UNITED STATES JOHN S: ANDREWS, OF HOLLYWOOD, CALIFORNIA.
WALL FURNACE.
Application filed April 17, 1924. Serial No. 707,104.
To all whom it may concern:
Be it known that I, J OHN S. ANDREWS, a citizen of the United States, residing at Hollywood, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Wall Furnaces, of which the following is a specification. I
My invention relates to household heating appliances, and more particularly to a gas burning heating furnace that is positioned on the wall near. the floor, or in a shallow niche or recess in the wall or, in some instances, in a pocket or recess that is formed in the floor.
The principal objects of my invention are,
to generally improve upon and simplify the construction of the existing forms of wall furnaces; and to provide a wall furnace that may be easily and cheaply produced, readily assembled or taken apart, and which may be easily and quickly cleaned; to provide a wall furnace of the character referred to that will utilize to the highest possible degree all the heat units developed by the combustion of gaseous fuel at the burner; to construct the furnace so that all noxious gases that may be developed as a result of the combustion of the gaseous fuel are positively carried to a vent pipe that leads to the ex- .terior of the building in which the furnace is located; and further, to provide an improved form of wallfurnaoe that will be 'highly effective in producing a continuous circulation of air through the room in which it is located, inasmuch as relatively cool air is taken from a plane just above the floor of the room and said air, after being heated in its passage through the heating device is discharged from the upper end thereof in an upward direction so as to circulate through the upper portion of the room.
Further objects of my invention are to provide a wall furnace that is strong and rugged in structure, relatively small in allover dimensions, but at the same time hav ing a relatively large area of heating surface, and further, to provide a wall furnace which, when properly constructed and installed, presents a neat and finished appear ance.
With the foregoing and other objects in view, my invention consists in certain novel features of construction and arrangement of parts that will be hereinafter more fully described and claimed and illustrated in the accompanying drawings in which- Fig. 1 is a front elevational view of a wall furnace of my improved construction, the same being shown in position within a wall niche or recess and with the lower portion of the furnace in vertical section.
Fig. 2 is a vertical section taken on the line 22 of Fig. 1.
-Fig. 3 is a horizontal section taken on the line 3-3 of Fig. 1.
Fig. 4 is a horizontal section taken on the line 44 of Fig. 1. i
Fig. 5 is a detail section taken on the line 55 of Fig. 2.
In the construction of my improved wall furnace, I make use of an outer shell or housing 10, preferably rectangular in form, open at its lower end, and having at its upper end and preferably at the front thereof an inclined perforated plate 11.
This outer shell is supported in an up right manner by suitable brackets 12, the latter bein secured to a wall so that said shell and the parts associated therewith are maintained with their lower ends in a plane a few inches'above the floor. As shown in Figs. 1 and 2, the wall furnace is illustrated as being positioned within a niche or recess R in the lower portion of a wall, but if desired this recess may be dispensed with and the furnace located on the lower portion of a wall.
Centrally arranged within the outer shell 10 is a vertically disposed heating tube 13, preferably'of oval shape in horizontal sec- ,tion and open at both ends. Located with in the lower end of this heating tube is a gas burner 14 of any desired form whlch is connected in any suitable manner to a 5 gaseous fuel supply pipe 15, the latter bemg referably provided with a cut-off valve 16 t at is locatedadjacent to the furnace.
The open end of burner tube, 13 communicates with a dome-shaped chamber 17 that is formed in the central portion of a cast metal plate 18, which latter is located in the upper portion of shell or housing 10. A somewhat similar pfate 19, preferably of cast metal, is arranged in the lower portion of shell or housing 10 a short distance above the lower end thereof, and the plates 18 and 19 are tied together by bolts 20 that pass throu h thev corners of said plates. Ar-
range between these plates 18 and 19 and enclosing the heating tube 13 'but spaced apart therefrom is a vertically disposed tubular member 22, preferably formed of sheet metal, said member being approximately rectangular in'horizontal section. An opening is formed in plate 19, which opening communicates directly with the space between the walls of the heating tube 12-3 and tubular member 22, and a corresponding opening 24 is formed in the upper plate 18 so that heated air which passes freely upward through the space between members 13 and may pass freely into ducts or chambers 27 therein lead from the ends of the chamber within said domeshaped member 17 to openings 28 that are formed in plate 18 directly above the end portions of the chamber between the members 22 and 25.
