Fig. 3 is a horizontal sectiomon 'the line a b and Fig. 4 is'a horizontal section on the line The invention relates to the combination oij metal or cast-iron chimney fireplaces and ventilating-siiafts in such. a manner thatthe structure can be adapted as ,a'sub'stitute for a brick chimney in buildings for heating andventilat in g' purposes, and for heating and ventilatingrailway cars, 8m.

The iiiii'ain trunk and branch flues may he inserted flushwith the face of the partition, or project therefrom to any suitable distance; the heat passing'throngh the flues is, by my invention,

utilized for heating the apartment or car by;

its being diffused'zthrough the metal chimney,- a large amount of'heating-surface being thus exposed in the apartment. The main trunk may be carried up at the intersection of. two I partitions,and thus four fire-places can b} com- ,bined in the base B, so that one fire-ha ket ev may be provided =to each ofthe four partments, the base B being arranged aiiglewise at the corner of each room.
