Abstract: The specification describes a combination wood burning stove and oven comprising a housing having a combustion chamber, a heat transfer chamber and an oven disposed in the heat transfer chamber, a combustion product intake opening means communicating the combustion chamber and heat transfer chamber, a combustion product outlet opening in the heat transfer chamber for connection with an exterior flue pipe and an interior flue pipe means disposed in the heat transfer chamber adjacent the oven and interconnecting the intake opening means and outlet opening, the interior flue pipe means serving as a heat exchanger for the transfer of heat therefrom to the oven.
Abstract: The invention relates to a combustion method and apparatus for carrying out this method.The method comprises establishing (a) a combustion zone of hot embers above and near a grate and (b) a column of particulate fuel above and resting on said hot embers, supplying combustion air to said combustion zone only, flowing products of combustion generated at the interface between said hot embers and particulate fuel and in said hot embers downwardly through said grate, then upwardly in heat exchange relation to air in a space to be heated, and finally to exhaust.The apparatus comprises means for holding a column of particulate fuel above a grate, means for flowing air into a combustion zone above and adjacent to said grate at the bottom of said column only, and means for flowing products of combustion downwardly through said grate then upwardly through a heat exchange zone to exhaust.

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 heat exchange device is adapted to recover heat from the fire box of a wood burning stove or the like for heating ambient air in a room or other enclosed space. The heat exchange device is adapted to mount in a recess in a stove top in place of a lid which is normally supplied with the stove. The device according to the invention includes heat exchange means which extend into the fire box of the stove below the top surface thereof. The heat from the heat exchange device is transmitted into a main cavity of the device where the heat is transferred to air forced through the main cavity by a blower mounted to an outside surface of the device. Air exit means are provided on a surface opposite to the surface on which the blower is mounted to provide a passage for heated air into the room or other enclosed space to be heated. The device may also include a top mounted isolated handle for ease in handling the device such as for moving from one area to another.
Abstract: A wood burning stove having a lower main fire box and a vertically offset oven unit. Directly under the cooking surface of the lower firebox is an auxiliary firebox; the air supply inlet has means to selectively direct the incoming air to either firebox so that a small cooking fire can be used alone. The main firebox door has a glass panel and a removable stainless steel plate to reflect heat back to the glass to burn off accumulated deposits thereon.
Abstract: A solid fuel heater comprises a plurality of horizontal tubes defining between a vertical partition and an opposed vertical wall of the heater, a tubular grate with given ones of the tubes connected to a primary air source manifold header while others are connected to a secondary air source manifold header for preheating the air. The ends of the tubes opposite the connection to the headers open, respectively, to the upper side of the tubular grate for delivery of primary air and to the lower side for delivery of secondary air. The vertical partition wall forms a hot air passage for a downdraft operation leading to the stack. Preferably, a secondary grate underlies the tubular grate. By operating in a downdraft manner, only the lower ends of the solid fuel are burned, permitting low stack temperatures and long burning operation of the heater whether wood or coal fired.
Abstract: A so-called stack stove, especially for the burning of solid fuels and particularly wood has a hood or apron extending downwardly and outwardly along the upper portion of at least its front above the opening into the combustion chamber. A window door is mounted so as to be shiftable upwardly into the hood and locked therein so that it is substantially completely concealed by the hood when the stove is operated in a fireplace mode. In its lower position the door closes the chamber opening and the stove can function as a sealed stove with limited air entry for efficient combustion.

Abstract: This is a stove primarily for the burning of wood, but also capable of burning other combustible materials, which stove is characterized by a unique combustion chamber, together with a recirculating combustion chamber and baffle for more perfect combustion and characterized by a heat radiating chamber which may be closed so as to be used as an oven, and by a unique damper placement in combination with the exhaust flue pipe so adapted as to automatically activate in order to cool the flue pipe in the event it should exceed safe heat limits.
Abstract: An automatic wood burning heating stove has a fire chamber, a fuel feeding opening, closeable by an airtight door which is removable to convert the heater to an open fireplace. The door has a reflective ceramic surface on its inner face to direct heat toward preheating tubes having outlets directed above the fire zone. The door also reflects heat toward a downdraft preheating passage at the back of the stove. The draft preheating passage has a thermostatically controlled door which is closed when the stove is converted to a fireplace.
Abstract: A metal housing is provided including interconnected opposite side, front, rear, top and bottom walls and the front wall is provided with a large opening formed therein whose upstanding side edges are spaced inwardly of the adjacent sidewalls. A pair of opposite side closure doors are hingedly supported from opposite side portions of the front wall and are swingable horizontally between coplanar positions closing the large opening with their free swinging edges in close juxtaposition and open positions with the doors swung outwardly and rearwardly into positions closely paralleling the outer surfaces of the forward portions of the side walls. The top wall includes front and rear portions and the rear portion of the top wall has a flue outlet opening formed therein.
Abstract: A combination stove-fireplace assembly. A hood with a damper therein is movable vertically from a position wherein it is spaced from the assembly base -- wherein the assembly may be used as an open fireplace -- to a position in sealing engagement with the base -- wherein the assembly may be used as a stove or for "charcoaling". A sand-filled trench is provided at the base for insuring an air-tight seal between the base and the hood. Operating means for raising and lowering the hood include a crank exterior of the assembly positioned for ready access, and a means for locking the hood into the desired position to which it is raised. An ash bin is readily removable from underneath the firebox.
Abstract: This stove or fireplace control has a barrier across the lower front portion of the fire chamber to prevent air from flowing in under the grate. The unit when formed as a stove also includes frame means having spaced inner and outer walls with the inner wall defining a fire chamber and with the frame means having air inlet means at a lower portion thereof connecting to the space between the frame walls. A horizontally extending heater duct is provided in the frame means at the top thereof and is open at the front of the stove for receiving air from between the walls and conducting it horizontally and forwardly of the stove for discharge into the room for heating the same. Additionally the stove has an opening in the top thereof and a cooking plate is removably positioned over such opening in the top of the stove for direct exposure to the fire chamber on its lower surface.
