AN IMPROVED FIXING COATING FOR MOROCCOS AND DYED LEATHER AND SKINS OF ALL KINDS
Year: 1884

page_text: PROVISIONAL SPECIFICATION,
I, WILLIAM EDWARD GEDGE of No 11 Wellington Street, Strand, London in
the County of Middlesex, Patent Agent do hereby declare the nature of my
invention for "AN IMPROVED FIXING COATING FOR MOROCCOS AND DYED LEATHER
AND SKINS OF ALL KINDS” to be as follows:-
To fix the colors of Moroccos and leather and skins of all kinds use has hitherto
been made of spirit or Ether Varnishes, and also of a kind of glue or size, These
various varnishes have the defect of protecting the colors but very imperfectly and
particularly of fading or changing when they are only wetted.
The coating the subject of this Invention and the composition of which I will
hereinafter describe, not only renders the colors indelible, but further permits their
being freely washed with water.
In future the interior of carriages, furniture, bindings, and sheaths or coverings,
in short all skins or leather coated by my process may be washed.
To fix the color and make dyed leather or skins of all kinds, and particularly
Morocco, supple, I have invented a conting of Linseed Oil cooked with Salts of
Lead (chloride of Lead) and of Manganese in the following proportions for 100.

The whole is cooked together according to the rules of the art, and after cooking,
the quantity of spirit is added which is deemed requisite for the use for which the
fixing coating thus obtained is intended.
By the aid of the said Coating the skins or leather become more supple and the
grain is nourished and can no longer crack or break.

for AN IMPROVED FIXING COATING FOR MOROCCOS AND LEATHER AND SKINS OF
ALL-KINDS and in what manner the same is to be performed, to be particularly
-described and-ascertained_in_and_by the following statement:=
To fix the colors of Moroccos and leather and skins of all kinds use has hitherto
been made of spirit or Ether varnishes, and also of a kind of glue or size. These
various varnishes have tho defect of protecting the colors but very imperfectly and
particularly of fading or changing when they are only wetted.
The coating the subject of this Invention and the composition-of-which I will
hereinafter describe, not only renders the colors. indelible, but further permits their
being freely washed with water. In future the interior of carriages, furniture,
bindings, and sheaths or coverings-in-short-all skins_or_leather coated by my
process may be washed.
To fix the color and make dyed leather or skins of all kinds, and particularly
Morocco, supple, I have invented a coating of linseed Oil cooked with salts of Lead
(chloride of lead) and of bi-oxyd of manganese in the following proportions for
100 kilogrammes, for example,
Lead
Manganese
Spirit of Turpentine

100 kilo³,
I add to the oil, in the above proportions, oxyd of Lead and bi-oxyd of Manganese
and cook until of a sirupy consistency taking care to often agitate the mass;'
towards the end of the cooking I take the boiler off of the fire and add the quantity
of spirit which is deemed requisite for the uso for which the fixing coating is
intended; I then heat again for a few minutes, but with great caution to avoid
setting the product on fire.
By the aid of the said Coating the skins or leather become more supple and the
grain is nourished and can no longer crack or break.
This product or fixing coating is applicable to dyed skins leather and Moroccos of
all kinds whether for furniture, carriages, binding sheath making or other uses.
This fixing coating may be applied upon the skins, leather, or Moroccos, by means
of a brush, as for example on blacking shoes, and then be dried at the Stove or
otherwise, if the first coating is insufficient a second may be applied in the same
manner.

page_text: 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
The above described product or fixing coating for Moroccos and dyed leather and
skins of all kinds,
