I, CHARLES JAMES RICHARDSON, of No. 34, Kensington Square, in the
County of Middlesex, Fellow of the Royal Institute of British Architects, do
hereby declare the nature of the Invention for "IMPROVEMENTS IN APPARATUS
TO BE APPLIED TO CHIMNEYS OR FLUES OF BUILDINGS FOR ECONOMIZING HEAT,
AND REDUCING THE QUANTITY OF SMOKE PASSING INTO THE ATMOSPHERE," to be as
follows:-
This Invention has for its object improvements in apparatus to be applied
to chimneys or flues of buildings for economizing heat, and for reducing the
quantity of smoke passing into the atmosphere. For these purposes apparatus
is so constructed, and applied in the upper rooms of a building, that the heated
products of combustion from fires at lower parts of the building may be
advantageously made to heat the air of such upper rooms, and also, if desired;.
to heat water in cisterns placed in such upper rooms. The whole apparatus
it is preferred should be cased in by an ornamental or other case, and:
arranged so as to leave a space between the exterior of the apparatus and
the inside of the case to admit of the air in the upper. room. circulating
between the case and the apparatus.
In applying an apparatus to a chimney or rising flue from a fire situated
at a lower part of a building, in place of continuing such chimney or flue in

page_text: the wall of the building, where it passes into an upper room which it is
desired to warm by the heated products of combustion from the fire below, a
bend or branch, by preference of iron, is applied, which bend is caused to
protrude to some extent into the upper room; and at the upper part of such
bend a cistern may be formed or applied, and this is most conveniently done
by casting the bend and the water cistern in one piece of cast iron, but this
construction may be varied. The bend or protruding branch of the flue at
its upper part enters into a continuation of the chimney or rising flue made
in the wall of the building, and the products of combustion having passed
through the bend, then pass into such continuation of the flue or chimney,
and thence into the atmosphere. In applying such apparatus in an upper
room where the chimney or rising flue has been constructed, the portion
between the two ends of the bend is to be stopped.
In order to wash the products of combustion and precipitate the soot, jets
of water from a cistern above the room are thrown amongst the passing
smoke within the bend, and before or near where it enters the continuation
of the chimney or flue. The apparatus for supplying the jets of water is to
be arranged in such manner as to admit the quantity of water to be readily
adjusted, and to shut it off when required. The water so used to wash the
smoke is to be conducted off by a suitable pipe down into the drain. Pro-
vision may also be made, when water is not used, for catching the heavier
parts of the soot in a compartment below the bend projecting into the upper
room, and for removing such soot from such compartment.
