I, FREDERICK WALTER, of 47 Hassett Road, in the County of Middlesex,
Mechanical draughtsman, do hereby declare the nature of this invention to-be
as follows:
My invention relates to the storage and service of aërated beverages such as
lemonade, and it is designed to effect the same in such a manner, that they shall not
lose their sparkling properties, and that they can be served from a tap in manner
similar to that now employed for malt liquors.
After the aëration of the liquid I do not bottle same, but store it in suitable
casks or vessels. These casks or vessels are fitted with a suitable joint for the
attachment of an air pump or a pipe leading thereto. Thus when the beverage is
delivered to the retailer, he may place the cask or vessel in his cellar, and have a
pipe leading up to a suitable tap at the bar, where also is a suitable air pump.
On withdrawal of any of the contents of the barrel for the service of the public,
a stroke or two of the air pump by the attendant will keep up the necessary
pressure in the cask or vessel to prevent de-aëration of the contents, and, at the
same time to force the liquid up to the tap in the bar.

and Service of Aerated Beverages.
I, FREDERICK WALTER, of 47 Hassett Road, in the County of Middlesex,
Mechanical draughtsman, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :—
My invention relates to the storage and service of aërated beverages, such as
lemonade, and it is designed to effect the same in such a manner, that they shall
not lose their sparkling properties, and that they can be served from a tap in
manner similar to that now employed for malt liquors to which it is also
applicable.
After the aëration of the liquid, I do not necessarily bottle the same, but store
it in suitable casks or vessels. These casks or vessels are fitted with a suitable
joint for the attachment of an air pump or a pipe leading thereto. Thus, when
the beverage is delivered to the retailer, he may place the cask or vessel in his
cellar, and have a pipe leading up to a suitable tap at the bar, where also is a
suitable air pump. On withdrawal of any of the contents of the barrel for the
service of the public, a stroke or two of the air pump by the attendant will keep
up the necessary pressure in the cask or vessel to prevent de-aëration of the
contents, and at the same time, to force the liquid up to the tap at the bar.
In order that my invention may be the better understood, I now proceed to
describe the same in relation to the drawing hereunto annexed, which is a sectional
elevation of my device complete.
The form of cask or vessel I preferably employ is that shown in the drawing,
where A is a wooden cask contained in a metallic outer and air tight cask B, so
that any escape of gas from A will only enter the space between A and B, and the
pressure will soon become in equilibrium and no risk of leakage will occur. Though
I prefer this form, others would be equally suitable, and formed of earthenware,
enamelled metal, glass, or other material. This cask or vessel is fitted with a
suitable joint C for the attachment of the tubes employed in my device. This
joint is formed with two passages, one for the attachment of each tube. D is a
tube leading to the air pump E, the piston rod of which is carried up to the bar
where the service of the liquor is effected, and may be operated by a suitable
bandle F. This tube is preferably carried to the bottom of the cask so that when
aëration is effected the liquor may at the same time be agitated. GG are the
supply tubes leading from the cask up to the service tap H. This service tap H
is fitted with a spring pressed valve K against the pressure in the cask or vessel.
The strength of this spring is so regulated with regard to the pressure in the cask,
that when this has fallen below a certain point the liquid will not flow, until the
pressure is restored by a few strokes of the air pump. The tubes are preferably of
glass and fitted to the joints by boiler gauge unions. The liquid is thus brought
into very little contact with metal.

page_text: In place of forcing air into the vessel, I may force carbonic acid or any other
suitable gas by means of my air pump.
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
1st In an improved apparatus for the storage and service of aërated beverages,
the combination with a containing cask of a suitable air pump and tubes and
supply pipe and cock with pressure valve, substantially as and for the purposes
specified.
2nd The method of serving aërated beverages by means of their own pressure
kept up by means of a force pump, substantially as and for the purposes specified.
Dated this 92nd day of April 1886.
