The wmnotring machine under the shakers is driven by a sheave on the drum axis, and a ropoleading to a sheave on the fanner spindle ; to dress the grain thoroughly, it is conveyed from thismachine, and passes through two winnowing machines, one placed above the other: this is effected bymeans of a canvass cloth, on which are strips of wood half an inch in thickness ; the cloth revolves ontwo rollers, and is set in motion by a rope leading from a sheave on the shaft i to a sheave on the upperroller spindle.
