Goswell Road, in the County of Middlesex, Commercial Traveller,. for:
PROVISIONAL SPECIFICATION left by the said Lippmann Jacob Levisohn
at the Office of the Commissioners of Patents, with his Petition, on the
23rd August 1865.
I, LIPPMANN JACOB LEVISOHN, of Powell Street West, Goswell Road, in
the County of Middlesex, Commercial Traveller, do hereby declare the
nature of the said Invention for "AN IMPROVEMENT IN SYPHONS," to be as
follows:-
The object of my Invention is the drawing-off of liquids in large or small
quantities from bottles, jars, casks, and other receptacles without disturbing
the liquid, and at the same time without the admission of more air than
is necessary to allow of the outflow.
My improvement consists in fitting a cork, stopper, or bung on the lower
leg of a syphon tube, and in carrying an air tube or passage through the cork
or stopper, the admission of air into which is regulated by a cock, either that
on the longer leg of the syphon which regulates the outflow of the liquid or
by a separate cock. The size of the stopper must be such as to fit the mouth'
of the bottle or entrance into the vessel to which the syphon is to be applied.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, LIPPMANN
JACOB LEVISOHN, of Powell Street West, Goswell Road, in the County of
Middlesex, Commercial Traveller, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-third day of August, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Lippmann Jacob Levisohn, Her special licence that I, the said
Lippmann Jacob Levisohn, my executors, administrators, and assigns, or such
others as I, the said Lippmann Jacob Levisohn, my executors, administrators,
and assigns, should at any time agree with, and no 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 "AN IMPROVEMENT IN SYPHONS," upon the condition (amongst
others) that I, the said Lippmann Jacob Levisohn, my executors or adminis-
trators, 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 immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Lippmann Jacob Levisohn, do hereby
declare the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement thereof, reference being had to the Drawings hereunto
annexed, that is to say:-
The object of my Invention is the drawing-off of liquids in large or small
quantities from bottles, jars, casks, and other receptacles without disturbing
the liquid, and at the same time without the admission of more air than is
necessary to allow of the outflow.
My improvement consists in fitting a cork, stopper, or bung on the shorter
leg of a syphon tube, and in carrying an air tube or forming an air passage.
through the cork or stopper, the admission of air into which is regulated by
a cock, either that on the longer leg of the syphon which regulates the outflow
of the liquid or by a separate cock. The size of the stopper must be such

page_text: as to fit the mouth of the bottle or entrance into the vessel to which the
syphon is to be applied.
Figure 1 of the accompanying Drawings is a section of a syphon con-
structed according to my Invention. A is the shorter and B the longer
syphon leg; C is a stopper on the leg A, the size of which is such as to fit-
the mouth of the bottle or entrance into the vessel to which the syphon is
to be applied; D is an air tube or passage carried through the stopper C;
this tube extends round the bend of the syphon and down the longer leg,
and terminates in a passage formed through the cock E, which regulates'
the outflow of the liquid; F is another tube by which the air is withdrawn'
from the syphon when required.
. Figure 2 shows separate views of the plug of the cock E, showing the
different passages formed in it. a is the passage through which the liquid
flows from the syphon; 6 is a channel which when brought opposite the tube
F communicates between this tube and the leg B of the syphon; c is a
passage parallel to the passage a and forming a communication between the
tube D and the outer air when the cock is open; d is another passage which
comes opposite the tube D when the channel 6 is opposite the tube F. The
action of this syphon is as follows:-Turn the plug of the cock E a quarter
round, whereby the channel 6 is brought opposite the tube F and the leg B;
this movement opens the air passage d, but the liquid passage a remains
closed; exhaust the air from the syphon by means of suction applied to the
tube F, and the liquid in the bottle or vessel will enter the shorter leg A,
being replaced by air admitted through the air passage d and tube D; then
turn the cock another quarter round, whereby the tube F and the air passage
d are closed, and the liquid passage a and the other air passage c opened; the
liquid will then flow in a continuous stream through the syphon until the
liquid level in the bottle or vessel falls below the entrance to the leg A, being
proportionately replaced by air admitted through the air passage c and
tube D.
Figure 3 represents a modified form of my syphon. The exhausting tube
F is dispensed with, and instead thereof I make the longer leg B of the
syphon of two tubes, one of which slides outside the other similar to the
tubes of a telescope. By drawing down the outer tube (as represented in
dotted lines) after the shorter leg of the syphon has been inserted in the
bottle or other vessel a vacuum is formed in the syphon.
does not extend to the cock E, but has a separate cock G;
cock E has only one passage, videlicet the passage a, for the outflow of the
liquid.
The air tube D
in this case the

vessel I sometimes form this leg of two tubes, as shown in Figure 3, one.
of which is free to slide within the other. By drawing out or pushing in the
inner tube before the leg A is inserted in the bottle the length of this leg is
regulated as required.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim as my improve-
ment in syphons, fitting a cork, stopper, or bung on the shorter leg of the
syphon tube, and carrying an air tube, or forming an air passage through the
cork, stopper, or bung, substantially in the manner and for the purpose herein-
before described and represented in the accompanying Drawings.
In witness whereof, I, the, said Lippmann Jacob Levisohn, have
hereunto set my hand and seal, this Twenty-third day of February
One thousand eight hundred and sixty-six.
L. J. LEVISOHN. (L.S.)
