I, LOUIS PREAUBERT, of 27, Rue du Calvaire, Nantes (Loire-Inférieure), in
the Republic of France, Decorator and Paperhanger, do hereby declare the nature
of this invention to be as follows:-
This invention relates to an improved method for producing coloured wall-
hangings by applying to the outside thereof either as a whole or to a portion,
or portions, colours in the state of powder. But such powders are not applied
in the ordinary manner, that is to say by incorporating them in a size, oil, or
varnish or with any other liquid ordinarily used for mixing these colours with
a view to applying them with a brush or tor printing. My method permits of
applying the powdered colours in a speedy manner to any sort of coarse, rugose
fabric no matter how defective their outer appearance may be.
According to my invention I first cover the entire surface which the pannel
or the like is to have with one colour by the aid of a board, block or roller, by
hand or other means. The substance which is thus deposited by impression
with the aid of a block is a kind of size or varnish prepared from linseed-oil
for example, which is enabled to enter and fill up all the small cavities or recesses
in the fabric. When this is in a condition to properly retain the powdered
colours I dust the desired colour over the entire surface of the design previously
imprinted. The fabric however coarse, which on that account has not been
uniformly impressed, receives the powdered colour over the whole extent of the
design and this powder is then retained by the mordant or size i.e. the boiled
oil previously applied, so forming in a short time a paint which solidly adheres
to the fabric. After the whole has become thoroughly dry it suffices to brush
and wash off the excess of powder from the material.
By making several successive impressions with different blocks for imprinting
with size or boiled-oil various parts of a design which it is desired to produce,
designs may be obtained of any desired colours and as different from each other
as may be desirable, or the colours may be blended one with the other, the
workman who applies the pulverulent material distributing the powdered colours
upon the impressed foundation so as to obtain the desired blended or other
characteristic effects.
If it is desired to bring into relief the outlines of the design in order to cause
it to stand out from its foundation colour, I can still use the same means for
marking these outlines for showing certain hollows, or ribs in different colours,
that is to say I use a block to print the outlines, borders, ribs and the like with
size upon the previously applied paint; these are then dusted over with the

page_text: desired powdered colour and thus reproduce the work of an artist whether in
uniform or in various tints.
Thus as I have explained this method is especially applicable to coarse fabric
but of course it may also be applied to fine woven materials as well as to leather,
paper or metal. Or the fabric may be furnished with a very thin tin-foil
attached to it by means of varnish or by other suitable means. By using a
coloured varnish as is well known the metal is given an aspect of gold or silver
foundation or background upon which the tints are then produced by means of
the powdered colours in the manner hereinbefore described.
The fabric may be given a metallic appearance, gold or silver without the use
of tin foil. For instance coarse fabric for frieze with a golden background which
is covered with a colour which is afterwards wiped off so as to show the grain
of the fabric.
The designs produced by the powdered colours as before described may
represent leaves flowers, ornamental designs, figures and so on of any desired
shape or proportion as may be desired by the artist or originator of the design;
the workman need only distribute the powdered colours upon the size in
accordance with the original design or sketch, whether in flat tints shaded or
graduated tints, in order to reproduce the effect of the original.

Improved Method for the Production of Coloured Wall-hangings for
the Decorating of Apartments and for other purposes.
1, LOUIS PREAUBERT, of 27, Rue du Calvaire, Nantes (Loire-Inferieure), in
the Republic of France, Decorator and Paperhanger, 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: - -
This invention relates to an improved method for producing coloured wall-
hangings by applying to the outside thereof either as a whole or to a portion,
or portions, colours in the state of powder. But such powders are not applied
in the ordinary manner, that is to say by incorporating them in a size, oil, or
varnish or with any other liquid ordinarily used for mixing with a view to applying
them with a brush or for printing. My method permits of applying the powdered
colours in speedy manner to any sort of coarse fabric, no matter how defective
their outer appearance may be.
According to my invention I first cover the entire surface which the panel
or the like is to have with one colour by the aid of a board, block or roller, by
hand or other means. The substance which is thus deposited by impression
with the aid of a block is a kind of size or varnish prepared from linseed-oil
for example, which is enabled to enter and fill up all the small cavities or recesses
in the tabric. When this is in a condition to properly retain the powdered
colours I dust the desired colour over the entire surface of the design previously
imprinted. The fabric however coarse, which on that account has not been
uniformly impressed, receives the powdered colour over the whole extent of the
design and this powder is then retained by the mordant or size i.c. the boiled

page_text: oil previously applied, so forming in a short time a paint which solidly adheres
to the fabric. After the whole has become thoroughly dry it suffices to brush
and wash off the excess of powder from the material.
The following are the proportions and method of making and using the size
or varnish referred to above: –
Varnish
referred LO DOve.―
Concentrated oil or boiled oil
Ground white lead
Litharge
-
70%
25%
5%
The whole of these ingredients are intimately mixed together in a vessel over
a fire.
When thoroughly mixed the mass is allowed to cool, and is then spread
evenly upon a skin or other suitable surface, and the matrix for printing the
design is applied thereto. This matrix, when applied to the fabric which it is
desired to decorate, deposits the size or varnish.
The powdered colours are deposited upon the size by means of a sieve divided
into as many compartments as there are colours to be produced. The sieve is
agitated so as to cause the colour to be deposited upon the size, and so form the
desired designs.
By making several successive impressions with different blocks for imprinting
with size or boiled-oil various parts of a design which it is desired to produce,
designs may be obtained of any desired colours and as different from each other
as may be desirable, or the colours may be blended one with the other, the
pulverulent material being distributing upon the impressed foundation so as to
obtain the desired blended or other characteristic effects.
If it is desired to bring into relief the outlines of the design in order to cause
it to stand out from its foundation colour, I can still use the same means for
marking these outlines for showing certain hollows, or ribs in different colours,
that is to say I use a block to print the outlines, borders, ribs and the like with
size upon the previously applied paint; these are then dusted over with the
desired powdered colour and thus reproduce the work of an artist whether in
a uniform or in various tints.
This method is thus especially applicable to coarse fabric but it is obvious that
it may also be applied to fine woven materials or to leather, paper or metal. The
fabric may if desired be furnished with a very thin tinfoil attached to it by means
of varnish or by other suitable means. By using a coloured varnish as is well
known the metal is given an aspect of gold or silver foundation or background
upon which the tints are then produced by means of the powdered colours in the
manner hereinbefore described.
The fabric may be given a metallic appearance, such as of gold or silver, without
the use of tinfoil. For instance coarse fabric with a golden background may be
covered with a colour which is afterwards wiped off so as to show the grain
of the fabric.
The designs produced by the powdered colours as before described may
represent leaves, flowers, ornamental designs, figures or the like of any desired
shape or proportion as may be desired. The powdered colours need only be dis-
tributed upon the size in accordance with the original design or sketch, whether
in flat tints shaded or graduated tints, in order to reproduce the effect of the
original.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. The method of producing wall-hangings from fabrics, papers, leathers, paste-
boards, metal sheetings and the like by first printing upon the surface, whether
creased or smooth and covered or not with a tinfoil fixed on by means of size
or other suitable glue or varnish, the design to be reproduced, in a suitable size
or varnish and then dusting over with colour in state of powder, the design thus

page_text: formed by the adhesive substances so causing the colours to adhere strongly upon
the fabric forming the foundation substantially as described.
2. The herein before described process of producing canvas, gauze, leather,
paper, paste-board, metal sheeting and the like printed and painted with ground
colours as a smooth design or shaded, graduated or blended by the aforementioned
method.
