Foreign Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street,
Manchester, both in the County of Lancaster, and 323, High Holborn, in the County
of Middlesex, Civil Engineer, do hereby declare the nature of this invention to be
as follows:
The object of this invention is a device for conveying, from steam heated
apparatus, direct back to the boiler producing the steam, without any other
mechanical aids, the steam partly remaining as such, and partly (through the
diminution of the heat) converted into water.
In carrying out the invention, a pipe is provided which conducts the steam from
the boiler into a steam chamber situated in the double bottom of the boiling down
or steam heated apparatus where it condenses as it yields up its heat and trickles back
through the said pipe. According to another arrangement, the steam is conducted
by means of pipes out of the boiler into a pipe coil or worm, and between the
double bottoms of the apparatus, and the condensed water returns to the boiler by
means of exhaust pipes.
In the first arrangement, it is of course necessary to have, in the boiler and steam
chamber, an approximately equal pressure, and an approximately equal tempera-
ture must prevail; the other apparatus, on the contrary, renders it possible for a
lower pressure and temperature to exist in the pipe coil and in the steam chamber
than in the boiler. The difference of pressure is in fact compensated for by means
of the weight of the condensed water collected in the exhaust pipe. The difference
of pressure existing in the boiler and in the steam pipe or chamber will, in every
case, equal the height of the column of condensed water in the exhaust pipes
(measured from the water level in the boiler). It results from this that, in case
a great difference of steam pressure is to be reached, the apparatus and the
boiler must be so arranged that a considerable difference of height exists between
them.

page_text: the same is to be performed, to be particularly described and ascertained in and
by the following statement :---
The object of this invention is a device for conveying, from steam heated
apparatus, direct back to the boiler producing the steam, without any other
mechanical. aids, the steam partly remaining as such, and partly (through the
diminution of the heat) converted into water.
In carrying out the invention as shown in the accompanying drawings, a pipe a
is provided, which conducts the steam from the boiler A into a steam chamber b
situated in the double bottom of the boiling down or steam heated apparatus B,
where it condenses as it yields up its heat and trickles back through the said
pipe a.
According to another arrangement, the steam is conducted by means of pipes c c
out of the boiler A into a pipe coil or worm d, and between the double bottoms e
of the apparatus C, and the condensed water returns to the boiler by means of
exhaust pipes ff.
In the first arrangement, it is, of course, necessary to have, in the boiler A. and
steam chamber b, an approximately equal pressure, and an approximately equal
temperature must prevail the other apparatus, on the contrary, renders it possible
for a lower pressure and temperature to exist in the pipe coil d and in the steam
chamber e than in the boiler. The difference of pressure is in fact compensated
for by means of the weight of the condensed water collected in the exhaust pipe f
The difference of pressure existing in the boiler A and in the steam pipe d or
chamber e will, in every case, equal the height of the column of condensed
water in the exhaust pipes f (measured from the water level in the boiler). The
result is that, in case a great difference of steam pressure is to be reached, the
apparatus C and the boiler A must be so arranged that a considerable difference of
height exists between them.
Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is :-
:-
The improvements in devices substantially as herein described and shown, for
conveying condensed water from steam heated apparatus back to the boiler
generating the steam, whereby the condensed water may be returned to the boiler
by the action of gravity alone.
