Year: 1813

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
ADAMS, of Holborn, in the County of Middlesex, Shoe Maker, send greeting.
WHEREAS His most Excellent Majesty King George. the Third, by
His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Seventh day of July, in the fifty-third year of His reign,
did, for Himself, His heirs and successors, give and grant unto me, the said
Robert Adams, His especial licence that I, the said Robert Adams, my exors,
adiors, and assigns, or such others as I, the said Robert Adams, my exors,
admiors, 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 "A NEW AND IM-
PROVED METHOD OF PREPARING BLACKING, WHEREBY A HIGHER POLISH IS GIVEN,
AND THE LEATHER BETTER PRESERVED, THAN BY ANY HITHERTO KNOWN;" in which
said Letters Patent there is contained a proviso obliging me, the said Robert
Adams, by an instrument in writing under my hand and seal, particularly to
describe and ascertain the nature of my said Invention, and in what manner
the same is to be performed, and to cause the same to be enrolled in His
Majesty's High Court of Chancery within two calendar months next and
immediately after the date of the said 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
Robert Adams, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, is described and ascertained
in the following explanation thereof (that is to say):—

page_text: In order to make forty gallons of blacking, take forty gallons of vinegar,
commonly known by the number eighteen, ninety pounds of ivory black, three
gallons of sweet oil, wine measure, twenty-eight pounds of raw moist sugar,
eighteen pounds of oil of. vitriol, and twenty-six ounces of gum arabic, and
procure a tub with a tin strainer fixed under its lid or cover nearly of the
same size of the lid and full of small holes, and with a hole in the lid suffi-
ciently large to admit the pouring in of the liquid ingredients, for which
purpose a funnel may be used if required. Put. the ivory black, the sugar,
the sweet oil, and four gallons of vinegar into the tub, and make them into a
thin paste, then apply half the oil of vitriol through the lid and strainer, and
after letting it stand between five and ten minutes pour through the strainer
about two gallons more of the vinegar, then take off the lid, and gradually
pour in the remainder of the vinegar, keeping the whole continually on the stir
till all the vinegar is used. It. being thus well stirred, put on the cover and
pour in the remainder of the oil of vitroil through the strainer; then pour it
into a copper, put in the gum arabic, and let the whole boil, and when it
begins to boil it is fit to be drawn off, and when cold to be bottled, but while
being bottled should be constantly stirred. To make a less quantity than
forty gallons, a proportional part of the above ingredients to the quantity
required should be used in the same manner.
In witness whereof, I,, the said Robert Adams, have hereunto set my
hand and seal, the Seventh day of September, in the year of our
Lord One thousand eight hundred and thirteen.
