Year: 1863

page_text: LETTERS PATENT to John Henry Johnson, of 47, Lincoln's Inn Fields,
in the County of Middlesex, Gentleman, for the Invention of "A
FILTERING APPARATUS FOR TREATING BY PRESSURE OILS, SYRUPS, AND ALL
SORTS OF LIQUIDS SUSCEPTIBLE OF FILTERING."-A communication from
abroad by Edmond Marquis de Ruffo Bonneval and Joseph Mouren,
both of Marseilles, in the Empire of France.
Sealed the 9th October 1865, and dated the 24th April 1868.
PROVISIONAL SPECIFICATION left by the said John Henry Johnson
at the Office of the Commissioners of Patents, with his Petition, on the
24th April 1863.
1, JOHN HENRY JOHNSON, of 47, Lincoln's Inn Fields, in the County of
Middlesex, Gentleman, do hereby declare the nature of the said Invention
for "A FILTERING APPARATUS FOR TREATING BY PRESSURE OILS, SYRUPS, AND ALL
SORTS OF LIQUIDS SUSCEPTIBLE OF FILTERING," a communication from abroad by
Edmund Marquis de Ruffo Bonneval and Joseph Mouren, both of Marseilles,
in the Empire of France, to be as follows:-
This Invention consists in the employment of a peculiar arrangement of
apparatus for filtering liquids, whereby such operation may be effected under
pressure. The liquid to be filtered is contained in a vessel or tank, to which
a suction and force pump is connected, which pump is also in communication
(by means of a pipe) with a strong filtering vessel. The filtering vessel is
provided with a man-hole at the top and a grating at the bottom, upon which

page_text: grating is placed the filtering medium, consisting of felt or other suitable
material. Immediately beneath the grating, and secured to the filtering vessel
or otherwise, there is fitted a hemispherical or other receiver, in which the
filtered liquid is collected and drawn off by a central pipe and stop-cock. The
liquid to be filtered is pumped into the filtering vessel, and the pumping is
continued after such vessel is full, in order that the liquid therein may be in a
state of compression, which state facilitates and expedites the process of
filtering by forcing the liquid through the filtering medium. In some cases
this apparatus may be employed as a press, as, for example, by introducing
olives into the filtering vessel, and injecting and forcing therein hot water
under considerable pressure, the double effect of the press and the filter or
purifier is obtained.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Henry Johnson in the Great Seal Patent Office on
the 24th October 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
HENRY JOHNSON, of 47, Lincoln's Inn Fields, in the County of Middlesex,
Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of April, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-sixth year of ler
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said John Henry Johnson, Her special license, that I, the said John
Henry Johnson, my executors, administrators, and assigns, or such others as
I, the said John Henry Johnson, my executors, administrators, or 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 "A
FILTERING APPARATUS FOR TREATING BY PRESSURE OILS, SYRUPS, AND ALL SORTS
OF LIQUIDS SUSCEPTIBLE OF FILTERING," a communication to me from abroad by
Edmond Marquis de Ruffe Bonneval and Joseph Mouren, both of Marseilles,
in the Empire of France, upon the condition (amongst others) that I, the said
John Henry Johnson, my executors or administrators, by an instrument in
writing under my hand and seal. or under the hand and seal of one of them,
should particularly describe and ascertain the nature of the said Invention,

page_text: 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 Henry Johnson, do hereby declare
the nature of the said Invention, and in what manner the same is to bo
performed, to be particularly described and ascertained in and by the follow-
ing statement, reference being had to the accompanying Drawings, and to tho
letters and figures marked thereon, that is to say :-
The said Invention consists in the employment of a peculiar arrangement
of apparatus for filtering liquids, whereby such operation may be effected
under pressure. The liquid to be filtered is contained in a vessel or tank, to
which a suction and force pump is connected, which pump is also in commu-
nication (by means of a pipe) with a strong filtering vessel. The filtering
vessel is provided with a man-hole at the top and a grating at the bottom,
upon which grating is placed the filtering medium, consisting of felt or other
suitable material. Immediately beneath the grating, and secured to the
filtering vessel or otherwise, there is fitted a hemispherical or other receiver,
in which the filtered liquid is collected and drawn off by a central pipe and
stop-cock. The liquid to be filtered is pumped into the filtering vessel, and
the pumping is continued after such vessel is full, in order that the liquid
therein may be in a state of compression, which state facilitates and expedites
the process of filtering by forcing the liquid through the filtering medium.
In some cases this apparatus may be employed as a press, as, for example, by
introducing olives into the filtering vessel, and injecting and forcing therein,
under considerable pressure, hot water, the oil will be expressed, and thus the
double effect of the press and the filter or purifier is obtained.
And in order that the said Invention may be fully understood, I shall now
proceed more particularly to describe the same, and for that purpose I shall
refer to the several Figures on the Sheet of Drawings hereunto annexed, the
same letters of reference indicating corresponding parts in all the Figures.
Figure 1 represents in elevation and section the entire apparatus complete ;
Figure 2 is a plan of the same, with the cover of the filter removed;
Figure 3 is a detail plan and section of the felt, through which the filtering is
effected; and Figure 4 is a plan and section of the grating which supports the
felt or filtering medium.
The liquid to be filtered is introduced into the vessel a through the openings
bor, and the force pump A is set to work, so as to force the liquid into the
interior of the filtering vessel B, and as the compression of the liquid is main-
tained the latter is forced through the filtering medium c, which consists of a

page_text: layer of felt or wood, or of cotton, wool, silk, or linen cloth, or other good
filtering material. The filtered liquid runs into the receiver d, whence it is
drawn off by the pipe and stop-cock e. When foul the filtering medium is
removed and replaced by a clean one, for which purpose the man-hole door or
cover on the filtering vessel is removed.
Having now described and particularly ascertained the nature of the said
Invention, and the manner in which the same is or may be used or carried
into effect, I would observe in conclusion that what I consider to be novel
and original, and therefore claim as the Invention secured to me by the herein-
before in part recited Letters Patent, is,―
First, the peculiar mode of filtering under pressure, and expressing oils and
liquids generally, as herein-before described.
Second, the general construction, arrangement, and combination of appa-
ratus, whereby liquids may be filtered under pressure, as hercin-before
described.
In witness whereof, I, the said John Henry Johnson, have hereunto
set my hand and seal, this Twenty-first day of October, One thousand
eight hundred and sixty-three.
J. HENRY JOHNSON. (L.s.)
