Abstract
The invention provides a stove for burning a charge of fuel by primary air directed either above or underneath through the firebed. A firebed support is defined by an array of alternating fixed and movable bars, the movable bars having a length greater than their width when viewed endwise and being rotatable between a vertical attitude in which they permit upward passage of air and downward passage of ash through said support and a horizontal attitude in which they permit build up of a layer of ash at the base of the firebed. An air distribution chamber has an inlet for primary air, a first outlet from which primary air passes to a space above the firebed and a second outlet from which primary air passes to a space below the firebed. An air diversion flap is movable between positions in which air is selectively directed through the first and through the second outlet. Control means operatively connects to the movable bars and to the air diversion flap to maintain them in an interlocked relationship so that the stove may be altered between one state in which the movable bars are directed generally horizontally and primary air passes through the first outlet and a second state in which the movable bars are directed generally vertically and primary air passes through the second outlet. Furthermore the stove has a housing having a generally upright front wall in which is formed an aperture for charging fuel and also for exposure of the firebed to permit enjoyment of its radiant heat and a firedoor that in a lowered position closes off the aperture. The firedoor is supported at either side on arms pivoted to opposed sides of the housing and spring loaded to balance the weight of the door. A top canopy has a front wall that defines with the upper region of the front wall of the housing a slot into which the firedoor may be raised clear of the aperture and concealed.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
