PROVISIONAL SPECIFICATION.
An Improved Method of Lining Barrels or other Vessels to Resist
Acids for use in Extracting Metals by Chlorination or similar
Process from their Ores.
I, THOMAS BELL, of Normanby House, South Park, in the City of Lincoln,
Manufacturing Engineer, do hereby declare the nature of this invention to be as
follows:-
•
In order to overcome the well known difficulties in providing acid proof linings to
barrels and other vessels used in the Chlorination process of extracting metals, I bave
devised an improved method of lining the interior of such barrels or other vessels
to resist the action of such acids under pressure.
For this purpose I make the vessels of any suitable material, such as steel or iron
so as to provide the necessary strength and then place in the interior thereof a
composite lining consisting of first, a layer of lead which may or may not be in
metallic union with the steel or iron barrel. Superimposed upon this, I place a
layer of gutta percha or other similar substance impervious to acids and which by
heat or a special cement is caused to unite with the lead. Upon this another layer or
covering of lead is placed also united by the same means.

COMPLETE SPECIFICATION.
An Improved Method of Lining Barrels or other Vessels to Resist
Acids for use in Extracting Metals by Chlorination or similar
Process from their Ores.
I, THOMAS BELL, of Normanby House, South Park, in the City of Lincoln,
Manufacturing 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 :-
In order to overcome the well known difficulties in providing acid proof linings
to barrels, and other vessels used in the Chlorination process of extracting metals, I
have devised an improved method of lining the interior of such barrels or other
vessels, to resist the action of such acids under pressure.
For this purpose, I make the vessels of any suitable material, such as steel, or iron,
so as to provide the necessary strength, and then place in the interior thereof a
composite lining, consisting of first, a layer of lead, which may or may not be in
metallic union with the steel or iron barrel. Superimposed upon this I place a layer
of gutta percha, or other similar substance, impervious to acids, and which by heat,
is caused to unite with the lead. Upon this another layer or covering of lead is
placed, also united by the same means.
As a modification the gutta percha may by heat be cemented direct to the barrel,
or vessel and then a coating or covering of lead can be applied on or to the gutta
percha to constitute the lining.
Having now particularly described and ascertained the nature of this invention and
and in what manner the same is to be performed I declare that what I claim is :-
1. Lining barrels or other vessels with lead and gutta percha, as above described,
to resist acids for use in extracting metals by Chlorination, or similar process, from
their ores.

page_text: 2. The employment of the composite lining also the modification, as above described,
for barrels or other vossels used in the chlorination or similar process of extracting
gold and other metals and for similar purposes for which such acid proof linings are
required, as set forth.
