page_text: LETTERS PATENT to James Gowans, of Edinburgh, in the County of
Mid Lothian, North Britain, for the Invention of "AN IMPROVED
CESSPOOL FOR PREVENTING THE ESCAPE OF SEWER GASES INTO HOUSES OR
OTHER BUILDINGS."
Scaled the 9th July 1872, and dated the 11th January 1872.
PROVISIONAL SPECIFICATION left by the said James Gowans at the
Office of the Commissioners of Patents, with his Petition, on the
11th January 1872.
I, JAMES GOWANS, of Edinburgh, in the County of Mid Lothian,
North Britain, do hereby declare the nature of the said Invention of
"AN IMPROVED CESSPOOL FOR PREVENTING THE ESCAPE OF SEWER GASES INTO
HOUSES OR OTHER BUILDINGS," to be as follows, that is to say :-
--
This Invention which relates to an improved arrangement of cesspools
to be applied to waterclosets, sinks, wash-hand basins, cisterns, baths,
lavatories, or other receptacles in communication with the sowers, has for
its object to prevent the escape of the sewer gases into houses or other

page_text: buildings wherein such receptacles are placed, and it consists in making
the said cesspools double, that is to say, the pipe between the receptacle
and the soil or other discharge pipe communicating with the sewer is
formed with two cesspools having a space between them with a pipe
leading from this space to the roof or summit of the building or other
suitable place outside the building. Any sewer gases that may pass up
through the first cesspool enter the space between the two cesspools and
pass off by the pipe leading therefrom, whilst the second cesspool
prevents their escape into houses or other buildings; at the same time
any gases that may be generated in the space between the cesspools pass
off in the same manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Gowans in the Great Scal Patent Office
on the 10th July 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
GOWANS, of Edinburgh, in the County of Mid Lothian, North Britain,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eleventh day of January, in the
year of our Lord One thousand eight hundred and seventy-two, in the
35th year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said James Gowans, Her special license
that I, the said James Gowans, my executors, administrators, and
assigns, or such others as I, the said James Gowans, my executors,
administrators, or assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "AN IMPROVED
CESSPOOL FOR PREVENTING THE ESCAPE OF SEWER GASES INTO HOUSES OR OTHER
BUILDINGS," upon the condition (amongst others) that I, the said James
Gowans, by an instrument in writing under my hand and seal, should
particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same

page_text: It will be seen that any gases which may escape through the cesspool
B as well as any that may be generated in the space 6 between the two
cesspools B and C, will pass off through the pipe E, so that the escape
of gases into the house or other building is by this means effectually
prevented. Or the double cesspool may be constructed as shewn at
Figure 2 wherein the traps a of the cesspools B, C, are composed of
diaphragms inserted through openings at the upper side of the cesspools.
Having now described and particularly ascertained the nature of my
said Invention, and the system, mode, or manner in or under which the
same is or may be used or practically carried into effect, I would obscrve
in conclusion that I do not limit myself to the precise arrangements
herein-before described, as the same are capable of considerable modifi-
cation, but what I consider novel and original, and therefore claim as the
Invention secured to me by the herein-before in part recited Letters
Patent is, the arrangement and construction of double cesspools as
herein-before described and shewn on the Sheet of Drawings hereunto
appended, and the employment thereof as and for the purpose herein-
hefore set forth.
hefore set forth.
In witness whereof, I, the said James Gowans, have hereunto set
my hand and seal, this Sixth day of July One thousand eight
hundred and seventy-two.
