riIRNAcE.
To allwhom it may concern Be it known that I, MICHAEL'JOSEPI'I (.irRANEY, a citizen of the United States, and
My invention relates generally to fur naces and more particularly, although not' necessarily, to hot air furnaces for burning 1 natural or coal gases, the purposeof my invention' being the provision of a simple, durable and inexpensive furnace'having a hot air chamber and gas "passages so associated therewith as to transmit to the'chamber with the greatest degree of efliciencyall'the; heat generated by the burning gases without the latter coming in actual contact with the air to be heated. Furthermore my invention provides a fresh air. chamber which communicates withthe gas passages in a mannerjto causethe combining and intermixing of the air andgases to further combustion of the gases. 1
I will describe one" form of furnacefem bodying my inventionand will 'thenfp'oint formed by'a spacing apart of the lower wall out the novel features thereof-inclaims. In the accompanying drawings nal section one form of furnaceernbodying Fig. 2. is a vertical transverse section taken on the line 2-2 of Fi'g. 1 andlooking in the direction of the arrows. 7
Referring specifically to the drawings, which similar. reference characters refer to;
similar parts, Fdesignates a fire box above which is arranged a hot air chamber C, and in the rear of wh ch 1s formed'an' La r chamber C. The fire box F contains a gratefG v of conventional form upon whichis sup-' f ported coal or other gaseous 'fueliwhich is introduced into the; fire box through an opening 15 formed in'the front. wall thereof. Air is admitted-tothe firebox F at a:
Qmeans'of a partitioniTfwhich is arranged in spaced relation to the front 'wallofthe chamber Cto provide a vertical passage 32 point below" the grate G through a port' 16 formed in the front wall of the'fire box. The draft created bythis admission of air' causes-the gases from the burning -fuel to pass upwardlyand'over the upper end of a bridge wall B, the latter being arrangedin spaced relation to their-ear wall 17 of the fire box so as to provide between the two. a
vertical passage 18. The lower end of the rear wall 17 is recessed to provide a port Specification of Letters Patent. -Patented Figural is a view showmgin longitudiformed between the rear. wall 17 and the front wall 21 of a fresh air chamber G. ,Fre'sh a rfrom'a point exteriorly of the building 111 which the furnaceis arranged is supplied to the hot'air chamber C through a pipe which communicateswith the rear 2 end of-an air heatln'g chamber C the for ward end of the latter in turn communicat Aug. 16, 1921.
V .lQ'which effects communication between the passage 18 and a vert cal passage 20 that is chamber and against which the incoming air is adapted to impinge. The side walls of the chamber C are spaced from the side walls of the furnace to provide vertically extending passages23'which are coextensive in length with the chamber and communicateajt their lower end withahorizontal passage 24 through the mediumof ports 25 arranged at the rear end of the horizontal passage 24. The horizontal passage 24 is astodirect the burning gases against the shoulder 22 and downwardly intoth'e pas-1 9O .municate with ahorizontal passagef26 at:
2, the opposite end of the passage 26 corn; municating with a vertical passage 28 which latter in turn communicates with 'chimney .or discharge flue 29.
A'r i admitted i dt 6hi-lllhllietv 1 b iaport 31-formed at the bottom of amrear wall of the chamber, such air beingfdi rected upwardlythrough the chamber and ultimately into the vertical passage 20 by throughfwhich the air 1 passes downw rdl from the chamber andintothe lower'end of I the passage20 through a port 23.
In the operation of the furnace the burn- I ing gases leaving the fire boX'F pass down- "wardly through the passage 18 entering the I 19. As the gases enter the passage 20 air through the chamber C is intermixed with the gases for the purpose of increasing-the combustion of the gases and thereby securing a greater heat efliciency. It will be understood that because of the direction of flow of the burning gases. from the fire box, a draft is created inwardly of the air chamber C so that a constant supply of .a1r to the burning gases is at all times maintained,
gases through the passages 24, 23 and 26 that 2 both side walls and the top wall of the chamber C aretraversed by these hot gases so that a most thorough-heating of the chamberis effected. Thus, as the fresh'air traverses the chamberC in passing into the chamber C, an intense heating of the air is obtained, After the heated air enters the chamber C, a further heating of the same is effected because one portion of its bottom wall is exposed to the v. fire box 1*, while another portion absorbsthe heat from the burning gases as they traverse the passage 26. The heated air passes from the chamber C to the desired points ofa buildingthrough the several pipes P while the burnt gases frointhe passage 26 enter the vertical passage 28 and leave the fur-.
nace through the fiue 29;
In the construction of the furnace all of.
its walls and partitions forming the chambers and passages are constructed of a heat absorbing material such as firebrick so that the heat from the burning gases can readily pass into' the air heating chambers, thus causing the heatingproperties of the gases to be completely spent between the passage of the gases from the fire box to the dis- 'fi charge fiue.
. although I have-herein shown and -de scribed only one formoffurnace embodying my invention, it is to'be understood that various changes and tmodificationsnmay be made herein without departing from the spirit of the invention and the spirit and scope'of'the appended claims.
Iclaim: 1 1. A furnace comprising, a fire box, a hot air chamber above the firebox and 0011 *tiguous thereto, an air heating chamber coma municatingwith the hot air chamber, and passages formed in the furnace to direct the "burning gases against the bottom wall of "the hot air chamber and completely around the air heating chamber.
2. A furnace comprlsing, a fire box, a hot air chamber above the fire box and con- I tiguous thereto, an air heating chamber comrecting theburning gases from the fire box into contact with the lowerwall of the hot air chamber andbeneath, around, and above the air heating chamber, and means. for admitting fresh air into said passages. v
4. A furnacecomprising, a fire box, a hot air chamber above and contiguousto the fire box, an air heating chamber communicating with the hot air. chamber, passages for directing the burning gases from'the fire box into contact with the lower wall of the hot air chamber and beneath, around and above the air heating chamber, and a fresh air chamber communicating withsaid passages ina manner to eifect the introduction of air into the passages.
