I, EDWARD PHILLIPS of 84 Bishopsgate Street Within, in the City of London,
Merchant, do hereby declare the nature of this invention to be as follows:-
At
The object of this invention is to provide a means of distinguishing the various
qualities of petroleum oils, especially those employed for illuminating purposes.
the present time small consumers of petroleum oil have no ready means of ascertaining
for themselves whether the oil they buy is of the special brand or quality which it is
alleged by the oilman to be, as the petroleum is generally supplied to the consumers
in their own cans or bottles, from the oilman's tank, a brand or trade mark thus being
therefore of little or no use as a guarantee to the small consumer.
This invention consists in coloring or tinting each separate brand or quality of
petroleum with a distinguishing tint or color, by adding thereto a small quantity of a
coloring or dyeing material. The consumers are thereby enabled to ascertain at
a glance the quality of the petroleum supplied to them however small the quantity
may be.

page_text: I, EDWARD PHILLIPS, of 84 Bishopsgate Street within, in the City of London,
Merchant, 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 is to provide a simple means of distinguishing at sight
the various qualities of petroleum oils, especially those employed for illuminating
purposes. At the present time small consumers of petroleum oils have no ready
means of ascertaining for themselves whether the oil they buy is of the special brand.
or quality which it is alleged by the oilman to be, as the petroleum is generally
supplied to the consumers in their own cans or bottles from the oilman's tank; a
brand or trade mark being therefore of little or no use as a guarantee to the smaller
consumer.
This invention consists in colouring or tinting each separate brand or quality of
petroleum with a distinguishing tint or colour, by adding thereto a small quantity
of a colouring or dyeing material. The consumers are thereby enabled to ascertain
at a glance the quality of the petroleum supplied to them however small the quantity
may be.
I have found the aniline dyes suitable for this purpose especially those producing
scarlet and violet tints. Anchusine bark which gives a pink tint is also suitable.
Petroleum at ordinary temperatures is not a good solvent of dye stuffs, it is therefore
preferable to dissolve the dyeing or other colouring material, especially the aniline
dyes in a comparatively small quantity of the oil heated to a temperature of about
150 degrees Fahrenheit and then to add the mixture so prepared to the bulk of oil it
is desired to colour. The quantity of colouring matter to be used in proportion to a
given quantity of oil to be treated is of course dependent upon the tint or shade it is
desired to impart thereto. By this invention consumers are not only enabled to
ascertain at sight whether the oil supplied to them is of a definite quality, bui
dangerous admixtures of oil with benzoline and other similar spirits are detected by
altered appearance due to the reduction of the intensity of the tint which takes place
when untinted spirit is added to tinted oil and the possibility of benzoline or other
spirit being accidentally supplied in lieu of petroleum oil is rendered practically
impossible.
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 :-
Colouring or tinting petroleum oils by adding thereto colouring or dyeing material
as hereinbefore described, and for the purpose specified.
