PROVISIONAL SPECIFICATION left by François Magny at the Office
of the Commissioners of Patents, with his Petition, on the 6th
August 1874.
I, FRANÇOIS MAGNY, of Boulevard de Strasbourg, 28, at Paris,
Ornamental Painter, do hereby declaro the nature of the said Invention
for "IMPROVEMENTS IN THE IMPERMEABLE FABRICS OR HANGINGS FOR WALLS AND
OTHER, DECORATIVE PURPOSES," to be as follows:
The object of my Invention is a kind of decorative painting in
imitation of wood, marble, and indeed of all decorativo objects in
general. This painting is effected upon paper and can be prepared with
or without a lining of tin either in powder or in sheet.
I proceed to describe the different methods of preparing this paper.
1. To preparo decorative painting upon paper in rolls I take light or
vegetable paper, stretch it upon any surface and spread upon it a layer
of gum arabic which it then dried. When the drying is complete. ther
decorative painting is effected by the hand or mechanically in oils above
the layer of gum, so as to imitate marble, wood, or any decorative
design; the paint is then dried and a layer of a single colour, the tint of
-

page_text: which is in relation to the wood, marble, or other object which it is
desired to imitate is laid over the whole. When this back layer is well
dried the painted paper is placed upon rollers, and these rollers of
decorative painting are applied to walls, doors, woodwork, &c., by
means of glue, which is either laid upon the surface to be covered or 5
upon the back layer which constitutes the reverse side of a roll of tho
painting. When the glue is dry the paper is moistened on to the wall
by means of a wet sponge or brush, so as to soak the first coating of
gum through the paper, and thus allow the latter to be easily removed
so as to leave the painting, alone. Thus the paper which served as a 1
medium is got rid of and there romains upon the wall or woodwork the
painting alone.
Secondly. To prepare decorative painting in rolls upon paper with a
lining of tin, either in powder or in shoot, the drying in the previous
process is dispensed with, and thus the risk of injuring the tone of the 1
colours is obviated, the rolling also can be effected immediately without
fear of sticking, and the decorativo painting can be used immediately.
In order to obviate the drying, the painting is made use of directly as
the fixing and glucing agent for the powdered or sheet tin.
The operation is as follows:-A light or vegetable paper glued or not, 2
or passed through paraffine or stearine or not, is taken and stretched
upon a table, a frame, a wall, or any surface whatever, to tho paper thus
stretched an isolating layer of more or less strong glue, gum, gelatine,
or other binding substance is applied and allowed to dry; a layer of
varnish or other fixing body is applied, and then after drying, the artistic 2
painting in oils is effected. Over this painting a general layer of oil
paint is laid, the shade of which varies according to the nature of the
decoration. This layer is allowed to become about two-thirds dry, and
upon the still moist layer powdered tin is spread by means of a supple
roller or a brush.
Instead of powdered tin sheet tin may equally well be employed, and
this is laid upon the moist layer of paint by means of an instrument of
wood or india-rubber or covered with cloth or velvet.

The employment of this painted paper lined with powdered or shoet
tin can be at once effected without artificial drying upon all walls, 3
woodwork, plaster, and other places.

page_text: It will be well to spread upon the wall or other place a layer of fatty
painting or mixture, or a waterproof glaze, which is only half dried
before the painted paper with the tin lining is applied thereto by a
moistened brush, sponge, or other implement.
When the painting is applied to the surface to bo covered its face is
washed to remove the paper which has served for a surface and which is
at the exterior. There thus only remains the painting upon powdered
or sheet tin.
