Abstract
A portable camp stove is disclosed. It consists of a frusto-conical main body, a preheating chamber, and spiral flue chambers. The stove may be placed over a fire in a pit in the earth, or the stove may completely contain a fire within it when its bottom plate and legs are attached. Other accessories of the stove include a stovepipe and oven combination, a water heating system, and a grill and a rotisserie.
Claims18
A portable camp stove comprising:
- a generally frusto-conical main body defining a main combustion chamber;
- an open bottom which allows for the placement of the stove over a fire in a pit in the earth;
- means including at least one cylindrical section above said frusto-conical main body, forming a spiral flue chamber having an inlet in communication with said combustion chamber and an outlet, said spiral flue chamber containing at least one baffle that delays the escape of hot gases from said inlet to said outlet;
- a corrugated metal divider, located at the bottom of said frusto-conical main body, which together with said frusto-conical main body forms a preheating chamber in which air traverses from an opening means in said frusto-conical main body and is preheated before the air enters the main combustion chamber through an opening means in said corrugated metal divider.
1 more element
A stove comprising:
- a generally frusto-conical main body;
- means including a first cylindrical section, disposed above said frusto-conical main body, forming a substantially horizontal flue chamber, said horizontal flue chamber containing a bottom opening and a top opening, said top and bottom openings positioned, along with at least one vertically disposed gas deflecting baffle connected to stove plates which form the top and bottom of said cylindrical section, such as to form an indirect channel between said top and bottom openings;
- means forming a second cylindrical section, disposed above said first cylindrical section, forming a second substantially horizontal flue chamber, said second horizontal flue chamber containing a bottom opening and a top opening, said bottom opening and said top opening positioned, along with at least one vertically disposed gas deflecting baffle connected to stove plates which form the top and bottom of said cylindrical section, such as to form an indirect channel between said top and bottom openings;
- means forming a third cylindrical section, disposed concentrically around said first cylindrical section, said first and third concentric cylindrical sections forming a first air preheater channel via a substantially annular path formed by a first opening communicating with the interior of the frusto-conical main body, and a second opening communicating with the second flue chamber;
- means forming a fourth cylindrical section, disposed concentrically around said second cylindrical section, said second and fourth concentric cylindrical sections forming a second air preheater channel via a substantially annular path formed by a first opening communicating with the first flue chamber, and a second opening communicating with an exterior environment.
