I IVAN LEVINSTEIN, of .21 Minshull Street Manchester in the County of
Lancaster, Chemist, do hereby declare the nature of the said invention for
IMPROVEMENTS IN APPARATUS FOR CHARGING BEER OR OTHER LIQUIDS WITH
CARBONIC ACID OR OTHER GASES AND DISCHARGING THE LIQUID FROM ITS
CONTAINING VESSEL," to be as follows:-
My improved apparatus and arrangements is intended more especially for
keeping fresh and brisk and reviving Lager and other beer, and discharging or
drawing it from the barrel or vessel in some cases some distance above the level of
the vessel which contains it, though also applicable for other purposes, where gases
are to be charged into liquids and forced or discharged from the barrel or cistern
in which they are stored.
My invention consists of a cylinder provided with a cone at one end having
a screw thread on its exterior so as to be screwed into the bung hole of the barrel
or vessel-The other end of the cylinder has a stuffing box through which a tube
can slide, and it has also a branch provided with a tap.
The tube or pipe passing through the stuffing box is capable of being slided in
and out of the cylinder and there is an annular space between the interior of the
latter and the exterior of the sliding tube so that gas can pass from the branch on
the cylinder through the annular space to the upper surface of the liquid in the
vessel.
Within the sliding tube there is another which I will term the interior tube,
made by preference of glass, and this interior tube forms a junction with the outer
end of the sliding tube above a branch from it provided with a tap.
The interior tube is joined up to a tube which has also a tap upon it.
The branch pipe from the cylinder has two branches, one of which is connected
with the interior tube by flexible rubber or other tubing, and the other branch is
connected with any suitable source, supply or generator of carbonic acid or other
gas which may be used.
Instead of using rubber tubing the branch of the interior pipe may be connected
with the branch supplying gas by sliding therein through a stuffing box, or the

page_text: two pipes may be connected by swivel jointed pipes. When the apparatus is to
be used for charging beer with carbonic acid gas and discharging the liquid from
the barrel the end sliding pipe is first drawn within the cylinder the cone end of
which forces the cork or bung into the barrel and is then screwed therein, the
sliding pipe is then forced down until its end comes against the bottom of the
barrel.
When the sedimont (which all beer contains more or less) has been allowed to
settle to the bottom of the barrel, the tap on the cylinder may be turned to admit
the carbonic acid gas to the upper surface of the liquid, when that part containing
the sediment will be forced out by its pressure up the annular space left between
the interior tube and the sliding. tube,, and will pass out at the tap upon it, when
open, and when the sediment is thus drawn off the tap on the cylinder is shut and
that on the pipe joined with the interior pipe is opened which conducts the gas
down the interior tube to the bottom of the barrel where it mixes with and is
partly absorbed by the beer or liquid, and its pressure, forces the liquid up the
annular space as before explained to the tap on the sliding tube where it is drawn
as required.
When beer or liquid is kept in vessels in a cellar or lower room and is to be
delivered and drawn in an upper room, an india rubber or other pipe connection is
made with the branch for the tap of the sliding pipe and also with a pipe leading
*to a tap in the room where the beer is to be drawn and the pressure of the gas in
the barrel or vessel will force the liquid to the withdrawing tap.
A modification of my invention consists in making the interior tube the outlet
for liquid and the annular space between the interior of the sliding pipe and the
interior tube the inlet for gas, and in making the cylinder with a two way tap and
a passage. to an annular space round the sliding tube, with a packing arrangement
above and below such annular space, from which the gas can pass through a hole or
holes in the side. of the sliding pipe to the said annular space between it and the
'interior tube, there is also a passage in the cylinder to convey the gas, when
required from the two way tap below the inner packing arrangement to the annular
space between the cylinder and sliding tube-In some cases with the last described
modification the interior pipe is or may be the passage for gas, and the annular
space between it and the sliding tube that for the liquid. This last described
modification with a two way tap is or may be used same as the first described
modification the two way tap being first turned to admit gas at the higher part or
above the surface of the liquid, and then shut when the sediment is removed, and
turned to admit gas to pass down the sliding tube, when the liquid is to be charged
with gas and discharged from its containing vessel.

