1for there hangs no pump-rod from the
iron key of these claws, for it can be of
no use in the last pump. In turn, when the first pump-rod descends, each
set of “claws” is lowered, each pump-rod and each piston-rod. And by this
system, at the same time the water is lifted into the tanks and drained out of
them; from the sump at the bottom of the shaft it is drained out, and it
is poured into the trough of the tunnel. Further, around the main axle there
may be placed two water wheels, if the river supplies enough water to turn
them, and from the back part of each round iron crank, one or two pump-rods
can be hung, each of which can move the piston-rods of three pumps.
Lastly, it is necessary that the shafts from which the water is pumped out in
pipes should be vertical, for as in the case of the hauling machines, all pumps
which have pipes do not draw the water so high if the pipes are inclined in
inclined shafts, as if they are placed vertically in vertical shafts.
