PROVISIONAL SPECIFICATION.
An Improved System of Smoke Purification.
I, GEORGE CROYDON MARKS, of 18 Southampton Buildings, London W.C,
Consulting Engineer and Patent Agent, (a communication from Maximilien
Ringelmaun, of 42 Boulevard Bonne Nouvelle, Paris, France), do hereby declare
the nature of this invention to be as follows.-
My invention relates to an improved system for the consumption of smoke that
is emitted from furnaces and chimneys of manufactories, houses and other
buildings, whereby the smoke so emitted instead of being expelled into the
atmosphere is drawn through to a common central station, where the soot is
precipitated and the gas emitted therefiom in a more purified or less obnoxious
condition.
In caying my invention into effect I provide the houses, manufactories, or
other buildings with a shaft or chimney which may be built within the wall of the
building or independently as a sheet iron pipe, of a length corresponding to the
height of the building; and auto this shaft I conduct the smoke or fumes from
the fires, furnaces oi stoves that may there be used.
The fumes are conducted down this shaft or chimney to a conduit that is laid
underneath the roadway which branches off the main conduit leading to the central
station where a fan driven from a steam, gas, or other motor operates to diaw such
fumes and expel to precipitating chambers where the soot is deposited, and the gas
subsequently emitted in a less obnoxious condition.
I provide a valve at the foot of the vertical shaft to open or close to the street
conduit, and I likewise provide valves upon the stove or furnace flues to open or
shut to the shaft.
I may also arrange for the ventilation of the various rooms in the building by
conducting a suitable pipe therefrom to the shaft, and in such a case I sometimes
provide a valve therein to open or close at will.
The upper end of the shaft I prefer to provide with a removable cover for
facilitating the cleaning of the shaft, and I sometimes provide a water pipe
leading thereto for the purpose of extinguishing fires.
I also provide street boxes at various intervals to receive valves upon the conduits
for the purpose of regulation, and cleansing from deposit of soot.

An Improved System of Smoke Purification.
I, GEORGE CROYDON MARKS, of 18 Southampton Buildings, London W.C.
Consulting Engineer and Patent Agent, (a communication from Maximilien
Ringelmann of 42 Boulevard Boune-Nouvelle, Paris, France), 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 aud by the following statement :-
My invention relates to an improved system for the cousumption of smoke that

page_text: is emitted from furnaces and chimneys of manufactories, houses and other
buildings, whereby the smoke so emitted instead of being expelled into the
atmosphere is drawn through to a common central station, where the soot is
precipitated and the gas emitted therefrom in a more purified or less obnoxious
condition.
Referring to the accompanying sheet of explanatory drawings-
Figure 1 is a part vertical section of a house constructed with my improved
system applied.
Figure 2 is a plan of streets laid out with smoke and fume conduits in accordance
with my invention while;
Figure 3 is a plan part in section of a central station in which a fan is operated
to draw the smoke and fumes into a precipitating chamber.
In carrying my invention into effect I provide the houses, manufactories, or
other buildings with a shaft or chimney B which may be built within the wall of
the building or independently in a sheet iron pipe or tube, of a length corresponding
to the height of the building; and to this shaft BI conduct the smoke or fumes
froin the fires, furnaces or stoves that may there be used.
The fumes are conducted down this shaft or chimney B to a conduit c that is
laid underneath the roadway which branches off the main conduit C leading to the
central station A where a fan V driven from a steam, gas or other motor M
operates to draw such fumes and expel to a precipitating chamber S where
the soot 18 deposited, and the gas subsequently emitted in a less obnoxious
condition.
I provide a valve U at the foot of the vertical shaft B to open or close to the
street conduit C and I likewise provide valves upon the store or furnace flues T
to open or shut to the shaft.
1 may also arrange for the ventilation of the various rooms in the building by
conducting a suitable pipe P therefrom to the shaft or airanging au outlet such
as P, and in such cases I sometimes provide a valve therein to open or close at
will. In like manner the exhaust steam from an engine such as N may be passed
into the main conduit which thereby performs the function of a condenser.
The upper end of the shaft B I prefer to provide with a removable cover K for
facilitating tho cleaning of the shaft, and I sometimes provide a water pipe E
leading thereto for the purpose of extinguishing fires.
I also provide street boxes J at various intervals to receive valves & upon the
conduit for the purpose of regulation and cleansing from deposit of soot.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manuer the same is to be performed, 1 declare that what I
claim 18-
1. An arrangement having chiefly for its object to prevent the development of
smoke in towns, and constituted by a main pipe or conduit Chaving branches
connected with shafts or channels B for a descending current, which communicate
with the fine places of buildings, the said main pipe C terminating in a station A
wherein a fun V is placed which draws soot, dust, gases, vapours and miasma,
and foices them into one or more depositing chambers S.
2. An improved system of smoke purification substantially as described and
illustrated in the accompanying drawings.
