AN IMPROVED METHOD OF MANUFACTURING SALT
Year: 1824

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
AINSWORTH JUMP, of Middlewich, in the County of Chester, Salt Proprietor,
and WILLIAM COURT, of Manor Hall, in the County of Chester, Esquire, send
greeting.
WHEREAS His most Gracious Majesty King George the Fourth, by His
Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Fifteenth day of June, in the fifth year of His reign, did,
for Himself, His heirs and successors, give and grant unto us, the said
William Ainsworth Jump and William Court, His especial licence that we, the
said William Ainsworth Jump and William Court, our executors, administrators,
and assigns, or such others as we, the said William Ainsworth Jump and
William Court, our executors, administrators, 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;" in which said
Letters Patent there is contained a proviso obliging us, the said William
Ainsworth Jump and William Court, by an instrument in writing under our
hands and seals, particularly to describe and ascertain the nature of our 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.

page_text: NOW KNOW YE, that in compliance with the said proviso, we, the said
William Ainsworth Jump and William Court, do hereby declare that the
nature of our said Invention of An Improved Method of Manufacturing Salt
consists in gradually charging the salt pan with brine heated in metallic pipes,
tubes, or vessels, fixed underneath tho pans in such a manner that the brine
flowing through them may be heated by the same fires which are employed to
evaporate the brine in the paus.
In using this Invention, the pans are first supplied with cold brine, to the
depth of two or three inches, and the pipes being also filled with cold brine, the
fires are lighted, and a gradual flow of brine is continued from the reservoir to
the pans through the pipes; and the brine, being sufficiently heated in its
progress, is, by means of a regulating cock, made to flow in such quantities as
gradually and sufficiently to supply the pans, and this process is continued till
it becomes necessary to pick the pan, the salt made being from time to time
taken out, as may be convenient.
And in further compliance with the said proviso, we, the said William
Ainsworth Jump and William Court, do hereby also describe one mode of
performing our said Invention by the following description thereof, reference
being had to the Drawing and Figures thereof hereunto annexed, that is
to say :-
Figure 1 in the Drawing represents a longitudinal section of the common
salt pan, fireplace, and chimney, together with a transverse section of one of
the metallic tubes or vessels employed in our said Invention; Figure 2 a
ground plan of the said pan, fireplace, and chimney, with the position of the
said tube; and Figure 3 a perspective representation of the application of our
said Invention. Letters A indicate the salt pan; B, the fireplaces; C, the
ashpits; D, the walls supporting the pan bottom; and E, the chimney; the
whole of which parts, that is to say, the salt pans, fireplaces, ashpits, walls
supporting the pan bottom, and chimney, are the same as are now in ordinary
use. S are pipes in which, in our Invention, the brine is heated in its way
from the feed-pipe F of the reservoir into the pan at G. H is the regulating
cock, by which the quantity of brine made to flow through the pipe S is
determined.
We have found that one pipe of iron, three inches in the bore, passing
through perforations in the walls that support the pan bottom transversely, to
be sufficient for the manufacturing salt in, or for supplying a salt pan twenty-
eight feet long, twenty-four feet broad, and thirteen inches deep; but we do
not limit our said Invention to the use of one pipe or tube only for charging
the pan, or to placing that pipe, tube, or vessel in any particular direction

page_text: under the pan. But we claim as our Invention the above method of gradually
charging the salt pan with brine heated as above described.
In witness whereof, we, the said William Ainsworth Jump and William
Court, have hereunto set our hands and seals, the Thirteenth day of
August, in the year of our Lord One thousand eight hundred and
twenty-four.
