Year: 1870

page_text: LETTERS PATENT to Colin Paget Matthews, of Grantham, in the
County of Lincoln, Brewer, for the Invention of "AN IMPROVED
COMPOUND OR PREPARATION TO BE APPLIED TO THE INSIDES OF CASKS AND
OTHER VESSELS."
Scaled the 4th November 1870, and dated the 4th May 1870..
PROVISIONAL SPECIFICATION left by the said Colin Paget Matthews at
the Office of the Commissioners of Patents, with his Petition, on
the 4th May 1870..
I, COLIN PAGET MATTHEWS, of Grantham, in the County of Lincoln,.
5 Brewer, do hereby declare the nature of the said Invention for "AN
IMPROVED COMPOUND OR PREPARATION TO BE APPLIED TO THE INSIDES OF CASKS AND
OTHER VESSELS," to be as follows:-
:-
The Invention has for its object the manufacture of an improved
compound or preparation to be applied to the insides of casks and other
vessels whereby they are rendered thoroughly air and water tight and.
prevented becoming mouldy, whilst they are more readily cleansed and

page_text: are better adapted for keeping ales and other liquids in a sound
condition. For this purpose I take about six quarts of what is generally
known as r
methylated finish," to which I add about six pounds of
shellac, and when the shellac is thoroughly dissolved I add to the solution
from about two and a half to three pounds of powdered charcoal.
mixture is well roused when using it.
This
The mode in which I apply this preparation to casks is somewhat as.
follows: After thoroughly drying a cask or other vessel I immediately
apply with a paint brush a coating of the preparation to the inside
thereof and let it stand until the next day, when another coat should
be put on and a light applied so as to flame off the spirit. The cask
or other vessel after being washed with hot water will then be ready
for use.
For coating some descriptions of vessels such as squares and vats I
proceed as above but I do not flame off the spirit, and I allow the
vessels to stand for four or five days before using them.
Instead of using methylated finish as before described other suitable
spirit may be employed.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Colin Paget Matthews in the Great Seal Patent
Office on the 4th November 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, COLIN
PAGET MATTHEWS, of Grantham, in the County of Lincoln, Brewer, send
greeting._
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of May, in the year of our
Lord One thousand eight hundred and seventy, in the thirty-third year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Colin Paget Matthews, Her special licence, that I; the
said Colin Paget Matthews, my executors, administrators, and assigns,
or such others as I, the said Colin Paget Matthews, 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, excrcise, and

page_text: vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "AN IMPROVED
COMPOUND OR PREPARATION TO BE APPLIED TO THE INSIDES OF CASKS AND OTHER
VESSELS," upon the condition (amongst others) that I, the said Colin.
Paget Matthews, my executors or administrators, by an instrument
in writing under my or their, or one of their hands and seals, should
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 Letters Patent.
NOW KNOW YE, that I, the said Colin Paget Matthews, 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 thereof, that is to say :-
The Invention has for its object the manufacture of an improved
compound or preparation to be applied to the insides of casks and other
vessels whereby they are rendered thoroughly air and water tight and
prevented becoming mouldy, whilst they are more readily cleansed and
are better adapted for keeping ales and other liquids in a sound condition.
For this purpose I take about one hundred and eight quarts of spirits of
wine, to which I add about one hundred and eight pounds of shellac,
and when the shellac is thoroughly dissolved about sixty pounds of
powdered charcoal are added to the solution. This mixture is well
roused or stirred when using it.
The mode in which I apply this preparation to casks is somewhat as
follows: After thoroughly drying a cask or other vessel I immediately
apply with a paint brush a coating of the preparation to the inside
thereof and let it stand until the next day, when another coat should be
put on and a light applied so as to flame off the spirit. The cask or
other vessel after being washed with hot water will then be ready
for use.
For coating some descriptions of vessels such as squares and vats I
proceed as above but I do not flame off the spirit, and I allow the vessels
to stand for four or five days before using them.
Instead of using spirits of wine as before described "methylated
finish," or other suitable spirit, may be employed and the proportions of
the various ingredients may be modified without departing from the
nature of my Invention.

page_text: I would here remark that I am aware that shellac dissolved in spirit
has before been employed as a varnish or coating for various articles, I
therefore do not claim such mixture or preparation as my Invention,
but what I do claim is, the manufacture of a compound or preparation
consisting of shellac dissolved in any suitable spirit and mixed with
powdered charcoal, in manner and for the purpose substantially as
herein described.
In witness whereof, I; the said Colin Paget Matthews, have here-
unto set my hand and scal, this Thirty-first day of October, in
the year of our Lord One thousand eight hundred and seventy.
Witness,
HENRY MARTIN.
COLIN P. MATTHEWS. (L.S.)
