Improvements in or connected with Oil Cake and Feed Cake Presses
or the like.
We, JOHN ENOCH, of 11, Cornwall Street, Engineer, and HENRY AYSH HAWKE,
of 50, Clifton Street, Commission Agent, both in Hull, in the County of York-
shire, do hereby declare the nature of this invention to be as follows:-
The object of our invention is to construct oil cake and feed cake presses
or the like so that the operation of producing the oil and the cake can be
performed with much greater rapidity than with existing presses, at the same
time to dispense, not only with the bagging which is so costly a part of the
present process of cake manufacturing, but also with the moulding machines
in which the seed has had to be moulded before being placed in the press,
thereby saving the time hitherto required for the operation of moulding which is
a great consideration.
For the purpose of our invention, we employ a large box or receptacle fixed
preferably at the back of the press, this box being of such a size as to just contain
the required quantity of seed or other material to fill up the spaces between
the press plates and to form the number of cakes to be made at each operation.
This box is divided on one side by small horizontal openings or slots from
the back of the press plates to the inside of such box, just of sufficient size to
allow of the insertion of thin plates or knives which are preferably moved by
worm and worm wheel from the front of the press, the motion being in a hori
zontal direction across the box, thereby dividing the seed or the like therein and
forming partitions between each of which there is just the required amount of
seed to make a cake, the number of the divisions being equal to the number
of cakes to be pressed at one operation.
The aforesaid thin plates, which may be of steel or any other suitable metal
or material, are fixed on an angle plate running the whole length of the press
from the centre of the press head to the centre of the press bottom, and between
each of the thin plates fixed on this angle plate are apertures of the same size
as the plates in the press, and continuing in width just sufficient solid plate to
form when withdrawn a stop against the seed and plate.
At the back of the aforesaid box we employ a number of rods or bars having
turned or flattened ends of the same width and thickness as the cake required,
there being one rod for each cake, each being opposite to one of the recesses
between the press plates, these rods are passed through holes formed in the back
of the box and attached at their outer ends to a frame, crosshead or the like,
which is in turn connected to a hydraulic or other cylinder or cylinders, operated
by means of valves or the like, such cylinder or cylinders being fixed to preferably
the
press columns the bent or flattened ends of the rods act as rams for forcing
the layers of seed between the various press plates.
We employ a vertical solid plate at the front of the press which rests on the
ram plate, and the front of which faces the press plates, this plate works in
slides and moves in an upward direction as the ram rises, this acts as a stop

page_text: against the seed or other material being pressed, it can be taken out to allow
of the removal of the cakes.
The sides of each press plate are provided with slide pieces, through which are
passed plates connected one with the other by means of very fine gauze wire, which
allows the oil to escape but retains the seed; these slide plates are connected
to an eccentric shaft which is provided with levers or the like by means of
which the gauze can be moved so that it is not in the way of the cakes when
they are being withdrawn.
The box or receptacle behind the press which contains the seed or the like
can be automatically fed by a worm or other conveyor direct from the kettle.
The operation is as follows:-The required quantity of seed or the like is fed
into the box or receptacle, the sliding plates or knives are moved by means of
the worm and worm wheel and pass through the slots in the box so dividing the
seed into layers of the thickness required for each cake, the cylinders are set
in motion and actuate the rods which slide within the hopper, their flattened
ends force the layers of seed between the press plates thus charging the press
which can then be set in motion, as soon as the seed is passed into the press
the box is ready for refilling, the process being continued as before described.
Our improvements can be applied to existing presses as well as to new ones.

