I, CHARLES DAVID JERMYN of the City of Hamilton, County of Wentworth
and Province of Ontario Canada, Book-keeper, 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:-
The object of my invention is to devise a simple and effective water tube
boiler, in which a large beating surface is secured, and in which all tubes are
vertical and are readily accessible for repairs or cleaning, and it consists,
essentially in constructing the heating surface of the boiler in sections composed
of vertical tubes connecting horizontal water pipes communicating with the
vertical drum or separator located in the combustion chamber of the boiler, and
in such other details of construction, as hereinafter more specifically described and
then definitely claimed.
Figure 1 is a perspective view of a boiler constructed in accordance with my
invention.
Figure 2 is a longitudinal vertical section of the same.
Figure 3 is a perspective skeleton view showing the arrangement of the pipes
and tubes.
In the drawings like letters of reference indicate corresponding parts in the
different figures.
A is the vertical drum or separator located preferably in the combustion
chamber T of the boiler. Horizontal distributing pipes B and C, are connected
with the interior of the separator, at its front side (see Figures 2 and 3).
D is a horizontal distributing pipe connected with the interior of the separator
at its rear side, close to the bottom.
E are pipes detachably connected to the front of the distributing pipe B by
right and left hand threaded nipples M.
Fare pipes similarly connected to the distributing pipe C. Both of these
series of pipes touch one another so as to form horizontal air-tight partitions in
the boiler. Each of these pipes is provided at its outer end with a screw plug O',
the removal of which leaves the interior of the tube open for the insertion of a
cleaning rod. All other horizontal pipes in the boiler are similarly provided with
these screw-plugs so that the boiler may be completely cleaned without removing
any portion of the casing.
I and J are vertical tubes, the upper end of the tube I being detachably
connected by a right and left hand threaded nipple L to the pipe E the lower end
of the tube J being connected to the corresponding lower pipe F. The free end of
the pipe Jis connected with the pipe near its upper end by an L-shaped
coupling K and the lower end of the pipe I is similarly connected to the lower
end of the pipe J. By using double vertical pipes thus connected, the heating
surface of the boiler is also doubled and from the peculiar method of connection,
a cleaning rod may be inserted from end to end of the tubes I and J, a small
plug O, see Fig. 2, being provided in each L-coupling K. A series of these
tubes I and J connect each pair of pipes E and F. Each series of pipes together
with the pipes E and F which it connects, will be hereinafter referred to as a
tube section P.
On each side of the fire-box U, a tube section Q is located, the horizontal
pipes G and H, of which are connected respectively with the horizontal dis-
tributing pipes C and D. A series of tubes I and J connect the horizontal

page_text: pipes G and H and thus form a side lining to the fire-box, the top of which is
formed by the pipes F, and the bottom by the grate V.
S is a series of double pipes connecting the distributing pipes D and B. The
pipes of this series are similarly arranged to the tubes I and J with the exception
that as the distributing pipe D, is at the rear of the combustion chamber T and
the distributing pipe B, at the front, the tubes of the series S are bent at right
angles to enter the rear side of the distributing pipe B.
O are two sections connecting the distributing pipes B, and C, so as to form a
side lining to the combustion chamber T (see Fig. 2). These tube sections are
similar in arrangement to the tube sections P or Q
a is the steam pipe connected with the upper end of the separator A. This
pipe is connected by a Y-joint b to two coils c and d located above the pipes E.
These coils are connected by a pipe e to which the continuation of the pipe a is
connected by a T-joint.
fis a feed water inlet. g is a combined steam and water gauge connected by
the pipe with the separator A, above the water level, and by the pipe i to the
pipe H (see Figs. 1 and 3).
R is the casing; this casing is shaped and connected as shown so that the
heated gases from the fire-box are directed from the combustion chamber forward
through the interstices between the tubes of the section P, and then up and
over the top of the pipes E and past superheating coils c and d to the
smoke-stack j.
k is the front door of the smoke-box which may be provided with any suitable
device to hold it closed. Suitable doors are also provided as shown for the
fire-box.
l is a portion of the casing shown in dotted lines in Fig. 2 which forms the top
of the combustion chamber T, and prevents the heated gases therein from
descending directly to the smoke stack. m is a plate supporting the tube sections P
on the tube sections Q.1
Having described the construction of my boiler and the course of the heated
gases therein, I will briefly describe the circulation of the water therein.
The feed water enters the separator by the pipe f, below the level of the
distributing pipe B. The cold water descends and enters the lower distributing
pipes C and D.
From the distributing pipe D, the water enters the tube sections
and ascends through them to the distributing pipe C. There it mingles with
a fresh supply of water from the separator and passes through the tube sections P
and into the distributing pipe B which returns it to the upper part of the
separator A. This circulation is continuous, the steam as it forms, collecting
in the upper part of the separator, the water level being generally somewhat
below the level of the pipes. E. As all the heating tubes in the boiler are
vertical a very rapid circulation is ensured. As the separator A is vertical
and also forms the connection between the upper and lower pipes of the tube
sections, separate down-comers are dispensed with, effecting a considerable
saving in weight and simplifying the construction. The separator A being.
vertical its steam space may be considerably enlarged by increasing its length
without the necessity as in a horizontal separator of greatly increasing the
diameter.
If desired, a cross-drum could be connected with the upper end of the
separator so as to enlarge the steam space, or if desired two separators could be
used at opposite ends of the combustion chamber. The combustion chamber
itself, it will be observed is of considerable size and thus ensures the proper com-
bination of the gases from the fuel with the oxygen of the atmospheric air admitted
for the purposes of combustion.
It will be seen that all parts of the casing liable to be exposed to the action of
the fire or heated gases, are lined with tubes, thus increasing the heating surface
and preserving the casing from the destructive action of the fire.
As the upper and lower pipes of the sections P are detachably connected to the

page_text: horizontal distributing pipes B and C any section desired may be removed
without disturbing the casing for the cleaning or repairing of any portion
thereof, the lower pipes being disconnected by entering the fire-box and the
upper ones through the lid n.
The vertical tubes of the sections Q and O may be removed through the fire-
box while the tubes S are accessible for removal through the lid n.
Having now particularly described and ascertained the nature of the said
invention and in what mauner the same is to be performed I declare that what I
