page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Joseph Bramah, do hereby describe and ascertain the nature of my said
Invention, and in what manner the same is to be prepared and applied by the
following description thereof, that is to say:-
That the mineral or earth called Parker's cement or Roman cement if
applied to timber of all descriptions, as to the timbers of buildings, ships, and
all other places where timber is used infected with the rot commonly called
the dry rot, will compleatly put a stop to the enfection to which it shall be so
applied, and will prevent its recurrence. The mode of application for this
purpose is the following:-Mix the Parker's cement or Roman cement in a
pure and fresh state with water, so as to form a composition of the consistency
of white-wash or lime-wash; scrape the timbers infected as perfectly clean as
possible, and then coat it with the mixture of the Parker's or Roman cement.
When first used will prevent such timbers from being liable or subject to the
said rot called the dry rot; secondly, the said Parker's cement or Roman
cement used in combination with linseed oil or any other oil used in the
mixture of paint, forms an excellent paint or pigment, and is applicable
particularly for covering work exposed to the air. It may be also, very
beneficially applied in painting coach pannels, floor-clothes, and all other things
where paint is commonly used. For all these purposes it is necessary, that the
said Parker's or Roman cement should be ground and sifted, very fine, and
should always be used: in a. fresh and pure state...
