The apparatus is c o m m e n d a b l e as an ingenious combination of two well-known systems of heating, and for its thorough utilization of the heat of the fire. A. PENROSE BENNER, PHILADELPHIA,
P/eiladelpMa 3IanifoM Hoetse-Heater---Is so arranged that the air m a y be heated by one furnace for each room of a building, arid conveyed thereto by separate pipes leading from the furnace. T h e furnace is provided with the necessary ash-pit, doors, dustand smoke-flues and other appurtenances ordinarily found in furnaces for this purpose, and the whole is inclosed in brick-work. T h e heaters are made of wrought-iron, not thinner than fourteen gauge, and are closely riveted at the joints to prevent leakage of coal-gas into the heater. T h e y are suspended within the brick-work by irons riveted to the heaters and built in the brick-work, respectively, and are arranged in a convenient manner, whereby to m a k e the best disposition of the space and to admit of a free circulation of heat and the products of combustion from the furnaces around and a m o n g them. The smoke passes from the furnace to tile stack at the u p p e r part of the brick-work, except when the fire is first started, when a damper m a y be opened into the dust-flue to increase the draught. A r r a n g e d around the fire-box is a c o m m o n cold-air receptacle, which forms part of the fire-box. Fresh air is admitted to the receptacle through flues. The base of each wrought-iron heater is connected b y a neck to this receptacle. A vapor-pan is placed at each side of the firebox for moistening the air. The upper portion of each heater is connected with a tight hot-air distributing flue, which leads to the a p a r t m e n t to be heated. The operation of the apparatus is as follows : T h e fresh air enters the receptacle through the flues, and passes t h r o u g h the separate heaters, which are exposed to the fire, and thence escapes t h r o u g h the separate distributing pipes into the several apartments to be heated. Thus each a p a r t m e n t is heated independently, and a room on a high floor cannot rob one on a lower floor of any portion of the heat intended for it.
