or impurities thererтош.
We, CHARLES JOHN GALLOWAY and JOHN HENRY BECKWITH both of Knott Mill
Iron Works Manchester in the County of Lancaster, Engineers, do hereby declare the
nature of this invention to be as follows:-
Our invention relates to apparatus connected to a steam boiler, for the purpose.
of heating the feed water on its way to the boiler and effecting deposit of
impurities from the water, instead of allowing them to pass with the water into
the boiler and become deposited therein. We provide a vessel which communicates
with the boiler by two passages, the one opening into the steam space and the other
into the water. These passages ascend some height within the vessel, the steam
passage having lateral openings under a crown which covers the pipe, and the water
passage having also an opening into an annular space enclosed by an outer pipe which
descends some distance towards the bottom of the vessel: At the top of the vessel
there is a distributing nozzle by which the feed water enters the vessel. At the
bottom of the vessel there may be a blow off pipe which can be opened to clear out
mud and deposit, and at the top or side of the vessel there is a man hole to give access
to the interior.
The vessel being put in communication with the boiler the blow off being closed,
and feed water being supplied to the distributing nozzle, the action is as follows. The
water entering in subdivided streams is heated by the steam in the vessel, which as it
is in part condensed receives fresh supply from the boiler; when the water in the
vessel rises to the level of the opening into the water pipe, it flows by siphon action
into the boiler, but most of the impurities are deposited in the lower part of the vessel
and can from time to time be blown out or otherwise removed.

We, CHARLES JOHN GALLOWAY and JOHN HENRY BECKWITH both of Knott Mill
Iron Works, Manchester in the County of Lancaster Engineers 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 :-
Our invention relates to apparatus connected to a steam boiler, for the purpose of
heating the feed water on its way to the boiler and effecting deposit of impurities
from the water, instead of allowing them to pass with the water into the boiler
and become deposited therein. For this purpose we arrange the apparatus as shewn
in section by the accompanying drawing. A is a vessel which communicates with
the boiler by two passages, the one B opening into the steam space and the other C
extending down into the water. These passages ascend some height within the
vessel A the steam passage B having lateral openings under a crown D which covers
the pipe, and the water passage C having also communication E with an annular
space enclosed by an outer pipe F which descends some distance towards the bottom
of the vessel A. At the top of the vessel there is a distributing nozzle G, or it might
be a perforated pipe, by which the feed water enters the vessel A. At the bottom of
the vessel there may be a blow off pipe H which can be opened from time to time to
clear out mud and deposit, and at the top or side of the vessel there is a manhole K
to give access to the interior.
The vessel being put in communication with the boiler, the blow off H being closed,
and feed water being supplied to the distributing nozzle G, the action is as indicated
by the arrows, that is to say, the water entering in subdivided streams from G is
heated by the steam in the vessel which as it is in part condensed receives fresh
supply from the boiler, when the water in the vessel rises to the level of the opening E,
it flows by siphon action up the annular passage within F and down C into the boiler,
but most of the impurities are deposited in the lower part of the vessel A, and can from
time to time be blown out or otherwise removed.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed, we declare that what we claim is :—
For heating feed water for boilers and effecting deposit of impurities therefrom, the
construction and use of apparatus substantially as described with reference to the
accompanying drawing.
