COMPLETE SPECIFICATION
Improvements in the Production of Electrotypes for the Purpose of
Producing Embossed Wall Paper, Leather, and Tapestry, and
Stamping Velvet, and for Embossing or Stamping other
Materials.
I, JOHN DENBY, of No. 4, Swinton Row, Edinburgh, in the County of Midlothian,
North Britain, Electrotyper and Stereotyper, 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 relates to improvements in the production of electrotypes for the
purpose of producing embossed wall paper leather and tapestry and stamping velvet
and for embossing or stamping other materials.
In accordance with my invention the electrotypes are produced either in the form
of cylinders or flat plates direct from wall paper, tapestry or leather or the said
cylinders or flat plates are produced as follows. The original pattern is made in
clay or other substance suitable for modelling and plaster casts are taken from the
same and deposited on.
I prefer to saturate the plaster casts with paraffin wax.
The whole pattern being reproduced in copper, and in two parts. Each part is then
placed in a casting box the exact size of the cylinder on which the pattern is to be
placed, then a mixture of lead and antimony is poured into the casting box, this
adheres to the back of the copper on which the pattern has been produced. You
then have the roller in two parts which require simply to be soldered together in
order to be ready for fixing on the cylinder of the machine.
For the reproduction of leather or wall paper and tapestry the original is saturated
with paraffin wax, stretched and fixed on a metal plate, and deposited on. In the
case of the wall paper it is backed, as in the case of the cylinders with stereotype
metal, but for the reproduction of leather the copper deposit is made around the
circumference of necessary cylinder. The two joints being brased, soldered at the
back, and the brass or iron cylinder also soldered, both are heated and the brass or
iron cylinder is inserted. The process for the reproduction of tapestry is the same
as the foregoing.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
The process for the production of electrotypes for the purpose of producing
embossed wall paper, leather and tapestry, and stamping velvet, and for embossing 5
or stamping other materials, substantially as hereinbefore described.
Dated this 10th day of January 1891.
