I, JOHN JAMES HENRY STURMEY, of 19, Hertford Street, Coventry, Warwick-
shire, Journalist, do hereby declare the nature of this invention to be as follows:-
My invention relates to cooling water devices for motors and consists in means
for keeping the cooling water cool by passing currents of air directly through the
said cooling water.
In carrying out my invention I arrange at or near the bottom of the cooling
water tank a tubular frame or a hollow grid having perforations in the upper
surface. The said frame or grid is connected with a tube which passes out of the
worked
tank above the water level and is also connected to a fan or air pump
directly or indirectly from the motor, or preferably by an auxiliary motor operated
by the exhaust of the main motor so that the power of the said main motor is not
encroached upon. The said fan or pump forces a continuous current of air through
the connecting pipe down into the frame or grid in the bottom of the tank.
Thence the air passes up from the perforations and traversing the water becomes
charged with the heat thereof, which heat is given off into the atmosphere when
the air escapes at the surface of the water. Thus the temperature of the water
is kept down by the continuous currents of air passing through the water. If
desired the air may be first compressed into a suitable reservoir by an occasionally
operated hand pump or by any other suitable means; the compressed air is
allowed to pass into the frame or grid, a regulating valve being preferably
employed to ensure a more constant current.
Where the motor as a whole passes through the atmosphere as in the case of the
motor of an autocar, the air pump, fan or reservoir may be dispensed with and
the air current caused to pass into the frame or grid through a wide mouthed
bell or trumpet having its mouth opposed to the direction of the passage of the
motor.
Improvements in or relating to Cooling Water Devices for motors.
I, JOHN JAMES HENRY STURMEY, of 19, Hertford Street, Coventry, Warwick-
shire, Journalist, 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:-
My invention relates to cooling water devices for motors and consists in means

page_text: for keeping the cooling water cool by passing currents of air directly through the
said cooling water.
And in order that my invention may be properly understood and readily carried
into effect I will describe the same with the aid of the accompanying drawings
wherein,
Figure I is a side elevation partly in section of one form of my cooling device.
Figure II is a plan showing means for operating the cooling device by the
exhaust from the motor.
Figures III and IV are side elevations of modified forms of my cooling device.
Like numerals refer to like parts in all the figures.
In carrying out my invention according to the method shown in Fig. I, I
arrange at or near the bottom of the cooling water tank 2, either a tubular frame
or, as shown, a grid 3 fitting closely in the tank at a suitable distance from the
bottom thereof so as to form a chamber 20 having perforations 19 in the upper
surface. Connected to the said grid 3, by any suitable means, is a tube 4, the
lower end of which passes through the said grid and opens into the chamber 20;
the said tube passes out of the tank above the water level 5 and is also con-
nected to a suitable airpump or a fan 6 worked directly or indirectly from the
motor, or by an auxiliary motor operated by the exhaust of the main motor so
that the power of the said main motor is not encroached upon.
This latter device may be arranged as shown in Fig. II where the exhaust issues
from the pipe 7 into a receiver 8 whence it passes along the pipe 9 to the vanes
of a wheel 10 which it causes to rotate in its casing 11. The axle 12 of the
wheel 10 extends into the casing 13 of the fan 6 and carries the vanes of the
said fan. The injector device 7, 8 is employed to prevent back pressure, and so
much of the exhaust as passes into the casing 11 escapes therefrom through the
aperture 14 which is directed away from the casing of the fan 6 so that the
air drawn into the said fan may not be heated by the said exhaust. The fan 6
forces a continuous current of air through the connecting pipe 4 down into the
chamber 20 in the bottom of the tank. Thence the air passes up through the
perforations 19 and traversing the water becomes charged with the heat thereof,
which heat is given off into the atmosphere when the air escapes at the surface of
the water. Thus the temperature of the water is kept down by the continuous
currents of cold air passing through the water. When the fan is driven by the
motor I provide means for throwing the fan out of action, so that the full power of
the motor may be available if special circumstances demand it.
If desired the air may be first compressed into a suitable reservoir 15 by an
occasionally operated hand pump 16 as shown in Figure III, either with or
without the fan or by any other suitable means; the compressed air is allowed
to pass through the tube 4 into the chamber 20, a regulating valve 17 being
preferably employed to ensure a more constant current."
Where the motor as a whole passes through the atmosphere, as in the case of
the motor of an autocar, the air pump, fan or reservoir may be dispensed with
and the air current caused to pass into the frame or chamber through a wide mouthed
bell or trumpet 18 formed on the end of the tube 4 and having its mouth opposed
to the direction of the passage of the motor, as shown in Figure IV.
I do not confine myself strictly to the details of the above description and
accompanying drawings, but hold myself at liberty to make such modifications as
fall fairly within the scope of my invention.
Having now particularly described and ascertained the nature of my said inven- 5
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. The herein described means for keening cool the cooling motor of matron

page_text: tubular frame or a grid arranged at or near the bottom of the tank so as to form
a chamber having perforations in its upper surface, an air pump or fan with
suitable means for operating the same, and a tube connected at one end to such
frame or grid, passing out of the tank above the water level and communicating
at the other end with the said air-pump or fan, all combined, arranged and adapted
to operate substantially as set forth.
3. In a motor, the employment of the power of the exhaust for operating a
cooling water device of the kind referred to in Claim 1 hereof.

tubular frame
4. Means for keeping cool the cooling water of motors, consisting in
Ol' a grid arranged at or near the bottom of the
tank so as to form a chamber having perforations in the upper surface, suitable
means for compressing air, a reservoir to contain such compressed air, and a tube
connected at one end to such frame or grid passing out of the tank above the
water level and communicating at the other end with the said reservoir, with or
without a regulating valve, all combined, arranged and adapted to operate, sub-
stantially as set forth.
5. Means for keeping cool the cooling water of motors adapted to pass through
the atmosphere consisting in a tubular frame or a grid arranged at or near the
bottom of the tank so as to form a chamber having perforations in the upper
surface, a tube connected at one end to such frame or grid, passing out of the tank
above the water level and having at the other end a bell mouth opposed to the
direction of the passage of the motor, all combined, arranged and adapted to
operate substantially as set forth.
6. A cooling water device for motors, constructed substantially as herein
described with reference to one or other of the forms shown in the accompanying
drawings.
