Improvements in or connected with the Manufacture of Wall or
other Coverings, Artificial Leather, Electrical Insulators, Boxes,
and other articles from Vegetable Parchment.
1, AMEDEE WILBAUX of St. Gilles, Brussels in the Kingdom of Belgium,
Merchant do hereby declare the nature of this invention to be as follows:-
In the Specification of my Patent dated 28 October 1890 No. 17268 I have
described means for the production of a new product of manufacture from a
material known as vegetable parchment such a product being capable of industrial
application in many ways not before contemplated for this material such as for wall
and other decorations for boot and shoe materials, carriage building, harnessing and
hat manufactures book binding and other trades or for packing goods and natural
produce of any description, for light and flexible boxes for containing preserves
for example, electrical insulators, cases for fireworks, and for many other useful
purposes, and when combined with fabric such articles as machine driving straps,
machinery washers, bags for containing cement, phosphates, and the like.
In the aforesaid Specification I have stated that the vegetable parchment
which forms the base or vehicle of the new product is rendered non-hygrometric
by applying to one or both of its surfaces one or more layers of oil or oil colour
of a uniform consistency and softness, or of varnish and the like which will
combine with the vegetable parchment so as to form a product susceptible neither
to humidity nor drought. The vegetable parchment so treated forms the base or
vehicle as it does also in my further improvements about to be described for the
support of the oils, colors, and different varnishes used, but the vegetable parch-
ment being impermeable to fatty substances cannot be saturated as ordinary paper
would be, but on the contrary when treated according to my invention such a
combination is formed that oils, colors, varnishes, and the like make a body with
the vegetable parchment which gains qualities it did not before possess, the result
being a final product capable of being sized, of a complete imputrescibility imper-
meability to water and fatty substances, and regulated hygrometricity. Especially as
applied to paper hangings and other decorations generally those that could be
rolled up and conveyed to the places where they are required to be used, and
there rapidly fixed and without smell, is a problem which has been sought to be
solved for a number of years, and this problem I have solved, by utilizing
vegetable parchment as hereafter described and in such manner as to render it
peculiarly suitable as the base or vehicle for the support of oils, colors, and various
varnishes with which these materials will combine and make a body. The oils,
colors and varnishes used in combination with the base or vehicle, should be thin,
ductile, of the desired hygrometricity, impermeable to fatty matters, and water,
yielding or spreading under the action of a painter's knife, like a composition, the
combined product being capable of bearing the heat of stoves and the material
when finished capable of being stretched.
According to my invention I employ vegetable parchment as a base, support, or
vehicle, for oils, colors resins, varnishes, bitumens, gutta percha, and the like
rendering the vegetable parchment through the action thereon of the said materials,
a new product of manufacture suitable when treated by known means for wall
The
decorations or coverings, artificial leather, insulating materials and so forth.
materials are applied to the vegetable parchment either by coating the surface or
surfaces or by placing it in a bath containing the material or materials to be
combined with the vegetable parchment and brushing off the excess of materials.
Without limiting myself to the materials named, or to the proportions thereof.

page_text: given, have found for the purposes of my invention the following composition
suitable for use when treating the vegetable parchment according to my invention:
4 to 5 parts of liquid litharge
4 to 5 parts of glycerine
1 to 2 parts of petroleum.
In this mixture I dissolve some vegetable or animal wax, suet, stearine or other
equivalent material, mixed or not with colors, varnishes and the like.
Then I apply with brushes either mechanically or by hand this liquid composition,
on the vegetable parchment, or I make the vegetable parchment to pass through a
tank filled with the liquid composition and I remove the excess with rolls and
combined brushes, and I dry in hot rooms or open air.
When the vegetable parchment has been so coated or steeped it has lost the
defects which it before possessed as a material suitable for the purposes of my
invention when not so treated, so that when combined with the composition before
described or compositions of equivalent nature, a product is produced particularly
suitable for being decorated in any well known manner by printing on or otherwise.
The adhesion of the colors and varnishes on the vegetable parchment when they
have been coated or steeped or mixed with the above described composition, is such
that its character becomes totally changed, the composition so acts on the vegetable
parchment as to render the latter sizable which otherwise is completely impossible,
moreover, entirely changing its hygrometric qualities. .
The material manufactured according to this invention may be varied considerably
in thickness, and consequently in strength, according to the purposes to which it
is intended to be applied, vegetable parchment ranging from 25 grammes to
500 grammes the square metre. Moreover when a special strength is required to
be imparted to it, the vegetable parchment being made sizable by my invention, is
combined with fabric interposed between alternate layers or sheets of the vegetable
parchment, and this is the case when the material is for example to be used for
machine driving straps, cement and phosphate bags and so forth.
Vegetable parchment treated in the manner before described when dry is ready
to be decorated or ornamented with any desired pattern or design as fancy or taste
may dictate, regulated according to the purposes to which the material is intended
to be applied, and this done the final product is ready for the market. The material
treated in the manner before described may of course, if desired, be utilized for
some purposes, such as for wrappers, without being decorated by printing on or
otherwise.
When made into artificial leather it may be treated as described for that purpose
in the Specification of my Patent dated 28 October 1890 No. 17268.
Dated this 24th day of April 1891.

