Britain and Ireland, bearing date at Westminster, the Eighteenth day of

from time to time and at all times during the term of years therein expressed,

Guernsey, Alderney, Sark, and Man, and also in all Her said Majesty's

page_text: description of the nature of my said Invention, and in what manner the same
is to be performed, by an instrument in writing under my hand and seal, to be
inrolled in Her said Majesty's High Court of Chancery within six calendar
months next and immediately after the date of the said in part recited Letters
Patent, as in and by the same, reference being thereunto had, will more fully
and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
John Lienau, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, are fully described and
ascertained in and by the following statement thereof, reference being had to
the Drawing hereunto annexed and to the figures and letters marked thereon
that is to say:--
In order to produce a superior oil for lubricating and burning purposes, I
have invented the following process:-I take such a quantity of the following
essential oils, or any of them, videlicet, oil of cummin, oil of aniseed, creosote,
oil of rosemary, and pour the same into the raw oil, either mineral, animal, or
vegetable, as will produce fermentation. After this has been done the oil is
passed through the filter apparatus in the following manner:-The bag G is
fastened in the interior of the vat A by means of the iron hoop J, and rests at
the bottom on the perforated cover B, the latter resting on the iron frame C.
The oil or liquid is then poured into the bag and the pumps D are set in
motion. Whilst these, creating a vacuum, draw out the oil or liquid from the
bottom of the vat the oil or liquid passes through the nozzles of the pumps and
A, wooden or metallic vat; B, wooden or metallic perforated cover; C, iron
frame on which the cover B rests; D, air-tight suction pumps; E, iron sup-
porters; F, iron handle; G, bag, woollen, cotton, or linen; H, valves through
which the air and refined liquid pass; J, iron hoop.
In witness whereof, I, the said John Lienau, have hereunto set my
band and seal, this Twelfth day of July, in the year of our Lord One
thousand eight hundred and fifty-one.
