PROVISIONAL SPECIFICATION left by the said William Robert Lake.
at the Office of the Commissioners of Patents, with his Petition, on
the 26th October 1871.
I, WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co.,
3 Patent Agents, Southampton Buildings, London, do hereby declare the
nature of the said Invention for "AN IMPROVED METHOD OF PRESERVING
WOOD," a communication, to be as follows:-
:—
:
My method consists in a simple process of saturating the wood in
resin oil, warm or cold, or at any required temperature according to
circumstances. In the event of the wood being of moderate dimensions,

page_text: in thin boards for instance, I apply the oil cold, and for wood of large
dimensions I apply the oil hot. In either of the above cases the appli-
cation is made by immersing the wood in the oil, or with a brush, or
in any convenient manner whatever, so that the wood is thoroughly
saturated with the oil.
in thin boards for instance, I apply the oil cold, and for wood of large
dimensions I apply the oil hot. In either of the above cases the appli-
cation is made by immersing the wood in the oil, or with a brush, or
in any convenient manner whatever, so that the wood is thoroughly
saturated with the oil.
From the foregoing description it will be seen that I apply the resin
oil directly to the wood, instead of applying a paint or other like com-
position composed of resin oil and other ingredients.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Robert Lake in the Great Seal Patent 1
Office on the 24th April 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,

that I, the said William Robert Lake, my executors, administrators, -

Patent.
NOW KNOW YE, that I, the said William Robert Lake, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement :-
My method of preserving wood consists in a simple process of
saturating the wood in resin oil, warm or cold, or at any required
temperature according to circumstances. In the event of the wood
being of moderate dimensions, in thin boards for instance, I apply the
oil cold, and for wood of large dimensions I apply the oil hot. In either
of the above cases the application is made by immersing the wood in the
oil, or with a brush, or in any convenient manner whatever, so that the
wood is thoroughly saturated with the oil.
From the foregoing description it will be seen that I apply the resin
oil directly to the wood, instead of applying a paint or other like com-
position composed of resin oil and other ingredients.
Having thus described the said Invention, as communicated to me by
my foreign correspondent, and the manner of performing the same, I
wish it understood that I claim, the application of resin oil, hot or cold,
for the preservation of wood from decay and from destruction by worms
or insects, substantially as described.
In witness whereof, I, the said William Robert Lake, have here-
unto set my hand and scal, this Twenty-fourth day of April,
in the year of our Lord One thousand cight hundred and
seventy-two.
Witness,
