PROVISIONAL SPECIFICATION.
An Improved Method of Returning Condensation Water to the
Generating Boiler.
I SAMUEL FYFE EASTON of 2 Copthall Buildings, Moorgate Street, in the City
of London, Gentleman, do hereby declare the nature of this invention to be as
follows:-
:-
This invention has for its object to provide an improved method of returning
condensation water from steam pipes, coils, cylinder jackets, and the 'like to the
generating boiler; and consists essentially in separating or collecting the con-
densation water and in forcing the same back to the generating boiler by means of
an injector.
In carrying out this invention, according to one arrangement, the main steam
pipe from the boiler leads to a separator and from the separator to the engines or
machines to be fed with live steam and drains into the separator. Below or in the
bottom of the separator is an injector of suitable construction so arranged that the
condensation water can flow to the water cone. The injector is supplied with live
steam from the separator or direct from the boiler and is provided with a discharge
pipe leading to the water space of the boiler and through which the condensation
water is returned.

COMPLETE SPECIFICATION.
An Improved Method of Returning Condensation Water to the
Generating Boiler.
I SAMUEL FYFE EASTON late of 2 Copthall Buildings, Moorgate Street, in the
City of London but now of Grove House, Harrogate, in the County of York,
Gentleman, do hereby declare the nature of this 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 has for its object to provide an improved method of returning
condensation water from steam pipes, coils, cylinder jackets, and the like to the
generating boiler; and consists essentially in separating or collecting the con-
densation water and in forcing the same back to the generating boiler by means of
a condenser and injector.
In carrying out this invention, according to one arrangement, the main steam pipe
from the boiler leads to a separator and from the separator to the engines or
machines to be fed with live steam and drains into the separator and thence into a
condenser. Below or in the bottom of the condenser is an injecter of suitable
construction so arranged that the condensation water can flow to the water cone.
The injector is supplied with live steam from the steam pipe or direct from the
boiler and is provided with a discharge pipe leading to the water space of the boiler
and through which the condensation water is returned.
In the accompanying sheet of drawings,
Fig. 1 is a diagrammic view showing the method of returning to the boiler the
water condensed in a pipe supplying steam from the boiler to a steam engine and te
a steam hammer and the water condensed in the cylinder jacket of the engine.

page_text: Fig. 2 is a similar view showing the method of returning the water condensed in
a steam heating pipe jacket or coil to the boiler supplying the steam.
Fig. 3 is a detail view showing the arrangement of the condenser and injector.
The boiler 1 supplies in Fig. I the steam engine 2 and steam hammer 3 by means
of the pipe 4 which is so inclined to the horizontal that all condensation water drains
into the separators 5, 6 and thence to the condensers 7 and 8 and the jacket of the
engine cylinder also drains by gravity to the condenser 10. The bottoms of the
condensers 7, 8, 10 are connected as shown in detail in Fig. 3 to the water cones of
the injectors 11, 12, 13 respectively by the pipes 14, 15, 16 and the steam cones of
the injectors are connected by pipes 17, 18, 19 to the supply pipe 4 and the discharge
nozzles to the water space of the boiler by the pipes 20, 21, 22 and cocks and check
valves 23, 24, 25.
The condensation water drains into the condensers and from thence it passes by
gravity to the water cones of the injector. Cocks 26, 27, 28 regulate the flow to
the injectors and are so adjusted that a small quantity of water is always retained
in the condensers. Cocks 29, 30, 31 regulate the supply of steam. The condensers
are provided with water gauges 32 to indicate the amount of condensation water
contained therein.
In Fig. 2 the steam pipe 4 and coil 33 drain into a condenser 34 connected through
a pipe 35 and the cock 36 to the water cone of the injector 37 whose steam cone is
supplied with steam through the cock 38 and pipe 39. The discharge nozzle from
the injector is connected by the pipe 40 and cock 41 to the water space of the
boiler 1.
The condenser 34 may be fitted with a coil 42 as shown in dotted lines so that
the cold auxiliary feed water may pass through from the feed pump and condense
the live steam which would impart a portion of its heat to the feed water. This
may also be done with an external water jacket or series of pipes.
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 :-
:-
1. Collecting the condensation water by gravity in a condenser and feeding the
said water by gravity and under pressure to the water cone of an injector which
forces it back to the generating boiler substantially as described.
2. The arrangement of apparatus for returning condensation water to the generating
boiler and for heating feed water substantially as described with reference to the
drawings.
