page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
KEMSLEY DAY, of Stratford, in the County of Essex, Hydro Fuze Manufac
turer, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster; the First day of August,
One thousand eight hundred and forty-nine, in the thirteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Richard Kemsley Day, mytexors, admors, and assigns, Her especial
licence, full power, sole privilege and authority, that I, the said Richard
Kemsley Day, my exors, adñors, and assigns, and such others as I, the
said Richard Kemsley Day, my exors, admňors, 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, my Invention of "IMPROVEMENTS IN THE MANUFACTURE OF EMERY PAPER,
EMERY CLOTH, AND OTHER SCOURING FABRICS;" in which said Letters Patent
is contained a proviso that I, the said Richard Kemsley Day, should cause
a particular description of 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 seal, 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

page_text: 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
Richard Kemsley Day, do hereby declare that the nature of my said Invention,
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:-
My Invention consists,―
First, of Manufacturing Emery Paper, Emery Cloth, and other Scouring
Fabrics, by employing in such manufacture waterproof cement.
And, secondly, my Invention consists of causing the paper or fabrics
employed to be coated on both sides with the scouring powder or material.
And in order that my Invention may be most readily carried into effect, I will
proceed to describe the means pursued by me; but I would first remark, that
the cementing materials heretofore employed in this manufacture has been
glue, with other material mixed or dissolved with water, consequently, when
scouring paper or fabrics so made have been subjected to damp, they require
to be dried before being used; and in fact so liable are the present scouring
fabrics to absorb moisture, that it is an almost invariable custom for parties
about to use scouring papers or fabrics first to dry them.
Now, according to the first part of my Invention, in consequence of em-
ploying waterproof cement, the scouring paper or fabric will not be so
prejudicially acted on by moisture. The flexible and waterproof cement em-
ployed may be varied; but I believe the following will be found to be the best
for the purpose of carrying out the first part of my Invention:-I take three
parts by weight of boiled linseed oil, two parts of strong African copal, (I melt
this gum, and pour in the oil, which should be hot,) and to these I add one part
of lac, one part of Venice turpentine, one part of Venetian red, one twentieth
part of Prussian blue, one. twentieth part of litharge, and one part of dissolved
india rubber. I mix these well together, which a process which will readily
be performed by varnish makers and others acquainted with the mixing of such
matters; and in order to render such preparation of-waterproof-cement-to-the-
proper consistency when too thick, a stiff boiled linseed oil is to be mixed
.therewith. This cement is to be spread, evenly over the paper or fabric, and
the emery powder, glass powder, or material is to be applied in like manner
to what has heretofore been the practice when using glue and other material.
And.in carrying out the second part of my Invention I spread the cement
and the scouring matter employed on both sides, the object being to save fabric,
and add to the convenience of use, for there may be a coarser and a finer
surface produced, or, both sides may be of the same character.

page_text: Having thus described the nature of my Invention, and the manner of
performing the same, I would state that I make no claim to the waterproof
cement separately, nor do I confine myself thereto; but what I claim is the
manufacture of emery paper, emery cloth, and other scouring fabrics by
employing waterproof cement.
And, secondly, I claim the making of emery paper, emery cloth, and other
scouring fabrics, by applying the scouring materials on both sides.
In witness whereof, I, the said Richard Kemsley, Day, have hereunto
set my hand and seal, this Thirteenth day of December, in the year
of our Lord One thousand eight hundred and forty-nine.
