P w- ATI'IDRNEYE Patented Nov. 2, 1948 uuirso YES 'l' EFICE RADIATOR STRUCTURE FOR HER HEATING FURNACES The invention relates to a heating plant, and more especially to a gravity type home heating apparatus.
The primary object of the invention is the provision of an apparatus of this character, wherein solid or fluid combustile material may be used therein for heating purposes in dwellings or other enclosures, the heating being eifected by hot air circulation, the products of combusion traveling in a horizontal direction from an elevated area downwardly, to opposite sides of the combusion chamber or dome, thence upwardly to the rear of the latter, and the spent products finally delivered to a smoke flue or chimney for discharge from the apparatus, thereby assuring maximum ccmbustion with a minimum consumption of fuel, and resultant heating qualities.
.Ancther object of the invention is the provision of an apparatus of this character, wherein it is susceptible of being cleaned without necessity of closing down the fire, the radiation flues being readily and easily accessible for efiicient cleaning thereof with dispatch and thoroughness, the apparatus being novel and unique in its entirety, as it promotes high heating efiiciency and fuel econcmy, the radiator arrangementin the apparatus affording greater length of fire or smoke travel, resulting in maximum heat radiation for distribution and a reduction in chimney or discharge fiue temperatures.
A still further object of the invention is the provision of an apparatus of this character, which is simple in construction, thoroughly reliable and efficient in operation, strong, durable, most compact, assuring a minimum consumption of fuel with a maximum heating quality, readily and easily controlled, conveniently handled, and inexpensive to manufacture and install.
With these and other objects in View, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings, which show the preferred embodiment of the invention and pointed out in the claim hereunto appended.
In the accompanying drawings Figure 1 is a vertical front elevation of a heating plant, partly in section, constructed. in ac cordance with the invention.
Figure 2 is a top plan View thereof with parts broken away for illustrating certain details of construction,
Figure 3 is a sectional View taken on the line 33 of Figure 1 looking in the direction of the arrows.
1 Claim. (Cl. 12699) Figure 4 is a fragmentary sectional viewtaken n the line 4-41 of Figure 1 looking in the direction of the arrows.
Figure 5 is a fragmentary sectional view taken on the line 5-5 of Figure 1 looking in the direction of the arrows.
Figure 6 is a sectionalview taken on the line (B t of Figure 1 looking in the direction of the arrows.
Figure 7 is a sectional View taken on the line l-'l of Figure 1 looking in the direction of the arrows. Similar reference characters indicate corresponding parts throughout the several views in the drawings.
Referring to the drawings in detail, A designates generally the gravity type heating plant constructed in accordance with theinvention, and comprising an outer sheet metal casing or housing til. it being sectionally set-up in anyv approved manner, and in this instance is of substantially rectan ular shape of vertical columnar form. Centrally of the casing or housing Ill interiorly thereof, at the forward portion-thereof, in vertical column-lfke manner, is builta lower ash pit ll, a superposed fire box i2, an upper combusion chamber 53, and a topping combustion domeor crowning head i l, respectively, the walls .l5vof these being brick lined at [6. The ash pit ii and the fire box it are accessible through the use of horizontally swinging doors ll and I8, respectively, which are located at the front of the casing or housing ill, and are latched closed in any suitabl manner, for example as at E9, best seen in Figure 1 of the drawings. 1
The fire box I2 carries therein removable grate bars 26, which may be of the group type orof the individual shakin type, and are supported in any selected manner. The lining to the ash pit l l, as well as the fire box [2 and. the combustion chamber iii are provided with air interstices 2!, communicative with air ports 22 opening through the front of the housing or casing Ill, and also as at 23 through the rear of the fire box IE, these being secondary air ports. It will be noted that there is no need of regulating the flow of air through outlet interstices 2| when air enters port 22. All air entering is from without the ash pit or feed door openings, and this is a very important improvement since air entering through the ash pit becomes saturated with ash dust and clogs interstices through which it rises. The damper 24, controlled by hand lever 25 operates indirect damper 32 as shown in Figure 4. The doors I! and I8 are provided with primary air ports 26 which are controlled by dampers 2'! and 28, re-
spectively, best seen in Figures 6 and 7 of the drawings.
, Built at opposite sides of the columnar ash pit H, fire box 12, combustion chamber l3 and dome or crownin head 14 are vertically directed banks of radiator flues 29, which extend in a horizontal direction from the front to the back walls of the housing, or casing I 0, and at their upper most portions 30 upwardly converge in overhanging relation to the dome or head l4, where communicating laterals 3! open into the latter. Direct draft from the firebox is controlled by a horizontal hinge action swinging damper 32, and location of the hinge at the bottom prevents burning out or warping. The flues 29 are horizontally and vertically intersected by smoke bailles 33 and 34, respectively, supported therein. The damper 32 confronts the chimney or smoke stack outlet 35, as best seen in Figure 4 of the drawings. The flues 29 are accessible for clean-out purposes through doors 36 arranged at the front and back of the casing or housing ID. The banks of radiator flues 29 are carried deep into the housing or casin l0, and the products of combustionand smoke fumes travel horizontally and vertically in circuitous courses within the said fiues 29 from the fire box and combustion chamber, downwardly and thence in an upward direction for discharge through openings ill into the smoke pipe 35. About the columnar ash pit, fire box and combustion chamber, and also the banks of flues, are spaces which receive air from circulating space 31. The heated air is delivered to distributing pipes 38 (see Figure 1). tweenplates 39 and the casing i0.
Adjoining the space 31 and depending from the top of the casing or housing ill at the outer sides of the banks of lines 29, and running from the front to the back of such casing or housing are i:
spaced vertically disposed circulating hot air insulation plates 39, these being considerably removed from the bottom of the casing or housing ID, for proper air circulation.
On the top of the crowning head or dome [4 of the furnace unit is a moistener or water pan 49 which is supplied with water in any suitable manner, while arranged near the top of the casing or housing ID outwardly of the upwardly converging portions of the plates 39 are laterally inclined supports 4| for air filters 42, and designed for filtering cold air so that the resulting heated air will be conditioned-and filtered.
The plant can be fired with solid or fluid fuel and operates with equal efficiency in either case,
and in the construction thereof assures a mini- 38 are the cold air intakes bemum consumption of fuel with a maximum of heating qualities. The plant is constructed for direct or indirect draft facilities, and is of a uniform and even burning character, it being readily and easily operated and controlled.
What is claimed is:
In a hot air heating furnace, the combination, which comprises, a centrally disposed furnace unit having a dome-shaped upper end; a plurality of radiator chambers rectangular-shape in vertical and horizontal cross section parallel to and spaced from the sides of said furnace unit, said radiators having horizontally disposed bafiles in the intermediate parts thereof and vertically disposed baffles spaced from the rearward ends providing horizontal and vertical passages respectively, the uppermost of said horizontally disposed baffles extending from the forward ends of the said radiators to points spaced from the vertically disposed baflles providing open areas for the downward passage of gases therein, and the lowermost of said horizontally disposed bafiles extending from the lower ends of the vertically disposed baliies, providing an L-shaped transverse web in each of said radiators; the lower element of said web extending forward to a point spaced from the forward end of each of said radiators providing open areas for the downward passage of gases therein, flue connections at the forward ends of the radiators positioned above the uppermost of said horizontally disposed bafiles and between the upper ends of the said radiators and the dome-shaped upper end of the furnace unit, and stack connections extending from the upper ends of the vertical passages formed by the vertically disposed baiiles and merging to a common outlet.
