Improvements in or relating to Vehicles for the Production of Air-
currents for Ventilating and Cooling and similar Purposes.
I, ALFREDO LEBLANC, of Havana, Isle of Cuba, Engineer 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:-
My invention consists in a novel principle for utilizing the movements of any
vehicle in order to produce an artificial current of air or draught by means of any
kind of apparatuses to obtain this result.
I utilize indifferently the movements of the motors or propellers of vehicles, such
as, animals, men or engines of any kind as well as those of one or of different parts.
of the vehicle itself. With regard to engines, this current of air is intended to cool
the overheated parts of same.
These motions actuate either ventilators, bellows, fans or any other apparatuses
of any shape and disposition capable of producing ventilation.
The object is to refresh the motors or propellers such as, beasts, men or any other
things requiring air. Its advantages are to allow the said motors or propellers and
things to last and resist longer, to produce a greater useful effect and more labour
with more economy.
It will be easily understood that a large number of appliances can be used, but
in order that my invention may be clearly understood I am now going to describe
as instances, several very simple applications of same.
Firstly Fig. 1 is a section and Fig. 2 a side view of an arrangement for utilizing
the movements of a horse to actuate a fan.
A in Figs. 1 and 2 illustrates the fan placed upon vertical rods P. P. the fulcrums
of the fan upon said vertical rods having free joints in K. K. so as to swing from
right to left see Fig. 1.
The vertical rods P P are fixed either to the vehicle or to the shafts S. S. Figs. 1
and 2, B is the lever-arm of the rod K. K. forming part of the fan A. The rod T
is fixed by its lower end either to the propeller or to the rump of the horse C (Figs. 1
and 2) or to the harness for instance, and its upper end (having also movable joints)
is connected with the lever-arm B. It is easy to understand that the downward
and upward motion of the horse's rump when trotting is thus transmitted to the
fan A in a sideways reciprocating motion by the rod T and the lever arm B. This
transmission of the horse's movement to the fan will produce an artificial current
of air or draught upon the body of the animal. It is understood that the apparatus
can be adapted to any other part of the body of the horse or of any other propeller
and can also receive the motion from any other part of the body of the motor or of
the vehicle.
Secondly, one of the movements of the vehicle can be utilized, for instance, the
rotary motion of the wheels by actuating any ordinary bellows.
Fig. 3 illustrates the side elevation and Fig. 4 the top view of this appliance.
A are ordinary bellows fixed to any part of the vehicle either to the box C Fig. 3
or to the axle of the wheels. At the centre of the wheel or wheels are adapted
friction pulleys or gearing D. D. or any other suitable wheels for transmitting the
rotary motion to the wheels E. E. Figs. 3 and 4 fixed upon a crank shaft H which
when rotating communicates reciprocating motion by means of the shaft or
connecting rod K to the bellows A Fig. 3 and thus causes it to work. The
bellows A Fig. 3 force the air through pipes or tubes T Fig. 3 which distributes

the air to the desired parts either to the motor or propeller such as man or horse or
to any other objects desired to be aired or ventilated.
Thirdly the rotary movement of the wheels for producing ventilation can be also
applied to work any rotary ventilators.
Fig. 5 illustrates the side section of a vehicle and Fig. 6 the top view of the
wheels of the vehicle provided with the rotary ventilator.
To the centre of the wheels B are adapted friction or toothed pulleys or
wheels C. C. in such a way as to transmit their motion to the pulleys D. D. of a
ventilator H Figs. 5 and 6. The wheels B. B. of the vehicle when rotating by
means of the said pulleys or wheels C. C. and D. D. (in lesser or greater number to
effect the necessary revolutions) transmit the rotary movement to the ventilator H
Figs. 5 and 6 which force the air and at the same time distribute it through
pipes T on the parts of the motors or propellers or on any other objects to be
ventilated.
Finally it is to be understood that the fan, as well as the bellows, ventilators or
any other ventilating apparatuses can be disposed in any manner, number or shape.
It is also evident that these apparatuses can be engaged or disengaged i.e. be set
in motion or stopped at will, whilst the vehicle or the propeller are running.
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
The application to vehicles or any motors of certain apparatuses or appliances
of any determined shape or dispositions and also the utilizing of the movements of
any vehicles, motors or propellers to produce artificial ventilation by means of any
apparatuses whatever adaptable to that said purpose.
