NOAK, of West Bromwich, in the County of Stafford, Colliery Agent, and
JOHN NOAK, of the same place, Engineer, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the First day of June (One thousand eight hundred and forty-
four), in the seventh year of Her reign, did, for Herself, Her. heirs and
successors, give and grant unto us, the said Walter Noak and John Noak, our
exors, adiñors, and assigns, Her especial licence, full power, sole privilege and
authority, that we, the said Walter Noak and John Noak, our exors, adiñors,
and assigns, and such others as we, the said Walter Noak and John Noak,
our exors, adñiors, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter, during the continuance of the
term of years therein mentioned, should and lawfully might make, use, exercise,
and vend, within that part of Her said Majesty's United Kingdom of Great
Britain and Ireland called England, Her Dominion of Wales, and Town of
Berwick-upon-Tweed, our Invention of "IMPROVEMENTS IN THE MANUFACTURE
OF SALT, AND IN APPARATUS TO BE USED THEREIN;" in which said Letters Patent
there is contained a proviso obliging us, the said Walter Noak and John
Noak, or one of us, to particularly describe and ascertain the nature of our
said Invention, and in what manner the same is to be performed, by an instru-
ment in writing under our hands and seals, or under the hand and seal of one
of us, the said Walter Noak and John Noak, and cause the same to be

page_text: inrolled in Her said Majesty's High Court of Chancery within six calendar
months next and immediately after the date of the said in part 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
Walter Noak and John Noak, do hereby declare the nature of our said
Invention, and in what manner the same is to be performed, to be fully
described and set forth in and by the following Statement and Specification
thereof, reference being had to the accompanying Drawings (which we declare
to be and to form part of this our Statement and Specification) by the letters
and numeral figures marked thereon for the purpose of such reference, that
is to say:-
Our Invention consists in, and has reference to, the principles of construc-
tion, and the modes of arrangement of the mechanical parts, and also the
several combinations of the same, as such several matters are herein-after
described and set forth, as regards our application of the same to the objects
set forth and referred to in and by the title of the Letters Patent granted unto
us, the said Walter Noak and John Noak, as herein-before recited. The
particular nature and intention of our said Invention we declare to consist in
forming and constructing for the purposes of the manufacture of salt, with
reference to a more economical and beneficial practical character as regards
its mode of working or operation and the superiority of the product. We
declare that we carry such the particular nature and intention of our said
Invention into practical effect by the mechanical constructions and the
arrangements of mechanical parts, with the combinations of the same with
each other, as the same are described and set forth in the following detailed
Specification thereof, and which has direct reference to the Drawings in the
Figures thereof respectively marked Figure 1,, Figure 2, Figure 3; which
Drawings and Figures, together with such detailed Specification, we declare
truly to set forth and describe the constructions, arrangements, and combina-
tions which we adopt in practice in order to embody and carry our aforesaid
Invention into effect, that is to say :-
The Figure 1 represents a view in front elevation of the arrangement of
the apparatus and machinery in and by which we organise our said Invention,
shewing those portions of the furnaces, boilers, broad and fine salt pans and
feeding pipes, with their modes of fixing, which can be seen in a front view of
the erection of the machinery. The Figure 2 represents the entire arrange-
ment of the same apparatus and machinery, shewing those portions of the
furnaces, boilers, broad and fine salt pans, and feeding pipes, with the setting

