IMPROVED PAINT OR COMPOSITION FOR COATING AND PRESERVING WOOD, IRON, OR
OTHER METALS

My Invention has for its object to prevent the fouling of ships' bottoms whether
of iron, or wood sheathed with copper, and generally the preservation of wood, iron,
or other metals whether submerged in water, buried in the earth or exposed to the
action of the atmosphere or other deteriorating cause.
My Invention consists in coating ships' bottoms or other surfaces of any of the
materials named with a paint or composition consisting principally of tannic acid
mixed with glycerine or other substance capable of wholly or partially dissolving
it, the whole being mixed with ordinary paint or any other combination or mixture
of materials capable of being used as paint.

EDMUND PERCY WELLS of Notting Hill in the county of Middlesex
"AN
IMPROVED PAINT OR COMPOSITION FOR COATING AND PRESERVING WOOD, IRON OR
OTHER METALS
"
:
My invention has for its object to prevent the fouling of ships' bottoms whether
of iron or wood or wood sheathed with copper or other metal and generally the
preservation of wood, iron or other metals whether submerged in water, buried in
the earth, or exposed to the action of the atmosphere or other deteriorating
influences.
My invention consists of a composition for coating ships' bottoms, or other
surfaces of any of the materials named, such composition consisting of tannic acid
(or a substance containing tannic acid) mixed with paint or other combination or
mixture of materials capable of being used as paint.
In preparing my improved paint or composition I have found the following
proportions to answer well:-I take about six pounds of tannic acid and intimately
mix the same with about half a gallon of linseed oil, which is then well mixed with
about one hundred weight of paint or other suitable composition, and the material
is then ready to be applied to the surfaces to be protected or preserved.
I have given the above proportions as those which I have found to give good
results but it will be understood that they may be somewhat varied.
For preserving wood and other substances which do not require painting I may
dissolve the tannic acid in glycerine or intimately mix it with varnish or oil
and apply either composition in a similar manner as ordinary paint or varnish is
applied.
Having thus described my said invention and the best means I am acquainted
with for carrying the same into effect What I claim is :-
Firstly. The manufacture and use of the herein before described paint or com-
position consisting of tannic acid (or a substance containing tannic acid) mixed
with paint or other substances capable of being used as paint, in substantially the
proportions above named.
-
Secondly. The use of tannic acid in compositions for painting or coating wood
or iron and other metals as herein before described.
In Witness whereof I the said Edmund Percy Wells have hereto set my
hand and seal this fifth day of February in the year of our Lord one
thousand eight hundred and eighty three
