page_text: I, FREDERICK TROTMAN of Albert House Albert Street London N.W..Refresh-
ment Contractor do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in machines for bottling aërated liquids
which improvements are more especially applicable for use in filling bottles provided
with stoppers of the class described in my former Letters Patent No 5264 dated
December 15th A.D 1880 that is to say bottles which are sealed by means of a
glass plug or stopper which is drawn (by means of a hook or similar device)
firmly and closely into contact with a ring of cork retained in a groove in the neck
of the bottle. The main objects of this invention are to provide means whereby
such stopper may be immediately drawn into close contact with the cork when the
bottle is filled so as to hermetically close the same, also means whereby an uniform
pressure of gas may be obtained in all the bottles filled and whereby the waste of
liquid during the filling operations is reduced to a minimum.
In carrying the said invention into practice I employ a standard or pedestal
provided with a table or support upon which the bottom of the bottle is placed and
which is attached to a treadle so that it may be raised and lowered to bring the
bottle into position to be filled and afterwards left free to be removed at the will
of the attendant in the usual way. Above this movable table or support I arrange
a fixed cup which is adapted to receive the neck of the bottle when the latter is
raised into the position to be filled, by the depression of the treadle. With the
interior of this cup communicates a pipe connected with the bottle charging
reservoir such pipe being provided with a suitable cut-off or valve to control the
admission of the liquid to the bottle as desired. With the interior of this cup a
pipe extending to a pressure guage also communicates so that when the inlet valve
from the reservoir is opened the pressure of the liquid and gas being admitted to
the bottle may be readily ascertained by the bottler and thus enable him if
desired to ensure the same pressure of gas in all the bottles filled. In addition,
I provide in such cup a passage which is connected with an escape pipe through
which the common air that is forced out of the bottle when being filled can pass so
that a series of movements of the treadle during the filling of a bottle (such as are
at present necessary in the ordinary method of bottling in order to allow such
...

air to escape) are rendered unnecessary. To ensure this result I provide within
the before mentioned passage a valve-seat against which a valve is normally forced
by a spring which may be adjusted as to its strength by means of a screw-nut so
as to suit the various pressures of gas employed in the bottling of different aërated
liquids. I also employ adjacent to the aforesaid cup a pivoted lever which carries
a rod of steel or other suitable material (preferably coated with silver or other
inoxidizable material) that is adapted to slide into and across the upper portion of
the interior of the cup when the lever is operated and through a loop or eye on the
book for drawing the plug or stopper firmly in contact with the ring of cork.
This lever is beld in, and returned to, its normal position by a suitable spring, in
which position the aforesaid rod does not project into the interior of the cup and
permits the neck of a bottle with the book passed through the hole in the stopper
to be freely forced upwards into the said cup by the depression of the treadle.
I provide a suitable shield to protect the bottler during the bottling operations.
The method of using my improved machine may be briefly described as follows:-
An empty bottle with the conical stopper supported loosely in the neck thereof by
the hook which is passed through the hole in such stopper and which is provided
with a loop that rests upon the top of the neck of the bottle is placed upon the
movable table and raised by the depression of the treadle so as to bring such loop
and the neck of the bottle firmly into position in the interior of the
cap which is
provided with a suitable slot or recess to receive the said loop. The inlet valve
from the charging reservoir is then opened and the liquid and gas pass freely into
the interior of the bottle. At the same time the pressure in the bottle is auto-
matically recorded by the pressure guage and when the desired pressure is reached
the aforesaid inlet valve is closed. At the same time also the pressure of liquid
and gas acts upon the aforesaid spring valve and moves the same from its seat so
that a passage is opened for the escape of the common air from the interior of the
bottle during the filling operation. When the bottle is thus filled and ready to be
closed the aforesaid pivoted lever is operated so as to force the rod into the interior
of the cup and through the loop of the hook. The treadle is then depressed so as
to leave the bottle free to be removed and by then giving the latter a downward
pull the stopper is drawn firmly into contact with the cork ring owing to the hook
being held by the rod passing through its loop. The lever is then released so as to
withdraw the rod from the loop and thus permit the bottle to be removed from the
machine. The hook is then removed from the hole in the stopper and the bottle
which has thus been filled is ready for use.

pipe extends to a pressure-guage i so that when the inlet valve h from the
charging apparatus is opened the pressure of the liquid and gas admitted to the
bottle may be readily ascertained by the bottler and he can therefore if desired
ensure the same pressure of gas in all the bottles filled. In addition I provide the
chamber with an escape pipe ; through which the common air that is forced
out of the bottle when being filled can pass so that a series of movements of the
treadle c during the filling of a bottle (such as are at present necessary in the
ordinary method of bottling in order to allow such air to escape) are rendered
unnecessary. To facilitate this result I provide the passage el with a valve seat
against which a valve k is normally forced by a spring which may be adjusted
as to its strength by means of a screw-nut m so as to suit the various pressures
gas employed in the bottling of different aörated liquids. I also employ adjacent
to the aforesaid cup a pivoted lever n which carries a rod n¹ of steel or other
Buitable material (preferably coated with silver or other inoxidizable material) that
is adapted to slide into and across the upper portion of the interior of the cup e
when the lever is operated and through a loop or eye on the hook o for drawing
the plug or stopper firmly in contact with the ring of cork in the bottle neck.
This lever n is held in, and returned to, its normal position on being released by
a spring n. When in its normal position the rod n' does not project into the
interior of the cup e and permits the neck of a bottle with the hook o passed
through the hole in the stopper to be freely forced upwards into the said cup by.
the depression of the treadle. If desired the cup e may be provided in its interior
with a slot to receive the loop of the hook o. p represents a shield to protect the
bottler during the bottling operations.
The method of using my improved machine may be briefly described as follows:-
An empty bottle with the stopper supported loosely in the neck thereof by the
hook o which is passed through the hole in such stopper and is provided with a
loop that rests upon the top of the neck of the bottle, is placed upon the movable
table 6 and raised by the depression of the treadle so as to bring the neck of the
bottle firmly into position in the interior of the cup as shown in Figure 2. The
inlet valve h from the charging reservoir is then opened and the liquid and gas
pass freely into the interior of the bottle. At the same time the pressure in the
bottle opens the valve k and permits such pressure to be automatically recorded
by the pressure-guage i and when the desired pressure is reached the aforesaid
inlet valve h is closed. As this valve k opens a passage is also left free for the
escape of the common air from the interior of the bottle during the filling operation.
When the bottle is thus filled and ready to be closed the pivoted lever n is operated
so as to force the rod n¹ into the interior of the cup e and through the loop of the
hook o.
The treadle is then released so as to leave the bottle free to be depressed
and by then giving the latter a downward pull the stopper is drawn firmly into
contact with the cork ring as the hook o is held by the rod n¹ passing through its
loop. The lever n is then released so as to withdraw the rod nr from the loop and
thus permit the bottle to be removed from the machine. The hook is then
removed from the hole in the stopper and the bottle which has been filled is ready
for use.
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
