We, WILLIAM BEESLEY and JAMES BEESLEY, both of the Furness Boiler Works,
Barrow-in-Furness, in the county of Lancaster, Boiler Makers, do hereby declare the
nature of this invention to be as follows:-
This invention relates generally to steam boilers of the marine type in which the
products of combustion pass from the furnace through tubes into a terminal or end
combustion chamber and then pass back through other tubes, being more particularly
applicable to the construction of boiler described and shewn in the specification and
drawings of Letters Patent No. 3020 granted to us March 3rd 1886 in which waste
heat from puddling, forge, mill, or other furnaces is passed horizontally through a
lower tube into an end chamber where it is divided and returns through two upper
tubes. In the specification and Drawings referred to the end chamber is described and
shewn as being arranged so as to be surrounded by the water in the boiler. According to
this invention we do away with the water space between the back of the chamber and
the boiler end by making the end plate of the boiler into the back plate of the
combustion chamber and thus dispense entirely with screwed and rivetted stays
between the said plates.
We preferably line the inner face of the back plate of the combustion chamber with
fire-brick or other refractory material which (more especially in marine boilers) serves
not only as a protecting medium for the rivets and caulking edges of the combustion
chamber plates and the boiler end generally but also acts when highly heated as a
regenerator for igniting the impinging gases from the furnaces after they have been
newly re-charged with fuel. The arrangement as above described allows of a hinged
door and manhole through the back of the combustion chamber that is to say through
the boiler end a convenient means of access to the interior of the chamber and to that
of the tubes for cleaning or other purposes being thereby provided.

Improvements in the Construction of Steam Boilers.
We, WILLIAM BEESLEY and JAMES BEESLEY, both of the Furness Boiler Works,
Barrow-in-Furness in the County of Lancaster, Boiler Makers, 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 generally to steam boilers of the marine type in which the 5
products of combustion pass from the furnace through tubes into a terminal or end
combustion chainber and then pass back through other tubes, being more particularly
applicable to the construction of boiler described and shewn in the specification and
drawings of Letters Patent No. 3020 granted to us March 3rd 1886 in which waste
heat from puddling, forge, mill, or other furnaces is passed horizontally through a
lower tube into an end chamber where it is divided and returns through two upper
tubes. In the specification and drawings referred to the end chamber is described
and shewn as being arranged so as to be surrounded by the water in the boiler.
According to this invention we do away with the water space between the back of the
chamber and the boiler end by making the end plate of the boiler into the back plate
of the combustion chamber and thus dispense entirely with screwed and rivetted stays
between the said plates.
In the accompanying Drawings.
Fig. 1 is a sectional view of the chamber end portion of a boiler constructed
according to our said Patent No. 3020 of 1886.
Fig. 2 is a front end view and
Fig. 3 is a longitudinal section of a marine type of boiler our invention being
shewn as applied to both constructions of boiler.
In Fig. 1 the products of combustion or waste heat pass from a lower tube a into
the chamber band return through two upper tubes e (of which only one is shewn in
the drawing).
In Figs. 2 and 3 the products of combustion pass from the lower tubes a a into
the chamber band return through a number of upper tubes c c.
We preferably line the inner face of the back plate d of the combustion chamber b
with fire-brick or other refractory material e which (more especially in marine boilers)
serves not only as a protecting medium for the rivets and caulking edges of the
combustion chamber plates and the boiler end generally but also acts when highly
heated as a regenerator for igniting the impinging gases from the furnaces after they
have been newly recharged with fuel. The arrangement as above described allows of
a hinged door and manhole g through the back of the combustion chamber that is
to say through the boiler end, a convenient means of access to the interior of the
chamber and to that of the tubes for cleaning or other purposes being thereby
provided

page_text: Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, we declare that what we claim is :-
1. In steam boilers in which the products of combustion or waste heat pass in one
direction from a tube or tubes into an end chamber and return therefrom in the
opposite direction through other tubes constructing such end chamber so that the end
plate of the boiler constitutes the back plate of the chamber substantially as described,
and shown in the drawings.
2. In steam boilers constructed as hereinabove described lining the inner face of
the back plate of the end chamber with refractory material substantially as described
and shewn in the drawings for the purpose or purposes set forth.
3. Making the end plate of steam boilers constructed as hereinabove described with
a manhole arranged substantially as described and shown in the drawings for the
purpose set forth.
Dated this 2nd day of September 1887.