Improvements in or connected with Oil Cake and Feed Cake Presses
or the like.
We, JOHN ENOCH, of 11, Cornwall Street, Engineer, and HENRY AYSH HAWKE,
of 50, Clifton Street, Commission Agent, both in Hull, in the County of York-
shire, do hereby declare the nature of this invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
The object of our invention is to construct oil cake and feed cake presses
or the like, so that the operation of producing the oil and the cake can be
performed with much greater rapidity than with existing presses, at the same
time to dispense not only with the bagging which is so costly a part of the
present process of cake manufacturing, but also with the moulding machines
in which the seed has had to be moulded before being placed in the press,
thereby saving the time hitherto required for the operation of moulding which is
a great consideration.

page_text: Fig. 6 a plan view and Fig. 7 an end view.
Figs. 4 and 7 are drawn to a larger scale than the other figures.
For the purpose of our invention, we employ a large box or receptacle A fixed
preferably at the back of the press B, this box A being preferably rectangular
and of such a size as to just hold the required quantity of seed or other material
to fill up the spaces between the press plates C, in the press B, and to form the
number of cakes to be made at each operation.
The box A is divided on one side by small horizontal openings or slits D
running the depth of such box in a backward direction, just of sufficient size
to allow of the insertion of thin plates or knives E, which are preferably moved
by worm F and worm wheel G operated by a hand wheel or the like H preferably
at the front of the press, such worm wheel being connected to one end of a
threaded spindle or screw J which has its other end working loosely in a boss
or bearing J on the side of the box A; the motion of these knives or plates being
in a horizontal direction across the box, thereby dividing the seed or the like
therein, and forming partitions between each of which there is just the required
amount of seed to make a cake, the number of the divisions forming layers of
seed equal to the number of cakes to be pressed at one operation.
The aforesaid thin plates or knives E (which may be of steel or any other
suitable metal or material) are fixed on an angle plate or frame K, which runs
nearly the whole depth of the press from the head to the press bottom, and
runs the length of the box A in a backward direction, and between each of the
thin plates E fixed on this angle plate or frame K are apertures or openings L,
(Fig. 4), such openings being in the side K' of the angle plate, which faces the
back of the press, such apertures being about the same size as the spaces between
the plates in the press, and continue in width just a sufficient distance to leave
the remainder of the side of the plate solid to form a stop against the seed
when the angle plate with its knives are drawn out whilst the box A is being
filled, so that during the operation of filling, the seed cannot get in between the
press plates, the solid part of the side K¹ of the knife frame K blocking up the
open part between the box A and the back of the press B, but when the knives E
have cut through the mass of meal in the box A, the apertures L are opposite
the spaces between the press plates C to allow of the layers of meal being passed
through to the press at the proper time.
The threaded spindle J passes through the aforesaid angle plate K, which has
a hole through it tapped with a similar thread to the thread on the spindle J,
as the spindle J is caused to rotate by the worm and worm wheel or the like,
the angle plate K is moved to and from the box A, the knives E passing through
the slits 1) and dividing the meal in such box into layers, the side K¹ of such
angle plate at the same time passing through a vertical opening between the end
of such box and the press B.
At the back of the aforesaid box A, we employ a number of rods or bars M
having turned or flattened ends N of the same width and thickness as the cake
required, there being one rod for each cake each being opposite one of the recesses
between the press plates, and working in the spaces between the knives E when
they have cut the layers of seed; these rods are passed through holes formed in
the back of the box and are attached at their outer ends to a frame, crosshead
or the like O which is in turn connected to a hydraulic or other cylinder or
cylinders P by means of piston rods Q operated by means of valves or the
like R, such cylinder or cylinders P being fixed to preferably the press columns B¹,
the bent or flattened ends of the rods act as rams for forcing the layers of
seed between the various press plates C in the press B.
We employ a vertical solid plate B2 at the front of the press B, which rests
on the ram plate B³ and the front of which faces the press plates, this plate
works in slides B' and moves in an upward direction as the ram rises, this acts
as a stop against the seed or other material being pressed thus preventing it

