ALFRED JACOBS Engineer of Camberwell New Road and ISAAC JACOBS Merchant
of Newington Causeway both in the County of Surrey. "IMPROVEMENTS IN
BOTTLES FOR CONTAINING AERATED LIQUORS OR OTHER FLUIDS."
This Invention has for its object improvements in bottles for containing aerated
liquors or other fluids.
Our improved bottle may be of glass or earthenware; it has a neck in which
there is a side aperture or spout and also a direct passage.
Within the direct passage a screw-thread is moulded or formed and this receives
a corresponding screw. The screw which may be of wood or metal carries at its
inner end a ball of vulcanised india rubber which serves as a valve. The ball is
attached in any convenient way to the inner end of the screw.
There is a h-ad
Two seats are
on the exterior extremity of the screw by which it can be turned.
formed in the bottle for the ball valve an upper or inner seat and a lower or outer
seat.
When the ball is against the upper seat the bottle is open and the contents may
be poured out. In this position also the bottle may be charged through the spout
and the ball resting against the upper seat prevents any escape of gas during the
operation.
In the process of bottling when the bottle has been filled in this way the screw
is rapidly turned and screwed inwards which brings the ball against the inner seat

from the cavity of the bottle to the spout. The aerated liquid is thus enclosed in
the bottle where it will remain without loss of the gas with which it has been
charged until required for use. To draw it off a turn given to the screw relieves
the pressure and allows the liquor to be poured quietly into a glass.
It is obvious that if the whole contents of the bottle is not required for use at
one time that the ball valve can be closed down again against the inner seat when
the quantity required has been drawn off.
Although particularly suited for aerated liquors our improved bottle may also
be employed to hold other fluids.

This Invention has for its object improvements in bottles for containing aerated

Our improved bottle may be of glass or earthenware; it has a neck in which
there is a side aperture or spout and also a direct passage.
Within the direct passage a screw thread is moulded or formed and this receives
a corresponding screw. The screw which may be of wood or metal carries at its

on the exterior extremity of the screw by which it can be turned. Two seats are
formed in the bottle for the ball valve an upper or inner seat and a lower or outer
seat. When the ball is against the upper seat the bottle is open and the contents
may be poured out. In this position also the bottle may be charged through the
spout and the ball resting against the upper seat prevents any escape of gas, during
the operation.
In the process of bottling when the bottle has been filled in this way, the screw
is rapidly turned and screwed inwards which brings the ball against the inner
seat and pressing it upon the seat forms a gas tight joint thereby closing the
passage from the cavity of the bottle to the spout. The aerated liquid is thus
enclosed in the bottle where it will remain without loss of the gas with which it
has been charged until required for use. To draw it off a turn given to the screw
relieves the pressure and allows the liquor to be poured quietly into a glass.
It is obvious if the whole contents of the bottle is not required for use at one
time that the ball valve can be closed down again against the inner seat when the
quantity required has been drawn off.
Although particularly suited for aerated liquors are improved bottle may also
be employed to hold other fluids.
In order that our said Invention may be most fully understood and readily
carried into effect we will proceed to describe the Drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a vertical section of a glass bottle constructed according to our
Invention and adapted to contain aerated liquid.
a is a direct passage in the neck within it a screw thread is moulded b. is a side
passage in the neck, and cl. c. are valve seats. d. is a screw of wood or other
material, it has a head d. by which it may be conveniently turned. e is a ball
valve of vulcanized india rubber, carried by the screw d, the ball is perforated and
a stem at the end of the screw passes through it; at the end of the stem there
is a taper enlargement to retain the ball valve.
Bottles may be made according to our Invention in any of the materials in
which bottles are usually made.
Figure 2 shews a modification in which the neck with the valvular arrangement
is made separately from the body of the bottle, made in metal or other material
and can be used on any ordinary bottle. This portion may be made in metal, it is

page_text: taper at the lower end and armed with a ring of cork. Upon the body of the
bottle there is a mouth of like form adapted to receive the part shewn in the
Figure.
Having thus described the nature of our said Invention and the manner of
performing the same we would have it understood that we claim our improve-
ments in bottles for containing aerated liquors or other fluids substantially as
described.
In witness whereof I the said Alfred Jacobs have hereunto set my hand and
seal this Sixth day of July in the year of our Lord One thousand eight
hundred and eighty two.
