2nd. In the addition of a water reservoir placed at the bottom of
the generator, and receiving the supply of water, which by passing into
the collectors ultimately reaches the vertical boilers. This reservoir is
intended to collect the salts and solid matters of all sorts which
may be
deposited by the water that is subjected to the boiling operation. To
this end a system of supplementary boilers force the water to circulate
continuously from the above-named reservoir to those parts which may
be more particularly called the boiler, and then the water returns to the
reservoir, and so on continuously. The speed of the circulation of the
water is great in the collectors where the water is subjected to boiling,
but is almost nil at the bottom of the reservoir, so that it is in this last
that all the deposit of solid matters naturally takes place, this being a
part of the apparatus where their presence cannot produce any
derangement, and from which these solid matters may be partially
removed with the greatest facility in small quantities at a time while the
generator is at work, or entirely when the fire is extinguished and the
boiler is opened for claiming.
The vertical boilers terminate in a series of horizontal tubes or
chambers, similar in form and arrangement to the water collectors, and
into these horizontal tubes or chambers the steam ascends, and is
conducted to the steam reservoir, from whence it is taken and supplied
to the engine. This reservoir is provided with a safety valve.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Edward Newton in the Great Seal Patent
Office on the 22nd January 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the 3
County of Middlesex, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Pätent, bearing date the Twenty-second day of July, in the
year of our Lord One thousand eight hundred and seventy-three, in the

page_text: thirty-seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Edward Newton, Her special
license that I, the said William Edward Newton, my executors, adminis-
trators, and assigns, or such others as I, the said William Edward
Newton, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN STEAM GENERATORS," being a communication to me from
abroad by Albert Michel Jouet Pastré, Representative of the Société
Nouvelle des Forges et Chantiers de la Méditerranée, of Paris, in the
Republic of France, upon the condition (amongst others) that I, the said
William Edward Newton, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Edward Newton, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the Drawings here-
unto annexed, and to the letters and figures marked thercon (that is to
say) :-
This Invention of improvements in steam generators consists,―
First. In the addition of screens or diaphragms placed horizontally
between the vertical boilers, and so arranged as to force the heated gases
to circulate across and around the boilers in order to reach the chimney
which starts from the fire-box, which is arranged at the centre of the
group of boilers belonging to each fire-place.
Second. In the addition of a water reservoir placed at the bottom of
the generator, and receiving the supply of water, which, by passing into
the collectors ultimately reaches the vertical boilers. This reservoir is
intended to collect the salts and solid matters or sediment of all sorts
which may be deposited by the water that is subjected to the boiling
operation. To this end a system of supplementary boilers force the

page_text: water to circulate continuously from the above-named reservoir to those
parts which may be more particularly called the boiler, and then the
water returns to the reservoir, and so on continuously. The speed of
the circulation of the water is great in the collectors where the water is
subjected to boiling, but is almost nil at the bottom of the reservoir, so
that it is in this last that all the deposit of solid matters naturally takes
place, this being a part of the apparatus where their presence cannot
produce any derangement, and from which these solid matters may be
partially removed with the greatest facility in small quantities at a time,
while the generator is at work, or entirely when the fire is extinguished
and the boiler is opened for cleaning.
The vertical boilers terminate in a series of horizontal tubes or
chambers, similar in form and arrangement to the water collectors, and
into these horizontal tubes or chambers the steam ascends, and is
conducted to the steam reservoir, from whence it is taken and supplied
to the engine. This reservoir is provided with a safety valve.
.
In the accompanying Drawing Fig. 1 represents a sectional clevation
of the boiler complete; Fig. 2 is a transverse vertical section of the
same taken in the line 1, 2, of Fig. 1; Fig. 3 is a horizontal section
taken in the line 3, 4, of Fig. 2.
a, a, are the small vertical heating vessels, which are put in com-.
munication with each other by means of the water tubes b, b. The
upper ends of the vertical vessels a, a, are also put in communication
with each other by means of the steam collecting tubes c, c, which
terminate at one end in the steam reservoir d, which is common to the 2
whole group of collecting tubes c. A large tube e serves to receive the
return water and conduct it back to the tubes b, b. Another large
tube e¹ receives the supply of water and connects the tubes b, b, together.
It also serves as a mud space to receive the deposit from the salts and.
other solid matters which are precipitated from the water. e¹¹ are 3
heating vessels, which set up a circulation of the water by drawing it
from the tube e¹, and forcing it forward into the tube e, thus causing it
to return to the tubes b, from whence it passes again into the tube e³,
and so on continuously. The vertical vessels a, a, are connected to the
water tubes b, b, by junction pieces f,f. Similar junction pieces g, g, a
connect the upper ends of the vertical vessels a with the horizontal
steam collecting tubes c, c. The water level through all the series of
tubes is seen at h. Openings provided with steam-tight covers i are so
"

page_text: arranged that the interior of the tubes b, b, may be examined. 1, 1, are
similar openings and covers to admit of the tubes c, c, being examined,
and j, j, are another set of covers adapted to the vertical vessels a, a, for
the same purpose. The steam is taken from the boiler through the
pipe k, and is the safety valve; m is the water gauge tube, and n a
blow-off cock placed near the water level. In Fig, 1o is another blow-
off cock placed at or near the bottom of the boiler. p is the water
supply pipe, and q the furnace or fire-place, and is the ash-pit. The
whole of the generator is surrounded with an envelope s made of sheet
iron and brickwork, which encloses the fire-place and ash-pit, and keeps
the heated gases confined among the tubes of the generator. t, t, are
horizontal screens for controlling the circulation of the gases round the
heating tubes; u is a hood or dome for conducting the gases to the
chimney v.
Having now described the improvements in steam generators which
have been communicated to me by my foreign correspondent, and having
explained the manner of carrying the same into effect, I claim as the
Invention secured to me by Letters Patent as aforesaid, the combination
and arrangement of parts herein set forth, whereby the heated gases
from the fire-place are forced to circulate around the water heating
vessels, and thus made to part with their heat before reaching the
chimney.
I also claim adapting to the lower part of the steam generator a water
reservoir to which the feed water is supplied, and which also serves
as a space for collecting the solid matters which are deposited from the
water.
In witness whereof, I, the said William Edward Newton, have
hereunto set my hand and seal, the Twenty-second day of
January, in the year of our Lord One thousand eight hundred and
seventy-four.
