PROVISIONAL SPECIFICATION.
Improvements in the Treatment of Hemp, Flax, Jute, Cotton,
and other Substances, in order to Preserve the same.
I, EDWIN THOMAS TRUMAN, of 23, Old Burlington Street, in the County of Middlesex,
Surgeon, do hereby declare the nature of this invention to be as follows:-
It is known that certain oxides of manganese, lead, barium and copper, and more
particularly the peroxides of manganese and lead and the black oxide of copper,
have the property of decomposing ozone in practically unlimited quantities, and by
its decomposition converting it into pure oxygen, and I have found that the use of
these substances as applied to hemp, flax, jute, cotton and various other materials,
such for example as gutta percha, india rubber and wood, has the effect of preserving
them from oxidation or decay. The reason of this is, as I believe, that ozone is the
active agent in inducing gradual decay, and therefore its decomposition by the said
oxides on coming in contact therewith and its consequent conversion into pure
oxygen prevents decay or the so called oxidation of the materials to which such.
oxides are applied. My invention, therefore, consists in the employment of any one
or more of the oxides above referred to for the treatment of hemp, flax, jute, cotton
and other substances in order to preserve the same.
In employing these oxides for the preservation of hemp, flax, gutta percha, india
rubber or other materials I may mix them with ozokerit, tar or other vehicles
necessary or desirable for their utilization or application.
Among the purposes for which these substances can be employed with advantage
are the preservation of the materials used in the construction or laying of insulated
electrical conductors and cables.
The preservative substances are also beneficial if placed in the joint boxes of
underground conductors and they may be drawn into the tubes with the conductors
either in the form of powder or otherwise as experience may dictate. Or they may
be mixed with the jute or other packing used in the construction of compound
cables.
•
The preservative substances may also be used with advantage in the treatment of
sail cloths, tarpaulins or other fabrics, or of ropes, rordage &c.
The oxide which I prefer to employ for the purpose of my invention is the peroxide
or black oxide of manganese. But peroxide of lead, peroxide of barium, or black
oxide of copper will answer the purpose.

Surgeon, 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::

particularly the peroxides of manganese and lead and the black oxide of copper,
have the property of decomposing ozone in practically unlimited quantities and by

them from oxidation or decay. The reason of this is as I believe that ozone is the
active agent in inducing gradual decay and therefore its decomposition by the said
oxides on coming in contact therewith and its consequent conversion into pure oxygen
prevent decay or the so called oxidation of the materials to which such oxides are
applied. My invention therefore consists in the employment of any one or more of
the oxides above referred to for the treatment of hemp, flax jute, cotton and other
substances in order to preserve the same.
In employing these oxides for the preservation of hemp, flax, gulta percha, india
rubber or other materials I may mix them with ozokerit, tar or other vehicles
necessary or desirable for their utilization or application.
Among the purposes for which these substances can be employed with advantage
are the preservation of the materials used in the construction or laying of insulated
electrical conductors and cables.
The preservative substances are also beneficial if placed in the joint boxes of
underground conductors and they may be drawn into the tubes with the conductors
either in the form of powder or otherwise as experience may dictate. Or they
may be mixed with the jute or other packing used in the construction of compound
cables.
The preservative substances may also be used with advantage in the treatment of
sail cloths, tarpaulins or other fabrics, or of ropes, cordage etc.
The oxide which I prefer to employ for the purpose of my invention is the peroxide
or black oxide of manganese, but peroxide of lead, peroxide of barium or black oxide
of copper will answer the purpose. The proportion of oxide used can obviously vary
within very wide limits; speaking generally, the larger the proportion the better will
be the preservation.
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 treatment of hemp, flax, jute, cotton and other substances in order to preserve
the same with one or more of the following oxides substantially as hereinbefore
set forth, that is to say:--black oxide or peroxide of manganese, black oxide of copper,
peroxide of lead and peroxide of barium.
