IMPROVEMENTS IN THE CHEMICAL TREATMENT OF CERTAIN HYDRO- CARBONS FOR THE PURPOSE OF HARDENING AND TOUGHENING THE SAME
Year: 1885

page_text: We, ROBERT PUNSION, of 17 Oriental Place, Brighton, in the County of Sussex,
Chemical Engineer, and SAMUEL HUSBANDS BECKLES, of 6 & 8 Lime Street
Square, in the City of London, Manufacturer do hereby declare the nature of our
invention for IMPROVEMENTS IN THE CHEMICAL TREATMENT OF CERTAIN HYDRO-
CARBONS FOR THE PURPOSE OF HARDENING AND TOUGHENING THE SAME, to be as
follows:-
Our invention consists in a method of hardening and toughening hydrocarbons
of a waxy nature, whereby such hydrocarbons become utilisable as a substitute for
indiarubber, gutta percha, ebonite, vulcanite, celluloid and other insulating or
waterproof and acid-resisting materials.
We carry our invention into effect by melting parts or thereabouts of the
hydrocarbon to be treated-which, preferably, is ozokerite-and then adding 1 part
or thereabouts of oxidised oil and 3 per cent or thereabouts of powdered sulphur.
The mixture is well incorporated by stirring and is allowed to remain at a tem-
perature of 200 degrees Fahrenheit or thereabouts until the required degree of
consistency is attained when it may be cast into moulds or applied as a coating
to any article or pressed into tubes or utilised in any other suitable manner.

We ROBERT PUNSHON of 17 Oriental Place, Brighton, in the County of Sussex,
Chemical Engineer, and SAMUEL HUSBANDS BECKLES, of 6 & 8 Lime Street
Square in the City of London Manufacturer do hereby declare the nature of our
invention for IMPROVEMENTS IN THE CHEMICAL TREATMENT OF CERTAIN HYDRO-
CARBONS FOR THE PURPOSE OF HARDENING AND TOUGHENING THE SAME and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
Our invention consists in a method of hardening and toughening hydrocarbons
of a waxy nature whereby such hydrocarbons become utilisable as a substitute for
indiarubber, gutta percha, ebonite, vulcanite celluloid and other insulating or
waterproof and acid-resisting materials.
.
We carry our invention into effect by melting 4 parts or thereabouts of the
hydrocarbon to be treated-which preferably is ozokerite-and then adding 1 part
or thereabouts of oxidised oil and 3 per cent or thereabouts of powdered sulphur.
The mixture is well incorporated by stirring and is allowed to remain at a
temperature of 200 degrees Fahrenheit or thereabouts until the required degree of
consistency is attained when it may be cast into moulds or applied as a coating to
any article or pressed into tubes or utilised in any other suitable manner.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
. 1. The process of hardening or toughening hydrocarbons of a waxy nature
substantially in the manner specified.
2. The application of such toughened or hardened hydrocarbons in substitution
for indiarubber, gutta percha, ebonite, vulcanite celluloid and other insulating or
waterproof and aoid-resisting materials.
