PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Concentrating Sulphuric and
other Acids..
I, ELI DYSON, of Vickers Street, Miles Platting, Manchester, in 'the County of
Lancaster, Manager, do hereby declare the nature of this invention 'to be 'as
follows:-
This invention relates to further improvements in the apparatus for which I
obtained Letters Patent No. 17699 of 1893.
I construct the top of the flue upon which the retorts or concentrating vessels rest
of arched blocks flat and horizontal on 'the top surface to obviate the necessity of
wedging the vessels in place. These blocks are preferably formed with a rabbet or
shoulder at one side so that each fits into and rests upon the one next below it and
at the other side are preferably formed with a projecting ledge or its equivalent to
permit of the lip or spout of the vessel overhanging the edge of the vessel next
below it.
I construct the retorts or concentrating vessels (which are preferably of cast iron
lined with a coating of suitable vitreous or acid resisting enamel).with a loose
division plate or diaphragm extending from near the top to within a short distance
of the bottom. This plate may be made of porcelain or other acid resisting
material and may be formed with a groove or otherwise at the sides in which is
placed a cord of asbestos or other suitable packing. The plate may be made flat
or curved as found most desirable and may be placed in the vessel upright or
inclined and in any convenient position. Ledges or the like may be formed in
the interior of the vessel to hold the division plate in the desired position. ".
Instead of or in addition to a loose division plate I may use a distributing
tube or fountain tube shaped so as to receive the liquor flowing from one vessel and
deliver it at or near the bottom of the next and also to prevent the liquor
boiling or splashing over the edge of the vessel or retort. These tubes are made of
acid resisting material and are constructed with one two or more branches or outlets
at some distance from the bottom through which the liquor flows. These branches
or outlets are so placed or arranged as not to be liable to become stopped or choked
by sediment: collecting in the bottom of the vessel. Around the exterior of the
distributing tube at or near its upper edge is attached a perforated plate or its
equivalent of a size approximately corresponding with the diameter of the vessel.
This perforated plate is situated a little below the top edge of the vessel and about
on a level with the spout. It prevents violent ebullition or splashing of the liquor
over the sides of the vessel.
I now arrange the vessels or retorts so that the last three (or more) of the series
are placed below the heating flue or chamber being cut off therefrom by a division

the cooling vessel set in water,

COMME DIMIFICATION
(AMENDED).
Improvements in Apparatus for Concentrating Sulphuric and
other Acids.
I, ELI DYSON, of Vickers Street, Miles - Platting, Manchester, in the County of
Lancaster, Manager, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:―
This invention relates to further improvements in the apparatus for which I
obtained Letters Patent No. 17699 of 1893.
The improvements will be 'fully described with reference to the accompanying
drawings.

indicated by dotted lines).

Fig. 9. Transverse section of same.
The furnace A is constructed as described in the Specification of my 'former
Patent No. 17699 of 1893 with a flue B with arch roof and side flues 6 leading into
the flue or chamber C in which the retorts or concentrating vessels 'D) 'are' placed.
The vessels D are of the same external shape with covers which are connected by
suitable connecting tubes with the condensing tube G.
The roof or top of the flue B I now construct of the blocks E, arched on the
under side, and flat and horizontal on the top surface, to form a support upon which
the vessel D may rest without being wedged to maintain it upright. Each of these
blocks is at the back formed with a rabbet or projection ecurved on top over
which the curved or arched front edge of the one behind it fits any space being
filled with fire clay also at the ends with a corresponding rabbet e¹. Each block is
preferably provided at the front with a projection 2 of the shape shown which
projects over the lower one and rests upon it when in position whereby each is
supported longitudinally by the one below it. The front piece e2 is indented or
curved at e³, at the end where the vessel D does not rest upon it to provide room for
the vessel standing upon the block next below. The blocks E are also made with
apertures through them through which a part of the heated gases from the flue B
can pass into the chamber C.
The retorts or concentrating vessels D are preferably made of cast iron, lined with.
a coating of vitreous or other acid resisting enamel. These I construct with a loose
division; plate or diaphragm d see Fig. 3, extending from near the top to within a

page_text: short distance of the bottom. The division plate or diaphragm is made of porcelain,
glass or other acid resisting material, and provided with a groove d' at the sides in
which is placed a cord of asbestos or other suitable packing to prevent the liquor
from flowing round it and cause the liquor to flow from the top to the bottom at one
side of the plate, and pass under it to the delivery side of the vessel.
The division plate & may be made flat or curved as found most desirable and may
be placed in the vessel D either upright or inclined or other convenient position.
Ledges or the like may be formed in the interior of the vessel D to hold the division
plate d in the desired position.
Instead of the loose division plate d in the vessel 1 to direct the flow of liquor to the
bottom, I may use a distributing or fountain tube F, shaped so as to receive the
liquor flowing from one vessel, and deliver it at or near the bottom of the next, and
also to prevent the liquor boiling or splashing over the edge of the vessel or retort.
The tubes F are made of acid resisting material and are constructed with one two or
more branches or outlets f at some distance from the bottom through which the
liquor flows, see Fig. 3. The branches or outlets f are so placed or arranged as not
to be liable to become stopped or choked by sediment collecting in the bottom of
the vessel. Around the exterior of the distributing tube F, at or near its upper edge
it attached a perforated plate H or its equivalent of a size somewhat less than the
diameter of the vessel D). The perforated plate H is situated a little below the top
edge of the vessel, and about on a level with the spout K. It prevents violent
ebullition or splashing of the liquor over the sides of the vessel.
I now arrange the vessels or retorts D at the lower end outside the chamber C and
construct the chamber C with a partition or wall L, which cuts it off from the last
three or more of the vessels D, so that the liquor therein will gradually cool before
being delivered to the cooling vessels M set in water.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I wish it to be understood
that I am aware of the Specification of Webb's Patent, No. 2,343 A.D. 1891 and
I make no claim to anything described and claimed therein but I declare that
what I claim is:-
1. The improvements in apparatus for concentrating sulphuric and other acid,
substantially
as described.
2. In apparatus for concentrating sulphuric and other acid, the use of blocks E to
form the roof or top of the flue B and to support the concentrating vessels D,
substantially as described and shown.
3. In vessels for concentrating sulphuric and other acid the use of a loose division
plate or diaphragm d placed in the vessel with a packing of asbestos or other
material, substantially as and for the purpose described.
4. In apparatus for concentrating sulphuric or other acid fountain tubes F
provided with one, two or more branches or outlets f at some distance from the
bottom, in combination with a perforated plate H attached at or near its upper
edge, substantially as and for the purpose described.
5. The arrangement and combination of apparatus for concentrating sulphuric
or other acid constructed substantially as described and shown.
