Abstract
A wood stove is described having a firebox with a baffle mounted therein that extends forward from a rear wall terminating in a forward edge spaced from a front wall. The wood stove has a front opening with a door thereon that includes a window enabling visual observation of the fire in the fuel combustion chamber. Air is emitted into the front wall and is directed downward in a thin laminar flow over the glass to wash the glass and to create a flow of air and gases downward along the front wall, rearward along the bottom wall, upward along the back wall and forward along the baffle in somewhat of a circular flow. The firebox is mounted on a pedestal with a primary air supply means drawing air through the hollow pedestal to an intake within the hollow pedestal for directing air through a channel to the back wall. The back wall includes a diffuser plate for directing air into the fuel combustion chamber to wash the fuel from the rear to assist in primary combustion. Air is additionally emitted into the fuel combustion chamber through an air intake manifold that is mounted in the fuel combustion chamber rearward and upward from a transverse center line for providing air to the upburned hydrocarbon gases emitted from the fuel to burn such gases within the fuel combustion chamber. The baffle is insulated to minimize the loss of heat from the chamber through the baffle and to maintain the heat level within the chamber at a high level to support efficient combustion. The several air inlets to the combustion chamber enable the wood stove to operate very efficiently over the full range of heat burning settings to provide efficient burning while minimizing the exhaust of pollutants.

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.
