AN IMPROVEMENT IN DEODORIZING SEWAGE WATERS AND SEWAGE MATTER WHEN LIME IS USED
Year: 1856

page_text: LETTERS PATENT to George Julius Vertue, of Northam, in the Town
and County of the Town of Southampton, Merchant's Clerk, for the
Invention of "AN IMPROVEMENT IN DEODORIZING SEWAGE WATERS AND
SEWAGE MATTER WHEN LIME IS USED."
Sealed the 8th May 1857, and dated the 1st December 1856.
PROVISIONAL SPECIFICATION left by the said George Julius Vertue
at the Office of the Commissioners of Patents, with his Petition, on
the 1st December 1856.
I, GEORGE JULIUS VERTUE, of Northam, in the Town and County of the
Town of Southampton, Merchant's Clerk, do hereby declare the nature of
the Invention for "AN IMPROVEMENT IN DEODORIZING SEWAGE WATERS AND
SEWAGE MATTER WHEN LIME IS USED," to be as follows:-
As lime is my principal agent used for the purpose, it is essential that a kiln
should be erected at a convenient spot contiguous to the sewer pumping
station, drain, or wells, through which the sewage matter passes; the lime to
be used hot from the kiln, and placed in a tank or vessel in which works an
agitator driven by steam power or otherwise. A stream of hot or cold water
is led into the tank in sufficient quantities as to bring the lime into a perfectly
liquid form; the lime solution is then led through pipes (regulated by cocks
or valves) into the sewers, and thus, mixing by its own gravitation with the
sewage matter, purifies it, and renders it quite inoffensive and non-injurious to
the neighbourhood of the outfall or outlet of the sewers.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
JULIUS VERTUE, of Northam, in the Town and County of the Town of
Southampton, Merchant's Clerk, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of December, in the year of our Lord One
thousand eight hundred and fifty-six, in the twentieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
George Julius Vertue, Her special licence that I, the said George Julius
Vertue, my executors, administrators, and assigns, or such others as I, the said
George Julius Vertue, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times there-
after during tho 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 IMPROVEMENT
IN DEODORIZING SEWAGE WATERS AND SEWAGE MATTER WHEN LIME IS USED;"
upon the condition (amongst others) that I, the said George Julius Vertue,
my executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, 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 to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of
the said Letters Patent.
NOW KNOW YE, that I, the said George Julius Vertue, do hereby
declare the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
As lime is my principal agent used for the purpose, it is essential that a kiln
should be erected at a convenient spot contiguous to the sewer pumping.
station, drain, or wells, through which the sewage matter passes; the lime to
be used hot from the kiln, and placed in a tank or vessel in which works an
agitator driven by steam power or otherwise. A stream of hot or cold water
is led into the tank in sufficient quantities as to bring the lime into a perfectly
liquid form; the lime solution is then led through pipes (regulated by cocks or
valves) into the sewers, and thus, mixing by its own gravitation with the
sewage matter, purifies it, and renders it quite inoffensive and non-injurious to
the neighborhood of the outfall or outlet of the sewers.

page_text: And in order that my said Invention may be inost fully understood and
readily carried into effect, I will proceed to describe more fully the manner in
which I prefer to conduct the process over the sewer through which the sewage
to be deodorized passes, and at a short distance from the mouth of the said
sewer a circular vessel of wood or other material is erected, and in the centre
of this vessel is placed an upright shaft, having on it stirring arms, which
when the shaft revolves sweep the whole surface of the vessel at a short
distance from its bottom. To the vessel thus arranged a pipo leads in a con-
tinuous stream of water, and there is another pipe which leads the water after
it is mixed with the lime into the sewer through which the sewage is passing.
By the side of the mixing vessel there are lime kilns, in which the lime
required for the process is burnt, and from one of these kilns a workman con-
tinually takes quantities of the lime, while it is still hot from the burning, and
throws it into the mixing vossel, where it becomes mixed with the water also
introduced into the mixing vessel. Or, if sea water can be obtained, I find
it advantageous to use it in place of fresh water for mixing with the lime.
The quantity of lime which is necessary to deodorise a measure of sewage
will vary; but I find it generally advisable to employ the lime in the pro-
portion of twenty-six tons of lime per annum for every one thousand persons
of the population of the locality drained by the sewer.
Having thus described the nature of my Invention, and the manner of
performing the same, I would remark that I am aware that lime has heretofore
been mixed with sewage for the purpose of deodorising the same, I do not
therefore claim the same generally; but what I do claim is, the mixing the lime
while it is still hot from the burning with water and then adding the mixture
to the sewage to be deodorised.
In witness whereof, I, the said George Julius Vertue, have hereunto set
my hand and seal, this Twenty-eighth day of May, in the year of our
Lord One thousand eight hundred and fifty-seven.
Witness,
F. R. WITHERS,
Solicitor,
Southampton.
