A NEW INDUSTRIAL PRODUCT TO BE USED AS PANELS AND HANGINGS IN RELIEF to bu
Year: 1885

page_text: I MARIE LOUISE ADRIENNE BRESSAC of 34 Rue de Dunkerque Paris in the
Republic of France do hereby declare the nature of said Invention for A NEW
INDUSTRIAL PRODUCT TO BE USED AS PANELS AND HANGINGS IN RELIEF to bu̟ as
follows:-
•
Heretofore in the manufacture of different articles for hangings (stuff, paper or
leather) the reliefs have been obtained either by the application of these said
reliefs upon a smooth ground or surface or by the employment of cylinders
printing, by means of pressure, a subject in relief upon a soft or liquid surface
prepared and arranged previously for such purpose or again by goffering.
The process of manufacture, constituting the subject of my present invention
consists in forming simultaneously the ground and the reliefs, which cover it, by
means of a composition of which the base will be hereinafter described and which
allows of making a solid body consisting of different parts which constitute the
hanging.
In a word the fabric or any convenient material (such as leather paper or other
material) employed as ground is solid with the reliefs of this hanging.
For this manufacture I compound firstly a paste having a base of pitch, (poix)
animal glue, glycerine and tannin, the proportions of each of these materials may
be varied according to the degree of fluidity to be given to the paste, according
to the greater or less degree of flexibility which the hanging should possess
and also according to the nature of the decoration which the hanging is to
receive.
I then prepare a mould of the relief which I wish to obtain; I pour into this
mould the paste which has been previously prepared and the base of which
has been above described, taking care to apply at the same time and in proportion
as required the fabric which it ought to impregnate and which should serve to

page_text: strengthen or consolidate it. I then allow it to dry or cool, either naturally or
artificially so that the paste being literally consolidated to the design whilst
retaining its flexibility may also become sufficiently tenacious to keep the
impression which the mould has given to it.

and Hangings
in Relief.
I MARIE LOUISE ADRIENNE BRESSAC of 34 Rue de Dunkerque in the Republic
of France, do hereby declare the nature of the said .invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
Heretofore in the manufacture of different articles for hangings (stuff, paper or
leather) the reliefs have been obtained either by the application of these solid
reliefs upon a smooth or level ground or surface or by the employment of cylinders,
printing, by means of pressure, a subject in relief upon a plastic or liquid surface,
previously prepared and arranged for such purpose or again by goffering.
The process of manufacture constituting the subject of my present invention
consists in forming simultaneously the ground and the reliefs, which cover it, by
means of a composition of which the base or ingredients will be hereinafter
described and which allows of making a solid body consisting of the different
parts which constitute the hanging.
In a word the fabric or any convenient material (such as leather, paper or other
material) employed as the ground is solid with the reliefs of the hanging.
For this manufacture I compound firstly a paste having a base of pitch (poix)
animal glue in the form of size, glycerine, and tannin or in lieu of one or more
of the above named materials I may employ any suitable substitutes having a
somewhat similar or analogous effect upon the composition or I may add one or
more of such materials; for instance in lieu of tannin which has the effect of
rendering the gelatinous portions of the compound insoluble in water, I may
employ gum-lac which being itself insoluble in water acts by surrounding and
'enclosing the gelatinous particles to render them also insoluble in water. I may
1

page_text: also, in lieu of or in addition to glycerine, use linseed or other oil to impart a
certain degree of flexibility and elasticity to the product, the proportions of the
various materials may be varied according to the degree of fluidity to be given to
the paste, according to the greater or less degree of flexibility which the hanging
should possess and also according to the nature of the decoration which the
hanging is to receive.
I then prepare a mould of the relief which I wish to obtain; either upon a plane
ground or upon a cylinder; I pour into this mould when in a plane surface or
between a pair of cylinders when the mould is made upon a cylindrical surface;
the paste which has been previously prepared of the materials and in about the
proportions herein described, taking care to apply at the same time and in pro-
portion as required the fabric which should be impregnated with such paste and
which should serve to strengthen or consolidate it, I then allow it to dry or cool,
either naturally or artificially so that the paste being literally consolidated to the
design whilst retaining its flexibility may also become sufficiently tenacious to keep
the impression which the mould has given to it.
In the preparation of the composition or paste I employ one or other of the.
following formula.
1et
1 lb gelatine.
t Norway pitch.
23
Burgundy
"
"
Size (Animal glue).
Glycerine.
"
Tannin.
The above product is of dark color, it has great solidity and strength, it bends

page_text: If one or other of these products should be exposed either to the open air or to
a very great dampness, I add to each of these mixtures, tannin in powder, which
has upon the gelatinous ingredients, a chemical preserving action.
These materials are compounded by mixing them together in a vessel and
submitting them to the action of heat and stirring them until the said materials
are melted and combined.
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 process of manufacture herein described in its application to the product
stated.
2. The composition of the product itself made of the materials and in the
proportions substantially as herein described, the new kind of panels and hangings
in relief obtained by means of the process and compositions described, and for the
purpose stated.
