READ, of Park Terrace, King's Road, Chelsea, in the County of Middlesex,.
Gentleman, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent, under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Twenty-ninth day of
December (One thousand eight hundred and forty-nine), in the thirteenth year.
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said John Read, my exors, admors, and assigns, Her especial licence,
full power, sole privilege and authority, that I, the said John Read,, my exors,
adiñors, and assigns, or such others as I, the said John Read, my exors,
admors, or assigns, should at any time agree with, and no others, from
time to time and at all times during the term of years therein, expressed,
should and lawfully might make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, my Invention of "IMPROVE-
MENTS IN MACHINERY FOR EXTRACTING FLUIDS FROM ANIMAL, VEGETABLE,. AND.
MINERAL SUBSTANCES, AND IN COMPRESSING THE SAME;" in which said Letters
Patent is contained a proviso, that I, the said John Read, shall cause a par-
ticular description of the nature of my said Invention, and the manner in
which the same is to be performed, by an instrument in writing under my
hand and seal, to be inrolled in Her Majesty's High Court of Chancery

page_text: within six calendar months next and immediately after the date of the said
in part recited Letters Patent, as in and by the same, reference being thereunto
had, will more fully and at large appear.
'
NOW KNOW YE, that in compliance with the said proviso, I, the said
John Read, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, are fully described and
ascertained in and by the following statement thereof, reference being had to
the Drawing hereunto annexed, and to the figures and letters marked thereon,
that is to say:-
My Invention consists, first, of improvements in apparatus for extracting
fluids from animal, vegetable, and mineral substances, and in compressing the
same.
And, secondly, my Invention consists of improvements in giving motion by
steam to apparatus used for extracting fluids from animal, vegetable, and
mineral substances, and for compressing the same.
And in order that my Invention may be most fully understood and readily
carried into effect, I will proceed to describe the means pursued by me.
DESCRIPTION OF THE DRAWING.
Figure 1 is an elevation of apparatus and machinery, partly in section
arranged according to my Invention. Figure 2 shows a plan thereof, also
partly in section. A is a horizontal steam engine, fixed to the framing I, I,
the piston rod L of which passes through stuffing boxes on the two end covers
of the cylinder A. On the two ends of the piston rod L are rams M, which
enter what I call "the extracting boxes." The rams are hollow, and the ends
of them are perforated, and they are covered with strong fabric, such as are!
used for filters, so that when they are forced into the extracting boxes, the fluid
in the matters contained in such boxes can flow or filter into the rams, and run
off by suitable passages at the back thereof. The extracting boxes J, J, con-
sist each of two hollow rectangular (or it might be other formed) trunks, the
one fitting within the other, and allowing space between them to receive strong
fabric, with which the inner one is covered or clothed, and the two trunks
are perforated with numerous small holes; hence the fluid expressed at the
sides will flow through such perforations. These extracting boxes are inserted
in strong chambers E, within which they fit, there being grooves or channels
formed within them to allow of the extracted fluid to flow off. G, G, are what
I call resisting blocks, which are hollow, and they have in front openings Q,
in which are placed perforated plates, which, like the rams, are covered with

page_text: filtering material, and the liquid flowing through runs off from the interior of
the resisting blocks. The resisting blocks are slided into position by means of
the levers and connecting rod N, and the resisting blocks are locked in position
against the ends of the chambers E by the latches H, H, taking hold of the
projections on the bars F. The matter to be pressed is supplied into the
chambers E by the hoppers D when the rams are at the end of their motion,
so that when the rams again go forward into the extracting boxes, they will
carry forward the matter to be pressed into those extracting boxes, and com-
press such matter within such boxes and between the rams and the filtering
surfaces at Q. The arrangement of the machinery is such, that one of the
rams will be going into its extracting box at the time the other is moving back,
so that they act alternately in their respective extracting boxes. P is the
steam pipe to supply the engine; K is the piston; B is the slide box; C is
gearing for working the slide vales.
Figure 3 shows a side view and section of one of the chambers E. In
using this machinery, when either of the rams has passed into its extracting
box, and the matters therein have been fully compressed, the latches H are
raised, and the compressed matters driven out of the extracting box by the
further motion of the piston; the piston will then go back; as the matters in
the other extracting box are being compressed, the latches H of the empty box
will be again connected with the bars F, and fresh matters from the hopper
will descend so soon as the ram has gone back far enough to allow such
matters to descend into the chamber E, and in this manner will the chambers
E be used in succession, and owing to the direct action of the steam, the power
will be most conveniently employed.
Having thus described the nature of my Invention, and the manner of per-
forming the same, I would have it understood that I do not confine myself to
the details, as herein shewn and described; but what I claim is,-
First, the employment of rams and end plates Q with filtering surfaces, so
that the fluid contained in the matters may pass through the same.
And, secondly, I claim the employment of the direct action of steam, as
described.
.
In witness whereof, I, the said John Read, have hereunto set my hand
and seal, this Twenty-ninth day of June, in the year of our Lord
One thousand eight hundred and fifty.
