Year: 1875

page_text: LETTERS PATENT to William Blake. Williamson, of Bradford, in the
County of York, Merchant, for the Invention of "A NEW OR
IMPROVED SYSTEM AND MEANS OF PREVENTING THE POLLUTION OF RIVERS,
AND EXTRACTING AND CARRYING AWAY THE NOXIOUS VAPOURS FROM SEWERS.
SO AS TO PREVENT DELETERIOUS EFFECTS THEREFROM.”
PROVISIONAL SPECIFICATION left by the said William Blake
Williamson at the Office of the Commissioners of Patents, with
his Petition, on the 18th February 1875.
I, WILLIAM BLAKE WILLIAMSON, of Bradford, in the County of York,
Merchant, do hereby declare the nature of the said Invention for "A
NEW OR IMPROVED SYSTEM AND MEANS OF PREVENTING THE POLLUTION OF RIVERS,
AND EXTRACTING AND CARRYING AWAY THE NOXIOUS VAPOURS FROM SEWERS SO AS
TO PREVENT DELETERIOUS EFFECTS THEREFROM," to be as follows:-
This Invention has for its more especial object the construction of a

page_text: united system of drainage or sewerage from all the manufacturing towns
and villages of the West Riding of Yorkshire direct into the German
Ocean, at such place and in such manner as to render it impossible that
the sewage can be carried back by the tidal current either up the drain
or up the rivers which flow into the said ocean; but the said Invention
is also applicable to other districts of the United Kingdom to be
arranged according to the peculiar circumstance of the district. This
system consists of one main drain or culvert formed (by preference) of
brick and mortar made water-tight, commencing at or near Bradford in
the said West Riding, and taking the most suitable course; thence to
Leeds, and thence to Selby, and thence to a convenient part of the sea
coast between Hornsea and Witherinsea, and extending to some suitable
distance over the sea at low water but at some feet of elevation above
high water, thus providing for a constant discharge into the ever moving
ocean, which may be done by forming a pier or promontory, and
taking advantage of a natural formation of the shore; then at the
termination of and in connection with such drain or culvert I propose
to construct ventilating shafts of sufficient height, size, and form, or
wider at top than the bottom inside as will conduct the noxious vapors
or sewage gases to a suitable elevation, and there be discharged into the
atmosphere away from animal or vegitable life. Such ventilating shafts
I also propose to erect at various suitable places along the rout of the
drain to take off the sewage gages, then at suitable places near the
several towns and villages to be drained I construct branch drains and
connect them with the main drain or culvert, such branches being also
provided with ventilating shafts.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Blake Williamson in the Great Seal
Patent Office on the 18th August 1875.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth day of February, in the
year of our Lord One thousand eight hundred and seventy-five, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-.
cessors, give and grant unto me, the said William Blake Williamson,
Her special licence that I, the said William Blake Williamson, my
executors, administrators, and assigns, or such others as I, the said
William Blake Williamson, 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 King-
dom of Great Britain and Ireland, the Channel Islands, and Isle of
Man, an Invention for "A NEW OR IMPROVED SYSTEM AND MEANS OF PRE-
VENTING THE POLUTION OF RIVERS, AND EXTRACTING AND CARRYING AWAY THE
NOXIOUS VAPOURS FROM SEWERS SO AS TO PREVENT DELETERIOUS EFFECTS THERE-
FROM," upon the condition (amongst others) that I, the said William
Blake Williamson, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should par-
ticularly 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 William Blake Williamson, do
hereby declare the nature of my said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement and the accompanying Sheet of
Drawings, that is to say :—
This Invention has for its more especial object the construction of a
united system of drainage or sewerage from all the manufacturing towns
and villages of the West Riding of Yorkshire direct into the German
Ocean, at such place and in such manner as to render it impossible that
the sewage can be carried back by the tidal current either up the drain
or up the rivers which flow into the said ocean; but the said Invention
is also applicable to other districts of the United Kingdom to ¨be
arranged and constructed according to the peculiar circumstances of the
district. This system consists of one main drain or culvert formed (by

page_text: prefernce) of brick and mortar made watertight, commencing at or
near Bradford in the said West Riding, and taking the most suitable
course; thence to Leeds, thence to Selby, and thence to a convenient
part of the sea coast between Hornsea and Witherinsea, extending it to
some suitable distance into the sea at low water but so as to discharge
at some feet of elevation above high water, thus providing for a constant
discharge into the ever moving ocean, which extension may be done by
forming a pier or promotory, and taking advantage of a suitable natural
formation of the share; then at the termination of and in connection
with such drain or culvert I propose to construct a ventilating shaft of
sufficient height, size, and form (by preference wider at top than the
bottom inside) as will conduct the noxious vapours or sewerage gases to a
suitable elevation, and there to be discharged into the atmosphere away
from animal or vegitable life. Such ventilating shaft I also propose to
erect at various suitable places along the route of the drain to take off
the sewerage gases. Then at suitable places near the several towns or
villages to be drained I construct branch drains and connect them with
the main drain or culvert, such branches being also provided with

page_text: point above high-water mark, substantially as herein shewn and
described.
In witness whereof, I, the said William Blake Williamson, have
hereunto set my hand and seal, this Ninth day of August, in
the year of our Lord One thousand eight hundred and seventy-
five.
