Secretary to the Driffield and East Riding Pure Linseed Cake Company,
Limited, for the Invention of "IMPROVEMENTS IN MACHINERY OR APPARATUS
TO BE EMPLOYED IN PREPARING SEED FOR THE OIL PRESS."
Sealed the 29th November 1878, and dated the 2nd October 1878.
PROVISIONAL SPECIFICATION left by the said Richard Davison at the
Office of the Commissioners of Patents on the 2nd October 1878.
RICHARD DAVISON, of Driffield, in the County of York, Secretary to the Driffield
and East Riding Pure Linseed Cake Company, Limited. "IMPROVEMENTS IN
MACHINERY OR APPARATUS TO BE EMPLOYED IN PREPARING SEED FOR THE OIL
PRESS."
The Invention has for its object improvements in machinery or apparatus to be
employed in preparing seed for the oil press.
According to my Invention I press the seed into the form of cake without the
use of bags preparatory to placing the same in the oil press.
The seed is sufficiently pressed into the proper form of cakes without extracting
the oil, and the cake thus formed is afterwards put into the ordinary hydraulic
press.
For this purpose I preferably employ machinery or apparatus constructed and
operated as follows:-
I provide a bench or table, to which is added a suitable lever, by means of which
side plates are raised which in conjunction with ends attached to such side plates
form a receptacle of the proper size and capacity to hold the quantity of seed
necessary to make a cake of any shape or size. After the receptacle thus formed is
filled with crushed seed the plate with the seed upon it is passed under the head of
[Price 6d.

page_text: a press or ram working from above, then by moving a lever in connection with
suitable valves the lower ram with the plate and seed to be formed into a cake is
caused to fall down within a pressing box, and is followed by the upper ram or
press, which is caused to apply sufficient pressure to press the seed into the proper
form of cakes to be placed in the ordinary hydraulic press.
The rams are preferably operated from an accumulator, so that any desired
number of these machines can be worked from the same power.
When sufficiently pressed, by reversing the lever the upper ram or press is caused
to ascend, as also the lower one with the pressed cake thereon, by which means the
pressed cake is lifted out of the pressing box to be taken away to the hydraulic
presses.

page_text: Figure 1 is a vertical section, Figure 2 is a plan, Figure is a side elevation,
and Figure 4 is a front elevation of machinery or apparatus constructed according
to my Invention, and Figure 5 is a sectional elevation representing a different form
of measuring box or frame to be used with the press.
In Figures 1, 2, 3, and 4, a is a measuring box or frame, which is hinged at a¹ to
brackets b fixed to a bench or table c.
In Figure 5 d is a lever or treadle, which is mounted on an axis of motion at d¹,.
and is connected by links e, e, to the inner ends of levers f, f, mounted on axes of
motion f, f. The outer ends of the levers f. f, are by links g, g, connected to side
plates a² hinged to the bench or table at a³, and which side plates, in conjunction
with ends a attached thereto when in the position shown in the Drawing, form a
receptacle or measuring box of the proper size and capacity to hold the quantity of
seed necessary to make a cake of any desired shape or size.
A plate a is placed in position on the bench or table, the receptacle or measure
is then placed over it, and a piece of loose cloth is placed at the bottom of the
receptacle over the plate, and the cloth brought over the upper edge of the receptacle

page_text: or measure; the latter is then filled with seed from the kettle and the ends of the
cloth folded over the seed.
The measure a is then raised on its hinges, or the side plates a² and ends a¹ are
turned down; the plate with the seed upon it is then passed under the head h¹ of a
ram working in a hydraulic cylinder i and over the head of a ram j working
in a hydraulic cylinder k, suitable guides c¹ being employed to ensure the correct
adjustment of the plate, then by moving a lever in connection with suitable valves
and connections (not shown), the lower ram, with the plate a³ and the seed thereon
to be formed into a cake, is caused to fall down within a pressing box l, and is
simultaneously followed by the upper ram or press h, when by continuing its motion
towards the lower ram or by causing the latter to move towards the upper ram when
within the pressing box it is caused to apply sufficient pressure to press the seed
into the proper form of cakes to be placed in the ordinary hydraulic oil press.
When sufficiently pressed, by reversing the lever and valves, the upper ram or
press his caused to ascend, as also the lower one with the pressed cake thereon, by
which means the pressed cake is lifted out of the pressing box l, to be taken away
to the hydraulic oil presses.
The rams are preferably operated from an accumulator, so that any desired
number of these machines can be worked from the same power.
The measuring frame, instead of being arranged and operated as herein-before
described, may be otherwise arranged and operated, for instance, instead of mounting
a complete measuring box or frame on hinge joint to turn up out of the way, as
shown at Figures 1, 2, 3, and 4, it may be so guided as to work up and down in a
vertical line, in which case it may be counterbalanced so as to enable it to be readily
operated by hand, or it may be operated by a lever or treadle connected thereto, as
will be well understood.
Having thus described the nature of my said Invention, and the mode in which I
carry the same into effect, I would have it understood that I do not claim the
hinged measuring box or frame, as such has been heretofore employed for a like
purpose, but what I do claim is the peculiar construction, arrangement, and mode of
operation of machinery or apparatus to be employed in preparing seed for the oil
press, substantially as shown and described.
In witness whereof, I, the said Richard Davison, have hereunto set my
hand and seal, this Thirty-first day of March, in the year of our Lord
One thousand eight hundred and seventy-nine.
