IMPROVEMENTS IN FEED WATER HEATING APPARATUS FOR STEAM BOILERS
Year: 1873

page_text: LETTERS PATENT to Joseph Bennett, of Birkenhead, in the County
of Chester, Engineer, for the Invention of "IMPROVEMENTS IN FEED
WATER HEATING APPARATUS FOR STEAM BOILERS."
Scaled the 29th July 1873, and dated the 30th January 1873..
PROVISIONAL SPECIFICATION left by the said Joseph Bennett at the
Office of the Commissioners of Patents, with his Petition, on the
30th January 1873.
I, JOSEPH BENNETT, of Birkenhead, in the County of Chester,
Engineer, do hereby declare the nature of the said Invention for "Im-
PROVEMENTS IN FEED WATER HEATING APPARATUS FOR STEAM BOILERS," to be
as follows:-
The object of my Invention is to provide simple and durable apparatus
(suitable for boilers generally, but specially so for marine boilers) for
heating water to a high temperature during its passage, as feed to steam
boilers. For this purpose I employ apparatus which for convenience
may be shortly described as a metallic pipe; a series of pipes may be
used disposed and applied in a novel manner. The said apparatus is

page_text: connected at its outer end to the feed pump, feed appliance, or source of
supply; it is led through the ash-pit as near to the fire-bars as possible,
thence through or over the bridgo, and afterwards upwards vertically or
nearly so in the fire-box, combustion chamber, or space for heating gases
into the boiler under the water linc. A perforated check valve is
applied to the end of the pipe inside the boiler if desired.
It will be obvious that my said apparatus receives a moderate heat in
the ash-pit, and is highly heated in the fire-box or its equivalent. In
this way the water in its passage to the boiler is gradually heated to the
required temperature.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph Bennett in the Great Seal Patent Office
on the 30th July 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
BENNETT, of Birkenhead, in the County of Chester, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of January, in the year
of our Lord One thousand cight hundred and seventy-three, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Joseph Bennott, Her special licence
that I, the said Joseph Bennett, my executors, administrators, and
assigns, or such others as I, the said Joseph Bennett, 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, excrcise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN FEED WATER HEATING APPARATUS FOR STEAM BOILERS," upon the condition
(amongst others) that I, the said Joseph Bennett, my exccutors or
administrators, by an instrument in writing under my, 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

page_text: within six calendar montlis next and immediately alter the date of the
said Letters Patent.
NOW KNOW YE, that I, the said Joseph Bennett, do hereby declare
the nature of said Invention, and in what manner the same is to
bo performed, to be particularly described and ascertained in and by
the following statement, reference being had to the accompanying Sheet
of illustrative Drawings, and to the figures and letters marked thereon,
that is to say:-
The object of my Invention is to provide simple and durable apparatus
suitable for boilers generally, but specially for marine boilers for
heating water to a high temperature during its passage as feed to steam
boilers.
For this purpose I employ apparatus which for convenience
may be shortly described as a metallic pipe; a series of pipes may be used
disposed and applied in a novel manner. The said apparatus is connected
at its outer end to the feed pump, feed appliance or source of supply;
it is led through the ash-pit as near to the fire-bars as possible, thence
through or over the bridge, and afterwards upwards vertically or nearly
so in the fire-box, combustion chamber, or space for heating gases into
the boiler under the water line. A perforated check valve is applied to
the end of the pipe inside the boiler if desired.
It will be obvious that my said apparatus receives a moderate heat in
the ash-pit, and is highly heated in the fire-box or its equivalent. In
this way the water in its passage to the boiler is gradually heated to tho
required temperature.
The Sheet of Drawings herewith contains a view in longitudinal section
of a portion of a marine boiler, with fire-grate, and bridge, and feed
water heating apparatus, arranged and disposed in accordance with my
Invention.
A, boiler; B, fire-bars; C, bridge; D, metallic feed and heating pipc

fire-bars B through the bridge C, and upwards in the combustion
chamber into the boiler. A hinged valve G is placed on the top of
the pipe within the boiler to prevent return of water when the feed
pump or appliance is standing. The hinged valve shown is preferable;
it may be placed in the pipe D instead of on the end of same. To
ensure efficient circulation when the feed is stopped, the small pipe H
