and movable throw-off carriage the grain can be deposited on any floor of the granary
from the one band conveyor at the top. There is a second band conveyor on a lower
floor, which Will take the gram from any of the floors, either to the elevator to be asain
elevated, or to be loaded. The second elevator is in the middle of the building, and can
also, by means of an alternate spout, deliver to the hopper over the cleaning machine
whence the grain reaches the second hopper, the lower portion of which is fitted with å

Granaries at Breslau.—These were also designed by Rudolf Dinglinger. The
i ustrations, Figs. 972 to 975, show a longitudinal section through the whole of the
g,ran®7’, ,aS wel as thJee cross sections. The cleaning plant is installed in the centre of
the budding, grain being stored on either side. One wing is provided with silos, the
other is used for storing grain on the floors. Since these granaries were designed, how-
ever, the scheme has been so far modified that the silos have been superseded, the grain
being stored only on the floor of the warehouses, the entire granary being fitted with
noor bins.
Grain is received at the centre of the building exactly in front of the cleaning
apartment, either by rail, or by means of one of two barge elevators. After being
elevated to the top of the building, it may either be passed through the cleaning plant0
or it may be carried by a band conveyor to either of the wings to be stored The ton
band conveyors are fitted with throw-off carriages, so that any part of the granary can
readily be served. The lower strands of these band conveyors are also used for with-
drawing gram and feeding the cleaning plant, which consists of a warehouse separator
with a full system of cockle and barley cylinders for eliminating any seeds from the
grain which, when received, and prior to its delivery to either of the two elevators is
passed through an automatic weighing machine. There are also further automatic
weighers through which the grain is passed before being sacked.
The barges can be brought alongside right under the receiving elevator, where they
are discharged, as shown in the illustration, Fig. 975. This elevator is 36 ft. long from
. centre to centre, and has a capacity of 40 tons per hour. It is so arranged that it can
be lowered or raised to the level of the grain in the barges, and can also adjust itself to
the water level of the river. The delivery of the elevator always takes place at the same
spot. Prom this point the grain is removed through a spout to a second elevator, which
in turn delivers it to the automatic grain scale, whence it passes through a grain-cleaning
machine known as a warehouse separator, where it is again spouted to" the elevator
shown in the centre of the grain warehouse.
The receiving grain elevator can be raised or lowered by. a small winch. The
elevator itself is one of the chain type, with sprocket wheels at top and bottom, the
framing being substantially constructed of angle iron and timber.
r The wheat elevated from the barge is, of course, in an unclean condition: the
weighing machine, however, keeps an accurate record of all material, dirty or otherwise,
