I JOHN CHARLES BAUER of N° 11, Comerford Road, Brockley, in the county of
Kent, Engineer, do hereby declare the nature of the said invention for "IMPROVE-
MENTS IN FEEDING STEAM BOILERS AND APPARATUS THEREFOR" to be as follows:-
This invention relates to the application of hydrostatic pressure for feeding
water to steam boilers.
.
A suitable arrangement for carrying out my invention consists of a receiver
placed at a higher level than that of the water within the steam boiler to be
supplied with feed water; this receiver is connected by means of pipes provided
with valves or cocks, with the upper part of the boiler containing.steam and with
the lower part of the boiler containing water respectively. The receiver is also
connected with the ordinary water supply or with an overhead tank.
By this arrangement when both communications with the steam boiler are shut
off the supply water will enter the receiver; when however the communication
with the water supply is shut off and the communications with the steam boiler
are opened, the water from the receiver will by the hydrostatic pressure resulting
from its higher level be caused to enter the boiler, the pressure from the upper and
lower parts of the boiler being balanced.

I JOHN CHARLES BAUER of N° 11 Comerford Road, Brockley, in the county of
Kent, Engineer 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 relates to the application of hydrostatic pressure for feeding 5
water to steam boilers.
A suitable arrangement for carrying out my invention consists of a receiver
placed at a higher level than that of the water within the steam boiler to be
supplied with feed water; this receiver is connected by means of pipes provided
with valves or cocks with the upper part of the boiler containing steam and with 1
the lower part of the boiler containing water respectively. The receiver is also
connected with the ordinary water supply or with an overhead tank or otherwise.
In order to enable my invention to be fully understood I will proceed to describe
the same by reference to the accompanying drawing which represents a section
shewing a portion of a steam boiler provided with a suitable apparatus for feeding
water thereto by hydrostatic pressure according to my invention.
a, represents the steam boiler of ordinary construction and b, shews my receiver
placed at a higher level than the required level of the water in the steam boiler a;
c is the pipe connecting the receiver b, with the upper part or steam space of the
boiler a, and d, is the pipe connecting the receiver with a lower part of the boiler
containing water; e and fare the valves or cocks of the pipes c and d respectively
the said valves or cocks being advantageously provided with levers g and h, jointed
to a rod i, by operating which both the valves or cocks can be opened or closed
simultaneously; j, is a pipe connecting the lower part of the receiver b, with the
· ordinary water supply and provided with a ball inlet valve k. (or other suitable
valve); , is a float of suitable non conducting material which I provide in the
receiver b, for the purpose hereinafter described.
By this arrangement when both the cocks or valves e and f, are closed and both
the communications between the steam boiler a and the receiver b, are thereby shut
off and a partial vacuum having been formed in the receiver b, in the manner
hereinafter described the supply water will enter the said receiver under pressure
from the ordinary water supply or from a tank situated at a higher level than the
receiver; when a certain quantity of water has entered the receiver b, the valve k,
will automatically close and communication with the water supply will be thereby
shut off; if the cocks or valves e and f, be now opened steam from the boiler a,
will enter the upper part of the receiver b, and a like pressure to that in the
boiler a, will be exerted on the water in the receiver b, which pressure will be
balanced by the equal pressure communicated from the water in the boiler to that
in the receiver by means of the pipe d; the water in the receiver b, is thus under
hydrostatic pressure and will flow into the boiler by gravity; the water in the
receiver b, having run into the boiler a, the cocks or valves e, and f, are then
closed and the steam left in the receiver b, will condense and form a partial vacuumi

page_text: therein and another supply of water will be caused to enter the receiver b, through
the pipe j, ready to be fed into the boiler and so on. If the water supply be
situated at a lower level than that of the receiver b, the said vacuum produced in
the receiver would cause the water to enter the same as will be well understood;
the float 7, of non-conducting material being interposed between the surface of the
water and the steam in the receiver prevents the steam from condensing as rapidly
as it would do if it were in direct contact with the water.
It will be obvious that instead of operating the cocks or valves e and f, by
hand as herein before described I can connect them to a suitable arrangement of
apparatus for automatically operating them when the water in the boiler reaches &
certain level.
•
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. The method herein described of feeding water to steam boilers by utilizing
the hydrostatic pressure of the feed water in the manner substantially as herein-
before described.
2. In an apparatus for feeding water to steam boilers by hydrostatic pressure
the use of a steam tight receiver connected with the boiler and with the water
supply substantially as hereinbefore described and represented in the accompanying
drawing.
3. The improved apparatus for feeding water to steam boilers herein before
described and illustrated in the accompanying drawing.
