do hereby declare the nature of the said Invention for "IMPROVEMENTS.
IN THE MANUFACTURE OF PRESSED LEATHER," to be as follows:-
This Invention has for its object improvements in the manufacture.
of pressed leather. Pressed leather is made at present from curriers:
cuttings and other small pieces of leather by cementing them with paste
or glue, and pressing the pieces so prepared, and placed one on the
other into a sheet by a very heavy pressure. The sheets so prepared are.

become wet.
According to my Invention I render pressed leather waterproof by
applying to it by means of a brush or in other convenient manner
a composition consisting of,-

These materials are reduced to the proper consistence by the addition of
turpentine or other spirit.. In the process of boiling the oil caoutchouc
may be added to it. In place of minium other of the driers used by
painters may be employed. The composition should be applied when
the sheets of pressed leather are thoroughly dry and set. It is laid on
with a brush on one or by preference both of the surfaces of the pressed
leather, which then may be placed in a hot closet until the composition
becomes dry. Pressed leather thus prepared is especially applicable for
the insoles of shoes and boots.

NOW KNOW YE, that I, the said Eugenè Armand Alexis Hugo, 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

This Invention has for its object improvements in the manufacture of
pressed leather. Pressed leather is made at present from curriers
cuttings and other small pieces of leather by cementing them with paste
or glue, and pressing the pieces so prepared and placed one on the other
into a sheet by a very heavy pressure. The sheets so prepared are not
however waterproof, and are liable to fall in pieces should they become
wet.
According to my Invention I render pressed leather waterproof by
applying to it by means of a brush or in other convenient manner a
composition consisting of,-
Boiled linseed oil -
Resin
Minium

These materials are reduced to the proper consistence by the addition
of turpentine or other spirit. It is preferred in the process of boiling the
oil to add caoutchouc to it. I employ about four parts by weight of
caoutchouc to one hundred parts of oil. The caoutchouc is reduced to
small pieces, it is boiled in the oil, and when the boiling process is
complete it is thoroughly mixed up with the oil. In place of minium
other of the driers used by printers may be employed. The composition
should be applied when the sheets of pressed leather are thoroughly dry
and set. It is laid on by preference with a brush on one or both of the
surfaces of the pressed leather, which then may be placed in a-hot
closet or exposed in the open air until the composition becomes dry.

The leather should be coated in this manner several times.
leather thus prepared is applicable for the insoles of shoes and boots, for
heels, and other similar purposes.
In witness whereof, I, the said Eugenè Armand Alexis Hugo, have
hereunto set my hand and seal, this Eighteenth day of March,
in the year of our Lord One thousand eight hundred and seventy..
