page_text: I, SIR EDWARD GREEN, Baronet, of the Firm, E. Green and Son, Limited,
Wakefield, Yorkshire, Fuel Economizer Manufacturer, do hereby declare the
nature of this invention to be as follows:-
-:
This invention relates to certain constructive features and to arrangement of
parts of apparatus employed for the heating of water or air, and is specially for
use in what are known as fuel economizers i.e. apparatus fitted in flueways of
furnaces and consisting of a series of pipes and end boxes, through which feed
water passes and becomes heated by the waste heat and gases on their way to a
chimney. The valve tubes may be whole or in halves to be bolted together
lengthwise.
In order to carry my invention into practice, I construct the inlet, and in most
cases the outlet tube or tubes also, with internal ribs or fillets either in the casting
or by fitting and securing them in place for valves or diaphragms on a screw
threaded rod capable of being operated by outside handle or hand wheel in order
to open the whole of the valves for a free supply to all the heating tubes which are
generally arranged in series or nests by top and bottom or end boxes, or to shut
certain of the valves against or into the fillets and so cause the water or air to pass
down or up one or more of the tubes, and up or down one or more of the other
tubes, either of the same or of the adjoining series.
This shutting off of certain tubes or series or rows of tubes by the valves or
diaphragms will enable any one, or more series, or rows to be blown off with a
full blast pressure, each series or rows being provided with blow off taps which can
be opened singly or in any desired number.
The fillets and valves can be centrally arranged or they may be out of the centre
in which case the floor of the tube or tubes would serve as supports and guides to
the movements of the valves, the ends of said tubes having glands and packings
to keep the valve rods water and air tight.
Some of the end boxes, or one or more of the tubes of one series or rows can be
in connection with the next, for instance, I can feed down one pipe of a row and
then up through three pipes into top box, then by a bend, or elbow, or other con-
nection, I can feed down one pipe of the next row, and up three to the bend of
the next, and so on, or up and down two in succession.

. I, SIR EDWARD GREEN, Baronet, of the Firm, E. Green and Son, Limited,
Wakefield, Yorkshire, Fuel Economiser 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 has for object, arranging valves within the boxes or entry and
exit pipes of a fuel economiser in such manner that all the tubes may be simul-
taneously charged with the supply water, or the rods be moved that the valves may
close against the flow of the supply water except to the first or to the combined
first and second vertical tubes of a row of such tubes, the valves being brought
against partitions in the boxes or pipes by a push in or draw out motion imparted
to the rods by screw or other means from outside the boxes or pipes, the valves
for the time being located permanently or temporarily according to circumstances,
and as desired.
The boxes or supply pipes with my shiftable valve and rod arrangement within
them and horizontally both at top and bottom may have vertical tubes, say, six
or more, and constituting a set ready for being fitted into the flueway of a furnace
for heating the water in such boxes or pipes and tubes previous to its use, say, for
the heating of feed water for a boiler, or if the boxes or the pipes containing the
valves and rods be provided with side branches, other boxes or pipes without
valves and rods but having sockets with other vertical tubes can be secured to them
to constitute series or nests of vertical tubes up or down or through which the
water can flow the series or nests of tubes with their transversely arranged boxes
or pipes in order that the transverse branch box or pipe of one row of vertical
tubes, or two of such rows of vertical tubes may be collectively charged with the
supply water, or the next row, or the next two rows and its or their respective
transverse boxes or pipes by the arrangement of the valves and rods in the supply
boxes or pipes, the next adjoining row or next two adjoining rows of vertical tubes
with their boxes or pipes can be collectively charged with the supply water before
the water flows in the reverse direction, down or up the next row, series, or nests
of vertical tubes and their respective transverse boxes or pipes, or by shifting the
valves and rod of one box or pipe to the requisite position with relation to the
position of the valves and rod of the other box or pipe in or to which the trans-
verse boxes or pipes having vertical tubes affixed, the whole of the boxes of one
row may be up flow tubes and the next row of the next transverse box or pipe
the down flow for the water and so on alternately, or by the shift of the valves
two of such transverse boxes and two rows of vertical tubes may be for up flow
of water, and the next transverse boxes or pipes and vertical tubes connecting
them be for the down flow of the water, and so on in rows transversely alone or
in conjunction with other vertical tubes of the lower or of the upper valve box
or pipe.
Said valve boxes or pipes can be arranged at diametrically opposite corners of a
stack of boxes or pipes and tubes and the connection between one set or series of
tubes may be by branch pipes which may be arranged according to any desired
arrangement for the flow or passage of water.
My invention will be more fully understood by reference to the annexed draw-
ings in which
Figure 1 shows in sectional elevation top and bottom boxes or pipes
provided with internal ribs and with valves on rods set in position for water to
flow up all the tubes simultaneously and to the upper box and away through the
outlet.

