A Process for Oxidising and Drying Vegetable Oils and Utilizing
the same for the Manufacture of Floor Cloth and like Products.
I, FREDERICK WALTON of No. 2 Eaton Place Brighton in the County of
Sussex, Manufacturer do hereby declare the nature of this invention to be as
follows:-
My invention relates to a rapid and inexpensive process for oxidising and drying
vegetable oils so as to get them into condition suitable for being made up with
gum and resins into compositions for manufacturing floor cloth, linoleum, lincrusta
and like products.
According to a method previously patented by me and now largely used, the
oil is exposed to aëration in thin films laid successively over largely extended
fabric surfaces. The oxidation and drying in this way occupy months, whereas the
process which I am about to describe may be carried out in a few hours. 1 charge
the oil to be treated, such for instance as boiled linseed oil, into a strong vessel
provided with hollow revolving agitators with perforated arms by which I force air
under a pressure which may be from 5 to 10 atmospheres through the oil. 1-heat
the oil to a temperature of about 100° F. which may be done by admitting hot
water or steam to a jacket of the vessel while a large volume of air is forced
through the oil and the agitators are rapidly worked. As the oil gradually solidifies,
the speed is reduced, and ultimately the oil is brought into a granular condition
freed from all greasiness.
Although I have mentioned air as being forced into the body of oil, oxygen or
ozone may be employed and turpentine vapour may be mingled with these or with
the air. The oil treated as above described tends to absorb oxygen very rapidly
and, if warm it may become ignited. It should therefore be cooled before being
discharged into the open air, and it may with advantage be passed between cold
rollers pressing it into cake. It can be compounded with resins and gums to form
cement for the manufacture of linoleum and like products. In compounding it with
these materials they should in the first place be fused, and then the oxidised oil
should be added to the molten mass the whole being agitated until the compounding
is completed.

A Process for Oxidising and Drying Vegetable Oils and Utilizing
the same for the Manufacture of Floor Cloth and like Products.
I, FREDERICK WALTON, of No. 4 Portugal Street, Lincolns Inn Fields, in
the County of London, Manufacturer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement :-
My invention relates to a rapid and inexpensive process for oxidising and drying
vegetable oils so as to get them into condition suitable for being made up with gun
and resins into compositions for manufacturing floor cloth, linoleum, lincrusta and
like products.
According to a method previously patented by me and now largely used, the oil
is exposed to aëration in thin films laid successively over largely extended fabric

page_text: surfaces. The oxidation and drying in this way occupy months, whereas the
process which I am about to describe may be carried out in a few hours. I charge
the oil to be treated, such for instance as boiled linseed oil, into a strong vessel
provided with revolving agitators, through a perforated bottom of which vessel I
force air under a pressure, which may be from 5 to 10 atmospheres, through
the oil.
The agitators may be made with hollow arms supplied with air under pressure
which can issue by numerous perforations from the arms into the body of the oil.
I heat the oil to a temperature of about 100° F., which may be done by admitting
hot water or steam to a jacket of the vessel while a large volume of air is forced
through the oil and the agitators are rapidly worked. As the oil gradually
solidifies, the speed is reduced, and ultimately the oil is brought into a granular
condition freed from all greasiness.
Although I have mentioned air as being forced into the body of oil, vapour of
turpentine or other oxidising body may be mingled with the air. The oil treated
as above described tends to absorb oxygen very rapidly and, if warm it may become
ignited. It should therefore be cooled before being discharged into the open air,
and it may with advantage be passed between cold rollers pressing it into cake.
It can be compounded with resins and gums to form cement for the manufacture
of linoleum and like products. In compounding it with these materials, they should
in the first place be fused, and then the oxidised oil should be added to the molten
mass, the whole being agitated until the compounding is completed.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The herein described process for oxidising and drying vegetable oils by forcing
air under pressure through the oils while they are warm and agitated.
