page_text: LETTERS PATENT to John Linton, of Number 5, Ousegate, Selby,
in the County of York, Mechanical Engineer, for the Invention
of "THE UTILIZATION OF TOWN SEWAGE FOR AGRICULTURAL PURPOSES, AND
ALSO TO PREVENT THE POLLUTION OF RIVERS AND STREAMS, AND THE MACHINERY
AND APPARATUS FOR EFFECTING THE SAME."
Sealed the 10th April 1866, and dated the 12th October 1865..
PROVISIONAL SPECIFICATION left by the said John Linton at the
Office of the Commissioners of Patents, with his Petition, on the
12th October 1865.
I, JOHN LINTON, of Number 5, Ousegate, Selby,,in the County of York,
Mechanical Engineer, do hereby declare the nature of the said Invention
for "THE UTILIZATION OF TOWN SEWAGE FOR AGRICULTURAL PURPOSES, AND ALSO
TO PREVENT THE POLLUTION OF RIVERS AND STREAMS, AND THE MACHINERY AND
APPARATUS FOR EFFECTING THE SAME," to be as follows:-
My Invention consists in a series of moving filters revolving round a
number of circular, octagonal, hexagonal, or four-sided wheels, which give
a diagonal motion to the filters, causing them to move in the direction from
C to D, as shewn on the Drawing Sheet 2. The arrangements and
construction of this part of the Invention are as follows:-A number of
filtering boxes or sieves are to be attached to any requisite number of
endless chains, marked E on plan, Sheet Number One, which are to be put in

page_text: motion by steam or other motive power. The endless chains and filter boxes
or sieves are propelled either by circular, octagonal, hexagonal, or four-
sided wheels fixed on the shafts marked B, Sheet Number One. The frames
of the filter boxes or sieves are constructed of iron or other metal, with
an open space at the bottom and also at one end, into which space is
introduced the filtering sieves, constructed of two parts of fine woven
wirework or other material, leaving a space between the two parts of
wirework or other material to contain a sufficient portion of filtering
materials, composed of sand and charcoal, or any other material suitable
for the purpose; the filter sieves are fixed in the filter boxes with sett
screws, so as to be easily removed, with a strip of thin india-rubber between
the filter and the frame for the purpose of making the joined parts water-
tight. The outfall sewer is divided into as many branches as there are
separate chains of filters; each branch is fitted with a valve, which is
opened or shut by a chain attached to a lever and balance weight. The
sewage is conveyed direct from the outfall sewer into the filters. at C, on
Sheet Number Two; on its passage from C to D sufficient time is allowed
for the liquid sewage to pass through the filters, leaving the solid matter in
the sieves until it is discharged on to the mixing stage; the filtered water
is run off either by its own gravity or it is raised by steam or other power
and discharged into the nearest river or stream. The solid matter
deposited on the mixing stage shewn on Sheet One is, then incorporated
and thoroughly mixed with house ashes, sweepings from the streets, refuse
from flax, spent tan, sawdust, dried and ground clay, warp, or any other
refuse. suitable for the purpose, in the proportion of one-third sewage
to two-thirds of town refuse, with a small portion of gypsum or other
deoderizing powder; it is then mixed with a sufficient quantity of liquid
sewage to make it into a manure for agricultural purposes; it is finally
stored in a covered building until required for use.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 3
filed by the said John Linton in the Great Seal Patent Office on the
11th April 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
LINTON, of No. 5, Ousegate, in the Parish of Selby, in the County of
York, Mechanical Engineer and Surveyor to the Local Board of Health 3
for the District of Selby, send greeting.

page_text: WHEREAS Her most Excellent Majesty. Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of October, in the year of our
Lord One thousand eight hundred and sixty-five, in the twenty-ninth year,
of Her Reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said John Linton, Her special licence that I, the said John Linton,,
my executors, administrators, and assigns, or such others as I, the said
John Linton, 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 "THE.
UTILIZATION OF TOWN SEWAGE FOR AGRICULTURAL PURPOSES, AND ALSO TO PREVENT.
THE POLLUTION OF RIVERS AND STREAMS, AND THE MACHINERY AND APPARATUS FOR.
EFFECTING THE SAME," upon the condition (amongst others) that I, the said
John Linton, 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 John. Linton, 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:
My Invention consists in a series of moving filters revolving round a
number of circular, octagonal; hexagonal, or four-sided wheels, which give
a diagonal motion-to-the filters, causing them to move in the direction
from C to D, to be constructed as follows:-A-number of filtering boxes:
or sieves are to be attached to any requisite number of endless chains,
marked E on the plan and elevation, which are to be put in motion by
steam or other motive power applied to the crank àt X. The endless
chains and filter boxes or sieves are propelled either by circular, octagonal,
hexagonal, or four-sided wheels fixed on the shafts marked B. The frames
of the filter boxes or sieves are constructed of iron or other material, with
an open space at the bottom and also at one end, into which space is intro-
duced the filtering sieves, constructed of two parts of fine wove wirework
or other material, leaving a space between the two parts of wirework or
other material to contain a sufficient portion of filtering material, composed
of sand and charcoal, or any other material suitable for the
purpose.
The

page_text: filter sieves are fixed in the filter boxes with sett screws, so as to be easily
removed, with a strip of thin india-rubber between the filter and the frame
for the purpose of making the joining of the two parts water-tight. Every
separate chain of filters may be disconnected by moving the levers marked
S, which uncouples and throws the driving wheels out of gear, as shown
at R on the Drawing. The outfall sewer is to be divided into as many
branches as there are separate chains of filters; each branch is fitted with
a valve H that is opened or shut by a chain attached to a lever and
balance weight. The sewage is conveyed direct from the outfall sewer
into the filters at C; on its passage from C to D sufficient time is allowed
for the liquid sewage to pass through the filter, leaving the solid matter in
the sieves until it is discharged on the mixing stage. The filtered water
is run off either by its own gravity, or it may be raised by steam or other
power and then discharged into the nearest river or stream. The solid
matter deposited on the mixing stage is to be incorporated and thoroughly
mixed with house ashes, sweepings from the streets, refuse from flax, spent
tan, sawdust, dried and ground clay, warp, or any other refuse suitable for
the purpose, in the proportion of one-third of solid sewage to two-thirds
of town refuse, with a portion of gypsum or other deorderizing powder;
it is then mixed with a sufficient quantity of liquid sewage to make it into
suitable manure for agricultural purposes; it is finally stored in a covered
building until required for use.
In witness whereof, I, the said John Linton, have hereunto set my
hand and seal, this Tenth day of April, in the year of our Lord
One thousand eight hundred and sixty-six.
JOHN LINTON. (L.S.).
