Mayo, C

There is disclosed a fireplace screen comprising a frame which fits against the fireplace opening and a pair of doors hinged at the side which substantially close the fireplace opening and are fitted with glass panes so that the interior of the fireplace is visible from the adjacent room. The fireplace doors are of substantial thickness and are provided with vertical tubes inside the glass panes which have openings at the top and the bottom of the door to permit the passage of air from the room through the tubes and back into the room again. The tubes are preferably black to make them beat absorbing at least on the side facing the fireplace with the result that the tubes become quite hot and the air passing through the tubes is significantly heated. Heating of the air causes a chimney effect so that the air is drawn in at the bottom of the tube heated and exhausted at the top of the tube. The diameter of the tubes is preferably smaller than the spacing of the tubes so that a substantial area of the glass panes is left unobstructed and the fire in the fireplace is readily visible. The bottoms of the doors with the lower tube openings therein are spaced substantially above the bottom of the frame of the fire screen so that when the frame rests on the hearth of the fireplace there is a substantial space between the bottom of the tubes and the hearth of the fireplace for the passage of air from the room into the heat circulating tubes.
