Year: 1835

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
BIRD, of Birmingham, in the County of Warwick, Gentleman, send greeting.
WHEREAS His present most Excellent Majesty King William the
Fourth, by His Letters Patent under the Great Seal of Great Britain,
bearing date at Westminster, the Fifteenth day of October, in the sixth year
of His reign, did, for Himself, His heirs and successors, give and grant unto
me, the said John Bird, His especial license, full power, sole privilege and
authority, that I, the said John Bird, my exors, adñiors, or assigns, or such
others as I or they should at any time agree with, and no others, from time to
time and at all times during the term of fourteen years, should and lawfully
might mako, use, exercise, and vend, within England, Wales, and the Town
of Berwick-upon-Tweed, my Invention of "Ax IMPROVED METHOD OF MAKING
AND COMPOUNDING PRINTERS' INK, PAINTS, AND OTHER PIGMENTS;" in which said
Letters Patent is contained a proviso, that I, the said John Bird, shall cause
a particular description of the nature of my said Invention, and in what
manner the same is to be performed, to be enrolled in His said Majesty's
High Court of Chancery within six calendar months 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.
NOW KNOW YE, that in compliance with the said proviso, I, the said
John Bird, do hereby declare that the nature of my said Invention, and

page_text: the manner in which the same is to be performed, is described and ascertained
as follows (that is to say) :-
:-
My improved method of making and compounding printers' ink, paints, and
other pigments, is as follows:-I take a certain portion of mineral earth or
matter found in great abundance on my estate, at Dinas Mowddwy, in
Merionethshire, in North Wales, and other places, which mineral earth or
matter I first wash clean from every portion of slate or other debris, and
which after such washing becomes a very fine black impalpable powder, if
dried, or a very fine paste, if wet. This mineral earth or matter is a black
deposit, and is a compound prepared by nature, consisting of the following
substances, and in the following proportions, or some like proportions
(namely): Silicia, forty-six; alumina, forty-two; and coaly matter, twelve;
In order to make printers' ink, I take as large a portion of this prepared
compound as I deem necessary, and mix and grind it up with boiled oil or
prepared oil usually used in the making of inks, which, when so prepared, is
my improved method of making and compounding printers' ink.
To make ink used in copper-plate printing, I adopt the method now in use,
substituting the above-mentioned compound in lieu of Francfort: black, or
what is usually designated by that name. I then, in order to make and
compound paints and other pigments, take, in those proportions I find
necessary, the above matter, and mix and compound it with oils, spirits, or
any substance requisite for making paints and other pigments, under which
last description I include the making of blacking.
In the manufacture of ink, blacking, paint, or other pigments, I do not
confine myself to any particular quantities of the ingredients above-mentioned,
but take any quantities thereof which are found most desirable...
I claim no exclusive privilege for the use of any other. matter in making
and compounding inks, paints, or other pigments, except the use of the
compound above described; and for the use of the said compound, and for
mixing it in any way, or in any proportion convenient for the making ink,
paints, and other pigments, I do hereby claim the exclusive.privilege.
In witness whereof, I, the said John Bird, have hereunto set my hand
and seal, this Twelfth day of April, in the year of our Lord One
thousand eight hundred and thirty-six.
