PROVISIONAL SPECIFICATION.
A New or Improved Paint.
We, WILLIAM WARD of 22 Milton Street, South Shields, in the County of
Durham, Patent Paint Manufacturer, and JOHN OGLE WALLACE, of Etal Villa,
North Shields in the County of Northumberland, Merchant, do hereby declare the
nature of this invention to be as follows:-
This invention relates to an improved liquid enamel paint containing caoutchouc
and specially prepared for coating the inside of petroleum oil tanks on ship board and
otherwise; or for use in ships intended for the carrying of petroleum oil cargoes in
bulk, or tanks specially constructed for storing the oil on land.
Hitherto all paints used for the preserving of petroleum oil tanks on ship board
and otherwise have failed to retain their tenacity owing to the penetrable properties
of petroleum oil which, in a remarkably short space of time, causes the paint to
become soft, the coloring matter to become extracted and in many instances causes
the oil to be more or less discolored as the paint is quickly removed by the action
of the oil, thus leaving the surface of the iron or steel exposed to the ravages of the
petroleum oil which very rapidly causes corrosion, in the shape of fine rust, all over
the face of the steel or iron plates, when leakage through the seams, butts, rivets
and joints of the plates are sure to follow, thereby causing great danger to steam-
ships on account of the inflammable nature of the cargo.
Cements have been freely used to counteract the leakage of these oil tanks but
inasmuch as the cements are more or less porous they gradually become saturated
with the oil and useless as a preventive of leakage even where the cement is applied
to the extent of six inches in thickness and in many cases the cement loses its hold
and comes off, failing to adhere to an oily surface.
To remedy these and other concomitant evils is the object of the invention, to
attain which we manufacture the caoutchouc liquid enamel paint, with which we
coat the surface of the material to be protected, of the following ingredients in the
manner following, that is to say, for the first coating the paint consists of the
following incredients

page_text: These ingredients are treated in the following manner:-
Nos. 1, 2 and 3 ingredients are placed in an iron vessel furnished with a lid and a
revolvable stirrer and gradually heated by steam until Nos. 2 and 3 become
dissolved then Nos 5, and 7 are added and the same allowed to remain till all are
dissolved. The lid or covering of the said vessel must be kept closed till the
contents become blended into a thick creamy consistence, the revolving agitator
connected with the vessel must be kept slowly in motion until all are thoroughly
dissolved when we allow the same to cool down into a paste by shutting off the
steam, after which we add Nos. 4, 8, 9 and 10 ingredients then gradually heat up
the whole contents keeping the agitators in motion till all the ingredients are
thoroughly incorporated then we let it cool and add further wood naptha if and
when required until it is of a proper consistence so as to be applicable with an
ordinary paint brush. It is then ready for use and forms a very hard enamel
surface.
Where two coats are required the second coating is manufactured precisely the
same way as the first the only difference is in the No. 10 ingredient where we make
a slight difference in the coloring matter in order to ascertain more readily whether
the surface treated has been once or twice coated, thus preventing frauds, omissions
or mistakes.
The important features in this invention are that it will preserve iron, steel,
metal, cement or wood from the influences of petroleum oil, thus preventing all
leakage and by so doing saving the oil that would otherwise be lost or wasted
beside minimising the danger of fire.
The careful combination of the ingredients enables it to be applied over
surfaces previously coated with other paints whether of vegetable or mineral
preparations.
We do not confine ourselves precisely to the quantities of the ingredients herein
set forth but may vary same so far as the resulting product remains substantially
the same.

A New or Improved Paint.
We, WILLIAM WARD, of 22 Milton Street, South Shields, in the County of
Durham, Patent Paint Manufacturer, and JOHN OGLE WALLACE, of Etal
Villa, North Shields, in the County of Northumberland, Merchant, 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 liquid enamel paint containing caoutchouc,
and specially prepared for coating the inside of petroleum oil tanks on ship-board
and otherwise; or for use in ships intended for the carrying of petroleum oil
cargoes in bulk, or tanks specially constructed for storing the oil on land.

a revolvable stirrer and gradually heated by steam until Nos. 2 and 3 become
dissolved then Nos. 5, 6 and 7 are added and the same allowed to remain till all

Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
:-
The combination of materials herein described in the proportions given or in
substantially equivalent proportions constituting a paint for the purpose set
forth.
