Abstract
The construction of a retort for extracting or distilling coal oil or other products from cannel coal, shale, or schist, and more particularly of small coal or dust technically called slack, consists in applying self-acting feed and discharge apparatus to a revolving cylindrical wrought or cast iron retort, and constructing the inner surface of the cylindrical retort with a projecting ridge which encircles the interior of the retort in a spiral manner, the same as the interior of a female screw, and the ridge may be either cast upon or riveted on the internal surface, and is so arranged to cause the material to be operated upon to advance from one end of the retort to the other, as the retort revolves by following the course of the spiral screw or worm formed by the projecting ridge.
