PROVISIONAL SPECIFICATION.
Improvements in Mechanically Driven Road Vehicles.
I, EMILE DELAHAYE, of 21 Boulevard Poissonnière, Paris, in the Republic, of
France, do hereby declare the nature of this invention to be as follows:-
In vehicles driven by a petroleum or like motor a certain quantity of water is
generally used which serves for cooling the cylinder or cylinders of the motor.
This water is circulated about the parts to be kept cool, either by means of a
thermo-syphon or, in most cases, by the aid of a small pump provided for the
purpose. Whatever may be the means employed, it is frequently necessary to
replace, a certain quantity of water in the reservoir, because by its contact with'
the hot cylinders the temperature of the water rising to the boiling point
becomes vapourized; thus causing considerable inconvenience and loss of time.
The object of this invention is to render the motor independent of the frequent
renewal of water.
The front of my vehicle is provided with a splashboard arranged to deflect the
wind. In the space between the splash board and the front axle I provide a
multitubular refrigerator, the superficial area of whose tubes is properly calculated
and on the top of it I fix the water reservoir.
The water from the reservoir is forced by the pump in the manner I have before
referred to, into the jacket of the cylinders whence it issues into the refrigerator
coil which it traverses and then re-enters the water reservoir.
By reason of the speed of the vehicle and of the arrangements adopted for the
water receptacle and the refrigerator, a strong air current constantly traverses these
devices, and there results a difference of temperature sufficient, even during the
warmest weather to prevent the evaporation of the circulating water and thus to
allow of the completion of a journey without the necessity of replacing evaporated
water.
The shape of my refrigerator may vary, according to the arrangement and the
space available. The arrangement I have adopted, for my vehicles is most suitable
for the reasons indicated. But for other types of vehicles the refrigerator is equally
efficient when located above or below the wheel splashboards, at the side of the body
of the vehicle or elsewhere.
Instead of causing the water to circulate in the tubes, the air may traverse
them while the water circulates around them; this however is a matter dependent
on the arrangement of the vehicle or other circumstances.
Whatever may be the form, arrangement or position adopted for this device the
combination of, my multitubular refrigerator with the water receptacle constitutes
an efficient means whereby the same water is made to serve almost indefinitely.

I, EMILE DELAHAYE, of 21 Boulevard Poissonnière, 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 :-
In vehicles driven by a petroleum or like motor a certain quantity of water is
generally used which serves for cooling the cylinder or cylinders of the motor.
This water is circulated about the parts to be kept cool, either by means of a
thermo-syphon or, in most cases, by the aid of a small pump provided for the
purpose. Whatever may be the means employed, it is frequently necessary to
replace, a certain quantity of water in the reservoir, because by its contact with the
hot cylinders the temperaturo of the water rising to the boiling point becomes
vapourized; thus causing.considerable inconvenience and loss of time. The object of
this invention is to remedy these. inconveniences.
In the accompanying drawings
Figure 1 represents a sectional elevation of so much of a vehicle as is necessary
to illustrate my invention.
Figure 2 is a plan of the front axle and cooling apparatus with the body of the
vehicle removed and
Figures 3 and 4 show a vertical section and plan respectively of a slightly
modified form of the device.
The front of my vehicle is, provided with a splashboard a arranged to deflect the
wind. In the space between the, splash board a. and the front axle I provide a
multitubular refrigerator d the, superficial area of whose tubes is properly calculated,
and on the top of it I fix the. water reservoir c.
The water from the reservoir.c.is. forced by the, pump, in the manner I have before
referred to, into the jacket of the cylinders whence it issues. into the refrigerator
coil d which it, traverses and then re-enters the water reservoir c.
By reason of the speed of the vehicle and of the arrangements adopted for the
water receptacle and the refrigerator, a strong air current constantly traverses these
devices, and there results a difference of temperature sufficient, even during the
warmest weather to prevent, the evaporation. of the circulating water and thus to allow
of the completion of a journey, without the necessity, of replacing evaporated water.
The shape of my refrigerator may vary, according to the arrangement and the
space available. The arrangement I have adopted, for my vehicles is most suitable
for the, reasons. indicated. But for other types of vehicles the refrigerator is equally
efficient when located above or below the wheel splashboards, at the side of the body
of the vehicle or elsewhere.
Instead of causing the water to circulate in the tubes, the air may traverse 'them
while the water circulates, around them; this however is a matter, dependent on the
arrangement of the vehicle or, other. circumstances.
Whatever may be the form, arrangement or position, adopted for this device the
combination of my multitubular refrigerator with the water receptacle constitutes an
efficient means whereby the same water is-made to serve almost indefinitely.
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
claim is :-
1. In a vehicle driven by a petroleum or like internal combustion engine, a system
of circulating pipes or tubes in combination with a water reservoir, substantially as,
and for the purpose. described.

page_text: 2. The improvement in mechanically driven road vehicles substantially as described
with reference to the accompanying drawings for the purpose specified.