page_text: and fixing thereof as far as the same can be seen in a horizontal plan view.
The Figure 3 represents a vertical transversal section of the apparatus and
machinery, as it is shewn in the Figure 2, in a horizontal plan view, and taken
through it at the place and in the direction of the dotted line X, X, of the
Figure 2. The Figure 4 represents a vertical longitudinal section of the
apparatus and machinery as it is shewn in the Figure 2, in a horizontal plan
view, and taken through it at the place and in the direction of the dotted line
Z, Z, of the Figure 2. In the Figures 1, 2, 3, and 4, the same letters of
reference are set on or against the same parts respectively as far as the same
can be seen or are shewn in each Figure.
In the Figure 1, A, A, respectively represent the two fire holes of furnaces
which are placed under a large iron boiler H, in which steam is generated for
the purposes of furnishing the heat required in the process. From these
furnaces, flame, heated air, gases, and smoke are produced, and afterwards
pass through the length of the apparatus and under the pan N (seen in the
Figures 2 and 4). This pan receives the flame, heated air, gases, and smoke,
immediately after their first production, because the fine salt pan requires to
be boiled rapidly. The flame, heated air, gases, and smoke, next pass under
the
pan O (seen in the Figures 2 and 4), placed immediately behind the fine salt
pan N. The pan O is for the purpose of making broad salt. The flame, heated
air, gases, and smoke, passing under the fine salt pan N and the broad salt
pan O, pass thence under a reservoir R in which brine is heated for the regular
supply of the fine and broad salt pans N and O and the side pans L, L. The
flame, heated air, gases, and smoke next pass through the flues F, F (seen in
the Figure 3), heating the stove in the usual manner. In the Figure 1,
B, B, represents the ash pits of the two furnaces, shewn at A, A. On cach
side of the ash pits are placed the air pipes C, C, C, C, and through these
pipes there passes a current of air to the air chambers marked D, D, D
(shewn in the Figures 3 and 4). The chambers D, D, D, are situated on
each side, and between the two furnaces A, A, they are constructed in brick-
work or other suitable material. The heated air then afterwards passes
through the pipes E, E (Figures 2 and 4), and thence by the chambers E*
(Figure 4) to the under part and the sides of the reservoirs R (shewn in the
Figures 1, 2, and 3), and from thence it passes off by an escape pipe S (seen
in Figures 1, 3, and 4). The pipe S is extended in its length in order to
create a brisk draught. I, I, are two sets of pipes arranged in arches over
the furnace fireplaces, and connected with each other and with the boiler H
(the pipes I, I, are seen in the Figure 1). U, U, in the Figures 1, 2, and 3,

page_text: mark the stages on which the workmen stand to draw the salt from the salt
pans, and on these stages it is allowed to drain before it is removed into the
stove. L, L, represent a continuation of double-sided and double-bottomed
pans, for the purpose of making broad salt; the lower plates of the double
bottom, and the outer plates of the sides of these pans are made of iron and
are covered in with any substance which is a good non-conductor of heat,
intended for the reception of steam and heated water as they pass from the
boiler H. The heat from the boiler converts the brine into broad salt, which
is deposited on the upper plates of the double bottom and the inner plates of
the sides of the broad salt pans. The inner pan is composed of lead, iron, or
other suitable material. The upper of the double pans is supported by stay
bars extending from the lower bottom plates of the outer pan and secured to
the side of the pan by bolts. The upper part and the ends of the boiler H
are connected with these double pans, and the heated water and steam is
allowed to pass freely between the two bottoms of the broad salt pans. The
water afterwards returns through the pipes K, K (Figures 1, 2, and 3), to the
boiler E, and this circulation of the heated water is continuous during the
working of the furnace and boiler. G (Figure 1) represents a pipe fixed on
the upper part of the boiler H, and is intended to supply the boiler with
water; its delivery is regulated by the operation of a ball cock in the usual
manner. M, M (Figures 1, 2, and 3), are two waste pipes for the escape of
spare steam from the broad salt pans. P, P, P, in the Figures 1, 2, 3, and 4,
are pipes by which the fine salt pan N, and the broad salt pan O, and the
side pans L, L, are supplied with heated brine from the reservoir R. W, W,
in the Figures 1 and 3, mark the entrances into the stove or drying house.
T, T, in the Figures 1, 2, and 3, mark the stages erected at the sides of the
broad and fine salt pans. The broad salt is placed on these stages to drain,
preparatory to its being thrown through the flooring into the storehouse below.
Having thus described the nature of our Invention, and the manner in
which the same is to be performed and brought into practical effect, we declare
that we claim as of our Invention therein as follows:-
Firstly, the boiler H placed in the front of the fine salt pan N and
connected with the broad salt pans L.
Secondly, the chambers D, and their communicating pipes E leading into
the double bottom and sides of the reservoir R. And,
Thirdly, the mode of applying heated air to the purpose of heating the
brine in the reservoir R, in the manner and under the arrangements herein
described.

page_text: And these claims we make as of our Invention, under the constructions,
mechanical arrangements, and combinations herein described and set forth.
In witness whereof, I, the said Walter Noak, have hereunto set my
hand and seal, this Twenty-eighth day of November, in the year of
our Lord One thousand eight hundred and forty-four.
AND BE IT REMEMBERED, that on the Twenty-eighth day of November,
in the year of our Lord 1844, the aforesaid Walter Noak came before our
said Lady the Queen in Her Chancery, and acknowledged the Specification
aforesaid, and all and every thing therein contained and specified, in form
above written. And also the Specification aforesaid was stamped according
to the tenor of the Statute made for that purpose.
