1, GEORGE KINGSLEY residing at the corner of Smith and Liberty Streets, Lowell
in the State of Massachusetts, United States of America, Engineer, do hereby declare
the nature of this invention to be as follows:-
:-
My Invention is in the nature of certain improvements upon the Steam Boiler for
which Letters Patent of the United States of America were granted to me July 31st
1883, No. 282,330. The outer shell of the boiler is oval form in cross section, and
the inner shell is of corresponding form at the lower part but has a flat crown sheet
with pendent tubes extending down into the fire space, braces extending from the
crown sheet upwardly to the outer shell. The water occupies a position between the
outer shell, and the inner shell, and covers the crown sheet a few inches, and descends
into the pendent tubes which give great steaming surface. As so far described, the
construction does not differ materially from that shewn in my previous Patent. The
boiler is set, however, with a flue space on each side between the outer shell and the
brickwork or casing and with a fue beneath the boiler. The flues at the sides
communicate at the rear end of the boiler with the fire chamber, and at the front ends
these flues communicate with the flue under the boiler side and bottom, the flues
being separated by horizontal partitions on each side which extend to within about
four feet of the front end of the boiler. The flue under the boiler at its rear
end communicates with a chimney or smoke stack. In the flue beneath the
boiler is placed a feed water coil and purifier, which has an inlet valve at the
rear and a bend with a valve in it at its front end which enters the boiler.
This coil not only serves as a feed water heater, but it purifies the water by
allowing the sediment to deposit therein and for cleaning it out, a second valve
is provided at the rear of the boiler. Now, as the products of combustion pass
from the fire chamber, they enter the side flues at the rear on each side, then
pass to the front, heating the outside of the shell of the boiler, then descending
around the front ends of the partitions, they enter the flue below the boiler, where.
they heat the lower surface of the boiler and also the feed water coil, and thence
pass outwardly to the rear into the smoke stack. In order to throw the hot-air

page_text: currents and flames well up into the pendent tubes in the fire chamber, I put
two rows of loose brick in the open space behind the bridge wall beneath the
long tubes, setting them up flush with the bottoms of the long tubes. The first
row of bricks, I place about half way between the bridge wall and the back end
of the boiler, and the second row, I place near the back end. These bricks get
red hot and set fire to all of the gases and force them with all hot air up among
the tubes, which is an improvement. In the place of these brick deflectors, I may
use removable deflectors, which are of a semi-circular shape to correspond with
the bottom of the fire chamber at the rear of the bridge wall, and have projecting
feet or flanges at the bottoms whereby they stand erect upon their own bases by
simply being placed in position. Two or more of these deflectors set in the fire
chamber, as shewn, throw the flames and hot currents up among the drop tubes
thereby greatly increasing the steaming capacity of these tubes and securing an
economy in fuel. These deflectors may be readily lifted out or turned around-to
permit the bottom of the fire chamber to be cleaned. A dry steam chamber is
connected with the top of the boiler by pipes. In these pipes are arranged a number
of braces, in addition to the usual braces, which braces are riveted to the inner
periphery of the pipes and connect with the crown sheet. This not only makes a
strong connection for bracing the crown sheet, but also stiffens the connection of
the pipes.

