PROVISIONAL SPECIFICATION.
An Improved Apparatus for Distilling Water and other Liquids.
WILLIAM THORNTON COTTON of No. 5 Cancell Road, Brixton London S.W.
Mechanical Engineer and EDWARD LEWIS GARRETT No. 1 Milk Street
Buildings, Cheapside in the City of London Merchant do hereby declare the nature
of this invention to be as follows:-
This invention has for its object the distilling of water and other liquids, by
means of an improved evaporator, heated by steam, fire, or gas, and the vapour is
afterwards condensed in a surface condenser, by the cool water or other liquid
supplied thereby producing pure water or other liquid, free from all mineral,
organic or other impurities.
We accomplish this by arranging a number of tubes within a vertical chamber,
containing the water or other liquid to be evaporated.
A fire, gas jet or steam from steam boiler admitted to the evaporating tubes
whereby the temperature of the water or other liquid surrounding the tubes, is
raised above 212° Fahrenheit and the vapour thus generated is conducted into
an adjoining chamber and there condensed by another series of tubes surrounded
by cool feed water or other liquid and afterwards flows away from the condensing
chainber as pure distilled water or other liquid.
The water or other liquid supplied in this chamber and partially heated by
condensing the vapour, is then conducted as required, into the evaporating chamber
by an automatic float and valves, to regulate the supply and allow sufficient
space for the vapour, above the water or other liquid surrounding the evaporating
tubes.
A water gauge is attached to the evaporating chamber to indicate the proper
quantity of water or other liquid to be allowed therein, and the supply from the
condensing chamber, being constant is regulated by the automatic float & valves
therein.
The exit tube from the condensing chamber is without cock or valve, in order
to allow the vapour as it is condensed to flow away freely and to keep the pressure
therein nominal.

COMPLETE SPECIFICATION.
An Improved Apparatus for Distilling Water and other Liquids.
We, WILLIAM THORNTON COTTON, of 5 Cancell Road, Brixton, London, S. W.
Mechanical Engineer, and EDWARD LEWIS GARRETT formerly of 1 Milk Street
Buildings, Cheapside, in the City of London, but now of "Featherstone,"
Wallington, in the County of Surrey, Merchant, 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 :-
This invention has for its object the making of a compact and effective apparatus
for the distilling of water, and other liquids, the apparatus consisting of an
evaporator heated by steam, or by gas, or other fuel, and a surface condenser in
which the liquid evaporated is condensed by the cool water or other liquid supplied,
the result being the production of practically pure distilled water, free from mineral
n.

page_text: organic or other impurities, or a practically pure distillate of whatever liquid
may be submitted to the action of the said apparatus.
In order that the invention may be easily understood a drawing is attached
hereto and represents generally a vertical section of the apparatus to be heated
by gas, the tubes, pipes, ball cock, ball, and gas burner being in elevation.
For the purpose of carrying out the invention we make two circular, square,
or other suitably shaped vessels A and B, and divide each of them by the
respective plates C and D so as to constitute chambers E and F and G and H.
From each of the plates C and D are suspended a number of tubes open at top but
closed at the bottom. Between the two vessels A and B, or arranged in any other
convenient manner is a cistern I having a water supply pipe J terminating in a ball
valve and ball at its upper end. From the bottom of the cistern I there is a
pipe K which leads to the upper chamber E of vessel A, and from the chamber E
there is a pipe L that communicates with the chamber G of the vessel B. At the
upper part of G there is also a pipe M that conveys the steam generated in G to
the chamber F of vessel A. In the lower part of the chamber H. there is a ring
or other shaped atmospheric gas burner N, for heating the series of tubes O, and
in the upper part of it there is a conduit for leading off the products of combus-
tion. In the chamber F there is also a series of tubes Q suspended, and at the
lower part of the chamber there is a free way pipe or opening R from which the
distilled liquid flows to any receptacle placed to receive it. S is a gas supply pipe
to the ring burner.
The action of the apparatus is simple. Water is admitted from the cistern I by
way of the pipe K to the chamber E, and to the inside of the tubes Q and from
thence through the pipe L to the chamber G and the interior of the tubes O. The
gas is then lighted at the burner N, when the water in the series of tubes O will
be heated so as to give off steam in the chamber G. The steam so generated is led
off by the pipe M to the chamber F, where by reason of the low temperature of the
tubes caused by the cold water within them the steam is condensed and falls into
the bottom of the chamber F, from whence it is conducted away through the free
way pipe or opening R previously mentioned.
The different vessels are furnished with water gauges, and the apparatus may
be made of any suitable metal or material.
In the description of the action of the apparatus water is referred to as the
liquid to be distilled, but it will be obvious that the apparatus is not limited thereto
although some slight modifications may be required to adapt to the particular
purpose to which it is applied. It is also manifest that the tubes O may be heated
by steam, burning oil, or by a furnace below.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is,
The combination of the evaporating and condensing apparatus together with
the cistern and other appendages, as arranged and as herein described and shown
on the drawing.
