I, SAMUEL SMILLIE of 71 Lancefield Street, Glasgow, in the County of Lanark,
Copper-smith, do hereby declare the nature of my said Invention for "IMPROVE
MENTS IN APPARATUS FOR HEATING AND COOLING FLUIDS," to be as follows:―
This Invention has for its object to provide simple and improved apparatus for
heating and cooling fluids, as for example, for condensing steam in order to obtain
fresh water, and for heating feed water for steam boilers.
The improved apparatus consists of a series of tubes arranged' within a casing,
and expanded or otherwise fitted at their ends into the inner plates of boxes which
form the top and bottom of the casing. Within each of these tubes is fitted a
smaller tube whose ends terminate in the outer plates of the boxes, but some
distance within the top and bottom ends or end covers of the apparatus. The
boxes at top and bottom are provided the one with an inlet, and the other with ap
outlet, and in the case where the apparatus is used as a fresh water condenser,
steam is admitted by the inlet and passes through the annular spaces between the
internal and external tubes wherein it is cooled and condensed by the action of
cold water or other cooling agent circulated round the external tubes, and through
the internal tubes, and it passes by the outlet in the form of distilled water.
When applied as a feed water heating apparatus, the water passes through the
annular space between the tubes, and the exhaust steam through, the smaller tubes
and through the casing outside the tubes.

I, SAMUEL SMILLIE of 71, Lancefield Street, Glasgow, in the County of Lanark,
Coppersmith, do hereby declare the nature of my invention for IMPROVEMENTS
IN APPARATUS FOR HEATING AND COOLING FLUIDS" and in what manner the same
is to be performed to be particularly described and ascertained in and by the
following statement :-
This invention has for its object to provide simple and improved apparatus for
heating and cooling fluids as for example, for condensing steam in order to obtain
fresh water, and for heating feed water for steam boilers.
The invention is illustrated by the accompanying drawings in which figure 1 is
a vertical section and figure 2, a sectional plan of, my improved apparatus.
The improved apparatus consists of a series of tubes a arranged within a
casing A and expanded or otherwise fitted at their ends into the inner plates of
boxes B B¹ which form the top and bottom of the casing..."
Within each of these tubes a is fitted a smaller tube 6 whose ends terminate in
the outer plates B₁ of the boxes, but; some distance within the top and bottom
ends or end covers of the casing A of the apparatus. The boxes B Bat top and
bottom are provided the one with an inlet C, and the other with an outlet D; and
in the case where the apparatus is intended for use as a fresh water condenser, as
in the example illustrated steam is admitted by the inlet C.and passes through the
annular space c between the internal and external tubes a. b..wherein it is cooled
and condensed by the action of cold water or other cooling agent admitted by an
opening E in the casing to circulate round the external tubes, and through the
internal tubes a, on its way to an outlet F; and the steam passes by the outlet D
in the form of distilled water.
J
When applied as a feed water heating apparatus, the water passes through the
annular space c between the tubes, and the exhaust steam through the smaller.
tubes band through the casing A outside the tubes a..
:
A métallic diaphragm G may form the lower end of the casing A and permit
of the movement of the, parts due to expansion or contraction...
Figure 3 is an elevation showing the tubes a secured in the boxes B B¹ and also
showing the inlet C. Figure 4 is an elevation showing the mode of securing. the
inner tubes b in the outer plates of the boxes by means of screw nuts. A helical
thread is or may be formed on or round the tubes.b to partially 'intercept the
steam or water passing through the annular space o between the tubes, and permit
of greater exposure to the action of the steam or water circulating through the
inner tubes 6 and through the casing A.
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
223
The combination of parts forming the improved apparatus for heating and
cooling fluids substantially as herein described and illustrated.
