IMPROVEMENTS IN APPARATUS FOR FILTERING WATER AND OTHER LIQUIDS
Year: 1860

page_text: LETTERS PATENT to Thomas Wrigley, of Bridge Hall Mills, near Bury,
in the County of Lancaster, Paper Manufacturer, for the Invention of
"IMPROVEMENTS IN APPARATUS FOR FILTERING WATER AND OTHER LIQUIDS."
Sealed the 30th April 1861, and dated the 3rd November 1860.
PROVISIONAL SPECIFICATION left by the said Thomas Wrigley at the
Office of the Commissioners of Patents, with his Petition, on the
3rd November 1860.
I, THOMAS WRIGLEY, of Bridge Hall Mills, near Bury, in the County of
Lancaster, Paper Manufacturer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN APPARATUS FOR FILTERING WATER AND OTHER
LIQUIDS," to be as follows:-
According to my Invention, I cause the liquid to pass into the filtering
medium in a horizontal in contradistinction to a vertical direction. Thus
I use two vertical tubes or other shaped vessels, the one containing the
filtering medium, and the other the liquid to be filtered; and I form a com-
bined apparatus by placing a number of tubes or chambers in one vessel.

by the said Thomas Wrigley in the Great Seal Patent Office on the
3rd May 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
WRIGLEY, of Bridge Hall Mills, near Bury, in the County of Lancaster, Paper
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of November, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Thomas Wrigley, Her special license that I, the said Thomas
Wrigley, 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 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 "IMPROVE-
MENTS IN APPARATUS POR FILTERING WATER AND OTHER LIQUIDS," upon the
condition, amongst others, that I, the said Thomas Wrigley, by an instru-
ment in writing under my hand and seal, 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 Wrigley, 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 accompanying Drawings (that is to say)
According to my Invention, I cause the liquid to pass into the filtering
medium in a horizontal in contradistinction to a vertical direction. Thus
I use two vertical tubes or other shaped vessels, the one containing the
filtering medium, and the other the liquid to be filtered; and I form a com-
bined apparatus by placing a number of tubes or chambers in one vessel.
In the accompanying Drawing Fig. 1 is a vertical section of part of a vessel
containing the liquid to be filtered, one of the double tubes being also in
section; and Fig. 2 is a plan view of the same. The vessel containing the
water to be filtered is shewn at a, and is broken off at one end; and it may be
of any required size. To the bottom of this vessel are attached tubes b, of
wire gauze or other similar material, and on the outside of these, with spaces

page_text: between, are other tubes c, also of wire gauze, or the like material. The
spaces & between the two are filled with sand or other suitable filtering
medium. The water in the vessel a passes through the outward tubes c,
thence through the filtering medium d, and into the inward tube b, through
which it falls into a receiver e, and is conducted therefrom to any required
situation by a pipe f.
The chief object of my Invention is the filtration of large quantities of water
for manufacturing purposes, as in the paper trade, and I have therefore shewn
it as composed of a combination of filtering tubes, the number of which may
be increased according to circumstances; but an apparatus consisting of a
single pair of tubes may be employed when small quantities of liquid are to be
filtered. The tubes so called may be round, square, of any other desired shape,
and the wire gauze strengthened in any suitable manner according to
its area.
Having thus described and ascertained the nature of my said Invention,
and the manner in which the same is to be performed, I desire it to be under-
stood that I claim as secured to me under the above in part recited Letters
Patent,―
Firstly, the use of apparatus whereby the fluid is caused to pass into the
filtering medium horizontally.
Secondly, the use of a combined apparatus formed by placing a number of
tubes or chambers such as are described above in one vessel.
In witness whereof, I, the said Thomas Wrigley, have hereunto set my
hand and seal, this Second day of May, in the year of our Lord
One thousand eight hundred and sixty-one.
THOMAS WRIGLEY. (L.S.)
