Bradford aforesaid, Foreman Boiler Maker, and WILLIAM HENRY SMITH of
23 Vere Street Ripley Ville Bradford aforesaid do hereby declare the nature of this
invention to be as follows :—
This invention relates to improvements in steam generators or boilers of the
vertical type and its object is to provide more efficient heating surface in this class
of boiler without materially complicating the construction or in any way preventing
free access to the interior.
The
Our improvements consist in employing a combustion chamber above the fire box
but below the water line and connected to such fire box by a series of tubes.
flue is formed in the side of said chamber and is preferably arranged to be used as
a man-hole to facilitate inspection and repairs of the interior of the chamber and
tubes. The combustion chamber is stayed above to the top of the shell and below
to the fire box in any suitable manner. Mud holes are formed in the shell to give
access to the tubes and also at other usual parts of the shell.
The top of the combustion chamber may be provided with what are known as

23 Vere Street Ripley Ville Bradford aforesaid 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 steam generators or boilers of the
vertical type, and its object is to provide more efficient heating surface in this class
of boiler, without materially complicating the construction or in any way preventing
free access to the interior.
In the accompanying sheet of explanatory drawings Fig. 1 is a sectional
elevation of our improved boiler and Fig. 2 is a part sectional plan.
Our improvements consist in employing a combustion chamber A. above the fire
box B but below the water line and connected to such fire box by a series of
tubes.

page_text: The flue D is formed in the side of said chamber A and is preferably arranged
to be used as a man-hole D' to facilitate inspection and repairs of the interior of the
chamber and tubes. The combustion chamber is stayed above to the top of the
shell and below to the fire box in any suitable manner conveniently by stays E as
shown.
Mud-holes F are formed in the shell to give access to the tubes C and also at
other usual parts of the shell.
The top of the combustion chamber may be provided with what are known as
"Field "tubes H hanging down into the chamber.
We make the tube plates dished or straight as may be desired.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1. The combination and arrangement of a vertical steam generator having an
intermediate combustion chamber, arranged above the fire box with connecting tubes
provided between, substantially as herein before described and illustrated in the
accompanying drawings.
2. In a vertical steam generator the arrangement of a combustion chamber having
"Field" type tubes above and ordinary tubes below the smoke box outlet,
substantially as herein before described and illustrated in the accompanying
drawings.
