The ram of the press may be made hollow, and provided with an annular
packing so as to fit the cylinder and the water intended to operate the press,
the pressure of which may be obtained either from a natural head or from
a force pump, or both combined, is admitted alternately on opposite sides
of the piston or packing so as to elevate the table or depress it by an
ordinary slide valve or other suitable valvular contrivance. The top of the
hollow ram is closed so that the full area of the ram is presented to the
pressure of the water during the descent of the table, or when exerting its
expressing force upon the substance under treatment, whilst the ascent of
the table is accomplished simply by the pressure exerted above the reduced
area of the annular piston or packing only. This press may be worked
either vertically, horizontally, or at an angle according to the requirements of
the various purposes to which it may be applied.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Robert Geoghegan in the Great Seal Patent Office on the
25th March 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
GEOGHEGAN, of James Street Brewery, in the City of Dublin, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fifth day of September, 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 Robert Geoghegan, Her special license that I, the said Robert Geoghe-
gan, my executors, administrators, and assigns, or such others as I, the said
Robert Geogbegan, my executors, administrators, or assigns, should at any
time agree with, and no others, from time to time and at all times there-
after during the time 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 "IN-
'PROVEMENTS IN MACHINERY OR APPARATUS FOR EXPRESSING LIQUIDS FROM VARIOUS
SUBSTANCES," upon the condition (amongst others) that I, the said Robert
Geoghegan, 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, and
in what manner the same was to be performed, and cause the same to be filed

page_text: LETTERS PATENT to Robert Geoghegan, of James Street Brewery, in
the City of Dublin, for the Invention of "IMPROVEMENTS IN MACHINERY OR.
APPARATUS FOR EXPRESSING LIQUIDS FROM VARIOUS SUBSTANCES."
Sealed the 15th February 1861, and dated the 25th September 1860.
PROVISIONAL SPECIFICATION left by the said Robert Geoghegan at the
Office of the Commissioners of Patents, with his Petition, on the 25th
September 1860.
I, ROBERT GEOGHEGAN, of James Street Brewery, in the City of Dublin,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR EXPRESSING LIQUIDS FROM VARIOUS SUBSTANCES,"
to be as follows:-
This Invention relates to a peculiar construction and arrangement of
machinery or apparatus for expressing liquid from semi-fluid or solid substances
such as barm or yeast, and spent grains, and hops, and consists in the
employment for that purpose of a hydrostatic press in conjunction with a
containing vat or vessel for the reception of a substance to be operated upon,
the table of the press working downwards into the vessel, and expelling the
liquid through suitable escape or drain pipes. The under surface of the table,
and the bottom of the containing vessel, are ribbed, or channelled, and the
substance to be compressed when in a semi-fluid state is contained in canvass
bags or between layers of cloth, and placed between wire gratings, but when

NOW KNOW YE, that I, the said Robert Geoghegan, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, reference being had to the accompanying Drawings and to the
letters and figures marked thereon, that is to say:―
My said Invention relates to a peculiar construction and arrangement of
machinery or apparatus for expressing liquid from semi-fluid or solid substances
such as balm or yeast, and spent grains and hops, potters clay and similar
substances, and consists in the employment for that purpose of a hydrostatic
press, in conjunction with a containing vat or vessel for the reception of the
substance to be operated upon; the table of the press working into the vessel
and expelling the liquid through suitable escape or drain pipes. The surface
of the table and the bottom of the containing vessel are ribbed so as to
increase their strength and the substance to be compressed when in a semi-
fluid state is contained in bags. or between layers of canvass, or other suitable
material and placed between wire gratings; but when the substance is of a
solid nature the canvass or bags may be dispensed with. The ram of the
press may be made hollow and provided with an annular packing so as to fit
the cylinder and the water intended to operate the press, the pressure of which
may be obtained either from a natural head or from a forced pump or both
combined, is admitted alternately on opposite sides of the piston or packing
so as to elevate the table or depress it by an ordinaay slide valve or other
suitable valvular contrivance. The top of the hollow ram is closed so that the
full area of the ram is presented to the pressure of the water during the
descent of the table, or when exerting its expressing force upon the substance
under treatment, whilst the ascent of the table is accomplished simply by the
pressure exerted above the reduced area of the annular piston or packing
only. This press may be worked either vertically, horizontally, or at an angle
according to the requirements of the various purposes to which it may be
applied.
And in order that my 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 both Figures.
Figure 1 of my Drawings represents a vertical section of my improved
apparatus herein-before referred to, and Figure 2, is a corresponding plan and
partial horizontal section of the same.

hollow and provided with an annular packing b, b, fitting the interior of
the cylinder;. C is the pressing table secured to the bottom of the ram, by a
key or other suitable contrivance. The cylinder of the press is fitted on to
a bed plate D, supported by the pillars E, E, which are bolted to a flange on
the edge of the containing vessel F. The Drawing (Figure 1,) represents
the containing vessel filled with substances to be pressed, such substances being
shown as enclosed within canvass bags f, f, each bag being separated from its
neighbour by a wire grating 9. The pressing table is guided in its descent in
to the interior of the vessel F, by suitable hinged and forked guides h, one
of which is shewn, which embrace the pillars E, E. The liquid expressed is
allowed to flow off freely through the drain pipe
vessel F; I, I, are the strengthening ribs, cast on
F, and on the. top surface of the pressing table.
the water to and from the cylinder of the press is regulated by an ordinary
slide valve and ports 1, l, the valve being worked by hand or otherwise by
the aid of a lever H; i is the water inlet pipe, and , the outlet or escape
port. By alternately changing the position of the slide valve it is obvious
that the water may be admitted both above the piston of the ram so as to
force it down with its full power by acting on the entire area of such piston
and below the piston so as to elevate the ram and table, in which latter case
the small annular area of the piston only is acted upon.

Having now described and particularly ascertained the nature of my 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, the general construction
arrangement, and combination of machinery or apparatus, for expressing
liquids from various substances as herein-before described.
.
In witness whereof, I, the said Robert Geoghegan have to this my
Specification, hereunto set my hand and seal, this Twenty-second day
of March One thousand eight hundred and sixty-one.
