The four-story house on top of the granary contains a number of
different mechanisms. In the uppermost flat the leg’s revolving
belt turns round a pulley and discharges the grain into a receiving
hopper on the next floor. From this it is withdrawn to the weighing
hopper, nicely balanced on a Fairbanks beam-scale, having a capacity
for 30,000 pounds or 500 bushels of wheat, which is weighed with as
much exactitude as is a pound of tea by the grocer. At either end of
this room there is a separating machine in which the grain can be
thoroughly cleansed by the removal of smut and dust. Underneath is the
distributing room, with jointed pipes leading to the storage bins, of
which there are one hundred, each 50 feet deep and 12 feet square,
calculated to hold 6,000 bushels each. The process of withdrawing the
grain from the bins, strange to say, is a repetition of that just
described. It must go down into the cellar, and up again to the attic,
and pass through the weighing machine and thence to the car, the barge,
or the ship. A car of 600 bushels can be loaded in three minutes. The
most singular part of the whole apparatus is the “carrier” by which the
grain is conveyed from the elevator to the vessel lying at the wharf,
260 feet off. The carrier is an endless four-ply rubber belt, 515 feet
long and 36 inches wide, upon which the grain is dropped and carried
to its destination. The difficulty of comprehending why the grain is
not shaken off that flat, rapidly revolving belt is not lessened by
the explanation given, that it is held in place by the concentrative
attraction of the particles in motion. But from whatever cause, the
grain clings to the belt, and may be carried in this way any distance,
and in all manner of directions, turning sharp corners and even going
over the roofs of houses if they stand in the way. The elevator in
question delivers by “carrier” from 8,000 to 10,000 bushels an hour.
There are over 50 such elevators in New York, only of much larger
capacity; Buffalo has 52, with a storage capacity of over 15,000,000
bushels; Chicago, 21; Duluth and Superior, 9 each. There are elevators
in Buffalo that can take grain out of a vessel at the rate of 25,000
bushels an hour.
A Duluth paper of May 21st, 1898, says: “Globe elevator No. 1 carries
the broom for rapid loading this year, and the record made yesterday
has probably never been equalled. The steamer _Queen City_ loaded there
yesterday morning, taking 185,000 bushels in 180 minutes.”
