A New or Improved Combined Apparatus for Aerating Liquids,
Cooling, Fire Extinguishing, and Filtering.
I HERBERT SAMUEL ELWORTHY of Sujanpur, District of Gurdaspur, Punjab,
India, Analytical Chemist 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:-.
In accordance with this my invention, in a box or case made of any suitable
material I have two vessels preferably of cylindrical form. One vessel to be of
such a form and of such strength and material, preferably cylindrical and made
of steel, as is best fitted to contain highly compressed or liquified carbonic acid gas,
this cylinder is fitted with a cock and may have a reducing valve attached to
reduce the issuing gas to any required pressure. The other vessel may be made of
glass, silver, aluminum silver plated copper, enamelled iron or steel or any other
suitable material for containing water to be charged with carbonic acid gas from the
first vessel, this vessel is fitted with a cock and internally with a tube reaching
nearly to the bottom of the vessel, a flexible or other tube or pipe may be used to
connect the two vessels when charging the water cylinder. Either the same or
another tube may be used to connect the gas cylinders with the ordinary syphon or
seltzogene if desired.
In the accompanying sheet of drawings
Fig. 1 represents in elevation the vessels above described arranged in the box or
case aforesaid and
Fig. 2 is a plan of same.
A is the steel cylinder containing the liquified carbonic acid gas fitted with
reducing valve A', B the vessel containing the water to be charged with the
carbonic acid gas, C is the tube connecting the two vessels, D is the regulating
cock, and E the tube arranged internally in the vessel B and previously described
as reaching nearly to the bottom of the vessel and F is a tube connecting the
vessel B to the syphon or seltzogene.
Combined with the aforesaid vessels in the box or case G. I employ a particular
and peculiar device by which water or soda-water contained in a glass or other
vessel may be cooled by the expansion of the compressed or liquified carbonic acid
gas such as described in the Specification accompanying my application for Letters
Patent dated December 9th A.D. 1891 No. 21518.
The box or case G containing the compressed gas and soda or aerated water
vessels may also be made with separate compartments to contain ice or one or more
bottles of liquor, (L Fig. 2 representing a bottle so contained). A portable filter
may also be contained for the purpose of obtaining pure water at all times. If
preferred the gas cylinder or vessel may be separate from the rest of the apparatus
in order that a larger cylinder may be used if required.
For domestic use and for travellers and camp use these portable soda or aerated
water machines will be of great convenience and value, avoiding the heavy losses
incurred by breakages of bottles, and rendering aerated water available in places
where carriage is so high as to preclude their use at present. It will also render,
by the use of the cooler above described, a supply of icecold water or other beverage
available at any time.
By attaching a jet or sprinkling nozzle M, in dotted lines Fig. 1, to the vessel
containing the aerated or soda water, a small hut powerful and effective fire engine
is at once available and by its handiness may render effectual aid at the commence-
ment of a fire.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed 1 declare that what
I claim is:--
The combination of a compressed or liquified gas vessel and an aerated- or soda-
water vessel in an outside case or box, together with the necessary cocks, reducing
valve and connecting tubes constructed and operating as and for the purpose as
herein described and illustrated in the accompanying drawings.
Dated this 16th day of November 1891.
