Year: 1870

page_text: LETTERS PATENT to Alfred Alexander and David Lansley, of
1.
Cirencester, in the County of Gloucester, Mechanical Engineers,
for the Invention of "IMPROVEMENTS IN WATER HEATERS AND FEEDERS."
Sealed the 17th January 1871, and dated the 25th August 1870.
PROVISIONAL SPECIFICATION left by the said Alfred Alexander and
David Lansley at the Office of the Commissioners of Patents, with
their Petition, on the 25th August 1870.
We, ALFRED ALEXANDER and DAVID LANSLEY, of Cirencester, in the
County of Gloucester, Mechanical Engineers, do hereby declare tho
nature of the said Invention for "IMPROVEMENTS IN WATER HEATERS AND
FEEDERS," to be as follows:-
The improvements have reference to water heaters and feeders intended
for portable and other steam engines, and consist in forming such heaters
of an annular or ring-shaped chamber or chambers conveniently the
same diameter internally as the barrel of the boiler to which they may
be applied, and so that the outside cylindrical or other shape of the

page_text: boiler may be prolonged throughout the whole length of the smoke box,
such chamber or chambers being made to hold a convenient quantity of
water according to the size of the engine, and so constructed that the
smoke passing through them is exposed to a large area, and furnished
with a suitable passage way, preferably at the top, for the passage of the
smoke from the flues thro' the chimney, also with suitable feed pipes for
the entrance of the cold water and the exit of the hot from the heater to
the boiler.
Further, the improvements embrace the addition to the heater of a
pump, having a double valve box to be used for pumping water into the
heater, and by shutting off the communication between the feed water
and the heater also be used for simultaneously opening a communication
between the heater and the boiler.
The improvements may be carried-into-effect by constructing the
chambers above mentioned so that they shall surround and form the
smoke box; they may be made of wrought iron or of metal rivetted or
otherwise fixed; to the bottom or under side may be affixed a metal
feed pipe for the passage of cold water, which after being heated to a
sufficient temperature by the passage of the gasses and smoke will be
forced through an exit pipe preferably fixed at or near the top connected
with the boiler. The pump may be of the ordinary construction but
furnished with a double valve box and with suitable connections.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Alfred Alexander and David Lansley in the Great
Seal Patent Office on the 4th February 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ALFRED
ALEXANDER and DAVID LANSLEY, of Cirencester, in the County of
Gloucester, Mechanical Engineers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fifth day of August, in the year
of our Lord One thousand eight hundred and seventy, in the thirty-fourth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto us, the said Alfred Alexander and David Lansley, Her special
licence that we, the said Alfred Alexander and David Lansley, our
executors, administrators, and assigns, or such others as we, the -said

page_text: Alfred Alexander and David Lansley, our 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 WATER HEATERS AND
FEEDERS," upon the condition (amongst others) that we, the said Alfred
Alexander and David Lansley, our executors or administrators, by an
instrument in writing under our, or their, or one of their hands and
scals, 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 we, the said Alfred Alexander and David
Lansley, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and
ascertained in and by the following statement, that is to say:-
The improvements have reference to water heaters and feeders intended
for portable and other steam engines, and consist in forming such heaters
of an annular or rigt-shaped chamber or chambers conveniently the
same diameter internally as the barrell of the boiler to which they may
be applied, and so that the outside cylindrical or other shape of the
boiler may be prolonged throughout the whole length of the smoke box,
such chamber or chambers being made to hold a convenient quantity
of water according to the size of the engine, and so constructed that the
smoke passing thro' them is exposed to a large area and furnished with
a suitable passage way preferably at the top, for the passage of the smoke
from the flues thro' the chimney, also with suitable feed pipes for the
entrance of the cold water and the exit of the hot from the heater to
the boiler.
-
Further the improvements embrace the addition to the heater of a
pump having a double valve box to be used for pumping water into the
heater, and by shutting off the communication between the feed water
and the heater also be used for simultaneously opening a communication,
between the heater and the boiler.
The improvements may be carried into effect by constructing the.
chambers above-mentioned so that they shall surround and form the

page_text: smoke box; they may be made of wrought iron or of metal rivetted or
otherwise fixed; to the bottom or under side may be affixed a metal feed
pipe for the passage of cold water, which after being heated to a sufficient
temperature by the passage of the gasses and smoke will be forced through
an exit pipe preferably fixed at or near the top connected with the boiler.
The pump may be of the ordinary construction, but furnished with a
double valve box and with suitable connections.
The accompanying Drawings will serve to illustrate a convenient mode
of carrying our Invention into effect.
Sheet 1 shows the general arrangement of heater, and also the means
of feeding the boiler, through the pipe A, which is preferably connected
as near as possible to the top of the heater. At the junction of the pipe A
with the boiler a pipe B or in some cases a continuation of-the-pipe-A-
is carried down into-the-boiler to a distance preferably of about two or
three inches below the lowest level at which the water stands in the boiler,
thus providing for the escape, (on first filling the heater) of all air and
steam, and ensuring that the heater shall be filled with water only. As
it is essential that the heater should not be open all round, and so allow
of the direct passage into the boiler of the cold water when first pumped
into the heater the heater may be and is intended to be constructed
with an intercepting piece C placed at the top, thus causing the water
to pass from the point D where it enters the heater to the point E where
it leaves it, thus becoming thoroughly heated during its passage. The
fore carriage of the engine (I) is also constructed and furnished with a
ball and socket or cup K, which is attached to the boiler, a chamber or
recess L is formed which is open to the heater and in which the mud or
other sediment from the water may collect and be discharged from time
to time as required by means of the blow off cock M, a plate F is
provided for the purpose of cleaning out the heater.
Sheet 2 of the Drawings shows a heater constructed either of wrought
or cast iron which can be easily adapted to any existing boiler by simply
fixing it inside an ordinary smoke box and adjusting the pipes as shown
on Sheet 1.
The further improvements, namely the double valve box, is shown on
Sheet 3. A is the section pipe from the reservoir or pond or receptacle
in which the water may be required to be drawn; B is the delivery pipe
into the boiler; C is the delivery pipe into the heater; D, the suction
pipe from the heater; E is the connection with the pump; F, are

page_text: handles connected by coupling rod M, turning H and I, which are three
way cocks; K and L are ball valves. In Figure I., Sheet 3, the pump is
shown as drawing water from the heater and forcing it into the boiler
after being heated. When the cocks are reversed as shown at F and
G by colored lines the pump draws from the tank or reservoir and pumps
into the boiler; Figure 2 shows an top view, and Figures 3 and 4
different details of the double valve box.
In witness whereof, we, the said Alfred Alexander and David
Lansley, have hereunto set our hand and seal, this Third day
of February, in the year of our Lord One thousand eight hundred
and seventy-one.
