Year: 1874

page_text: LETTERS PATENT to Cyrus Eskrett, of Hull, in the County of York,
for the Invention of "IMPROVEMENTS IN THE MEANS OR APPARATUS
EMPLOYED IN THE MANUFACTURE OF SEED OR OIL CAKES."
Sealed the 23rd October 1874, and dated the 31st July 1874.
PROVISIONAL SPECIFICATION left by the said Cyrus Eskrott at the
Office of the Commissioners of Patents, with his Petition, on the
31st July 1874.
I, CYRUS ESKRETT, of Hull, in the County of York, do hereby declare
the nature of the said "Invention for "IMPROVEMENTS IN THE MEANS OR
APPARATUS EMPLOYED IN THE MANUFACTURE OF SEED OR OIL CAKES," to be as
follows:-
My Invention has reference to oil or seed cake presses of ordinary
construction, and consists, firstly, in improvements in what is known as
the "filler plate" which I by preference make of wood, though not
necessarily so, as it may also be made of other suitable material. Near

the right and left edges and on the top of the "filler plato
angle iron
flanges are fixed, outsido of which I also provide and fix "edges" that
may be of ordinary construction. I perforate the "filler plate" in such
a manner so as to allow the oil from the cake to pass through it to be
conducted along gutters which are provided on the under side of the 5
wood "filler plate." The "filler plate" being arranged in the above
described manner is placed inside the press box and there firmly
secured. The "filler plate" when formed of wood, which is a bad
conductor of heat, retains the heat in the oil cake, preventing stains
or discolouration of the cake, at the same time allowing the oil to bo 1
more freely pressed therefrom.
"
The next part of my Invention has reference to the "press or cake
plate" which I make of the ordinary shape and of metal, and I so
construct it that it may slide or slip within the herein-before mentioned
angle irons on the "filler plate." The ".cake or presser plate" is corru-
gated at the top, in the hollow parts of which are provided slot holes
wider at the under side of the plate than at the top so as to prevent an
accumulation of seed or thick oil.
My Invention further consists in fixing the angle iron to the presser
or cake plate on which the cake is made instead of on the "filler plate." a
After the cake is made the angle iron is removed from the box along
with the "press or cake plate," leaving the "filler plate" perfectly
clear. The bag containing the seed for the cake is placed on the "press
or cake plate," then placed within the press box and on the top of the
"filler plate" ready for the pressing operation.
By having the above described arrangement of "press or cake plate"
the oil passes more freely away from the cake, moro oil is thereby
obtained, and much less damage done to the seed bags. In the top of
the press box I fix an iron corrugated plate of ordinary construction,
and in order to prevent the heat from passing away from the cake during |
the pressing operation I place on the top of the plate one or more
layers of wood or other suitable bad conductor of heat.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Cyrus Eskrett in the Great Seal Patent Office
on the 30th January 1875,
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CYRUS
ESKRETT, of Hull, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirty-first day of July, in the year
of our Lord Ono thousand eight hundred and seventy-four, in the thirty-
cighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Cyrus Eskrett, Her special licence that
I, the said Cyrus Eskrett, my executors, administrators, and assigns,
or such others as I, the said Cyrus Eskrett, executors, adminis,
trators, 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 Ohannel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN THE MEANS
OR APPARATUS EMPLOYED IN THE MANUFACTURE OF SEED OR OIL CAKES," upon the
condition (amongst others) that I, the said Cyrus Eskrett, my executors
or administrators, by an instrument in writing, under my, or their,
or one of their hands and scals, should particularly describe and ascer-
tain the nature of the said Invention, and in what manner the same
was to be performed, and cause tho samo 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 Oyrus Eskrett, 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, reference being had to the accompanying Drawings
and to the letters of reference marked thereon, that is to say :-
My Invention has reference to oil or seed cake process of ordinary
construction, and consists, firstly, in improvements in what is known as
the "filler plate" which I by preference make of wood, though not
necessarily so, as it may also be made of other suitable material. Near
the right and left edges and on the top of the "filler plate" angle iron

