Improvements in or relating to Water Cooling Devices for Motors,
Air Compressors, Steam Engines, and the like.
We, RAOUL GANDRILLE, EMILE ROUSELLE, and AMÉDÉE DAGUE, Engineers, of
Fives-Lille, France, do hereby declare the nature of this invention to be as
follows:
This invention relates to means of cooling the circulating water used for cool-
ing the walls of the cylinders of motors, air compressors and the like, and which
may also be employed in cooling the condensed water of steam engines.
The device is characterized by the arrangement of two concentric walls or
chambers made wholly or partly of trellis work, metallic tissue, perforated plates
or the like surmounted by a cover or circular dome having a top like a trun-
cated cone or of other suitable shape. The water is introduced in the top part of
the apparatus in a free spray and is preferably brought in contact with a cur-
rent of air drawn up as it issues from the centre of the upper orifice of the top
conical wall of the inner chamber. The walls of the two concentric chambers
are connected with each other by metal rings inclined alternately in one and
the other direction, such rings forming obstructions, retarding the flow of the
water, which is already retarded by its passing down the open-work walls, owing
to capillary action, the object being to expose the water as much and as long
as possible to the action of the air which passes through these walls on all sides
so as to ensure a thorough cooling of the water.

In the interior of the apparatus is arranged a sprayer" which forces the
water in the state of a fine spray into the upper portion of the outer chamber so
as to expose every particle of the water to the action of the cold air drawn up by
the jet of water issuing from the sprayer." The upper part of this device is
provided with a tube closed at its upper end so as to neutralise the beats of the
pump and to regulate the issue of the water, this tube being separated from
the water admission tube by the sprayer, although placed in the prolongation of
the admission tube.
The refrigerator can be applied to motor vehicles. For this purpose it is pre-
ferably made of a series of trellis or open-work plates placed vertically in front
of the vehicle at different heights which are acted upon by the current of air
produced by the movement of the vehicle. The water running along one plate
passes into a cup or plate from which it falls on the second plate to be again
received by a second cup and so on until the water arrives at the bottom cup or
receiver from which it may be forced by a pump into the cylinder jacket.
An arrangement similar to the foregoing, with perforated or open-work plates,
either straight or curved, and cups may also be used for stationary motors.

page_text: Improvements in or relating to Water Cooling Devices for Motors,
Air Compressors, Steam Engines, and the like.
We, RAOUL GANDRILLE, EMILE ROUSSELLE, and AMEDEE DAGUE, Engineers, of
Fives-Lille, France, 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 means for cooling the circulating water used for cool-
ing the walls of motor cylinders, air compressors and the like.
The apparatus offers the advantages of spraying device combined with means for
causing the water to travel in the form of a very thin sheet, the passage of the
water being very slow so as to allow the ambient air to pass through the sheet
of water as they flow along as well as through the water issuing from the spray-
ing device.
In the accompanying drawing:-
Figure 1 represents a schematic view of a suitable arrangement of apparatus.
Figure 2 is a vertical section, and
Figure 3 is a plan view of the apparatus, while
Figures 4 and 5, are a vertical section and plan view respectively, of the
sprayer, on an enlarged scale, and
Figure 6 is also a sectional view, on an enlarged scale of the means employed
for retarding the flow of the water to be cooled.
a and bare two parallel cylindrical walls constructed of trellis, perforated or
woven metal work. Annular rings c of sheet metal connect the two cylindrical
walls, the rings being so arranged that they are alternately inclined in opposite
directions, as shown in Figure 2.
The inner wall is surmounted by a truncated cone of sheet metal.
The outer wall a is surmounted by a cylindrical unperforated wall extension,
or cover e, which, in its turn, is surmounted by a non-perforated truncated cone f
on which is arranged a cylindrical top g.
h is a tube through which the water to be cooled is admitted the water being
supplied from a pipe i.
The tube is provided with a spraying device, made essentially of two parts j
and (Figure 4) between which the water will issue in the form of a circular
spray the thickness of which can be rendered as small as desired, so as to produce
an effective spray.
The spraying device is surmounted by a tube closed at its upper end.
m represents the motor, or the compressor round which the cooling water
circulates; n is a vessel into which the water is drawn by the suction of a pump o
which then drives the water through the pipe i upwards through the tube h
after having cooled the motor.
This water in passing between the two parts of the sprayer and is divided
into minute particles which are thrown outwards into the chamber A formed by
the walls f, e and d. This water jet produced, by its speed a current of air which is
drawn up through the walls a and b, passes through the upper orifice of the
truncated cone d, thence through the particles of sprayed water in suspension
within the chamber A, and finally passes out by the outlet g.
Thus the first phase in the course of cooling the water is effected by the air
which passes across the chamber A. The water then runs down the inner side
of the walls e and the outer surface of d, after which it passes on along the open-

page_text: work walls a and b where its rapid descent is checked by capillary action while
the air can pass freely from the outside to the inside of the apparatus.
Finally, the check rings c c arranged alternately in opposite directions between
the walls, are also calculated to retard the downward flow by opposing any
acceleration of speed and causing the water to continually pass alternately from
the wall a to wall b and back again.
Arriving at last at the bottom of the walls a and b, the cooled water falls
into the reservoir n arranged below it.
The air imprisoned in the extension tube / forms a kind of cushion, neutralizing
the beats or impulses produced by the pump, in the tube and regulating
the overflow of the water.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
what we claim is:-
1. A water cooling apparatus for motors, air compressors, steam engines and
the like, comprising two concentric walls of metallic trellis open work sur-
mounted by more or less closed parts preferably of truncated cone shape, said
upper parts forming a chamber in which the water sprayed from a central pipe
is traversed by the induced current of air drawn up by the spraying device at
the upper part of the lower truncated cone wall surmounting the inner openwork
wall; the two openwork walls having between them metal sheet rings forming
oblique water checks, inclined alternately in opposite directions, for the purpose
of further retarding the downward movement of the water, already retarded
during its passage over the openwork walls owing to capillary action, in conse-
quence of which the water is exposed during a considerable time to the cooling
effects of the air passing through the walls substantially as described.
2. In a water cooling apparatus of the kind described a water ejector tube
provided with a spraying device and a closed extension of said tube beyond the
spraying device for the purpose of forming an air reservoir or buffer for neutraliz-
ing the sudden impulses which are produced in the spraying device in conse-
quence of the strokes of the pump piston thereby regulating the issue of the
sprayed water, substantially as described.
3. A water cooling apparatus of the kind described comprising two concentric
openwork cylinders, a closed conical cover on the top of the inner cylinder a
circular closed extension with conical top on the top of the outer cylinder, a
series of rings inclined alternately in opposite directions between said concentric
cylinders and a central water supply pipe provided with a spraying device above
the conical top of the inner cylinder substantially as described.
4. The complete water cooling apparatus substantially as described or illus-
trated in the accompanying drawings.
