PROVISIONAL SPECIFICATION.
Improvements in Feed Water Heaters and Purifiers.
We, RICHARD WITHINGTON BROMILEY SANDERSON, of Office D, Royal
Exchange, Manchester, in the County of Lancaster, Cotton Merchant, and
JOHN CHAPMAN, 32 Gate Street, Swinton in the said County Engineer do hereby
declare the nature of this invention to be as follows:
Our present invention consists in certain improvements on the feed water heater
and purifier for which Letters Patent numbered 4342 and dated March 21st 1888
were granted to the said Richard Withington Bromiley Sanderson.
According to our improvements the feed water is delivered preferably to the
bottom of a tube or vessel, placed vertically in the steam space of a boiler, from
the top of which it escapes and flows over projecting perforated discs or receivers
which form a conical series of ledges. Each disc or receiver is perforated and
preferably dished so that the greater part of the feed water issuing from the
central tube or vessel passes downward through the perforations in the discs, instead
of all flowing over the ledges as in the former invention.
We prefer to make each perforated disc or receiver in say two parts for
convenience in putting the same into the boiler.
Deted this 10th day of February 1893.

COMPLETE SPECIFICATION.
Improvements in Feed Water Heaters and Purifiers.
We, RICHARD WITHINGTON BROMILEY SANDERSON, of Office D, Royal
Exchange, Manchester, in the County of Lancaster, Cotton Merchant, and
JOHN CHAPMAN, of 32 Gate Street, Swinton, in the said County, 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 consists in certain improvements on the feed water heater
and purifier for which Letters Patent numbered 4342 and dated March 21st 1888
were granted to me the said Richard Withingtou Bromiley Sanderson.
According to our improvements the feed water delivered preferably to the
bottom of a tube or vessel, placed vertically in the steam space of a boiler, from the
top of which it escapes and flows over projecting perforated discs or receivers which
form a conical series of ledges. Each disc or receiver is perforated and pre-
ferably dished so that the greater part of the feed water issuing from the central
tube or vessel passes downward through the perforations in the discs instead of all
flowing over the ledges as in the said former invention.
We prefer to make each perforated disc or receiver in say two parts for
convenience in putting the same into the boiler.
And in order that our invention may be fully understood and readily carried into
effect we will describe the accompanying two Sheets of drawings reference being
had to the figures and letters marked thereon.
Figure 1 is a longitudinal section of a boiler showing two of the improved feed
water heaters and purifiers in position.

page_text: Fig. 2 is a cross section of the boiler and
Figs. 3 to 11 are detail views of the discs which form the conical series of openwork
trays.
In the steam space of the boiler A are placed vertically two of the improved
feed water heaters and purifiers B which are supplied with water by the feed pipe C.
Each purifier B is composed of a series of discs d, e, f, illustrated by the detail
views, Figs. 3 to 11, in which Figs. 3 to 8 illustrate a series of discs partly solid
and partly grating or openwork, and Figs. 9, 10, 11 illustrate a series of perforated
dises the larger discs e and fin each case being made in two pieces for convenience
in introducing the same to the boiler.
The water issuing from the top of the central tube of each purifier B flows
through the grating or perforatious as the case may be of the top disc d and falls
on to the solid portion of the second disc e whence it flows through the surrounding
grating or perforations and on to the solid portion of the bottom disc f escaping
thence through the surrounding grating or perforations into the boiler.
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 :-
The improved feed water heater and purifier composed of a conical series of
openwork or perforated discs substantially as herein described and illustrated.
Dated this 10th day of November 1893.
