Description
,3~
Backqround and Brief Summary of the Invention It is well known that a vast number of buildings are heated with fluid fuels, such as natural gas and fuel oil.
Moreover, the supply of thesè ~luid fuels to the buildings are sometimes interrupted because of cold weather and inade-quate quantities of the fuels available.
One solution to this lack of heat is the burning of available solid fuels, such as coal or wood. This, how-ever, causes a problem in that the furnaces burning fluid fuels are not compatible with burning a solid fuel. According-ly, a separate furnace has to be provided to heat the struc-ture or the fluid fuel burning furnace has to be modified.
Accordingly, it is a primary object of the present invention to provide a method of and apparatus for supplying supplemental heat to a building by burning a solid fuel in the event the supply of fluid fuel is interrupted.
Further, it is an object of the present invention to provide a method of and apparatus for supplying supple-mental heat to a building which is normally heated by burn-ing a fluid fuel that permits the additional heat to besupplied without modifying the building.
Further, it is an object of the present invention to provide apparatus for supplying supplemental heat to a building which is normally heated by burning a fluid fuel by positioning the apparatus outside of the building to be heated so that the danger of fire is reduced.
In accordance with the invention, a method of supplying supplemental heat to a building which is normally heated by burning a fluid fuel is disclosed and includes the steps of positioning a furnace disposed within a shelter outside near the building, the shelter having an inlet for receiving air and an outlet for passing air heated by the furnace out of the shelter~ An air duct is mounted between

FIG. 1 is a perspective view of apparatus construct-ed according to the present invention.
-3a-~3~5 FIG. 2 is an elevational end view, partly in sec-tion, o~ the apparatus shown in FIG. 1.
While the invention will be described in connection with a preferred embodiment and procedure, it will be under-stood that it is not intended to limit the invention to that embodiment and procedure. On thP contrary, it is intended to cover all alternatives, modifications and equivalents as may be included within the spirit and scope of the invention as de~ined by the appended claims.
Detailed Description of the Invention Turning now to the drawings, there is shown appara-tus 10 for supplying supplemental heat to a building 12 which is normally heated by burning a fluid fuel. Apparatus 10 is disposed at any convenient location outside near building 12, as long as the location is near an existing opening 14 into the building. As shown in FTG. lt the preferred location is near a window.
Apparatus 10 includes a shelter 16, which has a top 18, a bottom 20, an inside wall 22 nearest building 12, an outside wall 24 away from building 12, a front 26 and a back 28. An opening 30 covered by a screen 32 extends through outside wall 24 to act as an inlet for receiving ambient air.
An opening 34 extends through inside wall 22 to act as an out-let for passing heated air out of shelter 16. A door 36 coYers an access port in front 26 of shelter 16. Preferably, shelter 16 in constructed from an insulating material, such as masonry, to aid in preventing heat loss through the walls of the shelter and a lining 38, such as aluminum, is provided on the inside of shelter 14 for reflecting radiant energy emitted from furnace 40 disposed ~l~232~5 within the shelter. It is also preferred that inlet 30 be near bottom 20 and front 26 of shelter 14 and that outlet 34 be near top 18 and back 28 to provide the longest possible distance for the air to pass through shelter 14 which aids in heating the air.
Furnace 40 is used to heat the air as it passes from inlet 30 to outlet 34. The furnace is disposed and supported in shelter 16 by conventional apparatus, such as braces 41. As shown, furnace 40 is preferably a boxlike structure having a top 42, a bottom 44 and parallel side ~alls 46 and 48, which extend from front 50 to back 52. An insulat-ing material 54, such as fire brick, is provided in the bottom portion of furnace 40 to protect the furnace and a grate 56 extends across this bottom portion to support ~he solid fuel.
A door 59 is disposed over an opening in front 50 to permit access into furnace 40 for adding fuel or removing ashes.
A conduit 58 is disposed in the bottom portion of the furnace and within side wall 46 to provide an opening 60 beneath grate 56 which admits air to the burning fuel. A
damper 62 is pivotally mounted to the upper edge of conduit 58 to re~ulate the flow of air through the opening (the draft to the burning fuel). A chain 64 interconnects a conventional thermostat 66, such as a bimetallic thermostat, with damper 62 for controlling the draft to the solid fuel being burned in furnace 40. Preferably, thermostat 66 is at the same height as outlet 34 in shelter 16 to cancel the effect of fuel quality and ambient air temperatre to thereby provide a constant temperature at outlet 34.
An exhaust stack 68 is provided in top 42 of ~ur-nace 40 and extends through top 18 of shelter 16 so that ~23;~5 the exhaust gases from the furnace are removed from shelter 16 without mixing with the air therein. Preferably, this stack extends to a level above the roof of building 12 to inhibit the possibility of fire in the building.
A duct 70 is adapted to be mounted between opening 34 of shelter 16 and window opening 14 into building 17. The heated air, thus, passing through outlet 34 of shelter 16 is carried through duct 70 into building 12 to provide heat to the building in the event the supply of fluid fuel is inter-rupted~ When desired, a blower or fan disposed within a hous-ing 72 is mounted to duct 70 for drawing the air from shelter 16 and into building 12.
A blocking element 74 adapted to the mounted on said duct may be provided in the window opening on each side of the duct to inhibit the passage of any air other than the heated air being carried through the duct into building 12.
In operation, supplemental heat is supplied to building 12, which is normally heated by burning a fluid fuel by positioning shelter 16 having furnace 40 disposed therein outside near the building 12. A base 76, such as poured con-crete, is preferably provided at this location to prevent cor-rosion and other damage to the shelter. Air duct 70 is then mounted between shelter 16 and window opening 14. Doors 36 and 59 are opened to add solid fuel to furnace 40. The fuel is burned to heat air passing into shelter 16 from inlet 30.
The heated air is then transported through outlet 34 and duct 70 into building 12 to provide heat to the building in the event the supply of fluid fuel is interrupted~ Blocking ele-ments 74 may be mounted around :~23Z95 duct 70 in window opening 14 to inhibit the passage of any air through the window opening other than the heated air transported through the duct into the building.
