FURNACE.

Application led April 16, 1926. Serial No. 102,376.

d furnish a heating chamber with communi cating air chambers in which cold air may be expeditiously and economically heated and supplied to oil burners constituting the main source of heat for the heating chamber.

The above and other objects are attained by a furnace construction that will be hereinafter specifically described and'` then claimed, and reference will now be had` to `the drawing wherein Figure 1 is a rear elevation of the furnace;

Fig. 2 is a horizontal sectional view of the same, and

Fig. 3 is a vertical longitudinal sectional View of the furnace taken on the line III- III Fig.'1. y

In the drawings, the reference numeral 1 denotes a heating chamber within an inclosure that may include a bottom wall 2, a front wall 3, a rear wall 4, side walls 5, and a top wall 6 havingan exhaust stack or flue 7 The front wall 3 has a bottom doorway 8 with an air supply pipe 9 adapted to direct a blast of air through the doorway 8 into the heating chamber 1 to sustain combustion therein and prevent'the escape of heated air at the doorway 8,

The rear Wall of the furnace has two spaced apart openings 10, preferably in a common horizontal plane, connnunicating with air heating chambers 11 mounted against the rear wall 4 ofthe furnace.

Extending downwardly between the air chambers 11 is a cold air supply or inlet pipe 12 provided with a conventional form of valve or gate 13 that may beL adjusted from either side of the furnace by a. valve control mechanism 14. The lower end of the cold air supply pipe 12 has lateral blanches `15 provided with nozzlesv16 extending into openings 17 in the confronting inner walls of the air heating chambers 11. The nozzles 16 supplyblastsof air to the air heating chambers 11 andthe blasts of air are directed transversely or. across the air heatlet pipes 18 which extend along the sidev walls 5 of the furnace communicating with opposed oilburners 19 having nozzles 20" protruding through openings 21 in the side walls 5. The oil burners 19are of a conventional fornrsupplied by oil pipes 2Q and said burners have suitable control valves or regulating mechanism 23. Y

The heated air from the chambers 11 to the oil burners insures atomization of oil and a proper admixture to sustain a perfect combustion within the heating chamber 1. Obviously the air heating chambers Vmay be attached to various types of furnaces and for this reason I do not care to confine my invention to the precise construct-ion and ar" rangement of parts shown, other than defined in the appended claims. 1

Vilhat I claim is :e

l 1. A furnace of the class described comprising a heating chamber, oil burnersfor heating said chamber, air heating chambers communicating with said heating chamber, hot air outlet pipes communicating with said air heating chambers and said burners to supply air thereto, and cold air inletl pipes communicating with said air heating chambers to supply air thereto, the cold air inlet pipes having their outlets aligned with and spaced from the inlets of the hot air outlet pipes so that the supply of cold air traverses said air heating chambers.

2. A furnace as called for in `claim Al,v wherein said oil burners are at the sides of said furnace in opposed relation, and'said air heatingr chamber at the rear side of said furnace with said hot air outlet pipes eX-` tending forwardly at the sides of said furnace.

3. Means for supplying heated air toja furnace for combustion purposes therein, coi'nprising air heating chambers ceinnnini` cat-ing with the furnace, hot air outlet pipes having open ends in said air heating cha-mbers, and cold air inlet pipes communicaty ing with said air'. heating chambers and adapted to discharge a blast of cold air intoV each air heating chamber in the direction of the hot air outlet pipes.v

In testimony whereof I affix my signature.
