Year: 1786

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, J, JAMES
BELL, of Battersea, in the County of Surry, Malt Distiller, send greeting.
WHEREAS His most Excellent Majesty King George the Third, by His
Letters Patent under the Great Seal of Great Britain, bearing date the
Thirty-first day of January, in the twenty-sixth year of His reign, did give
and grant unto me, the said James Bell, my exors, adññiors, and assigns, His
special licence, full power, sole privilege and authority, that I, the said James
Bell, my exors, adñiors, and assigns, during the terin of fourteen years therein
expressed, should and lawfully might make, use, exercise, and vend my
Invention of " MAKING, PROM THE REFUSE MALT WASH AFTER DISTILLATION,
COMMONLY CALLED SPENT WASH, A VEGETABLE ACID OR VINEGAR, FOR THE PURPOSES
OF TRADES AND MANUFACTURES," within that part of His Kingdom of Great
Britain called England, His Dominion of Wales, and Town of Berwick-
upon-Tweed; in which said recited Letters Patent is a proviso obliging me,
by an instrument under my hand and seal, to cause a particular description
of the nature of my said Invention, and the manner in which the same is to
be performed, to be inrolled in His Majesty's High Court of Chancery
within one calendar month next after the date of the said Letters Patent,
as by the said recited Letters Patent, relation being thereunto had, may
more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
James Bell, do hereby declare that the nature of my said Invention, and the

page_text: manner in which the same is to be performed, is herein-after particularly
described and ascertained; and the converting of the refuse malt or molasses
wash after distillation, commonly called spent wash, into a vegetable acid or
vinegar, for the purposes of trades and manufactures, is effected after the
following manner (that is to say):-
The wash, from its having long endured so great a degree of heat as is
necessary for a perfect distillation of the spirit, becomes subject to a putrid
fermentation, which is known by a thick scum with a very offensive smell,
always taking place in proportion to the length of time kept, and by degrees
becoming wholly putrid. To change this tendency, and make it commence an
acetous fermentation, it is necessary to stir up the lee from the bottom, and
frequently to break and immerse the scum in the body of the liquor, and to
repeatedly or daily destroy it till the offensive putrid scum is changed into a
light mouldy film, then the stirring need not be so often renewed. This process
must be continued till the liquor is changed sufficiently sharp, and gains
transparency; but it is accelerated by addition of oil of vitriol and dilution
with warm or cold water if the wash be originally strong or home consumption
wash. If it is made from weak or exportation wash, little or no water need
be added, only oil of vitriol. It may be changed either in a close cask, or in a
vessel to which the air has free access. It is intended to be applied to the
uses hereafter mentioned (that is to say):-For the making distilled vinegar,
vegetable acid spirit, concentrated acid spirit, and acetum radicatum; for the
chrystalization of all the perfect metals and imperfect metals that will form
chrystals with a vegetable acid spirit, or concentrated acid spirit; and for
making extracts from these metals that will or will not form chrystals with it;
for the converting of lead into ceruse or white lead by the vegetable acid or
vinegar for making lac virginale, and vitriol or sugar of lead, with the
vegetable acid spirit, and for making all other preparations of lead obtained
by vegetable acid or vinegar, or of the spirit or concentrated acid spirit of the
same; for the making or preparing any colours with the vegetable acid or
spirit, or concentrated acid spirit, such as verdegrease, or ærugo of copper, or
prepared verdegrease, or chyrstals of copper, or ærugo of iron, or of any other
metal used for making of colours; for the fixing or setting any dye or colour
extracted or made from vegetable, mineral, or animal substances; for making of
salt of vinegar, fixed or volatile, and for neutralizing of fixed salts; for cutting
of isinglass, or making of finings for ales, porter, or any kind of beer, with the
vinegar or vegetable acid, and for chymical tests, uses, and experiments; and
any purpose to which the vegetable acid, or vinegar, or distilled vinegar,
for
;
