Application filed May 1, 1928, Serial No. 105,643. Renewed March 20, 1928.

This invention relates to stoves and other heating devices and has for its principalobiect the provision of means tor the eliiclent utilization of the heat of the products of combustion after they leave the tire pot, for cooking or general heating purposes.

Another object of the invention 1s to provide flue-means in communication with the lire pot ot a stove or other source of combustion, said means being arranged to torm a compartment whereby the heattrom said means is concentrated within the air space of said compartment.

A further object of the invention is the pro vision of a heating device forming acketed compartments with lines arranged 111 said ,acket connm'inicating with the combust on chamber of the heating device for directing the how of the products of combustion into heat interchanging relationship with the walls of said compartments, and being provided with dampers for selectively diverting the flow of combustion products for the pur- Jos-e of heating certain compartments or parts thereoit to a greater or less extent, or to 1mprore the draft by conduct-mg the products of combustion directly to the chimney pipe.

Still another object of the invention resides in the construction of heating apparatus 01' the class described which r ay, if desired, be used as an attachment to stoves already built, or incorporated into stoves, ranges, furnaces or the like at the time of their construction, ease of installation, and accessibility for the purpose of cleanin 7 Other objects ot the invention will appear as the following description of a preferred embodiment thereof proceeds.

In the drawings 2- Figure 1 is a perspective view, part being broken away, of a stove embodying the principles of my invention. I

Figure 2 is a section taken along the hne 2 of Figure 1.

Figure 3 is a section 33 of Figure 1.

Figure 4 is a section l i of Figure 1.

Figure 5 is a section of Figure 1. i

Figure G is a perspective view showing a modified form of the invention.

Referring now in detail to the several figures, the numeral 1 represents in general, a stove having the fire pot 2, feed door 3, ash pit 4c and ash tray the latter being pretertaken along the line taken along the line taken along the line ably provided with a draft damper 6. The stove preferably is supported upon legs 7 at a distance from the floor. The parts which have just been described are common to any stove and no claim is made to them as part of the present invention, except where necessarily combined with the structure now to be defined. i

The tire pot is preferably eXtendcd later ally as siown at 8 and 9 in Figure 2, the lateral extensions being formed with flanged openings 10 and 11 to receive the flue casing. 12. This casing is in general of an inverted U-shape having

vertical limbs

13 and 14 fitting down upon the flanged openings 10 and 11, and joined by a top transverse member 15 and preferably by an intermediate transvrse member 16. The flue casing may be made in upper and lower sections as shown, in which event the intermediate transverse members 16 are provided with flanged

openings

17 and 18 upon which the upper section oi the casing is fitted.

-he vertical limbs and transverse members are double-walled as shown, and provided inside with partitions, as follows, forming fiues. The

vertical limbs

13 and 14 in those parts which lie between the stove and the. intermediate transverse member are formed as single. conduits through which the products of combustion from the fire pot pass upward. At the level of the bottom of the intermediate transverse member, a horizon! tal partition 19 is provided in each of the ver 'ical limbs extending part way across said limbs and joining a. vertical partition 20 which eXtendsto the top transverse member and part way across the same, the partitions 20 being discontinuous adjacent the middle of the top transverse member affording an avenue of communication between the space wit-hinthe forward part of the top transverse member and the space within the rear part of said member, which latter space is in communication with the fines 21 formed by the

partitions

19 and 20 at the rear of the vertical limbs. Said fines are in open communication with the space within the intermediate transverse member through openings 22. "By means of this arrangementof fines, the hot products of combustion rise to the top of the verticallimbs through the forward flues 20' without normally having access to the intermediate transverse chamber, and then, passing through the space between the partitions- 20 in the toptransverse member, said products of combustion flow downwardly through the flues 21 and into the intermediate transverse member, being discharged from the same through the chimney pipe 23 after passing around the distributing baffles 40.

The vertical limbs of the flue casing, together with the top of the stove, intermediate transverse member, and top transverse member together, form

compartments

24 and 25 surrounded on their top, bottom, and sides by the extensive heat conductive surfaces formed by the top of the stove and the flue casing. It is clear that the heat of the proclnets of combustion, which usually pass directly into the chimney pipe and are wasted, are, in the present construction, conce-nt ated within the

compartments

24 and 25 intensely heating the air therein contained and assisting in cooking whatever objects may be arranged in said compartments for that purose. p By the novel arrangement of the partitions which I have above described, the flow of products of combustion is so regulated that the hottest gases contact with the sides of the compartments and with the top of the uppermost compartment, the top of the stove being in heat conductive relation to the lower compartment. In this manner both compartments are substantially equally heated. may be desirable, however, at certain times to regulate the heat so as to divert the maximum heat to the inter-mediate transverse member. This is done by means of dampers 26 and 27 controlling openings which lead from the front flues 20 of the intermediate transverse member. When these dampers are opened the combustion products are conducted directly to the intermediate transverse member and drawn directly out through the smoke pipe 23. This arrangement is of especial advantage when the upper compartment 24 is being used as an oven. It may happen that the upper part of said oven becomes unduly heated. The dampers 26 and 27 may then be opened diverting the heat to the lower part of the oven. Opening the dampers has the effect also of providing a direct path for the combustion products from the fire pot to the smoke pipe, thus improving the draft of the heating device. This is particularly advantageous when starting a. fire or when attempting to burn up a slow fire.

For convenience in cleaning out soot from the lateral extensions of the fire pot and from the

transverse members

15 and 16, I have pro vided the

removable lids

28, 29 and 30. The lid 28 preferably is flanged on all four edges and fits down over the open end of the upper section of the flue casing. The other lids are preferably flanged only on their front and back edges as shown at 31 and 32 in Figure 1, and rest upon horizontal flanges 33 provided at the edges of the respective sections with which they are associated. The cover 30,

pot, is provided with In that form of my invention shown in Fig ure 1 the stove has been provided, mainly for the sake of design, with hollow pillars and 36 below the vertical limbs of the flue casing, closed from said casing but in line therewith. These pillars are supported upon the upper wall of the ash pit 5, which has been extended laterally on both sides to meet said pillar This disposition of the ash pit walls makes it possible to use an ash tray of greater capacity than would otherwise be possible so that it is not necessary to remove ashes from the stove as frequently as is ordinarily required. The spaces between the

vertical pillars

35 and 36 and the side walls of the fire pot may serve conveniently as warming ovens.

in that rorm of my invention shown in Fig ure 6 there is no intermediate transverse memher, that the partitions within the flues may be dispensed with. In this embodiment of my invention the flue casing 37 may be added as an attachment to a stove already built, and f r this purpose it is preferable that the easing include the bottom transverse member 38 which in the form of my inventionvfirst described is part of the fire pot. The lower face of the bottom transverse member 38 is suitably apertured to fit down upon that part of the stove with which it is to be associated, and the furnace pipe represented by the reference numeral 39 leads from the lower face of the top transverse member.
