Year: 1861

page_text: LETTERS PATENT to Jacques Edouard Duyck, of Tutsham Mills, West
Farleigh, in the County of Kent, Gentleman, for the Invention of
"IMPROVEMENTS IN THE EXPRESSION OF OIL FROM CAKE AND SEEDS, AND IN-
APPARATUSES EMPLOYED THEREIN."
Sealed the 11th June 1862, and dated the 14th December 1861.
PROVISIONAL SPECIFICATION left by the said Jacques Edouard Duyck
at the Office of the Commissioners of Patents, with his Petition, on the
14th December 1861. .
I, JACQUES EDOUARD DUYCK, of Tutsham Mills, West Farleigh, in the
County of Kent, Gentleman, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE EXPRESSION OF OIL FROM CAKE AND SEEDS, AND IN
APPARATUSES EMPLOYED THEREIN," to be as follows:-
By the arrangements about to be described I am enabled to double, or
nearly so, the amount of work obtained in a given time from the presses as
now worked.
My Invention consists in constructing plates or frames, which are to be
fixed to leather or other suitable holders, of a series of transverse strips or bars
bolted or rivetted on one side to the leather. These strips are united to two
longitudinal tapering side plates formed so as to admit the edges of the holder
between the two thicknesses of the plates, and with channels, open or closed,
beyond the distance to which the edges of the holder extend; there is also.
space between the leather and the side plates for the oil to run through and
enter the channels. I also employ between every pair of plates, fixed to
holders as aforesaid, a naked plate, that is to say, a plate formed with trans-
verse bars and with conical-channelled sides, as before described. To work.

page_text: with these plates I first put a bag of the material from which the oil is to be
expressed upon one of the plates fixed to the holder, and I place upon the bag
one of my naked plates, I then add upon the naked plate another bag of the
material, and fold over it the other plate attached to the holder. The holder
plates and material are put in the press and the other operations are performed
in the ordinary manner.
My Invention also consists in forming grooves or channels in the sides of
the box or press in which the material is placed to receive its pressure. I
then place against the grooved sides a perforated plate, one on each side, the
perforations in which communicate with or lead into the grooves, and thus
escape is provided at the sides of the box or press for the outlet of such oil as
may be expressed.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Jacques Edouard Duyck in the Great Seal Patent Office on
the 14th June 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JACQUES
EDOUARD DUYCK, of Tutsham Mills, West Farleigh, in the County of Kent,
Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of December, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Jacques Edouard Duyck, Her special licence that I, the said Jacques
Edouard Duyck, my executors, administrators, and assigns, or such others as
I, the said Jacques Edouard Duyck, 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 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 "IM-
PROVEMENTS IN THE EXPRESSION OF OIL FROM CAKE AND SEEDS, AND IN APPARATUSES
EMPLOYED THEREIN," upon the condition (amongst others) that I, the said
Jacques Edouard Duyck, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should parti-
cularly 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.

page_text: NOW KNOW YE, that I, the said Jacques Edouard Duyck, 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 Drawings hereunto
annexed, that is to say:-
By the arrangements about to be described I am enabled to double, or
nearly so, the amount of work obtained in a given time from the presses as
now worked.
My Invention consists in constructing plates or frames, which are to be
fixed to leather or other suitable holders, of a series of transverse strips or bars
bolted or rivetted on one side to the leather. These strips are united to two
longitudinal tapering side plates formed so as to admit the edges of the holder
between the two thicknesses of the plates, and with channels, open or closed,
beyond the distance to which the edges of the holder extend; there is also
space between the leather and the side plates for the oil to run through and
enter the channels. I also employ between every pair of plates, fixed to
holders as aforesaid, a naked plate, that is to say, a plate formed with transverse
bars and with conical channelled sides, as before described.
Figure 1 of the accompanying Drawings is a plan of an apparatus con-
structed according to my. Invention. Two plates, A and B, are shown attached
to their holder, the parts being identical. One description suffices for both.
a, a are the transverse strips or bars of metal rivetted to the leather holder b,
and secured at the sides between longitudinal bars c, c, as best seen in
Figure 2, which is a side elevation of the apparatus shown in plan at Figure 1.
The transverse bars, a detached view of one of which is given at Figure 3, are
made with angle pieces d, d, and are united to or between the longitudinal
bars in such manner that spaces or channels e, e, are left between each bar,
and hence apertures are formed or communication is afforded between the
compartments formed by the transverse bars and the exterior of the apparatus,
and through which part of the oil expressed from the seeds passes. The
transverse bars, instead of being made with angle pieces, may be made
straight, and filling-up pieces may be substituted. The naked plate C is
hinged to the leather holder between the plates A and B, and as seen in
Figure 2. In some cases, that is, when a single cake, instead of two cakes, is
to be made in an apparatus, then the naked plate is dispensed with. In
Figure 1 it is shewn resting on and hiding the plate B. The transverse bars
in the naked plate are made and united to the longitudinal bars in a similar
manner to those described with reference to Figure 1. To work, with these
plates, I first put a bag of the material from which the oil is to be expressed

page_text: upon one of the plates fixed to the holder, and I place upon the bag the naked
plate; I then add upon the naked plate another bag of the material, fold over
it the other plate attached to the holder, and the cover or flap of leather D
over all, as shewn in Figure 4. In hydraulic presses the flap D is dispensed
with and a piece of leather is added, whereby to withdraw the apparatuses
from the press. The holder plates and material are put in the press and the
other operations are performed in the ordinary manner.
Figure 5 is a view in plan of a plate somewhat modified in its construction..
The transverse bars are united to the longitudinal bars, both of which rest on
a metal bed, which is rivetted or otherwise connected to the leather holder as
before. The central, or what was previously called the "naked" plate, is similar
in construction to that just described. The plates are worked and folded as
described with reference to Figure 4..
Figure 6 shews in plan another form of plate to be fixed to the holders by
rivets, as before described.
My Invention also consists in forming grooves or channels in the sides of
the box or press in which the material is placed to receive its pressure. I then
place against the grooved sides a perforated plate, one on each side, the
perforations in which communicate with or lead into the grooves, and thus
escape is provided at the sides of the box or press for the outlet of such oil as s
may be expressed.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim,-
First, the construction of plates or frames, fixed to leather or other suitable
holders, for expressing oil from cake and seeds, substantially in manner herein-
before described and illustrated in the accompanying Drawings.
Second, forming grooves or channels in the sides of the box or press in
which the material is placed to receive its pressure, together with the employ-
ment of perforated plates against the sides of each box or press, as herein-
before described.
In witness whereof, I, the said Jacques Edouard Duyck, have hereunto
set my hand and seal, this Fourteenth day of June, One thousand
eight hundred and sixty-two.
