PROVISIONAL SPECIFICATION.
Improvements for the Heating of Steam Boiler Feed Water, and for
the Protection from Overheating of what are known as Vertical
Boiler Uptakes.
THOMAS FLETCHER PASSMAN Boiler Maker Depot Road Middlesbro do
hereby declare the nature of this invention to be as follows:-
It relates to improvements for the heating of feed water and for the protection
from overheating of what are known as a vertical steam boiler uptake.
It consists of a cylinder or any other shaped vessel or water-pot made of
wrought iron, steel or any kind of metal in segments which are fixed jointed
and bolted together and made water tight round the uptake in the interior of
the boiler and so forming a water space of one or more inches as size of the
uptakes may require.
Through the shell of the boiler to the side or bottom of the vessel or water-pot
is fixed the water feed pipe so that when the boiler is feeding water by the
injector, pump or any other appliance for feeding steam boilers with water, the
water enters and rises to the top of the said vessel or water-pot, completely
surrounding the uptake with water which will absorb the waste heat in the uptake
above the water line in the steam space, and so heating the water as it rises to the
top of the vessel or water-pot which overflows into the water below and so
preventing the uptake from overheating and feeding the boiler with water at a
very high temperature.
.
From the opposite side or bottom of the vessel or water-pot through the shell
of the boiler is fixed a pipe to a steam or water-cock attached to the side of
boiler shell for the purpose of blowing-out occasionally the sediment or dirt that
may accumulate in the feed water which is blowing-out by the steam in the
boiler.

Improvements for the Heating of Steam Boiler Feed Water, and for
the Protection from Overheating of what are known as Vertical
Boiler Uptakes.
THOMAS FLETCHER PASSMAN Boiler Maker Depot Road Middlesborough-
on-Tees 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 for the heating of feed water and for
the protection from overheating of what are known as vertical steam boiler
uptake.
It consists of a cylinder or any other shaped vessel or water-pot, made of
wrought iron, steel, or any kind of metal in segments which are fixed, jointed and
bolted together and made water tight round the uptake in the interior of the
boiler so forming a water space of one or more inches as size of the uptake may
require.
Through the shell of the boiler to the side or bottom of the vessel or water-pot
is fixed the water feed pipe so that when the boiler is feeding water by the
injector pump or any other appliance for feeding steam boilers with water, the

page_text: water enters and rises to the top of the said vessel or water-pot completely
surrounding the uptake with water which will absorb the waste heat in the
uptake above the water line in the steam space, and so heating the water as
it rises to the top of the vessel or water-pot which overflows into the water
below and so preventing the uptake from overheating and feeding the boiler with
water at a very high temperature.
From the opposite side or bottom of the vessel or water-pot through the shell of
the boiler is fixed a pipe to a steam or water cock attached to the side of boiler
shell for the purpose of blowing-out occasionally the sediment or dirt that may
accumulate in the feed water which is blown-out by the steam in the boiler.
In reference to the drawings annexed the nature of this invention will be more
clearly seen by the following description, viz. Figure No. 1 sectional elevation,
A, boiler shell, B, fire-box, crown, ¡C, uptake, D, steam space, E, water-space,
in water pot, F, water-pot joints G, water-pot bottom fixed onto uptake,
H, overflow pipe, I, feed-pipe, J, blow-out cock.

D, steam space, E, water space in water-pot, F, water-pot joints, G, water pot
bottom fixed round uptake, H, over-flow pipe, I, feed pipe, J, blow-out cock.
Having now particular described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
The arrangement of the cylinder, or any other shaped vessel or water-pot placed
round the uptake of vertical steam boiler, for the purpose of heating the feed
water, and for the protection from overheating of vertical steam boiler uptakes.
