An Improved Process of Cooling Condenser-water for Steam Engines.
I GILBERT RICHARD REDGRAVE of The Elms, Westgate Road, Beckenham,
in the County of Kent, Associate of the Institution of Civil Engineers do hereby
declare the nature of this invention to be as follows:-
The object of this invention is the cooling of water used for the condensation
of steam. In carrying out my invention I employ a series of so-called "spray.
producers," which by means of jets of compressed air, brought into contact at any
suitable angle with streams of water, issueing from the orifices of tubes, disperse
the water in extremely fine particles. I cause these particles of water to be driven
against vertical screens of wood or other suitable substance, down which the water
trickles and collects in a trough or reservoir at the base. The combined action
of the air-jets and the evaporation from the large area of cooling surface rapidly
lowers the temperature of the water. In hot weather I may cause a stream of
cold water to pass down the vertical cooling surface. If necessary the same water
may be employed several times over for the production of spray, by connecting
the reservoirs at the base with the pumps.
Dated this 20th day of October 1896.

An Improved Process of Cooling Condenser-water for Steam Engines.
I GILBERT RICHARD REDGRAVE of The Elms, Westgate Road, Beckenham,
Kent, Civil Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to he particularly described and ascertained
in and by the following statement:
The object of this invention is the cooling of water used for the condensation of
steam. In carrying out my invention I employ a series of so-called
spray-producers," which by means of jets of compressed air, coming into contact
at suitable angles with streams of water, issueing under pressure from the orifices
of small pipes, break up the water into extremely fine particles. These spray-
producers are arranged in tiers on either side of a set of vertical screens, which
may be of any desired height. I cause the particles of water to disperse in a
direction inclined upwards, and to be deposited on the aforesaid screens, where they
encounter a thin stream of cold water constantly flowing downwards. This water
collects in troughs, or in a reservoir, at the base of the screens. The combined
action of the air-jet and consequent formation of spray, the vertical cooling

water, and I so arrange the reservoir that if necessary the heated water can be
employed several times over for the production of the spray, and thus become more
effectually cooled, or it may at once be conducted back to the condenser of the
engine for re-use.
Having now particularly described and ascertained the nature of my said
irvention, and in what manner the same is to be performed, I declare that what
I claim is:-
The combined use of spray-producers and vertical screens, chilled by a stream
of falling water, so that the heated water from the condenser of the steam engine
is converted by the spray-producer into extremely fine particles, in a jet of cold
air, and these particles are driven against a large surface of chilled water in the
manner described and are thus rapidly deprived of their heat for reuse in the
condenser.
