Gedge and Son, of No. 11, Wellington Street, Strand, in the
County of Middlesex, Patent Agent, for the Invention of "IMPROVE-
MENTS IN THE METHOD OF AND APPARATUS FOR FEEDING STEAM BOLLERS.".

France.
PROVISIONAL SPECIFICATION left by the said William Edward Gedge
at the Office of the Commissioners of Patents, with his Petition, on
the 24th July 1868.
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 "IMPROVE-
MENTS IN THE METHOD OF AND APPARATUS FOR FEEDING STEAM BOILERS," a
communication to me from abroad by Emile Adolphe Tyrode and Pierre

to be as follows:-
This Invention consists in a method of feeding steam boilers which
permits the application of the steam to a great number of novel uses,
such as ridding trees of caterpillars, lie washing, the destruction of the
"pyrale" in vines, and in all small workshops where manual labour-is
still applied as a motor.
The cylindrical and vertical boiler is traversed in the centre by the
"chimney from the fire-place; it is provided with all the accessaries, such

jets of steam a pipe with cock is fitted a little below the usual water
level, and to this pipe is fitted an india-rubber tube furnished interiorly
with a spiral of iron wire, this tube terminating according to its
-destined use in an appropriate watering rose.
On the accompanying Sheet of Drawing forming part of this
Provisional Specification it will be seen that the boiler is surmounted
by a reservoir M raised upon three or four Tirons; this reservoir
is put in communication with the boiler by two tubes A and B.
The first tube A furnished with a cock starts in the steam space
-and goes to the upper part of the reservoir; the second B also possesses
a cock, and starting from the lower part of the reservoir descends to
about the middle of the boiler. A valve opening in descending is placed

valve might be dispensed with, the cock sufficing; but this cock would
complicate the working of the apparatus and require more attention
from the operator, whereas the valve acts mechanically, as herein-after
explained. T indicates a stop intended to prevent the valve from closing
the tube B. Lastly, a funnel furnished with a cock C serves for the
introduction of water into the reservoir. To use this boiler it is first
filled by the funnel C and tube B, and when it has received a suitable
quantity of water the cocks B and A are closed, and water is still
poured into the reservoir until it attains the level X, Y, which is
ascertained by means of the cock placed at Y, which permits the water
to run off when it has attained this level; this done, all the taps
are closed and the heating begins. Steam forms rapidly in the boiler,
and having attained the desired pressure continues thus until the

the boiler without undergoing a very appreciable condensation, as the
water in this reservoir is raised to a certain temperature by the method
of heating. The pressure being equal at X, Y, and at B, the liquid
no longer obeying but the laws of gravity causes the valve B to
lower, and penetrates into the boiler. When the tap A is closed,
without regard to the tap B, which remains open, the pressure of
itself closes the valve, and the tube B is thus mechanically closed.
As the reservoir M is so constructed that its volume of water is double
that required for one feeding, when this feeding is completed there still
remains water which absorbs the heat of the steam and the steam itself
abandoned in the reservoir.
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 21st January 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, 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,
send greeting..

page_text: and Pierre Théophile Cousty, both of 39, Faubourg St. Martin, 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 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
Sheet of Drawing forming part of this Specification, and to the figures
and letters of reference marked thereon:-
This Invention consists in a method of feeding steam boilers which
permits the application of the steam to a great number of novel uses,
such as ridding trees of eaterpillars, lie washing, the destruction of the
"pyrale" on vines, and in all small workshops where manual labour
is still applied as a motor with regular movements.

sufficing; but this cock would complicate the working of the apparatus
and require more attention from the operator, whereas the valve acts
mechanically, as herein-after explained. T (Figs. 1 and 2) indicates a
stop intended to prevent the valve from closing the tube B. Lastly, a
funnel furnished with a cock C serves for the introduction of water into
the reservoir. To use this boiler it is first filled by the funnel C and
tube B, and when it has received a suitable quantity of water the cocks
B and A are closed, and water is still poured into the reservoir until
it attains the level X, Y, this being ascertained by means of the cock
placed at Y, which permits the water to run off when it has attained
such level; this done, all the taps are closed and the heating begins.
The steam forms rapidly in the boiler, and having attained the desired
pressure continues thus until the water guage gives warning that feeding
is necessary; the cocks B and A are then opened, and the steam
passing to the upper part of the reservoir M soon attains at this point
the same pressure as in the boiler without undergoing a very appreciable
condensation, as the water in this reservoir is raised to a certain
temperature by the method of heating. The pressure being equal at
X, Y, and at B, the liquid obeying the laws of gravity causes the valve B
to lower and penetrate into the boiler. When the tap A is closed, no
heed being taken of the tap B which remains open, the pressure of itself
shuts the valve, and the tube B is thus mechanically closed. As the
reservoir M is so constructed that its volume of water is double that
required for one feeding, when this feeding is completed there still
remains water which absorbs the heat of the steam, and the steam itself
abandoned in the reservoir, and thus the steam employed in the feeding
is further utilized.
In witness whereof, I, the said William Edward Gedge, have herc-
unto set my hand and seal, this Twenty-first day of January, in
the year of our Lord One thousand eight hundred and sixty-
nine.
