Abstract: An improved heating apparatus, for example for use as a wood or coal burning parlor stove and providing a significant heat output, has a construction for reducing thermally induced mechanical stress and for enabling the interior baffle assembly components of the apparatus to be removed therefrom, for replacement if necessary, without dismantling the apparatus exterior frame. The elements of the interior baffle assembly are interconnecting and are secured in a mechanically stable configuration by single point connection to the apparatus frame. The apparatus can have primary and secondary combustion chambers and a baffle system for directing flue gases along a circuitous path from the secondary combustion chamber to an exit aperture whereby a significant proportion of the heat of said gases is given up to the apparatus. A vertically oriented downwardly directed two component baffle separates the combustion chambers.

Abstract: A heating apparatus for operating in one or the other of two combustion modes has a frame assembly enclosing a primary and secondary combustion chamber. A baffle, separating the chambers, provides for gaseous communication therebetween. Preheated primary and secondary combustion air is directed in a controlled fashion to the front of the frame assembly across a viewing window to keep the window clear. The apparatus further has an off center damper movement system, means for defining a secondary air flow path through the primary combustion chamber, and a structure which can be changed for operation either as a wood burning or a coal burning stove.

Abstract: A solid fuel burning heating apparatus, used as a parlor stove, is also used for cooking. The stove is provided with a self-clearing top smoke chamber having a top cover over an aperture. A cooking tray is supported in the aperture when the stove is operating. The tray has a surface for holding coals and an opening communicating between the aperture and the interior of the stove. A perforate cooking surface is supported above the tray.

Abstract: A heating apparatus capable of efficiently burning both coal and wood has removable restriction elements for varying the rate of flow of air from an inlet port in the heating apparatus to a fuel holding combustion chamber. The restriction elements are positioned in the air supply path or paths from the inlet port to the fuel holding combustion chamber.