page_text: 1 GEORGE KINGSLEY residing at the corner of Smith and Liberty Streets, Lowell
in the State of Massachusetts, United States of America, 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 invention is in the nature of certain improvements upon the steam boiler for
which Letters Patent of the United States of America were granted to me July 31st
1883, No. 282,330, and it consists in the peculiar construction and arrangement of
parts, which I will now proceed to describe with reference to the accompanying
drawings forming part of this specification wherein―
Figure 1 is a vertical longitudinal section.
Figure 2 a vertical transverse section; and figure 3 is a horizontal section through
line xx of figure 2.
Figure 4 is a side view in detail of one form of deflector for the hot currents in
the fire chamber.
In these figures A represents the outer shell, B the inner shell having a flat crown
sheet with pendent tubes C extending down into the fire space, and E are braces
extending from the crown sheet upwardly to the outer shell.
The water occupies a position between the outer shell A and the inner shell B and
covers the crown sheet a few inches, and descends into the pendent tubes which give
great steaming surface. As so far described, the construction does not differ materially
from that shown in my previous Patent. The boiler is set, however, with a flue
space I on each side between the outer shell and the brick-work or casing and with a
flue J beneath the boiler. The flues I at the sides communicate at the rear end of the
boiler with the fire chamber, and at the front ends these flues I communicate with the
flue J under the boiler, the flues I and J being separated by horizontal partitions H
on each side which extend to within about four feet of the front end of the boiler.
The flue J under the boiler at its rear end communicates with a chimney or smoke
stack L.
In the flue J beneath the boiler is placed a feed water coil and purifier G, which
has an inlet valve G' at the rear, and a bend F with a valve in it at its front end
which enters the boiler. This coil not only serves as a feed water heater, but it
purifies the water by allowing the sediment to deposit therein, and for cleaning it out,
a second valve G' is provided at the rear of the boiler, see Figure 3.
Now as the products of combustion pass from the fire chamber, they enter the side
flues II at the rear on each side, then pass to the front, heating the outside of the
shell of the boiler, then descending around the front ends of the partitions H they
enter the flue J below the boiler, where they heat the lower surface of the boiler and
also the feed water coil G and thence pass outwardly to the rear into the smoke
stack L.

page_text: In order to throw the hot air currents and flames well up into the pendent tubes
in the fire chamber I put two rows. M M of loose brick in the open space behind the
bridge wall beneath the long tubes, setting them up flush with the bottoms of the
long tubes. The first row of bricks I place about half way between the bridge wall
and the back end of the boiler, and the second row I place near the back end.
These bricks get red hot and set fire to all of the gases and force them with all hot
air up among the tubes which is an improvement. In the place of these brick
deflectors, I may use removable deflectors M¹ (figure 4) which are of a semi-circular
shape to correspond with the bottom of the fire chamber at the rear of the bridge wall,
and have projecting feet or flanges at the bottoms whereby they stand erect upon
their own bases by simply being placed in position. Two or more of these deflectors
set in the fire chamber as shown throw the flames and hot currents up among the
drop tubes thereby greatly increasing the steaming capacity of these tubes and
securing an economy in fuel. These deflectors may be readily lifted out or turned
around to permit the bottom of the fire chamber to be cleaned. N is a dry steam
chamber connecting with the top of the boiler by pipes P. In these pipes are.
arranged a number of braces O in addition to the usual braces, which braces O are
rivetted to the inner periphery of the pipes, and connect with the crown sheet.
This not only makes a strong connection for bracing the crown sheet but also stiffens
the connections of the pipes P. K is a blow-off pipe with valve for removing
sediment from the bottom of the boiler.
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. The combination with the outer casing, of the boiler composed of an outer shell
and inner shell with flattened crown piece, and pendent tubes communicating with
the water space and descending into the fire space of the inner shell, horizontal
partitions H H dividing the space between the outer shell and the outer casing into
the side flue spaces II and bottom flue space J, the rear ends of the side flues being
in communication with the fire chamber, and their front ends communicating with
the bottom flue, and the feed water coil G arranged in the bottom flue substantially
as and for the purpose described.
2. The combination of the outer casing, the boiler composed of an outer shell
and an inner shell with flattened crown piece, and pendent tubes communicating
with the water space and descending into the fire space of the inner shell, the
said boiler being set in the casing so as to form a partition, separating the space
between the boiler and casing into side flue spaces II and bottom flue J, the
rear ends of the side flues being in open communication with the rear end of the
fire chamber in the boiler, and the side flues I and bottom flue J being in open
communication with each other at the front end, substantially as and for the purpose
described.
3. The combination with the outer shell A having pipes P connecting with a dry
steam chamber, the inner shell having flattened crown sheet with pendent tubes, and
braces communicating with said crown sheet and extended up into and fastened to
the inner periphery of the pipes P, substantially as and for the purpose described.
Dated this 28th day of June 1887.
