A New Nitro-cellulose Compound and Products Manufactured
therewith.
We WILLIAM VIRGO WILSON of Jubilee Street Mile End, in the County of
Middlesex, Colour Manufacturer and JOSEPH STOREY, of Lancaster in the County
of Lancaster, Manufacturing Chemist, do hereby declare the nature of the said
invention for A NEW NITRO-CELLULOSE COMPOUND AND PRODUCTS MANUFACTURED
THEREWITH to be as follows:-
This Invention relates to the production of a new compound consisting essentially
of nitro cellulose dissolved in acetate of amyl and amylic alcohol to which may be
added any of the known menstrua for nitro cellulose.
The solvent or solvents may be used in such proportion as to produce a liquid
having the consistency of varnish or only in sufficient quantity to convert the
nitro-cellulose into a stiff paste or dough, the preferred proportions in the respective
cases being,
Nitro cellulose
Acetate of amyl
Amylic alcohol
-
For stiff paste. For varnish.

The amylic alcohol employed is obtained from Faints a bye product in the
distillation of alcohol and known commercially as fusel oil.
This compound may be used for the decorative covering of metals, wood, leather,
fabrics, ordinary paper and especially papers used for decorative purposes, pictures,
photographs etc and is especially adapted for the manufacture of artificial leather,
leather cloth, fabrics in imitation of starched linen for the manufacture of collars,
cuffs, shirt fronts, vests etc. It may be applied directly for the above purposes by
any of the well understood modes of application or the said varnish or dough may
be further incorporated with any of the well known pigments or with such
vegetable and essential oils as have already been extensively used in combination
with nitro-cellulose.
The consistency of the substance will be dependent upon the proportions of the
several ingredients employed, but we have found the following additions to the

page_text: compound in the form of a stiff paste or dough as above specified to be very
suitable for the manufacture of artificial leather and leather cloth.
150 parts of castor or linseed oil,
100 parts of china clay or other pigmentary or colouring matter.
Essential oil of Birch or other aromatic body.
Tannic Acid.

For the coating of fabrics to be used for the manufacture of collars, cuffs etc
we add to the compound in the form of a stiff paste or dough as first above
specified.
75 parts of castor or linseed oil.
125 of oxide zinc or other white pigmentary matter and
"
1 of Essential oil of Cassia or other aromatic body.

For the coating or varnishing of plain or decorative paper we add to the
compound in the form of a stiff paste or dough as first above specified 50 parts of
castor or linseed oil.
In every case the additional ingredients are roughly mixed with the compound
and the whole subsequently placed in a straining machine or sieve or a masticating
machine or grinding rolls to which the application of heat is advantageous whereby
the mass is rendered homogeneous and ready for use. This mass may be then
spread upon fabrics, webs or paper for the purposes named.
We find the machines best adapted for this purpose are those commonly used for
spreading india rubber and gutta percha upon fabrics and webs in a manner now
well understood.

We WILLIAM VIRGO WILSON of Jubilee Street in the County of Middlesex
Color Manufacturer and JOSEPH STOREY of Lancaster in the County of Lancaster
Manufacturing Chemist do hereby declare the nature of this invention for
"A NEW NITRO-CELLULOSE COMPOUND AND PRODUCTS MANUFACTURED THEREWITH "
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 production of a new compound consisting essentially
of nitro-cellulose dissolved in acetate af amyl and amylic alcohol.
The solvent or solvents may be used in such proportion as to produce a liquid
having the consistency of varnish or only in sufficient quantity to convert tho
nitro-cellulose into a stiff paste or dough, the preferred proportions in the respective
cases being:

150 parts 400 parts.
The amylic alcohol employed is obtained from Faints, a bye-product in the
distillation of alcohol, and from potatoes, and is known commercially as fusel oil.
This compound, as a varnish, may be used for the decorative covering of wood,
leather, fabrics, ordinary paper and especially papers used for decorative purposes,
pictures, photographs etc, and as a stiff paste is especially adapted for the manu-
facture of artificial leather, leather cloth, fabrics in imitation of starched linen for
the manufacture of collars, cuffs, shirt fronts, vests etc. It may be applied directly
for the above purposes by any of the well understood modes of application, or the
said varnish or dough may be further incorporated with any of the well known
pigments, or with such vegetable and essential oils as have already been extensively
used in combination with nitro-cellulose.
We do not confine ourselves to the particular proportions above mentioned for
the nitro-cellulose, acetate of amyl, and amylic alcohol, nor to any particular
proportions or combinations of the pigmentary and oily matters added to the
compound.
We have found the following additions to the compound in the form of a stiff
paste or dough as above specified to be very suitable for the manufacture of
artificial leather and leather cloth :-
150 parts of castor or linseed oil,
100 parts of china clay or other pigmentary or colouring matter.

we add to the compound, in the form of a stiff pasto or dough as first above

125 parts of oxide zinc or other white pigmentary matter and
1 part of Essential oil of Cassia or other aromatic body.
For the coating or varnishing of plain or decorative paper we add to the
compound in the form of a stiff paste or dough, as first above specified, 50 parts of
castor or linseed oil.
In every case the additional ingredients are roughly mixed with the compound
and the whole then placed in a straining machine, masticating machine or grinding

upon fabrics and webs in a manner now well understood.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, we declare that what
we claim is
1st A compound consisting essentially of nitro-cellulose dissolved in, or combined
with, acetate of amyl and amylic alcohol, with or without the addition of diluent
and pigmentary matters as specified.
2nd As a new article of manufacture, a fabric or web coated with a compound
consisting essentially of a residuum of nitro-cellulose from a solution of the same in
acetate of amyl and amylic alcohol (fusel oil) with or without the addition of a
diluent or emollient and pigmentary matter as specified.
