Improved Means for Cooling the Water or Condensing the Steam
from the Motors of Motor-cars.
I, PAUL ROYER, Manufacturer, of Gagny, Seine et Oise, 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 invention relates to an improved system for producing the continuous
cooling of the water of circulation which serves to cool the cyclinders employed
in vehicles actuated by motors.
This system consists in utilising the wings or mudguards of auto-inobile
vehicles, by forming these wings of sets of tubes placed side by side, the number
of which may be varied, and in which a circulation of the cooling water is
established. These tubes being struck and surrounded by the air during the
travel of the vehicle produce a rapid cooling of the water of circulation of the
motors, which in this way is subject to no loss by evaporation, whereby a travel for
an almost indefinite period may be ensured while employing a small quantity of
water without having to renew it. The vehicle is consequently relieved from the
weight and the embarrassment of a reservoir, and is further lightened from the
weight of a considerable quantity of water, and is no longer exposed to become
heated by the mass of water which the systems hitherto employed have the effect
of causing to enter into ebullition after same has been employed a certain time.
It is no longer necessary to stop in order to renew the provision of water which
has been lost by evaporation, and the motor no longer exposed to be itself arrested
in its operation by the effect of the heating of the cylinders, the decomposition
of the lubricating oils, binding of the pistons, etc.
A suitable method of applying this system is illustrated in the accompanying
drawings, in which :
Fig. 1, is a side elevation of the application of the system to an auto-mobile
vehicle.
Fig. 2, is a plan view of the complete apparatus, and shows the passage of the
cooling water, the vehicle and the wheels being removed, and
Fig. 3, is an end view of a section taken through the centre of the carriage.
It will be seen by these figures that the wings or mudguards 1, 2, 3, 4, with which
the vehicle is provided, are composed of tubes a, a, which ate of thin drawn copper,
placed side by side, and separated one from the other for {L space of about
2 millimetres, which is sufficient to allow the air to pass through, but sufficiently

fixed by supports of metal secured by their ends to the body of the vehicle. Each of
the said sets of tubes a, a, is connected together at top and bottom by a collecting
tube b with which each tube a communicates separately, and which is of a section
slightly larger than that of the other tubes a. A feed tube is arranged on one side
of each set of tulles 2 and 4 to lead the water of circulation to the head of each of the
said two tubular sets 2 and 4.-Finally communicating tubes d d', d", dm, pass
under the body and along the sides of the carriage, so as to connect the tubular wings
or mudguards with the pump P and with the cylinders C, C", in the manner to be
presently described.
is
At the upper end of each of the wings 1, 2, 3, 4, each of the collecting tubes
provided at one of its extremities with a safety valve e, to permit of the escape of the
water excessively expanded by the elevation of the temperature, and at the opposite
end with a screw plug which can be removed to facilitate the refilling when necessary.
Another screw plug is arranged at one of the extremities of the lower collecting
tube on each side so as to enable the water to be drawn off when necessary.
The pump and the cylinders C, C, are the ordinary pump and cylinders of
auto-mobile vehicles of the kind under consideration, and are only here shown in
relation to the wings and tubes constituting the complete system. Each cylinder
at its upper end is provided with a water-circulating chamber, necessary for effecting
the cooling.
The circulation of the water in the tubular wings 1, 2, 3, 4, and the communication
of these wings with each other, as well as of these wings with the pump P and the
cylinders C¹, C", is as follows
The water forced out by the pump P, passes into the circular upper space provided
at the top and round the cylinder C for the cooling; it is there heated and is sent by
the pressure, through the tube of communication d to the upper collecting tube ¿ of
the wing No. 1, from whence it flows through the dividing tubes a, e, of this same
wing No. 1, descends through same slowly and consequently cooling until it arrives
in the lower collecting tube b, from whence it passes by the feed tube c to the upper
part of the wing No. 2, subsequently through the collecting tube b, the dividing
tubes a, a, expands therein, is further cooled therein under the conditions described
for the wing No. 1 and arrives cooled through the communication tube d¹ of
the cylinder C, where it is again heated, and from whence it is forced out by the
communication tube up to the top of the wing No. 3, which it leaves at the
bottom, to be raised to the top of wing No. 4, which it descends in its turn, as has
been already described, in order to finally pass through the tube of communication di
to the suction of the pump P', and from there recommence a new cycle.
The apparatus may also be employed for condensing the exhaust steam from the
motors of steam motor cars.
Having now particularly described and ascertained the nature of any said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is.
The means for cooling the water of gas motors applied to motor cars such as herein
described and shown in the accompanying drawings, consisting in the employment of
lateral wings or mudguards, composed of bundles of tubes in which the continuous
circulation of the water and its cooling are effected, such system being also applicable
to the condensation of exhaust steam from the motors of steam motor cars, the form,
arrangement, as well as the material employed being capable of variation according to
circumstances.
