PROVISIONAL SPECIFICATION.
Improvements in Apparatus Employed for Concentrating Sulphurio
and other Acids.
I, ROBERT WILSON, of 117 Charterhouse Street, London, E.C. in the County
of Middlesex, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in porcelain, glass, or glazed earthenware
vessels, retorts, or receivers employed in the concentration of sulphuric acid and
other liquids, the object being to construct such vessels so that a free and perfect
circulation of the liquid under operation is ensured.
According to this invention, I employ circular porcelain or glazed earthenware
vessels or receivers, each vessel having at one side a vertical conduit or passage
formed by bending a strip of porcelain or glazed earthenware in the shape of a
channel or groove whilst in a plastic condition, to the inside of the vessel. This
strip of porcelain extends about one inch from the bottom of the vessel or retort
to the top, and near the top of the vessel a bib or spout is formed as an outlet for
the acid or liquid to pass into the next vessel: this bib or spout which engages
with the conduit or passage, is placed about one or two inches below the top of the
rim of the vessel, and the outer end of the bib or spout is curved downwards.
When a series of these vessels or receivers are employed for concentrating acid
or liquid by any of the ordinary well known cascade processes, the outer curved
end of the bib or spout is placed over the rim of the next succeeding vessel, and so
on through the series, so that as the acid or liquid passes into the first vessel of
the series, it must rise from the bottom of the conduit or passage, and thence up
to the bib or spout, and pass to the top of the next succeeding vessel, and so on to
the end of the series, and by this means a perfect circulation of the acid or liquid
is ensured, the lighter or weaker acid always being at the top.

Improvements in Apparatus Employed for Concentrating Sulphurio
and other Acids.
1, ROBERT WILSON, of 24 Harrison Street, Gray's Inn Road, London, in the
County of Middlesex, late of 117 Charterhouse Street, London, Engineer, 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 improvements in porcelain, glass, or glazed earthenware
vessels, retorts, or receivers employed in the concentration of sulphuric acid and
other liquids, the object being to construct such vessels so that a free and perfect.
circulation of the liquid under operation is ensured.

page_text: Such being the nature and object of my said invention the following is a
complete description of same, reference being had to the accompanying drawings,
in which
Fig. 1 is a sectional side elevation of the improved vessel for purpose aforesaid.
Fig. 2 is a plan view of Fig. 1.
Fig. 3 is a side elevation of a series of the improved vessels shewn communicating
one with another as when in use.
According to this invention, I employ circular porcelain, or glazed earthenware,
or enamelled metal vessels or receivers I, each vessel 1 having at one side a vertical
conduit or passage 2 formed by bending a strip of porcelain, enamelled metal, or
glazed earthenware in the shape of a channel or groove, whilst in a plastic or soft
condition, and attaching same to the inside of the vessel 1. This strip of porcelain
or conduit 2 extends from within about one inch from the bottom of the vessel or
retort, to the top, and near the top of the vessel a bib or spout 3 is formed as an
outlet for the acid or liquid to pass into the next vessel (see Fig. 3); this bib or
spout 3, which engages with or forms part of the conduit or passage 2, is placed
about one or two inches below the top of the rim of the vessel 1, and the outer
end of the bib or spout 3 is curved downwards.
When a series of these vessels or receivers 1-1 are employed for concentrating
acid or liquid by any of the ordinary well known cascade processes, the outer
curved end of the bib or spout 3 is placed over the rim of the next succeeding
vessel (see Fig. 3) and so on through the series, so that as the acid or liquid passes
into the first vessel of the series, it must rise from the bottom of the conduit or
passage 2, and thence up to the bib or spout 3, and pass to the top of the next
succeeding vessel 1, and so on to the end of the series; and by this means a perfect
circulation of the acid or liquid is ensured, the lighter or weaker acid always being
at the top.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
The vessel having a conduit or passage 2, the bottom of which is open, and
near to the bottom of the vessel, the top of such conduit terminating in a curved
spout or overflow below the top of the vessel 1, as and for the purpose herein
described, and substantially as illustrated by the annexed drawings.
