We, HENRY REDMAYNE ROMNEY, of 50, Broadway, Crouch End, in the County
of Middlesex, Merchant; JAMES THAME, of 1, Devonshire Villas, The Wood-
lands, Isleworth, Surrey, Mining Engineer, and THE FIBROUS MATERIALS
SYNDICATE LIMITED, of 79, Gracechurch Street, in the City of London, Manu-
facturers, do hereby declare the nature of this invention to be as follows:-
This invention relates to the treatment and utilization of the dusty cellulose
and short fibre obtained as a waste product from the present operations for the
collection & utilization of bristle and mat fibres from the cocoa nut husk, and
which has heretofore been burnt or thrown away-and it consists in a process
whereby such dusty cellulose and short fibre, which it has hitherto not been
found possible to felt or pulp or work in any way, may be incorporated with
other cheap material to bind the same together in convenient portable form;
that is in slabs or sheets, which at the same time will retain in an eminent degree
the lightness, porosity and resilience of the said dusty cellulose or fibre.
To carry out our process we take the above mentioned refuse or waste, and
grade or size it by passing it thro' or over suitable screens, obtaining by this
means two or more classes of material viz.: comparatively long fibre, short fibre
and dust. The short fibre or dust we combine with any rough vegetable fibre,
capable of being reduced to a pulp. With this pulp we mix either in the beating
engine or chest from 30 to 70 per cent. of the short fibre or dust.
The long fibre we treat in the same way, but for certain applications such as
for packing between the hulls of battle ships we may combine a small quantity of
longer vegetable fibre such as old rope sacking or the like, the object in this
being to use a larger proportion of waste cocoa fibre or refuse so as to secure the
maximum resilience, and minimum weight.
To render either or both of these products partially or wholly impervious to
moisture we may add to the combined materials while same are in the beating
engine or chest a proportion of suitable sizing compounds say from 2 to 15 per
cent. of resin, turpentine, soap or other suitable size. We may also treat the
moulded sheets, slabs etc. in a solution of glue and fix same by passing through a
bath of tannic acid.
The material prepared as above, we next mould into sheets, slabs, blocks, or
other desired shapes, in moulds, covered with wire gauze, the moulded goods
being repressed in a hydraulic press, dried and where necessary rolled for finish.
We may also combine with the above asbestos dust or fibre to increase the
non-combustible nature of the material or may mix with same, fossil meal,
asbestos, whitening, colour, or other mineral to produce moulded articles for
walls, ceilings and the like.

page_text: We may also work the combined fibres as above described over a paper making
machine when it is required to produce a material in long lengths.
Material so produced is applicable for the following purposes, viz:-
Elastic floor covering.
Elastic roof covering.
Elastic jointing for steam joints.
Packing for use in battle ships.
Packing for use in refrigerators, either in ships or in cold storage buildings.
Non conductor for covering steam pipes and boilers:'
Roofing material for railway carriages, and for such other purposes where a
light elastic and non conducting material is required.
This material can also be used for many purposes for which cork is now used
being but 20 % heavier.

Improvements in Treating Waste Cocoa-nut Husk Dust, Fibre, or..
Refuse.
We, HENRY REDMAYNE ROMNEY, of 50, Broadway, Crouch End, in the County
of Middlesex, Merchant, JAMES THAME, of 1; Devonshire Villas, The Wood-
lands, Isleworth, Surrey, Mining Engineer, and THE FIBROUS MATERIALS
SYNDICATE LIMITED, of 79, Gracechurch Street, in the City of London, Manu-
facturers, 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 dusty cellulose
and short fibre of the husk of the cocoa nut, obtained as a waste product from
the present operations for the collection and utilization of bristle and mat fibres
from the said husk. Up to the present the dusty cellulose and short fibre has
been usually burnt or thrown away as a useless article.
This invention consists in a process whereby such dusty cellulose and short
fibre, (which it has hitherto not be found possible to felt or pulp or work up
in any way), is incorporated with other cheap material to bind the same together
in convenient portable form; that is in slabs or sheets, which at the same time
will retain in an eminent degree the lightness, porosity and resilience of the
said dusty cellulose or fibre in its natural state.
To carry out our process we take the above mentioned refuse or waste and we
combine with it any rough or vegetable fibre capable of being reduced to a pulp
in the proportion of 30 to 90% of fibre to 70 to 10 % of pulp according to the
class of material to be made.
This mixture is mixed thoroughly in a beating engine or chest of the usual
pattern and is subsequently moulded into sheets or slabs or other desired form
as hereinafter described. We may size or grade the said refuse or waste by
passing it through or over suitable screens obtaining by this means two or
more classes of material viz. :--comparatively long fibre, and short fibre with
dust.

page_text: The short fibre and dust is combined with any form of rough vegetable fibre
capable of being reduced to a pulp in the manner and proportion herein before
described:
The long fibre we treat in the same way, but for certain applications such as
for packing between the hulls of battle ships, we combine a small quantity of
longer vegetable fibre such as old rope, sacking or the like; the object in view
being to use a larger proportion of waste cocoa nut fibre or refuse so as to secure
the maximum of resilience with a minimum of weight.
To render either of these products partially or wholly impervious to moisture,
we add to the combined materials, for example while same are in the beating
engine or chest, a proportion of suitable sizing compounds, say from 2 to 15 %
of resin, turpentine, soap, or other suitable size.
Or, if desirable, we may apply the sizing compound after the combined
materials have been moulded or otherwise prepared. Or, we may equivalently
treat the material after moulding in a solution of glue and fix same by passing
it through a bath of tannic acid.
The material prepared as above described is next moulded into sheets, slabs,
blocks, or other desired shapes in moulds covered with wire gauze. The moulded
goods are then pressed in a power press, dried and when necessary rolled, for
obtaining a finished surface.
In order to make the finished material as non-combustible as possible we com-
bine with the material during the process of manufacture, abestos dust or fibre,
carbonate of magnesia, fossil meal, whitening, mineral colouring matter in the
proportion of 25 to 40% in volume. When the material is to be made in long
lengths, we work the composition over a paper making machine.
Material so produced is applicable for the following purposes viz.:—
Elastic floor covering as a substitute for carpet, felt or the like.
Do. roof do.
Do. jointing for steam and other joints.
Packing for use in battle ships.
Do. do. do. do. refrigerators either in ships or in cold storage buildings.
Moulded life buoys and other buoyancy apparatus.
Non conducting medium for covering steam boilers, pipes and the like.
Roofing material corrugated or otherwise for railway carriages and for such
other purposes, in which a light, elastic and non-conducting material is required,
or for use in combination with corrugated metallic sheets. When necessary the
material may be permeated with an oxidisable or drying oil or oils so as to
produce a substitute for linoleum or cork carpet having good wearing qualities
for use as floor cloths, mats or the like.
This material can also be used for many purposes for which cork is now used.
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. The process of treatment of cocoa nut dust, fibre or refuse with any vege-
table fibre that will pulp and the moulding of the said mixtures, substantially as
described.
2nd. In a process of treatment of cocoa nut dust, fibre or refuse, the grading
of the refuse, and the admixture of vegetable pulp with the fibres for making
a binding mixture and the addition thereto of longer fibres of old rope or sacking,
substantially as described.
