page_text: I, WILLIAM DEIGHTON, of One Ash, Hall Lane, New Leeds, Leeds, in the County
of York, Engineer, do hereby declare the nature of this invention to be as
follows:-
-
My present invention has reference to certain improvements in vertical steam
generators, and consists of or in the combination of a flue or fire box, and one or
more combustion chambers of decreasing diameter arranged one above the other,
with an outside shell or casing.
A series of vertical tubes are provided through which the products of com-
bustion are conducted from the fire box and combustion chamber or chambers
to the smoke box, and afterwards discharged into the flue or chimney.
A flue or chimney provided with a suitable damper may also be attached to
the crown of the uppermost combustion chamber, and carried out through the
crown of the shell or casing.
The fire box and combustion chamber or chambers may be circular in cross
section, or of other convenient shape, and may be plain, corrugated, ribbed, or
of other section longitudinally to its axis as desired and may also be provided with
cross tubes.

I, WILLIAM DEIGHTON, of One Ash, Hall Lane, New Leeds, Leeds, in the County
of York, 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: -
.
My present invention has reference to certain improvements in vertical steam
generators, and consists of or in the combination of a flue or fire box, and one or
more combustion chambers of decreasing diameter arranged one above the other,
with an outside shell or casing.
A series of vertical tubes are provided through which the products of com-
bustion are conducted from the fire box and combustion chamber or chambers
to the smoke box, and afterwards discharged into the chimney.
An auxiliary chimney with a suitable damper may be attached to the crown

page_text: or the uppermost combustion chamber, and carried out through the crown of
the shell, if required.
The fire box and combustion chamber or chambers may be circular in cross
section or of other convenient shape, and may be plain, corrugated, ribbed, or
other section longitudinally to the axis as desired, and may also be provided with
cross-tubes.

For the purpose of illustrating my invention, I append 3 sheets of explanatory
drawings in which
Fig. 1. Sheet. 1. is a sectional elevation of a steam generator constructed
according to my invention.`
Fig. 2. is a sectional plan of same on the line x. x..
Fig. 3. Sheet. 2. is a sectional elevation shewing a modification.
Fig. 4. being a sectional plan of same on the line. c. a.
Fig. 5. Sheet. 3. is a sectional elevation shewing a further modification, and
Fig. 6. is a sectional plan of same on the line x. x.
In all the figures similar letters indicate like parts.
In Fig. 1. Sheet. 1. is shewn a vertical steam generator in which a, represents
the fire box, the combustion chamber b, of smaller diameter being placed above it,.
and attached thereto by the flanged ring c, the said combustion chamber and fire
box having corrugations d, at right angles to their axes.
The upper end of the combustion chamber is closed by the dished plate 61.
e, e, e, are cross tubes passing through the combustion chamber b, and com-
municating with the water space on each side, which is enclosed by the shell f,
the upper part f¹, being dome shaped and of smaller diameter. A flanged ring 9,
connects the upper and lower shells f¹, and f.
Vertical tubes h, are arranged round the combustion chamber b, the said tubes
passing through the water space, convey the products of combustion from the
fire box a, and combustion chamber b, (in the direction of the arrows) to the
smoke box j, where they pass out through the chimney k, in the crown of
the smoke box casing 1.
The fire grate m, is carried by a ring p, attached to the bottom of the shell f,
and a vertical stay q, is attached to the crowns of the combustion chamber b,
and upper shell f¹.
In the modification illustrated on Sheet. 2. Figs. 3, & 4, increased water and steam
space is provided by the shell f, being made tapered, and the tubes h, arranged
in an inclined position.
A further modification is shewn on Sheet. 3. Figs. 5 & 6, The products of
combustion are conducted from the fire box a, and combustion chamber b, up
the tubes, (in the direction indicated by the arrows) to the smoke box j, from
which they pass down the outside tubes r, to the bottom smoke box s, and on
'to the chimney k.
The upper smoke box casing is lined with fire brick j¹.
I do not confine myself to the exact construction of parts shewn, which may
be varied to suit requirements without departing from my invention.
Having now particularly described and ascertained the nature of
my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. In a stream generator, the combination of a vertical corrugated, or ribbed
flue, or fire box, with a combustion chamber of smaller diameter, either with or
without cross tubes, and surrounded by vertical tubes enclosed by a shell and
smoke box, substantially as described.
2. In a steam generator, the combination of a vertical corrugated, or ribbed
flue, or fire box, with a combustion chamber of smaller diameter, either with or
without cross tubes, and surrounded by tubes arranged in an inclined position,
enclosed by a tapered shell, with smoke box, substantially as described.
3.. In a steam generator, the combination of a vertical corrugated, or ribbed flue,

page_text: or fire box, with a combustion chamber of smaller diameter, either with or without
cross tubes, and surrounded by vertical tubes communicating with an upper,
and lower smoke box, and enclosed by a shell, substantially as described.
4. The improved constructions and arrangements of steam generators, sub-
stantially as described, and illustrated, by the accompanying drawings Figs. 1.
to 6.
