PROVISIONAL SPECIFICATION.
Improvements in Cooling the Cylinders of Explosion Engines.
I, FREDERICK RICHARD SIMMS, of Amberley House, 12, Norfolk Street, Strand,
in the County of London, Engineer, do hereby declare the nature of this inven-
tion to be as follows:-
This invention relates to improvements in cooling the cylinders of internal
combustion or explosion engines, the improvements being more particularly
applicable for use in connection with the driving engines of motor cars and
especially in those cases where the motors are of high power and require a
large quantity of cooling water.
According to the invention I employ in connection with the usual water
jacket of the explosion engine or motor a kind of pipe or drum made of coils
of a copper or other suitable tube, the said drum being provided with external
flanges or gills for increasing the external area of the said drum. In conjunc-
tion with the coiled tube 1 arrange a suitable device for causing water to
circulate through the system, such, for instance, as a pump or a collapsable
bladder or the like.
At one side of the drum or coiled tube I furnish a fan arranged to drive or
draw air over the drum, the said fan being advantageously mounted upon the
motor shaft or arranged to be driven from the said shaft. The current of air
set up by the fan impinges against the external flanges or gills in such a
manner that the heat given to the circulating water by the cylinder is carried
away by convection.
In practice I find it advantageous to construct the water circulating drum in
the following manner, that is to say, I take the tube of copper or other suitable
material and coil a portion of it around a drum so as to form a pipe having
an internal diameter corresponding to the external diameter of the drum. The
uncoiled end of the tube is then turned back inside the coiled portion and
wound upon a smaller drum in the opposite direction, this operation being
repeated as often as the diameter of the external coil will permit. The flanges
or gills are then passed on to the pipe or drum so formed and the pipe is extended
by hydraulic pressure to fix the said flanges or gills in position.

and ascertained in and by the following statement: —
This invention relates to improvements in cooling the cylinders of internal
combustion or explosion engines, the improvements being more particularly
applicable for use in connection with the driving engines of motor cars and
especially in those cases where the motors are of high power and require a
large quantity of cooling water.
According to the invention I employ in connection with the usual water
jacket of the explosion engine or motor a kind of pipe or drum made of coils
of a copper or other suitable tube, the said drum being provided with external
flanges or gills for incréasing the external area of the said drum. In conjunc-
tion with the coiled tube I arrange a suitable device for causing water to
circulate through the system, such, for instance, as a pump or a collapsable
bladder or the like.
At one side of the drum or coiled tube I furnish a fan arranged to drive or
draw air over the drum, the said fan being advantageously mounted upon the
motor shaft or arranged to be driven from the said shaft. The current of air
set up by the fan impinges against the external flanges or gills in such a
manner that the heat given to the circulating water by the cylinder is carried
away by convection.
In the accompanying drawings,--
Figure 1 is a front view of tubular cooling apparatus constructed according
to my invention.
Figure 2 is a sectional side elevation thereof:
Figures 3 and 4 are a cross section and a sectional elevation of a portion of
one of the tubes shewn with ribs or gills, these views being drawn to a larger scale.
Figure 5 is a sectional elevation of a modified construction of apparatus; and
Figure 6 is a plan thereof;
Figures 7 and 8 are views similar to Figures and 6 respectively of a further
modification.
A is the cylinder of the motor. a is the pipe or tube forming the drum through
which the water from the water jacket of the motor is caused to flow for cooling
purposes, the said pipe being advantageously made of copper which is a good
heat conducting substance.
In the arrangement shewn in Figures 1 and 2 the cooling drum is formed
from the tube a in the following manner, that is to say, the tube a is coiled
around the drums to form a number of pipes having an internal diameter corre-
sponding to the external diameters of the drums. The coiled pipes are then
inserted into one another, the alternate pipes having been coiled preferably to
form right and left hand spirals as shewn. Or the whole can be made from a
single length of tube which is first coiled in one direction, turned back on itself
and coiled in the other direction inside the first coil and so on as often as the
diameter of the external coil will permit.
The coils can be wound closely together so that the whole forms a practically
solid pipe upon which ribs or gills, for assisting the cooling action can be
suitably fixed. Or the tubes a can be more or less loosely coiled as shewn in
Figures 1 and 2 and the gills or ribs inserted upon the coiled tubes themselves;
such gills can advantageously be made of aluminium corrugated or waved as
shewn at b, b Figures 3 and 4 to increase their surface.
The ends of the tubes a at either end of the drum are secured to tanks c and d
respectively in communication with the water jacket of the motor, the tank c
being provided with a filling plug c and the tank d with an emptying cock d'.
e is the fan which is rotated in any suitable manner from the motor so as to
drive a current of air over the coiled tube a, the said air impinging against the
gills or ribs b, b so that the heat given to the water circulating through the
drum is carried away by convection.

page_text: Any suitable means may be employed for causing the water to circulate through
the system; for instance a pump or a collapsable bladder or the like.
In the construction illustrated in Figures 5 and 6 the continuous tube a is
bent backwards and forwards into the formation shewn the continuous tube
can, of course, be made in sections connected by union joints. f, f are clamping
plates and y, y distance pieces which are waved or undulated to receive the lengths
of tube and are held in position by the bolts h, h. In this arrangement the
ends of the tube a are connected to the motor water jacket.
The arrangement shewn in Figures 7 and 8 is similar to chat just described
but the cluster of tubing a is held together by the rings i, i which are applied
externally upon the tubulous cluster, being secured together at a suitable distance
apart by the bolts j, j and the distance pieces k, k. The rings are provided with
a kind of wire network through the holes in which the tube lengths pass as
clearly shewn in Figure 7. m, m are copper plates which I can insert between
the rows of tubing to increase the cooling surface: the said plates are held in
place by their slightly undulated form and by their ends which are bent partly
round the end tubes of each row.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:--
1. The combination with the water jacket of an explosion engine of a coiled
tube or tubes through which the water from the jacket circulates and over
which a current of air is projected, substantially as hereinbefore described.
2. The combination with the water jacket of an explosion engine of a tube
or tubes coiled in opposite directions to form a kind of drum, the ends of the
tube or tubes being connected to two tanks or the like in communication with
the water-jacket, of means for circulating the water through the system and of
a fan for blowing air over the coiled tube or tubes substantially as hereinbefore
described.
3. The combination with the water jacket of an explosion engine of a tube
bent backwards and forwards to form a cluster held together by suitable means,
of means for circulating the water from the water-jacket through the tubulous
cluster and of a fan for blowing air over the said cluster, substantially as herein-
before described.
4. In apparatus of the kind described in the preceding claiming clauses the
employment of gills or ribs substantially as, and for the purpose, hereinbefore
described.
5. The combination and arrangement of parts forming the apparatus herein-
before described and illustrated respectively in Figures 1 to 4; 5 and 6 and 7
and 8 of the accompanying drawings.
