An Improved Apparatus for Effecting the Cooling of Liquids.
I, THOMAS LEDWARD, of 35 Queen Victoria Street, City of London, Engin er.
do hereby declare the nature of this invention to be as follows:-
This invention relates to a novel construction of apparatus specially adapted for
rapidly cooling liquids.
The apparatus is to be made in positive sections interchangeable to facilitate
their easy connections or grouping to obtain large cooling surfaces in proportion
to the quantity of liquid to be cooled and the position in which the apparatus has
to be placed.
The invention mainly relates to what are known as outside or exposed
condensors and is composed of one or more corrugated metal plates set upright in
a frame of tubing formation on a hollow base and surmounted by one or more
tubes with nozzles or openings at its or their upper portion. I arrange baffle
plates or deflectors with plain or striated surfaces above the nozzles to receive and
break up the liquid into fine division and thin film like formation, and others
below but inverted to receive the broken up or disseminated particles to re-gather
them and lead them against one or against both sides of the corrugated plate or
plates, down which the liquid flows in thin sheet like form, following the
corrugations in its travel in order that every portion of the liquid may be
effectually cooled before collection in a trough or reservoir.
I provide taps or valves for regulating the passage of the liquid at convenient
parts of the tubing, and in order that the several parts of a section shall remain
intact I provide the end tubes with bolt holes, or 1 fit a web at each side and
employ stays or tie rods for the purpose.
Each section is complete as a self contained structure and can be transported,
and any number of thein can be connected by their flanged socket, or otherwise as
found convenient.

COMPLETE SPECIFICATION.
An Improved Apparatus for Effecting the Cooling of Liquids.
I, THOMAS LEDWARD, of 35 Queen Victoria Street, City of London, Engineer,
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 relates to a novel copstruction of apparatus specially adapted for ¨'
rapidly cooling liquids.
For the purpose of my said invention, I make any number of apparatus each
complete in itself and interchangeable to facilitate their easy connections ar
grouping to obtain large cooling surfaces in proportion to the quantity of liquid
to be cooled and the position in which the apparati has to be placed.

page_text: The invention cousists of an outside or exposed condeusor composed of one or
more corrugated metal plates set upright in a frame of tubing formation on a hollow
base and surmounted by one or more tubes with nozzles or openings at its or their
upper portion. I arrange baffle plates or deflectors with plain or striated surfaces
above the nozzles to receive and break up the liquid into fine division and thin film-
like formation, and others below but inverted to receive the broken up or
disseminated particles to re-gather them and lead them against one or against both
sides of the corrugated plate or plates down which the liquid flows in thin sheet
like form, following the corrugations in its travel in order that every portion of the
liquid may be effectually cooled before collection in a trough or reservoir.
provide taps or valves for regulating the passage of the liquid at convenient
parts of the tubing, and in order that the several parts of a section shall remain
intact provide the end tubes with bolt holes, or I fit a web at each side and
employ stays or tie rods for the purpose.
Each section is complete as a self contained structure and can be transported,
and any number of them can be connected by their flanged sockets or otherwise as
found convenient.
My invention is represented in the annexed drawings.
Figure 1 front elevation partly in section.
Figure 2 transverse sectional elevation through line a, b, of Figure 1.
A, trough base with water inlets B, B, at either end, each inlet being flanged
at C, C, for connection of supply pipe or pipes. D, D, column tubes affixed to
upper flanges E, E.
Each column tube D has a vertical flange or web F slightly out of the centre
for the attachment of one or more corrugated plates G the corrugations or
undulations being horizontally arranged and so shaped that the water to be cooled
shall lick to and keep itself in contact with the surfaces while flowing down, said
plates being secured outside and inside the webs alternately.
The upper edge of the plate G or of the top plate if more than one be fitted, is
slit at intervals, and the portions H, H, between the slits are bent outwardly
alternately for splaying the water into thin flat like films to the surfaces of the
plate or plates.
The upper and lower ends of the column tubes D, D, are flanged at I, I, for
connection to flauges E, E, of lower feed B, B, and also of top bends J, J, which
in their turn are secured to an upper horizontal tube K, the upper surface of which
is slitted lengthwise, or is provided with holes L for the passage of water which is
caused to strike upwardly against the underside of a cover M and then to rebound
or fall on to the exterior of the tube K to lick round it and be guided by the wavy
bottom wings N, N, with which it is provided on to the wings H, H, of the
plate D.
The cover is shaped and the bottom edges are wavy as at P, P, to break up
the water and lead it in flat streams, there being stops Q, Q, in the cover at intervals
to prevent the water of one stream mixing with the next one.
Each bend J, J, has a regulating valve R, R, one of which only is shown, the
descent of which into the columns D, D, by the screw stems S, S, determines the
quantity of water that shall pass into the tube K.
It will be observed that all the several pieces are made to a given pattern to
enable duplicates to be fitted should such be required from any cause, and that the
structure when built up is complete in itself, the flanges C, C, being in such positions
that the water supply pipe can be secured to one flange only and the other be
capped, or separate supplies can be given to each, or another similar structure can
be secured to the flange C at either or at both ends to make a series of coolers in
line, or by having other bends for coupling up a series back to back to constitute a
nest of coolers can be set in contiguity.
The cooled water entering the trough A can be drawn off by the outlet T which
may be central or otherwise.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The construction of apparatus for effecting the cooling of liquids in the
manner described, the several parts being arranged as shown on the annexed
drawings.
2. Casting the several parts of apparatus described, fitting the parts together as
represented on the drawings to constitute a complete structure, but capable of being
duplicated in any number of structures in contiguity and all fed from one supply,
as set forth.