Liquid from its Containing Vessel.
I IVAN LEVINSTEIN of 21 Minshull Street Manchester, in the County of
Lancaster, Chemist, do hereby declare the nature of said invention and in what
manner the same is to be performed, to be particularly described and' ascertained
in and by the following statement :-
My improved apparatus and arrangements is intended more especially for
keeping, fresh and brisk and reviving Lager and other beer and discharging or
drawing it from the barrel or vessel, in some cases some distance above the level of
the vessel which contains it, though also applicable for other purposes, where gases
are to be charged into liquids and forced or discharged from the barrel or cistern in
which they are stored.
My invention consists of a cylinder provided with a cone at one end having
a screw thread on its exterior so as to be screwed into the bung hole of the barrel
or vessel. The other end of the cylinder has a stuffing box, through which a tube
can slide, and it has also a branch provided with a tap.
The tube or pipe passing through the stuffing box is capable of being slided in
and out of the cylinder, and there is an annular space between the interior of the
latter and the exterior of the sliding tube so that gas can pass from the branch on
the cylinder through the annular space to the upper surface of the liquid in the
vessel:
Within the sliding tube, there is another which I will term the interior tube;
made by preference of glass, and this interior tube forms a junction with the outer
end of the sliding tube upon a branch from it provided with a tap.
The interior tube is joined up to a tube which has also a tap upon it.
The branch pipe from the cylinder has two branches, one of which is connected
with the interior tube by flexible rubber or other tubing, and the other branch is
connected with any suitable source, supply, or generator of carbonic acid or other
gas which may be used.
Instead of using rubber tubing the branch of the interior pipe, may be connected
with the branch supplying gas by sliding therein, through a stuffing box, or the
two pipes may be connected by swivel jointed pipes. When the apparatus is to be
used for charging beer with carbonic acid gas, and discharging the liquid from the
barrel the end sliding pipe is first drawn within the cylinder, the cone end of
which forces the cork or bung into the barrel and is then screwed therein, the
sliding pipe is then forced down until its end comes against the bottom of the
barrel.
When the sediment (which all beer contains, more or less) has been allowed to
settle to the bottom of the barrel, the tap on the cylinder may be turned to admit
the carbonic acid gas to the upper surface of the liquid, when that part con-
taining the sediment, will be forced out by its pressure, up the annular space left
between 'the 'interior tube and' the sliding tube, and will pass out at the tap upon

page_text: it, when open, and when the sediment is thus drawn off the tap on the cylinder is
shut and that on the pipe joined with the interior pipe is opened which conducts
the gas down the interior tube to the bottom of the barrel where it mixes with
and is partly absorbed by the beer or liquid, and its pressure, forces the liquid up
the annular space as before explained to the tap on the sliding tube where it is
drawn as required.
When beer or liquid is kept in vessels in a cellar or lower room and is to be
delivered and drawn in an upper room, an india rubber or other pipe connection is
made with the branch for the tap of the sliding pipe and also with a pipe leading
to a tap in the room where the beer is to be drawn and the pressure of the gas in
the barrel or vessel will force the liquid to the withdrawing tap.
A modification of my invention consists in making the interior tube the outlet
for liquid and the annular space between the interior of the sliding pipe and the
interior tube the inlet for gas, and in making the cylinder, with a two way tap
and a passage to an annular space round the sliding tube with a packing arrange-
ment above and below such annular space, from which the gas can pass through a
hole or holes in the side of the sliding pipe to the said annular space between it
and the interior tube, there is also a passage in the cylinder to convey the gas,
when required, from the two way tap below the inner packing arrangement, to the
annular space between the cylinder and sliding tube-In some cases with the last
described modification the interior pipe is or may be the passage for gas, and the
annular space between it and the sliding tube, that for the liquid.-This last
described modification with a two way tap is or may be used same as the first
described modification the two way tap being first turned to admit gas at the
higher part or above the surface of the liquid, and then shut when the sediment
is removed, and turned to admit gas to pass down the sliding tube, when the liquid
is to be charged with gas and discharged from its containing vessel.
