My Invention refers to the employment of Resin whether dehydrated, bleached,.
purified or otherwise in combination with Castor oil Linseed oil or Cotton seed oil.
or other Drying oils whether oxidised or not and also of Paraffin or of Ozokerit
Japan or Vegetable wax one or more of these in comparatively small proportion
with Resin or Resins so as 'to render the insulating material less brittle and at the
same time 'to make it a more perfect insulator or protector of the Telegraphic, or
Telephonic wire, or other form of conductor.

The principal object of my Invention is to produce a cheap and efficient protec-
tion of wire or conductors employed either for Telegraphic Telephonic or for other
purposes and at the same time to produce a compound that can be applied wi
with:
great facility for the purposes herein before mentioned particularly such as those
which are required to be laid under ground for example in troughs or in tubes or
in other, receptacles.
I have found that about the following proportions will form a good compound
for insulating or protecting the wires or other articles employed for Telegraphic,
Telephonic or for other purposes, viz: about 95 Resin whether dehydrated or
not or either pufified or not 5 to 10 of oil to which other matters may be
added or not. Another combination of the materials may be made by employing
about 90 of Resin and about 5 "to about 10 of Paraffin or of Ozókerit about
1to about 2lb of either of the oils.
°
The oil I prefer to employ in forming the above combinations is Boiled Linseed
oil, whether oxidised 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.

Chemist do hereby declare the nature of my invention for "IMPROVEMENTS IN THE
COMPOSITION OF MATERIALS TO BE EMPLOYED IN PROTECTING AND INSULATING
WIRES AND FOR OTHER 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 refers to the employment of Resin whether dehydrated, bleached,
purified or otherwise in combination with Castor Oil, Linseed oil or Cotton seed
oil or other drying oils whether oxidised or not and also of paraffin or of Ozokerit,
Japan or vegetable wax one or more of these in comparatively small proportions
with Resin or Resins so as to render the insulating material less brittle and at the
same time to make it a more perfect insulator or protector of the telegraphic or
Telephonic wire or other form of conductor.
The principal object of my Invention is to produce a cheap and efficient protec-
tion of wire or conductors employed either for Telegraphic Telephonic or for other
purposes and at the same time to produce a compound that can be applied with
great facility for the purposes hereinbefore mentioned particularly such as those
which are required to be laid under ground for example in troughs or in tubes or
in other receptacles.
I have found that about the following proportions will form a good compound
for insulating or protecting the wires or other articles employed for Telegraphic
Telephonic or for other purposes viz: about 95 Resin whether dehydrated or not
and either purified or not and 5 to 10 of the drying oil to which other matters
may be added or not. Another combination of the materials may be made by
employing about 90 of Resin and about 5th to about 10th of Paraffin or of
to about 2 of either of the drying oils.
Ozokerit and about 1
The oil I prefer to employ in forming the above combinations is boiled Linseed
oil whether oxidised 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.
Any or all of 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 or 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,

page_text: Having now particularly described and ascertained the nature of my said
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 Resin with drying oil and with
or without Paraffin or Ozokerit or Japan or Vegetable wax substantially as herein-
before described whether or not other materials be employed in the composition as
additions to the foregoing.
