PROVISIONAL SPECIFICATION.
An Improved Manufacture of Compounds suitable for Coverings for
Floors, Walls, Ceilings, also for Tubes, Insulating Coverings, and
other purposes.
We, GEORGE JAMES DAVIS, of Overton, Ormeley Road, Balham, in the County
of Surrey, Engineer, and EDWARD JONES, of 61 St. Mary Axe, in the City of
London, Mining Engineer, do hereby declare the nature of this invention to be as
follows:-
Our invention relates to the production of materials, which, while being fire-
proof, may be moulded, or worked, or tooled after the manner of wood.
For this purpose, we prepare by crushing, carding and cleaning by mechanical
means the fibrous mineral crocidolite with which we incorporate or mix all or any
of the following substances according to the purpose to which our invention may
be applicable, namely:-caoutchouc, cellulose, stearine, paraffin wax, leather flock,
gelatine, starch, petroleum refuse, or glycerine, silicate of potash, silicate of soda,
or solidified oil.
For an absolutely fireproof composition we take for example by weight-About
40 parts crocidolite, 10 parts cellulose, 40 parts leather flock, 10 parts silicate of
soda, or silicate of potash, the whole being mixed, kneaded and incorporated by
any ordinary means now in use, and being then moulded into shape, or rolled into
sheets as may be required; or, we may take the pulp so made and, by the use of
moulds combined with great pressure, completely cover any and every kind of
woodwork, the said woodwork forming a core giving rigidity to the article so
treated, and which is rendered thereby completely uninflammable.
For another compound, we take about 50 parts crocidolite, 10 parts cleaned cow-
hair, 20 parts kaurie gum, 20 parts india rubber solution, the whole being thoroughly
well kneaded and rinsed in steam heated pans. The resulting mass is moulded or
passed through heated rollers, which may be either plain, or embossed so as to
form various patterns as may be desired. Our object in keeping the mass heated
is to drive off as much as possible of the volatile inflammable material, retaining
We do not
just sufficient to form a cementing or binding substance, therefor.
confine ourselves to the use of india rubber solution as an ingredient, as any of the
before mentioned gums or cements may be used, which, while being of a binding
or adhesive nature, will not burst into flame on the application of heat, or convey
flame over its surface, this compound being more particularly intended for wall
coverings.
For a compound from which may be made tubes or pipes for electric light
leads, insulators and for other purposes, we take about 40 parts crocidolite,
40 parts shellac, 20 parts cellulose the whole being mixed or kneaded in the ordinary
manner, and afterwards moulded into form either in one piece, or in sections as may
be desired.
For another compound for the like purposes we take 40 parts crocidolite, 20 parts
kieselguhr or infusorial earth, 20 parts finely ground mica, 20 parts gypsum, china
clay, or Portland cement.
We do not limit ourselves to the exact proportion of the several ingredients
above specified, nor to the use of all the ingredients given, as these may be variously
modified according to the purposes to which the compounds are to be applied.

We, GEORGE JAMES DAVIS, of Overton, Ormeley Road, Balham, in the County
of Surrey, Engineer, and EDWARD JONES, of 61 St. Mary Axe, in the City of
London, Mining Engineer, 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 :-
Our invention relates to the production of materials, which, while being water-
proof, may be moulded, or worked, or tooled after the manner of wood.
For this purpose, we prepare by crushing, carding and cleaning by mechanical
means the fibrous mineral crocidolite or other fibrous mineral or fire resisting
substances with which we incorporate or mix all or any of the following substances
according to the purpose to which our invention may be applicable, namely
caoutchouc, cellulose, stearine, paraffin-wax, leather flock, gelatine, starch, petroleum
refuse, or glycerine, silicate of potash, silicate of soda or solidified oil.

moulds combined with great pressure, completely cover any kind of woodwork,
which forms a core giving rigidity to the article and is rendered thereby completely
uninflammable.
For another compound we take about 50 parts crocidolite, 10 parts cleaned cow
hair, 20 parts kauric gum, 20 parts india rubber solution, the whole being thoroughly
well kneaded and mixed in steam heated pans. The resulting mass is moulded or
passed through between heated rollers, which may be either plain, or embossed so
as to form various patterns as may be desired. Our object in keeping the mass
heated is to drive off as much as possible of the volatile inflammable materials,
retaining just sufficient to form a cementing or binding substance therefor.
We do not confine ourselves to the use of india rubber solution as an ingredient,
as any of the before mentioned gums or cements may be used which, while being
of a binding or adhesive nature, will not burst into flame on the application of
heat, or convey flame over the surface of the compound which is more particularly
intended for wall coverings.

We do not limit ourselves to the exact proportions of the several ingredients
above specified, nor to the use of all the ingredients given, as these may be
variously modified according to the purposes to which the compounds are to be
applied.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
The manufacture of compounds suitable for coverings for floors, walls, ceilings,

page_text: tubes, mouldings and other like purposes by combining crocidolite with
agglutinating and other materials, substantially as herein described.
