WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVED DRYING AND OTHER COMPOSITIONS
OR COMPOUNDS, CHIEFLY DESIGNED FOR MIXING WITH OILS, PAINTS, AND SIMILAR
SUBSTANCES." A communication from abroad by Alfred Winsor Pratt, of Flushing,
New York, and Henry S. Lambert, of East Orange, New Jersey, both in the United
States of America; Manufacturers.
This Invention relates chiefly to improved compositions or compounds adapted to
be used in connection with oils and paints for the purpose of expediting the drying
of the same, as well as for the purpose of improving their body.
The said Invention is carried into practice as follows, that is to say :-'
-To prepare
forty-five gallons of the said drying composition or "dryer" I take about ten lbs. of
caustic soda; seven and a half gallons of oil (linseed preferred); thirty-four lbs. of
resin; and ten gallons of the aqueous solution of the chloride of manganese, such as
is obtained as a residuum in the ordinary method of manufacturing chlorine gas
from black oxide of manganese. I dissolve the soda in water so as to produce a
Price Ad I

page_text: strong lye which mixes with the oil, and I boil the mixture together in a kettle or other
receptacle until the mass becomes plastic; then I put in as much of the aforesaid
solution of chloride of manganese as the plastic mass will take up; after this I
cleanse the mixture with water; then I add the resin, and simmer the whole mass
in a suitable receptacle over a fire until it becomes homogeneous, then I remove the
mixture and add thereto about thirty-five gallons of linseed oil.
Other oils may be used instead of linseed oil; other resinous substances instead
of resin; and various other changes may be made without departing from the spirit
of my said Invention.
In the course of the above process various incidental compositions are necessarily
produced, some of which I claim as new and useful. For example, the very first
step produces a soapy composition, consisting of caustic soda and a vegetable oil;
this is suitable for various uses. At a further stage I also produce a composition
consisting of caustic soda, a vegetable oil, and aqueous solution of chloride of
manganese.
For cheapness and to produce a weaker product, spirits of turpentine or some
similar fluid may be employed to cut and reduce the consistency of the whole to a
thin fluid, suitable for application in connection with paints, oils, and the like in
the usual manner.
My improved compound or "dryer" may be subjected to many changes without
departing from the said Invention; for example, only seven and a half gallons of
oil may be employed instead of thirty-five, turpentine or naphtha being employed to
take the place of the remainder of the oil, reducing the mixture to the proper con-
sistency for use.
I also sometimes employ as an ingredient in said mixture with the principal
ingredients above enumerated fourteen lbs. of nitrate of lead, or fourteen lbs. of
brown sugar of lead. The proportions of the salts of lead and some other ingredients
may be varied. The two last-named ingredients are dissolved in water and applied
in solution with the aqueous solution of chloride of manganese.
In lieu of the nitrate of lead or the brown sugar of lead above mentioned I some-
times employ white sugar of lead, or other salts of lead, sulphate or borate of
manganese, sulphate of zinc, or any one of similar suitable mineral ingredients.
Two or more of these salts may be used together. The effect of the addition of the
salt of lead, or its equivalent, is to improve the said "dryer."
In preparing the aqueous solution of the chloride the first step is to mix black
oxide of manganese with hydrochloric acid, muriatic acid, sulphuric acid, or some
other suitable acid, and subject the same to the operation of heat which will drive
off the chlorine gas. The residuum will then be an aqueous solution of chloride of
manganese, to which water is added, making the solution which constitutes one of
my principal ingredients. Other metallic oxides suitable to this purpose may
however be substituted for black oxide of manganese, the result being a metallic
chloride, or its equivalent, which will answer the same purpose.
I sometimes substitute for the chloride of manganese, copper, or some compound
of copper reduced to a liquid state by the actionof acids or other suitable substances.
The composition thus made is used as a paint.
Having thus fully described the said Invention, as communicated to me by my
foreign correspondents, and the manner of performing the same, I wish it under-
stood that I claim,-
First. A drying composition compounded of caustic soda, oil; resin, and' an aqueous
solution of chloride of manganese, or-their equivalents, substantially as set forth.
Second. A drying composition compounded of caustic soda, oil, resin; an
aqueous solution of chloride of manganese, and a salt or salts of lead. or the
equivalents thereof.
→
Third. A composition compounded of caustic soda, oil, a resinous substance, and
copper, or some compound of copper, reduced to liquid form by the action of acids
or other suitable agents.

page_text: Fourth. A composition of matter consisting of caustic soda, oil, and aqueous
solution of chloride of manganese.
.
Fifth. A composition of matter consisting of caustic soda and a vegetable oil.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Fourth day of December, in the year of our Lord
One thousand eight hundred and seventy-eight.
