PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Imitation or Artificial
Leather.
I, HERMANN SCHMIEDEL, of VI, Fügergasse, 5, Vienna, in the Empire of
Austria, Manufacturer do hereby declare the nature of this invention to be as
follows:
This invention relates to the manufacture of imitation or artificial leather which
is suitable not only for binding books, but also, owing to its toughness, for the
manufacture of all fancy goods hitherto made of leather.
The improved process of manufacture is carried on as follows:-
--
A layer of linen or cotton fabric is firmly connected by gluing to a lining of
strong paper and afterwards provided with a coating made of water-colours
(white lead, chrome-yellow, ultramarine and the like) or of aniline colours, or of
lacquers dissolved in water and made of borax and shellac, or caseine, or tannin;
or it is coated first with water- or aniline colours, and then with lacquer. The said
operations can be performed either by hand or by machinery.
This imitation or artificial leather can be made smooth or figured; in the first
case the material, after being painted over and dried, is smoothed by means of
calenders; in the second case, it is run through goffering cylinders which press
any chosen pattern into the imitation or artificial leather.
'
As a matter of course, the said imitation or artificial leather can be given any
desired colour.

Improvements in the Manufacture of Imitation or Artificial
Leather.
I, HERMANN SCHMIEDEL, of VI, Fügergasse, 5, Vienna, in the Empire of
Austria, Manufacturer, 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 :—
This invention relates to the manufacture of imitation or artificial leather which
is suitable not only for binding books, but also, owing to its toughness, for the
manufacture of all fancy goods hitherto made of leather.
The improved process of manufacture is carried on as follows:-
A layer of linen or cotton fabric is firmly connected by gluing to a lining of
strong paper to form a base and is afterwards provided with a coating made from
water-colours, i.e. colours mixed or rubbed with water, such as white lead, chrome-
yellow, ultramarine and the like, or from aniline colours. The following example

proportions stated may be varied according to the particular colour selected and
to the circumstances of each particular case.
Gum shellac
Borax dissolved in water
Animal glue

The shellac in the above lacquer may, however, be replaced, in about the same
proportions, by tannin, albumen, caseine or the like. The proportions given may,
moreover, be varied as required. The said operations can be performed either by
hand or by machinery.
This imitation or artificial leather can be made smooth or figured; in the first
case the material, after being painted over and dried, is smoothed by means of
calenders; in the second case, it is run through goffering cylinders which press any
chosen pattern into the imitation or artificial leather, or it is embossed in any other
convenient manner.
As a matter of course, the said imitation or artificial leather can be given any
desired colour.
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. A process for the manufacture of imitation or artificial leather, which process
consists in gluing a linen or cotton fabric on strong paper, theu painting it over
with water-coloure, aniline colours or lacquer made of shellac dissolved in diluted
borax, or of tannin or caseine, or with mineral or aniline colours, and afterwards
with lacquer, then drying and finally calendering, goffering or embossing the
product, substantially as described.
2. As a new article of manufacture, imitation or artificial leather prepared
according to the process hereinbefore described.
Dated the 23rd day of January 1896.
