This rendered it necessary to give up the idea of
using a belt, since it was not possible to prevent its getting wet. Cords
could not be found in the country, and so it was necessary to make use of
a too heavy chain, which was in no wise intended for such a purpose, and
which at a velocity of 15 revolutions began to swing and necessarily
absorbed much power. The large pulley drove one of 0.4 m. upon an
intermediate shaft. Upon this latter a 2.6 m. wooden pulley directly
drove, through a belt, the 0.2 m. pulley of the generatrix.
From this may be judged what the country's resources are. The motor, by
means of a belt, actuated a windlass provided with suitable checking
gearings. The distance of the two machines was 116 meters. Save the
transmission by chain, the whole worked in a satisfactory manner. The
performance could only be estimated in a lump, by comparing on the one
hand the theoretical work of the fall of water, and, on the other, that of
the vertical elevation of the car; and, further, one was obliged to
estimate the weight of the latter. If we allow 1,000 kilogrammes for the
weight of a car that received 360 liters of dry sand or 300 of wet, the
performance was 19 per cent.
