Improvements in the Manufacture of Moulds for the Use of
Confectioners and others.
I, JAMES GEORGE INGRAM, of The London India Rubber Works, Felstead
Street, Hackney Wick, in the County of London, India Rubber Manufacturer, do
hereby declare the nature of this invention to be as follows:-
The invention relates to that class of mould for the use of confectioners and
others which is made of india-rubber or other elastic material and is formed as a
shell or skeleton having any desired number of matrices formed thereon.
The usual method of producing these moulds is as follows; a plate has had fixed
on one or both sides thereof a number of patterns, and a sheet of pure india rubber
or of india-rubber compound is placed over these patterns and is caused to follow
the surface of the same by means of suction or pressure applied thereto either before
or during the vulcanizing process.
This process of manufacture is however expensive, not sufficiently exact in its
result and produces a mould irregular in substance..
According to my invention I can produce a shell or skeleton mould at a moderate
cost, of great exactitude and of the required regularity of substance.
For this purpose I employ a bath consisting of a solution of pure india-rubber or
india-rubber compound into which I dip the metal plate with the pattern or patterns
thereon a sufficient number of times to obtain the required substance, allowing the
solvent to be evaporated off after each dipping. When the required substance
of india-rubber or of india-rubber compound has been deposited on the pattern or
patterns, it is submitted to the ordinary vulcanizing process, after which the
mould is stripped from the patterns and is then ready for use.

page_text: The usual method of producing these moulds is as follows:-A plate has had
fixed on one or both sides thereof a number of patterns, and a sheet of. pure india
rubber or of india rubber compound has been placed over these patterns and
bas been caused to follow the surface of the same by means of suction or
pressure applied either before or during the vulcanizing process.
This process of manufacture is however expensive, not sufficiently exact in its
result and produces a mould irregular in substance.
According to my invention I can produce a shell or skeleton mould at a moderate
cost, of great exactitude and of the required regularity of substance.
A mould made according to my invention is represented in cross section in the
accompanying drawing.
In carrying my invention into effect I employ a bath consisting of a solution of
pure india rubber or india rubber compound into which I dip the before mentioned.
metal plate with the pattern or patterns thereon a sufficient number of times to
obtain the required substance, allowing the solvent to be evaporated off after each
dipping.
When the required substance of india rubber or of india rubber compound has
been deposited on the pattern or patterns, it is submitted to the ordinary
vulcanizing process, after which the mould is stripped from the patterns and is
then ready for use.
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 :-
1. A flexible mould for the use of confectioners and others made by dipping a
plate with the pattern or patterns thereon a requisite number of times in a solution
of india rubber or india rubber compound to obtain the desired substance,
substantially as herein described.
2.. A flexible mould for the use of confectioners and others made substantially in
the manner herein described.
