Improved Apparatus for Cooling Liquids.
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 :-
My invention relates to improvements in cooling apparatus and has for its object
to provide a simple and portable refrigerator whereby aerated or other liquid
contained in a glass or other vessel may be readily cooled. My improved cooling
apparatus is intended for use in connection with a bottle or other vessel containing
compressed carbonic acid or other gas and is more particularly applicable to the
aerated water machine described in the Specification accompanying my application
for Letters Patent No. 19815 bearing date the 16th of November, 1891.
This apparatus consists of a closed vessel containing a central vertical pipe
having a nozzle at its lower end, while its upper end is connected by a pipe and
screw joints to the outlet of a bottle or flask containing preferably liquid carbonic
acid gas. A pipe is coiled around this vessel near the bottom of which it enters
the lower end of the same.
In the case of small quantities required to be cooled, I may place the cooling
apparatus directly in the liquid to be cooled, and in the case of larger quantities
the cooling apparatus may be placed in a receptacle containing brine, spirits of
wine, glycerine, or other suitable refrigerating liquid and partially immersed in an
outer tank in which is placed the liquid required to be cooled.
In the accompanying drawings,
Figure 1 is a sectional elevation of my improved refrigerator, and Figure 2 is a
plan of the same.
In the centre of a box or tank B, I place a receptacle C containing brine, spirits,
glycerine, or other refrigerating medium and in this receptacle I place my improved
cooling apparatus. The tank B is furnished with an extension B having a circular
recess wherein the bottle A containing the compressed gas may be conveniently
supported. The outlet e of this flask of compressed gas is connected by means of
a pipe a of metal or other suitable material to the vertical pipe e arranged in the
centre of the vessel D of the cooling apparatus proper, and furnished with a
nozzle d at its lower end. The lower extremity of the pipe e enters the vessel D
around which it is coiled as shewn, its upper end being open at the top to allow the
gas to escape. The tank B is partly filled with the liquid required to be cooled.
The connections of the pipe a with the cooling apparatus and the bottle A are made
by means of the screw joints and 6 respectively. When the valve of the bottle A
is opened the gas passes through the pipe a and the pipe c into the vessel D, where
it expands producing intense cold, the vessel D being closed at the top compels the
said gas to travel through the coiled pipe e' on its way to the atmosphere, removing
heat from the liquid as it passes through.
Having thus 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 improved cooling apparatus, arranged constructed and operating substan-
tially as herein described and for the purpose set forth.
Dated this 9th day of December 1891.
