page_text: LETTERS PATENT to John Harringtou, of No. 1, Cambridge Villa,
Swanmore Road, Ryde, in the Isle of Wight, and William Francis
.. Richards, of Birmingham, in the County of Warwick, Merchant, for
the Invention of "IMPROVEMENTS IN PRODUCING IMITATION MOROCCO OR
OTHER LEATHER OR RAISED DESIGNS ON CLOTH, PAPER, OR OTHER FLEXIBLE
FABRIC OR TISSUE."
Sealed the 1st March 1872, and dated the 26th September 1871.
PROVISIONAL SPECIFICATION left by the said John Harrington and
William Francis Richards at the Office of the Commissioners of
Patents, with their Petition, on the 26th September 1871.
WC, JOHN HARRINGTON of No. 1, Cambridge Villa, Swanmore Road,
Ryde, in the Isle of Wight, and WILLIAM FRANCIS RICHARDS, of
Birmingham, in the County of Warwick, Merchant, do hereby declare
the nature of the said Invention for " IMPROVEMENTS IN PRODUCING

page_text: IMITATION MOROCCO OR OTHER LEATHER OR RAISED DESIGNS ON CLOTH, PAPER,
OR OTHER FLEXIBLE FABRIC OR TISSUE," to be as follows:-
Our Invention consists of improvements on an Invention for which
Letters Patent were granted to John Harrington (one of the present
applicants) on the 14th day of January 1871, No. 109; and our
Invention consists of the improvements herein-after described in the
compositions employed in producing the said imitation morocco or
other leather or designs, and in the subsequent treatment of the said
leather or designs.
We conduct the manufacture of the said imitation leather or designs
in the following manner :-We employ a composition consisting of one
pound of glue and five liquid ounces of glycerine. The glue is steeped
and dissolved in as little water as will suffice to dissolve it on the
application of heat. To this mixture of glue and glycerine the required
colouring matter to give the desired colour is added. Where great
flexibility in the leather or design to be produced is required we add to
the ingredients enumerated 10 ounces of boiled linseed oil; and where
elasticity is required we add a small quantity of india-rubber dissolved
by boiling it in raw or boiled linseed oil. Or we add a small quantity
of a solution of india-rubber in any of its well known solvents. This
composition is spread while hot upon cloth or other fabric or tissue, and
while still hot is impressed with the electrotype or other mould taken
from the morocco or other leather to be imitated, or with a mould or
plate or surface having upon it the design to be produced. The
required pressure may be given by rolls or otherwise, or the electrotype
or other mould or plate having the design upon it may form one of the
rolls. Or the composition while hot may be spread on the fabric or tissue
by rolls or otherwise, so as to form a perfectly flat layer, and allowed to
cool and solidify. The plain tissue may afterwards be softened by heat,
and impressed by moulds or rolls, as before described. The impressing
of the tissue may be effected, but less perfectly, without the aid of heat.
After the impressed surface has cooled and hardened, we treat it with a
solution of common alum or chrome alum or other alum, or with a-
solution of sulphate of iron or of sulphate of copper, or of sulphate of
zinc. Either of these solutions may be applied to the surface of the
impressed composition and fabric or tissue by a brush or sponge, or the
impressed composition and fabric or tissue may be immersed for a short
time in either of the said solutions. In order to facilitate the action

page_text: of these solutions on the impressed surface the said surface may be
wetted with alcohol, or alcohol may be added to the solutions.
Although we prefer to apply the solutions described to the impressed
surface, yet the said solutions may be mixed with the composition before
it is spread upon the fabric or tissue. The treatment of the surface with
alum or the sulphates described and the incorporation of these sub-
stances with the composition prevent the tackiness of the surface, which
occurs when these substances are not used.
In order the more effectually to protect the impressed surface it
may be coated with copal or other varnish, or by a waterproof com-
position. The treatment with alum or like compounds may be dispensed
with, and the impressed surface protected by the application of copal
or other varnish, either plain or coloured. Before applying the varnish
to the surface we prefer to prepare the surface for the reception of the
varnish by rubbing it with a little French chalk. The impressed
surface may be ornamented by gold or other bronze or other colouring
material.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Harrington and William Francis Richards
in the Great Seal Patent Office on the 23rd March 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
HARRINGTON, of No. 1, Cambridge Villa, Swanmore Road, Ryde, in the
Isle of Wight, and WILLIAM FRANCIS RICHARDS, of Birmingham, in
the County of Warwick, Merchant, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of September, in the
year of our Lord One thousand eight hundred and seventy-one, in the
thirty-fifth year of. Her. reign, did, for. Herself, Her heirs and successors,
give and grant unto us, the said John Harrington and William Francis
Richards, Her special licence that we, the said John Harrington and
William Francis Richards, our executors, administrators, and assigns,
or such others as we, the said John Harrington and William Francis
Richards, our, executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times

