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.
