PROVISIONAL SPECIFICATION left by the said Charles Otto Heyl
at the Office of the Commissioners of Patents, with his Petition,
on the 19th October 1871.
I, CHARLES OTTO HEYL, of Berlin, in the Kingdom of Prussia,
5 Manufacturer, do hereby declare the nature of the said Invention for
"IMPROVED MEANS AND APPARATUS FOR SEPARATING OIL FROM THE BI-SULPHITE
USED IN ITS EXTRACTION, FOR REGAINING THE BI-SULPHITE, AND FOR PURIFYING
THE ATMOSPHERE," to be as follows:-

page_text: combines the functions of the two separate apparatuses described in the
Specification to my Letters Patent, No. 3010, A.D. 1862, and indicated
on the Drawing by the Nos. 2, 2, and 3. This improved apparatus
may be made partly of copper and iron, entirely of one or other of
those metals, or of any material which may be found suitable. The
space A is the steam jacket; a, distilling worm; b, steam entrance to
steam jacket; c, inlet for liquid to be distilled; d, steam outlet. The
distilled bi-sulphite passes away at the top by the outlets e, e, (the
apparatus shown has four outlets, but one or any number may be used
at pleasure,) and the perfectly purified oil is drawn off by a cock placed
at the bottom of the apparatus at f. 7 is a crank on the shaft k, which
extends across the apparatus from side to side, but is broken off on the
Drawing to prevent confusion with the worm a. This shaft carries the
bars i, which on the crank being turned give motion to the liquid, the
object of this motion being to maintain the same specific gravity in 1
every part of the liquid. k, guage to show height of liquid within
apparatus; ², inspection cocks.
Secondly. In improved means and apparatus for regaining the bi-
sulphite evolved into the air from the apparatus in which it is employed,
from the reservoirs, et cetera. For this purpose I make use of the long
drum shown in longitudinal sectional elevation at Fig. 2 and in cross
section at Fig. 3 of the accompanying Drawings. The paddles m being
set in motion by the rotating shaft n, oil purified in apparatus Fig. 1
or any purified oil introduced into the drum at o is kept in constant
agitation, always presenting fresh surfaces to scize upon the volatilized
bi-sulphite, which collected in a gasometer passes from thence into the
drum at p, the purified air escaping at q.
In the oil-extracting apparatus illustrated Fig. No. 1 of the Drawing
forming part of the Specification to my aforesaid Letters Patent,
No. 3010, A.D. 1862, the air still charged with bi-sulphite has been
allowed to escape through a hole in the cover.
I propose also to regain this bi-sulphite in the following manner :-I
close the said air outlet and cause the air to pass out through the same
opening as the extracted oil into the second similar extraction pan,

page_text: Thirdly. In a means of purifying the atmosphere surrounding the
extraction apparatuses. For this purpose I place an air pump beneath
the floor of the room, the effect of the working of which is that the air
containing traces of the bi-sulphite being heavier than pure air is
5 entirely drawn from the apartment, and by the use of an air condensing
and cooling apparatus of any kind I give to the bi-sulphite whatever
temperature may be most suitable for the working.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Charles Otto Heyl in the Great Seal Patent Office
on the 11th April 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
OTTO HEYL, of Berlin, in the Kingdom of Prussia, Manufacturer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Mer
Letters Patent, bearing date the Nineteenth day of October, in the year
of our Lord One thousand eight hundred and seventy-one, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Charles Otto Heyl, Her special licence
that I, the said Charles Otto Hey), my executors, administrators, and
assigns, or such others as I, the said Charles Otto Hoyl, my executors,
administrators, and assigns, should at any time agree with, and vo
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for “IMPRoved Means
and Apparatus FOR SEPARATING OIL FROM THE BI-SULPHITE USED IN ITS EXTRAC-
TION, FOR REGAINING THE BI-SULPHITE, AND FOR PURIFYING THE ATMOSPHERE,”
upon the condition (amongst others) that I, the said Charles Otto
Heyl, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and

