AN IMPROVED COMPOSITION OR PAINT FOR COATING BRICK- WORK, IRON WORK AND THE BOTTOMS OF SHIPS, AND FOR SIMILAR PURPOSES
Year: 1885

page_text: I HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co, Patent Agents,
Southampton Buildings, in the County of Middlesex do hereby declare the nature
of my invention for "AN IMPROVED COMPOSITION OR PAINT FOR COATING BRICK-
WORK, IRON WORK AND THE BOTTOMS OF SHIPS, AND FOR SIMILAR PURPOSES" 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 a composition in the form of paint, useful for application
to the bottoms of marine and other vessels whether made of wood or iron; to
smoke stacks and iron work exposed to air and water and liable to rust; and to
outside brick gables, and the rear of houses; and it possesses numerous advantages
over the common kinds of paint now employed for such purposes. It is a black
liquid composition which is always ready for use and is applied with a brush under
which it flows freely.
The said composition consists of the following ingredients, combined in the
proportions stated below viz :-
Creosote or dead oil
Coal tar
Spirits of turpentine
Plumbago
-
8 gallons.
6 gallons
1 gallon.
8 ounces by weight.
These ingredients are to be thoroughly mingled by stirring or otherwise.
For protecting the bottoms of wooden ships or vessels this composition is found
to be much superior to the ordinary copper paint which is now extensively applied
to them, for instead of covering the outside of the wood like a plaster, as copper
and many other paints do, it penetrates and fills its pores, and being itself
absolutely waterproof thereby renders the wood better adapted, than when other
paints are used, to withstand the action of the water. When this composition is
applied to the bare wood, sea worms will not enter the wood and barnacles will
not grow upon it.

page_text: When used upon iron vessels, either inside or outside, or upon smoke stacks or
iron work of any description which it is desired to protect from exposure to the air
or water, this composition is superior to other common compounds or paint adapted
to such uses.
It will not flake or scale off and the iron will not rust under it. It
is antifouling on the bottoms of iron as well as of wood vessels, and prevents
barnacles or grass from growing thereon. Whether it be applied to wood or iron
ships or vessels, two or three coats are to be used.
For outside brick, gables, and the rears of houses, it serves to prevent rain from
entering the bricks and it keeps the walls entirely free from dampness.
It is much cheaper than other compositions of its class, which is due to two
causes; the quantity in each case being the same, first it costs less to make it than
to make any of the other kinds, and secondly it covers a greater surface than other
compositions cover.
When this paint compound is intended for covering iron work it is advisable to
prevent any possible damage that might arise from the presence of acids contained
in the paint by the addition of sufficient lime to neutralize such acid, and for this
purpose a small quantity of lime is necessary, the quantity varying to some extent
with the amount of acid contained in the several ingredients comprising the
compound.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed as communicated to
me by my foreign Correspondent I declare that what I claim is
First. The above described composition or paint consisting of creosote or dead
oil, coal tar, spirits of turpentine, and plumbago, in the proportions substantially as
Bet forth.
Second. The above described composition or paint consisting of creosote or dead
oil, coal tar, spirits of turpentine, and plumbago, in the proportions substantially as
set forth, and an alkali to neutralize such acid as the said composition may contain.
Dated this 19th day of June 1885.
