IMPROVEMENTS IN APPLYING DEODORIZING FLUIDS TO SEWERS AND OTHER RECEPTACLES OF SEWAGE
Year: 1859

page_text: LETTERS PATENT to John Dales, of 11 and 12, Gresham House, Old
Broad Street, in the City of London, for the Invention of "IMPROVEMENTS
IN APPLYING DEODORIZING FLUIDS TO SEWERS AND OTHER RECEPTACLES OF
SEWAGE."
Sealed the 24th April 1860, and dated the 9th November 1859.
PROVISIONAL SPECIFICATION left by the said John Dales at the
Office of the Commissioners of Patents, with his Petition, on tho
9th November 1859.
I, JOHN DALES, of 11 and 12, Gresham House, Old Broad Street, in the
City of London, do hereby declare the nature of the Invention for "IMPROVE-
MENTS IN APPLYING DEODORIZING FLUIDS TO SEWERS AND OTHER RECEPTACLES OF
SEWAGE," to be as follows:-
This Invention has for its object improvements in applying deodorizing fluids
to sewers and other receptacles of sewage. In order to apply deodorizing
fluids to sewers, I employ a tank capable of containing the requisite amount of
deodorizing material to be supplied to the sewer at the spot at which the tank
is situated during several days, and from the bottom of this tank a pipe passes
into the sewer. The tank I prefer to be formed beneath the surface of the
ground, and when the sewer runs along a road, that the tank should be under
the foot path, and at the side of the tank a shaft is formed which passes up to
the surface of the ground, and is covered with a moveable door; in this shaft

page_text: there is a glass guage communicating with the tank which indicates the
amount of deodorizing fluid in the tank; the pipe from the bottom of the tank
also passes through this shaft, and on the pipe there is a tap, the plug of which
is connected with suitable apparatus actuated by clockwork for turning the
plug more or less, at different times of the day, so that more deodorizing
material may be supplied to the sewer at those parts of the day when more
sewage is passing through the sewers than at others; this clockwork and
apparatus is contained within the shaft. The tank may be filled with the deo-
dorizing fluid through a pipe passing from the shaft into the upper part of the
tank. Deodorizing fluids may be supplied in a similar manner to other
receptacles of sewage.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Dales in the Great Seal Patent Office on the
9th May 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
DALES, of 11 and 12, Gresham House, Old Broad Street, in the City of
London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of November, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-third year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said John Dales, Her special licence that I, the said John
Dales, my executors, administrators, and assigns, or such others as I, the
said John Dales, my executors, administrators, and 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
"IMPROVEMENTS IN APPLYING DEODORIZING FLUIDS TO SEWERS AND OTHER RECEP-
TACLES OF SEWAGE," upon the condition (amongst others) that I, the said John
Dales, 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.

page_text: • NOW KNOW YE, that I, the said John Dales, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:
This Invention has for its object improvements in applying deodorizing fluids
to sewers and other receptacles of sewage. In order to apply deodorizing
fluids to sewers I employ a tank capable of containing the requisite amount of
deodorizing material to be supplied to the sewer at the spot at which the tank
is situated during several days, and from the bottom of this tank a pipe passes
into the sewer. The tank I prefer to be formed beneath the surface of the
ground, and when the sewer runs along a road, that the tank should be under
the footpath, and at the side of the tank a shaft is formed, which passes up to
the surface of the ground, and is covered with a moveable door; in this shaft
there is a glass guage communicating with the tank, which indicates the amount
of deodorizing fluid in the tank. The pipe from the bottom of the tank also
passes through this shaft, and on the pipe there is a tap, the plug of which is
connected with suitable apparatus actuated by clockwork for turning the plug
more or less at different times of the day, so that more deodorizing material
may be supplied to the sewer at those parts of the day when more sewage is
passing through the sewers than at others; this clockwork and apparatus is
contained within the shaft. The tank may be filled with the deodorizing fluid
through a pipe passing from the shaft into the upper part of the tank.
Deodorizing fluids may be supplied in a similar manner to other receptacles
of sewage.
Having thus stated the nature of my said Invention I will proceed more
fully to describe the manner of performing the same.
DESCRIPTION OF THE DRAWING.
Figure 1 shows a transverse section of apparatus and of a sewer to which
the same is applied; Figure 2 is a horizontal section of the same. A is a
sewer; B, a tank or reservoir situated in any convenient position. Into this
tank or reservoir the supply of deodorizing fluid is placed; C is a glass guage
indicating the height of the fluid in the tank or reservoir. The reservoir is
connected by a pipe D, which as well as the interior of the reservoir or tank
should be made of a material not prejudicially acted on by the deodorizing fluid.
On the pipe D is a cock or valve suitably arranged to be acted on by clockwork,
so that the same may be opened more or less at certain times, according as more
or less of the deodorizing fluid is required, in order that the proper quantity of the
deodorizing fluid may be allowed to flow into the sewer according as a greater

page_text: or less quantity of sewage water is known to come down the sewer at particular
times. In a similar manner may a tank or reservoir and apparatus be applied
to other receptacles of sewage, and when applied to a water-closet the supply
may be constant or the apparatus may be arranged to act simultaneously with
the ordinary supply of water to the closet by connecting the key or handle,
cock, or tap, on the pipe from the tank or vessel containing the deodorizing
fluid with the cock or valve by which the ordinary supply of water is
obtained.
In witness whereof, I, the said John Dales, have hereunto set my
hand and seal, this Ninth day of May, in the year of our Lord One
JOHN DALES. (L.S.)