COMPLETE SPECIFICATION.
Improvements in or connected with the Manufacture of Wall or
other Coverings, Artificial Leather, Electrical Insulators, Boxes,
and other articles from Vegetable Parchment.
I, AMÉDÉE WILBAUX, of St. Gilles, Brussels, in the Kingdom of Belgium,
Merchant, 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 :-
In the Specification of my Patent dated 28th October 1890, No. 17268, I have
described means for the production of a new product of manufacture from a

page_text: material known as vegetable parchment, such a product being capable of industrial
application in many ways not before contemplated for this material, such as for wall
and other decorations, for boot and shoe materials, carriage building, harnessing,
and hat manufactures, book-binding, and other trades, or for packing goods and
natural produce of any description, for light and flexible boxes for containing
preserves for example, electrical insulators, cases for fireworks and for many other
useful purposes, and when combined with fabric, such articles as machine driving
straps, machinery washers, bags for containing cement, phosphates, and the like.
In the aforesaid Specification I have stated that the vegetable parchment, which
forms the base or vehicle of the new product is rendered non-hygrometric by applying
to one or both of its surfaces one or more layers of oil or oil colour of a uniform
consistency and softness, or of varnish and the like, which will combine with the
vegetable parchment so as to form a product susceptible neither to humidity nor
drought. The vegetable parchment so treated forms the base or vehicle, as it does
also in my further improvements about to be described, for the support of the oils,
colours, and different varnishes used; but the vegetable parchment being imper-
meable to fatty substances, cannot be saturated as ordinary paper would be, but on
the contrary, when treated according to my invention, such a combination is formed
that oils, colours, varnishes, and the like make a body with the vegetable parch-
ment, which gains qualities it did not before possess, the result being a final product
capable of being sized, of a complete imputrescibility, impermeability to water and
fatty substances, and regulated hygrometricity especially as applied to paper
hangings and other decorations, generally those that could be rolled up and
conveyed to the places where they are required to be used, and there rapidly fixed,
and without smell, is a problem that has been sought to be solved for a number of
years; and this problem I have solved by utilizing vegetable parchment as here-
after described, and in such a manner as to render it peculiarly suitable as the base
or vehicle for the support of oils, colours, and various varnishes with which these
materials will combine and make a body. The oils, colours, and varnishes used in
combination with the base or vehicle should be thin, ductile, of the desired hygro-
metricity, impermeable to fatty matters and water, yielding or spreading under the
action of a painter's knife, like a composition, the combined product being capable
of bearing the heat of stoves, and the material when finished capable of being
stretched.
According to my invention I employ vegetable parchment as a base, support, or
vehicle for oils, colours, resins, varnishes, bitumens, gutta-percha, and the like,
rendering the vegetable parchment, through the action thereon of the said materials,
a new product of manufacture, suitable when treated by known means for. wall
decorations or coverings, artificial leather, insulating materials, and so forth. The
materials are applied to the vegetable parchment either by coating the surface or
surfaces or by placing it in a bath containing the material or materials to be
combined with the vegetable parchment, and brushing off the excess of such
materials.
Without limiting myself to the materials named, or to the proportions thereof
given, I have found for the purposes of my invention the following composition suitable
for use when treating the vegetable parchment according to my invention :-
4 to 5 parts of liquid litharge
4 to 5 parts of glycerine
1 to 2 parts of petroleum.
In this mixture I dissolve some vegetable or animal wax, salt, stearine, or other

page_text: defects which it had before possessed as a material suitable for the purposes of my
invention, when not so treated, so that when combined with the composition before
described, or compositions of equivalent nature, a product is produced particularly
suitable for being decorated in any well-known manner by printing on or otherwise.
The adhesion of the colours and varnishes on the vegetable parchment, when they
have been coated or steeped or mixed with the above described composition, is such
that its character becomes totally changed; the composition so acting on the
vegetable parchment as to render the latter sizeable, which otherwise is completely
impossible, moreover entirely changing its hygrometric qualities.
The material manufactured according to this invention may be varied con-
siderably in thickness, and consequently in strength according to the purposes to
which it is intended to be applied, vegetable parchment ranging from 25 grammes
to 500 grammes the square metre. Moreover, when special strength is required to
be imparted to it, the vegetable parchment, being made sizeable by my invention,
is combined with fabric interposed between alternate layers or sheets of the
vegetable parchment, and this is the case when the material is for example to be
used for machine driving straps, cement phosphate bags, and so forth.
Vegetable parchment treated in the manner before described when dry is ready
to be decorated or ornamented with any desired pattern or design, as fancy or taste
may dictate, regulated according to the purposes to which the material is intended.
to be applied, and this done, the final product is ready for the market. The
material treated in the manner before described may of course, if desired, be
utilized for some purposes such as for wrappers without being decorated by printing
on or otherwise.
When made into artificial leather, it may be treated as described for that purpose
in the Specification of my Patent dated 28 October 1890, No. 17268.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The new material and commercial article composed of a combination of
vegetable parchment with compositions of litharge, glycerine, petroleum, and
dissolved wax, suet, stearine or other equivalent materials, so as to impart to the
base or vehicle of the product qualities it did not before possess, of imputrescibility
and impermeability to water and fatty substances, such product being utilized for
many useful purposes, all substantially as and for the purposes set forth.
2. A new product of manufacture, composed of a combination of vegetable
parchment with composition of litharge, glycerine, petroleum, and the like, having
dissolved in same, wax, stearine, or equivalent materials, forming when applied on
the said vegetable parchment, a new and indissoluble body with it, and the colours
or varnishes coated on or mixed in the composition, giving a final product having
all the qualities common to vegetable parchment, giving it strength, imputrescibility,
impermeability to fatty substances, not dilutable by water, and in addition to these
qualities, the product is readily sizeable, waterproof, capable of being regulated
hygrometrically according to requirements, may be strengthened by fabric or fitted
to any surface to be covered, all substantially as and for the purposes herein
described.
