Improvements in and relating to Tubulous Steam Boilers.
1, ALBERT FREDERICK LOUIS REUSSNER, of No. 100 Bright Street Jersey
City, in the County of Hudson, State of New Jersey, U.S.A., Inventor, 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 contemplates certain new and useful improvements in boilers and
has for its object the production of a boiler possessing advantages in point of
simplicity, durability and inexpensiveness, and in which the steam can be readily
generated and the cold water supply is not affected by the heat or products of
combustion and all "choking" is avoided.
A further object is to provide an improved boiler in which water-backs or walls
are formed at the sides and ends of the boiler.
A further object is to provide a boiler wherein access can be readily had to the
different parts for the purpose of cleansing and in which any injured part can be
readily removed without disturbing the other parts of the boiler.
The invention consists, primarily, of a boiler having inclined tubes connected
with each other and with a steam dome by horizontal and vertical passages at each
end of the boiler.
The invention further consists of a boiler having inclined tubes, and water-backs
at the ends of the boiler into which said tubes open, and stand-pipes connected to
said water-backs.
The invention further comprises a boiler having inclined tubes, horizontally
disposed headers into which said tubes open, stand-pipes connecting the said
headers of each series and forming uptakes and downtakes, and tubes connecting
the opposite stand-pipes forming side water-backs.
The invention also comprises the details of construction, combination and
arrangement of parts, substantially as hereinafter fully set forth and particularly
pointed out in the claims.
In the accompanying drawing:
Figure 1 is a vertical longitudinal sectional view of my improved boiler with a
portion only of the enclosing casing. Figure 2 is a plan view. Figure 3 is a front
end view.
Referring to the drawing, A designates the enclosing casing; a the grate;
a¹ the fire-box; a² the ash pit; and as a curved bridge to direct the passage of the
products of combustion.
B designates a series of inclined tubes opening at their ends into two series of
horizontal headers b, b'. These tubes B are staggered, that is, each tube is located
above or below the intervening space of two tubes in the adjacent row of tubes.
The horizontal headers b, b', are extended transversely, relative to tubes B, and
are placed one upon the other, forming complete water-walls or backs at each end
of the boiler. At their ends these series of headers, b, b¹, are, respectively,
connected by nipples 2 and end-caps 63 with two sets of stand pipes C, C, the
former constituting an uptake and the latter a downtake, said latter stand-pipes
being connected at their lower ends to a mud-drum D, when desired, and at their
upper ends to a horizontal steam-drum E to which the uptake stand-pipes C are
also connected by upper steam-pipes d, and lower tubes d' extending from an upper

page_text: horizontal pipe d2 and opening into said drum at a point beneath the water-line.
e is the dry-pipe and e¹ the feed-pipe..
In order to increase the capacity of the boiler and extend the action of the
products of combustion over as great an area as practicable I form side water-
backs extending the length of the boiler. These water-backs are composed of
tubes Fopening at their ends into the stand-pipes of the up-takes and down-takes,
said tubes being placed one upon the other and forming complete walls throughout
the length of the boiler. This construction is of especial advantage in marine
boilers, but in stationary boilers these tubes F may be dispensed with and brickwork
substituted. It will also be understood that in marine boilers the mud-drum is not
required.
The stand-pipes C, C' have plug-covered hand openings f so located that access
can be readily had to one of the headers and the side tube F opening on a line
therewith. Thus the tubes and headers can be readily inspected and cleaned.
Should any of the headers or tubes be damaged such part can be readily removed
and another substituted without disturbing the remaining parts of the boiler.
In order to direct the passage of the products of combustion and to aid in
preserving the position of the longitudinal tubes the latter are preferably passed
through openings in two plates or bridges G, which cause the products of com-
bustion to travel a circuitous course. It will be observed that the heat in passing
from the boiler travels over the water-back formed by the rear series of headers
and between the two end stand-pipes. Hence the heat not striking against or
passing between the cold-water conductors. the operation of the boiler is not
impeded by banking or choking. In this way the minimum heat only approaches
near to contact with the cold-water conductors or down-takes.
The advantages of my invention are apparent to those skilled in the art to which
it appertains, and it will be specially observed that I have produced a boiler having
a maximum capacity and that the arrangement of the tubes is such that steam can
be readily generated and conveyed from the up-takes through the steam-pipes to
the drum, from which, or any point of said steam-pipes, connection may be made
for carrying away the steam. It will also be noticed that any water passing
through the up-takes will be conveyed back to the steam drum through the series
of tubes leading thereto from said up-takes, said tubes being located above and
outside the top of the casing. A boiler constructed as herein-described is efficient
in operation, is strong and durable, inexpensive and simple in construction.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. A boiler having a series of inclined tubes connected with each other and with
a steam-drum by horizontal and vertical passages at each end of the boiler,
substantially as set forth.
2. A boiler having a series of inclined tubes, headers into which said tubes open,
and two sets of stand-pipes connecting said headers in series, substantially as set
forth.
3. A boiler having a series of inclined tubes, headers into which said tubes open,
two sets of stand-pipes connecting said headers and forming up-takes and down-
takes, and the steam-drum to which said sets of stand-pipes are connected,
substantially as set forth.
4. A boiler having a series of inclined staggered tubes, horizontal headers into
which said tubes open arranged one upon the other, two sets of stand-pipes into
which said headers open at their ends, the steam-drum and connections between the
latter and said stand-pipes, substantially as set forth.
5. In a boiler, the combination with the casing, the series of tubes, and the two
sets of stand-pipes forming up-takes and down-takes, of the steam-drum, the pipes
and the series of water-tubes located outside of said casing and connecting said
up-take stand-pipes to said steam-drum, substantially as set forth.

boiler into which said tubes open, and side water-walls or backs connecting said
end water-backs and enclosing said series of tubes, substantially as set forth.
7. A boiler having a series of inclined tubes, two sets of stand-pipes, two sets of
headers, the headers of each set being arranged one upon the other and having the
said inclined tubes opening thereinto, and forming water-backs, said headers
opening at their ends into said stand-pipes, and the two series of tubes connecting the
opposite stand-pipes of said sets, the tubes of each series being arranged one upon
the other, forming side water-walls or backs, substantially as set forth.
8. The herein-described improved boiler consisting of the series of inclined

of inclined tubes connecting the opposite stand-pipes of said sets of stand-pipes, the
steam-drum to which said down-take stand-pipes are connected, the steam-pipes
and the series of tubes connecting said uptake stand-pipes to said drum, sub-
stantially as set forth.
9. A boiler having a series of longitudinally-extended tubes inclined from front
to rear, a forward upper series of transverse horizontal headers, a rearward lower
series of transverse horizontal headers, said tubes opening into said headers, cold
water being supplied to said rearward, lower series of lower headers at the ends
thereof, and deflector plates or bridges, substantially as set forth, whereby the
products of combustion are caused to pass out over the top of said rearward, lower
series of headers, as stated.
