To afl/ZZV whom it may concern:

`Be it'k'noW-n that I; JAMES W. WELDON, a'

citizen of the United States. Yand 'a resident of Toledo, in the countyofLucas and State of 'Ohio, have invented certain new and useful vImprovementsv inHeating-Stoves g and I do hereby declare the following to be a full,

' clear, and exact description of the invention, .such as will enable others sk'lled in the art to which it appertainsto make 'and use the same, reference being had to the accompanying drawings, and to the figures-of reference marked thereon', whichform a part of this' specification.

My invention relates `to heating-stoves of the class having abase-iiue section through which'the highly-heated gaseous products of combustion may be directed rior to being expelled from the stove throug the exit-flue.

The object. of the invention is the provision in a stove of this kind of a series of air- I ues adapted to receive cold air and expel it yso to the atmosphere ina 'highly-heated state, said iiues being so arranged lrelative to the ash-pan section and the descending, base, and ascending iues of the stove as to utilize the maximum heat-radiating surface of such arts for the heating of cold air, whereby to increase the efficiency and commercial value of tne stove. f i

The operation, construction, and arrange# ment of the parts of the invention are fully described in the following specification and Which- Figure 1 is a central vertical section of the stove embodying my invention taken on the dotted line a: in Fig. 2. Fig. 2 is a rear elevation of the stove with a portion of the casing broken away. Fig. 3 is yan irregular cross-section on the line w in Fig. 1, and

illustrated in the accompanying drawings, in

'F.ig. 4 is a partial vertical section on the lines y y in Figs. 2 and 3.

Referring to the drawings, 1 designates the combustion-chamber', 2 the ashfpan section,

and 3 the horizontal or prostrate base-flues of any ordinary type of base-burner. The base-lues 3 are separated by flue-strips 4 4 and communicate with the combustionchamber through the side descending iiues 5 5 and with the exit through the central ascending flue 6 in the usual-manner. In the construction of stoves of this class it has been customary to locate the base-fines 3 immediately beneath the bottom of the -ash-pan section., so .that they are separated by a single par- 'ation or ivan., while thiswau @partition becornes heated to a high state, due 'to its proximity to the. conibustion-chaniber, it is not suiiiciently heatedvto effect a further heating of the products of combustion descending tothe flues l3 from the coinbuStien-chamber, thus occasioninga complete loss ofthe heatradiating efficiency of such partition'. In `order to utilize `this lost 4heat energy, I inteipose a horizontal flue 7 between the bottom .of the ash-*pan section and the top S of the flues 3,. as shown. The ilues 7 is substantially thewidth of the ash-pan section and hasits forward end provided 'with a broad mouth 9, opening to the atmosphere, whereby to receive c'old air, and itsreai' end coinmunicatingwith a narrowed vertical ilue 10,

which is disposed immediately in advance of 'the ascending exit-flue 6 with its rear wall exposed to said iiue and its front wall'exposed to the ash-panand combustion-chamber sections. The upper end of this iiue terminates adjacent the top of the stove and iso en, as

yart-11, to expel to the atmosphere t e air,

which becomes highly heated in yits passage therethrough. ,y

'It is apparent that the lower and rear walls' of the iiue 7 lOvare `heated to a high state by the passing of the highly-heated gases of combustion around the lease-'ihres 3 and upthe ascending flue 6 and .that'the top and front walls of'said iiue are highly heated from the ash-pan and combustion-chamber sections, thus causing the air passing through said flue. to lbe acted on by the heat radiation from Yall of said walls,l and consequently heated to avery high stateprior to its expulsion to the rooni. l y

In order to` further utilize the otherwise lost radiation surface ofthe stove interior, I

make the flue-strips 4 4 hollow' to forni lues 12, 'with their bottoms opening below the stove for the admission of cold air thereto, as shown in F ig. 4. Therear end of each of these hollow flue-strips communicates with a vertical liue 13, which is located between the contiguous side descending ilue 5 and ascendi1ig1lue 6 of the stove, and has its front wall exposed to the ash-pan and combustionchamber sections, thus causing the air which 'passes through the flue 12 13 to. be continuously acted on by the heat radiation from the gases of combustion from the time said gases leave the combustion-chamber until they IOO have been expelled to the exit-Hue from the the heat radiation' from the rear wall of theashpan and combustion-chamber sections,

-The two vertical ilues 13 13 communicate products of combustion into said descending` flues.

The operation of the stove is as follows: The highly-heated products of combustion on leaving the eombustion-chamber` descend through the two side iiues 5 5, pass ardhnd the hollow flue-strips 4 4, and ascend thrcufh the common iiue 6 to find an exit from tie stove, thus heating the lower and relai' wall of i l the air-flue 7 10 and bothl side walls of' the air-flues 12 13. In addition to this the front walls of the ilues -10 and 13 radiate heat to said ilues from the ash-pan and combustioncliamber sections of the stove, and the upper wall or the top of the iiue. 7 radiates lieat'to said flue from the ash-pan section, thus utilizing all the available heat-radiating surface for the heating of cold air taken in from the vroom and materially increasing the heating eiliciencly7 of the stove.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

-1. rIhe combination in a stove having communicating side descending flues at its rear, horizontal base-fines, and an ascending flue disposed between the descending iiues, of vertical ilues separating each side descending flue from the ascending flue and open to the atmosphere adjacent their tops, and hollow flue-strips separatingthe base-flues andv having their bottoms opening below `lthe stove and their rearends communicating with the contiguous vertical iiue, substan- @muy as described. V

2. The combination in a stove having two communicating side descending flues, horiv zontal base-flues, and an ascending flue tor the productsof combustion, of a vertical airiiue dis vosed between each side descending flue an thecontiguous side of'the ascending flue, the front walls of said air-iiues forming a part of the rear wall ofthe ash-pan and coniustion chamber sections, and flue-strips separating the base-fines and having `their bottoms open to the atmosphereand their rear -eiids communicating with the vertical air-fines.

3. rl`he combination in a stove of horizontal base-flues, a central ascending and" two side .descending ilues communicating with the base-fines and disposed at the rear of the stove, and a-vertical air-flue disposed between each side descending flue and the contiguous side of the ascending llue and having its side Walis forming the contiguous side walls of the descending and ascending flues, said air-flue having both ends open to the atmosphere.

4.- r l`he combination in a stove of horizontal base-ilues, a central ascending and two side descending fines communicating with the base-fines and disposed at the rear side of the stove, a vertical air-flue between each side descending flue and the ascending lue and open at its top to the atmosphere, said air-flues having their side walls forming the contiguous side walls of the ascending and descending lflues 'andthcii' front walls e;\'- posed to the ash-pan and combustion-chamber sections, and hollow flue-strips separatingthe base-fines and having their bottoms open to the atmosphere and their rear ends communicating with the vertical air-fines, substantially as described. 'I

In testimony whereof I have hereunto signed my name to this specification in the presence of two subscribing witnesses.
