Improvements in Boilers.
I, FRED ADELBERT GARDINER, residing at Dedham, in the County of Norfolk, in
the State of Massachusetts, United States of America, Mechanical Engineer, do
hereby declare the nature of this invention to be as follows:-
This invention relates to steam generators, and the object thereof is to provide
an improved boiler or steam generator which is simple in construction and
operation, and which is especially adapted for use as a steam generator for marine
engines, and also for use wherever it is necessary to provide great power with a
minimum amount of fuel, and where but little floor space is available.
In the practice of my invention, I provide a steam generator which comprises
two bottom parallel water drums or pipes which are connected at their front ends
by a cross pipe which is provided with a water supply pipe, and the water drums
or pipes are each provided at their rear ends with a discharge or blow off
pipe.
Connected with each of the water drums or pipes is a plurality of vertical
pipes, any desired number of which may be employed, and these vertical pipes are
connected with the water drums or pipes by means of short extensions.
Any desired number of the vertical side pipes may be employed, and these
pipes are placed in communication with transverse separating drums, any desired
number of which may also be employed, and said separating drums are placed
transversely of the bottom water drums or pipes, and said separating drums are
also in communication with the vertical pipes by means of supplemental pipes
which are preferably much smaller than the vertical side pipes, and each of these
separating drums is in communication with three of the vertical side pipes at one
end, and with two of said vertical side pipes at the other end, this arrangement being
alternate, and each of the vertical side pipes is provided with a plurality of smaller
auxiliary pipes which also communicate with the separating drum connected
therewith, and these auxiliary pipes are provided with the vertical side pipes, and
with vertical portions which communicate with the separating drum, said auxiliary
pipes being provided with a single bend or elbow.
The separate transverse drums with which the vertical side pipes and the
auxiliary pipes communicate, are each placed in communication with a dry steam
drum which is arranged thereover, and the steam for use is taken from the dry
steam drum in the usual manner, and as thus constructed, the entire space above
the fire box is filled with the auxiliary steam pipes.
The water passes into the bottom water diums or pipes, and up into the vertical
side pipes, and into the auxiliary pipes, and said pipes being filled to the required
point, when the heat is applied thereto, and there will be a rapid circulation through
the auxiliary pipes, the water passing through the lower tiers, or the horizontal
branches thereof, up through the vertical branches of said tiers into the separating
drums, and back into the vertical side pipes through the extensions by means of
which said side pipes are connected with said separating drums.

page_text: The separating drums also serve to separate the dry steam from the saturated
steam, and the water of condensation passes back into the pipes, while the dry
steam passes into the dry steam drum which, is situated over the separating
drums.
My improved boiler or steam generator is more compact than any other boiler
now in use, and by means thereof, greater power inay be obtained by a consumption
of a minimum supply of fuel, than with any other boiler or steam generator as now
constructed, and it will also be apparent that my improved boiler is particularly
adapted for use where there is but little floor space available, and said boiler or
generator may be constructed of any desired material, and the separate parts
thereof, connected in any preferred manner.

COMPLETE SPECIFICATION.
Improvements in Boilers.
I, FRED ADELBERT GARDINER, residing at Dedham, in the County of Norfolk, and
State of Massachusetts, United States of America, 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 relates to steam generators, and the object thereof is to provide
an improved boiler or steam generator which is simple in construction and operation,
and which is especially adapted for use as a steam generator for marine engines, and
also for use wherever it is necessary to provide great power with a minimum amount
of fuel, and where but little floor space is available.
The invention is fully disclosed in the following specification of which the
accompanying drawing forms a part, in which the separate parts of my improvement
are designated by the same numinerals of reference throughout the several views, and
in which
Fig. 1, is a front view of my improved boiler or steam generator;
Fig. 2, a side view thereof; and,
Fig. 3, a section on the line 3, 3, of Figs. 1 and 2.
In the practice of my invention I provide a steam generator which comprises
two bottoin parallel water drums or pipes 5, which are connected at their front
ends by a cross pipe 6, which is provided with a water supply pipe 7, and the water
drums or pipes 5, are each provided at their rear ends with a discharge pipe 8,
which in practice, is provided with an ordinary valve, and these pipes 8, constitute
the usual blow off pipes.
Connected with each of the water drums or pipes 5, is a plurality of vertical
pipes 9, any desired number of which may be employed, and these pipes 9, are
connected with the water drums or pipes 5, by means of short extensions 10.
For the purposes of illustration, I have shown twelve of the vertical pipes 9, on
one side, and thirteen on the other, and these pipes are placed in communication
with transverse separating druins 11, any desired number of which may be employed,
said separating drums being placed transversely to the water drums or pipes 5, and
said separating drums are in communication with the vertical pipes 9, by means
of supplemental pipes 12, which are preferably smaller than the pipes 9, and each

page_text: of these separate drums is in communication with three of the pipes 9, at one end
with two of said pipes at the opposite end, this arrangement being alternate as
shown in Fig. 2, and each of the pipes 9, is provided with a plurality of auxiliary
pipes 13, which also communicate with the separating drum 11, connected therewith,
the arrangement of these auxiliary pipes 13, being clearly shown in Figs. 1 and 3,
said pipes being provided with one bend or elbow as shown at 14, whereby it is
provided with one horizontal and one vertical branch, the horizontal branch
communicating with the pipe 9, and the vertical branch with the corresponding
separating drum 11.
The separating drums 11, are each placed in communication with a dry steam
drum 15, by means of pipes 16, and the steam for use is taken from the drum 15,
in the usual manner.
As thus constructed it will be seen that the entire space above the fire box which
in practice, is located at 17, in Fig. 1, is filled with the auxiliary steam pipes 13.
The water passes into the water drums or pipes 5, through the pipe 6, and up-into
the pipes 9, and into the auxiliary pipes 13, and said pipes are filled to
the required point, and when these pipes are heated, there will be a
very rapid circulation through the auxiliary pipes, the water passing through
the lower tiers or the horizontal branches thereof, up through the vertical
branches of said tiers into the separating drums 11, and back through
the pipes 12 into the pipes 9. The drums 11 serve also to separate the dry
steam from the saturated steam, and the water of condensation, and the latter passes
back into the pipes while the dry steam passes into the steam drum 15.
My invention is not limited to the material of which the various parts thereof
are made, but I prefer wrought iron or steel, and the connections between the-
various parts thereof, may be made in any desired manner.
My improved boiler or steam generator is more compact than any other boiler
now in use, and by means thereof, greater power may be obtained by the consumption
of a minimum supply of fuel than with any other boiler or steam generator as
now constructed.
It will also be apparent that less Boor space is necessary, and by providing the
separate drums 11, and 15, I am enabled to effectually separate the dry from the
saturated steain, and this arrangement also constitutes one of the chief features
of 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 I claim is :-
1. A steam generator comprising two horizontal water drums or pipes with each
of which is connected a plurality of vertical pipes, said vertical pipes being
connected with transverse separating drums as described, each of said vertical pipes
being also provided with a plurality of horizontal and vertical auxiliary pipes which
are also connected with said drums, said separating drums being also in communication
with a steam drum which is arranged thereover, substantially as shown and
described.
