Improvements in Apparatus for Condensing Steam.
I, HOWARD THEOPHILUS WRIGHT, of 16 Great George Street, in the City
f Westminster, Engineer, do hereby declare the nature of this invention to be
s follows:-
My invention relates to apparatus for condensing steam, & has for its object
o provide an apparatus which is economical in first cost and maintenance, and
which will condense a large volume of steam and secure a good vacuum with the
consumption of but a small quantity of condensing water.
for re-use.
According to my invention I provide a number of vertical tubes with their upper
ends opening into a box, or boxes, into which the steam to be condensed is
introduced, and with their lower ends opening into a box, or boxes, in connection
with the air pump. The said tubes are preferably of brass, or copper, or some
alloy thereof. Surrounding the upper parts of the tubes, or each group of tubes,
is a trough, or vessel, into which the condensing water is passed the said tubes
passing through openings in the bottom, or bottoms, of the trough, or vessel, or
troughs, or vessels, the said openings being of such a size that a very small space
is left between them and the exteriors of the tubes passing therethrough, so that
a thin film of water will pass down over the exteriors of the tubes, and be
received in a receptacle, or receptacles, beneath from which it can be pumped back
The proper relative positions of the tubes and water troughs or
vessels may be secured by distance pieces, or otherwise, to maintain the proper
space around each tube. The apparatus is surrounded by a casing which may be
provided with a chimney, or shaft, or other means for creating sufficient current
of air to carry off vapour arising from the condensing water in its passage over
the exteriors of the tubes. I preferably arrange the tubes in groups extending
from side to side of the casing by which the apparatus is enclosed there being for
each group of tubes at top a box for the admittance of steam and at bottom, a box
for the water of condensation, branches from the steam inlet pipe being carried to
each upper box and branches to the air pump being carried from each lower box
and the vessels for receiving the water are arranged as troughs beneath the steam
admission boxes and branches lead to each from a pipe from the water supply
which may be a tank above, into which water which has run down the outsides
of the tubes and been received in the vessels beneath may be pumped back the
said vessels beneath being also in the form of troughs one common to each group
of tubes, and having an outlet branch leading to the inlet of the pump by which
the water is returned to the tank above. The spaces between the tubes and
boxes and troughs are sufficient to allow of the proper passage of air through the
apparatus.

I, HOWARD THEOPHILUS WRIGHT, of 16 Great George Street in the City of
Westminster Engineer, 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 apparatus for condensing steam, and has for its object
to provide an apparatus which is economical in first cost and maintenance an
which will condense a large volume of steam and secure a good vacuum with the
consumption of but a small quantity of condensing water.
I will describe my invention with reference to the accompanying sheet of
drawings wherein Figure 1 is an end elevation, Figure 2 a side elevation,
Figure 3 a transverse section and Figure 4 a plan (partly in section on the
line 1. 2 Figure 2) of an apparatus constructed in accordance with my
invention.
I provide a number of vertical tubes a with their upper ends opening into a
box into which the steam to be condensed is introduced by a pipe attached at 62
the lower ends of the said tubes a opening into a box c in connection with the
air pump by a pipe attached at c. The said tubes a are preferably of brass, or
copper, or some alloy thereof. Surrounding the upper parts of the said tubes a or
each group of tubes, is a trough, or vessel d, into which the condensing water is
passed the said tubes a passing through openings d in the bottom, or bottoms, of
the trough, or vessel, the said openings being of such a size that a very small
space is left between them and the exteriors of the tubes a passing therethrough,
so that a thin film of water will pass down over the exteriors of the tubes a and
be received in a receptacle e, beneath from which it can be pumped by a pipe
attached at e back to the trough or vessel, d for re-use. The proper relative
positions of the tubes a and the water trough d may be secured by distance pieces
and interceptors such as those shewn at may be used to assist in distributing the
water over the tubes, or otherwise, to maintain the proper space around each tube a.
Although I have shewn but one box at b and at c and one trough d and one
receptacle e there may in each case be more than one if desired with tubes .a
arranged in connection therewith. The apparatus may be left open as shewn or it
may be surrounded by a casing which may be provided with a chimney, or shaft,
or other means for creating sufficient current of air to carry off vapour arising
from the condensing water in its passage over the exteriors of the tubes. I may
arrange the tubes in groups extending from side to side of this casing there being
for each group of tubes at top a box for the admittance of steam and at bottom
a box for the water of condensation, branches from the steam inlet pipe being
carried to each upper box and branches to the air pump being carried from each
lower box the vessels for receiving the water being arranged as troughs beneath
the steam admission boxes, branches leading to each from a pipe from the water
supply which may be a tank above, into which, water which has run down the
outsides of the tubes a and been received in the vessels e beneath, may be pumped
back, the said vessels e beneath, being also in the form of troughs one common to
each group of tubes and having an outlet branch leading to the inlet of the pump
by which the water is returned to the tank above. The spaces between the
tubes and boxes and troughs are sufficient to allow of the proper passage of air
through the apparatus.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
Apparatus for condensing steam the said apparatus being constructed or
arranged substantially as herein before described and illustrated in the accompanying
drawings.
