COMPLETE SPECIFICATION.
Improvements in Composition for Coating or Painting Roofs,
Vessels, and the like.
I, DAVID FLETCHER LUCAS, residing at 552, Pacific Street, Brooklyn, in the County
of Kings, State of New York, United States of America, Physician, 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 :-
My new and useful composition is designed to produce a paint which will resist
heat to the highest obtainable extent, which will be flexible and not solidify or crack,
which will not blister under the heat of the sun, and which will be almost un-
susceptible to cold temperatures and for the purpose of attaining these results in the
simplest and most direct manner without the use of substances found objectionable
or deleterious in paints of this character without high cost of production.
My invention consists of the following ingredients combined as hereinafter
snacified

I, DAVID FLETCHER LUCAS, residing at 552, Pacific Street, Brooklyn, in the County
of Kings, State of New York, United States of America, Physician, do hereby declare
the nature of this invention and in what manner the same is to be performed, to be

My new and useful composition is designed to produce a paint which will resist
heat to the highest obtainable extent, which will be flexible and not solidify or crack,
which will not blister under the heat of the sun, and which will be almost un-
susceptible to cold temperatures and for the purpose of attaining these results in the
simplest and most direct manner without the use of substances found objectionable
or deleterious in paints of this character without high cost of production.
My invention consists of the following ingredients combined as hereinafter
specified
Coal tar
Rosin oil
Kerosene or benzine
Ochre (preferably gray ochre)
Chloride of sodium
Carbonate of soda (sal soda)
Sulphate of iron. (copperas)
Litharge
Water
80 gals.

In the first step of the production of the paint, I add eighty gallons of coal tar
eight pounds of ochre (preferably gray ochre) and eight pounds of chloride of sodium,
and after mixing thoroughly, I then add four gallons of rosin oil and four gallons of
kerosene or benzine, again mixing the composition thoroughly.
I then dissolve eight pounds of sulphate of iron in five gallons of boiling water
and dissolve eight pounds of the carbonate of soda in a similar quantity of boiling
water which makes a total of ten gallons employed, and these solutions of the
sulphate of iron and the carbonate of soda are then thoroughly mixed. The first
combined ingredients and these last combined ingredients of the sulphate of iron
and carbonate of soda, together with four pounds of litharge, are then mixed and let
stand for about ten days, when the composition is ready for use. Instead of adding
the litharge last, it may be added to the first combined ingredients before the
sulphate of iron and carbonate of soda are added, or the said litharge may first be
added to the coal tar.
I find in actual practice, that the chloride of sodium, the carbonate of soda and the
sulphate of iron chemically combine with the other ingredients and that the result
is a composition incapable of being produced otherwise than by this invention. It
is of greatest importance that the various ingredients of which my composition
consists be combined in the proper proportions and manner, as it has been ascertained
by actual experiment that a different and inferior result is obtained by other pro-
portions and combinations.

page_text: This composition produces a coating or paint which is unsurpassed for the purpose
of coating roofs and other structures, and for coating boilers, boiler coverings, etc.,
and the coating of paint when thus applied is very durable and will not solidify or
crack, and will not melt or run under ordinary temperatures, and will not blister
under the heat of the sun, nor will it freeze in the temperature of winter.
When my improved composition is used for coating or painting the bottom of
ships, I employ in connection therewith poisonous substances which are designed to
prevent the bottom of the ship from being attacked by ship worms and other pests
of this class. These substances are as follows:
prevent the bottom of the ship from being attacked by smp worms and other pests
of this class. These substances are as follows:
Paris green
Arsenious acid
4 lbs.
2 lbs.
In combining these ingredients with those hereinbefore specified, the Paris green
is added to the ochre and the arsenious acid is boiled with the carbonate of soda, the
process being otherwise the same as that hereinbefore set out.
I also add, in practice, to both of the herein before mentioned compositions, two
pounds of sulphuric ether, which being highly volatile, does not form a permanent
element, and is therefore not included as an element of said compositions, but said
ether when first added, gives the paint a more consistent and fluid quality than it
has after the ether has been volatilized.
The ingredients of my improved composition may be thoroughly mingled by
agitation or in any desired manner, care being taken to follow the instructions here-
in before given, and said composition as set out in the formula first given, constitutes
a fire proof and flexible paint which is particularly adapted for use in coating or
painting the roofs of buildings and similar structures, and by adding the Paris green
and the arsenious acid as described, I produce a compound which is unsurpassed for
the purpose of coating or painting the bottoms of vessels.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. The herein described composition of matter, consisting of a base composed of
coal tar, eighty gallons, rosin oil, four gallons, kerosene, four gallons, ochre, eight
pounds, and chloride of sodium eight pounds, with which is combined merged solu-
tions of carbonate of soda, eight pounds, and sulphate of iron, eight pounds in boil-
ing water, substantially as set forth.
