PROVISIONAL SPECIFICATION.
Steam Generators for Marine and other Purposes.
I, TIMOTHY JOHN SULLIVAN, Boiler-maker, 15 Fourth Street Wallsend-on-
Tyne Northumberland do hereby declare the nature of this invention to be as
follows:
The object of my invention is to provide a water heater and steam generator
It designed
which is very efficient in rapidly heating water and raising steam.
for great strength, thus making it especially adapted for marine and other purposes
Its length
where a very high pressure is required. It is simple in construction.
from end to end may be extended so as to place furnaces at both ends, and the
whole arrangement may be repeated from the sides and top, so as to make it any
size required, (without enlarging its surfaces and thus decreasing the strength of
the boiler).
It is easily cleaned and repaired, and can be entirely machine rivetted.
In the construction I provide tube-plates, angle shaped in section, which are
placed so that when the tubes are fixed into the holes made for them in their
surfaces, they are connected, forming in section an X cross, or X crosses if the
arrangement is repeated as herebefore stated. Plates. bent to form segments of
circles are fixed to the edges of the tube-plates, enclosing the extremities of the
X cross shape formed by the tube-plates and the nests of tubes. The ends of the
angle shaped tube-plates and the segments of cylinders are enclosed by plates made
to fit them.
Between the bottom segments of cylinders and below the inverted V shaped
tube-plate, the furnace is arranged. The other spaces between the exterior of the
tube-plates and the segments of cylinders are enclosed by a casing (protected by
firebricks or other equivalent material,) and form combustion-chambers or smoke-
boxes.
The products of combustion pass from the furnaces through the inclined tubes
into the side chambers and therefrom through the upper nests of tubes and into the
smoke-box and chimney.
The segments of cylinders can be made in such sizes as may best suit the purpose
for which the boiler is intended. Those at the bottom may be small, and the
others large when more water or steam space is necessary? Or a cylindrical steam-
receiver, or dome, may be fixed to the top segments by necks in the ordinary way.
Another way is to dispense with the top segments and connect the tube-plates by
arched plates, one connecting the top tube-plate, and the other extending over
from the top edges of the side tube-plates. The bottom segments may also be
done away with, and the tube-plates connected by curved plates extending from
one nest of tubes to the other, passing under the furnace and allowing the water to
circulate round the bottom of the boiler. The ends of the boiler are substantially
stayed, and the flat tube-plates are stayed by the tubes. Manholes are arranged
in the ends for easy access to the interior of the boiler.

Steam Generators for Marine and other Purposes.
I TIMOTHY JOHN SULLIVAN 21 Ann Street. Heaton Newcastle on Tyne
Northumberland Boilermaker 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 relates to a steam generator or water heater which is very efficient
in rapidly heating the water and raising steam, it is light, strong, and simple in
construction, easily cleaned and repaired, and can be entirely machine riveted.
Steam boilers constructed according to my invention may be applied to marine
and such purposes where large boilers are required without greatly increasing the
thickness of plate.
I will now describe my invention with reference to the accompanying drawings.
Figure 1. which is an end view and half cross section.
Figure 2. is a half elevation showing fire-tubes, and half elevation showing water
tubes at right angles to one another along the line w. w.
Figures 3-4. are sectional elevations at right angles to each other, through the
line x. x. showing arrangement for two or more furnaces, with steam receiver
or dome.
Figures 5-6. are sectional elevations at right angles along the line y. y. and
Figure 7. is a modification in the arrangement for making the boiler in pieces for
sectional purposes.
In Figures 1-2. I provide tube-plates angle-shaped with inclined flat surfaces
parallel to each other, and water-space between forming an X shaped cross, the
angled recesses in which form at the bottom the furnace or fire-box at a the side
combustion chamber, at 6 and the uptake to the chimney at c the extremities of
the flats at the outer ends of the cross are enclosed by segments of cylinders e,
which are bent around to meet the tube-plates d, these angle shaped tube-plates
and segments of cylinders, (which may be of any required length) are enclosed by
the boiler ends h, thus forming the shell or skin of the boiler. The hot gases are
caused to pass from the furnace a through the nests of tubes a¹ into the combustion
chambers b and through the upper nests of tubes a into the uptake c. The side
chambers bare enclosed at j doors are provided, and there may be water tubes f
placed in the combustion chambers which causes a circulation of water and also
protects the walls from the excess of heat.
