page_text: TO ALL TO WHOM THESE PRESENTS. SHALL COME, I, JOHN
DALE, of the Parish of Saint Lukes, in County of Middlesex, Millwright, send
greeting.
WHEREAS His most Excellent Majesty King George the Third did,
by His Letters Patent under the Great Seal of His United Kingdom, bearing
date at Westminster, the Third day of October, in the fifty-seventh year of
His reign, give and grant unto me, the said John Dale, my exors, adiñiors,
and assigns, His especial licence, full power, sole privilego and authority,
that I, the said John Dale, my exors, adññiors, and assigns, should and
lawfully might, during the term of years therein mentioned, make, use,
exercise, and vend, within England, Wales, and the Town of Berwick-upon-
Tweed, my Invention of "THE APPLICATION OF A CERTAIN MATERIAL HITHERTO
UNUSED FOR THAT PURPOSE TO THE MAKING OF ROLLERS OR CYLINDERS OF VARIOUS
DESCRIPTIONS;" in which said Letters Patent is contained a proviso that if I,
the said John Dale, should not particularly describe and ascertain the nature
of my said Invention, and in what manner the same is to be performed, by
an instrument in writing under my hand and scal, and cause the same to be
inrolled in His Majesty's High Court of Chancery within two calendar
months next and immediately after the date of the said Letters Patent, that
then the said Letters Patent, and all liberties and advantages whatsoever
thereby granted, shall utterly cease, determine, and become void, as in and
by the same, relation being thereunto had, may more fully and at large
appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
John Dale, do hereby declare that the nature of my said Invention, and the
manner in which the same is to be performed, are particularly described and
ascertained in and by the following description thereof (that is to say) :-
In the first place I take either linen or cotton rags or paper, or paper
trimmings, spent hops, or hop bines, or any other vegetable substance that
will produce a pulp. I then steam or boil and beat it up into a pulp; I then
convey it into a cylinder or mould perforated full of holes, the shape and
dimensions I want my roll or other articles made in.. I then press it until
all the moisture, as nearly as is possible, is out; I then dry them with fre-
quently pressing to the shape and dimensions required, until it become a solid
body. Should it not then be the exact dimensions required I can either
cut it or turn it to any shape or size, the same as wood. For my large size
calendar or other rolls I prefer making them in pieces for the expedition of
drying and being more convenient to make. I then press them on a spindle
made of sufficient strength to withstand the pressure required, secured on by two
flanches. For pouch boxes, ornamental furniture, and other things of different
descriptions, after the pulp is sufficiently beat and part of the water drained,
I then boil my said pulp up again, adding a small quantity of isinglass or
gum arabec or any other astringent material.
I do not claim as my said Invention the method of making and preparing
the pulp.or the articles I make use of.
In witness whereof, I, the said John Dale, have hereunto set my hand
arid seal, this 'Thirty-first day of October, in the year of our Lord One
