Bergs, A

A device which is inserted into the top of a fireplace for the purpose of increasing its heating capacity is described. It consists of a ''U'' shaped tube of rectangular cross-section, having a flat rear section with diverging arms which bend outwardly at their ends. To the end of one arm is attached a casing containing a blower or fan which blows cold or room temperature air into said tube, wherein it is heated, and passed through the other arm which is equipped at its end with a louver. The blower and louver are interchangeable between the said arms. The U-shaped tube is provided with a plurality of diamond shaped and round ducts passing through it, so that the combustion products such as hot gases, flame, and smoke pass through their ducts towards the chimney, thus heating the air within the U-shaped tube, surrounding the said ducts. The tube is provided with means for its attachment to the fireplace, and with permanent and removable baffles for directing the hot combustion products in the fireplace towards said tube.
