Year: 1875

page_text: LETTERS PATENT to Thomas Pape, of No. 96, Great Alfred Street, in
the Town and County of the Town of Nottingham, Hosiery Manu-
facturer, for the Invention of "AN IMPROVED METHOD OF AND APPARATUS
FOR FILTERING AND DEODERIZING SEWAGE, SO AS TO PREVENT RIVERS BEING
POLLUTED THEREBY.”
دو
PROVISIONAL SPECIFICATION left by the said Thomas Pape at the
Office of the Commissioners of Patents, with his Petition, on
the 3rd May 1875.
I, THOMAS PAPE, of No. 96, Great Alfred Street, in the Town and
County of the Town of Nottingham, Hosiery Manufacturer, do hereby
declare the nature of the said Invention for "AN IMPROVED METHOD OF Aand
APPARATUSFOR FILTERING AND DEODERIZING SEWAGE, SO AS TO PREVENT RIVERS
BEING POLLUTED THEREBY," to be as follows :-
It consists of one or more cylinders of wirework or perforated metal
sheets (with an outer covering) put on a horizontal shaft secured to a
wheel in the centre of the cylinder, and supported by rods or bars, each

page_text: end being open for the sewage to flow in; the cylinder, to be driven
with great velocity, and will separate the watery part of the sewage from
the solids; the solids adhere to the inside of the cylinder, and are
removed at intervals by a self-acting scraper (or by other means), and
carried outside by an inclined spout while the cylinders are in motion.
The machine (or machines) are driven by steam or other power, and
never stop except for repairs.
The process of deoderizing is by fixing an extra perforated cylinder
outside the first, and filling up the space with any known suitable
deoderizing substance.
The claim, chief features, and objects of this Invention are, to put a
quantity of machines on one or more horizontal shafts placed near the
sewer level, driven by steam or other power, so as to be enabled to filter
and deoderize a large quantity of sewage, the sewage flowing in at each
end of the cylinder, and the solid matter running out at the opposite
side.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Pape in the Great Seal Patent Office on 2
the 1st November 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
PAPE, of No. 96, Great Alfred Street, in the Town and County of the
Town of Nottingham, Hosiery Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent bearing date the Third day of May, in the year of our
Lord One thousand eight hundred and seventy-five, in the thirty-
ninth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Thomas Pape, Her special licence
that I, the said Thomas Pape, my executors, administrators, and assigns, a
or such others as I, the said Thomas Pape, 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 thercin expressed'

page_text: 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 METHOD OF AND
APPARATUS FOR FILTERING AND DEODERIZING SEWAGE, SO AS TO PREVENT RIVERS
BEING POLLUTED THEREBY," upon the condition (amongst others) that I,
the said Thomas Pape, my executors or administrators, by an instru-
ment 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 Thomas Pape, 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 thereof, reference being had to the accompanying
Drawings, that is to say:-
My Invention relates to the construction of a double self-acting cen-
trifugal machine to filter and deoderize sewage. The cylinders are fixed
on a steel shaft, as shewn in the Drawing Number 1; the shaft is sup-
ported by cast-iron standards or in brickwork, according to circumstances.
A pulley wheel No. 2 is fixed in the centre of the shaft, and a perforated
copper of zinc cylinder No. 3 is attached to the pulley wheel. The
sewage passes into the machine through pipes at either end, as shewn by
No. 4, and from the said pipes flows into a weir, as shewn by No. 5.
The cylinder revolves by steam power at a rapid rate, and the dead
matter accumulates on the inside of the inner cylinder, and is removed
by a self-acting scraper and brush, as shown by No. 6. When the
scraper has done its work the dead matter falls into an inclined spout or
spouts, as shown by No. 7, and passes out at both ends of the machine
into a vessel placed for the purpose of receiving it; and is easily removed
when.full. There is an outer screen No. 9 covering the inner cylinder,
leaving a sufficient space for the purpose of holding and collecting the
watery part of the sewage after the dead matter is separated, and at the
bottom of the said screen there are apertures through which the watery
part of the sewage flows away.
For the purpose of deoderizing there is an extra perforated or wire-
work cylinder No. S fixed between No. 3 cylinder and No. 9 screen,

page_text: forming a vacuum between No. 8 and No. 9, which is filled with a
deoderizing substance. The said case No. 8 can be taken off or dispensed
with when not required for the deoderizing process.
In witness whereof, I, the said Thomas Pape, have hereunto set my
hand and seal, this Twenty-eighth day of October One thousand
eight hundred and seventy-five.
Signed, sealed, and delivered
by the said Thomas Pape,
in the presence of
GEORGE WN. BINNS,
