SAMUEL A. CHENEY, OF NEVVBURYPORT, MASSACHUSETTS.
HOT-AIR FURNACE.
SPECIFICATION forming part of Letters Patent No. 659,208, dated October 9, 1900.
Application filed July 15, 1899. Serial No. 723,931. (No model.)
To all whom it may concern.-
Be it known that I, SAMUEL A. CHENEY, a citizen of the United States, residing at Newburyport, in the county of Essex and State of Massachusetts, have invented a new and useful Improvement in Hot-Air Furnaces, of which the following is a specification.
My invention relates to hot-air furnaces, and has for its object to provide an improved furnace of this class in which a single radiator is provided with two fire-boxes so arranged that either or both may be used, according to the amount of heat required.
WVith this object in view my invention consists in the improved construction, arrangement, and combination of parts hereinafter fully described, and afterward specifically pointed out in the claims.
In order to enable others skilled in the art to which my invention most nearly appertains to make and use the same, I will now proceed to describe its construction and operation, reference being had to the accompanying drawings, forming part hereof, in which Figure 1 is a view of the complete furnace in front elevation. Fig. 2 is a view in front elevation of the furnace with the jacket removed. Fig. 3 is a similar. view with the walls of combustion-chamber also removed. Fig. eis a vertical sectional view on the plane cutting through the furnace from front to rear, as indicated by the broken line 4 i of Fig. 2. Fig 5 is a similar view on the Vertical plane cutting through the furnace from side to side. Fig. 6 is a horizontal sectional view on the plane indicated by the broken line 6 6 of Fig. 2. Fig. 7 is a similar View on the plane indicated by the broken line 7 7 of Fig. 2.
Like numerals of reference mark the same parts wherever they appear in the several figures of the drawings.
Referring to the drawings by numerals, 8 indicates the jacket which surrounds the whole furnace, resting on a base 9 and closed by a top 10, out of which project the hot- air pipes 11, 12, and 13. There are two rectangular fire-boxes 14 and 15 set at a sufficient distance apart to permit of an air-fine 16 between them, said fire-boxes being ,each pro- Vided with a grate, as at 17 and 18, which separates them from ash- pits 19 and 20. The
air-flue 16 between the ashpits 19 and 20 and fire-boxes 14 and 15 is extended up centrally through the combustion-chamber 21 and discharges into the air-space between the top 23 of the combustion-chamber and the top 10 of the jacket. At the lower end the airflue is open to the height of the ash-pits, as at 24, thereby admitting air at the bottom of the flue. A smoke flue or pipe leads from the combustion-chamber and passes through the rear side of the jacket. 7
The combustion chamber is extended through the jacket by means of the frame 25, to which the door 26 is hinged, and doorframes 27 28 extend through the jacket from the ash-pits, doors 29 30 being hinged to such frames.
In operation fire in both or either of the fire-boxes can be fed through door 26, and the ashes from each fire-box will drop into the respective pit 29 or 30*, the ash-pit for each fire-box being the only medium through which draft or air can reach the fire, so that either fire-box can be used independent of the fact of the use or non-use of the other. The products of combustion, however, of each of the fire-boxes pass into the common combustion-chamber and out through the common smoke-pipe. The great advantage of this arrangement lies in the fact that either or both fire-boxes may be put into useb oth in severelycold weather, and either in mild weather. The air-chamber inclosed by the jacket entirely surrounds the fire-boxes and combustion-chamber, the air heated by contact with these parts com mingling in the space above the combustion-chamber with that discharged through the air-fiue, which air has passed between the fire-boxes and through the combustion-chamber.
When a single fire-box is used, the same parts (above the fire-boxes) are heated as when both are used, but of course not to as high a degree, so that the air is more mildly heated, while one-half the fuel is saved.
The fire-boxes are rectangular and substantially of the form of those of kitchen-ranges, which gives greater heating-surface for the area than a round or oval box would, thus in another respect economizing in fuel.
Having thus fully described my invention,
what I claim as new, and desire to secure by Letters Patent of the United States, is-
I. In a hot-air furnace, the combination with two separate ash-pits, two separate fireboxes above the same, a common fuel-door for said boxes of a combustion-chamber common to both of the fire-boxes, an air-flue extending vertically between the ash-pits, fireboxes and through the combustion-chamber, substantially as described.
2. In a hot-air furnace, the combination with two separated ashpits, two separated fire-boxes above the same, a common fueldoor for said boxes, of a combustion-chamber common to both of the said boxes, an air-flue extending vertically between the ash-pits, fire-boxes and through the combustion-chambers, and an air-chamber surrounding the combustion-chamber.
3. In a hot-air furnace, the combination with two separated ash-pits, two separated fire-boxes above the same, a common fueldoor for said boxes, of a combustion-chamber common to both of said boxes, an air-flue extending vertically between the ash-pits, and fire-boxes and through the combustion-chamber, a jacket surrounding the whole, an airspace'above the combustion-chambers and in communication with said jacket, an extension leading from the combustion-chamber and ash-pits respectively through the jacket and each provided with suitable doors, a smoke-pipe and hot-air fines leading from the furnace, substantially as described.
