Improvements in Treating Waste Cocoanut Shells.
We, HENRY REDMAYNE ROMNEY, of 50, Broadway, Crouch End, in the County
of Middlesex, Merchant, and JAMES THAME, of 8, Ingleton Villa, Elthorne Road,
Uxbridge, in the County of Middlesex, Engineer, and THE FIBROUS MANU-
FACTURING COMPANY LIMITED, of 79, Gracechurch Street, in the City of
London, Manufacturers, do hereby declare the nature of this invention to be
as follows:
This invention relates to the treatment and utilization of the hard shell of
the cocoanut after the meat of the nut has been extracted.
Heretofore these shells have had no application of utility other than as a
low grade fuel.
To carry out our invention we grind up or disintegrate the pieces of shell
and screen to the required fineness by means of revolving or other suitable
screens.
The screenings are next mixed with a fibrous pulp obtained by reducing
vegetable or mineral fibre to a pulp in suitable beating engines or the like in
combination with water or other liquid.
The cocoanut shell dust or screenings may be mixed with the fibrous pulp
either while the same is being reduced or in a separate mixing vat provided
with revolving or other agitators.
The combined materials are then moulded in suitably shaped wire covered
moulds, re-pressed when necessary in felt covered moulds and finished when
required in polished metal moulds.
After moulding and drying, the articles so produced are treated in a bath
of any oxidizable or drying oil or oils. The said oil is thoroughly oxidized in
the body of the articles by drying at a temperature of 250° to 300° Fahr. The
said oil or oils may have added to it or them a suitable proportion of gums to
increase the hardness when required.
We may also combine with the mixture of fibrous pulp and cocoanut dust
any suitable cements such as magnesite, and magnesium, chloride, and zine
chloride, or any suitable colouring materials.
The approximate proportions we use for general work such as sheets, tubes,
and blocks, for electrical work are as follows:-
Fibrous nulu 25 ver cont.

page_text: rubber or rubber compounds sulphur etc., and vulcanize same in the usual way
the proportions for ordinary purposes being
Compounded rubber 25 per cent.
Cocoanut dust 75 per cent.

Improvements in Treating Waste Cocoanut Shells.
We, HENRY REDMAYNE ROMNEY, of 50, Broadway, Crouch End, in the County
of Middlesex, Merchant, and JAMES THAME, formerly of 8, Ingleton Villa,
Elthorne Road, Uxbridge, Middlesex, now of 1, Devonshire Villas, The
Woodlands, Isleworth, Surrey, Mining Engineer, and THE FIBROUS MANU-
FACTURING COMPANY LIMITED, of 79, Gracechurch Street, in the City of
London, Manufacturers, 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:-
This invention relates to the treatment and utilization of the hard shell of
the cocoa-nut after the meat of the nut has been extracted.
Heretofore these shells have had no applications of utility other than as a
low grade fuel.
To carry out our invention we grind up or disintegrate the pieces of shell
and screen to the required fineness by means of revolving or other suitable

The screenings are next mixed with fibrous material obtained by reducing
vegetable or mineral fibre in suitable beating engines or the like in combination
with water or other liquid.
The cocoa-nut shell dust or screenings may be mixed with the fibrous material
either while the same is being reduced or in a separate mixing vat provided with
revolving or other agitators.
The combined materials are then moulded in suitably shaped wire covered
moulds, repressed when necessary in felt covered moulds and finished when
required in polished metal moulds.
After moulding and drying, the articles so produced are treated in a bath of
any oxidizable or drying oil or oils.
The said oil is thoroughly oxidized in the body of the articles by drying at
a temperature of 2500-300° Fahrenheit. The said oil or oils may have added
to it or them a suitable proportion of gums, for example 10 to 30% of gum to
90 to 70% of oil, to increase the hardness when required.
We may also combine with the mixture of fibrous materials and cocoa nut
dust any suitable cements; such as magnesite, and magnesium chloride or zinc
chloride; and any suitable colouring materials.
The approximate proportions we use for general work such as sheet tubes and
blocks for electrical work are as follows:-
Fibrous materials 25 per cent.
Cocoa nut dust 75 per cent., and

page_text: 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;-
1st. A process for the manufacture of a new material consisting of the grinding
and screening of the hard shell of the cocoa-nut to a fine powder, the mixing of
the said powder with fibrous materials in combination with liquid, the moulding
of the mixture in a perforated mould, the drying of the moulded article and
subsequent treatment of same in a bath of any oxidizable or drying oil or oils,
substantially as described.
2nd. A new article of manufacture consisting of the hard shell of the cocoa-
nut finely powdered fibrous material and any oxidizable or drying oil or oils
manufactured in the manner and proportions,,substantially as described.
Dated this 19th day of May. 1899.
