As the driving belts are mounted on pulleys, G, of a diameter
proportioned to the velocity of the shafting, the iron pinions, h, in
order to produce 60 revolutions per minute in the first shaft, H, gear
on each side with the intermediate wheels, E, and these actuate the
two bronze pinions, a a, that are mounted on the extremities of the
cylinders, A A. The axle, D, of the intermediate wheels does not revolve
with them, but is capable of rising and descending in the elongated
aperture that traverses the frames, B. The displacement of this axle is
secured through the arms, L L, whose extremities articulate on the one
