WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent
Agents, Southampton Buildings, London. "AN IMPROVED PREPARATION OF OIL
TO BE APPLIED TO METAL SURFACES FOR PREVENTING OXIDATION OF THE SAME."
[A communication from abroad by Joseph Célestin Bourdenet and Adolphe
Pradou, both of Paris, France.]
This Invention relates to an improved preparation of oil for coating metals to
prevent their oxidation.
The materials I employ and their treatment are as follows, that is to say :-I
provide a vessel of stone ware, or earthenware, wood, or other material, avoiding
metal if possible. I put into this vessel as much olive-oil as will occupy three
fourths of its capacity. To this oil I add a quantity of lead, which may be
granulated, or in the form of filings, or in any other form, the quantity of lead
being equal in weight to the quantity of oil, and I allow this mixture to stand for
a few days. Experience has demonstrated that a period of nine days is the most
convenient time.
This mass becomes thickened or troubled as the lead is attacked or partly
dissolved by the olive oil; the thickened or troubled mixture which is formed
during the nine days will precipitate in twenty four (24) hours after it has been
drawn off or decanted, and the oil will become very clear and be freed from its
oxidizing qualities or principles.
Metal of all kinds may be coated or covered with the product so obtained
either in a bath, or by means of a brush, or otherwise, and when dry the said
preparation or product will form upon the surface of the metal a fatty preserving
layer or coating, which will protect the metal against oxidation. Articles so
coated may be exposed to rain or moisture without injury.
The metal may for its better protection be coated with several layers of this
preparation by submitting it to several baths.
The proportions of lead, above stated by way of example only, as well as the
time (9 days) during which the olive oil has to remain in contact with the lead,
may be varied in practice.

WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent
Agents, Southampton Buildings, London. "AN IMPROVED PREPARATION OF OIL
TO BE APPLIED TO METAL SURFACES FOR PREVENTING OXIDATION OF THE SAME."
A communication from abroad by Joseph Célestin Bourdenet and Adolphe
Pradou, both of Paris, France.
This Invention relates to an improved preparation of oil for coating metals to
prevent their oxidation.
The materials I employ and their treatment are as follows, that is to say:-I
provide a vessel of stoneware, or earthenware, wood, or other material, avoiding
metal if possible. I put into this vessel as much olive oil as will occupy three
fourths of the same. To this oil I add a quantity of lead, which is preferably
granulated, or in the form of filings, but may be in any other form or condition,
the quantity of lead being equal or about equal in weight to the quantity of oil.
I allow this mixture to stand for a few days; experience has demonstrated that a
period of nine (9) days is the most suitable time.
The mass becomes thickened or turbid as the lead is attacked or partly dissolved
by the olive oil; the thickened or turbid mixture which is formed during the niue
days will precipitate in twenty four (24) hours after it has been drawn off or
decanted, and the oil will become very clear and be freed from its oxidizing
qualities or principles.
Metals of all kinds may be coated or covered with the product so obtained either
in a bath, or by means of a brush, or otherwise, and when dry the said preparation
or product will form upon the surface of the metal a fatty preserving layer or
coating, which will protect the metal against oxidation. Articles so coated may
be exposed to rain or moisture without injury.
The metal may for its better protection be coated with several layers of this
preparation, or it may be subjected to a succession of baths for the same purpose.
The proportion of lead, as well as the time during which the olive oil has to
remain in contact with the lead, may be somewhat varied in the practice of my
Invention.
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 understood
that I claim,―
The improved preparation of olive oil treated with lead in a granulated or other
form or condition for coating metals and preventing the oxidation of the same,
substantially as set forth.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Nineteenth day of May, in the year of our Lord One
thousand eight hundred and eighty one.
