IMPROVE- MENTS IN SURFACE CONDENSERS AND HEATERS
Year: 1884

page_text: I JOHN KIRKALDY of 40 West India Dock Road Poplar in the County of
Middlesex Engineer do hereby declare the nature of my invention for "IMPROVE-
MENTS IN SURFACE CONDENSERS AND HEATERS" to be as follows:-
In the specification of a former Patent granted to me on the 3rd day of May
No 7200 is described a surface condenser in which steam to be condensed is passed
through a series of coiled pipes enclosed in a casing through which a current of
water is maintained. The stream of water was introduced into one end of the
casing through a central pipe. According to my present invention in order more
effectually to cause an equal flow of water to be brought into contact with each of
the several coils of pipe I place within the casing at a short distance from the end
at which water is introduced into it another plate in which are holes through
which straight end pieces at the end of each coil pass. The holes in the plate are
made larger than the tubes so that there may be a free passage for water between
them.
The water supply is introduced into the space between the two plates either
through a central supply pipe or a supply pipe at one side and passing from this
space through the holes above mentioned produces a uniform flow of water past
each of the coils contained within the casing.
Apparatus constructed as above can be used either as a condenser or cooler or as
a heater in either case the fluid to be cooled or heated might either be passed
through the coils of pipe or through the casing surrounding them. The coils also
may either be made alternately right and left handed so as to interlock one with the
other or they may simply be placed side by side and parallel with one another.

page_text: I, JOHN KIRKALDY of 40 West India Dock Road, Poplar in the County of
Middlesex, Engineer do hereby declare the nature of my invention for "IMPROVE-
" and in what manner the same is
to be performed to be particularly described and ascertained in and by the following
Statement:-
MENTS IN SURFACE CONDENSERS AND HEATERS
In the specification of a former Patent granted to me on the 3rd day of May
No 7200 is described a surface condenser in which steam to be condensed is passed
through a series of coiled pipes enclosed in a casing through which a current of
water is maintained. The stream of water was introduced into one end of the
casing through a central pipe.
According to my present invention in order more effectually to cause an equal
flow of water to be brought into contact with each of the several coils of pipe
I place within the casing at a short distance from the end at which water is
introduced into it another plate in which are holes through which straight end pieces
at the end of each coil pass. The holes in the plate are made larger than the tubes
so that there may be a free passage for water between them.
The water supply is introduced into the space between the two plates either
through a central supply pipe or a supply pipe at one side and passing from this
space through the holes above mentioned produces a uniform flow of water past
each of the coils contained within the casing.
Apparatus constructed as above can be used either as a condenser or cooler or as
a heater in either case the fluid to be cooled or heated might either be passed
through the coils of pipe or through the casing surrounding them. The coils also
may either be made alternately right and left handed so as to interlock one with the
other or they may simply be placed side by side and parallel with one another.
In the drawing hereunto annexed I have shewn a surface condenser or heater
constructed as above described.
Figure 1 is a side elevation with one-half in section of a condenser constructed
as above described, and suitable for being used as the surface condenser of a marine
or other steam engine. Figure 2 is a part plan view one-half in section and Figure 3
is a plan also with one-half in section the section being taken at a lower level than
in Figure 2.
In these figures A is the outer casing B a tube plate across the top, C a tube
plate across the bottom. Dan upper cover above the top tube plate. E a bottom
cover below the bottom tube plate. F are a series of tubular coils with which the
whole interior of the casing is occupied.-G is a plate at a short distance above the
bottom tube plate C it has holes formed through it as shewn for the lower ends of
the several tubular coils to pass through, and the holes are as above stated larger
than the diameter of the pipes which pass through them.
His the steam inlet. I I are outlets for the circulating water. J the inlet for
admitting circulating water to the space between the bottom tube plate and the
plate G above it, and K is an outlet for the condensed steam to which the air pump
suction pipe of the engine is coupled.

page_text: 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. The combination of a perforated plate G with apparatus such as is described
in the specification of the Patent granted to me on the 3rd day of May last N° 7200
substantially as described.
2. The construction of surface condensers and heaters substantially as herein
before described and illustrated in the drawing annexed.
