Year: 1869

page_text: LETTERS PATENT to William Edward Gedge, of the Firm of John
Gedge and Son, of No. 11, Wellington Street, Strand, in the
County of Middlesex, Patent Agent, for the Invention of "AN
IMPROVED METHOD OF AND APPARATUS FOR GENERATING STEAM." -A com-
munication from abroad by Auguste Butin-Denniel, of 37, Boulevard
Bonne Nouvelle, Paris, France, Sugar Baker.
Sealed the 14th January 1870, and dated the 19th July 1869.
PROVISIONAL SPECIFICATION left by the said William Edward Gedge
at the Office of the Commissioners of Patents, with his Petition, on
the 19th July 1869.
I, WILLIAM EDWARD GEDGE, of the Firm of John Gedge and Son, of
No. 11, Wellington Street, Strand, in the County of Middlesex, Patent
Agent, do hereby declare the nature of the said Invention for "AN
IMPROVED METHOD OF AND APPARATUS FOR GENERATING STEAM," a communication
to me from abroad by Auguste Butin-Denniel, of 37, Boulevard Bonne
Nouvelle, Paris, France, Sugar Baker, to be as follows:-
This Invention consists in reproducing steam by steam by means of
a worm with large heating surfaces which causes the water in the

page_text: apparatus to boil. The steam of this water passes to and is stored in a
steam chamber or reservoir up to a pressure of four or five atmospheres
and may be used from thence as required.

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Edward Gedge in the Great Seal Patent
Office on the 18th January 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM

of our Lord One thousand eight hundred and sixty-nine, in the thirty-

and grant unto me, the said William Edward Gedge, Her special licence
that I, the said William Edward Gedge, my executors, administrators,
and assigns, or such others as I, the said William Edward Gedge, 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 "AN IMPROVED
METHOD OF AND APPARATUS FOR GENERATING STEAM," a communication to me
from abroad by Auguste Butin-Denniel, of 37, Boulevard Bonne
Nouvelle, Paris, France, Sugar Baker, upon the condition (amongst
others) that I, the said William Edward Gedge, 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

page_text: 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 William Edward Gedge, 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, reference being had to the accompanying
Drawing, and to the letters of reference placed thereon :-
This Invention consists in reproducing steam by steam by means of
worm with large heating surfaces which causes the water in the
apparatus to boil. The steam of this water passes to and is stored in a
steam chamber or reservoir up to a pressure of four or five atmospheres
and may be used from thence as required.
On the acompanying diagram A indicates the main generator; B,
valves; C, float; D, steam guage; E, apparatus in which steam is
generated by steam; F, support of apparatus E bolted to generator A;
G, steam entrance; H, worm; I, steam return; J, feed pipe; K, water
guage; L, man-hole of apparatus; M, pipe leading to steam chamber
or reservoir; N, steam reservoir; O, valves; P, steam guage; Q, steam
pipes; R, blow-off cock.
Claim is made to the use of a worm applied to a generator and in
combination with a reservoir in which the steam generated by means of
the worm accumulates to be used as required, substantially as hercin-
before described and illustrated on the annexed Sheet of Drawing.
In witness whereof, I, the said William Edward Gedge, have here-
unto set my hand and seal, this Eighteenth day of January, in the
year of our Lord One thousand eight hundred and seventy.
