Surgeon, both of Bridport, in the County of Dorsetshire. "IMPROVEMENTS IN
VENTILATING, IN HEATING AND COOLING AIR, AND CONSUMING SMOKE AND GASES,
AND IN APPARATUS EMPLOYED THEREIN.”
"
The objects of our Invention are to carry out a better system of ventilation for
rooms, chambers, or buildings by a downward supply of atmospheric air from any
desired position above the fire or fires, or from above or below the roof of the
buildings, such air after having been heated or cooled being allowed to issue into
the rooms or buildings at any desired point or points; also at the same time to
withdraw vitiated air from such rooms or buildings, and consume the smoke and
gases evolved from the said fire or fires.
.
For these purposes we place at the back or other suitable part of a fire-place,
furnace, or other place wherein fuel is burnt, a heating chamber or chambers,
into which all or part of the smoke and gases from the fire, together with the flame,
are allowed to pass by one or more openings. The heating chamber or chambers
are contained within, or surround, or adjoin an air chamber which is in communi-
cation with the atmosphere by one or more supply pipes or passages, leading from
any desired position above the fire or fires, or above or below the roof of the
building, and from the said air chamber one or more other pipes or passages lead to
any desired point or points in the rooms or building to be ventilated or supplied
with heated or cooled air; and when cooled air is required an air cooler is inter-
posed between the said air chamber and the rooms or building. From the upper
part of such rooms or building we lead one or more pipes to the heating chamber
for conveying the vitiated air thereto, and from the heating chamber is a passage or
way connecting it with the chimney or uptake.
When the fire is lighted the heating chamber becoming heated by the smoke,
gases, and flame warms and rarifies the air in the surrounding or adjoining air
chamber, and consequently produces a downward supply of atmospheric air through
the pipes or passages leading from the points above, as before described, and this air
being warmed in its passage through the air chamber passes on through the pipes

page_text: leading therefrom into the rooms or building, going first through the air cooler,
when such is used. At the same time the vitiated air from the upper part of the
rooms or building is drawn through the other pipes before described into the
heating chamber (or air from any other convenient source may be conveyed thoreto),
and mixing with the smoke or gases in such chamber assists in consuming them t
before they escape into the chimney.
The air cooler may consist of a series of air passages, carried through or in contact
with a vessel containing any ordinary freezing mixture, so that the air in flowing
through the passages on its way to the rooms or building may become cooled. If
preferred the air may come into direct contact with the freezing mixture, and the 1
vessel containing it may be made to revolve by any suitable means.
The heating chamber may be provided both externally and internally, or either,
with gills, for the purpose of increasing the heating surface. To prevent injurious
action or chemical change of the air, such as is usually caused when it comes in
contact with heated iron, we coat the gills and the body of the heating chamber 1
with any suitable enamel.
The enamelling of gills for the purpose explained is applicable to all heating
apparatus where the air to be heated comes in contact with the hot metal.