Fig. 1 is an elevation of an apparatus according to one modification of. my
invention.
a is a cylinder, with a screwed cone upon it for screwing into the barrel. b is a
tube within the cylinder a and in which the tube b can slide passing through
a gland packing or stuffing box arrangement in the cylinder a at a³.
There is an annular space between the interior of the cylinder a and the exterior
of the tube b so that gas passing to the cylinder a at the branch a' can travel down
the annular space to act upon the surface of the liquid in the barrel or vessel.
The branch a¹ has a single way or a two way tap a² so that communications
may be opened with or shut off from the two branches ax and a-The branch a
has a coupling a to which one end of an india rubber or other tube is attached
the other end of which is in communication with the source of supply of gas under
pressure.
The other branch a* has also a coupling a7 to which one end of an india rubber
tube 62 is attached the other end being attached to a coupling branch 6³ with
which the india rubber tube is connected.
This india rubber tube 62 allows the sliding tube b to be moved in and out (to
bring the lower end of the tube b to the bottom of the barrel) while keeping up
the connection with the gas supply.
The branch b³ has or may have a tap b' if desired, and its bore is in communi-
cation with the pipe c in the interior of the tube b there being an annular space
between the two pipes or tubes which forms a junction with the branch b³ having a
tap 6 upon it-This branch when desired may have a pipe connected with it to
convey and deliver the beer or liquid at the place required.
It has been stated that the tap a² has or may have two ways so that the gas can
be directed so as to pass to the cylinder a and be cut off from the pipe 62 or vice
versa; it may be directed so as to pass to the pipe 63 and be out off from the
cylinder a and when a two way tap a² is used the tap b may be dispensed with,
but when a single way tap is used the tap 64 is required as shown in fig. 1.
The manner of using the apparatus is as hereinbefore described.

page_text: Fig. 2 is a longitudinal section and fig. 3 is a cross section on the line x-x
fig. 2 of a modification of my invention.
a is a cylinder with a screwed cone a¹ is a branch to be connected with the gas
supply under pressure, a² is a two way tap to open or close communication with the
interior of the cylinder a or with the passage a leading to a passage a³; b is a
pipe which can slide in the cylinder a, its upper end is screwed into a part bb, and
in the interior of the pipe b there is another pipe c which is also screwed into the
part 65, the bore of the pipe c communicating with the bore of the part 6 and the
tap 66 formed in it-There is an annular space between the pipes c and b and one
also between the latter and the interior bore of the cylinder a.
A length of the cylinder a is bored out to form a gland packing at both ends.
There is an hydraulic packing ring d2 with a metal ring ³ within it, then a
washer d, and another hydraulic packing ring do then a tube d, another hydraulic
packing ring do, and a screw cap a³-Any other arrangement of packing or stuffing
box may be substituted.
There are holes d' in the tube d and holes b¹ in the tube b so that gas from the
tap a can pass to the annular space between the two tubes b and c.
The packing rings d² and d³ prevent the gas round the tube d from getting to
the annular space between the tube b and interior of the cylinder a below the
passage.a-The space in the cylinder a the length of the tube is to allow for
various sizes of barrels, so that the inner end of the tube b may be adjusted to the
bottom of the barrel so long as the holes b¹, keep within the space between the
packing rings do and d³.
When gas is admitted by the tap a² it enters by the passage at and fills the
vessel above the level of the liquid and forces it up the interior tube c, or it is
Inade by the tap a² to pass through the holes d', b, into the annular space between
the tubes b and c to pass out at the bottom of the tube b, to mix with and aerate
the beer or liquid.
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
.
The combination and arrangement of apparatus for charging beer. or other
liquids with carbonic acid or other gases and for discharging such liquid from its
combining vessel substantially as hereinbefore described and illustrated by the
drawings.
