page_text: LETTERS PATENT to William Lomas Joy, of Leeds, in the County of
York, Seed Crusher, for the Invention of "IMPROVEMENTS IN THE
METHOD OF CHARGING OIL SEED PRESSES & THE APPARATUS AND ENVELOPES
THEREIN EMPLOYED.”
ealed the 19th May 1871, and dated the 24th November 1870.
PROVISIONAL SPECIFICATION left by the said William Lomas Joy
at the Office of the Commissioners of Patents, with his Petition,
on the 24th November 1870.
I, WILLIAM LOMAS JOY, of Leeds, in the County of York, Seed
Crusher, do hereby declare the nature of the said Invention for “Im-
PROVEMENTS IN THE METHOD OF CHARGING OIL SEED PRESSES & THE APPARATUS.
AND ENVELOPES THEREIN EMPLOYED," to be as follows:-
My Invention consists of a new. method of charging the boxes of oil
presses and the apparatus necessary for the operation, and is as follows:
-Alongside or near the kettle door I arrange a box of the form and size
of the press box. On the bottom of this box I place a plate of sheet
metal or other substance, described in Specification of Patent No. 315,
2nd February 1869, granted to David Joy, and called a charging plate,

page_text: and on this I place one-half of my envelope of woollen or like material,
and then fill with seed in such requisite quantity to make the cake, the
other leaf of my envelope is then laid over the top of the seed, and a
plate or lid of the size of the box is brought down upon the seed by
mechanical or other means, giving such requisite pressure as will solidify
the seed to enable it to be lift or carried on the charging plate from
this box into the press, after which the charging plate is withdrawn and
the same operation repeated for the other presses.
By this method I am enabled to dispense with the use of the ordinary
bags and envelopes hitherto in use, and in place of them I use my
envelope which is made of woollen or liko material, the edge of which
envelope is doubled up or otherwise thickened so as to prevent cutting
and to form the edge of the cake."
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Lomas. Joy in the Great Seal Patent
Office on the 22nd May 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
LOMAS JOY, of Leeds, in the County of York, Seed Crusher, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fourth day of November, in the
year of our Lord One thousand eight hundred and seventy, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said William Lomas Joy, Her special licence
that I, the said William Lomas Joy, my executors, administrators, and
assigns, or such others as I, the said William Lomas Joy, 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 Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
THE METHOD OF CHARGING OIL SEED PRESSES AND THE APPARATUS AND ENVELOPES
THEREIN EMPLOYED," upon the condition (amongst others) that I, the said
William Lomas Joy, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should

page_text: 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 Seal Patent Office within six calendar months
next and immediately after the date of the said Lotters Patent.
NOW KNOW YE, that I, the said William Lomas Joy, 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 (that is to say) :-
In carrying out my Invention I add to the seed kettles a box (which
by way of distinction I call a measuring box) of the size and form of
the present press box, and in such a position as to be easily filled from
the kettle, and conveniently arranged with regard to the measuring
box a lid or a frame is placed, which may be brought down by machinery
or hand, or the lid or frame may be dispensed with, and merely a block
or bar made use of to compress or consolidate the seed in the measuring
box.
Instead of using the ordinary bags I form a wrapper similar in shape
to the ordinary hairs joined either at the broad or narrow end, the sides
being thickened either by a selvedge, or a cord or piping, or other
material inserted or worked in, so as to form a sort of cushion at the
edges of the wrapper to prevent cutting and form the edges of the
cake.
.
The process is as follows:-At the bottom of the measuring box I
place a plate of metal or other suitable material as described in Speci-
fication of Patent No. 315, dated February 2nd, 1869, granted to David
Joy, and called a charging plate, upon this plate I lay half my wrapper,
I then fill the measuring box with seed from the kettle, and then lay
over the sced the other half of my wrapper, and after this apply either
manual or mechanical pressure to solidify the seed (or other material)
sufficiently to be removed from the measuring box and carried into the
press box for further or final pressure, the charging plate having been
previously withdrawn.
Having now set forth and explained my said Invention and the
manner in which it is to be carried out, I wish it to be understood that
what I claim is, the filling of the oil seed or other material (to be
pressed) into the above-described measuring box, and there solidifying

page_text: it so as to carry it into the hydraulic presses. And the use of the above
described wrapper instead of the ordinary bags and hairs.
In witness whereof, I, the said William Lomas Joy, have here-
unto set my hand and seal, this Eighteenth day of May, in
the year of our Lord One thousand eight hundred and seventy-
one:
WILLIAM LOMAS JOY. (L.S.).
