DUSTLESS OAT SEPARATOR AND ZIGZAG. With two or four Wheat Riddles and Cockle Riddle.

Patented April 9, 1861; Re-issued, April 19, 1871.

This Machine is named “Dustless Separator,” because the Dust is separated from the wheat, conveyed out of the mill, and deposited in a dust room, before the grain passes to the riddles; the wheat and screenings are left free from dust.

Its operation is as follows:—The grain enters the Machine at the hopper, which is shown, where it receives the first blast; then passes through two to four wheat riddles in succession, and over a cockle riddle into the second blast. The riddles deposit oats, sticks, weeds, ergot, rat-balls, etc., in suitable spouts; the heavy screenings fall into a hopper and are spouted off. This Machine has none but suction blasts, and is offered to the milling community as a first-class Separator.