page_text: be performed, to be particularly described and ascertained in and by the
following statement :-
My Invention consists,―
The
Firstly. In the combined oil distilling and purifying apparatus illus-
trated Fig. 1 of the accompanying Sheet of Drawing, which apparatus
combines the functions of the two separatus apparatuses described in the
Specification to my Letters Patent, No. 3010, A.D. 1862, and indicated
on the Drawing by thes Nos. 2", 2", and 3. This improved apparatus 1
may be made partly of copper and iron, entirely of one or other of those
metals, or of any material which may be found suitable. The space A
is the steam jacket; a, distilling worm; b, steam entrance to steam
jacket ; c, inlet for liquid to be distilled; d, steam outlet.
distilled bi-sulphite passes away at the top by the outlets e, e, (the ]
apparatus shown has four outlets, but one or any number may be used
at pleasure,) and the perfectly purified oil is drawn off by a cock placed
at the bottom of the apparatus at f. g is a crank on the shaft h, which
extends across the apparatus from side to side, but is broken off on the
This shaft carries the
Drawing to prevent confusion with the worm a.
bars i, which on the crank being turned give motion to the liquid, the
object of this motion being to maintain the same specific gravity in
every part of the liquid. k, guage to show height of liquid within
apparatus, inspection cocks.
Secondly. In improved means and apparatus for regaining the bi-
sulphite evolved into the air from the apparatus in which it is employed,
from the reservoirs, et cetera. For this purpose I make use of the long
drum shown in longitudinal sectional elevation at Fig. 2, and in cross
section at Figure 3 of the accompanying Drawings. The paddles m
being set in motion by the rotating shaft n, oil purified in apparatus
Fig. 1 or any purified oil introduced into the drum at o is kept in
constant agitation, always presenting fresh surfaces to seize upon the
volatilized bi-sulphite, which collected in a gasometer passes from
thence into the drum at p, the purified air escaping at q.
In the oil-extracting apparatus illustrated Fig. No. 1 of the Drawing
forming part of the Specification to my aforesaid Letters Patent,
No. 3010, A.D. 1862, the air still charged with bi-sulphite has been
allowed to escape through a hole in the cover.

page_text: I propose also to regain this bi-sulphite in the following manner :—I
close the said air outlet and cause the air to pass out through the same
opening as the extracted oil into the second similar extraction pan,
entering it at the bottom and escaping at the top perfectly free from
smell.
Thirdly. In a means of purifying the atmosphere surrounding the
extraction apparatuses. For this purpose I place an air pump beneath
the floor of the room, the object of the working of which is that the air
containing traces of the bi-sulphite being heavier than pure air is
entirely drawn from the apartment, and by the use of an air condensing
and cooling apparatus of any kind I give to the bi-sulphite whatever
temperature may be most suitable for the working.
Having now described and ascertained the nature of my said Inven-
tion, and in what manner the same is or may be performed, I would
3 have it understood that I do not confine myself to the precise details
herein set forth, as such may be varied while retaining the essential
features of my Invention, and that I claim as secured to me by the
herein-before in part recited Letters Patent,-
Firstly. The use of steam when employed in a single apparatus, both
for the separation of the oil and the bi-sulphite and for the purification
of the oil, substantially as hercin-before set forth.
Secondly. The use of oil in agitation, and of oleaginous seeds and
fatty matters generally, for the purpose of recovering from the atmo-
sphere the bi-sulphite which it may contain, substantially as hercin-before
set forth.
Thirdly. The use of an air-pump in combination with an air condensing
and cooling apparatus, substantially as and for the purposes herein-before
set forth.
T
it culinant T the maid Chanlos Otto Harl have lomounta
and cooling apparatus, substantially as and for the purposes herein-before
set forth.
In witness whereof, I, the said Charles Otte Hey!, have hereunto
set my hand and scal, this Eleventh day of April, in the year
of our Lord One thousand eight hundred and seventy-two.
