for Heating Purposes and for Feeding Boners.
We, CHARLES HOWE of Granville Cottage Kendal Road Colchester in the County
of Essex Master Mariner and JOSEPH HAWKINS BECKWITH of Hythe Hill Colchester
aforesaid Ship Owner, 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 relates to improvements in apparatus for distilling water and for
feeding boilers part of the sail apparatus being also applicable for heating purposes
and is designed to effect those results in a cheap, simple and efficient manner.
a
According to this invention live steam from the main boiler is passed through
coiled tube or pipes placed within a vessel of any suitable shape containing the salt or
impure water to be distilled (hereinafter calleil the secondary boiler) and is there
condensed and made to flow back to the boiler by a pipe or pipes provided with an
air escape tube and chamber.
The heat given off by the condensation of the live steam boils the impure water
contained in the secondary boiler. The secondary steam thus generated is passed
through a coiled tube contained within a chamber of any suitable shape through which
cold water is constantly circulating, and is there condensed and may be led into the
main condensor of a steam engine if any or when drawn off may be fed into the boiler
to supply the loss, or used for washing or other purposes, or filtered and made fit for
drinking.
The impure water for distillation is led from any suitable head of water into the
bottom of the condensing chamber and discharged from the top thereof into a pipe
leading to the secondary boiler, where it arrives in a heated condition, having absorbed
during its passage through the condensing chamber the heat given off by the con-
densation of the secondary steam. It will thus be seen that the water produced by
the condensation of the live steam is at a temperature very little below boiling point
and hence the manifold disadvantages of feeding cold water into the main boiler are
obviated and that none of the water in the main boiler is wasted in the process.
Part of the apparatus hereinbefore described may be used for raising or maintaining

page_text: the temperature of the wort in the vat of a brewery, or of the water or other substance
contained in any cask, tank fub or other receptacle used in laundries or such like
places by passing live steam from a boiler through a coiled or straight tube or tubos
placed within the said vat, cask, tank tub, or other receptaelo and fooling the
rondensed water so produced back to the boiler by a pipe or pipes provided with an
air escape tube.
And in order that our invention may be more fully understood and carried into
practice we will now proceed to describe the same with reference to the accompanying
drawings in which similar letters indicate corresponding paris throughout.
Figures 1 and 2. represent our invention as applied to marine and land boilers
rospectively.
Livo steam from the boiler A is passed by pipe C through the coiled tube B: it is
there condensed by the water contained in the secondary boiler D and flows by
gravitation through the pipes E, F, and into the main boiler A.
The pipe is fitted with a non-return valve at Z, so as to prevent the water rising
from the boiler A into the ('oil B.
To regulate the working of this part of the apparatus shut off Cocks II H1, H2
and I are provided. When II 3 is closed and the other three Cocks are open the
steam will pass through the coil, and the condensed water will be returned into the
boiler A through pipe G. To blow off any stoppage which may occur in the pipe F,
close the cork H2. and open H, H1 and 11 3. To blow off the pipe G close HI and
open H 2 and II 3
It will be readily seen that by suitably placing the pipo G the cocks II 2 and H 3
can be used as an ordinary blow off for the boiler A.
At the junction of the pipes E and Fan air chamber J provided with an air escape
tube J1 is fitted. When the mixed air and water arrive at this junction the water
will fall by gravitation down the pipe F and the air will rise and escape through the
chamber J.
The tubo J 1 is screwed to a pipe provided with a Cock J 2. to regulate the escape
of air, and also to allow the air tube to be taken off for repair when necessary without
stopping the working of the apparatus.
The secondary steam is passed by the pipe N into the coil P and the condensed
water produced therein is discharged by the pipe at O.
The water to be distilled is led by the pipe Q into the condensing chamber R. and
from thence passed by the pipe S, into the secondary boiler D Regulating Cocks T
and TL are fitted on the pipes Q and S.
The condensor R is fitted with an overflow pipe V The secondary boiler D is
provided with a scum cock K which can also he used as an overflow pipe when
required with a brine cock I, and a gnage glass M.
Figure 3. shows part of our invention as employed for raising or maintaining the
temperature of the wort in a vat W and of the water contained in a tank or
vossel X.
It will be seen that tho vat W roplaces the secondary boiler D. shown in Figures 1
and 2, and that live steam is lod from the main boiler A, condoused within the coiled or
straight pipo or pipos B and the wator produced flows into the boiler by the pipes E.
and G, and that the arrangement of the apparatus is similar to that already described
with reference to Figures 1 and 2. oxcept that a second air chamber connected by a
branch pipo e is shown which may be used in place of the air chamber J where it is
found inconvenient to allow the air to be discharged beneath the floor or ground Y
upon which the vat is standing,
Similarly the vessel X replaces the secondary boiler D, and may if desired be
furnished with a branch pipe and air chamber; to be used instead of the air chamber J
shown in the drawing all the other parts being also similarly arranged to those
shown in Figs. 1 and 2.
It is to be distinctly understood that the apparatus is so constructed that in all cases
the bottom of tho water in the secondary boiler D is above the level of the water in
the main boilor A.

page_text: 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 :-
First. The arrangement of apparatus for distilling water and for feeding boilers
combined and operating substantially as heroinbefore set forth and illustrated in
Figs. 1 and 2. of the accompanying drawings.
Second. The arrangement of apparatus for heating purposes and for feeding boilers
combined and operating substantially as hereinbefore set forth and illustrated in Fig. 3
of the accompanying drawings.
