HENRY SAMUEL BOASE and CHARLES Miller, both of Dundee, in the County of
Forfar, North Britain. AN IMPROVED METHOD OF COOLING WATER DISCHARGED
FROM CONDENSING ENGINES AND FOR COOLING OTHER LIQUIDS."
This Invention which relates to the cooling of water discharged from condensing
engines and to the cooling of other liquids, consists in effecting the same by the
application to the said heated liquids of centrifugal force produced by the action of
steam, water, or other motive power upon the centrifugal apparatus.
In carrying the Invention into practice the water or other liquid to be cooled is
discharged into a bollow vessel with perforated sides, through which the said liquid
is thrown out by centrifugal force in drops more or less minute, and cooled by
exposure in this state to the atmosphere or to a current or currents of air which
may be artificially cooled if desired.

HENRY SAMUEL BOASE and CHARLES MILLER, both of Dundee, in the County of
Forfar, North Britain. "AN IMPROVED METHOD OF COOLING WATER DISCHARGED
FROM CONDENSING ENGINES AND FOR COOLING OTHER LIQUIDS."
Our said Invention relates to the cooling of water discharged from condensing
engines and to the cooling of other heated liquids, and consists in effecting the
same by the application to the said hented liquids of centrifugal force, so as to
cause the said liquid to be exposed in drops to the cooling effect of the atmosphere
or of artificially cooled air.
And in order that our said Invention may be properly understood, we now
proceed more particularly to set forth the system, mode, or manner in or under
which the same is or may be used or practically carried into effect, reference
being had to the accompanying Drawings, and to the letters and figures marked
thereon, that is to say :-
Figure 1 represents in elevation, and Figure 2 in plan, an apparatus for carrying
our Invention into operation; Figure 3 is a transverse section of the perforated
vessel and basket separately, as hereinafter described. The said apparatus is erected
in the pond or other place whereinto the discharged water is to fall. The water
or other liquid to be cooled is conveyed by the pipe or conduit A into a vessel B,
the lower portion of the sides of which are perforated, through which perforations
the liquid is discharged in small jets against the sides of a revolving basket C, of
wire cloth or gauze, which surrounds the perforated part of the vessel B. The
water is then thrown from the sides of the basket C in drops, which are cooled by
exposure to the atmosphere. The vessel B is hung from the beam D by brackets d,
and the basket C is mounted upon a spindle c, turning in bearings at d, d³, and
rotated by any suitable motor through the pulley C. An inner casing b, forming
part of the vessel B, encircles this spindle and protects it from the liquid. The
vessel B and basket C may be constructed in any convenient manner. As shewn,
the basket C is made of a circular plate c, to which are attached vertical ribs c³,
bound together at top by a ring c. To the said ribs c³ wire cloth c³ is attached,
cither one thickness of fine wire cloth or two thicknesses of coarser cloth, one outside
and the other inside the ribs. The vessel B, as shewn, may be constructed on the
same principle, consisting of three rings 62, 63, 64, the rings b² and 63 being connected
by ribs b and the rings 63 and 6 by ribs 66, to which ribs the covering of the vessel
is affixed. A piece of wire gauze may be inserted at a in the inlet pipe or conduit
A to strain the entering liquid.
Figure 4 represents in elevation, partly in section, a slightly modified form of
apparatus in which the inlet A for the liquid to be cooled is beneath. The vessel B
in this case is closed at top. The parts which correspond with those of the
apparatus shewn in Figures 1, 2, and 3, are marked with the same letters of
reference and require no further description.
Figure 5 represents in elevation, partly in section, and Figure 6 in plan, partly
in section, an apparatus for cooling liquids according to our Invention in confined
spaces by artificially cooled currents of air or currents of air at ordinary
temperatures.
The vessel B and the basket C are similar to those hereinbefore described, but
are enclosed in a casing or chamber E, surrounded by an air pipe F, into which air
is forced (by a fan or otherwise) at femerging by nozzles f,, into the chamber E.
The said pipe F is surrounded by a water pipe G, to which cold water is admitted
at and from which it flows at g². This water cools the air admitted by the
pipe F. The basket C is driven from below by a friction plate and wheel h, h³.

page_text: The steam escapes from the chamber E by openings at e, e. The liquid to be cooled
is passed into the vessel B, as explained with regard to Figures 1 and 2, and is
cooled as it is presented in drops to the cool air in the chamber E, from which as
it collects it is drawn by a tap or cock at e².
The number of the holes in the vessel B, and their size, and the fineness of the
gauze of the basket C, will depend on the rate at which the liquid is discharged into
the said vessel, it being desirable to maintain the liquid as nearly to the top of the
said vessel as is practicable. We have found, for example, that for cooling the
water discharged from combined engines of 95 nominal horse power, that a vessel B,
having 10,000-inch holes in it, and a basket covered with one thickness
of inch mesh wire cloth, and driven at a rate of about 3,000 feet per minute,
answer well in practice.
The liquid to be cooled may be introduced into a revolving basket having
perforated sides, and discharged in drops and cooled without the employment of au
intermediate vessel.
Having now described and particularly ascertained the nature of our said
Invention, and the system, mode, or manner, in or under which the same is or may
be used or practically carried into effect, we would observe in conclusion that we
do not limit ourselves to the precise details hereinbefore described and illustrated
in the accompanying Drawings, as the same may be varied within considerable
limits without departing from the nature of our Invention; but what we consider
to be novel and original, and thorefore claim as the Invention secured to us by the
hereinbefore in part recited Letters Patent, is,
The hereinbefore described improvements in cooling water discharged from con-
densing engines and other liquids, that is to say, effecting the said cooling by the
application of centrifugal force, the said force being so applied as to cause the liquid
to be cooled to be presented to the atmosphere, or to artificially cooled currents of
air in drops or in a finely divided state, essentially as hereinbefore described with
reference to the accompanying Drawings.
In witness whereof, we, the said Henry Samuel Boase and Charles Miller,
have hereunto set our hands and seals, this Twenty four day of March,
in the year of our Lord One thousand eight hundred and eighty.
