Improvements in or connected with the Funnels of Portable,
Locomotive, and Marine Boilers, or other Iron Chimneys.
1, ERNEST LODGE NEWSOME, of 11, Kent Road, Blackpool, in the County of
Lancaster, Minoral Water Manufacturer, do hereby declare the nature of this
invention to be as follows:-
This invention is designed to provide for the heating of the feed water for
portable locomotive and marine boilers and also for the utilization of some of the
wasto heat from other iron chimneys such as furnace chimneys and the like.
It consists essentially in constructing the funnel or chimney with a water jacket
or circulating water chamber around it into which the feed water passes and from
which it is pumped forced or conveyed to the boiler.
Around the funnel or chimney I enclose a space by plates of sufficient thickness
to withstand any required pressure and this I connect by pipes and valves with the
boiler or to a pump or other forcing apparatus. The feed water is lifted into this
chamber where it absorbs some of the waste heat from the chimney or funnel and
is thereby heated."
For portable and traction engines especially I consider that a considerable
saving will result.

COMPLETE SPECIFICATION.
Improvements in or connected with the Funnels of Portable,
Locomotive, and Marine Boilers, or other Iron Chimneys.
I, ERNEST LODGE NEWSOME, of Kent Road, Blackpool, in the County of
Lancaster, Mineral Water 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 is designed to provide for the heating of the feed water for
portable locomotive and marine boilers and also for the utilization of some of the
waste heat from other iron chimneys such as furnace chimneys and the like.
It consists essentially in constructing the funnel or chimney and smoke box
with a water jacket or circulating water chamber around it into which the feed
water passes and from which it is pumped forced or conveyed to the boiler.
It will be fully described with reference to the accompanying drawing in which
as an example the invention is shown applied to a portable boiler.
Fig. 1. side elevation.
Fig. 2. front sectional elevation through funnel and smoke box.
The
The boiler A and furnace B are of the ordinary construction around the funnel
or chimney C and also preferably around the smoke box D. I enclose a space
or chamber E to form a water, jacket or water circulating chamber.
chamber E is enclosed by plates e of suitable strength and thickness to withstand
tho required pressure.
The chamber E is connected at or near the bottom by the pipe F with a feed
pump or injector and at or near the top by the pipe G with the water space of
the boiler a back pressure valve H being placed at the junction of the pipe F
with the boiler.

page_text: The funnel C is shown jointed at I by'a flanged joint. The funnel may be fitted
with any desired number of similar joints.
The joint I may be constructed with a number of holes through tho flanges for
the passage of the water. Each hole in one preferably 'the lower flange is fitted
with a small copper tube and each hole in the top. flange is made tapered
to fit over the tube projecting from the bottom one and thus a watertight joint
is secured.
.
Instead however of the holes through the flanges the passage for the water may
be formed by two bent pipes I¹ one attached above the flange and the other below
it and connected together by a union or other coupling it.
A mud hole K will be placed at or near the bottom of each chamber to enable
mud or sediment to be cleaned out occasionally and another door or opening L
at or near the top of the funnel through which access can be had to the chamber
at the top.
The cold water supply from the pump or injector is forced into the chamber E
through the pipe F wherein it absorbs and becomes heated by the waste heat
passing up the funnel.
The feed water as it is forced in at F into the chamber E gradually ascends and
becomes heated until it reaches the pipe G at the top of the funnel which conveys
it through the back pressure valve H to the boiler A.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I deolare that what I
claim is
1. A portable, locomotive, marine, or similar boiler having a chamber forming
a water jacket round the funnel and smoke box through which the feed water is
forced to absorb the waste heat substantially as described.
2. In a portable, locomotive,, marinė, or similar boiler the combination with the
funnel and smoke box of the chamber E surrounding them through which the feed
water passes the feed pipe F the return pipe G and tlie back pressure valve H
substantially as described and shown.
