PROVISIONAL SPECIFICATION left by the said William Beesley and James
Beesley at the Office of the Commissioners of Patents on the 2nd May 1882.
WILLIAM BEESLEY and JAMES BEESLEY of Barrow-in-Furness in the County of
Lancaster, "IMPROVEMENTS IN APPARATUS FOR TRANSMITTING HEAT TO LIQUID
TO GENERATE STEAM OR HEAT FEED WATER
"
This invention has for object to provide a strong, simple, and efficient vertical
steam boiler with a large amount of heating surface in small compass, self
contained, and easily accessible in all parts for examination, cleaning and repairing.
In one form of steam boiler according to our invention a vertical shell titted
with either flat dished, egg ended, or other suitably shaped crown is provided at its
lower part with a fire box that has a flat or slightly dished crown and the usual
fire-hole or holes. From the crown of the fire box a group or groups of tubes.
short in length and small in bore extend to an upper combustion box that has a
dished or other suitably shaped crown and a lower part which forms a tube plate.
A connection is formed from the side of this combustion box which is situated
below the water level to the shell of the boiler by a round or an oval tube. This tube
serves for the purpose of cleaning or affording access to the said combustion box
and debouches into a smoke box with suitable door or doors. The said smoke box
also acts as the base for the chimney. In cases where the chimney and smoke
box are not connected to the outlet of this tube, the opening is closed with an air
tight door. An outlet for the gases may then be provided by making the com-
bustion box of D shape and carrying from the flat side of it a number of horizontal
flue tubes to another tube plate fixed in a rectangular or other shaped box rivetted
to the outside of the shell. This external box answers for smoke box and a
chimney base. Where it is not desirable to adopt this arrangement an uptake is
inserted between the crown of the combustion box and the crown of the shell,

page_text: This uptake is of conical form the large end being uppermost so as to allow of its
being easily removed. Instead of this internal flue tube there may be inserted
from the combustion box crown to the crown of the shell a number of tubes of
suitable bore to act as uptakes and also to serve as stays to both crowns, these
tubes may be parallel and be screwed into both crowns; or they may be conical
tubes flanged at both ends and rivetted to both crowns with the large ends
uppermost to allow of their being easily removed. The smoke box in this arrange-
ment is conical or of other suitable shape and is fitted with a door or doors for
cleaning purposes. In some cases we dispense with a side chimney central uptake
and upper group of tubes and put in the fire box a fire brick wall dividing the
said box into two chambers one of which acts as the furnace while the other
constitutes a return flue leading to main flue. This last arrangement is particularly
applicable for utilising the waste heat from heating furnaces, the tubes in this case
being of larger bore and being inserted in tube plates and expanded in the usual
way, or the tubes may be flanged and rivetted to the fire box crown and the lower
crown of the combustion box.
In a boiler of large diameter with a number of fire holes constructed according
to our invention a central tube depends from the fire box crown, and has attached
to it one end of each of a series of U-shaped tubes connected at their other ends
to the sides and crown of fire box dividing the original cylindrical fire box into
separate fire boxes corresponding to the number of fire holes.
In cases where there is no connection between the shell and the combustion box
a man hole opening is put in the combustion box crown for the purpose of access
to its interior,
Under certain circumstances there may be substituted for the combustion box a
group of quadrant shaped tubes inserted at their lower ends into the crown of the
fire box and at their upper ends into a tube plate fixed in a nozzle or branch
rivetted to the outside of the shell at right angles to the fire box crown and
serving for smoke box and chimney base.
In a water heater according to this invention heated by exhaust steam, the
steam rises up one half of the tubes into the box hereinabove called the combustion
box and passes down the other half, a suitable double D shaped chamber being
attached to the bottom of the main shell for the purposes of inlet and outlet.

