Year: 1885

do hereby declare the nature of my invention for AN IMPROVED CONDENSER FOR
SEA WATER DISTILLING APPARATUS to be as follows:—
I make my Condenser in the form of a square box into which is cast or fitted
five or more division plates standing out horizontally from each side two thirds the
width of box. The Condenser has a cover on one side & flauged pipe on top for
stean inlet & two flanged pipes on side for circulating water. The steam tube is
made in the shape of a Bat case with half round edges, The top end of which is
jointed to under side of top of Condenser, (from where the steam is supplied) it is
then so snaked or bent as to pass over & under the several division plates, (leaving
a space between for circulating water) untill it reaches the bottom of Condenser
where it is jointed to lead into Filter, The circulating water then passes on each
side of flat steam tube, (begining at bottom of Condenser) & over & under each
division plate & corresponding bend in Tube till it reaches overflow pipe on top
sido of Condenser. The advantage claimed is the great amount of cooling surface
gained through using a flat case Tube, & the mode of circulating the water through
Condenser.

JOHN LEITCH of 44 Chantilly Road Custom House, Victoria Docks, E. do hereby
declare the nature of my invention for "IMPROVED CONDENSER FOR SEA WATER
DISTILLING APPARATUS" and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
I make my Condenser of suitable material in the form or shape of a square box
or case and of the necessary proportions, in which I fit or provide a series of
division plates cast therewith or otherwise, say for example five or more in number
standing out horizontally from each side about two thirds of the width of the box
or case. The Condenser has a cover on one side or face thereof provided, also a
flanged pipe on the upper portion for the admission of steam, likewise two flanged
pipes on the side for the circulating water. The steam tube, passage or connection
is by preference made in the shape of a flat case with half round edges, the upper
end of which is jointed or connected to the under side of the top of the Condenser
and to the flanged pipe from whence the steam is admitted or supplied, it is then
so "snaked" curved or bent as to pass over and under the several division plates,
leaving a suitable space between for the circulating water to pass freely, until it
reaches the bottom of the Condenser where it is connected and leads towards the
lower portion or filter arrangement. By this arrangement the circulating water is
made to pass around each flat side or surface of the steam tube, passage, or connec
tion and over and under cach of the division plates and corresponding bend of the
tube, tubes, passage or passages as may be provided until it reaches the overflow
or outlet pipe on the top or upper part of the Condenser.
In tho accompanying Drawing, Figure 1, is a sectional view and Figure 2, a
plan or external view of a form of Condenser externally arranged in the form of a
square case or box (altho' other shapes or forms may be employed to suit the
particular circumstance or case required) in which a series of division plates A., of
any suitable number are arranged according to the size and proportion of the
Condenser and the particular object for which it is intended to be used, but for
ordinary purposes five or more division spaces may be employed protruding or
standing out, horizontally by preference from end to end and alternately from each
side and formed or cast with the case or box of the upper chamber B, somewhat
similar to that shewn in the drawing.
The circulating water is led or forced in or through by any suitable means into the
internal pipes or tubes C as at Fig. 1, by means of the connection or inlet D, Fig. 2.
The internal pipes E-as at Fig. 1, are for the overflow or discharge through the
outlet F, Fig. 2.
I provide a cover on one side or face of the Condenser box or case so arranged as
to be secured in position by means of Bolts or otherwise as shewn at Fig. 2, which
may have the inlet D, and outlet flanges F, cast or secured therein and so arranged
for connection to the internal tubes C, C and E, E as shewn in the section Figure 1;
G is a flanged pipe connected and communicating with either the Main or Donkey
Boiler, or Boilers at whatever the pressure of steam may be therein and is lead to
a series of flattened or hollow tubes or steam spaces H, bent or curved so as to pass

page_text: over and under the several division plates A, leaving a free space for the circulating
water to pass around, until it reaches the bottom of the Condenser where it is
jointed or coupled thereto and leads into the filter or lower case H, which I form or
cast by preference of a square or other, suitable form to correspond with the upper
case or box B. In the lower case or box H, I place a perforated plate J at the
upper portion of the same and a similar perforated plate, curved or otherwise K, at
the lower portion thereof as shewn at Fig. 1, the intention being to place in the
space thus formed suitable filtering material such as Charcoal, Shingle, Cotton or
other material or mixture as may be found most suitable, and thro' which the Sea
Water in its condensed state is forced or passed through until it reaches the bottom
space L, from which it emerges or flows through the pipe or connection (or con-
nections) M into tanks or otherwise.
It will thus be seen that I form and provide a very simple and effective
Condenser wherein the circulating water is caused to freely pass on and over each
Bat side of the steam space or flattened Tube or Tubes and over and under each
division plate and corresponding bend of the steam space or flattened Tube, or
Tubes until it reaches the overflow pipe, or pipes, arranged at the upper portion of
the Condenser Case or Box.
.
Figures 3 and 4, exhibit a cross section of the flattened steam spaces or Tubes H,
shewn in Fig. 1, which may be divided in their width or formed seperately so as
to divide the passage of the steam in passing through the same or be formed of one
space only.
Figure 5, is an elevation of the flanged pipe or connection for the steam entry
where a Valve would be provided for regulating or closing its admission.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed and illustrated the
same I declare that what I claim is
The advantage gained through employing a flattened steam Tube, Tubes, space
or spaces, as the case may be, curved or bent around a series of division plates
alternately arranged on each side of the box or case as herein described, producing
a very large amount of surface throughout for the particular purpose intended
also the mode of circulating the water through the Condenser substantially as
herein illustrated and described, but the general arrangement of which may be
slightly modified to suit particular purposes.