page_text: flanges are fixed, outside of which I also provide and fix "edges” that
may be of ordinary construction. I perforate the "filler plate" in such
a manner so as to allow the oil from the cake to pass through it to be
conducted along gutters which are provided on the under side of the
wood "filler plate." The "filler plate" being arranged in the above
described manner is placed inside the "press box" and thero firmly
secured. The "filler plate" when formed of wood which is a bad con-
ductor of heat retains the heat in the oil cake, preventing stains or
discolouration of the cake, at the same time allowing the oil to be more
freely pressed therefrom.
The next part of my Invention has reference to the press or cako
plate which I make of the ordinary shape and of metal, and I so
construct it that it may slide or slip within the herein-before mentioned
angle irons on the "filler plate." The "cake or presser plate" is corru-
gated at the top, in the hollow parts of which are provided slot holes 1
wider at the under side of the plate than at the top so as to prevent an
accumulation of sced or thick oil.
My Invention further consists in fixing the angle iron to the " pressor
or cake plate" in which the cake is made instead of on tho "filler
plate." After the cake is made the angle iron is removed from the box
along with the "press or cake plate," leaving the "filler plate" perfectly
clear. The bag containing the seed for the cake is placed on the "press
or cake plate" then placed within the “ 'press box," and on the top of
the "filler plate" ready for the pressing operation.
"
By having the above described arrangement of "press or cake plate'
the oil passes more freely away from the cake, more oil is thereby
obtained and much less damage done to the seed bags. In the top of
the "press box" I fix an iron corrugated plate of ordinary construction,
and in order to prevent the heat from passing away from the cake
during the pressing operation I place on the top of the plate one or
more layers of wood or other suitable bad conductors of heat.
In order that my Invention may be more completely understood,
reference is given to the accompanying Sheet of Drawings.
Fig. 1 is a plan of "filler plate" looking on the top; Fig. 2, a plan
of the same looking at the bottom.

page_text: Figs. 4, 5, and 6 show respectively a plan, longitudinal section, and
transverse section of the "filler plate" and "cake or presser plate"
combined.
Fig. 7 shews a modification of the "cake or presser plate;" and
Fig. 8, a modification of the "filler plate." Firstly. I by preference
make the "filler plato" of wood, though not necessarily so. Near to
the right and left edges and on the top of the "filler plate" I provide
the angle iron flanges a; outside these I fix the edges b, which edges b
are of the ordinary construction. I perforate the "filler plate" through
with holes, as shewn at c, to allow the oil to pass from the cake through
it so as to be conducted along the "gutters" d which are provided on
the under side of the "filler plate," as shewn at Fig. 2. The "filler
plate" being constructed in the above described manner is placed inside
the "press box" and there firmly secured in the ordinary manner. The
"filler plato" when formed of wood which is a bad conductor of heat-
retains the heat in the oil cake, preventing stains or discolouration of
the cake, at the samo time allowing the oil to be more freely pressed
therefrom.
The next part of my Invention has reference to the "cake or presser
plato" which I make of the ordinary shape and of metal, as shewn at
Fig. 3. I so construct it that it may slido or slip within the hercin.
before mentioned angle iron a. The "cake or presser plate" is corru-
gated at the top, as shewn at Figs. 3, 4, 5, and 6, in the hollow parts of
which are provided slot holes e wider at the under side than at the top so
as to prevent an accumulation of seed or thick oil.
My Invention further consists in fixing the angle iron on the "presser
or cake plate" instead of on the "filler plate," and is shown at f, Fig. 7.
After the cake is made the angle iron fis removed from the "press box"
along with the "cake or presser plate," leaving the "filler plate"
perfectly clear, as shown at Fig. 8. In order to keep the plates apart
during the pressing operation so that the oil may freely pass away from
betwixt them, I fix either on the top of the "filler plate" with the
angle iron attached, or on the under side of the "presser or cake plate"
the iron rods or bars 7. These rods or bars may when preferred be
fixed in the "press box." Any required number of these rods or bars g
may be employed. Any convenient means may be employed for fixing
the rods or bars 9 in position. The bag containing the seed for the cake
