Complete Specification Left, 28th Apr., 1891-Accepted, 25th July, 1891
PROVISIONAL SPECIFICATION.
Improvements in Ventilators for Sewers, Public Buildings, Domestic
Apartments, and Spaces.
WILLIAM WELCH of 36 St. Georges Square, Portsmouth in the County of
Hants, Civil Engineer, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is the producing an auxitic action to the atmosphere
for heating and ventilating purposes by creating and direction of currents-and
also in destroying noxious and deleterious gasses-vapours and effluvium in
sewers-drains domestic apartments and spaces of any description.
In order that my invention may be practically comprehended-I accomplish the
same viz.-by the introduction either in the open-or enclosed-or partially
enclosed within pipes or conduits-superheating burners..or furnaces-in block or
other form-using therewith coal gas--water gas--mineral oil-coke or other
heat producing substance thereby creating the necessary change of temperature
and forming the desired currents to pass within the pipes or conduits for conducting
the superheated gasses &c. to the upper or outward atmosphere in a purified
condition-the burners or heating apparatus are used in horizontal-vertical-
inverted or angular position.
Dated this Twenty-sixth day of July 1890.

COMPLETE SPECIFICATION.
Improvements in Ventilators for Sewers, Public Buildings, Domestic
Apartments, and Spaces.
WILLIAM WELCH of 36 St. Georges Square Portsmouth in the County of
Hants, Civil Engineer, 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:-
For ventilating sewers-drains-tunnels-subways and spaces-I insert into
and through the crown or upper surface-or sides-open conduits, or pipes-
connecting the outer with the inner atmosphere as shewn on drawing Fig. 1A-B-
Within the conduit-or pipes at the mouth-or entry into the sewer-or spaces
attach and suspend from the top by a small pipe a superheating gas burning
apparatus as shewn-Fig. 1-C.
Preferably burners such as set forth in my Patent No. 5293-A.D.-1890-
Around the burners, an annular space-or channel way is provided between the
sides of the pipe-or conduits Fig. 1-D-D.-whereby a highly heated con-
centrated air current is induced-and producing an auxitic action to the surrounding
atmosphere within the sewer-space-&c.-and a rapid and commingling passage
upwards, delivering the air-and gasses to the outer atmosphere in a more
purified and innoxious condition, the conduits or pipes may be placed at any
sectional distances and the terminals may be at the level of the road or pathway-
or extended to a higher elevation if desired.
For ventilating and heating domestic apartments-public buildings and spaces-
I introduce through the side walls-Hoors-ceilings-and chimneys-conduit
boxes or pipes-connecting the outer and inner atmospheres as shewn on
drawing Fig. 2 & 3. Within the boxes or pipes 1 attach enclosed or partially
enclosed superheating gas burner apparatus as shewn A-Fig. 2 & 3, thereby

page_text: heating and raising the temperature within the boxes or conduits to any required
degree, and thus causing a rapid current of rarified air to pass within and through
the box or conduits for ventilating-and heating purposes-and in producing
an auxitic circulatory commingling action to the surrounding atmosphere either
inward outward-or upwards-the conduits or boxes-are fitted with slide
regulators for admitting and checking the desired volume of the air passages.
The superheating burner apparatus can be adapted and used within any ordinary
or improved ventilators-pipes or conduits now in use-with corresponding
beneficial results.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed-1 declare that what I
claim is
The improvements in ventilating sewers-drains-buildings-domestic apart-
ments and spaces, as herein before substantially described and set forth.
Dated this 27th day of April 1891.
WILLIAM WELCH.
