page_text: We WILLIAM MILLAR of 33 Sherbroke Road Modeller and Plasterer, and
CHRISTIAN FAIR NICHOLS of 2 Landridge Road, Daine, both of London in the
county of Middlesex, do hereby declare the nature of our invention for "A NEW
OR IMPROVED FIBROUS, FIREPROOF AND WATERPROOF COMPOSITION FOR CON-
STRUCTIVE DECORATIVE AND OTHER PURPOSES." and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement:-
This invention relates to certain new or improved fibrous fireproof and water-
proof material, and has for its object to provide a material for constructive
decorative or other purposes, and for covering structures which shall also be
applicable to all purposes to which fibrous plaster, carton-pierre, papier-maché,
wood or other material at present used are applicable, and also be proof against the
destructive action of fire and water.
Our fibrous material may be composed of the following ingredients in the
approximate proportions set forth. The aggregate consists of brick dust or ground
pummice stone, in combination with slag-wool, with which is incorporated about
equal bulk of Portland or other cement and to this agglomerate we add for the
purpose of setting the mass
ca .
For the purpose of imparting to the material, flexibility, strength, lightness, and
adhesiveness, and for fixing purposes the above mixture while in a plastic state is
laid on specially woven wire, or perforated zinc, or screen, specially prepared and
rendered fireproof by steeping in a solution of Borax or Ammonia, or for the saine
purpose Tow or other fibre similarly prepared may be incorporated with the
mixture.

page_text: For indurating and imparting an intense hardness to the articles constructed by
the above process, they are saturated with chloride of calcium, then immersed in a
bath of silicate of soda of about 20° specific gravity; they are next washed with
a solution of Bicromate of Potash.
This fibrous fireproof and waterproof composition is particularly applicable for
constructing external moulding or decorations, or for rendering fireproof ceilings,
walls, wooden or iron beams, girders, stairs, columns, and other articles used in
building construction. We have mentioned above the proportions which to the
best of our knowledge are most suitable for the combination of the ingredients of
our composition, but we do not bind ourselves to the exact and precise proportions
before stated, as the same may be varied or altered according to circumstances
without deviating from the principle of our invention.
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 fibrous compound hereinbefore described for constructive, decorative and
other purposes consisting of the combination of the ingredients above set forth,
which shall be fireproof and waterproof substantially as described.
Dated this fifth day of March 1885.
