Improvements in Steam Generators.
I, THOMAS WHITAKER, of Summerfield, Horsforth, near Leeds, in the County
of York, Contractor, do hereby declare the nature of this invention to be as
follows:-
This invention relates to steam generators of the vertical tubular type such as
are applicable for working steam cranes excavating machines and other portable
machines and is designed to secure or obtain a larger heating surface than has
hitherto been the case in this class of steam boiler.
I construct the boiler with a number of vertical tubes leading from the fire box
which may be of ordinary or suitable construction. Above the vertical tubes
is placed or arranged a horizontal combustion chamber cylindrical or of other
shape in cross section to which the upper ends of the tubes are attached. The
combustion chamber is closed on top and open at both ends so that the flames
and heated products of combustion passing through the tubes come in contact
with the top of the combustion chamber which provides a heating chamber over
its whole extent.
The funnel or chimney is connected by a flue or smoke box with one end of the
combustion chamber and a lid or door is provided to close the other end and to
provide access for cleaning or for repairs.
I find by this arrangement and construction of the parts of the generator I
get a very great heating surface.

Improvements in Steam Generators.
I, THOMAS WHITAKER, of Summerfield, Horsforth, near Leeds, in the County
of York, Contractor, 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 steam generators of the vertical tubular type such as
are applicable for working steam cranes excavating machines and other machines
either portable or stationary and is designed to secure or obtain a larger heating
surface than has hitherto been the case in this class of steam boiler.
The invention will be fully described with reference to the accompanying
drawings.

-.
The boiler is constructed with a cylindrical shell A and fire box B of the
ordinary form.
From the top of the fire box B a number of tubes C extend vertically through
the water space D to a horizontal combustion chamber E to which the upper
ends of the tubes are attached.
The horizontal combustion chamber E is of cylindrical or other shape in cross
section closed on top and open at both ends so that the flames and heated products
of combustion passing through the tubes come in contact with the top of the
combustion chamber which provides a heating chamber over its whole extent.
At one end of the combustion chamber E is placed a flue or smoke box F to
which the funnel or chimney G is attached and at the other end a lid or door H
is placed to close it and also to provide access to the combustion chamber and
to the tubes C for the purpose of cleaning er for repairs.
The smoke box F is also fitted with a door K whereby the combustion chamber
can be thrown open from end to end.
I find by this arrangement and construction of the parts of the generator I
get a very great heating surface.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is: :―
1. In a vertical steam boiler the combination with the fire box and vertical
tubes of a horizontal combustion chamber closed at the top and open at one end
leading to a smoke box and chimney substantially as described.
2. A vertical steam boiler with the several parts constructed and arranged in
combination substantially as described and shown.
