Abstract
A stove having walls which are shaped and supported to prevent warping thereof. A combustion chamber in the stove is defined by bottom and side walls positioned and oriented to maximize the space available for such a chamber. The walls of the combustion chamber have top caps thereon for ensuring and maintaining the proper positioning of those walls. Further holding elements are included in the stove to maintain the combustion chamber walls in position. An alternative embodiment of the stove includes front opening access doors.
Claims12
A stove comprising:
- a base;
- a stove front, rear and side walls on said base and extending away therefrom, said rear and side walls each including a central portion, an end portion on each end of said central portion, and offset portions connecting said central and end portions together, said end portions being essentially coplanar with each other and in a plane which is in spaced parallelism with a plane containing said central portion;
- a stove top wall on said walls and spaced from said base;
- at least one anti-warping bar on each of said front and rear stove walls, said anti-warping bars each extending upward from adjacent said base for essentially the entire length of said front and rear stove walls, said anti-warping bars and said wall portions providing structural support for a stove while increasing the heat output of that stove;
- a firebrick combustion chamber located within the stove and including a bottom on said base, and combustion chamber walls located inwardly adjacent said stove front, rear and side walls and extending from said base for a portion of the distance between said base and said top wall, those combustion chamber walls located adjacent said front and rear stove walls each having a channel defined therein for accommodating said anti-warping bars;
- holder support means located adjacent the intersection of said combustion chamber walls for positioning said combustion chamber walls and for reinforcing said combustion chamber wall intersections;
- and
- channel-shaped top caps resting on top edges of said combustion chamber walls.

A downdraft stove comprising:
- a base;
- a stove front, a rear wall and a pair of side walls on said base and extending away therefrom, said rear and side walls each including a central portion, an end portion on each end of said central portion, and offset portions connecting said central and end portions together, said end portions being essentially coplanar with each other and in a plane which is in spaced parallelism with a plane containing said central portion;
- a stove top wall on said walls and spaced from said base;
- a pair of transluscent access doors in said stove front wall;
- a firebrick combustion chamber located within the stove and including a bottom on said base, and combustion chamber walls located inwardly adjacent said stove front, rear and side walls and extending from said base for a portion of the distance between said base and said top wall, said combustion chamber front wall located adjacent said stove front wall extending from said base to immediately subjacent said access doors;
- a pair of draft tubes each attached at one end thereof to said stove top wall and depending downwardly into said stove, each draft tube having another end thereof located to direct air downwardly onto the upper surface of fuel located in said combustion chamber, the fuel burning from the upper area thereof downwardly;
- an anti-warping bar on said stove top wall, said bar extending from one side wall to the other side wall;
- holder support means located adjacent the intersection of said combustion chamber walls for positioning said combustion chamber walls and for reinforcing said combustion chamber wall intersections;
- and
- top caps each having a depending lip extending from said front, rear and side walls over the top edges of said combustion chamber walls with a top cap on said front combustion chamber wall located adjacent said stove front wall being integral with said stove front wall.
