When the grain is elevated to
the point whence it is to be transferred to the granary, railway
truck, or other destination, the band travels horizontally on suitable
bearings, the buckets being so constructed that in traveling they retain
their load intact. The contrivance for lengthening and shortening the
bucket band is an application of the "lazytongs" device, which is well
known. The float of the elevator is shown at the left hand of the
engraving, and, as seen in the latter, there is an automatic weighing
machine, by which the material may be weighed as it is delivered, before
it goes to the bottom of the elevator, to be again transferred by its
means to the barge or granary. Simplicity, efficiency, and adaptability
to any position in which elevators of this class are desirable, are the
claims the patentees, Messrs. Behrns & Unruth, Lubeck, make for the
advantages of their apparatus.--_London Miller_.

IMPROVED DREDGER.
We illustrate below a useful type of dredger made by Messrs. Rennie, of
Blackfriars, England. The drawing almost explains itself. The machine
consists of a double barge or pontoon, in which is erected a derrick.
This derrick works a "spoon" dredge at the end of a lever.
