Haggenmacher's patent "consists of an improved machine for separating the different qualities of semolino, middlings, corn, and other seeds, the parts of which machine are so constructed and arranged that the matters to be treated, when fed into it at the upper part, pass downward by gravity, and are acted on during their passage by a current of air drawn or forced through the machine, the said current of air separating the semolino or other matters into different qualities, each of which passes from the machine by a separate chute."
