MENTS IN GENERATING STEAM," to be as follows:-

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of March, in the year of our Lord
One thousand eight hundred and fifty-six, in the nineteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Joseph Webber, Her special licence that I, the said Joseph Webber, my
executors, administrators, and assigns, or such others as I, the said Joseph
Webber, 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 GENE-
RATING STEAM," upon the condition (amongst others) that I, the said Joseph
Webber, my executors or administrators, by an instrument 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 Joseph Webber, do hereby declare the
nature of my 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, reference being had to the Drawings hereunto annexed, that is
'to say:-
"
$
: In the burning of lime, chalk, and cement, the heat generated is allowed
to go to waste; now the object of my Invention is, to utilize this heat by
-surrounding that part of a kiln where there is the greatest amount of heat
by a cylindrical or annular boiler in which steam is generated.
In the Drawings annexed Figure 1 is a sectional elevation of a kiln fitted
with a steam boiler, and Figure 2 is a plan. A, A, is the brickwork of the
kiln; B, B, an annular boiler; between the outside of the boiler and the kiln is
a lining of any suitable non-conducting material, or, instead of this lining, a flue
C, C, as shewn in Figure 3, may be carried round the outside of the boiler,
but in such case coal or wood must be used to burn the lime, and fire must
always be kept below the passage D leading into the flue, or the top of the
kiln must be entirely closed when burning is going on. Various forms and
arrangements of kilns may be employed, and different materials may be used
as fuel to burn the lime and similar materials with. I have simply shewn by
way of exemplification a manner in which my Invention may be carried into
effect.

page_text: And having now described the nature of my said Invention, and in what
manner the same may be performed, I declare that I claim the employment of
the heat produced by and in the burning of lime, and similar materials to
generate steam.
In witness whereof, I, the said Joseph Webber, have hereunto set my
hand and seal, this Fifteenth day of September, One thousand eight
hundred and fifty-six.
Witness,
JOHN O. WILLIAMS,
Ironmonger, Torquay.
JOSEPH WEBBER. (L.S.)
