Improvements in the Construction of Chimneys Inside Buildings.
CHARLES JAMES HENDERSON Gentleman No. 6 Drumshugh Gardens Edinburgh do
hereby declare the nature of this invention to be as follows:-
The Chimney to be constructed of fireclay solid Bricks, in preference circular, and
each a
foot, more or less, in diameter, and about 6 inches in depth, pierced in the
centre by a circular cutting 6 inches, more or less in diameter, and around this,
smaller tubes, an inch or two in diameter-These tubes, built up, so as to form
continuous openings-the 6 inch one to carry off the smoke heat; the others, open
below, for fresh air to ascend, to near the roof of the Apartment, where the Chimney
ends, and the smoke carried off by a 6 inch Iron or other pipe, to outside, while
the air in the small tubes, would be discharged in the apartment, heated by passing
through the hot fireclay.
Dated this 22nd day of March 1887.
CHARLES J. HENDERSON.

Improvements in the Construction of Chimneys Inside Buildings.
CHARLES JAMES HENDERSON No. 6 Drumsheugh Gardens Gentleman Edinburgh
do hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
The chimney A to be constructed from the floor of solid fireclay Bricks, of best
quality, in preference circular, six inches or so in thickness and about a foot in
diameter perforated in the middle, for the smoke to escape by a circular cutting of B
6 to 8 inches diameter, and around this, small air passages to be cut C an inch or two
in diameter. These Bricks to be built up, the small holes only, left open at the floor
below, for the fresh air to enter and pass up, while the smoke heat of the fire, will
enter, a little higher up, by a cutting into the D, 6 to 8 inch smoke pipe. A pipe or
passage F to convey the fresh outside air to the small air passages; at any desired
height of the chimney, thus formed, where fresh warm air is desired; the top Brick
to be removed, and the smoke pipe continued, by an E Iron one, and the hot air from
the small tubes allowed to escape into the apartment. If desired the process may be
continued to the flats above fresh air entering from outside, a little way above where
the Iron pipe joins.
In order, partially, to prevent the ioo rapid escape of the smoke heat, thin projecting
metal plates may be placed between the Bricks.
The chimney being built up from the floor, the fire Heat, enters directly into it and
causes consumption of smoke.
Having now, particularly described and ascertained, the nature of my said Invention
and in what manner, the same is to be performed, 1 declare that what I claim is-
Utilizing the smoke heat of the chimney to warm the air passing up the small tubes
freed, as it will be of any impurities, in the manner described.
Dated this 23rd day of April 1887.
