WHEREAS I'am in possession of an Invention for "IMPROVEMENTS IN THE
CONSTRUCTION AND ARRANGEMENT OF STEAM BOILERS," and have petitioned Her
Majesty to grant unto me, my executors, administrators, and assigns, Her

page_text: NOW KNOW YE, that I, the said William Edward Gedge, do hereby
declare that the following Complete Specification under my hand and seal
fully describes and ascertains the nature of the said Invention, and the manner
in which the same is to be performed
The object of this Invention is the construction of an improved steam boiler
intended to reduce the power which produces the caloric.
On the accompanying Sheet of Drawing forming part of this Specification,
No. 1 indicates a tube, on which come the bars No. 2. No. 3 is a horizontal
fire-place forming boiler tube, with three columns, No. 4, on which rests the
boiler No. 5, which communicates water to them. The flame leaving the
fire-place passes between the horizontal boiler tubes No. 3 and the boiler
No. 5 to the back, then passes through the tube No. 6, from there to No. 7,
and thence to Nos. 8 and 9, and by a single current which permits the pre-
servation of the caloric without interrupting the draught in consequence of
the large proportions. No. 10 is a plate, of which there is one front and back,
with holes, which come opposite the tubes, and are opened to cleanse them.
No. 11 indicates a plate, of which there are two fitted on No. 3 and No. 5
joining the plate No. 10, and forming an hermetical joint. No. 1 is furnished
with a plate held by buttons, and used to remove the tartar from the bars No. 2
without removing them.
This novel description of boiler may be applied in lieu of any other steam
boiler; it may be made of any size and for any steam pressure by following
the ordinary rules of proportion. The parts Nos. 1, 2, and 3 may be applied
to every sort of furnace, kitchen fire-place, and others, inasmuch that they
replace bricks as well as the usual bars.
In witness whereof, I, the said William Edward Gedge, have hereunto
set my hand and seal, this Twenty-first day of February, in the year
of our Lord One thousand eight hundred and sixty-six.
W. E. GEDGE. (L.B.)
