Improvements in and in the Manufacture of a Preparation or
Substance Applicable as a Substitute for Indiarubber and for
Waterproofing or Dressing Cloths, Sheetings, and other Articles,

1. SEPTIMUS KENYON, of Warrington, in the County of Lancaster, Oil and Varnish
Manufacturer, do hereby declare the nature of this invention to be as follows :—
The object of the invention is primarily to provide a substitute for indiarubber, to
be applied to many of the purposes for which that article is now used, though the
improved preparation may also be used for, or applied to, a number of purposes, such
as waterproofing cloths-for the manufacture of oil skin, and other waterproof
clothing for the dressing of sheeting (with or without a pigment or colouring matter)
for lurry and van covers; and for other analagous purposes where a material insoluble
in water is required.
It consists essentially of a preparation of, or article prepared from, oxidised linseed
oil dissolved in any suitable solvent and in the method of dissolving or manufacturing
game.
In carrying out the invention 1 take oxidised linseed oil, such as the refuse skin
from boiled oil or oil specially oxidised for the purpose and add thereto a solvent
such as the distillate or foots produced in the manufacture of varnish from gums or
gum resins; pine oil or thick pine grease; resin oil; resin or other similar
substances. One or other of these solvents is placed in a pan and the oxidised oil
added thereto, and subsequently, by means of steam or otherwise, heated to a high
temperaturec, at which temperature it is kept until the two are thoroughly incorporated
together into a mass, more or less dense, according to the quantity of the solvent used.
The product may be made of any consistency according to the purpose for which it
is to be applied. When the oil is completely dissolved or thoroughly incorporated
with the solvent it is run out of the pan to cool and solidifies somewhat in the
process.
The product is afterwards soluble in oil, turpentine, bisulphide of carbon, and
mineral spirit or any of the ordinary solvents for indiarubber.

Improvements in and in the Manufacture of a Preparation or
Substance Applicable as a Substitute for Indiarubber and for
Waterproofing or Dressing Cloths, Sheetings, and other Articles,
also for other Purposes.
1, SEPTIMUS KENYON, of Warrington, in the County of Lancaster, Oil and Varnish
Manufacturer, 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 :-
The object of this invention primarily is to provide a substance which may be
mixed with or applied as a substitute for india-rubber for many of the purposes for
which that article is now used though it may also be applied alone or added to
materials at present in use to various other purposes such as the waterproofing of
cloths, for the manufacture of oil skins and similar waterproof clothing or covering
the dressing of sheeting (with or without the addition of a pigment or other colouring

page_text: matter) for lurry cart and van covers; the thickening of linseed oil (boiled or
unboiled) or as a substitute for thickened linseed oil and other purposes where a
soft plastic material soluble in naphtha and certain oils but insoluble in water is
required.
It consists essentially of a preparation of, or substance prepared from, oxidised
linseed oil such as the skins and refuse of boiled oil dissolved in any suitable solvent
and in the method of dissolving or manufacturing.same.
In carrying out the invention. I take oxidised linseed oil either the refuse skins
from boiled oil or oil specially oxidised for the purpose and mix therewith a liquid
in which it will dissolve or with which it will combine when heated. The
solvent material I prefer to use is the distillate or distilled fumes produced in the
manufacture of varnish from gums or gum resins though I also find that varnish
foots, pine oil, or thick pine grease, resin, resinous oil or a mixture of two or more of
these or other similar substances will also act as solvents when heated for the oxidised
(skins of) boiled oil.
1. place the varnish distillate or other solvent in a pan or still heated by steam or
otherwise and add thereto the skins of boiled oil, or oxidised oil and mix the two well
together, (or they may be mixed prior to being placed in the pan). The proportion
of the solvent to the oxidised oil will altogether depend on the consistency of the
product desired. To make the product of about the consistency of raw indiarubber
I use one part of the varnish distillate to three parts of the boiled oil skins but to
produce substance of a thick treacly consistence I use about equal parts of each.
The mixture in the pan is then heated to about the temperature of boiling oil say
350° to 450 F and maintained at that heat for a considerable time until all the hard
,or oxidised masses of the oil are dissolved in or thoroughly incorporated or combined
with the varnish distillate or other solvent used (say from 12 to 24 hours). The
duration of the operation will to a large extent depend on the relative proportions
of the oxidised oil and the solvent and also on the amount of the material under
operation. Where equal quantities of the oxidised skins of the oil and of the
varnish distillate are mixed together to the quantity of about ton the operation
will, I find, in a covered pan without pressure, he completed in about 12 hours.
When the oil is completely dissolved or thoroughly incorporated with the solvent
it is 'run out of the pan to cool and solidifies somewhat in cooling.
The product is soluble in or may be used with turpentine, bisulphide of carbon
and naphtha and mineral spirit or any of the ordinary solvents for indiarubber.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I'
claim is :-
1. A substance applicable as a substitute for indiarubber also for waterproofing
and for other purposes prepared from the skins of boiled oil or oxidised linseed
oil dissolved in varnish distillate or other solvent substantially as described.
2. The process of manufacturing or producing a solid or semisolid or viscous
soluble substance from the refuse skins of boiled oil, or oxidised linseed oil which
consists in mixing the skins or oil with varnish distillate, varnish foots, pine oil, resin
or resinous oils and boiling the mass at a high temperature in a suitable pan or
still until the two are thoroughly combined substantially as described.
