Complete Specification Left, 12th Apr., 1890-Accepted, 17th May, 1890
PROVISIONAL SPECIFICATION.
Apparatus for Purifying Water for Economisers.
We, GEORGE WALLIS ALLEN, of 63 York Chambers, 27 Brazenose Street, Man-
chester in the County of Lancaster, Gentleman, and HENRY JOHN ALFRED BOWERS,
of the same place, Engineer, do hereby declare the nature of this invention to be as
follows:-
In the Specification to Letters Patent No. 7772 A.D. 1887 granted to us we describe
the use of apparatus for purifying the feed water for boilers. This apparatus consists
of an open trough and scumplate placed within the boiler and a separator placed
outside the boiler.
Our present invention consists chiefly in certain novel arrangements and adaptations
of such apparatus with the object of applying the same advantageously to an
economiser.
In carrying our invention into effect we dispense with the aforesaid scumplate and
substitute therefor a number of vessels which we term collectors and which are placed
in the bottom boxes of the economiser to collect the impurities deposited by the feed
water. Each collector is preferably a slotted casting of an inverted V shape in cross
section but any other suitable form may be employed. To each collector a flow pipe
is connected which passes upward through one of the tubes of the economiser and
these flow pipes are united in a receiver (or receivers) which is connected to a
separator (or separators). The return pipe from the separator is connected to the
bottom boxes of the economiser and terminates in a nozzle on the injector principle in
order to insure the circulation of water in the proper direction.

Apparatus for Purifying Water for Economisers.
We, GEORGE WALLIS ALLEN, of 63 York Chambers, 27 Brazenose Street, Man-
chester, in the County of Lancaster, Gentleman, and HENRY JOHN ALFRED BOWERS,
of the same place, Engineer, do hereby declare the nature of this said invention and
in what mannor the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
In the Specification to Letters Patent No. 7772 A.D. 1887 granted to us we describe
the use of apparatus for purifying the feed water for boilers. This apparatus consists
of an open trough and scumplate placed within the boiler and a separator placed
outside the boiler.
Our present invention consists chiefly in certain novel arrangements and adaptations
of such apparatus with the object of applying the same advantageously to an
economiser.
In carrying our invention into effect we dispense with the aforesaid scumplate and
substitute therefor a number of vessels which we term collectors and which are placed
in the bottom boxes of the economiser to collect the impurities deposited by the feed
water. Each collector is preferably a slotted casting of an inverted V shape in cross
section but any other suitable form may be employed. To each collector a flow pipe
is connected which passes upward through one of the tubes of the economiser and
these flow pipes are united in a receiver (or receivers) which is connected to a
separator (or separators). The return pipe from the separator is connected to the
bottom boxes of the economiser and terminates in a nozzle on the injector principle in
order to insure the circulation of water in the proper direction.

page_text: 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, markod, thereon.
Figure 1 is an end and Fig. 2 a side elevation, both partly in section and, Fig. 3 is
a plan illustrating the 'application of our invention to an economiser.
In these views the economiser tubes are designated a and the bottom boxes ; the
slotted castings.or..collectors caro.placed within the bottom-boxes b and each
collector c is connected by a flow pipe d. to. one of the two, receivers or junction
boxes e which in turn are connected by the pipes to the separator.g; the pipe f being
controlled by the valves h. The return pipe, from the separator which is controlled
by a valve is connected to the bottom boxes b.
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. In an economiser the arrangement use and application of the collectors c or their
equivalents placed in the bottom boxes and communicating by means of the flow
pipes for their equivalents with an external separator.
2. The combination with the separator g, of the collectors c placed in the bottom
boxes ond connected by flow and return pipes to said separator substantially as herein
shown and described.
