CERTAIN IMPROVEMENTS IN THE MANUFACTURE OF OIL AND SEED CAKE
Year: 1841

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HUTCHINSON, of Sutton-on-Trent, in the County of Nottingham, Seed Crusher,
send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Fifth day of April, in the fourth year of Her reign, did, for
Herself, Her heirs and successors, give and grant unto me, the said William
Hutchinson, my exors, adññors, and assigns, Her especial licence, full power,
sole privilege and authority, that I, the said William Hutchinson, my exors,
admors, and assigns, and such others as I, the said William Hutchinson, my
exors, admors, or assigns, should at any time agree with, and no others, from
time to time and at all times hereafter during the term of years therein
expressed, should and lawfully might make, use, exercise, and vend, within
that part of Her said Majesty's United Kingdom of Great Britain and
Ireland called England, Her Dominion of Wales, and Town of Berwick-
upon-Tweed, my Invention of "CERTAIN IMPROVEMENTS IN THE MANUFACTURE
OF OIL AND SEED CAKE;" in which said Letters Patent is contained a proviso
that I, the said William Hutchinson, shall cause a particular description of
the nature of my said Invention, and the manner in which the same is to be
performed, under my hand and seal, to be inrolled in Her said Majesty's
High Court of Chancery, within six calendar mouths next and immediately
after the date of the said in part recited Letters Patent, as in and by the
same, reference being thereunto had, will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
William Hutchinson, do hereby declare that the nature of my said Invention,
and the manner in which the same is to be performed, are fully set forth in
and by the following description thereof, that is to say :-
My said improvements in the manufacture of oil and seed cake consist
in the manufacture of oil cakes from barley, beans, peas, tares, wheat,
oats, or other grain or pulse, combined with a certain quantity of linseed.
The process which I adopt is as follows:-I first pass the barley or other
grain or pulse through a riddle, in order to free it from any gravel,
sand, or other rubbish which may happen to be mixed with it; I then
grind twelve quarters, say of barley, to meal, to which I add nine quarters
of linseed (preferring the best), previously crushed by passing it between
rollers. When..well mixed, these ingredients are ground together under
vertical stones until they are reduced to a fine flour, which is then placed in a
kettle and heated to about two hundred and twelve degrees by means of steam.
While in this hot state it is removed from the kettles into an ordinary stamper
press and subjected to great pressure, by which all the superfluous oil from the
linseed that is not taken up by the barley is expressed. In carrying out this
process I find that one pair of vertical stones will serve three stamper presses,
producing at the rate of sixteen eight-pound cakes per hour each. If the
barley is ground under millstones before mixing with the linseed, or if both
are passed through separate rollers, and are only crushed before admixture, one
pair of vertical stones will only pulverize the mixed meal fast enough to supply
two stamper presses, producing the before-mentioned quantity per hour. It is
important that the materials should be thoroughly pulverized, otherwise the
oil cake produced is rough in appearance, wants coherence, and is of inferior
quality; the better the barley and linseed are ground together the greater will
be the quantity of oil absorbed by the barley, and the better will be the
feeding qualities of the cake. The process to be followed is the same with
any other kind of grain or pulse; and although I prefer the proportions given
above, I do not confine myself precisely thereto.
What I claim is, the manufacture of oil cakes by the admixture with linseed
of barley, wheat, oats, peas, beans, tares, or other grain or pulse, in the pro-
portions or about the proportions and manner herein-before described. And
such my said Invention being, to the best of my knowledge and belief, entirely
new, and never before used in that part of Her said Majesty's United
Kingdom of Great Britain and Ireland called England, Her Dominion of
Wales, and Town of Berwick-upon-Tweed, I do hereby declare this to be my
Specification of the same, and that I do verily believe this my said Speci-

page_text: fication doth comply in all respects, fully and without reserve or disguise, with
the proviso in the said herein-before in part recited Letters Patent contained;
wherefore I do hereby claim to maintain exclusive right and privilege to my
said Invention.
In witness whereof, I, the said William Hutchinson, have hereunto set
my hand and seal, this Sixteenth day of July, One thousand eight
hundred and forty-one.