page_text: thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "IMPROVEMENTS IN PRODUCING IMITATION MOROCCO OR OTHER LEATHER OR
RAISED DESIGNS on Cloth, Paper, OR OTHER FLEXIBLE FABRIC OR TIssue,” upon
the condition (amongst others) that we, the said John Harrington
and William Francis Richards, our exccutors or administrators, by an
instrument in writing under our or their hands and seals, or under
the hand and seal of one of us or them, should particularly describe and
ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the
Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Francis Richards, on
behalf of myself and the said John Harrington, 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 and by the
following statement thereof, that is to say:
Our Invention consists of improvements on an Invention for which
Letters Patent were granted to John Harrington (one of the present
Patentees) on the 14th day of January, A.D. 1871 (No. 109); and our
Invention consists of the improvements herein-after described in the
compositions employed in producing the said imitation morocco

leather or designs.
or
We conduct the manufacture of the said imitation leather or designs
in the following manner :-We employ a composition consisting of one
pound of glue and from five to seven liquid ounces of glycerine. The
glue is steeped and dissolved in as little water as will suffice to dissolve
it on the application of heat. To this mixture of glue and glycerine the
required colouring matter to give the desired colour is added. Where
great flexibility in the leather or design to be produced is required we
add to the ingredients enumerated ten ounces of boiled linseed oil; and
where elasticity is required we add a small quantity of a solution of
india-rubber in any of its known solvents. This composition is spread
while hot upon cloth or other fabric or tissue, and while still hot is
impressed with the electrotype or other mould taken from the morocco
or other leather to be imitated, or with a mould or plate or surface

page_text: having upon it the design to be produced. The required pressure may

having the design upon it may form one of the rolls. Or the com-
position while hot may be spread on the fabric or tissue by rolls or
otherwise, so as to form a perfectly flat, layer, and allowed to cool and.
solidify. The plain tissue may afterwards bo softened by heat and
impressed by moulds or rolls, as before described. The impressing of
the tissue may be effected, but less perfectly, without the aid of heat.
After the impressed surface has cooled and hardened we treat it with a
solution of common alum or chrome alum or other alum, or with a
solution of sulphate of iron or of sulphate of copper, or of sulphate of
zinc. Either of these solutions may be applied to the surface of the
impressed composition and fabric or tissue by a brush or sponge, or the
impressed composition and fabric or tissue may be immersed for a short
time in either. of the said solutions. In order to facilitate the action
of these solutions on the impressed surface, the said surface may be
wetted with alcohol, or alcohol may be added to the solutions.
Although we prefer to apply the solutions described to the impressed
surface, yet the said solutions may be mixed with the composition before
it is spread upon the fabric or tissue. The treatment of the surface
with alum or the sulphates described, and the incorporation of these
substances with the composition, prevent the tackiness or stickiness of
the surface, which occurs when these substances are not used.
In order the more effectually to protect the impressed surface it may
be coated with copal or other varnish, or by a waterproof composition,
either before or after it is grained or impressed. The treatment with
alum or like compounds may be dispensed with, and the impressed
surface protected by the application of copal or other varnish, either
plain or coloured. Before applying the varnish to the surface we prefer
to prepare the surface for the reception of the varnish by rubbing it
with a little French chalk. The impressed surface may be ornamented
by gold or other bronze, or other colouring material.
Having described the nature of our Invention, and the manner in
which the same is to be performed, we wish it to be understood that
we claim as our Invention the improvements in producing imitation
morocco or other leather or raised designs on cloth, paper, or other
flexible fabric or tissue herein-before described; that is to say, producing

page_text: the said imitation leather or raised designs by the use of the com-
positions and the process or combination of processes substantially as
described.

We conduct the manufacture of the said imitation leather or designs in
the following manner:-We employ a composition consisting of one
pound of glue, and from 5 to 7 liquid ounces of glycerine. The glue is
steeped and dissolved in as little water as will suffice to dissolve it on
the application of heat. To this mixture of glue and glycerine the
required colouring matter to give the desired colour is added. Where
great flexibility in the leather or design to be produced is required
we add to the ingredients enumerated ten ounces of boiled linseed
oil, and where elasticity is required we add a small quantity of a
solution of india-rubber in any of its known solvents. This com-
position is spread while hot upon cloth or other fabric or tissue, and
while still hot is impressed with the electrotype or other mould taken
from the morocco or other leather to be imitated,-or-with-a-mould or
