PROVISIONAL SPECIFICATION.
Improved Method of Exhausting Steam, Foul Air, and Gases from
Buildings, and the like.
ROBERT COOKE No. 1 Norfolk Terrace, Bath Road Hounslow, Middlesex,
Dyer and Cleaner. I ROBERT COOKE do hereby declare the nature of this
invention to be as follows:-
To exhaust steam from drying rooms or shops, without losing any appreciable
heat, also noxious gases foul air &c. from public buildings & offices, by conducting
it through pipes or shafts to fires (whether stoves, furnaces, or steam boiler fires)
which would form the only means of combustion, this taking the place of all
ordinary draughts all other being excluded, the rate of exhaustion being equal to
the rate that the smoke &c. passes up chimney, thus working automatically.
Dated this Fifteenth day of November 1894.

Improved Method of Exhausting Steam, Foul Air, and Gases from
Buildings, and the like.
ROBERT COOKE 1 Norfolk Terrace Bath Road Hounslow, Middlesex Dyer and
Cleaner 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 principle involved is to conduct the steam foul air or noxious gasses from
the rooms or chambers by pipes shafts or other enclosed channels to draught of
fire necessary for combustion.
When stoves are used for drying purposes in laundries dye works &c. or where
used in shops & for heating purposes the stoves would have extra pipe from within
a short distance of the top of the room enclosed to stove underneath the bars
compelling the steam or foul air to pass through the fire which would improve
the combustion the number of cubit feet thus exhausted from top of rooms where
steam &c. is at its greatest would be in exactly the same ratio as the number of
cubit feet passing up smoke funnel.
In the case of the steam or humid air from the chamber of furnace dried bricks
where the drying is carried on, or a haymaker or any similar chamber where it is
desirous for the steam or gasses to be drawn off in the process I have a funnel
shaped or other suitably formed opening at the end of pipe or shaft for the gas
or steam to enter thence conducted by the pipe through the side of chamber to the
draught for furnace. The usual draught opening under the bars of furnace being
closed in, the pipe passes through such enclosure and supplies the air necessary for
the combustion in furnace at the same time carrying the steam or gasses through
the fire to flue.
When I use it for drawing off the steam from shop windows I use the funnel or
suitably shaped mouth of pipe thence by pipe from the enclosed window to the
bottom of enclosed stove and the same ventilating goes on automatically.

page_text: In the case of ventilating cellars & other chambers I extend the pipeing down
from draught of furnace to the desired position in chamber with funnel opening at
the end and an opening at the far end of chamber or place to the outer air thus
creating a continual current of pure air passing through the chamber A number
of rooms
or places may be ventilated by the same furnace the pipes being
connected at suitable places.
There are so many chambers to which this invention may be applied that I have
only enumerated a few of them but in all cases I exhaust the steam moist air or
foul gasses from the chamber desired to be ventilated and conduct it to the
draught of furnace. The furnace or stove being entirely closed in except for
replenishing the fuel or cleaning the only draught being supplied by my pipes
under the furnace and forming the only means of combustion.
In laundries dyers & other like drying rooms there may be several of these
pipes or shafts in the one room uniting under the furnace or other convenient
arrangement. The pipes with their funnel shaped opening near the ceiling or
where the steam is desired to be drawn off passing along until they terminate under
the furnace and supplying the draught.
In order to more properly understand the invention refer to accompanying
drawing.
A is the funnel shaped opening B the pipes or shafts C the entry to draught
under the furnace D furnace bars E the chimney flue.
Having now particularly described the automatic exhaust for steam foul air and
gasses what I claim as my invention is,
The drawing off steam foul air gasses & the like from rooms shops drying rooms
and other chambers desired to be ventilated by my automatic arrangement as
herein before described.
Dated this 13th day of August 1895.
