We, LEWIS ANDERSON SMART, of Westonlea, Dumbarton, in the County of
Dumbarton, North Britain, Engineer, and HENRY ROBERTSON, of 8, Allan Place,
Dumbarton, aforesaid, Mason, do hereby declare the nature of this Invention to be
as follows, that is to say :-
Our said Invention has for its object to prepare improved cement compositions
which are advantageously applicable for steel and iron ships, for coating metal plates
and other parts for filling spaces and for analogous purposes. As compared with
compositions hitherto used for such purposes, our improved compositions, whilst of
less weight, possess greater strength, and have as great if not greater adhesiveness.
In making our improved compositions we use Portland or similar cement, but
instead of combining with it sand we use what is known as coke breeze, or we use
engine ashes, or smithy ashes, or any suitable material of like nature. We may
use any one of such materials or a mixture of any two or more of them; and in
some cases we may use a portion of sand along with one or more of such materials.
The proportions of the cement and of the ashes or mixture may vary in different
cases according to the particular requirements of each application. It may however
be stated by way of example that good and satisfactory results are obtainable by
combining one part by measure of cement with one part of the ashes or mixture.
The improved compositions are to be prepared and applied in the same manner as is
done with compositions made with cement and sand.

Dumbarton, aforesaid, Mason, 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, that is to say:-

We may state generally that the ashes or mixture may be combined with the cement
in any of the proportions in which sand has hitherto been combined therewith. The
improved compositions are to be prepared and applied in the same manner as is done
with compositions made with cement and sand.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed, we declare that what we
claim is :-
The making of improved cement compositions by combining coke breeze,
engine ashes, or smithy ashes, or the like with Portland cement substantially as
hereinbefore described.
