PROVISIONAL SPECIFICATION.
An Improved Paint or Composition Especially suitable for Coating
Ships' Bottoms, and the Process of Manufacturing the same.
We, JAMES BAYNES Ph. D. F.I.C., F.C.S. Analytical Chemist, Royal Chambers,
Scale Lane Hull, WILLIAM HALL DOUGHTY, Commission Agent 37 Linnams Street
Hull and HENRY TOM GREAVES Colour Manufacturer of Crown Paint Works Hull,
do hereby declare the nature of this invention to be as follows:-
According to this invention we first obtain carbolate of copper and then incorporate
with it arsenic together with materials suitable for forming a paint so that our
improved paint can be applied like ordinary paint drying readily and producing a
smooth enamel like surface whilst its composition prevents barnacles from attaching
themselves or vegetation from growing upon the surface protected by it and it also
acts as a preservative for wood.
We proceed as follows:-we take copper oxide and add to it carbolic acid allowing
the reaction to continue for say 60 hours.
We then pass the resulting compound through granite rollers and afterwards heat
it to about 160° F. for 2 hours mixing in the following ingredients.
Marine varnish.
Zinc white.
Red lead.
Orange lead.
Resin.
Turpentine.
Naphtha.
Arsenic.
Oxide of iron.
The compound is then passed again through the granite rollers after which it is
allowed to stand for 3 days after which it is ready for use. For iron ships it should
be used over a coat of priming composition, to prevent actual contact between the iron
and copper.

COMPLETE SPECIFICATION.
An Improved Paint or Composition Especially suitable for Coating
Ships' Bottoms, and the Process of Manufacturing the same.
We, JAMES BAYNES Ph. D., F.I.C., F.C.S., Analytical Chemist, Royal Chambers,
Scale Lane Hull, WILLIAM HALL DOUGHTY, Commission Agent, 37 Linnams Street,
Hull, and HENRY TOM GREAVES Colour Manufacturer of Crown Paint Works,
Hull, 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 :-
According to this invention we first obtain carbolate of copper and then incorporate
with it arsenic together with materials suitable for forming a paint so that our
improved paint can be applied like ordinary paint drying readily and producing a

page_text: smooth enamel like surface whilst its composition prevents barnacles from attaching
themselves or vegetation from growing upon the surface protected by it and it also
acts as a preservative for wood.
In carrying this invention into practice, we use the following ingredients, viz.—
1st. In making this paint or composition we place the copper scales in an air-tight
vessel with the carbolic acid for several days, until it becomes a perfect carbolate,- we
then remove the mixture into a mixing pan and add the oxides of zinc and iron, the
red lead, arsenic, and boiled seed oil in the above quantities, when well mixed we run
it through granite rollers until it becomes very fine.
2nd. We next transfer it into No. 1 heating pan over a clear furnace and get it to
near boiling heat, at which point we keep it for two hours, at the same time we melt
the shellac or other gums in No. 2 pan and when thoroughly dissolved add the boiled
seed oil and keep it at a gentle heat for thirty minutes then add three parts of
turpentine the liquid must be added to No. 1.
3rd. In number three pan we dissolve the resin, after which is added the sugar of
lead and keep it gently boiling for 30 minutes, then add seventeen parts of turpentine,
by this time it will become a bright liquid and may be run into No. 1 pan, great care
must be taken in keeping it well stirred until the heat is reduced to 70 degrees
Fahrenheit when the mineral naptha must be slowly added and kept well stirred until
cool.
The composition is applied with a brush in the ordinary manner.
For iron or steel structures we first apply a paint having for its basis a metallic
oxide electro positive to iron or steel, and we then apply upon such anti-corrosive
paint, the above described paint or composition.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is:
-
1. Paints in which carbolate of copper is an ingredient.
2. Paints in which both carbolate of copper and arsenic are ingredients.
3. The process of manufacturing our improved paint substantially as described.
