A communication from MAMIAN HAMILTON, of 111, West 22nd Street,
New York, United States of America.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E., do hereby declare the nature of this invention to be as follows:-
:-
The object of this invention is to produce a material adapted for building purposes
which shall possess the desirable qualities of wood and be capable of application to
all or most of the uses to which wood is applied and at the same time shall be
substantially fire-proof.
In carrying this invention into practice any ordinary paper such for example as that
made from straw, manilla, or other like material is made in rolls in the usual way
except that when in pulp there is added a solution composed of silicate of soda one
part, alum two parts, bi-carbonate of soda two parts, aqua ammonia three parts,
and bi-carbonate of potassium one part, which are dissolved in water and added
to the pulp in the proportions of about eight parts of the former to forty parts of
the latter. During the process of manufacture, a sizing of starch is added to the
paper in the usual manner. If desired the pulp may be coloured to cause it to
resemble any kind of fancy wood.
The sheets of paper thus made may afterwards be coated with a cement
composed of glue two parts to one of water and then combined preferably under
heat and pressure into a compact board, the dimensions and thickness of which
may be varied at will.
After the material has been thus formed it should be kept under pressure for a
period of generally from one week upwards-depending upon circumstances―in
order that the boards may become thoroughly cured or seasoned, after which they
are capable of being worked in the same manner as any of the hard woods of
commerce and of being applied to the same purposes.
While the before mentioned proportions and materials are preferably used they
be varied both with relation to each other and to the pulp without departure
from the spirit of the invention.

I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E., 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 :-

While the before mentioned proportions and materials are preferably used they
may be varied both with relation to each other and to the pulp without departure.
from the spirit of the invention.
Having now particularly described and ascertained the nature of the said
invention, as communicated to me by my foreign correspondent, and in what
manner the same is to be performed, I declare that what I claim is :-
1. An artificial wood composed of paper pulp, silicate of soda, alum, ammonia,
bi-carbonate of soda and bi-carbonate of potassium in substantially the proportions
specified made into sheets and the same combined by means of a cement substantially
as and for the purpose described.
2. An artificial wood composed of paper pulp, silicate of soda, alum, ammonia,
bi-carbonate of soda, and bi-carbonate of potassium in substantially the proportions
specified, made into sheets and the same cemented together under pressure substan-
tially as and for the purpose described.
