Year: 1862

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 "IMPROVED APPARATUS
FOR EXTRACTING CONDENSED STEAM."-A communication from abroad by
Gabriel Brasseur, of No. 15, Passage des Petites Ecuries, Paris,
France.
Sealed the 17th April 1863, and dated the 18th October 1862.
PROVISIONAL SPECIFICATION left by the said William Edward Gedge
at the Office of the Commissioners of Patents, with his Petition,
on the 18th October 1862.
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 "IMPROVED
APPARATUS FOR EXTRACTING CONDENSED STEAM," communicated to me from
abroad by Gabriel Brasseur, of No. 15, Passage, des Petites Ecuries, Paris,
France, to be as follows:-
In all steam heating apparatus, by extracting the condensed water as it forms,
the greatest possible effect is obtained from the fuel, and consequently from the
steam. The object of this Invention is to obtain this extraction by means
of the apparatus shewn in the accompanying Sheet of Drawing forming part
of this Provisional Specification, and on which Figure 1 is a front view of the
improved apparatus, Figure 2 plan of same, Figure 3 transverse section.
and Figure 4 horizontal section.

which by its rod opens the vents M and permits the escape of the water by
the pipe O.
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 17th April 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD GEDGE, of the Firm of John Gedge and Son, of No. 11, Wel-
lington Street, Strand, in the County of Middlesex, Patent Agent, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of October, in the year of our
Lord One thousand eight hundred and sixty-two, in the twenty-sixth year of
Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said William Edward Gedge, Her special licence that 1, the
said William Edward Gedge, my executors, administrators, and assigns, or
such others as I, the said William Edward Gedge, my executors, adminis-
trators, 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 "IMPROVED APPARATUS FOR EXTRACTING
CONDENSED STEAM," a communication to me from abroad by Gabriel Brasseur;
of No. 15, Passage des Petites Ecuries, Paris, France, 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 nature

page_text: 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 Sheet of Drawings
hereunto annexed and forming part of this my Specification and to the
letters of reference placed on the different diagrams drawn thereon, of which
Figure 1, represents a front view of the apparatus; Figure 2, plan of
same; Figure 3, transverse and vertical section of the said apparatus, and
Figure 4 a horizontal section taken through B of Figure 3. In all steam
heating apparatus by extracting the condensed water as it forms the
greatest possible effect is obtained from the fuel and consequently from the
steam.
The object of this Invention is to obtain this extraction by means of the
apparatus herein-after described. The condensed water saturated with steam
is conveyed, firstly by the beating pipes; secondly, by a cone (made of brass
or copper) receiving all the water produced by the condensation of the steam
which directs it, by the tube marked C' (Figures 1 and 3 of the Drawing) into
the reservoir. When the water has attained its level it causes the float A to
rise, and consequently the rod I and triangular valve F through which issues
the condensed vapour. The cock E, which is open during the course of the
steam, allows the steam to force out the air contained in the reservoir when
the apparatus is at rest. The air re-enters by an orifice made in the cast-iron
reservoir. An eliptic orifice closed by a bolted plate allows the cleansing of
the interior of the reservoir. Three feet p, serve to support the reservoir at a
convenient distance or height from the ground.
In witness whereof, I, the said William Edward Gedge, have hereunto
set my hand and seal, this Seventeenth day of April, in the year of our
Lord One thousand eight hundred and sixty-three.
W. E. GEDGE. (L.S.)