page_text: escaping at the front of the press, this plate can be taken out to allow of the
removal of the cakes.
In place of the handwheel for moving the knife plate or frame K, and the
valves, cylinders, and piston rods for passing the layers of meal or the like
into the press, we may employ an arrangement of pulleys connected by straps
or the like with ordinary driving shafting, and plungers having racks moved
by toothed wheels as shown at Figs. 5 6 and 7, thus allowing of two or more
presses being coupled together and driven from ordinary shafting. In this
case the hand wheel is dispensed with and a pulley S is attached to the threaded
spinale J instead of a worm wheel G being attached to such spindle.
The worm F is mounted on a cross shaft H provided with pulleys S1, S2, each
set consisting preferably of a fast and a loose pulley, one set of pulleys S¹ for
connecting to the shafting and the other_set S2 for connecting to the pulley S
which operates the knife plate or frame K.
Each set of plungers or rams N for forcing the layers of meal between the
press plates C are provided with racks M, which are moved backward and forward
across the box A by means of toothed wheels G¹ which engage with such racks M,
preferably one wheel for each rack, the series of wheels G¹ being mounted on a
shaft G2 preferably common to them all.
The worm F mounted on the cross shaft H gears with a worm wheel G
mounted on the shaft G2, which takes the toothed wheels G¹, and a clutch T
is employed for lifting the worm wheel G out of contact with the worm F
when it is required to bring the knife plate or frame K forward to cause the
knives to cut through the meal in the box, the worm wheel G only engaging with
the worm F when it is required to give motion to the wheels (which operate
the racks M.
In Figs. 5, 6 and 7 two presses are shown connected together with two sets
of operating mechanism, but by employing one set of mechanism only single
presses can be worked equally as well as two, but any number of presses may
be coupled together and worked by duplicating the parts forming the operating
mechanism, with the exception that the cross shaft H with its pulleys S¹ S²,
worm F, worm wheel G, racks M and toothed wheels G¹ are necessary both for
single presses and where two or more presses are connected and worked in a
batch.
The sides of each press plate are provided with slide pieces C¹ within which
slide auxiliary plates W connected one with the other by means of very fine
gauze wire or the like X which allows the oil to escape, but retains the seed,
these plates W are connected to or placed on an eccentric shaft Y which is
provided with levers or the like Z, such eccentric shaft is preferably passed
through holes W₁ in the plates W so that as the shaft is given a turn by means
of its lever Z the plates W are drawn away from the ordinary press plates C
of which they form the sides, and thus allow of the easy withdrawal of the
cakes.
These plates are formed in twos, each two being joined by the gauze or the
like aforesaid, and being independent of the other sets of two, one set of two
joined plates is opposite to each recess or space at the sides between the ordinary
press plates C, and being supported by the slides C¹ on these press plates C,
they rise and fall with such press plates, the gauze or the like connection acting
as a stop against the seed but allowing of the escape of the oil at the sides.
In place of the plates W having gauze they may have hinges X for joining
them together so that as the ram plate goes up these hinges close and so form
the edges of the cake.
The box or receptacle behind the press which contains the seed or the like,
can be automatically fed by a worm or other conveyor direct from the kettle.
The operation is as follows:-The required quantity of seed or the like is fed
into the box or receptacle A the sliding plates or knives E are moved by means
of the worm F and worm wheel G operating the threaded spindle J and

page_text: pass through the slits D in the box A so dividing the seed into layers of
the thickness required for each cake, the pistons in the cylinders Qor
pulleys S, S1 S2 are set in motion and actuate the rams N which slide within
the hopper and force the layers of seed between the press plates C, thus charging
the press which can then be set in motion, as soon as the seed is passed into
the press the box is ready for refilling, the process being continued as before
described, the eccentric shaft being turned to draw the hinged or connected
plates W away to allow of the withdrawal of the cakes.
Our improvements can be applied to existing presses as well as to new ones.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what
we claim is ;-
1. In oil cake or feed cake presses the employment of a box or hopper such
as A preferably fixed at the back of the press B and having slits or openings D
in it, an angle plate K provided with knives or dividers such as E, and with
