IMPROVEMENTS IN THE MEANS OR APPARATUS EMPLOYED IN COMPRESSING OIL SEEDS AND OTHER SUBSTANCES INTO CAKES
Year: 1880

page_text: LETTERS PATENT to Henry Frederick Smith, Seed Crusher, Hull, for an
Invention of "IMPROVEMENTS IN THE MEANS OR APPARATUS EMPLOYED IN
COMPRESSING OIL SEEDS AND OTHER SUBSTANCES INTO CAKES."
PROVISIONAL SPECIFICATION left by the said Henry Frederick Smith at
the Office of the Commissioners of Patents on the 11th February 1880.
HENRY FREDERICK SMITH, Seed Crusher, Hull. "IMPROVEMENTS IN THE MEANS
OR APPARATUS EMPLOYED IN COMPRESSING OIL SEEDS AND OTHER SUBSTANCES INTO
CAKES,"
The Invention is one for improved means, appliances, or apparatus employed in
the making of cakes from oil seeds and other substances by the use of a cylinder
or other shaped vessel, which may or may not be steam jacketed, and in which
cylinder or other shaped vessel a ram, worked by hydraulic or other power, com-
presses the substance to be operated upon.
The vessel is fed at one end, and the substance to be pressed is divided into
wished for proportions by the means of metal or other plates. The pressure is
obtained by the ram pressing the material against a previously fixed moveable
head or end to the cylinder or other vessel by the removal of the moveable
head or end, and through the action of the hydraulic or other power.

an Order of the Lord Chancellor, filed by the said Henry Frederick Smith in
the Great Seal Patent Office on the 8th October 1880:
HENRY FREDERICK SMITH, Seed Crusher, Hull. "IMPROVEMENTS IN THE MEANS
OR APPARATUS EMPLOYED IN COMPRESSING OIL SEEDS AND OTHER SUBSTANCES INTO
CAKES."
The Invention is one for improved means, appliances, or apparatus employed in
the making of cakes from oil seeds and other substances by the use of a cylinder
or other shaped vessel (which may or may not be steam jacketed), and in which
cylinder or other shaped vessel a ram, worked by hydraulic or other power, com-
presses the substances to be operated upon.
The vessel is fed at one end, and the substance to be pressed is divided into
wished for proportions by means of metal or other plates.
The pressure is obtained by the ram pressing the material against a previously
fixed moveable head or end to the cylinder or other vessel. The cakes are liberated
from the cylinder or other vessel by the removal of the moveable head or end
through the action of the hydraulic or other power.
My Invention will be clearly understood by reference to the annexed Drawings,
in which Figure 1 shows a seed press with the cylinder in section, and apparatus
used in connection, for filling the seed into the cylinder or other shaped vessel, and
for lowering the ram during the filling.
Figure 2 is a side elevation of the press, and Figure 3 a plan of same.
A is the cylinder or other shaped vessel mounted upon the collar B of the
barrel C, and held by the uprights D, D, which form the stays or bolts from the
collar B to the fixed press head E. This cylinder is open at top and at bottom,
the lower end being occupied by the head F of the ram G, which can be moved up
and down within the cylinder or other shaped vessel, the movement by my Inven-
tion, for either action, being done in stages during the filling or the emptying of
the contents of the cylinder or other shaped vessel.
H is a moveable head or end mounted upon wheels I, I, to run upon rails J, J,
depending from the fixed head E that it may be moved by the hand wheel K and
pinion L engaging into the rack M, with which the moveable head H is furnished.
N is a shoot, within which are two valves or blades P, P, capable of movement
from the outside handles Q, Q, to regulate the descent and the division of the seed
into given quantities to form the desired size of cake to be made. The shoot N
receives its supply of seed from the hopper R, into which the seed or other material
falls from the kettle S when the shutter or flap T is opened by the hand lever and
rod U. The kettle S is provided with blades on a shaft V, whose travel within
the kettle is governed by the bevil gearing W from the over head shaft X or by
other known agent suitable for the purpose.
To the supply pipe a of the water or oil vessel or cistern b I affix a cock or
valve c, which is turned by the handle and rod d when desired either to regulate
the back flow of water or oil from the barrel C to the cistern, while the several
charges of seed or other material are admitted to the cylinder when filling it, or
when the ram bead F has to be lifted in stages to enable the compressed cakes to
be removed singly or otherwise from above the cylinder A.
In the Drawing I have shown the cylinder or other shaped vessel A surrounded
by a hot water or steam jacket, but this forms no part of my Invention, it being
customary in seed compression and oil mills either to heat the seed before they are
sent to the press, or by heating the kettle S in which the seeds are placed pre-
viously to being parcelled off for cakes, or by heating them while in the press.
Having now described the nature of my said Invention and in what manner the
same is to be performed, I declare that I claim,—
The shoot N provided with blades P, P, the moveable head H mounted and

page_text: moving upon rails J, J, and the stop cock c on the pipe a, all arranged, substantially
as shown, to a cylinder or other shaped vessel and press, by which cakes from oil
seeds and other substances are made as described.
Secondly. I claim charging a press, cylinder, or other shaped vessel with distinct
parcels of seed or other substances in a superposed manner from the top thereof and
upon the rain, which is lowered intermittently as each charge is filled in, as
described and substantially as shown by the accompanying Drawings.
In witness whereof, I, the said Henry Frederick Smith, have hereunto set
my hand and seal, this Sixth day of October, in the year of our Lord One
thonsand eight hundred and eighty
