PROVISIONAL SPECIFICATION.
Improvements in Steam Boilers.
I, JOSEPH HALL, of 5 Sea View, Grangetown, Cardiff, Marine Engineer, do
hereby declare the nature of this invention to be as follows:-
-
This invention relates to steam boilers and. has for its objects to economise fuel
and to utilize heat more efficiently.
According to this invention, the combustion chamber is of increased dimensions
affording extended space for combustion of the gases evolved from the fuel. A
further improvement consists in the provision between the back of the boiler and
the combustion chamber of a series of heating tubes open at the inner end to the
said chamber, and at the outer end to an uptake leading to the smoke stack. By
the provision of this series of tubes greater heating surface is obtained. In order
to provide for the extended combustion space and the tubes aforesaid, the furnace
is made somewhat shorter than is usual.

COMPLETE SPECIFICATION.
Improvements in Steam Boilers.
I, JOSEPH HALL, of 5 Sea View, Grangetown, Cardiff, Marine 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 steam boilers, and has for its objects to economise fuel
and to utilize heat more efficiently..
According to this invention, the combustion chamber is of increased dimensions
affording extended space for combustion of the gases evolved from the fuel. A
further improvement consists in the provision between the back of the boiler and
the combustion chamber of a series of heating tubes open at the inner end to the
said chamber, and at the outer end to an uptake leading to the smoke stack. By
the provision of this series of tubes greater heating surface is obtained. In order
to provide for the extended combustion space and the tubes aforesaid, the furnace
is made somewhat shorter than is usual.
In the accompanying drawing
Fig. 1 represents, partly in transverse section and partly in end elevation, a
marine boiler constructed and arranged in accordance with this invention. Fig. 2
is a vertical section.
The combustion chamber a is of increased dimensions and consequently affords
extended space for combustion of the gases evolved from the fuel.
Between the back of the boiler and the combustion chamber a is a series of
tubes b open at one end to the chamber, and at the other to the uptake c leading to
the smoke stack d.
In order to provide for the series of tubes c and for the extended combustion
chamber a the furnace e is made somewhat shorter than is usual in marine boilers,
Sliding doors fare fitted at each side of the boiler,

page_text: Having now particularly 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 :-
In a steam boiler, the provision of a combustion chamber such as a from the back
and front of which are extended tubes communicating with the chamber and with
uptakes to the smoke stack, substantially as hereinbefore described and shown in
the accompanying drawings.
Dated this 16th day of August 1893.
