Improvements in Compositions for Coating the Bottoms of Navigable
Vessels and the Submerged Portions of Floating and other
Structures.
I HENRY ALLINGTON HARVEY of No. 19 Latona Road, Peckham, in the county
of Surrey, Paint Manufacturer do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to provide coating compositions of superior
quality which can be easily applied and when applied tenaciously adhere to the
surface and prevent the adhesion of marine growth. For that purpose I combine
with a basis of finely reduced arsenical mundic carbon, or charcoal, arsenic and
sulphate or other salts of copper without, or with tallow.-These substances in
varying proportions as required are ground or mixed with oil and dryers, or other
suitable fluid.
To give cohesion I add oxide of zinc or other pigment, colouring matter may be
added as desired.
The following have been found to answer :-
46 parts by weight Arsenical mundic.
White Arsenic.

I HENRY ALLINGTON HARVEY of No. 19 Latona Road Peckham London in the
county of Surrey Paint Manufacturer, 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 :-
The object of my present invention is to provide for ships and navigable vessels
coating compositions of superior quality which can be easily applied and when applied
tenaciously adhere to the surface and prevent the adhesion of marine growth. For
that purpose I combine with a basis of finely reduced arsenical mundic, carbon, or
charcoal, arsenic, and sulphate or other salt of copper without or with tallow. These
substances in varying proportions as required are ground or mixed with oil and dryers
or other suitable fluid.
To give cohesion I add oxide of zinc or other pigment. Colouring matter may be
added as daairad

colouring matter.
The above ingredients are all ground in a suitable vehicle such as boiled linseed oil
or varnish to a consistency fitted for application by a brush.
It will be evident that the proportions of the various substances may be considerably
varied and that the pigment tallow and colouring matters may be omitted or one or
more of them used as desired and that any suitable pigments and colouring matter
may be used.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is.
First. The combination of arsenical mundic carbon or charcoal white arsenic
sulphate or other salt of copper substantially in the manner and for the purpose
set forth.
Second. The combination of arsenical mundic charcoal or carbon, white arsenic,
sulphate or other salt of copper, with a pigment, tallow, and colouring matter, or any
of them substantially in the manner and for the purpose set forth.
