Chemist do hereby declare the nature of said Invention for "IMPROVEMENTS IN
THE PRODUCTION OF MATERIALS CAPABLE OF BEING EMPLOYED FOR PROTECTING
AND INSULATING PURPOSES to be as follows:-
"
ነ
My Invention consists in the employment of the following combination of
materials for insulating or protecting telegraphic or telephonic wires or other forms
of conductors of Electric or magnetic currents in about the proportions hereinafter
mentioned vizt from about 90 lbs of Asphaltum (by preference Egyptian or Persian)
or other good hard pitchy matter from about 5 lbs to about 10 lbs of Boiled Linsced
oil or of Castor Oil or Cotton Seed Oil.
Another useful combination may be made as follows :—
:
I employ about 90 lbs of Asphaltum about 5 lbs to about 10 lbs of Paraffin or of
Ozokerit. I have also found the following proportions to produce a useful mixture
or composition vizt-from about 90 lbs of Asphaltum and from about from 5 lbs
to about 10 lbs of Paraffin or of Ozokerit and from about 2 lbs to about 5 lbs of
either of the oils referred to or of mixtures of the same. Any or all these mixtures
may be produced by melting them together or by passing the mixture through
heated rolls or other means may be adopted and the product or composition thus
resulting may be applied to wire or to other forms of Electrical conductors as before
mentioned by any of the well known methods now employed for coating and
insulation whether the wires or other forms of Electrical Conductors be braided
or not.
The above proportions may be varied to make the material more suitable for
different kinds of Insulators and for the purposes for which Insulation is required
to be adopted, and there may be used in conjunction with the asphaltum such
materials as Japan wax or Steatite and also Oxide of zinc or other pigment.

I, ALEXANDER PARKES of 32 Park Road West, Dulwich in the County of Surrey,
Chemist do hereby declare the nature of my Invention for "IMPROVEMENTS IN
THE PRODUCTION OF MATERIALS CAPABLE OF BEING EMPLOYED FOR PROTECTING
AND INSULATING PURPOSES and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:-
"
My Invention consists in the employment of the following combination-of
materials for insulating or protecting telegraphic or telephonic wires or other forms-
of conductors of Electric or magnetic currents in about the proportions hereinafter
montioned vizt from about 90 lbs of Asphaltum (by preference Egyptian or Persian)
_ or other good. hard pitchy matter, from about 5 lbs to about 10 lbs of a driping Oil
such as boiled Linseed Oil or of Castor-oil,-or-Cotton seed oil.
Another useful.combination may be made as follows
I employ about 90 lbs of Asphaltum about 5lbs to about 10-lbs of. paraffin or
Ozokeritor Japan-or-Vegetable wax. I have also found the following proportions to
produce a useful mixture or composition viz: from about 90-lbs-of-Asphaltum_and_
from about from 5 lbs to about 10 lbs of Paraffin or Ozokerit or Japan or Vegetable
wax and from about 2 lbs to about 5 lbs of either of the Oils referred to or of
mixtures of the same. Any or all these mixtures may be produced by melting the
ingredients together or by passing them through heated rolls, or other means
suitable for the purpose may be adopted, and the resulting product or composition
may be applied to wire or to other forms of Electric conductors by any of the well
known methods now employed for coating and insulating, whether the wires or
other forms of Electric-conductors be braided or not.
The above proportions may be varied to make the material more suitable for
different kinds of Insulators and for the purposes for which insulation is required
to be adopted and there may be used in conjunction with the Asphaltum such
materials as steatite and also Oxide of Zinc or other pigment.
Having now particularly described and ascertained the nature of my Invention
and in what manner the same is to be performed I declare that what I claim is
The manufacture of compositions or materials to be employed for protecting and
insulating purposes consisting in the combination of Asphaltum or equivalent
pitchy matter, with drying oil or paraffin or ozokerit or Japan or vegetable wax or
both the oil and the wax substantially as herein before described, whether or not
other materials be employed in the composition as additions to the foregoing.
