We, ALEXANDRE DE PONT of Bare, in the County of Lancaster Manufacturer and
SILVIUS DE PONT of Bare aforesaid, Manufacturer do hereby declare the nature
of this invention to be as follows:-
The object of this invention is to produce articles of an elastic or flexible
nature capable of withstanding the action of boiling water and not affected
sensibly either by heat or cold.
These articles may be prepared either in bulk of any degree of density by
heating and compressing the compound in a mould or in the form of a flexible
fabric by impregnating or coating a woven material therewith.
In carrying out the invention we employ waste vegetable materials such as
wood or sawdust cotton linen or other fibres or other suitable material to produce
a cellulose soluble in methyl alcohol or other solvent. With this soluble cellulose
we mix a quantity of a suitable gum such as mastic, copal, demar or the like;
a suitable vegetable or animal oil such as castor palm glycerine etcetera and a
suitable solvent such as methyl, methyl-alcohol, methyl or sulphuric ether or
naphtha. To this compound may be added pigments dyes or colouring matter
to produce any colour or shade.
For producing a solid elastic article or a compound from which such articles
can be made we mix with the above described compound any suitable compounds
such as sawdust bone dust waste fibres or other suitable materials which are
mixed or saturated with the cellulosic compound and then subjected to heat and
pressure in hydraulic or other press or mould and then allowed to gradually cool.
The soluble cellulose and gums are preferably dissolved and mixed together
first and then added to the other materials but if desired the dry materials may
be first mixed and then solvents and other liquids subsequently added.
When a flexible material is required the compound is spread over the surface
of a woven fabric paper or the like by which flexible waterproof fabrics and wall
papers or decorations can be produced such fabrics may be used for floor coverings
artificial leather upholstering or like purposes. The fabric when coated is stoved
and subjected to a temperature of about 220° which renders the material insoluble
and non-inflammable.
The essential feature of the invention is the preparation of elastic or flexible
articles comprising soluble cellulose with suitable gums and solvents mixed with
or applied to solid materials either in the form of powder or dust or in the form
of woven fabrics.

Improvements in the Manufacture of Plastic, Flexible, Elastic, and
other Articles.
We, ALEXANDRE DE PONT of Bare, in the County of Lancaster Manufacturer and
SILVIUS DE PONT of Bare aforesaid, Manufacturer, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
The object of this invention is to produce articles of an elastic or flexible nature
capable of withstanding the action of boiling water and not affected sensibly
by heat or cold, and' which may be employed in the preparation of such articles
as knife handles or other solid articles waterproof fabrics, artificial leather floor
coverings, wall papers and other articles.
These articles may be prepared either in bulk of any degree. of density, by
heating and compressing the compound in a mould or in the form of a flexible
fabric by impregnating or coating a woven material therewith.
In carrying out the invention, we take soluble cellulose made from vegetable
materials, such as wood or wood sawdust, cotton, linen or other fibres or other
suitable material. With this soluble cellulose we mix' quantity of a suitable
vegetable or animal oil, such as castor oil, palm oil or glycerine, and we dissolve
it in a suitable solvent such as methyl, methyl-alcoliol, methyl or sulphuric
ether or naphtha. A suitable gum may also be added such as gum mastic, copal,
damar, or the like, and the necessary pigments, dyes or colouring matter to
produce any desired colour or shade. This compound is then mixed with solid
materials in the form of powder or dust or applied to woven fabrics or paper
according to whether a solid or a flexible material is required.
..
To produce a solid, elastic material suitable as a substitute for artificial, ivory,
coral or the like, for the manufacture of knife handles, pianoforte keys, buttons
beads or other articles, we add to the mixture of soluble cellulose,. with the oil
or glycerine, a powdered solid material or materials, such as bone dust, phosphate
of lime, sawdust waste fibres or other suitable materials. These are thoroughly
incorporated with the cellulosic compound and the mass subjected to heat and a
high degree of pressure in suitable hydraulic or other press and moulds, and then
allowed to gradually cool.
The soluble cellulose and gums are preferably dissolved and mixed together
first, and then added to the other materials, but if desired, the dry materials may
be first mixed and then, solvents and other liquids subsequently added.
Suitable proportions of the several substances to prepare a solid material,
applicable as an ivory substitute, are as follows:-
Soluble cellulose
Palm oil, Castor oil, Glycerine or other suitable oil
Phosphate of lime
Bone dust, sawdust, or other powdered material
Sundry pigments such as magnesia barytą zinc-oxide,
.Gum
alumina
Aniline or other dyes may also be added.

It is to be understood that the proportions may be varied, and the gum may
be altogether omitted. The amount of solvent to be added may amount to 25%
or 30% of the mixed mass, sufficient being required to reduce it to a plastic
condition. ** »

When a flexible material is required, the compound is spread over the surface
of a woven fabric, paper or the like by which flexible waterproof fabrics and wall
papers or decorations can be produced, such fabrics may be used for floor coverings,
artificial leather upholstering or like purposes.
Suitable proportions of the several substances to prepare a flexible material
applicable for upholstery are as follows.

These proportions may be varied to suit different purposes, and the amount of
gum may be reduced or omitted. The quantity of the solvent should be sufficient
to reduce the compound to a soft dough or to a very plastic condition, so that
it may be spread upon a fabric or paper by an ordinary spreading machine, or
it may be reduced to a liquid or semi-liquid consistency to saturate the material.
Any number of coats of the material may be spread in succession to give the
desired thickness, and the material after being spread, may, when nearly dry, be
passed between rollers to give the desired amount of compression
The fabric when coated may be stoved and subjected to a temperature of about
220° F which renders the material insoluble and non-inflammable.
Finally the fabric may be calendered and embossed in any ordinary way.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed we declare that what we
claim is:
1. A solid elastic or flexible material, consisting of soluble cellulose dissolved
in suitable solvents and mixed with solid powdered materials, such as phosphate
of lime, bone dust, sawdust and the like with or without the admixture of
suitable gums, substantially as described.
2. A flexible fabric consisting of soluble cellulose dissolved in suitable solvents
and coated upon a woven textile fabric, with or without the addition of suitable
gums and pigments, substantially as described.
3. An elastic or flexible material suitable as an ivory substitute, or for fabrics
for upholstery or floor coverings, comprising soluble cellulose gums and solvents,
mixed with solid powdered substances or spread upon a woven fabric, substantially
as described.
