PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Heating Feed Water for Steam
Boilers and for other Purposes.
I, JOHN KIRKALDY, of 40 West India Dock Road, in the County of Middlesex,
Engineer, do hereby declare the nature of this invention to be as follows:-
The object of my invention is mainly to construct a cheap and efficient heater for
heating the feed water for steam boilers and for other such like purposes.
The heater I construct of a cylindrical casing with a flat surface on one side at one
end and a corresponding flat surface on the opposite side at the other end. Within
the casing is an assemblage of parallel tubes these are bent at each end and the ends
are passed through and secured in holes bored through the two flat surfaces. The
tubes may be attached to these two flat surfaces or tube plates by nuts on each side of
the plates or be expanded into the holes in the plates or be flanged and secured by nuts
or be secured in other convenient way. A hollow cover is secured to the exterior of
each tube plate one serves as an inlet by which fluid passes to the tubes the other
as an outlet. The ends of the cylinders are closed by covers and an inlet pipe is led
off from the cylinder near one end and an outlet pipe from near the other end.
The heater can be worked either by exhaust or live steam.
The steam may
be passed through the pipes and the water to be heated be passed through the
cylinder or the water may be passed through the pipes and the steam through the
cylinder.
When the water is passed through the cylinder the lower portion of the cylinder
would form a mud box from which sediment could from time to time be removed
by removing the bottom end cover and the upper portion would form an air
receptacle from which air could be from time to time drawn off by opening a cock
fitted to the top cover.
In place of the parallel tubes of the apparatus being formed with a bend at cach
end as above described they might be formed with a bend at one end only in which
case one end of each tube would be secured to a flat tube plate placed across one end
of the cylinder.

Improvements in Apparatus for Heating Feed Water for Steam
Boilers and for other Purposes.
J, John Kirkaldy, of 40 West India Dock Road, in the County of Middlesex,
Engineer, do hereby declare the nature of this invention and in what manner the same
is to he performed to be particularly described and ascertained in and by the following
statement:-
The object of my invention is mainly to construct a cheap and efficient heater for
heating the feed water for steam boilers and for other such like purposes
The heater I construct of a cylindrical casing with a flat surface on one side at one
end and a corresponding flat surface on the opposite side at the other end. Within
the casing is an assemblage of parallel tubes these are bent at each end and the ends
are passed through and secured in holes hored through the two flat surfaces. The
tubes may be attached to these two flat surfaces or tube plates by nuts on each side of
the plates or be expanded into the holes in the plates or be flanged and secured by
nuts or be secured in other convenient way. A hollow cover is secured to the
D

page_text: exterior of each tube plate one serves as an inlet by which fluid passes to the tubes
the other as an outlet. The ends of the cylinders are closed by covers and an
inlet pipe is led off from the cylinder near one end and an outlet pipe from near
the other end.
The heater can be worked either by exhaust or live steam. The steam may be
passed through the pipes and the water to be heated be passed through the
cylinder or the water may be passed through the pipes and the steam through
the cylinder.
When the water is passed through the cylinder the lower portion of the cylinder
would form a mud box from which sludge and sediment could from time to time be
removed by opening a sludge valve fitted for that purpose or by removing the
bottom end cover and the upper portion would form an air receptacle from
which air could be from time to time drawn off by opening a cock fitted to the
top cover.
In place of the parallel tubes of the apparatus being formed with a bend at each
end as above described they might be formed with a bend at one end only in which
case one end of each tube would be secured to a flat tube plate placed across one
end of the cylinder.
Figure 1 is a vertical section and Figure 2 a plan of apparatus constructed as
above described. Figure 3 is a side elevation partly in section on a smaller scale of
similar apparatus..
A is the outer casing-A' a flat surface on one side at the top of the casing and A²
a flat surface on the opposite side at the bottom of the casing-B B are parallel tubes
curved at each end to bring their ends into a horizontal position and allow of their
being passed through holes bored through the flat surfaces A'A². In Figure 1 they
are shewn as being secured to these flat plates by nuts screwed on to them on each
side of the plate but as above stated they might be secured in other suitable ways.
A³ A are hollow covers secured to the exterior of the plates A' A². The upper one
serves as an inlet for exhaust steam-the other serves as an exhaust outlet. A³ is the
top cover of the casing. C is a feed inlet for water from the feed pump and D the
feed outlet to boilers. Ein Figure 1 is a sludge door at the bottom of the casing
and F a drain cock carried by this door-or the sludge door E and drain cock F
might be at the sides of the lower part of the casing as shewn at Figure 3. The top
cover may as is also shewn in Figure 3 carry a relief valve G and small air cock or it
may simply carry a small air cock as shewn in figure 1. H in Figure 3 is a scum
valve and I is a cock by which soda solution can be introduced. J is a tube for
conveying away any water condensed in the tubes.
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. An apparatus for heating feed water and for other purposes consisting of a
cylindrical casing with a number of parallel tubes passing through it and curved at
their ends so as to pass into and be held in holes forined in flat surfaces at the sides of
the casing near the two ends and with hollow covers over the exterior of the flat
surfaces one for admitting fluid to the tubes the other for an outlet from the tubes
and with an inlet for fluid near one end of the casing and an outlet near the
other end.
2. The construction of apparatus for heating feed water for steam boilers and for
other purposes substantially as herein before described.
