AN IMPROVED METHOD OF MANUFACTURING SALT FROM BRINE;
Year: 1841

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
GARNETT, Merchant, and JOSEPH WILLIAMS, Manufacturing Chemist, both of
Liverpool, in the County of Lancaster, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Ninth day of November, in the fifth year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto us, the said
John Garnett and Joseph Williams, Her especial licence, full power, sole
privilege and authority, that we, the said John Garnett and Joseph Williams,
our exors, admors, and assigns, or such others as we, the said John Garnett
and Joseph Williams, our exors, adññors, 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, our
Invention of "AN IMPROVED METHOD OF MANUFACTURING SALT FROM BRINE;" in
which said Letters Patent is contained a proviso that we, the said John
Garnett and Joseph Williams, or one of us, shall cause a particular description
of the nature of our said Invention, and in what manner the same is to be
performed, to be inrolled in Her said Majesty High Court of Chancery within
six calendar months next and immediately after the date of the said in part

page_text: 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, we, the said
John Garnett and Joseph Williams, do hereby declare the nature of our
said Invention, and the manner in which the same is to be performed, aro
fully described and ascertained in and by the following description thereof,
reference being had to the Drawings hereunto annexed, and to the figures
and letters marked thereon, that is to say:-
The nature of our improvements in making salt from brine is as follows;
that is to say, instead of applying heat to the bottom or sides of the pan con-
taining the brine to be evaporated, we use pipes or tubes of metal passing
nearly horizontally through the fluid, and through these pipes we pass steam
from any suitable steam boiler or generator, for the purpose of conveying
heat to the brine. This arrangement admits of the cistern or pan containing
the brine being made of slabs of stone, slate, earthenware, wood, metal, or
any other similar substances, preferring those that are bad conductors of heat,
and on which the salt may be deposited without injury.
DESCRIPTION OF THE DRAWING.
The Drawing shews a pan for evaporating brine; a, a, being a steam pipe
through which steam is passed, in order to heat the brinc in the pan. The
arrangement above given is for making the coarser grain salt; if the fine grain
salt be required to be made, then a larger extent of heating surface of the
pipes will be used, in order to raise the temperature of the brine and keep it
at a boiling temperature.
We would remark that the shape of the pan may be varied, and also tho
size and direction of the steam pipe employed. And we wish it to be under-
stood that we are aware that triangular flues or chambers have been proposed
to be used, and to have steam passed through them when contained in salt
pans, but we believe without success, we therefore do not claim the use of
chambers or vessels with three flat surfaces; but what we claim is, the mode
of heating brine in the manufacture of salt, by applying cylindrical or curved
surfaced pipes or tubes for conveying steam through brine.
In witness whereof, we, the said John Garnett and Joseph Williams,
have hereunto set our hands and seals, this Sixth day of May, in the
year of our Lord One thousand eight hundred and forty-two.
