Year: 1838

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME,. I, EDMUND
SHAW, of Fenchurch Street, in the City of London, Stationer.
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 May, in the first year of Her reign, did, for Herself,
Her heirs and successors, give and grant unto me, the said Edmund Shaw,
Her especial license, full power, sole privilege and authority, that I, the said
Edmund Shaw, my exors, adiñňors, and assigns, or such others as I, the said
Edmund Shaw, my exors, admors, or assigns, should at any time agree with,
and no others, from time to time and at all times during the term of years
therein expressed, should and lawfully might make, use, exercise, and vend,
within England, Wales, and the Town of Berwick-upon-Tweed, the Invention.
of "IMPROVEMENTS IN THE MANUFACTURE OF PAPER AND PAPER-BOARD," commu-
nicated to me by a certain Foreigner residing abroad; in which said Letters
Patent is contained a proviso that I, the said Edmund Shaw, shall cause
a particular description of the nature of the said Invention, and in what
manner the same is to be performed, to be inrolled in Her 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
Edmund Shaw, do hereby declare the nature of the Invention as communi-
cated to me from abroad, and the manner in which the same is to be performed,
are fully described and ascertained in and by the following statement thereof,
that is to say:

page_text: The Invention relates to a mode of applying bituminous matters in the
making of paper and paper boards; and in order to give the best information
in my power, I will proceed to describe the process as pursued by me, and
which is also applicable to the sheathing of ships and other useful purposes :-
Take either mineral or vegetable tar, by preference Dantzic tar, which
deprive of its essential oil by distillation, as is well understood; dissolve the
product in a solution of potass by boiling; then put a quantity, depending on
the degree it is desired to have the paper bituminous, into the beating engine
containing the half stuff, in the same manner as smalt or any other material
is added; from the beating engine it is passed into the chest, and is then ready
either for the vat or machine, to be manufactured into paper.
Having thus described the nature of the Invention, and the best manner
I am acquainted with for performing the same, I would remark, that variations
may be made in the processes without departing from the Invention, provided
the main objects thereof be retained. But what I claim as the Invention
secured by the present Letters Patent is, the mode of applying bituminous
matters in the manufacture of paper above described.
In witness whereof, I, the said Edmund Shaw, have hereunto set my
hand and seal, this Third day of November, One thousand eight
hundred and thirty-eight
