ABSTRACT:
A fireplace has an imperforate dished fire-pan, the sloping sides of which support the fire, which radiates through an opening in the wall of a conical enclosure superposed on the fire-pan. An outer frustoconical casing in most cases surrounds the enclosure, with an opening in register with the opening in the disclosure, and defines an air circulation space through which air circulates upwardly from beneath the fire-pan up into the room. A duct from the exterior of the room to be heated may extend into the space beneath the fire-pan, which space may also contain a water pan to humidify the circulating air. A fire control member is rotatable between the enclosure and the casing so as optionally to obturate the openings therein with either a mesh fire screen or a plate closing off the openings. The fireplace aims to provide complete and controllable combustion of wood fuel, and efficient space heating and, optionally, ventilation of a room in which it is situated.
