I, ALEXANDER ANGUS CROLL of the Wool Exchange Coleman Street in the City
of London Civil Engineer do hereby declare the nature of my invention for
IMPROVEMENTS IN THE CONSTRUCTION OR MANUFACTURE OF RESERVOIRS OR
APPARATUS FOR THE STORAGE OF PETROLEUM AND OTHER INFLAMMABLE LIQUIDS
to be as follows:-
The object of my invention is to protect the material of which the Reservoirs or
apparatus in which the storage of petroleum turpentine or other imflammable
liquids, is effected from the action of the liquid which comes in contact with it and
also to protect the stored liquid from being discolored or injured by contact with
the reservoirs or, storage apparatus and to improve the economy and efficiency of
the storage.
For this purpose I construct my improved reservoirs or storage apparatus of
metal or other material such as lead, iron, slate, concrete or asphalte and these
materials I coat with shellac and upon the shellac I apply a zinc paint such as
white oxide of zinc paint and by these means I am enabled to prevent destructive
or deleterious action being set up between the materials of the reservoir or storage
apparatus and the zinc paint coating or the contained liquids with greater durability
and economy.
The shellac I apply in the form of a solution of say about 2 to 4 lbs. of shellac
dissolved in one gallon of methylated spirit and find it most convenient to proceed
somewhat thus.
This dissolved shellac is spread over the inner surface of the materials forming
the reservoirs. When this coating is dry; a result which generally takes about
twelve hours to effect after application I spread over the surface one or more
coatings of what is generally known as white zinc paint.

I ALEXANDER ANGUS CROLL of the Wool Exchange Coleman Street in the City

and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:―
The object of my invention is to protect the material of which the Reservoirs or
apparatus in which the storage of petroleum, turpentine or other imflammable
liquids, is effected from the action of the liquid which comes in contact with it
and also to protect the stored liquid from being discolored or injured by contact
with the reservoirs or storage apparatus and to improve the economy and efficiency
of the storage.
For this purpose I construct my improved reservoirs or storage apparatus of
metal or other material 'such as lead, iron, slate, concrete or asphalte and these
materials I coat with shellac and upon the shellac I generally apply a zinc paint
such as white oxide of zinc paint but this latter application is dependent on the
material of the tank or the liquid stored and by these means I am enabled to
prevent the destructive or deleterious action being set up between the materials
of the reservoir or storage apparatus and the zinc paint coating or the contained
liquids with greater durability and economy.
The shellac I apply in the form of a solution of say about 2 to 4 lbs. of shellac
dissolved in one gallon of methylated spirit and find it most convenient to proceed
somewhat thus.
This dissolved shellac is spread over the inner surface of the materials forming
the reservoirs. When this coating is dry; a result which generally takes about
twelve hours to effect after application I spread over the surface one or more
coatings of what is generally known as white zinc paint when such addition is
desired particularly in the case of petroleum and such like liquids.
.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
"
The employment of shellac as a coating or lining for tanks, reservoirs or
apparatus for the storage of Petroleum, and other inflammable liquids either with
or without the addition thereupon of a coating or additional covering of white or
