ENDLESS TROUGH CONVEYER.


[Illustration]

The endless trough conveyer is one of the latest applications of
link-belting, consisting primarily of a heavy chain belt carried over
a pair of wheels, and in the intermediate space a truck on which the
train runs. This chain or belt is provided with pans which, as they
overlap, form an endless trough. Power being applied to revolve one of
the wheels, the whole belt is thereby set in motion and at once
becomes an endless trough conveyer. The accompanying engraving
illustrates a section of this conveyer. A few of the pans are removed,
to show the construction of the links; and above this a link and
coupler are shown on a larger scale. As will be seen, the link is
provided with wings, to form a rigid support for the pan to be riveted
to it. To reduce friction each link is provided with three rollers, as
will be seen in the engraving. This outfit makes a fireproof conveyer
which will handle hot ore from roasting kiln to crusher, and convey
coal, broken stone, or other gritty and coarse material. The Link Belt
Machinery Company, of Chicago, is now erecting for Mr. Charles E.
Coffin, of Muirkirk, Md., about 450 ft. of this conveyer, which is to
carry the hot roasted iron ore from the kilns on an incline of about
