BOILERS.
PROVISIONAL SPECIFICATION left by the said John Box at the
Office of the Commissioners of Patents, with his Petition, on
the 26th May 1853.
I, JOHN Box, of 27, Rue Pepiniere, Brussels, in the Kingdom of
Belgium, Furnishing Engineer, do hereby declare the nature of the
said Invention of "IMPROVEMENTS IN SUPILYING WATER TO STEAM-EN-
GINE BOILERS to be as follows:-
This Invention consists of causing the water with which the boiler
is fed to circulate through pipes contained in the smoke box and
chimney, so that it may become heated before it is supplied to the
boiler.

filed by the said John Box in the Great Seal Patent Office on
the 7th March 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
JOHN Box, of 27, Rue Pepiniere, Brussels, in the Kingdom of Belgium,
Furnishing Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of May, in the
year of our Lord One thousand eight hundred and fifty-three, in the
sixteenth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said John Box, Her special
licence that I, the said John Box, my executors, administrators, and
assigns, or such others as I, the said John Box, 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 SUPPLYING WATER TO STEAM-ENGINE BOILERS," partly communicated
to me from abroad, and partly invented by myself, upon the condition
(amongst others) that I, the said John Box, by an instrument in writing
under my hand and seal, 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 John Box, 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 thereof (that is to say):
This Invention consists of causing the water with which the boiler
is fed to circulate through pipes contained in the smoke box and
chimney, so that it may become heated before it is supplied to the
boiler.

page_text: Having thus stated the nature of the said Invention, I will proceed
to describe the manner of performing the same.
DESCRIPTION OF THE DRAWING.
Figure 1, shows a section of the chimney and smoke box of a loco-
motive engine boiler with a coiled pipe thereon. Figure 2, shows a
similar section with a tube bent in different directions. And I would
state that the form of the tube a, within the chimney may be varied so
long as the same is suitable for carrying out the objects of the Inven-
tion. The water supplied to the steam boiler to which such apparatus
may be applied, in place of being pumped directly into the boiler, is to
be forced through the pipe a, by which it will become highly heated by
the heat which would otherwise pass into the atmosphere; and it is the
application of apparatus or tubes a, a, in the chimney and smoke box
of steam boilers for the purpose of heating the supply water in its
passage to the boiler which constitutes the Invention.
In witness whereof, I, the said John Box, have hereunto set my
hand and seal, this Twenty-first day of November, in the year
of our Lord One thousand eight hundred and fifty-three.
Witness,
ROBERT W. RUSSELL,
82, Chaussée de Wavre,