In the part end view of Figure 1 which shows the front of the boiler, I provide
man-holes for easy access between the nests of tubes and into the segments of
cylinders.
Figures 3-4 are a cross section and a sectional elevation on lines x. x.
This arrangement shows (a form of boiler extended from the cross shape as
Figure 1 into crosses when the arrangement is repeated).
By means of the square combustion-chamber n and plates (m) bent to meet the
flats of the angled tube-plates. It will thus be seen that there can be any required
number of furnaces as a a with nests of tubes to correspond. The segments of
cylinders can be made in such sizes as may best suit the purpose for which the
boiler is intended, those at the bottom may be small, and the others large when
more water or steam space is required. Or a cylindrical steam receiver or dome s
may be fixed to the top segments connected by necks at r in the ordinary way.
Figures 5-6 show another way in which I dispense with the top segments (as
shown in Figures 1-3-7) and connect the angle-shaped tube-plates by arched
plate which form the top chamber the waste gases passing out through the
uptake o or the uptake may be dispensed with and the waste gases to pass out from
the end or ends of the top chamber c. Another arched plate is extended over
from the top edges of the side combustion chambers & forming the top outside skin
v

page_text: or shell of the boiler. The bottom segments may also be done away with and
connected as above by curved plates enclosing the bottom nests of tubes and
arranging an internal furnace a with water space around its bottom. The curved
plate connecting the side chambers thus causing the bottom outside skin or
shell. The products of combustion pass through the fire-tubes a to the chambers b
and travel on to the uptake c as described in Figure 1.
Figure 7 is a modification in which flat tube-plates d about parallel to each
other with water space between are connected at their inner edges by curved
plates t the outer edges being enclosed by segments of cylinders e as hereinbefore
described, and form a skin or shell enclosing a nest of fire-tubes passing through
and staying the flat surfaces d together. The curved-plates t may be connected
together by means of rows of short water-tubes g which may be screwed or other-
wise into the skin of the inner surface t.
The boiler is encased the same and the hot gases are caused to travel as herein
before described in Figure 1.
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. A steam generator in which the combination of angled-shaped recesses with
flat tube-plates at or about right angles to each other are arranged to form a
water-space in cross section an X cross or crosses and to the extremities of the
flats at the outer ends of which cross or crosses are enclosed by segments of
cylinders causing to form the skin or shell of the boiler substantially as hereto-
before described with reference to the accompanying drawings.
2. A steam generator in which the combination of angle-shaped tube-plates with
water-space between the flat surfaces, which are connected and strengthened by
stay fire-tubes at the root or heel to compensate for the segment of cylinder which
is necessarily cut away substantially as herein-before set forth.
3. The combination in steam generators or boilers in which X shaped water
spaces are continued so as to provide two or more furnaces with nests of tubes and
combustion-chambers to correspond substantially in the manner described with
reference to the accompanying drawings in Figures 3-4.
4. A steam generator in which nests of tubes are enclosed by angled-shaped
tube-plates connected to curved plates extending from one nest of tubes to the other
passing under the furnace allowing a water-space around the bottom and the upper
tube-plates being enclosed by arched plates one connecting the top chamber and
the other extending over from the upper flats of the side tube-plates which are
enclosed by doors substantially as herebefore described in Figures 5-6 of the
accompanying drawings.
5. A steam generator in which flat tube-plates about parallel to each other with
water space between are connected by curved plates which form a skin or shell
enclosing a nest of fire-tubes which are fixed into the flat surfaces, and the shells
may be connected together by means of short fixture or removing water-tubes to
form the arrangement of an X cross of which the angled enclined recesses enclose
a furnace at the bottom and side chambers and uptake substantially as set forth in
Figure 5 of the accompanying drawings.
