page_text: I, JOHN MCMEEKIN, of 8 Flowerhill Street, Airdrie, Lanarkshire, Machinery
Merchant, do hereby declare the nature of this invention to be as follows:-
This invention relates to apparatus for heating water. It is specially adapted for
use in paper mills.
In carrying out my invention I construct a vertical casing or cylinder having an
inlet for exhaust or live steam at the top and an outlet for the steam at the bottom.
At a space of about two feet from the bottom a horizontal partition is fitted in the
interior of the casing and a similar partition is also fitted near the top of the casing.
Secured in these partitions are a number of vertical tubes which extend from end to
end of the casing. Cold water is supplied from a tank, located above the bevel of
the top of the casing, to the bottom of the space enclosed between the two partitions
whilst a hot water outlet is provided near the top of said space.
The exhaust steam from an engine is supplied to the top of the casing and passes
downwards through the tubes to the outlet at the lower end. In its passage the
steam heats up the water surrounding the tubes. The cold water is supplied
automatically from the tank.
Live steam of course can be used if desired.
A perforated baffle plate is preferably arranged so as to spread the steam on its
entrance into the casing.
A manhole door is provided for gaining access to the exterior of the tubes and a
manhole door is provided for gaining access to the space below the bottom partition
for the purpose of facilitating the removal or insertion of the tubes.
The invention can be adapted for heating the feed water of steam boilers.
Dated this 17th day of December 1896.

page_text: same is to be performed, to be particularly described and ascertained in and by
the following statement:-
This invention relates to apparatus for heating water. It is specially adapted
for use in paper mills, breweries, and other places where a large supply of hot water
is desired,
And in order that my said invention may be properly understood I have hereunto
appended an explanatory sheet of drawings, whereon,
Fig. 1 is a front elevation of the apparatus,
Fig. 2 is a plan.
Fig. 3 is a enlarged section of one of the tubes f¹.
Referring to the drawings whereon the same reference letters wherever repeated,
indicate the same parts.
In carrying out my invention I construct a vertical casing or cylinder a having an
inlet b for exhaust or live steam at the top and an outlet c for the steam (and) or
condensed water at the bottom. At a space of about two feet from the bottom a
horizontal partition d is fitted in the interior of the casing and a similar partition e is
also fitted near the top of the casing. Secured in these partitions are a number of
vertical tubes f which extend from end to end of the casing. Cold water is supplied
automatically from, a tank g located above the level of the top of the casing through
the pipes h, h, to the bottom of the space enclosed between the two partitions
whilst a hot water outlet pipe é is provided near the top of said space.
There is or may be connected with the casing a a circulating tank j. This tank
which is kept constantly filled with water communicates with the top of the casing a
by means of the pipe and with the bottom of the casing a by means of the
pipe A¹.
k is the hot water pipe leading off from the tank j it is provided with a shut off
cock k¹. 2 is a shut off cock on the cold water supply pipe h which is only closed
when cleaning the apparatus. is the exhaust or live steam supply pipe. m is the
steam exhaust pipe. n is a valve box with a flap or other suitable valve therein to
prevent inrush of air as the steam condenses in the pipes f. is a trap for condensed
water it is also provided with a valve o for preventing inrush of air or water to the
casing. o is the condensed water overflow pipe.
The exhaust steam from an engine is supplied through the pipe to the top of the
casing and passes downwards through the tubes f to the outlet c at the lower end.
In its passage the steam heats. up the water surrounding the tubes. The 'cold
water is supplied continuously and automatically from the tank g. so long as hot
water is drawn off by the pipe c.
Live steam of course can be used if desired.
A perforated baffle plate r is preferably arranged so as to spread the steam on its
entrance into the casing.
A manhole door 8 is provided for gaining access to the exterior of the tubes and a
manhole door is provided for gaining access to the space below the bottom
partition for the purpose of facilitating the removal or insertion of the tubes.
To prevent the steam rushing too quickly through the tubes f retarders t of cup or
other shape are fitted in each tube." These retarders, as shown at fig. 3, may be
fitted on rods a jointed together and suspended within the tubes f. The retarders
also spray the hot condensed water against the sides of the tubes.
The water as it becomes heated flows upwards in the casing and tank to the
outlets i, k, in each case, and is drawn off as required.
According to the supply of hot water desired there may be either none or more
than one circulating tank.
The water may be supplied to the casing direct from a dam or pond, providing there
is a sufficient head of water instead of from the tank g.
The invention can be adapted for heating the feed water of steam boilers.
Having now particularly described and ascertained the nature of my said inven-

page_text: tion and in what manner the same is to be performed, I declare that what I
consider novel and desire to claim is :-
A water heater for paper mills, breweries and such like constructed and arranged
substantially as hereinbefore described with reference to the drawings annexed.
