Lake, & Co., Patent Agents, Southampton Buildings, London, for
the Invention of "IMPROVEMENTS IN MOULDS FOR OIL CAKES.”. -A
communication from abroad by Richard McDonald, of Hull, in
the County of York, but now temporarily residing in the United
States of America.

PROVISIONAL SPECIFICATION left by the said William Robert Lake
at the Office of the Commissioners of Patents, with his Petition, on
the 10th May 1873.
I, WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co.
Patent Agents, Southampton Buildings, London, do hereby declaro the
nature of the said Invention for "IMPROVEMENTS IN MOULDS FOR OIL
CAKES," a communication, to be as follows:-
My improvements consist in a novel and peculiarly constructed series
of moulds, which, when filled with finely crushed or ground seed, and
combined and subjected to the action of a hydraulic press, constitute
effectual means by which the oil existing in the said ground or crushed

page_text: seed may be completely extracted therefrom, and the quality of the
residuum or cake will be materially improved.
My said improvements are simple in their construction, application,
and operation.
The moulds are made of metal plates, and I use in combination there-
with canvas laps to separate the pressed cakes from the plates, and to
facilitate their removal therefrom; I also use hair or grass rope flanges
which permit the free exit of the oil existing in the crushed or ground
seed when the same is subjected to pressure.
In the operation of preparing and filling the several moulds with the
crushed seed, and combining them for the press, I place upon the
bottom mould a canvas lap and rope flange, and upon the canvas
lap I place a "former." I then fill the mould with crushed or ground
seed closely packed; then I remove the said “former” and cover the
already partially formed cake with a second canvas lap, and upon this
With this mould the
last layer of canvas I place another mould.
"former" is brought into requisition for a second cake to be made in
the same manner as described for the bottom cake; lastly, a mould with
hair or grass rope flange, but without the canvas laps, is inverted and
placed upon the pile to complete the series.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said William Robert Lake in the Great Seal Patent
Office on the 10th November 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of May, in the year
of our Lord One thousand eight hundred and seventy-three, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Robert Lake, Her special
licence that I, the said William Robert Lake, my executors, adminis-
trators, and assigns, or such others as I, the said William Robert Lake,

page_text: 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 Ircland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
MOULDS FOR OIL CAKES," a communication to me from abroad by Richard
McDonald, of Hull, in the County of York, but now temporarily residing
in the United States of America, upon the condition (amongst others)
that I, the said William Robert Lake, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands
and scals, 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 in the Great Scal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said William Robert Lake, 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
Drawing forming a part of this Specification:-
My improvements consist in a novel and peculiarly constructed scries
of moulds, which, when filled with finely crushed or ground sced, and
combined and subjected to the action of a hydraulic press, constitute
effectual means by which the oil existing in the said ground or crushed
seed may be completely extracted therefrom, and the quality of the
residuum or cako will be materially improved.
The oil imunmomenta am simple in thain annatuation annlination

page_text: Figure 3 shews the "former," which is used only to bring the ground
or crushed seed into the proper form upon or within the moulds in its
preparation for the press.
Figure 4 shews the intermediate or middle mould plate of the scries,
provided also with the aforesaid canvass laps and hair or grass rope
flanges.
The plates which constitute the bottom or top of the several moulds,
according as thoy are used in an upright or inverted position in the
combination, are constructed of metal, usually iron. These plates aro
shown at A in Figures 1, 2, and 4. The canvass laps are shown in the 1
same Figures at B, and the twisted hair or grass rope flanges at C...
The office of the canvass laps is to separate the pressed cakes from
the plates A, and to facilitate their removal therefrom, whilst the hair or
grass rope flanges C permit the free exit of the oil existing in tho
crushed or ground seed when the same is subjected to pressure.
:
The operation of preparing and filling the aforesaid moulds with the
crushed seed, and combining them for the press, is conducted as follows,
that is to say-I take the bottom mould, shewn in Figure 2, and having
placed a canvass lap B upon the bottom and rope flanges thereof, and
upon the said canvass lap tho aforesaid " former," shewn in Figure 3, 1
I fill the mould with crushed or ground seed closely packed; then I
remove the said "former" and cover the already partially formed cake
with the second canvass lap thereon shewn, and upon this last layer of
canvass I place the mould, shown in Figure 4, and with this mould bring
into requisition the "formér" for a second cake, to be made in the same a
manner as described for the bottom cake; lastly, the mould with hair or
grass rope flange, but without the canvass laps, is inverted and placed
upon the "pile" to complete the series. This mould is shewn at the
top of Figure 1, wherein, as herein-before specified, the mould is shewn
as filled and ready for the press.
Experiments have proved that by this Invention more oil can bé
obtained from the crushed seed, and consequently a better quality of
residuum will be produced than has ever been obtained or produced by
any of the moulds as constructed and in general use at the present time;
hence the said Invention will be of great utility not only to the manu-
facturers of seed oils and oil seed cake but to the public in general.

page_text: Having thus described the said Invention, as communicated to me
by my foreign correspondent, and the manner of performing the same,
I wish it understood that I claim,―
First. Moulds formed of metal plates with raised rope flanges, as
herein described for the purpose specified.
Second. Providing oil cake moulds with canvass laps, for the purpose
specified.
In witness whereof, I, the said William Robert Lake, have here-
unto set my hand and scal, this Tenth day of November, in
the year of our Lord One thousand cight hundred and seventy-
three.