page_text: Figure 2 represents in vertical section the same boxes or pipes and tubes with
the valves moved along for the supply water to flow up the first tube and down the
next tubes and so on in succession to the outlet.
Figure 3 a similar vertical sectional elevation of the same boxes or pipes and
tubes with the valves moved for the water to flow up the first two tubes and down
the next two tubes, and so on to the outlet orifice, as indicated by the arrows.
Figure 4 sectional elevation similar to Figure 1, except that the ribs in the
boxes or pipes are of about three quarter segments of a circle only, the other
fourth being of the box or pipe itself on which the valves and rods are supported
between the end caps of the boxes or pipes,
Figure 5 sectional plan of lower and upper boxes or pipes having the valves
arranged for single tube flow into horizontal valveless boxes or pipes set trans-
versely which have branches for vertical tubes, all the tubes of each transverse
row being alternately for up flow and down flow in succession by the arrangement
of the valves in the upper box and in the lower box respectively.
Figure 6 side elevation partly in section of a lower valve box or pipe, lower
transverse valveless boxes or pipes, upper valveless boxes or pipes with vertical
tubes connecting, and upper valve box or pipe for return of water down cach
alternate row of tubes of which there may be any number to suit the extent of
capacity available for fitting them. This view is taken through the lines x, x,
of Figure 7.
Figure 7 end elevation of lower and upper boxes arranged transversely and pro-
vided with vertical tubes for flow from and to the valve containing pipes, these
being at diametrically opposite portions of the structure as before explained.
Similar letters of reference in the several figures indicate the same parts.
A, water inlet pipe. B, lower box or pipe. C, vertical tubes set in sockets D
of the lower box B. E, upper box or pipe with sockets F for upper ends of
tubes C. G, valves in lower box or pipe.. H, valves in upper box or pipe, said
valves G, H, being on rods I, J, operable by hand wheels K, L, as desired. The
rods I, J, are screw threaded near one end and work in threaded sockets M, N,
of the inner ends of the boxes or pipes B and E where each has a gland P to make
the joint watertight, the opposite or outer ends of the rods being in cup caps Q
of the ends.
R, R, are ribs in the boxes or pipes B, E, into which the valves can be moved
when the hand wheels K, L, are turned to close some of the passages and to open
others according to the desired direction of flow.
S, T, are outlets for the heated water, either or both of which can be used
according to the arrangement of the valves. T can also be used as the blow off
opening in the lower box or pipe in relation to each or to a series of vertical tubes,
or one blow off can be common to all the vertical tubes.
U, U, are lower transverse boxes or pipes connected at right angles by
sockets V, V, to the lower valve box or pipe B, and C, C, are vertical tubes there-
from.
W, W, are the upper transverse boxes connected by sockets X, X, to the vertical
pipes C and also by sockets Y, Y, with the upper valve box E.
In all the figures, I have shown that the supply water enters at the lower valve
box or pipe, but it can be entered at the outlet orifice S, and in that case the
water would flow down the first vertical tube and then rise up the other or others
according to the disposition of the valves in the valve boxes or pipes.
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:-
1. A fuel economiser consisting of horizontal boxes or pipes B, E, containing
valves G, H, on rods I, J, operable for end on motion, said boxes B, E, being con-
nected by vertical tubes C, C, substantially as specified.
2. A fuel economiser consisting of horizontal boxes or pipes B, E, containing

page_text: valves G, H, on rods I, J, operable for end on motion, said boxes B, E, being con-
nected to transverse horizontal boxes or pipes U, W, and vertical tubes C, C,
substantially as specified.
