TREATMENT OF REAL AND ARTIFICIAL OR IMITATION LEATHER."
"IMPROVEMENTS IN THE
The Invention has for its object improvements in the treatment of real leather,
and of that description of artificial or imitation leather which is made of paper,
and consists, firstly, in a mode of giving artificial or imitation leather a greater
body, and in making the back thereof have a great resemblance to the back of real
leather. For this purpose I apply to the back of the artificial or imitation leather
a coating of ground cork, ground wood or bark, or other similar material or ground
paper or papier maché, either alone or in combination with adhesive materials, so
as to make an elastic plastic compound thereof, and I apply these materials to the
back of the artificial or imitation leather by means of any suitable cement, by
preference an elastic cement. I would, however, state that I do not claim as my
Invention the employment of flock or other fibrous material for the purpose
stated.
In some cases in order to give a greater body to the artificial or imitation
leather I give more than one coating thereto of the powdered materials or elastic
plastic compound, employing a suitable cement between each coating.
My Invention relates, secondly, to a mode of preparing real leather in order to
enable it to retain any embossed design given thereto by blocks, dies, or rollers.
For this purpose I prepare the back of the leather in a similar manner to that
described with reference to the first part of my said Invention, as applied to the
back of artificial or imitation leather inade of paper, or I impregnate the back of
the leather with paste, glue, or other suitable cement, by preference using a semi-
elastic cement, and I allow the cement to become set or hard before embossing the
leather. By these means the leather is so strengthened that when embossed the
design is permanently retained thereon.

JOHN HARRINGTON, of Ryde, in the Isle of Wight. "IMPROVEMENTS IN THE
TREATMENT OF REAL AND ARTIFICIAL OR IMITATION LEATHER."
The Invention has for its object improvements in the treatment of real leather,
and of that description of artificial or imitation leather which is made of paper,
and consists, firstly, in a mode of giving artificial or imitation leather a greater
body or thickness, and in imparting to the back thereof a great resemblance to the
back of real leather. For this purpose I apply to tlie back of the artificial or
imitation leather a coating of ground cork, ground wood or bark, or other similar
material, or ground paper or papier maché, either alone or in combination with
adhesive materials, so as to make an elastic plastic compound thereof, and I apply
these materials to the back of the artificial or imitation leather by means of any
suitable cement, by preference an elastic cement. I would here state that I do not
claim as my Invention the employment of flock or other fibrous material for the
purpose stated.
In some cases, in order to give a greater body to the artificial or imitation
leather, I give more than one coating thereto of the powdered materials or elastic
plastic compound, employing a suitable cement between each coating, or when
using the elastic plastic compound enough may be applied to the back of the
artificial or imitation leather in a single coat.
My Invention relates, secondly, to a mode of preparing real leather in order to
enable it to retain any embossed design given thereto by blocks, dies or rollers.
For this purpose I prepare the back of the leather in a similar manner to that
described with reference to the first part of my said Invention as applied to the
back of artificial or imitation leather made of paper, or I impregnate the back of
the leather with paste, glue, or other suitable cement, by preference using a semi-
elastic cement, and I allow the cement to become set or hard before embossing the
leather. By these means the leather is so strengthened that when embossed the
design is permanently retained thereon.
Having thus described the nature of my said Invention, and the mode in which
I carry the same into effect, I would have it understood that what I claim is,-
Firstly. The mode of giving that description of artificial or imitation leather
which is made of paper a greater body, and of giving to the back thereof a greater
resemblance to the back of real leather, substantially as herein described.
And, Secondly. I claim the mode of preparing real leather, substantially as
herein described in order to enable it to retain any embossed design given thereto
by blocks, dies, or rollers.
In witness whereof, I, the said John Harrington, have hereunto set my hand
and scal, this Eighteenth day of July, in the year of our Lord One
thousand eight hundred and seventy-six.
JOHN HARRINGTON. (L.S.)
