PROVISIONAL SPECIFICATION.
Improved Means for Feeding and Heating Water for Steam
Boilers.
I, WILLIAM KEEN of Regency Works White Hart Street, Kennington,
London, Engineer do hereby declare the nature of this invention to be as
follows:-
My improved boiler feeder consists of two chambers with valve face dividing
the two. One of these chambers is connected to the boiler and is open to the
steam and water space of boiler. A slide valve works in this chamber, and is kept
working while the boiler is in use by means of a strap from nearest engine shaft or
pulley, or by some other well known mechanical device, or by a steam cylinder
fitted to feeder.
This valve is so arranged that when it is at bottom or end of travel, the
communication existing between the chambers is cut off and that between the
supply tank and chamber is opened, and consequently water will flow in. When
the valve is at top, communication is opened between the two chambers and
closed against water in supply tank. The water then finds its level by gravity in
the two chambers.
If the boiler is using water to full capacity of feeder, the first chamber is filled
at every stroke, but if the chamber is not emptied only so much water as will fill
it will be admitted. Thus it cannot overfill the boiler.
If the valve is kept in motion no further attention is required. No force is
needed to drive the water into the boiler, nor can water be wasted.
simple in construction there being only one moving part in it.
to make.
The feeder is
It is also inexpensive
No steam can be wasted by it, as what steam is condensed returns to the boiler
with the feed water, and thus the feed water is heated before entering the
boiler.

Improved Means for Feeding and Heating Water for Steam
Boilers.
L, WILLIAM KEEN of Regency Works White Hart Street, Kennington,
London, 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 is designed to supply an automatic feeder for boilers which shall
act by gravitation and thus require little supervision. Its contiguity to the boiler
enables the water to be partially heated before entering the boiler.

page_text: My improved boiler feeder consists of two chambers with valve face dividing the
two. One of these chambers is connected to the boiler and is open to the steain
and interspace of boiler but separable by stop cock when necessary. A vertical
slide valve works in this chamber and is kept working while the boiler is in use by
means of a strap from nearest engine shaft or pulley or by some other well known
mechanical device, or by a steam cylinder fitted to feeder.
This valve is so arranged that when it is at the bottom or end of travel, the
communication existing between the chambers is cut off and that between
the supply tank and one of the chambers is opened, and consequently water will
flow in.
When the valve is at top, communication is opened between the two chambers
and closed against water in supply tank. The water then finds its level by
gravity in the two chambers. If the boiler is using water to full capacity of
feeder, the first chamber is filled at every stroke, but if the chamber is not
emptied only so much water as will fill it will be admitted. Thus it cannot
overfill the boiler.
I will now describe my invention with reference to the accompanying drawings
in which
Fig. 1 shows a sectional elevation of my improved boiler-feeder.
Fig. 2 is a sectional plan view of the same.
Fig. 3 is a side elevation of the ports for admitting water.
44, is the spindle of slide valve.
b, is the valve with double ports b', b².
c, is the exterior wall of feeder.
c, c, c, c, are ports. d, is the outer chamber which receives the water from
the tank. e, is the inner chamber which communicates with the boiler. f, is a
pipe in which water is received prior to its entering the feeder. g, is a pipe which
may be employed for conveying air or waste steam to tank. h, is a gland aud
stuffing box. i, is a casing forming part of the second chamber, and also enclosing
the ports. j, j, are set screws. I, is a pipe admitting steam to the feeder to
equalize the pressure. m, is the water supply pipe to boiler. The arrows show
the direction of the water.
If the valve is kept in motion no further attention is required. No force is
needed to drive the water into the boiler as the tank would be placed above the
boiler, nor can water be wasted.
The feeder is simple in construction there being only one moving part in it. It
is also inexpensive to make.
No steam can be wasted by it, as what steam is condensed returns to the boiler
with the feed water and thus the feed water is heated before entering the
boiler.
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 :-
In a boiler feeder and heater the arrangement and combination of chambers,
slide valve, ports and pipes ensuring an automatic supply of heated water by
gravitation, as herein described and set forth.
