Escaping Gas Innocuous.
I, WILLIAM PAULSON, Physician of Mountsorrel near Loughborough do hereby
declare the nature of my invention for VENTILATING SEWERS, AND RENDERING
THE ESCAPING GAS INNOCUOUS to be as follows:-
I connect the street gas standards, with the sewers by suitable pipes below the
ground.
The standard being hollow forms a tube for the conduction of foul air. .
By a short length of tubo or chimney of glass or other suitable material, I carry
the foul air within the glass lantern and near to the burner.
The ventilating cage at the top of tho lantern I charge with charcoal; or other
absorbent, disinfecting substance, then when the gas is burning the escaping foul
air is exposed to the heat of the flame, and products of combustion which heat also
serves to renovate the charcoal in filter above the lantern, and through which the
escaping gas must pass in the daytime.

Escaping Gas Innocuous.
I, WILLIAM PAULSON, of Mountsorrel, Loughborough in the County of Liecester,
Physician and Surgeon do hereby declare the nature of my invention for AN
IMPROVED MEANS OF VENTILATING SEWERS AND RENDERING THE ESCAPING GAS
INNOCUOUS, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
In carrying out my invention for Improvements in Ventilating Sewers and
rendering the escaping gas innocuous I cause the hollow standard of a street lamp
to communicate with the sewer in such a manner that the foul air may be free to
ascend the standard.
Where only one burner is used in the lamp or lantern I prefer to conduct the
foul air by a short length of suitable tubing attached to the upper end of the
standard just within the lantern and place the flame over the outlet, protecting
such outlet with miner's lamp gauze.
When more than one burner is used I prefer to conduct the foul air by a
longer length of suitable tubing, which may have a reflecting surface, attached
below to the hollow standard of which it forms a continuation and ending above
in a chamber at the upper part of the lantern.
This chamber I charge with a disinfectant such as charcoal-The floor of such
chamber is perforated or made in sections having a lining of wire gauze to retain
the disinfecting material in position, the under surface is enamelled to act as a
reflector.
Then when the lamp is lit the heat of the flame or flames dries the charcoal thus
renovating it and restoring its purifying power. The ascending foul air is filtered
through this charcoal chamber and disinfected before passing out at the top into
the air.
In order that this Invention may be fully understood, I shall now proceed more
particularly to discribe the same and for that purpose shall refer to the several
Figures in the annexed Sheet of Drawings, the same letters of reference indicating
corresponding parts in all the Figures,
A. Indicates the hollow standards,
B. B. The lamps or lanterns. .
C. The ventilating covers.
D. The gas pipes.
E. E. The gas burners.
F. The chamber for the charcoal or other purifying compound, contained in a
wire gauze or other perforated receptical.
G. The distributors.
H. H. The reflectors.
J. The tube for conducting the foul air from the hollow standards to the gas
flame, as in Figure 1-or into the nurifying chamber F as in Figures and a

page_text: In operation the foul air or sewer gas is caused to ascend up the tube J. by the
heat of the burner into or through the flame E. as in Figure 1, or directly into the
purifying and disinfecting chamber F. This tube may or may not communicate
with the hollow standards A. as desired, but if so, then the said hollow standards
may be made to also communicate by any suitable means with the sewer, so that
the foul air or gases may be free to ascend therein.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
The use of a disinfecting chamber so arranged that the heat of the gas flame
dries and restores its purifying power and I also claim the central conducting tube
substantially and for the purpose described.
