The invention herewith illustrated—patented by Mr. R. R. Jones, of Sprague, W. T—provides a fireplace for heating two rooms; the fire place is so constructed that each room can be heated by one fire, or both rooms by one fire, or one room by two fires. Fig. 1 is a sectional elevation and Fig. 2 a face view. The chimney is arranged in the Vall between two rooms, and is provided with two separate flues, below which is a fire box having two fireplaces. The back of one fire place is formed of an inclined cast iron plate, and the back of the other is formed of a plate, resting on a brick wall, and having its upper end resting under the lower end of the other plate; grates are formed in the lower portions of the fireplaces. The two faces of the fireplace box are furnished with openings which can be closed by hinged fenders; above the openings are registers. Within the .fire box are damper valves having rods extending through the casing, which are formed with notches to hold the valves in any desired position; it will be readily understood that by properly arranging these valves the products of combustion may be made to take any desired route to the chimney. When the valves are adjusted as shown in the full lines in Fig. 1, the smoke, etc., from each fire box passes up its .corresponding flue, and each fire box heats its room. The dotted and full lines show the positions the dampers may be placed in, and it is evident that by properly arranging them, the heat from either or from both fires may be used to heat either or both rooms.
