Street, Cape Town, Gentlemen.
I, JAMES VINCENT PATERSON, of Coin Street, Stamford Street, in the County of
London, Secretary to a Public Company, do hereby declare the nature of this
invention to be as follows:-
This invention relates to an improved tank adapted for conveying sulphuric acid
or other corrosive liquid in bulk.
The tank is constructed with an outer shell of steel or iron, and with an inner
lining of an alloy of lead and antimony or copper, all the joints of which lining are
chemically burned, the space between the shell and lining being packed with any
suitable substance which is insoluble in the intended liquid-contents of the tank.
When intended for the sea-carriage of such liquids the tank is shaped
conformably to the vessel in which it is to be placed, and is constructed of a
cellular formation with longitudinal and transverse divisions which serve to prevent
the movement of the liquid from endangering the stability of the vessel.
When adapted for the land-carriage of such liquids, the tank is shaped
conformably to the requirements of the railway or road transit, but need not be of a
a cellular formation.
Ventilation is or may be provided for by any suitable arrangement of funnels or
the like.
The top of the tank is flanged and adapted to carry a removable cover, which is
of a like double and packed construction to that of the body of the tank.
In the bottom of the tank is formed a well, towards which the surrounding
parts of the tank-bottom incline so as to cause the liquid-contents of the tank to
gravitate or drain thereinto, and from which such liquid may be conveniently
pumped.
Dated this 9th day of February 1897.

Street, Cape Town, Cape Colony, South Africa, Gentlemen.
1, JAMES VINCENT PATERSON, of Coin Street, Stamford Street, in the County of
London, Secretary to a Public Company, 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 an improved tank adapted for conveying sulphuric acid 5
or other corrosive liquid in bulk..
The tank is constructed with an outer shell of steel or iron, and with an inner
lining spaced apart from the shell and composed of a non-corrodible alloy of lead
with from about to about 5% of antimony or copper. All the joints of the lining
are chemically burned, and the space between the shell and the lining is packed with 1
any, suitable substance which is insoluble in the intended liquid-contents of the
tank.
When intended for the sea-carriage of such liquids, the tank is shaped
conformably to the vessel in which it is to be placed, and is constructed of .a
cellular formation with longitudinal and transverse divisions adapted to, prevent 1
any such movement of the liquid as would endanger the stability of the vessel.
When adapted for the land-carriage of such liquids, the tank is shaped
com formably to the requirements of railway or road transit, but need not be of a
cellular formation.
Ventilation is or may be provided for by any suitable arrangement of funnels or 2
the like.
The top of the tank is flanged and adapted to carry a removable cover, which is
of a like double and packed construction to that of the body of the tank.
In the bottom of the tank is formed a well, towards which the surrounding parts of
the tank-bottom incline so as to cause the liquid-contents of the tank to gravitate 2
or drain thereinto, and from which such liquid may be conveniently pumped.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
A tank for conveying corrosive liquid in bulk constructed and adapted as herein- 3
before described.
