Improvements in Apparatus for Cooling Liquids.
I, WILLIAM GEORGE HEYS of 70 Market Street Manchester in the County of
Lancaster, Chartered Patent Agent, 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
"
This invention has reference to apparatus or appliances which are employed in the
cooling of water and other liquids and particularly in the cooling of water from the
condensers of steam engines, and it has been especially devised with the object of,
obtaining a higher efficiency and of avoiding the necessity for pumping the liquid,
to be cooled.
According to the present improvements my foreign correspondent has arranged for.
the construction, preferably in timber, of a very large cooling area in a comparatively.
small space and that the liquid to be cooled shall, during its- passage through the
apparatus, be repeatedly broken up and deviated. He has also arranged the apparatus.
at such a height that, when convenient and desirable, the water from the hot well of
a condensing engine for example, can flow by gravity to and over the cooling, area
without being elevated by pumping or otherwise.
"I will further describe the said Invention with, reference to the accompanying
drawings.
.!
Figures 1 and 2 represent vertical sections taken at right angles to one another
through one form of the apparatus.
In this form, the cooling area is made up by the surfaces of a considerable number
of rectangular rods R, shewn on a larger scale by Figure 3, in cross section. The
ends of these rods are carried by lattices L, in such a manner that all the rods have.
their angles in vertical and horizontal planes and that the rods in either plane break,
pitch with those in the similar contiguous plane. The liquid to be cooled arrives at
the apparatus by the pipe A, whence it runs into the trough B, from which it is
preferably distributed through the branches C C, to the troughs D D, which are
arranged at right angles with the trough B. The upper edges of the distributing
troughs D may be notched as shewn at E, and the liquid flows through these notches
upon the upper angles of the higher beds of rods R. As the liquid flows down the
inclined sides of the rods, part of it is deflected from each rod upon the rods to the
right and to the left in the next lower bed and part drips from the lower angles
upon the rods vertically under them, as indicated by Figure 3. The rods R which
are nearer to the bottom of the apparatus may have a greater length than the
higher ones, as shewn by Figure 2, so that any liquid flowing to the ends of the rods
in the higher beds may not fall direct into the reservoir F, without being broken up
and deviated. If the apparatus be enclosed and be surrounded by or connected with a

page_text: chimney, an upward current of air, as indicated by the arrows Figure 3, will be
induced which will facilitate the cooling effect. Deflector plates G may be employed
above the highest bed of rods for the purpose of leading the liquid upon the
individual rods as it falls from the distributing troughs.
In the apparatus constructed as represented by Figures 4 and 5 in a similar
manner, beds of rods resembling those shewn by-Figures 1 and 2 are employed in
multiple, that is to say, two or more sets (in this case three sets) of the apparatus
are arranged one above the other, but so that each set is arranged at right angles
with its immediate neighbours above and below. As shewn by the figures, each set
is vertically divided and this arrangement involves a slight modification in the
arrangement of the liquid distribution. Instead of a single trough B, there are two
such troughs which are supplied from the pipe A through the intermediate trough H
and branches I I. The flow of the liquid through the apparatus is substantially the
same as in the apparatus described with reference to Figures 1 and 2, with the
addition that the flow is further broken up by the different directions in position of
the beds of rods. The apparatus is represented as being surmounted by a wooden
chimney; as being enclosed by the walls K; and as being provided with the louvred
deflectors L₁, but these are accessories which may or may not be employed.
In the modification represented by the two vertical sectional views Figures 6 and 7,
which are also supposed to be taken at right angles with each other, the cooling area
is composed of a plurality of parallel inclined lattices M M. At that end of the
system upon which the water or liquid first falls from the troughs B D, the ends of
the lattices are arranged in a diagonal plane so that the water may be delivered
upon them all, as shewn. The water or liquid is received upon the upper ends of the
longitudinal laths which are uppermost in the lattices, and part of it trickles down
their whole length and falls from the lower ends of the laths into the reservoir F.
Another part of the liquid falls off the longitudinal laths upon the transverse lower
laths from which it falls, partly stepwise upon the next lower and successive
transverse laths through the whole series, and partly upon the next lower longitudinal
laths. Finally, by its various paths, the liquid reaches the reservoir F. In this case
also the appliance is represented as being partly enclosed and connected with a
chimney J for the purpose of inducing an upward air current, but these accessories
may be dispensed with.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :-
1. Apparatus for cooling water and other liquids, constructed and arranged
substantially as hereinbefore described and as illustrated by Figures 1 and 2 of the
accompanying drawings..
2. Apparatus for cooling water and other liquids, constructed and arranged
substantially as hereinbefore described and as illustrated by Figures 4 and 5 of the
accompanying drawings.
3. Apparatus for cooling water and other liquids, constructed and arranged
substantially as hereinbefore described and as illustrated by Figures 6 and 7 of the
accompanying drawings.