Formed through the plate 19 at the ends thereof and between the walls of members and 25 are outlet openings 29 for the fumes and burntproducts of combustion from the burner that is associated with the furnace, and an elbow fitting such as 30 may.
be connected to either one of these openings and to a vent pipe, such as 31, which leads through the wall to the exterior of the building in which the furnace is located. I provide two of these openings 29 in order that the elbow fitting may be located on either side of the furnace, and when so located the other one of the openings 29 may be closed by a readily removable cap, such as 32. Supported in any suitable manner directly beneath the burner 14 is a deflector plate 33 that is used to prevent the direct rays of heat from said burner from passing downward onto the floor directly from the furnace. If desired and in order to comply with certain building ordinances, the side and rear walls of the shell of easing may be covered with suitable fireproof material, such as asbestos.
In the use of my improved furnace, valve 16 is opened to admit gaseous fuel to a burner 14 and as the same is lighted, the heated aii and products of combustion therefrom pass upwardly through heating tube 13, thereby heating the walls thereof to a relatively high degree of temperature, and after passing into the chamber within dome-shaped member 17 the heated air and products of combustion pass outwardly through ducts 27, thence downwardly through openings 28, and thence downwardly through the narrow chamber or space between the members 22 and 25, consequently heating the walls of said members. The products of combustion from the burner finally pass into and through fitting 30 and from thence they pass to the outlet pipe 31.
Obviously the heating of the walls of members 22 and 25 within the furnace induces a circulation of air through said heater, said air being drawn into the open lowerend of shell or housing 10 and passing upwardly through the narrow chambers between the walls of chambers 13 and 22 and member 25 and the outer shell or housing 10. This air which enters the furnace in a comparatively cool condition rapidly absorbs heat from the heated walls within the furnace, and the air after thus becoming heated, passes through the chamber in the upper portion of the housing 10 and discharges from said furnace through perforated plate 11 and circulates upwardly through the room in which the furnace is located.
A wall furnace of my improved construction is comparatively simple, is very compact, has a comparatively large area of heating surface, is constructed so that all noxious gases and products of combustion are effectually preventedfrom entering the room in which the furnace is located, and said furnace is very effective in heating the air in the room in which it is located and effecting a thorough circulation of heated air.
It will be understood that various minor I changes may be made in the size, form and construction of my improved furnace without departing from the spirit of my invention, the scope of which is set forth in the appended claims.
I claim as my invention:
1. In a wall furnace, a vertically disposed housing, open top and bottom, upper and lower plates horizontally disposed within said housing and spaced apart from the walls thereof, spaced walls arranged between said plates so as to form a passageway between said walls and a passageway between the outer one of said walls and the housing, a heating tube disposed within the space within the inner wall, a burner at the lower end of said heating tube and a hollow dome-shaped member arranged on top of the upper plate for establishing communication between the upper end of the chamber in the heating tube and the end portions of the chamber between the spaced walls.
2. In a wall furnace, a vertically disposed housing, open to and bottom, upper and lower plates horizontally disposed within said housing and spaced apart from the upper plate for establishing communication 10 walls thereof, spaced walls arranged bebetween the upper end of the chamber in tween said plates so as to form a passageway the heating tube and the end portions of the between said walls and a passageway bechamber between the spaced walls and a tween the outer one of said walls and the products of combustion outlet duct leadin housing, a heating tube disposed within the from the lower portion of the chamber be- 15 space within the inner wall, a burner at the tween said spaced walls.
