Application June 6,1929, Serial No. 368,784 Renewed July 15, 1933' 2 Claims.- (Cl. 126-67) This invention relates to stove and furnace construction, the primary object of the invention being to provide a stove or furnace of the hot air type, and so constructed that the maximum amount of heat will be insured'with the minimum amount of fuel. 1

An important object of the invention is the provision of a stove or furnace including a body portion having a plurality of inclined air pipes ally through the casing 14 where it will be heated or flues fed from a main flue arranged at the rear of the body portion, the main flue being so constructed that the air will be preheated on its passage .to the inclined fiues.

With the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understod that changes in the precise embodiment of the invention herein disclosed, may be made Within the scope of what is claimed without departing from the spirit of the invention.

Referring to the drawings:

Figure 1 is a longitudinal sectional view through a stove or furnace taken on line 1--1 of Figure 4.

Figure 2 is a vertical sectional view taken on line 22 of Figure 1.

Figure 3 is a sectional view taken on line 3-3 of Figure 1.

Figure 4 is a sectional view taken on line 44 of Figure 1.

Referring to the drawings in detail, the device as shown comprises a body portion including side walls 5, rear wall 6 and front wall '7, the front wall being formed with an opening normally closed by means of the hinged closure 8.

As shown, the side walls and hinged closure are provided with openings 9, the openings being arranged in spaced relation with each other and formed throughout a great portion of the walls and closure. Positioned within the body portion is a circular firepot 10 which rests on the casing 11 that forms the ash pit of the heater, there being provided grate bars 12 for supporting the fire bed, in the usual and well known manner. The casing 11 is formed with a front opening normally closed by the hinged closure 13 so that the ashes may be readily removed.

Above the flrepot is a rectangular casing indicated generally by the reference character 14, which casing is formed with an opening closed by the hinged door 15 which may be opened to permit coal or other fuel to be thrown into the firepot. The casing 14 provides a passage for the smoke and products of combustion which pass upwardly from the firepot and-enter the stove pipe 16. Positioned within the rectangular casing 14, and disposed in parallel spaced relation with each other, are flues or heating tubes 17, which flues are in communication with air passageways 18 formed between the rectangular casing 14 and the body portion of the heater, to the end that air passing upwardly through the passageways, will be directed laterby the products of combustion passing upwardly through casing 14.

Arranged above the flues 17 is a substantially wide fiat flue 19 which has its ends open establishing communication between the passageway 18 Q 7, formed between the casing 14 and body portion of the device and the flue 19 so that air may pass upwardly through the flue 19.

As clearly shown by Figure 2 of the drawings, the flue 19 will direct the smoke and products of combustion laterally as it passes upwardly between the fiues 17, thereby thoroughly heating the flue 19 and air directed therethrough. A partition indicated by the reference character I 20 extends horizontally across the passageway 18 formed at the rear of the body portion to the end that air passing upwardly through the passageway will contact with the partition and be directed laterally into the fines 1'7 and 19.

Vertical partitions 21 are connected with the 35 inner casing and have their upperends terminating at a point adjacent to the lower edge of the door 15, the vertical partitions 21 being disposed at the corners of the body portion providing passageways 22. Horizontal plates 23 connect the vertical partitioning members 21 at the sides and Y front of the body portion so that air passing through the lower openings in the sides and front of the body portion will be checked in its upward passage and directed inwardly around the flrepot to be heated by the heat from the flrepot, from where the heated air will be directed laterally to the atmosphere through the upper openings 9.

The top of the'casing 14 is closed by the plate 6 24 which is provided with an opening 25 over which the stove pipe 16 is positioned, the plate 24 being provided with a circular opening closed by the cover 26, so that the cover 26 may be removed and the interior of the casing 14 readily cleaned 5 of soot which may collecton the'flues. The top of the passageway between the inner member and the body portion of the device, is provided with a plurality of openings 27, which openings permit the heated air to pass from the passageway to warm the room in which the device is positioned.

From the foregoing it will be obvious that due to the construction shown and described, the air drawn into the body portion of the device will be thoroughly heated before it is released in the room, thereby insuring the maximum amount of heat with the minimum amount of fuel.

I claim:

1. In a heating stove, a body portion, a fire pot within the body portion and spaced from the walls thereof, a rectangular casing above the fire pot and spaced from the walls of the body portion providing vertical passageways through the body portion, said body portion having openings establishing communication between the space around the fire pot and atmosphere, allowing heated air to pass laterally from the body portion, the bottom of the body portion having openings allowing air to pass into the space around the fire pot, horizontal partitions above said openings in the body portion and within the spaceat the front and sides of the fire pot restricting upward passage of heated air at the front and sides of the fire pot, means for conducting heated air from the rear of the body portion to the front of the body portion, and said body portion having openings in the top thereof, to permit heated air to pass from the body portion.

2. In a heating stove, a body portion, a fire pot within the body portion, a rectangular casing above the fire pot and extending to the top or" the body portion, said casing being spaced from the body portion providing vertical passageways, spaced inclined heating tubes connecting the passageways at the front and back of the stove, a Wide fiat inclined flue connecting the passageways at the front and back of the stove, horizontal partitions arranged at various levels and disposed within the vertical passageways, said partitions acting to retard upward passage of heated air and direct the heat laterally, the sides and front of the'body. portion having openings to allow air to pass into the body portion and circulate around the fire pot toheat the air, and said partitions being positioned above the openings and above
