Sir EDWARD GREEN, Baronet, of the firm, Edward Green and Son, Wakefield,
Yorkshire, Fuel Economizer Manufacturer do hereby declare the nature of my
said invention to be as follows:-
The object of this invention is, to construct the lower chambers of fuel economizers
in a novel manner.
According to my invention the bottom of the bottom chambers is horizontally level
and may be fed from the front or from the back by a horizontal feed, or by one of
the methods referred to in my previous patent No. 8178 of the year 1885.
If the feed be at the back, that end of the lower chamber may be of curved shape
looking upwards, and if the feed be at the front, that end of bottom chamber may be
of curved shape looking downwards, or vice versa, and this latter shape may be adapted
with any kind of back feed.
A cleansing appliance for the bottom chamber may have a to and fro motion, or it
may be arranged for turning; and the aperture, through which the cleansing tool can
be inserted may be covered by an access lid or plate affixable thereto.
The lower chamber may be of circular, oval or other shape.

page_text: A Novel Construction of Bottom Chamber for Fuel Economizers.
I, Sir EDWARD GREEN Baronet, of the firm Edward Green and Son, Wakefield,
Yorkshire, Fuel Economizer Manufacturer 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 a certain novel construction or arrangement of the bottom
boxes or chambers of fuel economizers and consists in making the bottom pipes below
where the vertical pipes are arranged, horizontal or nearly horizontal, for the deposit
of impurities from the water, the ends of the said bottom boxes may be curved or
inclined downwards to lead into a receptacle, into which the deposit can be scraped by
a scraper or moved to that end by a creeper tool. The opposite end of said pipe may
also have a curved or inclined end for the feed or the back end may be stopped for
feeding by one of the vertical pipe whether said pipe be one of the series or as a
separate pipe as referred to in my previous Patent No. 8178 of 1885, or the front of
the lower chamber or box may have the feed connected to it.
Each bottom box or chamber of all the series or stack of piping may have their
connections with a curved or inclined chamber for the collection of sediment; a flush
or mud tap being provided for cleaning out the bottom receptacle.
I prefer each bottom box, (whether acting singly or in combination with others and
a bottom collecting pipe common to all the series) to have the scraper or cleaning tool
permanently fitted therein, so that by a to and fro motion, or a circular motion the
deposit collected in the bottom boxes or chambers can be gathered from time to time
into the receptacle or sludge pipe, so that a free passage for water through all the
pipes is obtained with facility, but said bottom boxes may be fitted with what are
known as access lids which when removed, permits of the scraper tool being inserted
into the bottom box through the uncovered aperture.
My invention will be understood by reference to the annexed drawings, in which at
Figure 1 show five pipes A, A, of a fuel economizer attached or socketed to a bottom
pipe B, the front end of which is curved at C and has connected to it a sludge pipe D
into which the sediment or deposit from the bottom box B can be drawn by rotating
the tool E by means of the outside handle F the stem or rod G of said scraping tool
passing through a flanged cap or end cover H as a guide, so that said tool E may not
only be rotated but drawn to and fro. The back end of the bottom box B in this
Figure has a curved up back end I with a feed pipe J attached, so that water passing
through the same may fill the lower box or chamber B and rise up all the pipes A, A,
of the series in a well known manner for heating as feed water or otherwise; but by
stopping off the bottom box B at the dotted lines K the back end pipe of the series
may be the feed water pipe.
Figure 2 represents a modification of the foregoing bottom box or chamber B with
the front curved end or neck C provided with an access lid L, through which the
scraping tool E can be guided when drawn to and fro by its handle F. The feed water

page_text: pipe J in this arrangement is horizontally arranged but out of the axial line of the
bottom box or chamber B by the bend I.
The bottom box or chamber B can be made of any shape, an example of which I
show at Figure 3 where the front end of the box or chamber is of curved form as
at M, the outer end being provided with a plate and saddle piece N for closing the end
if a tool is not permanently fitted therein, but said end may be provided with a flange
as at H Figure 1 or with an access lid as at L. Figure 2.
The lower surface of the bottom box or chamber B, below the economizer tubes A,
is horizontal and with the front end which is outside the brickwork P curved at the
under side and provided with a flange for the reception of neck pieces C which connect
all the horizontal bottom boxes or chambers of the economizer to a curved or angled
pipe D as a receptacle for the sediment scraped from the lower boxes B, so that said
sediment or sludge can be blown or allowed to run out with a flush of water by the
pipe when the flush valve R is opened.
The sediment receiving pipe D may serve as a feed pipe to the economizer tubes as
at Figure 4 when the feed valve I is opened but this arrangement of the feed valve I
is not necessary because any of the previously described methods of feeding can be
adopted if desired, the outlet for the deposit or sediment being in every case in front
of or outside the brickwork within which the fuel economizer is built. S is the
soot pit.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
The construction of the lower chambers "of fuel economizers" having a horizontal
base with drooping or curved ends or necks leading to the outside or front of the
brick work to mud receivers, whether the feed be at the back as at Figure 1, or
Figure 2, or from the front as at Figure 4, or by utilizing one of the pipes of the
economizer as a feed pipe as referred to in my former Patent and as hereinbefore
described and substantially as shown in the annexed drawings.
The 23rd day of November 1887.
