Improvements in Water Cooling Tanks for use in connection with
Internal Combustion Engines.
We, HUBERT BERGER GRAHAM, of 116, St. Stephen's Avenue, Notting Hill, in
the County of London, and THOMAS WILLIAM BLUMFIELD, of Ernest Street Works,
Birmingham, in the County of Warwick, Engineers, do hereby declare the nature
of this invention to be as follows:-
This invention has for its object to provide improved means for cooling the
water used for cooling the cylinders of internal combustion engines and it consists
in providing a cooling tank having pipes arranged in the novel manner hereinafter
described through which air is caused to circulate.
According to this invention the water tank has a series of vertical tubes passed
through it open at the top and bottom so that air can circulate freely through
them, and through the sides of the tank horizontal tubes extend into the vertical
tubes so that air can enter the vertical tubes through the horizontal tubes.
In practice an air pump is advantageously arranged in connection with the
horizontal tubes and baffles or valves are arranged in the vertical tubes in such a
manner that the air as it enters the pump is drawn through the lower. ends of the
vertical tubes and as it is discharged from the pump escapes through the upper
ends.
If desired a fan or other device may be used for promoting the air circulation,
and in some cases, as for instance when our invention is fixed upon a motor car,
the motion of the vehicle may cause the air circulation.

Improvements in Water Cooling Tanks for use in connection with
Internal Combustion Engines..
We, HUBERT BERGER GRAHAM, of 116, St. Stephen's Avenue, Notting Hill, in
the County of London, and THOMAS WILLIAM BLUMFIELD, of Ernest Street Works,
Birmingham, in the County of Warwick, Engineers, 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 has for its object to provide improved means for cooling the
water used for cooling cylinders of internal combustion engines and it consists

page_text: in providing a cooling tank having pipes arranged in the novel manner hereinafter
described through which air is caused to circulate.
According to this invention the water tank has a series of more or less vertical
tubes passed through it open at the top and bottom so that air can circulate freely
through them and through the sides of the tank, cross tubes extend into the vertical
tubes so that air can also enter the vertical tubes through the cross tubes.
To enable our invention to be fully understood we will describe the same by
reference to the accompanying drawing, in which; -
Figure 1 is a front elevation; and,
=
Figure 2 a side elevation of a cooling tank constructed according to our invention.
a indicates the tank proper, which, as shewn, is provided with nozzles b, c for
the attachment of the water circulating pipes.
d, dare the tubes which extend through the tank from top to bottom, and e, e
are the cross tubes which extend from the face of the tank into the tubes d, d.
When our water cooling tank is to be used upon a motor car or other moving
support, the tubes e, e are arranged to extend to the front face of the tank so that
as the tank meets the air a current of air will be caused to flow through them into
the tubes which air as it passes through the upper parts of the said tubes a will
induce a current of air through the lower portions of the said tubes.
In order to further increase the current of air the tubes e, e are advantageously
provided with a funnel mouth such as f and the lower ends of the tubes d with
cowls g which are in the direction of movement whilst the upper ends of the said
tubes d are provided with cowls h which open in the opposite direction to the
movement so that they will tend to cause a suction.
In some cases if the speed at which the tank is moved is not sufficient to produce
the requisite air currents, a pump or fan may be used for increasing the draught.
When a pump is used we advantageously arrange a baffle which extends across
the tube and along the tube e as indicated by the line in Figure 2 and we
connect the suction side of the said pump to the passage way beneath this baffle
and the delivery side of the pump to the passage way above the said baffle.
Although in the drawing we have represented the tank as being provided with
three sets of pipes d and e it is to be understood that a greater or less number may
be used according to requirements.
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. In a water cooling tank for use in connection with internal combustion
engines, the arrangement therein of a pipe or pipes extending through the same from
top to bottom and having connected with it or them a cross pipe or cross pipes,
substantially as described.
2. The manufacture and use of water cooling tanks with air circulating pipes
therein, substantially as herein before described and illustrated in the accompanying
drawing.
