoke-flame and other products of the combustion.

The grate employed in the improved heater is formed in two plates or frames 24 25, supported for rotation at 26 upon a hinge 27 and provided with handles 28 29 extending beyond the outer line ofthe stove structure.

The grate-frames are provided with radiaing-apertures, as shown in Fig. 2, and by vibrating the two grate members in opposite directions the ashes andclinkers will be discharged into the ash-pit: 13.

The ashepit is about Iequal in width to the inner shell 14, and the outer'shell 1() overhangs theyash-pit at-the sides, as shown in Fig. 3, and the overhanging portions are provided with cleanout apertures 30 31, having detachable closures 32 33.

The entrance to the ash-pit is provided with a door 35, hinged at 42, having a plurality of draft-apertures, and with aclosure 37, hinged at 88 to the door 35. Connected to swing upon the door 35 is anut 39, through Whicha screw operates, the. screw being mounted 'torotate 'in the, door. By this means' the swinging closure may be adjusted to any. desired point and locked in any desired position to effectually control the draft ofthe stove. i y Y The shells 10 14 and other parts may be of any required size or shape, but will preferably be elliptical, as represented.

Having thus described the invention, what is claimed is- Inr a heating-stove a base-plate, an ash-pit extending from said base-plate, an intermediate plate bearing upon said ash-pit and eX- tending laterally thereof at the sides and with a central aperture communicating with said ash-pit, a grate supported within the ash-pit beneath said aperture, an outer shell bearing at the lower end upon the intermediate plate, an inner shell supported at its lower end upon said intermediate plate and inclosing said aperture and the grate beneath the same and provided with an opening near the smokelue and communicatiiw with the space between the shells, a top plbate bearing upon the upper ends of both of said shells, a smokeflue leading from said to plate and communi eating with the space getween the shells, a shut-off plate within said space between said smoke-flue and said opening in said inner shell, and a plurality of sA aced deilectingplates within said space an extending alternately upward from said intermediate plate and downward from said upper plate.

In testimony that I claim the foregoing as my own l have hereto ai'lixed my signature in the presence of two witnesses.
