PROVISIONAL SPECIFICATION.
Improvements in Feed Water Heaters and Purifiers for Steam
Boilers and the like.
We, RICHARD WITHINGTON BROMILEY SANDERSON, of the South Corridor,
Royal Exchange, Manchester, in the County of Lancaster, Cotton Merchant, and
JOHN CHAPMAN, of 32 Gate Street, Swinton, near Manchester aforesaid, Engineer,
do hereby declare the nature of this invention to be as follows:-
Our present invention relates to improvements in feed waters and purifiers for
steam boilers and the like and consists partly in improvements on the feed water
heater and purifier for which Letters Patent No. 4342 and dated March 21st 1888
were granted to me the said Richard Withington Bromiley Sanderson.
According to our improvements the feed water is delivered through a horizontal
feed pipe preferably to the bottom of a socket pipe with three branches placed
vertically in the steam space of the boiler; we place at the top of each branch a
disc or saucer with a turned up flange within which are a series of radial_or
other division pieces dividing the space between the mouth of the feed pipe
and the outer flange of the disc so that the feed water from the feed pipe
passes up each branch pipe into its disc where it is divided by the radial or other
divisions and falls over the outer flange into the steam space of the boiler. We
may use one socket only or two or more sockets and branches in each boiler.
That part of our invention which relates to improvements on the Patent
No. 4342 of 1888 consists in the application of an open cap to the top of the feed
pipe, sufficient space being left between the top of the pipe and the cap to allow
the feed water to pass freely on to the top plate of the series of discs or plates
arranged in cone form and supported by the vertical feed pipe over the edges of
which plates or through perforations in which the water escapes into the steam
space of the boiler.

Improvements in Feed Water Heaters and Purifiers for Steam
Boilers and the like.
We, RICHARD WITHINGTON BROMILEY SANDERSON, of the South Corridor,
Royal Exchange, Manchester, in the County of Lancaster, Cotton Merchant, and
JOHN CHAPMAN, of 32 Gate Street, Swinton, near Manchester aforesaid,
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 :-
Our present invention relates to improvements in feed water heaters and purifiers
for steam boilers and the like and consists partly in improvements on the feed water
heater and purifier for which Letters Patent No. 4342 and dated March 21st 1888
were granted to me the said Richard Withington Bromiley Sanderson.
According to our improvements the feed water is delivered through a horizontal

page_text: feed pipe preferably to the bottom of a socket pipe with three branches placed
vertically in the steam space of the boiler; we place at the top of each branch
a disc or saucer with a turned up flange within which are a series of radial
or other division pieces dividing the space between the mouth of the feed pipe
and the outer flange of the disc so that the feed water from the feed pipe passes up
each branch pipe into its disc where it is divided by the radial or other divisions and
falls over the outer flange into the steam space of the boiler. We may use one
socket only or two or more sockets and branches in each boiler.
That part of our invention which relates to improvements on the Patent
No. 4342 of 1888 consists in the application of an open cap to the top of the feed
pipe sufficient space being left between the top of the pipe and the cap to allow
the feed water to pass freely on to the top plate of the series of discs or plates
arranged in cone form and supported by the vertical feed pipe over the edges of
which plates or through perforations in which the water, escapes into the steam
space of the boiler.
And in order that our invention may be fully understood and readily carried into
effect we will describe the accompanying sheet of drawings reference being had to
the figures and letters marked thereon.
Fig. 1 is a side elevation of our improved feed water heater and purifier.
Fig. 2 is a plan view of part of the same, and Fig. 3 is a sectional elevation
of Fig. 2.
Fig. 4 is a sectional side elevation of part of a steam boiler illustrating another
part of our invention.
In Fig. 1, a represents part of the horizontal pipe through which the feed
water is conducted to the feed water heater through a socket pipe b, to which is
bolted a pipe c with three branches; at the top of each branch pipe is secured one
of our improved feed water heaters each of which consists of a disc or saucer d with
radial or other divisions e, shown more clearly in Figs. 2 and 3. The feed water
passes from the branch pipes into the saucers d where it is divided by the
divisions e as it flows to the outer flange over which it passes and falls gently over
into the steam space of the boiler.
In order that the feed water may be thoroughly heated we prefer to place
the saucers very near to the top of the boiler so that the feed water falls
through almost the whole steam space before it meets with the body of water in
the boiler.
In place of dividing the branch pipe c into three branches there may be fewer or
more branches; when two branch pipes are employed the arrangement is well
adapted to suit the front end of boilers in which a gusset stay is employed.
One, two, or more socket and branch pipes with discs or saucers are employed in
each boiler according to the size or requirements of the boiler.
In Fig. 4 the feed water heater described in Patent No. 4342 of 1888 is
illustrated.
In this view,―g represents part of the shell of a boiler, h the pipe through which
the feed water enters the feed water heater i mounted on a branch pipe j.
According to our present invention we attach an open cap k to the top of the
branch pipe or to the top of the feed water heater i sufficient space being
left between the top of the pipe j and the cap k to allow the feed water to pass
freely on to the top plate of the series of discs or plates which forms the feed water
heater i.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. A feed water heater consisting of branch pipes connected to the feed pipe and
provided with discs or saucers arranged to discharge the feed water into the steam
space of a boiler substantially as described and as illustrated in Figs. 1, 2 and 3 of
the accompanying drawings.

page_text: 2. The use and application of the cap k to the feed water heater described
substantially as and for the purposes described.
