PROVISIONAL SPECIFICATION.
Improvements relating to the Circulation of Water in Surface
Condensers.
I ELOI GUIGON of Lyons in the Republic of France Engineer do hereby
declare the nature of this invention to be as follows:-
:―
This invention relates to the circulation or feed of water in surface condensers
used in marine and other engineering.
Heretofore the water has generally been caused to circulate in said condensers
by being pumped therein by a centrifugal or other pump usually a centrifugal
pump driven by belting from a main shaft or subsidiary engine and being allowed
to flow out by an outflow pipe.
This invention consists in arranging a steam ejector in connection with the con-
denser and fitting same with a steam supply pipe with valves etc. for regulation and
with a suction pipe from the condenser. The condenser is then provided with an
inlet pipe for supply of water thereto said inlet pipe having a suitable cock therein.
The ejector will then draw the water from the condenser the latter filling naturally
by the inlet pipe.

COMPLETE SPECIFICATION.
Improvements relating to the Circulation of Water in Surface
Condensers.
1, ELOI GUIGON, of Lyons, in the Republic of France, Engineer, do hereby
declare the nature of my invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:-
This invention relates to the circulation or feed of water in surface condensers
used in marine and other engineering.
Heretofore the water has generally been caused to circulate in said condensers
by being pumped therein by a centrifugal or other pump usually a centrifugal
pump driven by belting from a main shaft or a subsidiary engine and being allowed
to flow out by an outflow pipe.
This invention consists in arranging a steam ejector in connection with the con-
denser and fitting same with a steam supply pipe with valves etc., for regulation
and with a suction pipe from the condenser. The condenser is then provided with
an inlet pipe for supply of water thereto, said inlet pipe having a suitable cock
therein. The ejector will then draw the water from the condenser the latter filling
naturally by the inlet pipe.
The accompanying drawings represent the system herein-described as applied to
the engines of a dredger of 20 horse-power, A is the exhaust pipe from the engine
to the condenser, B suction pipe of the air pump I. C delivery pipe of said air
pump. D suction pipe of the circulating pump H. E delivery pipe of the
circulating pump H. F steam feed pipe to the ejector G. J discharge pipe for
the condenser. K inlet water pipe to the condenser. The centrifugal pump with
its pipes and accessories being dispensed with is replaced by the inlet pipe K with
regulating cock therein.
The pipe F is provided with a cock by which the steam may be regulated until
sufficient exactly to perform the work required.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
The combination with a surface condenser of a steam ejector G adapted to cause
the circulation of condensing water in said condenser in place of a feed pump thereto
substantially as herein set forth.
