BECAUSE of the necessity of trans-
porting enormous quantities of
grain, and the lack of laborers to handle
it during the war, a method for moving
grain invented by Robert Boby came
widely into use in Great Britain. The
inventor treats the grain as if it were
so much water. Powerful pumps suck
it up from the holds of ships or barges,
and, after cleaning it by suitable
means, distribute
it to bins, railway
cars, or trucks.
The entire plant
for doing this work
is installed on two
specially construct-
ed flat-cars. One of
the cars carries the
pumping machin-
ery, the other the
cleansing machinery. A suction pump
draws the grain through a pipe from
the hold of the ship or barge. The grain
is drawn into a reservoir on the filter-
ing car, and is discharged upon a con-
veyor which takes it to the cleansing
filter.
The sifter consists of bags of a
specially woven cotton cloth, which
may be used either dry or wet. The
wet filter bags retain the dust, which,
forming a doughlike mass, is removed”
from time to time. In the dry filter
the dust passes through the cloth,
and is blown away.
Another method of separating the
dust from the grain is sometimes used.
The grain is allowed to flow in a steady
stream into a cylinder into which a
powerful current of air is blown at an
angle to the stream of grain.
The grain is whirled around
by the current of air, which
blows the dust and chaff
out through the upper part
of the cylinder, whence it is
drawn away, and finally dis-
posed of by a fan-wheel.
The other car carries a
| gasoline engine which drives
the pumps and blowers and
the filtering-car mechanism.
