Improvements in the Oxidation of Oils for Use in the Manufacture
of Paints or Varnishes or for other Purposes to which Oxidized
Oils are Applicable.
We ARTHUR BRIN of 59 Brompton Crescent in the County of Middlesex Engineer
and Chemist and LEON QUENTIN BRIN of 7 Rue Gavarni, Paris in the Republic of
France Engineer and Chemist, do hereby declare the nature of this Invention to be
as follows:-
The object of this Invention is to obtain Oxidized Oils for use in the manufacture of
paints or varnishes or for other uses in a rapid and efficient manner resulting in great
economy in the manufacture. Hitherto it has been customary to oxidize the oils by
means of metallic oxides or by exposure to atmospheric air. According to our
Invention the oils to be oxidized are submitted to the action of a current of oxygen
gas either under high pressure or not the said gas being passed into the oils by any
suitable means the oils being preferably kept agitated during the passage of oxygen
therethrough. Any suitable ordinary or elevated temperature may be employed
during the process.

page_text: We ARTHUR BRIN of 59 Brompton Crescent in the County of Middlesex Engineer
and Chemist and LEON QUENTIN BRIN of 7 Rue Gavarni Paris in the Republic of
France Engineer and Chemist 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 our Invention is to obtain oxidized oils for use in the manufacture of
paints or varnishes or for other uses in a rapid and efficient manner resulting in great
economy in the manufacture.
Hitherto it has been customary to oxidize the oils by means of metallic oxides or by
exposure to atmospheric air.
According to our Invention the oils to be oxidized are submitted to the action of a
current of oxygen gas either under high pressure or not, the said gas being passed
into the oils by any suitable means the oils being preferably kept agitated during the
passage of oxygen therethrough-Any suitable ordinary or elevated temperature may
be employed during the process.
The accompanying drawing represents apparatus suitable for the purpose of
performing our Invention-A is a vessel capable of being closed air tightly. It is
provided with an inlet pipe a for the admission of oxygen and with an outlet pipe a
for its escape and with a man hole b for cleaning or other purposes. It is surrounded
by a jacket C into the space between which and the chamber A steam or water or
other heating or cooling agent may be passed through the inlet and outlet passages c.
The interior of the vessel A is provided at bottom with a perforated coil D with which
the oxygen inlet a communicates so that the oxygen is delivered upwards in streams
through the oil. Inside the vessel A are fixed projecting blades or plates e-F is a
vertical shaft seated in the footstep bearing g at one end and at the other end passing
through a bearing to the outside of the vessel A and these provided with a pulley
by means of a strap passed over which rotatary motion may be given to the shaft which
has fixed to it projections or blades which as the shaft rotates pass between the
blades or plates eh is an opening closed by a plug by which opening the oil can be
admitted to the vessel A-In operating with the apparatus the oil to be oxidized is
put into the vessel A through the opening at h which is then closed and a current of
oxygen (which may or may not be under high pressure) is admitted by the pipe a and
steam is admitted into the jacket C unless the process is to be carried on at ordinary

page_text: temperatures-On the shaft F being rapidly rotated the oil is agitated and brought
into intimate contact with the oxygen whereby the oils are thoroughly oxidized-If
it be desired to bleach the oils as well as oxidize them a bleaching agent may be
introduced by the perforated pipe i. When the operation is completed the contents of
the vessel A are removed by the outlet valve d-It will be evident that the apparatus
may be arranged horizontally or at an angle instead of vertically as shewn.
Having now particularly described and ascertained the nature of our said Invention
and in what manner the same is to be performed we declare that what we claim is.
First. The oxidation of oils by treatment with oxygen gas substantially as
described.
Second. The manufacture of oxidized oils by submitting oils whilst agitated to the
action of a current of oxygen gas substantially as hereinbefore described with reference
to the accompanying drawings.