by the said William Beesley and James Beesley in the Great Seal Patent
Office on the 2nd November 1882.
WILLIAM BEESLEY and JAMES BEESLEY of Barrow-in-Furness, in the County of
Lancaster. IMPROVEMENTS IN APPARATUS FOR TRANSMITTING HEAT TO LIQUID
TO GENERATE STEAM OR HEAT FEED WATER,
This invention has for object to provide a strong, simple, and efficient vertical
steam boiler, with a large amount of heating surface in small compass, self con-
tained and easily accessible in all parts for examination, cleaning and repairing.
In a steam boiler according to our invention a vertical shell, fitted with either
flat, dished, egg ended or other suitably shaped crown is provided at its lower
part with a fire box that has a flat crown and the usual fire hole or holes.
From the crown of the fire box a group of quadrant shaped tubes, inserted.
into it at their lower ends, extend to a plate fixed in a nozzle or branch rivetted
to the outside of the shell at right angles to the fire box crown and serving for
smoke box and chimney base.
Referring to the accompanying sheet of drawings Fig. 1 is an elevation of a
steam boiler according to our invention with one side of the smoke box door
removed
being surrounded by a ring in the usual way.
The part of the shell below the fire bars constitutes the ash-pit, and is cut away
in front to permit access of air.
The top of the furnace or fire box is closed by a tube plate d into which is
inserted one end of each of a number of quadrant shaped tubes e, the other ends
of which pass through a second tube plate f let into or forming part of the shell a
and enter the smoke box g.
The chimney h is mounted on the top of the smoke-box.
The generator is provided with all necessary fittings such as safety valvo, man-
hole and mud doors.
In our provisional specification we described several other modifications of
boiler.
In one of these a group of tubes short in length and small in bore extended
from the crown of the firebox to an upper combustion box that had a dished or
other shaped crown and a lower plate which formed a tube plate.
A connection was formed from the side of this combustion box, which was
situated below the water level, to the shell of the boiler by a round or oval tube.
This tube debouched into a smoke box with suitable door or doors, which smoke
box also acted as the base for the chimney
We also stated that in cases where the chimney and smoke box were not
connected to the outlet of this tube the opening was to be closed with an air tight
door. An outlet for the gases could then be provided by making the combustion
box of D shape and carrying from the flat side of it a number of horizontal flue
tubes to another plate fixed to a rectangular or other shaped box, rivetted to the
outside of the shell
This external box answered for smoke box and chimney base.

page_text: When it was not desirable to adopt this arrangement we proposed that an
uptake should be inserted between the crown of the combustion box and the crown
of the shell.
This uptake was to be of conical form, the large end being uppermost so as to
allow of its being easily removed.
We also stated that instead of this internal flue tube there might be inserted
from the combustion box crown to the crown of the shell a number of tubes of
suitable bore to act as uptake and also to serve as stays to both crowns.
The smoke box in this arrangement was conical or of other suitable shape and
was fitted with a door or doors for cleaning purposes.
In some cases we propose to dispense with a side chimney, central uptake and
upper group of tubes and put in the fire box a fire brick wall dividing the said
box into two chambers, one of which acted as the furnace while the other con-
stituted a return flue leading to the main flue.
We also propose to construct a boiler of large diameter with a number of fire
holes and a central tube depending from the fire box crown having attached to it
one end of each of a series of U shaped tubes connected at their other ends to the
sides and crown of the fire box dividing the original cylindrical fire box into
separate fire boxes corresponding to the number of fire holes.
We, however, do not now consider either of these several arrangements to be so
advantageous as the one illustrated in and hereinabove described with reference to
the accompanying drawings.
We also described in our provisional specification a water heater heated by
exhaust steam; the steam rose up one half of the tubes into the box and passed
down the other half, a suitable double D shaped chamber being attached to the
bottom of the main shell for the purposes of inlet and outlet but we do not now
lay claim to this arrangement..
Having thus described the nature of our said Invention and the manner in
which it is to be performed we would have it understood that what we consider
to be novel and original and therefore claim as secured to us under the Letters
Patent herein before in part recited is :-
1. In apparatus for generating steam the use in combination with two tube
plates arranged at right angles to each other, and connected respectively to the
firebox and the boiler shell, of quadrant shaped tubes, forming a communication
between the external sides of the said tube plates substantially as described.
2. The improved steam generator constructed, arranged and operating as shewn
in and described with reference to the drawings.
In Witness whereof we the said William Beesley and James Beesley have
hereunto set our hands and seals this twenty eighth day of October in
the year of Our Lord one thousand Eight hundred & Eighty two.
