I, ANGELIN JOSEPH MARIUS JULIEN, Civil Engineer, of 129, Rue St. Maur, Paris,
France, do hereby declare the nature of this invention to be as follows:-
The present invention relates to improvements in means for cooling water for the
purpose of cooling the sides of motors particularly of those of automatic vehicles.
The device is characterised by the arrangement in a spiral form of a flat" tube"
formed of two metal sheets united together at the sides, the said double sheet "tube"
being rolled to form a spiral, and provided with suitable inlet and outlet tubes for the
cooling water, the lateral ends of the cooling device being partly closed up in such a
manner that when the device is conveniently arranged in front of the vehicle or motor
the air which enters the spiral and passes through it in a direction at right angles
to the generatrix of the spiral escapes at both ends on arriving at the centre of the
spiral passing through it in a direction parallel to the said generatrix: in consequence
of which arrangement the quantity contained in the cooling device is very small com-
pared with the outside surface and the said outside surface is well cooled by the air
which is in contact with it almost along its whole surface.
This method of cooling also comprises the arrangement of sheets or devices partially
closing the lateral extremities of the apparatus, each being provided at its lower
portion with a hole or device serving to clean the outer surface of the cooling
apparatus.

Improvements in or relating to Cooling Devices for Motors.
ANGELIN JOSEPH MARIUS JULIEN, Civil Engineer, 129, Rue St. Maur, Paris, in the
Republic of 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:-
The devices usually employed for the purpose of cooling the water circulating
round the walls of motor cylinders with the object of keeping them cool consist,
generally, of a tube of circular section provided with external or radiating wings. In
the case of such devices the central portions of the water as it passes through, comes

page_text: but slightly or not at all in contact with the walls of the refrigerator, a condition
which renders it necessary to pass the water through a long course so that it may
part with its heat to the metallic walls, through which it travels, by conduction.
The present device is light and inexpensive, is not cumbersome and presents a
very large contact surface to the air around it, in proportion to the quantity of water
it contains.
In the accompanying drawing :-
Figure 1 represents a front view of my cooling device,
Figures 2 and 3 are a perspective view and side view, of same respectively,
while
Figure 4 represents a cross section.
In the drawing a indicates a "tube" spirally wound so as to provide a very large
contact surface in a small space, the "tube" being made of two metal sheets united
along their edges in any suitable manner.
The inner and outer edges of the spiral terminate in hollow enlargements or
tubes b 61, formed by the sheets, or otherwise and arranged parallel to the
generatrix of the spiral.
These tubes 66 are each provided at the ends with connections c c¹ by means of
which they are connected with inlet and outlet tubes of water to be cooled.
At the sides this cooling device is provided with a closing sheet of closing only
the space between the outer part of the spiral in such a manner as to leave an
orifice in the centre of the spiral cooling tube.
When such a cooling device is placed in front of an automobile vehicle with
its length at right angles to the direction of travel and the water, intended for
cooling the cylinder of the motor, is caused, by mechanical or other means, to
circulate within the cooling device, it is evident that the water will be
energetically cooled by the air which, striking the front part will freely enter
and pass along the funnel formed by the end b, the convex front part of the
spiral and the side plates ff.
This air will be driven through the whole space contained by the spiral, to the
centre of the spiral where it will escape laterally through the orifices gg in the side
plates ff, coming in contact, continuously and along the whole surface, with the
outer sides of the cooling device.
The side plates ff are each provided with a hole for the purpose of letting out
the water used for cleaning the outer surface of the cooling device within the spiral
windings.
To fix the cooling device to a vehicle it may be provided at each lateral side
with plates ii, flat or otherwise with holes for the passage of the connections c c¹
of the tubular parts 6 6¹, the plates being strengthened where the holes are formed
by plates jj.
It should be observed here, that the plates ii may be made sufficiently large
to take the place of the side plates f f¹ altogether, the former being sufficient to
close up partially the lateral sides of the cooling device, and that whatever the
dimensions of these plates i i, the side plates ff are not indispensable. In the
case of their absence the plates are made use of to attach and give rigidly
to the spiral windings of the cooling device.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
"
1. A cooling device for motors comprising a spirally bent flat "tube such as a,
made of two metal sheets suitably connected at their edges the inner and outer ends
of this spiral tube being provided with connections by means of which the cooling
device may be connected with inlet and outlet water circulating pipes while the
lateral ends of the cooling device may if desired be partially closed by sheet plates or
provided only with plates for fixing the cooling device in place and for strengthening
same; the air passing through the spiral cooling device and moving along, in a

page_text: direction perpendicular to the generatrix of the spiral and finally escaping laterally
when it arrives at the centre substantially as described.
2. A cooling device for motors consisting of a flattened wall circulating
wound in a spiral.

3. The complete cooling device for motors substantially as described or illustrated
in the accompanying drawings.
