I WILLIAM NAPIER of 22 and 23 Bread Street Hill in the City of London
Printer do hereby declare the nature of my invention for IMPROVEMENTS IN
THE PROCESS AND MEANS EMPLOYED IN EMBOSSING PAPER AND OTHER MATERIALS "
to be as follows:-
This invention has for its object improvements in the process and means employed
to produce relief or sunk surfaces by the use of hot plates on various substances
such as paper wood pulp cotton fabric tin-foil paper leather or other suitable
materials and ornamenting such material to represent repoussé work, terra cotta
carved stone or pottery and other similar work for the purposes of advertising or
otherwise.
In carrying my invention into practise I first produce a carved wood block or
wax model of the required design either in relief or not and take from this an
ordinary copper or brass electrotype then to produce the sunk or female die (call
this No 2 die) throw or deposit surface of copper over N° 1 electro and back up
this die with lead in the usual way.
To form the male die I beat press or force paper of uniform thickness into N° 2
die and then mould lead into the back or beaten surface and by this means produce
the male or force die somewhat smaller than the female die to allow a thickness of
the material to be embossed to be introduced between the plates-and by this
process readily and cheaply produce a male or force die which is the exact counter-
part but on a smaller scale than the sunk or female die.
.
I now take a sheet of say millboard or pulp board of any suitable thickness
which sheet is damped and thinly covered with paste made from flour plaster of
Paris or other materials over this is laid any paper (colored or foil) according to
effect required-this combined board and paper is then placed between the plates
which plates are made hot by any suitable means as I find that the use of hot
plates gives sharp relief while also serving to dry the materials. These hot plates
are then pressed in any suitable press sufficiently to give the necessary relief.
The ornamentation of these embossed surfaces is of the usual process.

Paper and other Materials.
I WILLIAM NAPIER of 22 and 23 Bread Street Hill in the City of London
Printer 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 has for its object improvements in the process and means employed
to produce relief or sunk surfaces by the use of hot plates on various substances
such as paper wood pulp cotton fabric tin-foil paper leather or other suitable
materials and ornamenting such material to represent repoussé work cameo terra
cotta carved stone or pottery and other similar work for the purposes of advertising
decorating or other purposes.
In carrying my invention into practice I first produce a carved wood block or
wax model of the required design either in relief or intaglio and from this original
I take a plaster mould. Over this mould I deposit a thick surface of copper or
other suitable metal by the electrotype process and back up the same with lead in
the usual manner this gives me the female die (call this No 1 die) and which is the
reverse of the original carving or wax model.
My next proceeding is to cover the No 1 or female die with various thicknesses
of paper and composition and beat or force the same into its surface which in effect
is the same as the stereotyping process. I then mould lead into the beaten surface
of the paper and by this means readily and cheaply obtain a male or pressure die
(which is called No 2 die) and is an exact counterpart of No 1 die but on a smaller
scale the dimensions being regulated by the thicknesses of paper beaten into it.
I now have two plates and I take say a sheet of straw or wood pulp board felt
leather or other suitable material of the required thickness and slightly damp the
same and paste its surface with any suitable paste or adhesive material. I now lay
over this material colored paper foil or a printed or other sheet of paper of the same
design as the die according to the effect required. This combined board and paper
or other material I place between the two plates or dies which plates or dies are
made hot by any suitable means and are pressed in an ordinary Columbian printing
or other suitable press the result being an embossed surface showing the fullest
detail of the original carving.
The advantages of the embossed surfaces are the lightness and size as compared
with plaster casts the adaptability and cheapness of pulp board covered with
colored paper to ornamentation and being unbreakable under ordinary usage affords
unlimited means of imitating for advertising purposes or decorative uses repoussé
work cameo Wedgewood ware Majolica carved wood metal or stone. For decorating
the surfaces I use colors soluble in water in conjunction with gelatine glue size
varnish by which radiating shadows lights and shades and a variety of effects are
obtained.
I can produce a facsimile and imitation of any of the objects enumerated from
the size of one inch to thirty inches square and upwards at the same time the
largest weighing little exceeding 16 to 24 ounces.

page_text: The novel features of my invention consist in affording cheap and ready means
of producing a die and counterpart die of carvings in relief or intaglio that will
mould whether specially designed for the purpose or not of producing unlimited
facsimiles of the original.
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 improved means and process employed for producing a die and counterpart
die from carvings or other works in relief or intaglio for embossing paper and other
materials substantially in the manner and for the purposes herein before described.
