Improvements in or Appertaining to Apparatus for Heating and
Purifying the Feed Water of Locomotive or other Steam
Boilers.

Engineer.
I, WILLIAM PHILLIPS THOMPSON, F.C.S. M.I.M.E. of the Agency for Foreign
Patent Solicitors 6, Lord Street Liverpool and 6, Bank Street Manchester both in
the County of Lancaster & 323 High Holborn in the County of Middlesex Civil
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in feed water, heating, and purifying
apparatus, in which water and filter chambers placed between two shells and
encircling the smoke flue of a smoke stack are made to operate in conjunction with a
feed water pipe, and an inlet pipe placed within the flue of a smoke stack, and a blow
off pipe attached to the smoke stack, and the objects of the improvements are to
economize fuel by filtering and heating the feed water of a locomotive, or other
steam boiler when in transit from pump to boiler, by utilizing the hot gases generated
by combustion and which pass off through the flue of a smoke stack.
These objects are attained by the mechanism illustrated in the accompanying
drawings, in which :-
Figure 1 is a vertical sectional view of a smoke stack, showing smoke flue, water
and filter chambers, and pipes.
Figure 2 is a side elevation partly in section.
Figure 3 is a cross sectional view.
Similar letters refer to similar parts throughout the several views:-
In constructing the apparatus two cylindrical shells of different diameters are used
for the smoke stack as shown in Figure 1, A being the exterior shell, and B, the
interior shell, the latter forming the flue of the smoke stack, with an inlet or discharge
pipe G, placed therein for feeding water into the boiler, and between said shells are
water chambers, as shown by M and N, said water chambers being separated by
filtering plates E, which form a fitering chamber, said plates being perforated, and
held in position by means of bolts; H is a suitable filtering material; D is the base
attached to boiler L, and at the top of smoke stack, as shown by C, a flange is placed
which forms a cover for water chambers; I is a feed water pipe by which water is
fed from the tender tank, or reservoir by means of a pump, injector, or water forcer,
and to which there is attached a check valve F; K is a blow off, or waste pipo which
is also provided with a stop cock O; J is a feed valve to close in danger; L is the
boiler; P is a hood.
The mode of operation is as follows:-
The water from a tender tank of a locomotive, or reservoir is forced by a pump or
any desired device through feed water pipe I, and passes into the lower water
chamber, thence through filter chamber, and enters the top or filtered water chamber,
the filtration being accelerated by the generation of heat from the smoke flue, and
the water is carried from the top chamber M, into the boiler L through pipe G, said
pipe being situated within the smoke flue, and by means of hot gases escaping
through said flue the water within pipe G is again heated before entering the
boiler.
A striking advantage of this invention is that it allows the utilisation of the
heretofore wasted gases generated, and passing off through the flue of a smoke stack,

page_text: and it will be obvious that there will be less fuel used than is now required by
the old svstein.
This invention is designed more particularly for locomotive boilers, but may be
used for other purposes, water may be fed into the apparatus by any improved means
not shown, and many slight changes might be made in minor details of construction,
hence the invention is not limited to the exact construction shown.

Improvements in or Appertaining to Apparatus for Heating and
Purifying the Feed Water of Locomotive or other Steam
Boilers.
A communication from abroad by WILLIAM WILSON SUTCLIFFE, of 42, Decatur Street,
in the City of New Orleans, State of Louisiana, United States of America,
Engineer.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6 Lord Street, Liverpool, and 6, Bank Street, Manchester, both in
the County of Lancaster, and 323 High Holborn in the County of Middlesex, Civil
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 :-
This invention relates to improvements in feed water, heating and purifying
apparatus, in which water and filter chambers placed between two shells and
encircling the smoke flue of a smoke stack are made to operate in conjunction with
a feed water pipe, and an inlet pipe placed within the flue of a smoke stack, and a
blow off pipe attached to the smoke stack, and the objects of the improvements are to
economise fuel by filtering and heating the feed water of a locomotive, or other
steam boiler when in transit from pump to boiler, by utilising the hot gases
generated by combustion and which pass off through the flue of a smoke stack.
These objects are attained by the mechanisın illustrated in the drawings
accompanying the provisional specification, in which :—
Figure 1 is a vertical sectional view of a smoke stack, showing smoke flue, water
and filter chambers, and pipes.
Figure 2 is a side olevation partly in section.
Figure 3 is a cross sectional view.
Similar letters refer to similar parts throughout the several views.
In constructing the apparatus, two cylindrical shells of different diameters are
used for the smoke stack as shown in Figure 1, A being the exterior shell, and
B, the interior shell, the latter forming the flue of the smoke stack, with an inlet or
discharge pipe G, placed therein for feeding water into the boiler, and between said
shells are water chambers, as shown by M and N, said water chambers being
separated by filtering plates E, which form a filtering chamber, said plates being
perforated, and held in position by means of bolts; H is a suitable filtering
material ; D is the base attached to boiler L, and at the top of smoke stack, as
shown by C, a flange is placed which forms a cover for water chambers; I is a feed
water pipe by which water is fed from the tender tank, or reservoir by means of a
pump, injector, or water forcer, and to which there is attached a check valve F;
K is a blow off, or waste pipe which is also provided with a stop cock O ; J is a feed
valve to close in danger; L is the boiler; P is a hood.
The mode of operation is as follows :-
The water from a tender tank of a locomotive, or reservoir is forced by a pump
or any desired device through feed water pipe I, and passes into the lower water
chamber, thence through filter chamber, and enters the top or filtered water chamber,

page_text: the filtration being accelerated by the generation of heat from the smoke flue, and
the water is carried from the top chamber M, into the boiler L through pipe G,
said pipe being situated within the smoke flue, and by means of hot gases escaping
through said flue the water within pipe G is again heated before entering the
boiler.
A striking advantage of this invention is that it allows the utilisation of the
heretofore wasted gases generated, and passing off through the flue of a smoke stack,
and it will be obvious that there will be less fuel used than is now required by the
old system.
This invention is designed more particularly for locomotive boilers, but may be
used for other purposes, water may be fed into the apparatus by any approved
means not shown, and many slight changes might be made in minor details of
construction, hence the invention is not limited to the exact construction shown.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is :-
1. An apparatus for feeding and purifying feed water for locomotive or other
steam boilers consisting of a water chamber surrounding the smoke flue of the
boiler furnace and provided with a suitable inlet and outlet and of filtering material
located intermediately to said inlet and outlet in such manner that the feed water has
to pass through it before reaching the outlet, substantially as described.
2. In combination with the smoke flue of a boiler furnace, the combined filtering
and water heating chambers arranged as described, the said water chamber being
provided at one side of the filtering chamber with a suitable inlet pipe and at the
opposite side of said filtering chamber with an outlet pipe, one or both of said pipes
lying partly within said flue, substantially as described.
3. The combination of parts forming a feed water heater and purifier for a
locomotive boiler taken as a whole, substantially as described and shown.
